IN MEMORY OF MANY YEARS OF FRIENDSHIP THIS BOOK IS DEDICATED BY THE AUTHOR I b L.'?75'£ PREFACE TO THE FOURTH EDITION. The third edition of this work, pubhshed in 1885, Avas intended to present to the reader a picture of the most advanced obstetrical teachings of that date. In the brief interval, liowever, that has elapsed since then the changes that have taken place in both the theory and practice of obstetrics have made it necessary for me to present to the profession what is essentially a new book. Thus many modifications in the theory have resulted from more careful observations in anatomy and pathology, and from fruitful physio- logical investigations. It has been my endeavor to interweave aseptic precautions with all branches of obstetric art without, how- ever, insisting upon pedantic measures which experience has shown to be needless. But the noblest conquests of the past years have been the result of the employment of modern surgery for the relief or removal of a host of complications formerly regarded as beyond the pale of human help. In making needed alterations I have not felt it obligatoi-y when new discoveries have destroyed the value of former deductions to retain these in order to maintain a reputation for consistency. I thank the medical press and the medical profession of this countr}^ and Great Britain for the flattering welcome they have hitherto extended to this treatise, and trust that in its new form it may connnand a like degree of favor. For the preparation of the index special thanks are once more due to my friend Dr. W. H. Flint, whose painstaking accuracy will be evident to those who have occasion to consult these pages.

Increase of angle between symphysis ami pelvic bnm 4ey vaginam, as though the anterior lip were really the shorter of the two. This absolute superior length of the anterior lip, combined with the natural oblique direction of the uterus, causes the external orifice to look nearly directly backward, a fact which is readily recognized when the organs are examined in situ by means of a Sims's .■speculum. Upon lateral section, the uterus is found to be provided with a cavity, in which the upper portion or cavity of the body is to be dis- tinguished from the lower portion or canal of the cervix. The cavity of fJte body presents a triangular shape with convex borders. The two upper angles communicate by a small opening, hardly large enough to admit a fine bristle, with the canal of the Fallopian tubes. At the lower angle is situated the os internum, a circular orifice, large enough to admit a uterine sound, which forms the internal anatomical limit between the body and the cervix. The canal of the cervix has a fusi- form slia])e, and is included between the internal and external orifices ah-eady described. Its inner surface is characterized by two longitu- dinal ridges, occupying the anterior and posterior walls, from which Fig. 8.— a, muciparous uterus, anterior surface ; B, uterine cavity. (Sappey.) branching processes extend obliquely upward, giving rise to an appear- ance which justifies the title — arbor vitce uterina. In women who have borne children, the uterus measures three inches in length, of which nearly two inches belong to the body and one to the cervix. There is increased convexity of the fundus. The distance u PHYSIOLOGICAL ANATOMY. between the insertions of tlie Fallopian tubes measures over two inches. The width of the cervix, at its Junction with the body, measures one inch. The uterus thus assumes a pyriform shape. The cavity of the uterus loses its triangular character, and assumes a more ovoid ap- pearance. The external orifice no longer forms a smooth transverse depression, but its edges, lacerated by childbirth, communicate the impression of a rounded, puckered surface. When a profile section is made through a perfectly healthy unim- /^^pregnated uterus, its walls are found in actual contact. A cavity does not, therefore, naturally exist. The uterus is so situated in the pelvic cavity as to possess a large degree of mobility. Its lower extremity projects, as we have seen, into Fig. 9. — Virgin uterus opeuecl posteriorly, showing at A, A', the os internum ; at O, e, os exter- num ; P, peritoneal folds. (Bandl.) the vagina. The supra- vaginal portion of the cervix is attached anteri- orly to the walls of the bladder. That portion of the uterus which ex- tends freely into the pelvic cavity is covered by a reflection of the pe'ri- tonseum, precisely as though the uterus had been pushed from below upward into the peritoneal sac. Thus the peritonaeum covers the uterus anteriorly and posteriorly. Its two surfaces meet at the lateral borders of the uterus, and thence spread outward to the ilia of the respective sides. These peritoneal folds divide the pelvic cavity into two nearly equal halves, and are termed the Ugametita lata, or broad ligaments. Two peritoneal folds, containing a few contractile fibers derived from the muscular tissue of the uterus, pass forward from the uterus FEMALE OUGANS OF GENERATION. 15 to the bladder — the pUcce vesico-ntcrince. These folds form the sides to a space, limited anteriorly and posteriorly by the bladder and uterus, termed the excavatio vesico-uterina. Upon the posterior surface, the peritoniBum descends down not only over the entire supra- vaginal portion of the uterus, but over that portion of the vagina which covers the posterior lip of the intra-vagi- nal portion. Thence it curves upward, and becomes continuous with the peritoneal investment of the rectum. Thus a deep cul-de-sac is formed between the uterus and the rectum, known as the excavatio recto-utevina^ or cul-de-sac of Douglas. Two lateral folds of peri- tonaeum likewise pass from the uterus to the rectum, which form sides to this space, the ^^//Vvp yerfo-uterina>. These folds inclose in their Fig. 10. — Uterus of a woman wlio has borne children.

(Bandl.) free borders contractile muscular fibers, derived from the uterus and vagina. The plicae recto-uteri nae pass backward, near the rectum, to the neighborhood of the second sacral vertebra. As the muscular fibers they contain were believed by Luschka to fulfill the function of maintaining the uterus in a state of normal anteversion, he proposed that they should be termed the retractores uteri. In Figs. 9 and 10, copied from Bandl, it will be noted that in the virgin uterus the upper borders of the peritoneal folds which bound laterally the cul-de- sac of Douglas leave the uterus at a point corresponding very nearly to the site of the os internum ; whereas, in the uterus of women who have borne children, the os internum is situated at a considerable jg PHYSIOLOGICAL ANATOMY. distance below the folds, a difference whicb Baudl believes to be due to an expansion of the upper portion of the cervical canal by the growth of the ovum during pregnancy, the expanded portion thereafter form- ing permanently an addition to the uterine cavity. The peritonaeum covering the uterus is an exceedingly delicate membrane. Over the body. and fundus of the uterus, both front and rear, it adheres intimately to the muscular tissues, while below the level of the recto-uterine folds, where the subperitoneal connective tis- sue is more abundant, separation is easily effected. Though it may be proper to speak, in a general way, of the uterus as occupying a position coincident with the axis of the superior pelvic strait, it must be borne in mind that, in reality, its position is largely influenced by the neighboring organs. Thus, a full bladder pushes the fundus backward. A full rectum shoves the cervix forward. When bladder and rectum are both evacuated, the resiliency of the muscular fibers in the recto-uterine folds produces a limited amount of ante- version. Marked degrees of anteversion or anteflexion following the evacuation of the bladder are abnormal, and are due either to fixation of the cervix resulting from inflammatory changes in the parametrium, to increased size of the uterus, or to the loss of the muscular tomis. The uterus is composed of muscular fibers of the unstriped variety, arranged in bundles and united together by delicate processes of con- nective tissue. In the non-gravid, but more distinctly in pregnant and puerperal, uteri the arrangement of the muscular fibers in three layers is indicated, though the layers are not absolutely separable from one another. 1, The superficial layer covers tlie anterior and posterior surfaces of the uterus like a hood, while the sides are left free. It possesses a membranous thinness, and is intimately adherent to the peritonanim. Its fibers, a part of which are continuous with the longitudinal fibers of the external muscular layer of the Fallopian tubes, pursue an appar- ently circular course in the neighborhood of the tubes and a longitu- dinal direction near the median line. The continuity of the outer layer is, however, broken by the inser- tions of the retractor muscles, and of the ovarian and round liga- ments. The ovarian ligament is a broad band, measuring about an inch in length and a fifth of an inch in width, which passes posteriorly from the upper lateral portions of the uterus between the layers of the broad ligament to the ovary. The round ligament, a muscular bundle of rounded form, passes from the anterior uterine surface near the in- sertions of the Fallopian tubes between the peritoneal folds of the broad ligament and through the inguinal canal to the symphysis pubis, where its fibers terminate in the connective tissue of the mons Veneris. The round ligament is four to five inches in length, and in the unim- pregnated condition, when the fundus is depressed below the pelvic FEMALE ORGANS OF GENERATION. lY brim, runs in a curved direction upward, outward, and forward, to gain the inguinal ring. 2. The median layer constitutes the great bulk of the uterine walls. It is composed of longitudinal and transverse fibers which form an in- tricate interlacement, in the meshes of which are contained the vessels of the organ. In pregnancy the arrangement of muscular bundles in superimposed leaf-like plates or lamella3 is observable. These start in the fundus and body of the uterus from the peritonaeum, to which they are firmly attached, and at first the fibers are in close proximity. They soon, however, split into bundles, which follow, in most cases, an oblique course downward and inward to the uterine mucous membrane. In the lower uterine segment, i. e., the inferior convex portion of the uter- ine cavity, which in pregnancy and childbirth is subjected to the dis- tending influence of the presenting part, th§ muscular lamellae — seven to ten in number (J. Veit) — are attached to the peritonaeum by means of loose connective tissue. They send fibers in part to the connective tissue of the cervix, and in part to that which surrounds the upper vaginal walls. 3. The inner layer is of extreme tenuity. Its fibers pursue a sjii- roidal course around the orifices of the tubes. Between the latter and the internal os the fibers of the inner layer form on the anterior and posterior surfaces beneath the mucous membrane a triangular muscle, and extend downward into the cervix. During j^regnancy the triangu- lar muscles, owing to their fixation at the internal os, do not follow the expansion of the uterine cavity. The underlying transverse fibers are therefore exposed upon the lateral walls, a con- dition which persists, after involution is com- plete (Bayer). The cervical walls are composed mainly of connective tissue. The muscular structures of the cervix are derived from the lamella? of the lower segment, from the inner layer of the uterus, and from the fibers which accompany the distribution of the vessels. Upon the outer surface of the cervix, just at the point of the vaginal attachment, there is a well-developed layer of transverse muscular fibers. Circular vessels, imbedded in a loose- meshed connective tissue containing wide lym- phatic spaces, surround the cervix at the same point. Thus a ridge is formed, which is greatly augmented in size during pregnancy. In the cervix, the connective tissue exists in the form of well-differ- entiated fibers of the ordinary variety. In the body of the uterus, a similar loose-meshed, wavy connective tissue is found in the external 2 Fig. 11.— S<'ction tlirougli tlie mucous membrane of a normal virgin uterus, magnified about forty di- ameters (Kundrat and En- gelmanni.

In the median layer, rings of connective tissue accompany the vessels, while fibers of the finest description penetrate between the muscular bundles. Fine fibers, of a like char- acter, but more abundant, are found in the inner muscular stratum, whence they pass directly into the connective tissue of the mucous membrane. The mucous membrane of the uterus is divided into that lining the body and that which lines the cervical portion, between which charac- teristic differences of structure exist. TJie mucous memhrane of the hodij is smooth and soft. ^ At the fun- dus and upon the sides it measures about ^j of an inch in thickness, but is thinner in the vicinity of the tubes and the cervical portion. It is covered, under nor- mal conditions, with a thin layer of transpar- ent alkaline mucus. AVhen examined with a magnifying-glass its surface presents a per- forated appearance, due to the openings of the uterine glands. These glands are of the tubular variety, have a sinuous course, and are oftentimes divided below into two or three separate blind extremities. They extend, in the rule, through the entire thickness of the mucous membrane, and, in rare instances, penetrate into the muscular tissue of the uterus. They possess a delicate basement membrane, composed of spindle-shai)ed cells, which dovetail into one another like the endo- thelium of the capillaries and lymphatics.* They are lined by cylindrical cells which are said to possess cilias. The mucous membrane of the body of the uterus possesses an epi- thelium of the ciliated variety, which produces a current in the direction of the Falloi)ian tubes, f A very irregular capillary net-work, with delicate walls, extends between the glands, and passes near the free surface into venous radi- cles, which furnish during menstruation the source of venous haemor- rhage. The intermediate space is filled up by a connective-tissue mesh-work, composed of fine processes and spindle-shaped cells, whose nuclei im- * Leopold, Die Lymphgefasse des normalen nicht schwangeren Uterus, Arch.

Leopold * claims for this mesh-work the.signiticance of lympli-siniises. The close attach- ment of the mucous membrane to the muscular tissue is explained by the direct continuity of the connective tissues of the two structures. The mucous memhrane of the cervix is of a yellowish-red color, of ai firm consistence, and possesses the penniform ridges already described. It is therefore readily distinguished, both by the eye and the touch, from the red, smooth, velvety structure of the mucous membrane lin- ing the body. At the time of puberty it possesses a ciliated, cylindri- cal epithelium, which extends down to within from two to three lines of the OS externum. f Simple gland-tubes, and glands with multiple cuJx-dc-sac, are found upon the crests and sides of the ridges and upon those portions of the cervical canal in which ridges do not exist. These glands are, genetically considered, simple inversions of the mucous mem- brane, and are lined by ciliated epithelium. When the neck of one of these glands becomes obstructed, the secretion accumulates, and forms the straw-colored vesicles which have been termed the ovula of Nabotli. Papillary structures, of clavate shape, are very numerous in the lower half or third of the canal. According to Lott,J a section through one of these papilla3 is not to be distinguished from a section through one of the smaller folds of the arbor vitai uterina. The cervical mucous membrane affords thus an extensive secretory surface, furnishing an alkaline mucus, Avhich" possesses important physiological functions in connection with conception, pregnancy, and labor. The Fallopian Tubes. — The Fallopian tubes, as the history of their develo^iments goes to demonstrate, are, strictly speaking, integral por- tions of the uterus. A glance at Fig. 14 will serve to make apparent the continuity between the tissues of the uterus and those of the Fal- lopian tubes. It will be noticed, too, that the canal of the latter com- mi;nicates directly with the uterine cavity. The Fallopian tubes meas- ure from three to four inches in length. They are included between the folds of the broad ligament at its upper border. As they pass out- Avard from the uterus they follow a somewhat sinuous course, and gradu- ally increase in width and thickness. The free extremity possesses an opening communicating with the abdominal cavity, the ostiinn abdomi- nale, which is large enough to admit a small goose-quill {2"), whereas the uterine opening does not exceed ^ of an inch in diameter. Henle designated the inner, narrower half, which runs a comparatively straight course, the isfhmus, and the outer, sinuous, dilated portion the amjmlla of the tube. A number of ragged, fringe-like processes surround the ostium abdominale, whence the name fimhriated extremity of the ttibe. These fringes received likewise from the mediaeval anatomists the name * Op. cit., p. 47. t LoTT.

They are arranged in three layers : two, longitudinal, continuous respectively with the external and internal layers of the uterus ; and one, circular, continuous with the circular fibers of the inner uterine layer. Galvanization of the tubes causes contractions of a vermicular character. Between the muscular walls and the peritoneal covering there is a connective-tissue layer, which gives support to a rich plexus of blood- vessels.

(Luschka.) The mucous membrane of the tubes is extremely vascular, and has a ciliated epithelium, which produces a current in the direction of the uterus. It presents numerous longitudinal folds, which are much more complicated in the ampulla than in the isthmus. In the ampulla these folds possess an arborescent character, as may be seen in Fig. 15. The Ovaries. — The ovaries are two flattened, nearly ovoid bodies, situated between the layers of the broad ligament. They measure from one to one and a half inch in length, from three fourths of an inch to an inch in breadth, and from a third to a half inch in thick- ness. Each' ovary is connected with the uterus by a muscular band about an inch in length and a fifth of an inch in width, termed the ligamcnium ovarii. 90 PHYSIOLOGICAL ANATO Jl Y. Previous to pxTbortv tlie ovaries present a siiiootli surface, but after maturity tliey become' uneven and corrugated from the enlargement, rupture^ and'cicatrization of the Graafian follicles. Although the ovaries are said to be of ovoid shape, in reality one border is much more convex than the other. The comparatively straight border is attached to the posterior surface of the anterior layei^of the broad ligament. The posterior layer of the broad liga- ment is reflected over the entire ovar^j, Avith the exception of the at- tached l)()rder, at which point tlie hilum, or opening, is situated. through which the sper- matic vessels, which are in- cluded between the folds of the broad ligament, find entrance into the sub- stance of tlie organ. Wal- deyer * has shown that an abrupt change in the chai-- acter of the epithelium from the pavement to the cylindrical variety takes place where the perito- naeum reaches the hilum of the ovary. At this point, too, the connective tissue of the serous mem- brane ceases to form an independent layer, easily separable from the under- lying tissues, but becomes lost in the stroma of the ovary. When the broad liga- ments are removed from the body, and held as nearly as possible in the natural position, the con- vex border of the ovary looks downward. If the broad and ovarian liga- ments are, however, put upon the stretch, the convex border rises and looks directly backward. The ovary is found, upon section, to contain a fibrous stroma, the * "Waldeyer, Eierstock uud Nebeneierstock, Strieker's Handbuch der Lehre der Geweben, p. 545.

Externally, the ovary is surrounded by a fibrous coating, the so- called tunica albuginea. In the first three years of existence, how- ever, the albuginea is wanting. Even in a state of complete develop- ment, it can never be stripped off as a separate layer, but is always intimately adherent to the subjacent tissues. Beneath the albuginea the parenchyma of the gland is further divided into an outer cortical and an inner medullary substance. The medullary substance has a spongy texture, and is of a reddish color. It contains an abundance of blood-vessels, the branches of which pursue a spiral course. The cortical subi^tance is of a grayish color. In it a multitude of small follicles, of the utmost functional impor- tance, lie imbedded. The precise description of these follicles will be given in connection with the subject of ovulation. The stroma of the cortical substance is nowhere sharply distinguished from that of the medullary portion. The fibers of the stroma, for the most part, radi- ate from the center toward the circumference. Just underneath the albuginea, however, the connective tissue of the cortical substance pre- sents a felted arrangement. This portion is termed in the illustration (Fig. 16) the fibrous layer, in contradistinction to the more central portion, which is largely composed, in the neighborhood of the vessels and the follicles, of round and spindle-shaped cells. The Vessels of the Uterus and its Appendages. — The uterus receives its arterial supplies from the following sources: 1. The arferia nter- ina liypofiasfrira. This artery, as its name implies, is derived from the hypogastric. It first pursues a downward course to reach the vagi- nal fornix, where its pulsations may be felt during pregnancy. Thence it curves upward between the folds of the broad ligament, and follows a tortuous course along the lateral borders of the cervix and corpus uteri. It distributes small branches to the fornix vaginae, and large ones to the uterus. Tlie uterine branches are, in part, distributed to the surface of the uterus, and, in part, penetrate the muscular tissue, to form a thick capillary net-work immediately under the uterine mu- cous membrane. Of surgical interest is a circumflex branch, which unites the arteries of each side with one another. The situation of this branch is just at the junction of the cervix and body. During pregnancy other anastomotic branches are developed.* As the preg- nant uterus is situated directly under the abdominal Avails, the arterial murmurs are at certain points distinctly appreciable, and furnish the auscultatory sign of pregnancy improperly termed the "placental * Hyrtl disputes the formation of anastomoses during pregnancy, and states that in the pregnant as well as in the non-pregnant uterus none but capillary com- munication exists between the arteries.

The origin of this artery is situated about two and a half inches above the bifurcation of the aorta. It pursues a serpentine course, and, in places, makes spiral turns, which are specially marked during preg- nancy. It descends obliquely downward under the peritonaeum to the cavity of the pelvis, and then ascends between the folds of the broad ligaments to reach, by its branches, the ovary, the Fallopian tube, and, by its main trunk, the side of the uterus, where it forms a direct communication with the art. uter- ina hypogastrica. This communication between the aortic and hypogastric uterine arteries serves to maintain a con- tinuous blood current during ges- tation. The situation of the uter- ine artery within the pelvic cavity, and its exposure to pressure, would render it, were it the sole source of blood-supply, an extremely unsafe dependence. It is well to note here, that when pressure is made upon the aorta, after childbirth, with a view to checking posf-par- tum haemorrhage, the manipulation fails to affect in any way the blood- stream which pours into the uterus from the aortic uterine branches. The beautiful injections of Rouget* have demonstrated a pe- culiar disposition of the aortic uter- ine branches, as they penetrate the body of the uterus. Instead of di- viding, as they branch, dichoto- mously, they break up, on reaching the vicinity of the Fallopian tubes, into from twelve to eighteen arterial tufts, of which each branch is twisted in spiral form. These tufts of vessels are so aggregated to- gether as frequently to cover the angles of the uterus. The veins of the uterus form a net-work, which traverses the uter- ine tissues in all directions. As their walls are intimately adherent to the muscular tissues of the uterus, they remain ]iatulous upon section, and, when enlarged by pregnancy, are termed " sinuses.-" Rouget like- wise describes twisted, tangled venous tufts, which often form spirals * Rouget, Eecherches sur les Organes firectiles de la Femrne, Jour, de la Physiol., 1858, t. i, jip. 320 et seq.

Tlie same authority claims that the ultimate divisions of the arteries communicate with the venous sinuses by very line vessels, measuring from ^o^th to -^^th of an inch, instead of by capillary net- works. The return-currents of the uterus empty into two venous plexuses : 1. The plexus uterinus. This plexus receives its blood from the uterus alone. It extends between the folds of the broad ligament, and empties into the hypogastric vein. 2. The plexus pci'iipi'iifonuis. The plexus pampiniformis derives its blood from the uterus, the Fallopian tubes, and ovaries. Its vessels combine to form a single trunk, the vena spermatica interna, which follows the course of the artery of the same name, and empties, on the left side, into the vena renalis, on the right into the vena cava.

The arterial branches anastomose within the ovary, and form an interlacement, including spaces, which become smaller and smaller as the surface of the gland is approached. The veins start as radicles from the capillaries, then rapidly enlarge, and present a varicose appearance. By their anasto- moses they form a plexus, which includes spaces of very irregular size. The blood is then taken up by venous trunks, which run parallel to the arterial branches, and terminate finally in the internal spermatic vein (termed by Sappey, Fig. 18, the utero-ovarian vein). Upon the basis of the foregoing description * Rouget draws a par- allel between the structures of the penis and those of the corpus uteri, and claims identity between the two organs. One feature, however, of « * Rouget, Recherches sur les Organes ^firectiles de la Pemrae, Jour, de la Physiol., t. 1, pp. 338 et seq. 2g PHYSIOLOGICAL ANATOMY. the erectile tissue, as generally understood, is wanting in the uterus, viz a dense, fibrous sheath, a tunica albuginea, inclosing the erectile or^rln limiting the degree of its distention and enhancing its turgidity "as experimental proof that the uterus possesses erectile properties, Eou-et has shown that, when an injection is forced by the spermatic arter^y, in the dead subject, so as completely to distend the vessels of the body of the uterus, the latter becomes elevated in the pelvis, and makes a movement similar to that performed by the penis during venereal excitement. It is, however, obvious that the forcible distention of the vessels of a flaccid uterus, in which the muscular walls are deprived of their normal tonus by death, does not necessarily represent the phenomena produced during life by the turgescence resulting from either ovula- tion or the sexual orgasm. Unfortunately, so far as the body of the uterus is concerned, the difficultiss in the way of direct observation upon the living subject have hitherto rendered the settlement of this point impossible. With regard to the cervix uteri, we have physiological as well as anatomical reasons for admitting a certain kind of erectility. To be sure, a tunica albuginea is wanting. It is, therefore, not an ideal erect- tile oro-an. But it is among the occasional unpleasant exijeriences of gynecological practice that a simple digital examination, made for the purpose of a diagnosis, may evoke the venereal orgasm. Precise observations as to the phenomena presented by the accessible portion of the uterus during the orgasm have been furnished by Wernich,* Litzmann,f and in one remarkable case by Beck, \ which leave very little doubt that strong erotic excitement is attended by a rigidity of the cervix, which produces an impression upon the fingers similar to that imparted by the glans of the male organ during erection. The following anatomical peculiarities of the cervix uteri are fur- nished by Henle : The walls of the vessels (arteries, capillary branches, and veins) are characterized by an extraordinary development of the circular layer of muscular fibers. For instance, in vessels measuring from -gxro" ^^ To7 of an inch, the diameter of the bore is scarcely one third the diameter of the entire vessel. The arrangement of the ves- sels is likewise peculiar. In the labia uterina, especially within the muscular tissues, small branches pass directly down to the mucous sur- face. These branches pursue an undulatory course, are parallel-, and run at nearly equal distances from one another. Just beneath the mucous surface in like manner the veins arise and make their way up- ward parallel to the arteries, and with the same orderly arrangement. * Werxich, Die Erectionsfahigkeit des unteren Uterus- Abschnittes, Beitr. zur Geburtsh. und Gynaek., Bd. i, p. 296. f Wagner s Handworterbuch der Physiologie, Bd. iii, p. .53. X Beck, How do the Spermatozoa enter the Uterus? Am. Jour. Obst., Nov., 1874. FEMALE ORGANS OF GENERATION. 27 The capillary connections between these veins and arteries are situated just beneath the epithelium, where they form looped projections into the papilhv. In the pliciv palinata^ the general direction of the vessels is likewise perpendicular to the surface. In commenting upon these facts, Ilenle remarks that there is nothing in the situation of- the arterial walls that would call for their special development, as they are not ])articularly exposed to external pressure. " Where, liowever," he says, " extraordinary means are employed in maintaining contraction, extraordinary relaxation and dilatation are possible." He therefore premises, as at least probable, " that the changing degrees of contrac- tility in the finer vessels may serve to impart a sort of capacity for erection, or, at least, turgescence, to the cervical and vaginal portion " — an anatomical deduction sustained, as we have seen, by physiological observation. A similar atteiii])t on the part of M. Rouget to constitute an erect- ile organ out of the ovai-y is disposed of by Sappey as follows : " Erectile tissue is formed by large, short, anastomosing capillaries, supporting muscular trabecula?, and into which open the ultimate divisions of the arteries; but in the bulb (the vascular portion of the ovary) there are neither dilated capillaries, nor areolae, nor trabeculse. The analogy signalized l)y M. Rouget is thei-efore much more apparent than real."' ^ The Nerves. — The nerves of the uterus are derived from the gan- gliated cords of the sympathetic system, through which important connections are formed with all the abdominal viscera. Just at the bifurcation of the aorta there is a broad band of nerve tissue termed the plexus uferinvs magnus, formed by the coalescence of filaments from the spermatic ganglia (two i^airs of ganglia, situated upon each side of the inferior mesenteric artery) and filaments derived from that ]iortion of the aortic plexus which is distributed mainly to the supe- rior mesenteric artery (plexus mesentericus superior, Frankenhaeuser).f About an inch and a half below the bifurcation of the aorta it divides into two strands, the plexnf< Jn/pof/asfrici, which pass right and left around the rectum to the uterus and upper portion of the vagina. The hypogastric plexuses receive nerve branches from the lower lum- bar and three upper sacral ganglia. Upon the sides of the rectum they divide each into two jiortions, of which the smaller passes directly to the posterior and lateral w^alls of the uterus, while the larger con- tributes to the formation of the cervical ganglion. The cervical ganglion (Frankenhaeuser) is not, according to Jastre- botf,;|: a separate organ, but a large plexus comi:>osed of many ganglia, * Traite d'Anatomie.

In the niusenlar tissue of the uterus, lymph-spaces are found in the deli- cate connective tissue which unites the muscular bundles together. Regular lymphatic veissels are found in the con- nective tissue which accompanies the arterial trunks into the uterine paren- chyma. A net-work of lymphatic ves- .sels, with dilated and constricted por- tions, and provided with valves, exists beneath the serous coat. The lymph- .-paces of the uterine mucous mem- l)rane communicate, by funnel-shaped depressions, with the lymph-spaces and lymphatics of the muscular strata. Just beneath the external muscular layer, upon the lateral borders of the uterus, are large receiving vessels, into which empty the lymphatics from both the subserous and uterine vessels. The lymphatics of the cervix pass to the glands of the pelvic cavity, while those of the border and fundus follow the course of the plexus pampiniformis to form connections with the lymphatics of the lumbar region.* Deyelopmext of the Female Generative Organs. — Three con- nected structures make their ap- pearance on either side of the spinal column, at an early period of fetal existence, which need to be under- stood by those who would gain a clear idea of the developed organs of generation in the female. These structures are the Wolffian bodies, the ducts of j\[uller, and the rudi- mentary organs Avhich are destined at a more advanced period to be- come the ovaries. The Wolffian bodies are oblong glandular structures, temporary in character, which are thought to perform, in the embryo, the excretory function of the kidney.

Two organs, destined to become the orarics, make their appearance upon the iliner side of the Wolffian bodies. They possess at first an elongated, but subsequently assume a more oval appearance. The ducts of Miiller are secondary formations, and are produced by an inversion of the peritoneal epithelium, beginning near the anterior end of the Wolffian body and thence extending downward parallel to the Wolffian ducts. (Kolliker.) Below they pass spirally forward, where they meet in the median line, to descend together to the sinus Fig. 23.— Uterus unicornis from a young child, posterior asi>ect (Pole), o. uterus unicornis, left half of uterus undeveloped ; 6, right Fallopian tube ; c, left Fallopian tube, exceptionally present ; d, d, ovaries ; e, bladder.

The free portions of the filaments become the Fallopian tubes. Both uterus and vagina are at first divided into two parts by a common partition-wall, which disap- pears subsequently from below upward. Bayer (Freund's Gynakolische Klinik, Bd. i, p. 412 et seq.) regards the uterus as derived not alone from the ducts of Mllller, but that tlie retractors, the round ligaments, and the ovarian ligaments likewise contribute to the forma- tion of its muscular structures. In the Fallopian tubes there are tlnee layers of muscular tissue, viz., the external and internal longitudinal layers and the median layer, whose fibers run in a transverse direction. The fusion of the tubes forms, as it were, the frame upon which the uterus is built. From the external and internal longitudinal fibers are derived the longitudinal fibers of the outer and inner layers of the uterus. The spirals, which aae observable at the uterine cornua, are formed from the longitudinal fibers by a semirotation of the tubes from before backward at their point of union Avith the uterus. The transverse fibers in the median layer oi the tubes persist as circular fibers in the uterus. The retractor muscles pass to the lower portion of the cervix, are thence reflected upward, and their fibers cross at the level of the internal os. FEMALE ORGANS OF GENERATION. 31 At each point in their course they give off fibers to the substance of the uterus and contribute the principal share to the median layer of the lower uterine pole and of the cervix, forming an interlacement with the other muscular bundles. The chief mass of the posterior wall of the body, and of the layers surrounding the cornua, are derived from the ovarian ligaments, while the outer layer of the anterior wall of the corpus, of the lower portion of the cervix, and the entire supravaginal portion are derivative from the round ligaments. The median layer of the fundus is composed of fibers derived from both the round and ova- rian ligaments. The uterus, at the fourth month of fetal life, presents distinct traces of the early origin from the ducts of Miiller. The fundus is undevel- Fig. 23.— Double uterus and vagina from a girl aged nineteen (Eisenmann). a, double vaginal orifice with double hymen ; 6, meatus urethras ; c. clitoris ; d, urethra ; e, e, the double vagina : /, /, uterine orifices ; g, r/, cervical portions ; h, h, bodies and cornua ; i, i, ovaries ; k, k.

Two eornua, or horns, are thus distinguishable upon the external surface of the uterus. About the eighth or ninth month the convex fundus is developed, and the eornua disappear externally, though all through life they are traceable upon the inner surface in lateral sec- tions of the uterus (ride Fig. 15, p. 21). Before the differentiation of sex has taken place, the external organs of generation present the following appearances : Two ridges, or folds, surround a central opening (sinus uro-genitalis), which either unite to form the scrotum of the male, or develop into the labia majora in the female. Where these folds join together above, there is a small pro- jecting body, or tubercle, destined to become the penis or the clitoris. In either case the lower surface of the tubercle is furnished with a groove. The margins of the groove extend along the sides of the sinus uro-genitalis, and, in the development of the female type, become the FiQ. 26.— uterus septus bilocularis.

Abnormalities of the Uterus. — An arrest of fetal development gives rise to a number of deviations from the ordinary uterine type, of 3 34 PHYSIOLOGICAL ANATOMY. which we borrow from Courty the following as of direct obstetrical im- portance : 1. Uterus Unicornis.— The one-horned uterus results from the atro- phy or incomplete development of one of the filaments of Miiller, while the other continues its evolution. We then have a uterus which is com- posed of a single lateral half, possessing generally but one Fallopian tube. 2. Uterus Duplex, or Didelphys. — Both filaments of Miiller are de- veloped, but do not become united together. Thus two distinct uteri are produced, of which each represents in reality the half of a normal uterus. 3. Uterus Bicornis. — Partial union of the filaments of Miiller takes place, but without reaching the ordinary level indicated by the inser- tions of the round ligaments. The upper portion of the uterus is thus divided into two horns, separated by a furrow from one another. 4. Uterus Cordiformis. — The uterus remains of the fetal type indi- cated in Fig. 25. Instead of a complete development of the fundus, the latter remains depressed, and presents an appearance remotely re- sembling the heart of a playing-card. 5. Uterus Septus Bilocularis. — Complete union of the two filaments of Miiller has taken place, but the common wall, formed by their co- alescence, persists. We have thus two distinct uterine cavities. The septum may extend the whole length of the vagina, and give rise to a double vagina ; or absorption of the vaginal septum and a portion of the uterine septum may have taken place, so that we may have a double uterine cavity with a single cervix, vfrrns semi-partitus.

The following account of the history of the ovum is derived in great measure from Waldeyer.* The GKAAFI.A.N" Fol- licles AND THE Ovum. — In the embryo of the chick, by the fourth day of incu- bation, the Wolffian body is covered by cylindrical epithelium, contrasting sharply with the flattened cells of the peritonaeum. Soon after, a thickening of the epithelium becomes noticeable on the inner side, and forms the earliest trace Fig. 28.— Section of Wolffian body, with rudimentary ovary (embryo of chick, fourth day of incubation).

The epithelium is destined to form the Graafian follicles and ova; the proliferated connective tissue furnishes the vascular stroma of the ovary. Between the fourth and fifth day certain cells already indicate their destiny as future ova by their size, their rounded shape, and large nuclei. The further develop- ment of the ovary is the result of the multiplication of the epi- thelial cells and the continued growth of the stroma. As the connective-tissue processes grow outward and penetrate between the cells, the latter gradually be- come imbedded in the stroma. Thus, the connective-tissue pro- cesses assume a trabecular ar- rangement, the meshes of which are filled with cell-masses of a nearly cylindrical shape, which hang together in the form of a net-work. Among the imbedded cells, the large ones already no- ticed are termed "primordial ova." The smaller cells remain small, and arrange themselves like epithelium around the larger ones. In the course of develop- ment, the interpenetration of the connective tissue continues, until each primordial ovum is con- tained in its own separate par- tition. These partitions, with the included cells, are rudiment- ary Graafian follicles. Two dis- tinct ova within the same Graafian follicle are of rare occurrence. As the ova enlarge and the epithelial cells multiply, an irritative action is set up in the surrounding stroma. An increase in vascularity re- sults, and young connective tissue is developed about each epithelial collection. As the follicle grows, the outer layer becomes fibrillated. Thus around each Graafian follicle a distinct .envelope is formed, termed by Baer the tJieca folUcuU, consisting of an internal vascular coat, the tunica propria, and an external fibrillated coat, the tunica fibrosa. Each primordial ovum is at first encircled by a single layer of cylin* Fia. . 29.— Section through portion of the ovary of mammal, illustrating mode of develop- ment of the Graafian follicles ( Wiedersheim).

Gradually new layers form, in which the ovum lies im- bedded. Afterward, at a point remote from the ovum, a crescent- shaped opening makes its appearance, which becomes filled with a clear fluid derived from transuded serum, and in part from liquefied epithe- lium. A heap of cells remains about the ovum and forms the discus proligerus.

A glance at a transverse section through the ovary of a mature mam- mal exhibits follicles of different ages. To recapitulate : 3g PHYSIOLOGY OF THE OVUM, The young follicles are composed of primordial ova, surrounded by epithelium, and imbedded in the ovarian stroma. The fully developed follicles possess a vesicular character. They are surrounded by a connective-tissue wall (theca folliculi), which is composed of two layers (tunica propria and tunica fibrosa). The tunica propria is lined by cells (membrana granulosa), which are gathered in heaps (discus proligerus) around the ova. The discus proligerus is seated sometimes superficially, sometimes in the deepest portion of the follicle. Each ovum is surrounded by a special layer of cylindrical epithelium (epithelium of the ovum). Henle estimates the entire number of Graafian follicles in each ovary at thirty-six thousand. The primordial ova, we have seen, consisted originally of epithelial cells distinguished by their rounded shape and large nuclei. For a cer- tain period these cells have a continuous growth, due probably to the absorption of nutritive material furnished by the liquefaction of cells in the discus proligerus. The nutrient material, according to Nagel,* is derived from special cells containing nuclei and one or more nucleoli, and of larger size than the ordinary follicular epithelium. The liquefied product, Nagel maintains, enters the protoplasm of the primitive ova by diffusion. The fully developed ovum is no longer a simple cell composed of pro- toplasm. It is of large size. In the human female the ovum measures about yfg- of an inch in diameter. As it lies in the discus proligerus it is surrounded by elongated cells with distinct nuclei and finely granu- lar protoplasm. These cells are placed side by side, and are arranged in two to three layers. By Waldeyer they have been termed the epithe- lium of the ovary, and by Bischoff, owing to their characteristic appear- ance, the zona radiata. The mature ovum possesses a thick, transparent envelope, termed the vitelline membrane or, from the manner in which it transmits light, the zona pellucida. The zona pellucida was formerly thought to be due to a thickening of the cell contour. It is now commonly regarded as something superadded to the primordial ovum. Probably the at- tached portions of the radiate cells contribute to its formation. It has been noticed as a curious coincidence, that at the time of the appear- ance of the zona pellucida a similar clear, structureless membrane de- velops between the membrana granulosa and the internal layer of the theca folliculi. When the zona has once formed around the ovum the latter ceases to increase in size. The ovum and the zona are not in immediate contact. Between the two there exists a clear space, termed the perivitelline space, which * W. Nagel, Das Menschliche Ei, Arch, fur Microscopische Anatomic, vol. xxxi, pp. 380 and 381.

DEVELOPMENT OF THE OVUM. 39 permits amwboid movement and rotation of the egg protoplasm to take place. The thickness of the zona is from one twentieth to one tenth the diameter of the ovum. The body of the cell, which constitutes the primordial ovum, be- comes the vitellus of the ripe egg. It possesses contractility and other properties of protoplasm. In the mature ovum it assumes an opaque appearance, due to the development of granular matter and light-re- fracting particles. The primitive cell matter of the vitellus is termed the protoplasm of the ovum, or the formative yelk. From it are de- rived the cells which furnish the basis of embryonic development. The small particles consist of nutrient material, and are termed deutoplasm, or the 7iutritive yelk, as they constitute at an early period the material which contributes to the cell growth. The deutoplasm is supposed to be derived from the liquefied cells of the discus proligerus, but in the human ovum the penetration of particles from without is not direct. They do not appear until after the zona is formed, when the growth of the ovum ceases. They therefore are to be regarded as the product of the vital activity of the cell. Upon the addition of eosin the protoplasm is colored with a beautiful rose tint, while not a trace of the coloring matter is taken up by the deutoplasm (Nagel). The particles first make their appearance at the center of the vitellus. In the perfectly fresii human ovum it is possible to distinguish a central portion rendered opaque by deutoplasm, a finely granular ring in which the protoplasm predominates, and a clear peripheral border in which the protoplasm is free from deutoplasmic matter. The nucleus of the cell becomes converted into a large, clear, color- less vesicle, known as the germinative vesicle. It occupies an eccen- tric position in the clear outer zone of the vitellus. The nucleolus per- sists as a dark, probably solid body within the germinative vesicle. It is characterized by amoeboid changes of shape, and is termed the germi- native spot. Discharge of the Ova from the Ovary, and the Formation OF the Corpus Luteum. — We have already seen that the number of Graafian follicles within a single ovary is estimated at many thousands. The formation of these follicles is, in great degree at least, completed during the antenatal period of existence. Previous to puberty, how- ever, they remain in a quiescent condition. With the advent of puberty the ovaries assume functional importance. The surface of the ovary, if examined at this time, is no longer smooth, but studded with small vesicles. These vesicles are nothing more than the enlarged Graafian follicles, which, as they become distended by their fluid con- tents, approach the periphery, thin the tunica albuginea, and form rounded translucent prominences. By the additional disappearance of the blood-vessels and the lymphatics, a weak point in the wall of the follicle, the macula or stigma folUcuU, is left exposed. ^Q PHYSIOLOGY OF THE OVUM. The discharge of the ovum is closely associated with the formation of the corpus luteum. The corpus luteum begins by an abundant cell proliferation, in which both the follicular epithelium and the tunica propria participate. This cell proliferation is most abundant at the bottom of the Graafian fol- licle. Vascular arches push forth into the cavity, and still further en- croach upon the already crowded space. Finally, a point is reached at which the follicle ruptures, and its contents, including the ovum, are discharged. When the Graafian follicle has reached maturity, the con- gestion, occurring at the time of the menses, operates unquestionably in a most effective manner to the accomplishment of this result. Immediately following the rupture of the Graafian follicle, blood is effused into its cavity. At the same time a process of cell disintegra- tion ensues. But, in place of a degenerative product, the disintegra- tion furnishes a granular, vitellus-like substance of a yellow color. Ex- amined by the microscope, in addition to the granular mass, globules may be recognized, which correspond to the light-refracting particles contained in the vitellus of the ovum. While the above-mentioned process is going on, an abundant trans- migration of wandering cells (lutein cells, Nagel) from the vascular network surrounding the follicle takes place, which lift up the granu- losa cells, with the pseudo-yelk substance, and press them toward the center of the follicle. Along with the young wandering cells, vascular offshoots, like small papilla?, push out from every side into the epithe- lial and vitellus-like masses. As the larger vessels form more marked projections, they give to the corpus luteum a folded appearance. In a state of complete development the corpus luteum consists of — 1. The pseudo-yelk substance, mingled Avith effused blood. 2. The thickened layer of the granulosa and lutein cells, mingled with yelk- substance. It is this layer which, to a great extent, forms the folded, yellow portion of the corpus luteum. 3. The vessels which, 'with the lutein cells, push from all directions into the epithelial masses. As these vessels reach the center of the follicle, a complete interpenetra- tion of the connective tissue and epithelial elements of the corpus luteum results, and the foldings become indistinct. Finally, absorption of the vitellus-like substance occurs; the last vestiges of the effused blood are converted into blood-crystals ; the arte- rial vessels degenerate ; the epithelial masses and the connective-tissue mesh-works disappear gradually, until at the last only a white, stellate cicatrix remains. If the ovum is discharged without impregnation taking place, the corpus luteum reaches its maximum size at the end of three weeks, and then begins to decline, until, at the end of two months, it is reduced to an insignificant cicatrix. But when conception occurs, the changes in the corpus luteum take place more slowly. The corpus luteum reaches DEVELOPMENT OP THE OVUM. ^i a higher state of development. Its increase in size continues for two months. It then remains stationary up to the end of the sixth month. During the hist three months of pregnancy it gradually loses its bright- yellow color, grows smaller, but still measures one half of an inch in diameter at the end of the period of gestation. The corpus luteum of pregnancy is often termed the true corpus luteum, to distinguish it from the more trivial variety which is pro- duced by the rupture of a Graafian follicle at a menstrual period, or between two menstrual epochs. The latter has been termed the false corpus luteum, because it is found in virgins, and does not constitute a sign of pre-existent pregnancy. The Migration of the Ovum.— The number of ova in each ovary amounts to many thousands. Only a small proportion of them, how- ever, meet with the conditions requisite for fruition. It is probable that many ova perish while still surrounded by the stroma of the ovary. It becomes an interesting subject of inquiry as to the conditions which ordinarily determine the passage of the ovum from the ovary into the Fallopian tube of the corresponding side. It will not do to assume, as is usual, a peculiar erectility of the Fallopian tube, which enables it to apply its funnel-shaped extremity to the ovary just at the moment of the rupture of the Graafian follicle. Setting aside the inherent im- probability of the existence of such a degree of intelligence in the fim- briae as would lead to the exact adaptation of the tube to the precise point at which the ovum is to be discharged, it has been proved that the Fallopian tube possesses none of the characteristics of erectile tis- sue. Injections of its vessels after death do not communicate to it the slightest change of form or place.* Muscular action has also been often invoked to explain the assumed manner in which the fimbriae seize the ovary, but galvanization of the tubes, practiced upon criminals recently executed, produces only ver- micular contractions, which do not affect the position of the fimbrije.f Indeed, when we remember the position of the Fallopian tubes in the pelvis, and bear in mind that they are at all times necessarily subjected to the pressure of the intestines, it becomes difficult to understand how they can execute any very extended movements. | * RouGET, Les Organes ftrectiles de la Feinme, Jour, de la Physiol., t. i, 1858, p. 337. f Hyrtl, Handbuch der topographischen Anatomie, Wien, 1865, Bd. ii, p. 210. i Henle, Handbuch der Eingeweidelehre, Braunschweig, 1866, p. 470. Rouget (vide Organes firectiles. Jour, de la Physiol., 1858) has studied with great care the arrangement of the muscular fibers situated between the peritoneal layers of the broad ligament. These fibers are directly continuous with the delicate external muscular layer of the uterus. Certain of them are so distributed, according to Rouget, as to produce by their contraction a direct approximation of the fimbria; to the ovary. Henle remarks, by way of criticism, that more stress might be laid upon tbase fibers were they distributed to the Fallopian tubes alone. As, however, they ^2 PHYSIOLOGY OF THE OVUM. In the absence of dii-ect experimental proof, the suggestion oi Henle that the passage of the ovum into the Fallopian tube is due to the currents produced in the serum by the ciliated epithelium, which covers both the external and internal surfaces of the fimbriae, is, on the score of probability, entitled to the most consideration. One of the fimbriae (fimbria ovarica. Fig. 13) is, as we have already seen, per- manently attached to the lower angle of the ovary. It is likely that the ovum, discharged from a Graafian follicle, is floated down by the peritoneal serum toward the lower and outer border of the ovary, where a sufficient current is present to insure its being caught up and con- veyed into the infundibulum tuba?. Failures on the part of the ovum to reach its destination are, in all probability, not uncommon. Support is given to the theory of the importance of the cili* in influencing the migration of the ovum by the observation of Thiry,* that in batrachi- ans, which have the oviducts fixed to the abdominal walls, and situated at a distance from the ovary, during the rutting period little pathways of ciliated epithelium form in the peritonaeum, which collectively con- verge toward the openings of the tubes. Cases of the complete migration of the ovum from the ovary of one side to the Fallopian tube of the opposite side are not readily explained by any hypothesis. 'Yet the occurrence of such cases is undoubted. Pregnancy, for instance, may exist where there is complete absence or closure of the Fallopian tube upon the same side with the corpus luteum. Leopold tied the right Fallopian tube in rabbits in two places, and exsected a portion of the tube between the ligatures ; the left ovary was carefully removed and the abdominal wound was closed. After recovery the rabbit was put to the male. In two such cases pregnancy followed, f The progression of the ovum through the Fallopian tube is effected by the ciirrent produced by the ciliated epithelium and by the peristal- tic action of the circular muscular fibers. Fecundation. — The precise point at which fecundation takes place has been variously assigned by authors to the tubes, the uterus, and the ovary. The question, however, up to the present time is a purely speculative one. The length of time required by the human ovum to complete the passage from the ovary to the uterine cavity is unknown ; nor has as yet the period of the extra-ovarian life of the ovum, when not vivified by the contact of the male element of generation, been de- termined. Single observations show that fecundation may take place in any part of the course described. The ordinary site of fecundation is a matter which remains to be decided by future investigations. spread likewise over the ovary, their probable action would consist in drawing both ovary and tube toward the median line. * Thiry, Gottingen Nachrichten, 1862, p. 171. f Arch. f. Gynaek., vol. xvi, p. 24. DEVELOPMENT OF THE OVUM. 43 Fig. 31. — Spermatozoa from the human subject (magnified eight hundred diameters). (Luschka.) The seme}i, contact with which is essential to the fecundation of the ovum, is a tliick, viscid, albuminous fluid, of a whitish color and a peculiar odoi-, which has been compared to that of the raspings of bone. When examined by the microscope, it is found to contain numerous minute anatomical elements, termed spermatozoa. Each spermato- zoon consists of an oval head and a long filiform extremity or tail. The head is flattened, and measures about ^nsW of an inch in width. When seen in pro- file, it presents a pyriform appearance. The entire spermatozoon measures from ^oTT ^o T^ ^^ ^^ inch in length. The spermatozoa do not simply float in the seminal fluid, but possess the capacity of moving from place to place, as though endowed with volition. In- deed, as the observer sees them advance, now singly and now in shoals, now diving down and then rising again to the surface, now avoiding some obstacle, or skillfully picking their way between masses of epi- thelium, it is difficult to resist the conviction that they are really, what they were long supposed to be, distinct organisms capable of a certain degree of voluntary action. But there is little doubt, at the present day, that the undulatory movements of the tail, which furnish the pro- pelling force, are due to purely molecular tissue changes, similar to those which give rise to the amoeboid movements of protoplasm or the oscillations of the hair-like processes of ciliated epithelium. Henle estimates that the spermatozoa travel at the rate of an inch in seven and a half minutes. It is to these bodies that the semen owes its fecundating power, but only so long as they retain the faculty of motion — a faculty which has been found to exist in full force, within the female genital organs, eight to ten days after ejaculation.* In 1840 Martin Barry described a point in the zona pellucida (vitel- line membrane) of the rabbit, which appeared to him to be an opening designed for the passage of spermatozoa. At first embryologists pro- nounced Barry's descriptions to be based upon an illusion, but since then the existence of such an opening, termed later by Keber the mi- cropyle, has been abundantly demonstrated in the ova of fishes, mol- lusks, insects, etc.f A very interesting series of observations connected with this sub- ject have been made by M. Kobin upon the ova of the nephelis vul- garis, or common leech. The earliest token of the maturity of the * Luschka, Die Anatomie des menschlichen Beckens, Tubingen, 1864, p. 273. t Vide Milne-Edwards, Legons de la Physiologie, t. viii, Paris, 1873, pp. 361 et seq. ; Waldeyer, Eierstock und Nebeneierstock, Stricker's Handbuch, p. 354. 4:4 PHYSIOLOGY OF THE OVUM. ovum consisted in the disappearance of the germinative vesicle. At the same time a retraction took place in the vitellus, which became thereby reduced one sixth to one fourth in size. At first the removal of inter- nal pressure, consequent upon this retraction, led to a wrinkling of the vitelline membrane. Afterward, however, a clear, limpid fluid, proba- bly in part exuded from the vitellus and in part derived by endosmosis from external sources, filled up the intervening space, and caused the wrinkles to disappear. The spermatozoa, in their movements around the ovum, assumed a perpendicular or oblique direction to the vitelline membrane. At one point in the membrane the penetration of these bodies could be distinctly observed. At the end of an hour the penetra- tion had ceased, and then a little bundle of spermatozoa could be seen arrested, partly within and partly without the ovum. In the clear, limpid space surrounding the vitel- lus, the spermatozoa continued to move about actively for a time, but in fifteen to twenty minutes their movements began to grow slow, and in a couple of hours had ended altogether.* In the human ovum nothing in the nature of a micropyle has been observed. The fine radiate lines which may be seen in the zona pellucida when high magnifying powers are employed do indeed suggest the idea of minute pores, but the view of Waldeyer f has been generally accepted, that these are really unchanged filaments of protoplasm derived from the cells to which the zona pellucida owes its origin.

In describing its anatomy, we have noted that the ovum was orig- inally a simple cell, possessing contractility and other properties of liv- ing matter. The ova of certain of the sponges, which do not possess a zona pellucida, move about under the field of the microscope by pushing out finger-like processes, precisely like the ordinary amoeba.J Contractile movements of the vitellus within the zona pellucida have * Memoire sur les Phenoraenes qui se passent dans I'Ovule avant la Segmenta- tion du Vitellus, Robin, Jour, de la Physiol., t. v, pp. 67 et seq. \ Waldeyer, Eierstock und Nebeneierstock, Strickee's Handbuch der Lehre von den Geweben, Leipsic, 1871, p. 354.

DEVELOPMENT OF THE OVUM. 45 been described by Robin in the ova of the leech and other low orders of animal life.* With the formation of the deutoplasm the germinative vesicle is crowded to the periphery of the ovum. The maturity of the ovum is signalized by the detachment from the main mass of two small cells termed the polar globules. Formerly this process was supposed to be associated with the disappearance of the germinal vesicle. More recent investigations have demonstrated that in the production of the polar globules the germinative vesicle plays an active part. Thus observation shows that the latter elongates in a radiate direction. Around the two extremities, or poles, nuclear matter from the vitellus collects. A separation of the lines connectino- the poles next takes place, and two new nuclei surrounded by radiate masses of yelk matter result. These liave a star-like arrangement. The upper pole is then extruded and the first polar globule is formed. The process is then repeated, and the second polar globule is perfected. Finally the persistent portion of the original nucleus recedes from the surface. It resembles in appearance the original germinal vesicle with its nucleolus, and is known as i\\& female pronucleus. The formation of the polar globules is a sign that the ovum has reached maturity, and occurs independently of fecundation. The latter is effected by the penetration into the vitellus of a single spermatozoon, the head of which is termed the )nale pronudeus. The male pro- nucleus approaches the female pronucleus, and the two coalesce to form the segmentation nucleus of the fecundated ovum. After this union has taken place the ovum is turmed the oosperm.

Almost immediately after the production of the segmentation nucleus it divides into two nuclei. By a similar process of cleavage the vitellus likewise divides into two halves. The nuclei act as central points, around which collect the molecular and viscid portions of the pro- toplasm. In this manner the ovum is divided into two new cells, which differ somewhat in size, and which lie near together within the zona * Haeckel, Anthropogenie, Leipsic, 1874, pp. 100 et aeq. 4:6 PHYSIOLOGY OP THE OVUM. pellucida. The larger cell and tliose subsequently derived from it are termed the epiblastic spheres, and the smaller one with its products are termed hypoblastic spheres. To the cleavage process by which the single cell has been converted into two, the term segmentation is applied. By continued segmentation the two cells are divided into four, the four into eight, and so in succession, until finally a great Fig. 34.— Formation of the blastodermic vesicle (Van Beneden).

"When the segmentation process is completed, the epiblast cells occupy the outer circumference and line the inner surface of the zona pellucida, except at one point, termed by Van Beneden the blastophore. They are clear, and have an irregular cubical form. The hypoblast cells form a solid mass in the center. They are granular, polygonal, and are somewhat larger than the epiblast cells. The epiblast cells next grow over the blastophore.

By an increase of the fluid the morula is converted into a globular vesicle, termed the blastodermic vesicle. The hypoblast cells are pressed to the circumference, where they form a lens-shaped mass attached to the epiblast cells and projecting into the cavity of the vesicle. The blastodermic vesicle continues to enlarge rapidly. The hypoblast cells be- come flattened and spread over the inner sur- face of the epiblast. The central part thick- ens and forms a dark spot, which constitutes the commencement of the embryonic area; upon sec- tion, the embryonic area is found to consist of three lay- ers, the outer layer composed of epi- blast cells, and two inner layers com- posed of hypoblast cells. The former takes no active part in the formation of the embryo, but disappears at an early period. Beyond the embryonic area the epiblast cells help to form the amnion. The hypoblast cells alone contribute to the formation of the new being. The outer layer becomes the epiblast, and the inner layer forms the hypoblast of the embryo. Sub- sequently a third intermediate cell layer, termed the mesoblast, develops between the embryonic epiblast and hypoblast. At a later period the cells of the mesoblast and of the hypoblast spread by peripheral extension, and finally line the inner surface of the primitive epiblast.* Without entering minutely into the subject, it may be well to state that, according to present views, the three layers existing at the em- * This description is taken from Van Beneden's Developperaent Embryonnaire des Mamraiferes, Bull, de I'Acad.

The hypoblast furnishes the epithelium lining the walls and glands of the intestines, and the epi- thelium of the lungs and of the air passages. The mesoblast gives rise to the corium, the muscles of the trunk, the bony framework, the connective tissues, the muscular structures of the digestive tracts, the blood, the blood-vessels, and the genito-urinary system.* The first change observed in the embryonic area consists in the appearance of a dark streak, the primitive streak, due to a thickening of the mesoblast. It becomes grooved, and is known as the primitive groove. It has nothing to do with the development of the embryo. The embryonic area, which was pre- viously of a rounded form, now assumes an ovoid shape.

The chorda dorsal is owes its importance to the fact that it is around this cylindrical body that the vertebra subsequently form. Tlie vertebrae themselves are derived from two longitudi- nal chords, separated by a cleav- age from the portions of the in- termediate layer next to either side of the chorda dorsalis. The peripheral portions of the inter- mediate layer are now termed the lateral or abdominal plates.

Tims it Avill be noticed that the organ through the agency of which the individual is brought into contact with the external world is primitively derived from the epiblastic layer. The intermediate layer (mesoblast) now separates into an internal and external stratum, the existence of which, it has been noted, was indicated at an earlier stage. These two strata remain united by their inner borders, and form later, at the point of union, the mesenteric folds. The outer extremities of the inner of these strata now curve inward, and finally unite together to form the intestine. They inclose at the same time the hypoblast. The closure, unlike that of the dorsal plates, takes place from front to rear, as well as from the two sides. The intestinal tube is thus formed from the inner stratum of the mesoblast, which furnishes the fibro-muscular tissues, and from the hypoblast, from which the glandular structures are derived. A por- tion of the blastodermic vesicle is, however, not included in the in- testinal tube, but hangs, during the early months of gestation, from the body of the embryo, and is termed the umhilical vesicle {u v). Finally, the epiblast and the- outer stratum of the mesoblast (the fibro- muscular layer of the trunk) curve forward and inward so as tc inclose a long cavity which surrounds the intestine. This cavity in mammals subsequently becomes divided by the diaphragm into thorax and abdomen. The body of the embryo, seen in profile, at the time these changes are going on, possesses a thickened anterior or cephalic portion and a tapering posterior extremity. It manifests at an early 2)eriod a tend- ency to elevate itself above the level of the area germinativa. The back becomes arched, and the extremities approximate toward one another. Fluid collects between the two strata of the mesoblast and separates them from one another. Of these, the outer stratum forms a union with the primitive epiblast so as to produce a single membrane, folds of which rise at the same time from the extremities and sides of the embryo, and encompass it with an outer wall or parapet. In the process of growth these folds approach one another over the dor- sum of the embryo, and finally unite together. Thus a sac, including the embryo, is formed, termed the amnion, the cavity of which sub- sequently fills with fluid. Nourishment of the Embryo. It now becomes a matter of importance for us to consider the sources from which the embryo receives the nutritive materials requi- site for its further growth and development. The ovum, in its passage through the Fallopian tube, is increased in size by absorption of albuminous materials from -^ of an inch to from -^ to ^ of an inch. DEVELOPMENT OF THE OVUM. 51 a: a!

In describing the formation of the intestinal tube, it was noted that a portion only of the blastodermic vesicle was included by the curving inward of the inner stratum of the mesoblast, while a portion, known as the umbilical vesicle, hung from the abdomen. The umbilical vesicle is lined, like the intestinal tube, by the hypoblast, and is covered by an extension of the inner stratum of the mesoblast. At first the cavity of the vesicle communicates with the intestine. Vessels from the intestinal tube are dis- tributed over its surface, through the medium of which it contributes to the nourishment of the embryo. This ar- rangement, however, is only temporary. The passage very soon becomes obliter- ated, and the remains of the uml)ilical vesicle hang downward, attached by an impervious pedicle to the intestine. From the time the ovum has passed into the uterus, however, it derives its main nutritive supply from the mucous membrane of that organ, at first by simple absorption, and afterward by the formation of the placenta, an organ through which the blood of the foetus circulates, separated from that of the mother by the thinnest of partitions. Through the party- wall there pass to the foetus all the materials necessary for existence and growth, and from the foetus the excrementitious principles rep- resenting the waste which is inci- dent to vital action. There is nothing in j^hysiology more interesting than the process by which the circulation of the foetus is brought into close rela- tion Avitli that of the mother. It includes the consideration of the allantois, the cliorion, the dccidita, and finally the joint product of them all, viz., the placenta. The Allantois and Cliorion. — The chorion is the external mem- brane that invests the ovum. Before the formation of the amnion it con- sists simply of the zona pellucida or vitelline membrane. As the ovum is received into the uterus the vitelline membrane becomes covered with amorphous villi, which help to fix the ovum in the uterine cavit}^ Fig. 43.— Diagram showing completion of the amnion and formation of the chorion.

Fig. 44.— Human embryo at the third week, showing villi covering the entire chorion. (Haeckel.) After the completion of the amniou by the closure of the amniotic folds it remains for a time attached to the outer lamina of the epiblast, at the point where the folds meet over the back of the embryo. The outer lamina meantime expands until it comes in contact with the vitelline membrane, which then disappears. Thus the outer lamina becomes in turn the external covering or chorion. The new chorion, like the one it superseded, is speedily covered by a growth of non - vascular villosities. These villosities are not solid, but hollow, like the finger of a glove. They soon reach an extraordinary de- velopment. New villi sprout upward from the chorion, the older ones push out buds and lateral ofEshoots, so that already in the third week the entire surface of the ovum is covered with a dense forest of villi, presenting the most delicate and graceful characters. We have just noted that the um- bilical vesicle was a temporary struct- ure, and only for a brief period of physiological importance. Mean- time a new organ is developed, by means of which a vascular connec- tion is established between the em- bryo and the villi of the chorion. This organ is termed the allantois. The allantois begins as a sac-like pro- jection from the posterior extremity of the intestine at the time when the amniotic folds rise up in the form of an embankment around the em- bryo {vide Fig. 43). At this time the umbilical vesicle is still very large. The allantois, like the umbilical vesicle- and the intestine, is composed of two layers derived respectively from the hypoblast and the inner stratum of the mesoblast. It speedily becomes vascular, and increases rapidly in size. The inner surfaces of the sac soon adhere together, so as to form a single membrane.

DEVELOPMENT OF THE OVUM. 53 week the allantois reaches the chorion, over which it spreads and forms a complete vascular lining. According to the usual acceptation, the vessels of the allantois everywhere penetrate into the villi of the chorion. Then the chorion and allantois fuse together, and form by their consolidation a compound membrane termed the permanent cliurio)i.* At first the embryo is connected with the vascular chorion by two arteries and two veins. The two arteries persist as the arteries of the umbilical cord. One of the two veins disappears, while the other becomes enlarged in proportion, and forms the umbilical vein. With the growth of the ovum its surface diminishes in vascularity, except in the neighborhood of the attachment of the allantoic vessels, at which point the villi increase in size and profusion. Over the rest of the ovum the villi atrophy and disappear. Thus the greater por- tion of the chorion becomes smooth, while about one third of its sur- face is covered with a thickened, shaggy portion, destined to contribute to the formation of the placenta. The DeciduSB. — When the ovum passes from the Fallopian tubes into the uterus, it tinds the mucous membrane prepared, by certain changes, for its reception. These changes, as shown in a specimen examined by Dr. Engelmann,f in the first month consisted of a tenfold increase in thickness (two fifths of an inch). The tissues were intensely vascular, and the entire mucous membrane was thrown into convolutions. The thickening was mainly due to an increase in the elements compos- ing the interglandular connective tissue. This was more especially the case in the upper layers, where the cells were like those of young connective tissue. A soft, pulpy Fig. 46.-Formatii>n of deoldua, first stage. state of the mucous membrane was occasioned by an augmented production of the amorphous inter- cellular substance which characterizes connective tissue in the embry- onic state. It is this thickened, vascular, softened mucous membrane which furnishes the decidua vera. The ovum, soon after its entry into the uterus, finds a lodgment in one of the folds of the decidua vera.

It is physiologically important as the site of the placenta. The ovum is not simply adherent. It lies, as it were, imbedded in the tumefied membrane, folds of which grow up around it, and finally meet so as to inclose c it in a cavity of its own, shut oft" from the general cavity of the uterus.* The folds of mucous membrane wliich inclose tlie ovum are termed the decidua rejiexa. Tlie space between the decidua vera and ru- flexa is filled by opaque, viscid mucus. The Placenta, — The villi which cover the chorion become imbedded in the soft tissues of the decidua, and derive, by absorption, nutritive materials from the circulatory system of the mother. After the for- mation of the permanent chorion, by the extension of the allantois to the inner surface of tlie Q^g., the allantoic vessels convey the absorbed materials directly to the embryo. At first, absorption takes place from the entire circumference of the chorion, but with the enlargement of the ovum there ensues a thinning of the reflexa, with obliteration of its vessels. At the same time the villi cease to grow over that portion of the chorion in contact with the reflexa, and the whole process of exchange between foitus and mother becomes concentrated at the de- cidua serotina. At this point the chorion, in place of becoming bare, is covered with an infinite multitude of villi, which enlarge, lengthen, and, by sending out lateral offshoots, assume an arborescent appear- ance. The villi are arranged in tufts, sixteen to twenty in number, which together form a soft, spongy mass, and constitute the fetal portion of the placenta. The uterine mucous membrane, in which the villi lie imbedded, contributes likewise its share to the muke-up of the completed pla- * Leopold, in his account of the uterine mucous membrane, adopts Reichert's view of the formation of the reflexa. viz., that, owin^ to the less rapid increase in the growth of the serotina, the ovum becomes buried in the thickening of the vera. — {Vide Studien ilberdie Uterusschleimhaut. etc., Arch. f. Gynaek., Bd. xi, p. 455.) In opposition to the accepted view that the decidua is the tumefied mucous mem- brane, Ercolani (On the Utricular Glands of the Uterus, translated by Marcy) insists that both the vera and reflexa are organs of new formation, the products of exudations, the neo-formative process consisting in the production of new vessels with single endothelial walls, from tbe surface of which the decidual cells are elaborated. DEVELOPMENT OP THE OVUM. 55 centa. The structure of this so-called maternal portion of the organ has been the subject of much difference of opinion. Indeed, an in- telligible idea of its anatomy can hardly be conveyed without a pre- liminary consideration of certain points connected with its develop- ment. Thus, the villi are often erroneously described as penetrating direct- ly into the glandular structures of the adjacent uterine mucous mem- brane. Professor Turner has, however, conclusively shown that, in all the less complicated placental forms throughout the animal kingdom, the depressions or cryjits into which the villi dip occupy the soft, pulpy, interglandular tissues. Engelmann further draws attention to the large size of the terminal sprouts of the villi in the human placenta, which would render their entrance into the glandular tubules, unless by a mere exceptional chance, a mechanical impossibility. Moreover, Friedliinder * has demonstrated, as will be again noted hereafter, the persistence of the enlarged flattened glands in the serotina even after the separation of the i)lacenta at childbirth. It may be deemed, there- fore, as fairly settled that the maternal portion of the placenta is de- rived from the tissues occupying the spaces between the glands, and not from the glands themselves. In the mare, the relations of the villi to the uterine mucosa are of the simplest character. With a little force it is possible to draw the villi from the crypts, which, on vertical section, are seen to be cup- like depressions between the glands. The crypts are surrounded by a dense capillary plexus, and are lined by eiDithelial cells. The epi- thelial cells are partly columnar, like those covering the mucous membrane of the uterus in the unimpregnated state, while others are so swollen out that their length but little exceeds their breadth, while others are of irregular shape. Transitional forms prove the derivation of the irregularly shaped cells from ordinary columnar epithelium, f In the arrangement just described, it will be seen that the villi containing the vessels communicating with the foetus dip into crypts in the uterine mucous membrane. The crypt-walls are highly vascu- lar, and are lined with epithelium. There is, therefore, no direct com- munication between the fetal and maternal blood-vessels. The crypts, however, elaborate a secretion, termed by Haller uterine milk, which contains fatty, saline, and albuminous matters dissolved in water. The uterine milk is, therefore, well qualified to serve as a nutrient mate- * Friedlander, Untersuchungen iiber den Uterus, 1870— Ueber die Innenflache des Uterus post partura, Arch. f.

Vertical sections show that the walls of the crypts closely follow the sinuosities of the villi in such wise as to form an intimate investment for them. Injections of the maternal capillaries show them to be dilated to two or three times the size of the capillaries in the fetal villi. f In the human placenta the relations of the villi to the uterine mu- cous membrane differ somewhat at different stages of development.

Next, as the villi sprout and become vas- cular and arborescent, projections formed from the proliferation of the superficial portion of the serotina grow around the oft'shoots and branching processes. At this time we distinguish in the placenta a fetal portion, the placenta foetalis, composed of the villous tufts of the * The uterine milk can not be obtained from the placenta of the mare unmixed with the secretions from the uterine glands. The analyses of Professors Prevost. Schlossberger, and Gamgee were made upon a fluid derived from polycotyledonous placenta?.— ( Vide Structure of the Placenta, p. 176.) Hoffmann (Sicherer Xachweis der Uterinmilch beim Menschen, Ztschr. f. Geburtsk. und Gynaek, Bd. vili, p. 258) claims to have demonstrated the presence of uterine milk in the human placenta likewise. This he obtained by the insertion of capillary tubes into the substance of the placenta from its maternal surface. The fluid consisted of serum, of some of the formed elements of the blood, and of a multitude of spherical bodies which he regarded as analogous to m.ilk globules. Werth, however (Ueber die sogenannte Uterinmilch des Menschen. Arch, f, Gynaek.. Bd. xxii. p. 233), has shown that this so- called uterine milk is a post-mortem production, not present directly after delivery ; that the serous portion is derived from the villi, and the formed elements from the exochorial cells. f Turner, op. cit., pp. 155, 156. DEVELOPMENT OP THE OVUM. 57 ovum, and a uterine portion, the placenta uterina, derived from the tissues of the serotina. In the third and fourth months the union of the fetal and maternal tissues is very intimate. But subsequently the growth of the uterine tissue does not keep pace with that of the villi, so that the mature placenta is almost altogether a fetal organ. A layer of uterine mu- cosa, not exceeding ^^ of an inch in thickness, covers the surface of the placenta after delivery. Between the cotyledons, however, thin partitions from the serotina extend downward for a considerable dis- tance, thougli never, except near the borders, as far as the chorion. Sections through the hardened placenta show that the main villous trunks divide at a short distance from the chorion. The secondary branches assume a radiate direction, from which proceed tertiary branches, which terminate in club-shaped extremities and bury them- selves in the serotina. From these tertiary branches fine lateral ones, having a dendritic arrangement, are given off, and fill the spaces be- tween tlie tertiary trunks. Many of these lateral tufts are attached directly to the serotina, and fill up in part the interval between the larger radiate branches ; others, again, float freely in the blood-currents derived from the ma- ternal vessels.* The precise origin and nature of the vascular spaces between the villi have been a prolific subject of discussion. In the early months, we saw, the scrotinal projections extended deep down between the villi, and contained largely dilated capillaries ; and yet afterward every trace of these vessels is found to have disappeared throughout the entire placenta, except in the thin layer of the placenta uterina, where the endothelium, or inner lining, may still be detected. The most probable supposition is, that the vessels have become eroded and finally destroyed by the growth of the villi, leaving the blood to flow unimpeded tlirough the intervillous spaces. A delicate layer of epithelium may, indeed, be found upon the villous trunks and tufts ; but these, it is sufficiently established, belong to the villi, and are de- rived from the exochorion.f Whether these cells essentially modify the interchange between the fetal and maternal circulations, can only be a matter of conjecture. The fact that certain medicinal substances, such as iodide of potassium and salicylic acid, when administered dur- * Langhans, Zur Kenntniss der menschlichen Placenta, Arch. f.

It is, however, proper to state here that Ercolani maintains that the dilated endothelial walls of the maternal vessels are simply bent inward by the proliferating villi, and that the epithelium observed upon the villi are decidual, and are not derived from the exochorion.

Heinz states that on the bor- ders of the placenta a portion of decidual ti.'^sue is pushed under the placenta (2 to 3 cm.), and at this point septa may be found penetrating the placenta to the subchorial layer of the decidua. Detached portions of decidual tissue sometimes are found in placental tissue. At term the villi have no epithelial covering. In the early months cell coverings may be seen here and' there, but are derived from the villi. The remains of glandular structures described by Friedlander, after separation of decidua, are not found in the serotina at the end of pregnancy. The separation must therefore take place from the borders in the puerperal period, when the point at which placental separation has taken place is of small .size. Heinz observed specific instances where the villi penetrated directly into the lumina of the decidual glands, but leaves open the question whether they likewise , penetrate into the interglandular tissue. Heinz's view of placenta formation is as follows: Villi DEVELOPMENT OP THE OVUM. 5q in their distribution over tlie surfuce of the organ previous to plung- ing into the tissues beneath. The uterine surface has a peculiar, gran- ular feel, and is divided into a number of lobes, corresponding to the fetal tufts or cotyledons already described. It is covered with a soft, thin membrane, which sends septa or partitions in between the cotyle- dons. This membrane is simply the product of the surface layer of the serotina. Curled arteries from the uterus penetrate the cotyledons, and con- vey the maternal blood into the spaces or lacuna? between the fetal tufts. Through these spaces the blood flows in a sluggish current, and is conveyed back to the uterus by the coronary vein upon the margin of the i)lacenta, and by means of sinuses situated in the septa between the cotyledons, and continuous with the venous sinuses of the uterine walls.* The fetal tufts which thus bathe in the mother's blood receive, through the umbilical arteries, the blood which comes from the fcetus, darkened with carbonic acid. In the ultimate rami- tications of the villi, the arteries communicate by an arch or loop with a corresponding branch of the umbilical vein, which returns to the cliild red, arterialized blood. f liut the placenta is not simply a respiratory organ. The rapid de- velopment of tlie ovum, from a simple cell of microscopic size to the proportions of the infant at birth, argues as surely that the relations of the blood-currents in tiie placenta enable the fcetus to derive from the mother all the proximate principles required for the building up of tissue, the diiferentiation of organs, and the performance of function. Then, too, the fa?tus has been shown to have a temperature of its own, somewhat higher than tluit of the mother.]; This production of heat is necessarily attended with destruction of tissue. Of this there penetrate tlie deoidim and chiefly enter gland stnictnres, break through the gland wallj:. and destroy maternal tissue, with the exception of small remnants, which per- sist as islets. Villi grow into dilated vessels, and bathe freely in them. The opened vessels pour the l)lood into the intervillous spaces. In the mature placenta there remains of decidua only the serotina, one half to one millimetre thick. The septa and the islets are evidence that serotinal tissue once existed near the chorion, but was destroyed by growth of villi. * For alTirmative evidence f)f the existence of placental lacunae, vide Professor TcRXER, Structure of the Human Placenta, Jour, of Anat. and Physiol., vol. vii, p. 120.

There can be little question, however, but that the placenta furnishes the chief channel through which the devitalized products are discharged. The Formation, of the Umbilical Cord. To understand the structure of the cord, it is well to bear in mind the various particulars connected with its development. At the time when the allantois first appears as a sac-like projection from the intes- tine, the embryo is hardly more than an appendage to the umbilical vesicle. The larger size of the latter directs the allantois over the posterior extremity of the foetus. By its growth and extension, the Fig. 50.— a, umbilical arteries forming spirals (1 ]') around the vein ; constrictions indicating the presence of folds (3, 3'); circular folds (.5, .5'); lateral openings showing the arterial walls. B, vein opened upon the side, showing a constriction (2) correspondiiiK to an interior valve (3"i; semi-lunar valves (3, 3', 3") C, section of vein and arteries showing valve of vein (1», a semi-lunar arterial valve (2), and a circular arterial valve (3). (Tarnier et Chantreuil.) allantois reaches the chorion, and forms a sort of pedicle, by means of which a vascular communication is established between the embryo and the periphery of the ovum. This pedicle is the first indication of the umbilical cord. Its vessels become reduced to two arteries, the umbilical arteries, and a single vein, the umbilical vein. Meantime, the umbilical vesicle diminishes in size, and finally shrinks to a mere thread. The amnion fills with fluid, exuded probably from the body of the foetus, and continues to expand, so that often by the end of the DEVELOPMENT OF THE OVUM. 61 second month it comes in contact with the chorion.* In this way it forms a reflection over the pedicle of the aUantois, which it invests like the finger of a glove. Finally, the structure of the cord is com- pleted by the formation of an elastic substance, termed the gelatine of Wharton^ which consists of connective-tissue elements inclosing large spaces containing amorphous matter. The gelatine of Wharton func- tionally serves to protect the vessels of the cord from compression. It is formed by hypergenesis from the outer layers of the amnion and the allantois, both of which are derived from the intermediate layer, described in the development of the foetus {vide p. 50). The interme- diate layer furnishes, likewise, the connective tissue of the body. The fully-developed cord consists, therefore, of a sheath from the amnion, the gelatine of Wharton, the umbilical vein and arteries, and traces of the umbilical vesicle,f and the pedicle of the allantois.J It averages twenty inches in length, though it has been observed as long as seventy inches, and as short as two and a half inches.* A long cord predisposes to the formation of coils about the neck, body, and limbs of the foetus. It is usually of about the size of the little finger, but is very variable, its circumference depending chiefly upon the quantity of the gelatine of Wharton. The arteries are so twisted as to form spiral turns around the vein, and, owing to the superior length of the right artery, in most cases in the direction from right to left. As an anatomical peculiarity, may be mentioned the fact that the walls of the arteries are only slightly thicker than those of the vein. The arteries as well as the vein contain semi-lunar valves. The Amniotic Fluid. — The origin of the amniotic fluid in the ear- lier months of gestation is not known, the most probable suggestion being that it is simply exuded from the tissues of the foetus. After the formation of the placenta, a capillary network, connected with the vessels of the umbilical cord, is developed just beneath the amnion in that portion of the chorion which covers the placenta. From these vessels a transudation of serum takes place into the cavity of the amnion. II After the first half of pregnancy has been reached, the capillary network disappears. The continued increase of fluid in the amnion in the later months of gestation is possibly due to the accu- mulation of urine, which the fcetus passes intermittently during intra- uterine existence.^ The composition of the amniotic fluid corresponds * Vide Hunter's Gravid Uterus, plate xxxiii, Fig. 2 ; Ecker, Icon.

In addition to water it contains albumen, urea, and the saline substances which are found in serum and urine. Its quantity varies usually between one and two pints, of which nearly one half is contributed during the last three lunar months.* Ahlfeld concludes from the great quantities of lanugo found in the meconium that the child of necessity during intra-uterine life swallows a very considerable quantity of amniotic fluid. As no fluid is found at birth in the intestinal canal, the fluid was of necessity absorbed. As the amniotic fluid contains albumen, in certain cases the precipitate amounting to from twenty-five to fifty per cent, he believes this al- buminosus contributes something to the nourishment of the child. Richard Schroeder, on the contrary, regards the quantity of albumen in the amniotic fluid as too small to contribute appreciably to fetal nutrition. CHAPTER III. DEVELOPMENT OF THE F(ETUS. Development of the foetus in the successive months of pregnancy. — Fetal circula- tion. — Fcetus at term. — Fetal cranium. — Attitude, presentation and position of foetus. Development of the Fcetus ix the Successive Months of Pregnancy. It is customary to reckon the duration of pregnancy at two hun- dred and eighty days, and to divide that space into ten months of twenty-eight days each. As it is often a matter of importance that an accoucheur should be able to judge the age of a prematurely expelled embryo or fcetus, the following particulars concerning the olianges in each month are furnished as a guide to the formation of an ojnnion. In the writer's experience all rules regarding the age of the ovum pos- sess, however, nothing more than an approximative value, owing to the very great normal variations in the rapidity of development in different individual cases. First Montli. — At the end of the second week, the embryo is repre- sented by the embryonic spot, which has assumed a biscuit-shape. The dorsal plates are developed. The entire ovum measures one fourth of an inch, and the embryo one twefth of an inch. A week later the embryo has doubled in length, and presents as special features a curv- mentelle Untersuchungen ueber die Herkunft des Fruehtwassers, Arch f.

DEVELOPMENT OF THE FCETUS. 63 mg of the back, an enlargement of the cephalic extremity, with rudi- ments of the three higher organs of special sense, and the appearance of the visceral arches. The amnion is fully developed. The embryo is nourished by the umbilical vesicle. The allantois carries the vessels from the embryo to the periphery of the ovum, but the vessels do not penetrate the villi. An ovum described by Waldeyer, exactly four weeks old, was of about the size of a pigeon-egg, and three fourths of an inch long by two thirds of an inch broad. It weighed upward of two scruples. The embryo measured nearly one third of an inch in Fig. 51.— Human germs or embryos from the second to the fifteenth week (natural size), seen from the left side, the arched back turned toward the right.

The head of the embryo presented the primitive cerebral vesicles. The eyes were in the sides of the head, and the ears posterior to the eyes. Beneath, the visceral arches were well marked. Four bud- like processes indicated the beginnings of the anterior and posterior extremities. The intestine, with anal and oral openings, was formed. The cord was short and thick, with a single vein and two arteries. The amnion was only moderately distended, and space still existed 64 PHYSIOLOGY OF THE OVUM. between the amnion and cliorion The umbilical vesicle was tolerably large. Second Month.— An embryo described by Waldeyer from the sixth to the seventh week measured about one inch in length, following the dorsal curve. Another in the eighth week described by Ecker meas- ured two thirds of an inch in a direct line from the head to the caudal curve.* The ovum itself was of about the size of a hen's egg. The amnion at the end of the second month is distended with fluid and in contact with the chorion. f The villi become abundant near the im- plantation of the umbilical cord. The umbilical vesicle is greatly re- duced in size, and hangs from the embryo by a slender pedicle. The umbilical cord is increased in length, but its vessels do not yet assume a spiral direction. The umbilical ring is small, though still containing loops of intestine. Ossification begins in the lower jaw and clavicle. The three divisions of the extremities are clearly indicated. Third Month. — Toward the end of the third month the ovum meas- ures nearly four inches in length. The embryo is between three and three and a half inches long, and weighs about an ounce. The chorion has lost in great measure its villosities. The placenta is formed, though of small size. The cord lengthens, and forms spiral turns. The neck now separates the head from the trunk The development of the ribs distinguishes the thorax from the abdomen. The mouth is closed by the lips, and the nasal se2)arated from tiie oral cavity by the palate. Points of ossification appear in most of the bones. Thin, membrane- like nails appear upon the fingers and toes. The scrotum and labia majora begin to form from cutaneous folds. The penis and clitoris do not difl:er from one another in length. Fourth Month. — Toward the end of the fourth month there is an increase of size and thickness in the placenta. The cord is increased to two or three times the length of the fatus, and has become thicker from the formation of the gelatine of Wharton. The fwtus measures four to six inches in length. The weight is estimated all the way be- tween two and four ounces. The head of the ftetus is one fourth the length of the entire body. The bones of the skull are partly ossified. The sutures and fontanelles are widely separated. The mouth, eyes, ears, and nose assume their proper shape. The sex is distinguishable, the skin firmer, and hair begins to form upon the scalp. The foetus makes slight movements with its limbs. Fifth Month. — The foetus measures from seven to ten inches in length, and weighs nearly ten ounces. The head is still relatively large. The face, however, is wrinkled, and wears a senile aspect. Fine hair (lanugo) appears over the whole surface of the body. The fetal movements are now distinctly felt by the mother. * Spiegelberg, Lehibuch der Geburtshiilfe, p. 84. f Loc. ciL, p. 84. DEVELOPMENT OF THE FCETUS. 65 Sixth Month. — Near the end of the sixth month the foetus is eleven to thirteen inches long and weighs about twenty-three ounces. The deposition of fat in the subcutaneous cellular tissue begins. The eye- lids separate. A foetus born at this time breathes feebly, but in the course of a few hours dies. Seventh Month. — The fa?tus measures fourteen to fifteen inches, and weighs in the neighborhood of thirty-nine ounces. The skin is still wrinkled, of a red color, and covered with vernix caseosa. Children born between the twenty-fourth and the twenty-eighth week move their limbs and cry feebly at birth, but in spite of every care they die in the course of a few hours or days. Note. — Ahlfeld has recently suggested the inquiry as to whether the assump- tion that children born before the completion of tlie twenty-eighth week neces- sarily perish is not too arbitrary. Many practitioners have observed instances of the survival of a premature child which, both from the data obtained from the parents and from all the indications presented by the child, they at the time of birth had placed within tlie limit regarded as hopeless. Ahlfeld has culled a num- ber of such cases from the published literature of the subject. Granting the many sources of error which would lead us to accept such cases with caution, it none the less seems incumbent upon us to regard Ahlfeld's advice, and look upon every child which respires at birth as one whose life may possibly be preserved by suitable care. It may be that the skepticism of medical men is in part the cause of the unfavorable results.* Eighth Month. — The foetus measures sixteen to seventeen inches, and weighs upon the average about fifty-two ounces. The pupillary membrane disappears ; the hair of the head increases in thickness ; the lanugo begins to disappear from the face ; the nails are harder, but do not yet reach the tips of the fingers. Usually, in boys, a testicle may be felt in the scrotum ; the navel is situated nearly in the center of the child's body. With care, the life of a child born within this period may be preserved. Ninth Month.— The length is between sixteen and a half and seven- teen and a half inches ; the weight is about sixty-four ounces ; the body becomes rounded and the face more comely, losing its wrinkled, anti- quated aspect; the bones of the head bend easily, and the lanugo begins to disappear from the body. Children at this period are less energetic than at full term, sleep a great part of the time, and are prone to die with lack of careful attention. Tenth Month.— In the first two weeks the fa?tus measures eighteen to nineteen inches, and weighs about seventy-seven ounces, f * Ahlfeld, Ueber unzeitig und sehr fruhzeitig geborene Friichte die am Leben blieben.

Observations of Fesser showed similar results. (Lehrbuch der Geburtshiilfe, von Otto Spiegelberg, 1877, p. 86.) Ahlfeld obtained considerably larger averages from 250 observations in which 5 g^ PHYSIOLOGY OP THE OVUM. For convenience of reckoning from memory it is sufficiently accu- rate to assume the length of the child in the third and fourth month at respectively three and four inches. In the fifth, sixth, seventh, and eighth months close approximations to the average length may be obtained by doubling the number of months. In the ninth and tenth months the length may be placed respectively at seventeen and eight- een inches. The Fetal Circulation. — The umbilical arteries at first take their origin from the inferior vertebral arteries, and afterward from the hypogastric or internal iliac arteries. The umbilical vein enters the abdomen at the navel, and thence passes to the lower surface of the liver; it gives off a number of branches to the left lobe, the lobus quadratus, and the lobus Spigelii. At the transverse fissure it divides into two branches, the larger of which empties directly into the portal vein, and supplies the right lobe with umbilical blood ; the other passes to the inferior vena cava, and is termed the ductus venosus. Thus the greater portion of the regen- erated blood, brought by the umbilical vein from the placenta, first passes through the liver before entering the general circulation of the foetus, while the lesser amount empties at once into the inferior vena cava. As, however, with the advance of gestation, the relative dispro- portion between the hepatic trunks and the ductus venosus is in- creased, toward the end nearly all the blood from the placenta has to make the circuit of the liver. Thus the inferior vena cava carries to the right auricle, in part, blood from the lower extremities charged with effete matters, and, in part, placental blood, either received direct from the umbilical vein through the ductus venosus, or after having previously traversed the liver. In the foetus the currents of blood through the heart are especially adapted to the unexpanded condition of the pulmonary organs. Previ- ous to the first respiratory act at birth, the lung is small, and, were the entire contents of the right side of the heart, as in the adult, at once discharged into the pulmonary vessels, intense engorgement with rupture of the capillaries would ensue. This danger is, however, averted by the anatomical peculiarities already stated. Thus, in the early months the blood from the inferior cava, in place of emptying from the right auricle into the right ventricle, passes directly across the right auricle, guided by the Eustachian valve, through the foramen ovale to the left auricle, and thence to the left ventricle. As the heart contracts it enters the aorta, and is distributed by the large vessels which spring from the latter to the head and upper extremities. The blood returned from the upper portion of the body by the superior the date of conception could be determined. (Bestimmungen der Grosse und des Alters der Frucht vor der Geburt, Arch. f.

With the advance of gestation, however, a gradual disappear- ance of the Eustachian valve takes place, so that a part of the blood from the inferior cava enters with that of the superior cava into the right ventricle. The contraction of the right ventricle forces the blood into the pulmonary artery, which distributes an insignificant quantity to the lungs, while the main current passes through the ductus arteri- osus into the aorta, ly which it is distributed to the lower portion of the body. Thus it will be noted that at all times provision is made for sup- plying the head and upper parts of the body with regenerated placen- tal blood. On the other hand, the lower extremities are for a time almost entirely supplied with blood which has already fed the tissues and received the waste of the upper portion of the body. As preg- nancy, however, advances with the disappearance of the Eustachian valve, a small measure of placental blood is likewise distributed to the lower portion of the body. This is in unison with the well-known fact that the relative development of the lower extremities increases as the end of gestation is approached. With the cessation of the placental circulation at birth, the um- bilical vessels close, with the exception of the umbilical arteries, which remain pervious at their lower portion and constitute the vesical arte- ries. After the establishment of respiration, the blood from the right side of the heart makes the circuit of the lungs and returns to the left side by the pulmonary veins. The ductus arteriosus then contracts and disappears. As the left auricle fills with blood, the pressure closes the valve of the foramen ovale. Occasionally, however, the foramen ovale remains open after birth, and allows a portion of the venous blood to pass from the right to the left auricle. We have then one form of the condition known as cyanosis neonatorvm^ an affection characterized by intermittent attacks of dyspnoea, blueness of the sur- face of the body, and depression of the temperature. The Foetus at Term.— In the child at birth the body is well rounded, and the skin has lost its deep-red coloring ; the fine down (lanugo) has, for the most part, disappeared ; the nails project beyond the fin- ger-tips ; in the male the scrotum contains both testicles, and in the female the labia majora are in "contact. In the fifth month the sur- face of the fetal body is covered by the vernix caseom, a whitish sub- stance composed of a commingling of surface epithelium, down, and the products of the sebaceous glands. This coating probably protects the skin during intra-uterine life from the penetration of the amniotic fluid. The amount of this substance upon the body is very variable at birth, when it is chiefly found upon the back and flexor surfaces of the extremities. Children at term cry lustily soon after birth, move their limbs DEVELOPMENT OF THE FCETUS. 69 freely, and nurse when put to the breast. In the first few hours they pass urine and the so-called meconium^ a mixture of intestinal mucus with epithelium, epidermis cells, lanugo, and bile, which gives to it a black or brownish-green color.* The average length at birth is from twenty to twenty-one inches. The average weight seems to be, in some degree, dependent upon race peculiarities. Scunzoni f found, in nearly 0,000 births, an average for both sexes of nearly seven pounds. Ingerslev,J in Copenhagen, from statistics based upon 3,-450 births, arrived at nearly the same results. Hecker,* in Munich, out of something over 1,000 births, obtained six and four fifths pounds as the average ; wliile Fesser, || in Breslau, found it only six and a half pounds. Bailly ^ likewise reports the average weight as something less than seven pounds. The weights of 200 infants born in the Bellevue Hospital gave to the writer an average of seven and two thirds pounds for the two sexes. The boys averaged seven and nine tenths pounds, and the girls seven and one third pounds. Three fourths of the mothers were of Irish birth, one fifth were born in America, while the remaining fraction was divided be- tween English, Scotch, and Germans. The largest child weighed eleven pounds. Ingerslev's largest child weighed ten and three eighths pounds ; Hecker found two weighing between ten and eleven pounds ; La Chapelle, out of 7,000 cases, found thirteen infants weighing ten pounds, but none exceeded that limit. Credible histories I) of children weighing from twelve to sixteen pounds are extant; such children have often been still-born. Waller, however, J reports a case of a living infant delivered by him with forceps, which weighed fifteen pounds fifteen ounces. I have extracted with forceps a living child which weighed over fifteen pounds. Dr. C. W. Gleavis, of Wytheville, Va., writes me that a lady in that place gave birth to a living male child which weighed eighteen pounds. The size of the child is influenced in especial by — 1. The sex. Boys average a greater weight than girls. 2. The number of pregnancies. The children of primiparae average less than those of multiparfe. The increase in weight of children in each successive pregnancy is progressive, though this law is liable to in- terruption where pregnancies follow one another too rapidly, or in cases * ZwEiFEL, Untersuchungen iiber das Meconium, Arch. f.

The constitution and health of the parents. By some, too, the size of the father is sup^josed to exercise an influence upon that of the child. The Fetal Cranium.— Except in children of exaggerated size, the head is the most voluminous and unyielding part which has to traverse the parturient canal.* The diameters of the head and the physical char- acters of its bones are chiefly of importance in connection with the mech- anism of labor. Their consideration may, therefore, be conveniently postponed to the study of that subject. A knowledge, however, of the general structure of the skull is essential to the diagnosis of pregnancy. The face is very small in proportion to the cranium. The latter consists of the two frontal bones, the two parietal bones, the occipital bone, the temporal bones, and the alfe of the sphenoid bone. At birth these various bones are not, as in the adult, directly articulated together, but are united by means of fibrous bands, termed sutures, in which ossi- fication subsequently takes place. It is important to become familiar with the following sutures : 1. The fronfal xnture, between the frontal bones. 2. The sagittal suture, between the two parietal bones. 3. Tlie coronal siiture, between the frontal and parietal bones. 4. The lambda suture, between the occipital and two parietal bones. When three or more bones meet together, the rounded angles of the bones offer at the point of concurrence a deficiency of osseous substance, which is closed by fibrous membrano similar to that which forms the sutures. These membranous interspaces are termdd foyitanelles. Two of these, the large anterior and the small posterior fontanelle, are of immediate obstetrical interest, as they, with the sutures, furnish the guiding points which enable the examining finger to determine, in ad- vanced pregnancy, the position of the child's head. The large fontanelle, or bregmatic space (bregma, the sinciput), occupies the gap between the parietal and frontal bones. It possesses a lozenge-shape. Its anterior angle is continuous with the frontal suture, its posterior angle with the sagittal suture, and its lateral angles with the two halves which compose the coronal suture. Its an- terior angle is much longer than the posterior angle. The small fontanelle is situated at the junction of the occipital with * Wernich, Ueber die Zunahme der weiblichen Zeugungsfahigkeit, Beitr. zur Geburtsh., Bd. 1. p. 3. t Duncan, Fecundity, Fertility, and Sterility, p. 53.

As a rule, it no longer exists at birth, owing to the complete ossification of the angles which form it. The anterior fontanelle may be recognized by the finger, during labor, by its large size, its lozenge-shape, and by its four converging sutures which cross one another at right angles. The posterior fon- tanelle, on the contrary, is small and triangular ; the sagittal suture forms, with the lambda suture, an obtuse angle on either side, and ter- minates at the occipital bone. During the descent of the child's head into the pelvis, the occipital bone is frequently depressed beneath the parietal bones, which thus form a relief, along which the finger readily passes to the site of the small fontanelle, even when the latter no longer exists as an open gap or space. The Attitude, Pkesentatiox, and Position of the Foetus. The attitude of the foetus i/i ntero is as follows : The spinal col- umn is bent forward, the chin is inclined toward the chest, the arms are bent at the elbow and the forearms are crossed upon the breast, the thighs are flexed upon the abdomen, and the feet extended so as to come in contact with the legs, which, like the forearms, are often crossed. By this arrangement the fci'tus assumes the smallest bulk, and presents an ovoid form, of which the head furnishes the smaller end. By presentation we understand that portion of the foetus which oc- cupies the lower segment of the uterus. By the determination of the presentation, we are enabled to decide upon the relation of the axis of the child to the long diameter of the uterus. When these two coin- cide, either of the two extremities of the child, viz., the head or the breech, becomes the presenting part. When the long diameter of the child corresponds to the oblique or transverse diameter of the uterus, the shoulder becomes the presenting part. Though head-presentations form, during labor, by far the large majority of all cases (ninety-six per cent.), changes of position are very common during pregnancy. The frequency of these changes is in inverse ratio to the advance of pregnancy, occurring with diminished frequency in the later months. In multiparae they take place oftener than in primiparae. In multiparse they occur not rarely shortly before birth, while it is exceptional in primiparae for them to take place in the last three weeks of pregnancy. Great ingenuity has been exercised to account for the preponderating frequency, at the time of labor, of head-presentations. Hippocrates taught that, during the early months of pregnancy, the fojtus occupied a sitting posture, with the head uppermost. In the seventh month, however, it made a complete turn or somersault preparatory to its exit from the womb, an act DEVELOPMENT OP TUE FOETUS. 73 accomplished by the vohmtary efforts of the child. Aristotle referred the head-presentations to the laws of gravity, a theory which has always had many adherents and is still actively defended at the pres- ent day.* Dubois f made a serious breach in this doctrine by showing that if he allowed a dead fa?tus, of any period between the fourth and ninth months, to sink in a vessel filled with water, it was not the head, but the back or right shoulder which first reached the bottom. Dubois there- upon denied the influence of gravity, and referred the head-presentations to instinctive or voluntary movements on the part of the foetus, designed to bring it into a position best adapted for intrauterine domicile, or for par- turition. He likewise argued against the gravitation theory, that in pre- mature births, and in children who die in utero, pelvic and transverse pre- sentations are very common — a fact that would be inexplicable were grav- ity the sole or chief force in opera- tion. Simpson J agreed with Dubois in ascribing the cephalic presentations to fetal movements, but, in place of the instinctive or voluntary movements of Dubois, substituted, in an argument of extraordinary ingenuity, a theory of reflex action. Thus, the frequency of mal-positions in the first six months of pregnancy was explained by the spheroidal shape of the uterine cavity, which allows of unrestrained fetal movements. In the later months, however, as the uterus assumed a more ovoid shape, it was only when the child was situated in the uterus with the head lowest that a physical adaptation between icetus and uterus existed. In case from any cause, therefore, a deviation from this, the normal position, took place, the pressure upon the cuta- neous surface of the child, by the uterine wall, would give rise to excito- * Vide historical part of Cohnstein's paper entitled Die Aetiologie der normalen Kinderlage, Monatssch. f.

Duncan* and Yeit succeeded in partially re- habilitating the gravitation theory by sliowing that, notwithstanding Dubois's experiinents, the center of gravity lies much nearer the cephalic than the pelvic extremity of the child. They found that a fresh fa?tus immersed in a saline fluid possessing nearly the same spe- cific gravity as the foetus, in place of sinking upon its back or side to the bottom of the vessel, assumed an oblique direction in the fluid with the right shoulder looking downward, f They therefore con- cluded that the foetus, lying upon the inclined plane furnished by the uterine walls, would naturally assume a similar position were no other forces operative to interfere. Crede, Kristeller,| and Braxton Hicks* maintain that the contractions of the pregnant uterus adapt the position of the foetus to the form of the uterus. Veit believes that the stability of the foetus is insured by the descent in advanced pregnancy of the presenting part below the level of the pelvic brim. Now, each one of these conflicting ideas undoubtedly represents a portion of, but not all, the truth. It is certain that the influences cited do exist, and it only remains for us clinically to assign to each its relative value. In the early months of pregnancy, the spheroidal shape of the uterine cavity, the small size of the fcrtus in comparison with that of the uterus, and the large proportion of amniotic fluid, all allow the foetus the greatest measure of mobility. At this time the position of the child must be influenced by the active movements which are felt by the mother subjectively often as early as the four- teenth week. As usually, during the first half of pregnancy even, the shoulder and head are turned downward, it is fair to ascribe tliis position to the laws of gravity. The frequency of malpresentations in premature labors is explained in part by the tardy dilatation of the cervix and the mobility of the foetus, which render easy the displace- ment of the head from its first position, under the influence of pressure exerted upon the axis of the child's body. Malpresentations are more frequent in the case of a dead foetus than in the living, but Duncan has shown that in the dead foetus, owing to post-mortem changes, the center of gravity often shifts toward the pelvic extremity. With the advance of pregnancy, as the longitudinal exceeds the lateral growth of the uterus, the child adapts itself to the long axis of the uterus, and the furthei pregnancy advances the more complete the adaptation becomes. When from any cause or condition the correspondence be- tween the fetal and uterine axis is disturbed, compression of a portion of the cutaneous surface of the foetus results.

I DEVELOPxMENT OF THE FCETUS. ^5 especially in the lower extremities, are excited, which restore the fcetus to that position in which it enjoys the most complete freedom from discomfort. Often, too, the uterine walls resent the pressure of the foetus, and, by their contractions, serve to maintain the body of the child in the uterine axis. In cases of hydramnios the conditions more nearly resemble those which exist in early pregnancy ; hence malpresentations occur with greater frequency, favored by the mobility of the fcetus in the surplus- age of amniotic fluid. Per contra, when, as is the case toward the end of normal pregnancies, the fcetus nearly fills the intra-uterine space, the movements are very restricted, and displacements rare. In primiparous women, the pyriform shape of the uterus in the later months is most marked, and as a consequence the head of the child is usually held by the uterine walls in the pelvic cavity. In multipara?, on the contrary, owing to the relaxation of the uterine parietes, it) is usual for the child, in obedience to the laws of gravity, to lie somewhat obliquely in the uterus, with its head resting upon one of the iliac fossa?. As soon as labor begins, however, the uterine con- tractions carry the head to the axis of the superior strait of the pelvis. The changes in the fetal presentation are not, however, confined to simple conversions from an oblique to an upright direction, or to shiftings of position iy obedience to laws of gravity. But even in ad- vanced pregnancy a breech-presentation may become a head-presenta- tion, and vice versa* P. Miiller reported a case in which the foetus made six such revolutions within five days.f Now, it can not be sup- posed that the difficulties which the foetus must encounter from the resistance of the short transverse diameter of the uterus could be over- come by such comparatively feeble forces as gravity, or reflex adapt- ive movements, or partial uterine contraction. In Miiller's case the changes, if the mother's story be correct, must have taken ^place not gradually but suddenly, and by the vigorous movements of the child's limbs. Meeh | calls attention to the fact that the movements of the child are produced chiefly by the extension of the lower extremities, and argues that these movements aid to a greater extent in changing the presentation of the child when the breech occupies the lower seg- ment of the uterus, because of the solid resistance offered by the bony pelvic ring, while in head-presentations the pressure of the extremities against the elastic fundus is in the rule unavailing to effect any con- siderable changes of position. * ScHROEDER, Schwang., Geb. u.

In head or breech presenta- tions, the back of the child is most commonly turned to the left, which, hence, is termed the first position. The back turned to the right is known as the second position, and occurs with much less frequency. In the first position the back is usually directed somewhat ante- riorly, while in the second position it is turned rather to the rear. T.n shoulder-presentations the back is usually directed to the front. Changes of position are frequent in pregnancy, and take place, Avhen other influences do not prevent, in obedience to laws of gravity. When the woman stands erect, the axis of the uterus is continuous with the axis of the superior strait of the pelvis, and forms with the horizon an angle of thirty-five degrees. The uterus does not occupy exactly the median line, but lies more to the right. It is also twisted slightly upon its axis, so that the left lateral portion is directed somewhat to the front. In the upright position, therefore, the anterior wall of the uterus not only forms an inclined plane, but one, too, with a down- ward drop toward the left side. Now, if these relations be borne in mind, it w\l be readily seen that the child, resting upon the inclined plane furnished by the anterior wall, with its right shoulder directed downward, must, if left to itself, turn with its back to the left side of the uterus. In the recumbent posture, the axis of the uterus forms with the horizon an angle of thirty degrees, and the downward slope is to the right side. The child, now resting upon the inclined plane furnished I^j;; the posterior wall, with its right shoulder directed down- ward, would naturally turn with its back to the right side of the uterus. These considerations are not purely theoretical, as, when the conditions have been such as to allow the foetus latitude of movement, the changes indicated in the fetal position followed changes in the attitude of the mother.* The position of the child has heretofore been determined by that of the child's head when, after the advent of labor, the head has been brought within reach of the examining fingers. Sutugin, however, maintains that, during pregancy, if the patient be examined in the re- cumbent position, the back is nearly always turned to the rear whether it be situated to the right or the left of the spinal column. Changes of position by posterior rotation he believes are not uncommon. f * HiJxixG, Scanzoni's Beitrage, Bd. vii, p. 99. t Sutugin, Beitrage zum Mechanismus der Geburt bri SchOdellagen.

Changes in the sexual apparatus and neighboring organs. — Changes in the uterus. — Explanation of apparent shortening of cervix. — Changes in the vagina, vulva, abdomen, navel, breasts, nipple. — Functional disturbances of bladder. — Constipation. — CEdema. — Changes effected in the entire organism. Changes occuruixg ix the Sexual Apparatus axd Neighboring Organs. The pregnant state is signalized by the nutritive energy imparted by the fecundated ovum to the generative organs and to the viscera in their vicinity. The uterus, from, the inception of pregnancy, increases in vascu- larity. Its mucous membrane becomes soft and thickened. The mus- cular fibers are increased seven to eleven times in length, and three to five times in width. During the first five months new muscular fibers are developed, especially upon the inner layer of the uterus. The delicate connective-tissue processes between the muscular fibers become more abundant, and toward the termination of pregnancy display distinct fibrillar. The vessels increase in number, length, and circumference. The arteries, as we have noticed, assume a spiral course, and in places communicate directly with the veins. The veins are dilated, and form, especially in the placental region, wide-meshed networks. The walls of the veins are intimately united with the muscitlar walls of the uterus, and form, when divided, open-mouthed canals. The lymphatics, starting from the spongy tissues of the lin- ing mucous membrane, traverse the muscular structures, and are gathered up by abundant plexuses, which are distributed especially over the fundus and sides of the womb. The nerves increase in length and thickness, and grow inward toward the uterine cavity. Upon the inner surface of the uterus ganglia may be observed.* The ganglion cervicale, Avhich measures in the non-pregnant condition three fourths of an inch in length and half an inch in width, is now an inch and a half in breadth, and possesses a length of two inches. * Spiegelberg, Handbuch der Geburtshiilfe, p. 50. ^^ PHYSIOLOGY OF PKEGNANCY. These textural changes are accompanied by an enormous increase in the vohime of the uterus. The weight of the latter in the virgin state is about an ounce, while toward the end of pregnancy it weighs in the neighborhood of two pounds. The increase in the bulk of the uterus is progressive. The following table, by Arthur Farre,* furnishes ap- proximate measurements for the different months of pregnancy : Length. Width. End of 3d month 4^-5 inches, 4 inclies. 4th " 5th 6th 7th 8th 9th 5i-6 ' 5 6 -7 " 5J 8 -9 " 6i 10 ' 7i 11 ' 8 12 ' 9 According to Levret, the surface of the virgin uterus msasures six- teen square inches, while that of the pregnant uterus at term measures three hundred and thirty-nine square inches. f The uterine cavity is stated by Krause to be enlarged five hundred and nineteen times. | The enlargement of the uterus is not due, in the beginning of pregnancy at least, to the pressure of the expanding ovum, for the same changes occur during the first four months in cases of extra- uterine pregnancy. In the latter months, however, a mechanical stretching is probable, as the walls become thinned and conform to the size of the ovum. At term, the walls are not of uniform thickness, but vary between one sixth and one fourth of an inch. In pregnancy the muscular fibers of the uterus, as has been shown by Ruge, Hofmeier, and others, are arranged in groups, which possess a lamellar structure, the individual layers pursuing a general direction from the peritoneal covering downward and inward toward the lining mucous membrane. The principal layers are in turn united by com- municating bundles, so that when separated from one another the spaces between them have a rhomboidal shape. Very nearly the same ap- pearances are obtained when the section is transverse or oblique as when made in a longitudinal direction. Over the larger portion of the uterine surface the peritonaeum is firmly adherent. Only at the lower segment, for a space varying from three to six centimetres, measured from the internal os, the peritoneal attachment is easily separable. According to Hofmeier,* the muscular plates in this division are loosely associated together, and the fibers of each lamella are intimately interwoven, crossing one another in every direction.

Y9 the body proper of the uterus there is a broad muscular layer, which ad- heres firmly to the peritoneal covering, the differentiation of the individual lamellae is more pronounced, the mus- cular fibers are arranged more in bun- dles, and, in general, form layers which correspond to a greater degree to the longitudinal and transverse axes of the uterus. The uterine artery, after first sup- plying a branch to the cervix, runs up along the side of the uterus, and gives off the first important branch to the body of the uterus at the point where the peritonaeum firmly adheres to the muscular walls. The lower segment, therefore, receives no important vessels, and is characterized by a low degree of vascularity.* With the growth of the gravid uterus, the peritoneal coat is put upon the stretch, and, in places, a thicken- ing of the serous membrane lakes place by the formation of new tissue ele- ments. At the same time the folds of the broad lip:aments gradually sepa- rate, so that toward the end of preg- nancy the ovaries and Fallopian tubes are in close contact with the uterus. The growth of the uterus is con- fined chiefly to the body, the cervix participating only to a slight extent. In the early months, the increase is rather in the antero-posterior and lat- eral diameters than in the longitudinal diameter. As a consequence, in the rule, it is not until the fourth month that the fundus can be felt through the abdominal walls above the sym- physis pubis. In these earlier months the normal anteflexion of the uterus is increased by the weight of the cor- * HoFMEiER, Beitrage zur Anatomie der Schwangeren und Kreissenden Uterus, p. 33. O.i. O.e.

During the last two weeks, however, the uterus sinks somewhat into the pelvic cavity. At the same time the fundus of the uterus sinks downward and forward, so as to stand about three inches beneath the lower extremity of the sternum. In the upright posture the uterus, in advanced pregnancy, rests upon the anterior abdominal walls. As, in the intervals of contrac- tion, the uterus is a mere sac with fluid contents, it becomes flattened from front to rear, and the width increases at the expense of the dis- tance from the fundus to the symphysis pubis. In the horizontal position, in which the uterus rests upon the vertebral column, its length is, on the contrary, increased and its width diminisiied. In the upright position, the intestines occupy the space posterior to the uterus. In the dorsal position, the intestines lie chiefly upon the sides, but partly, too, in front of the uterus. During the first three months of pregnancy the pyriform shape of the uterus is preserved. During the succeeding three months, owing to the relative increase in the lateral and antero-posterior diameters, the body gradually assumes the appearance of a flattened spheroid. After the sixth month the longitudinal diameter again preponderates. As the dilatation of the uterus takes place more rapidly in its upper than in its lower segment, the cavity of the organ assumes, under normal conditions, an oval shape, with the narrow end pointing down- ward, corresponding to the ovoid shape of the foetus in head-presenta- tions. It was long taught and believed that this change of shape, occurring in the later months of pregnancy, was due to the gradual unfolding of the cervix uteri from above downward, which thus con- tributed to the enlargement of the uterine cavity. It is, however, probable that, with rare exceptions, the cervix uteri maintains its com- plete integrity up to the commencement of labor. The enlargement of the uterus, necessitated by the development of the foetus, results chiefly from the growth and distention of the fundus and posterior uterine wall. The cervix uteri participates in the hypertrophy of the entire uterus. Its development, however, is completed by the fourth month, and is the result not so much of increased growth or new formation of tissue elements as of the loosening of its structure and swelling from serous infiltration. This latter is the consequence of a hyperaemia of the cervix, which results from the passive relaxation and dilatation of the cervical vessels. It occasions a physiological softening of the tissues, which first manifests itself in those portions of the cervix where the least resistance is encountered, viz., beneath the mucous mem- brane beginning at the os externum, extending outward through the muscular structures of the vaginal portion, and afterward upward CHANGES IN THE MATERNAL ORGANISM BY PREGNANCY, si toward the os iuteruuin.* The follicles of the cervical mucous mem- brane furnish a thickened secretion, which fills the cervical canal, and forms what is known as the " mucous plug." Frequently the orifices of the follicles become occluded. The follicular sacs then fill with their own secretion, and project from the mucous surface as the ovules of Naboth. Erosions about the os externum are rarely absent in advanced pregnancy. With the advance of pregiumcy an apparent shortening of the cer- vix takes place, at first confined to the vaginal portion, but afterward involving the entire organ. The earlier explanation of this phenomenon, and one which still nK?ets with very general acceptance, assumes that, after the sixth month, a gradual unfolding of the cervix from above downward takes place, which contributes to the enlargement of the uterine cavity. In this manner space is provided in correspondence with the rapidly increasing growth of the foetus. The strength of this doctrine lay, in a great measure, in the seemingly confirmatory evidence afforded by digital explorations. In opposition to the current opinion, Stoltz, in his inaugural thesis, published in 182(!,f maintained that the internal os remained closed up to the last two weeks ])receding delivery, when, indeed, under the in- fluence of painless contractions, the effacement of the cervix, described by earlier writers, did in fact, at least in primipara?, take place. Stoltz explained the ai)jiarent shortening of the cervix as the result of a spindle-shaped dilatation of the cervical canal, causing an approxima- tion of the external and internal orifices. In 1859 Duncan;]; furnished corroborative evidence of the general correctness of Stoltz's view, by means of two dissections of uteri derived from women who died re- spectively in the seventh and eighth months of pregnancy. In these cases the length of the cervix uteri had undergone little or no change consequent upon pregnancy. Duncan, however, in common with Stoltz, admitted that, during the later days of gestation, incipient uterine contractions of a painless nature may lead to the opening of the internal os. In 1803 he showed that Stoltz's discovery had been anticipated by Weitbrecht in 1750.* In 1862 Professor I. E. Taylor, || of New York, stated, what is without doubt true in the majority of cases, that the cervix remained closed, and retained its entire length up to the very beginning of active labor. In evidence he offered the re- sults of four post-mortem examinations made upon women dying from * LoTT, Zur Anatomie und Physiologic des Cervix Uteri, Erlangen, 1872, pp. 35, 36. t Sur les dififerents etats du col de I'literus, niais principaleinent sur les change- ments que la gestation et raccoucheinent lui font eprouver, Strasbourg, 183G. t On the Cervix Uteri in Pregnancy, Edinburgh Med.

The bag of waters, in the form of a cylindrical sac two inches in diameter, protruded into the vagina. Both the cervical orifices were distinctly defined; the cervix was equally expanded tliroughout its entire extent ; and tlie head rested above the os inter- num. The cervix clearly formed no part of the uterine cavity, but served merely as a communicating passage between the uterus and vao-ina. Dr. Taylor has made some very interesting observations upon the action of tlie cervix during labor, using for the purpose a large (three to three and a half inch) cylindrical speculum, by means of which the entire process can be freely witnessed. In multiparous women he has seen the head descend during a pain so as to produce complete obliteration of the cervix, and then recede, leaving the latter with the same appearances as existed previous to labor, f While the non-shortening of the cervix has been fairly demon- strated, it is not so clear tluit the os internum remains closed in all cases up to the beginning of labor. Certainly there are rare excep- tions to the rule, Litzmann J reported a case in which the mem- branes were found, at the time of labor, attached to the cervical wall around the periphery of the os externum. In a few instances I have had an opportunity, during the last period of pregnancy, to deter- mine by touch the dilatation of the os internum. The cervix, how- ever, did not expand in such a way as to become continuous with the uterine cavity, but remained distinct and apart, preserving its inde- pendent existence. IIow far such a dilatation is due to painless labor it is impossible to say. Miiller * regards it rather as the result of the pressure of the head upon the softened cervix. I had once occasion to examine a multipara toward the end of gestation, to determine the question as to the safety of her making a railroad journey to a neigh- boring city. I found the head low, the cervix soft, and the os inter- num clearly dilated to the size of a dollar. Two weeks later I was called to see her in the early stage of labor, and found that, under the influence of the uterine contractions, the canal of the cervix had again closed. The apparent shortening of the cervix is unquestiona])ly due in part to the swelling, incident to pregnancy, of the vaginal mucous * Vide likewise the ease of Angus McDonald, in Edinburgh Med.

But, in addition, a noticeable differ- ence may be observed between cases in which the head occupies the pelvis and tliose in which it rests upon an iliac fossa. In the latter the cervix is found, both by the speculum and by the touch, to have pre- served its entire length. In the former, on the contrary, the anterior lip is often obliterated, while the length of the canal and the posterior cervical wall remain unchanged. In explanation of this phenomenon, it is to be borne in mind that in the upright position the uterus forms with the horizon an angle of thirty-five degrees. The weight of the ovum, resting upon the in- clined plane of the ixterus, increases the convexity of the anterior wall, and the head of the foetus, when it enters the pelvic cavity, does not fall directly upon the os internum, but somewhat in front, producing, Fig. 57.— B, borders of the cervical mucous membrane ; PI, placenta ; V, bladder : O.i., os in ternum ; O.e., os externum ; A a', apparent length of cervical canal on digital examination in accordance with the laws of gravity, a bulging of the anterior lower segment. TTpon vaginal examination the head is felt, therefore, low down, and covered by the uterine walls, while the cervix is drawn up- ward and backward by the retractor muscles, and is often reached with difficulty, because the finger, in passing to it, has first to make the circuit of the child's head. The bulging produced by the latter effaces the angle between the anterior lip and the vaginal wall, while the posterior lip remains unchanged. The canal of the cervix assumes g^ PHYSIOLOGY OF PREGNANCY. an oblique or nearly vertical direction, but when examined with care, with due regard to the physiological softening of its tissues, is found to have preserved its normal length. By pushing the head away from the cervix, or by placing the patient in the knee-elbow position, so as to allow the head to recede, the anterior lip resumes its normal dimen- sions.* Bandl (Ueber das Verhalten des Uterus und Cervix in der Schwangerschaft und wahrend der Geburt, 1876) has sought to prove that whereas, in point of fact, a portion of the cervix remains closed to the end of ])regnancv, a portion of the same does, as Roederer tauglit, contribute to the formation of the uterine cavity. In presenting his views to the Naturforscher-Versammlung at Hamburg, in 1876, Bandl stated that, upon examination of the familiar Braune section, made upon the cadaver of a parturient woman, he was struck with the impossi- bility that the cervix therein depicted, measuring eleven centimetres in front and ten centimetres posteriorly, could be the sliort narrow canal, from two to four centimetres long, observed by Miiller toward the end of gestation. As a rule, however, in case of the deep position of the ovum, or fetal head, above the constriction designated by Mtiller as the os internum, may be felt a second and much larger ring, which his subsequent investigations showed was the os internum proper. The lower constriction he termed, therefore, the spurious os internum, or the ring of Miiller. Owing to the fact that the walls of tlie canal between the upper and lower rings are much thinner than those of the uterine body, a well-defined ridge is felt, which has since been termed the.j u.ntr F RONTO MENTAL.

The fronto-mental diameter extends from the top of the forehead to the point of the chin ; the cervico-bregmatic, from the middle of the large fontanelle to the upper portion of the neck near the larynx. In furnishing standard measurements of the foregoing diameters it is of course understood that no two heads present precisely the same dimensions. As a rule, as shown by Sir J. Y. Simpson, the heads of boys are larger than those of girls. In selecting type-cases it will be re- membered too, that, owing to the plasticity of the head, in none are the diameters completely normal immediately after the transit through the generative passages. Unless, therefore, the child is delivered by Cesarean section, sufficient time should be allowed to elapse after de- livery before the measurements are made, to permit the head to return to its natural shape. Again, as in the measurements of the pelvis, the figures selected to represent the normal average should be such as admit of convenient recollection.

The circumference at the sub-occipito-bregmatic diameter is but thirteen inches. The Articulation of the Head with the Spinal Column.— The move- ments of the occiput upon the atlas are extremely limited, those of extension and flexion, which the head executes so readily, taking place for the most part in the articulations of the cervical vertebrae. Move- ments of rotation are performed at the articulation between the axis and the atlas In practice, the head can not be turned with safety to either side beyond a quarter of a circle, though, when rotation is per- formed slowly after delivery, it may sometimes be carried to such an extent as to enable the face to look directly backward. The insertion of the spinal column at a point nearer to the occipital than the frontal extremity of the child's head is of supreme importance in the further- ance of the mechanical processes of labor. It converts the head into a lever, consisting of two unequal portions. When the head, there- fore, encounters circular resistance in passing thi'ough the obstetric canal, pressure transmitted through the spinal column causes the de- scent of the occipital short end of the lever ; while the pressure upon the forehead from the side walls flexes the chin upon the thorax, the degree of flexion depending upon the size of the canal through which the transit is made.

The mechanism of labor— -i. e., the manner in which the foetus passes through the parturient canal— varies with the presentation. The presentations are classified, in the first place, with reference MECHANISM OF LABOR. ^09 to the position of the fcetus in relation to the axis of the uterus. In cases where the long diameter of the fretus coincides with that of the uterus, we have further to distinguish presentations of the head and presentations of the pelvic extremity. Head or cephalic presentations comprise those of the vertex, i. e., the portion lying between the two fontanelles, the brow, and the Jace^ Pelvic presentations oifer two varieties, viz., breech presentations and foot presentations. When the long diameter of the foetus crosses the axis of the uterus, there is produced a transverse, or, after the operation of uterine con- tractions, a shoulder presentation. Vei-tex, face, and pelvic presentations are included in the category of natural labors. Brow and shoulder presentations are termed unnat- ural, as, with few exceptions, they are not terminable except by the resources of the obstetric art. Vertex presentations alone are to be regarded as normal, as they only realize the mechanical conditions compatible with the highest degree of safety to both mother and child. In the following pages it is purposed to associate with the descrip- tions of the mechanism of labor, in the various presentations and posi- tions, an account of the means of diagnosis and the treatment suited to the special cases under consideration, instead of placing diagnosis, mechanism, and treatment in chapters distinct from one another. The writer believes, from long experience in teaching, that what is thus sacrificed in the way of systematic completeness is more than compen- sated by the clinical advantage of keeping in close proximity the prin- ciples of obstetric art and the rules of practice directly deducible from them. Precedence of description is given to the vertex presentation as representing the normal type of labor. , A'ertex Presentations. In 93,871 births, collected from private practice, Spiegelberg found that in over ninety-seven per cent the cranial vault presented,* The back of the child in utero is directed in about seventy per cent of cases to the left, and in thirty per cent to the right, side of the mother. The fronto-occipital diameter of the head measures four inches and a half. The diameters of the pelvic brim, after deducting the soft parts, are nearly as follows : Transverse diameter of brim 4f to 5 inches. Oblique " " 4f to 5 inches. Antero-posterior diameter of brim (minimum diameter about one third inch below the crista pubis) 4 inches. * Spiegelberg, Lehrbuch der Geburtshiilfc, p. 148. 170 LABOR. Thus it will be seen that the fronto-occipital diameter of the head may, at the brim, enter the pelvis without meeting with any special resistance in either the transverse or oblique diameters. In the conju- gate diameter, on the contrary, this is not possible. Transverse posi- tions, where the conditions are normal, are of very exceptional occur- rence, though they form the rule in flattened pelves. Tarnier * suggests that this infrequency is jDartially explicable on mechanical grounds. The long transverse diameter of the pelvis, he says, is, owing to the projection of the promontory, situated in a line consid- erably posterior to the point at which the sagittal suture normally meets the conjugate. When the head, therefore, enters the pelvis in a transverse direction with both parietal bones upon the same plane, the fronto-occipital diameter corresponds to a shortened chord subtending two points of the pelvic ring in front of the anatomical transverse diameter ; in point of fact, therefore, the latter, at the site of engage- ment, is less than either of the oblique diameters. In flattened j^elves this difficulty does not exist, as, in place of both parietal bones entering upon the same level, the posterior is turned toward the corresponding shoulder, the anterior dipping obliquely into the brim (lateral obliquity of Naegele), an arrangement by which the long diameter of the head is brought into correspondence with the long diameter of the pelvis. At the time when the sagittal suture is accessible, and it is possible to observe with correctness, the antero-posterior diameter of the head is found to approximate to one or the other of the pelvic oblique diam- eters. It is customary to classify the positions of the head with reference to the direction of the occiput. Most English authorities admit four varieties, viz. : The right occipito-anterior (occii>ito-dextra anterior, 0. D. A.), the right occipito-posterior (occipit*dextra posterior, 0. D. P.), the left occipito-anterior (occipito-lfeva anterior, 0. L. A.), the left oc- cipito-posterior (occipito-lgeva posterior, 0. L. P.). Naegele first called attention to the fact that the head approximates, in an overwhelming proportion of cases, to the right oblique diameter ; that, therefore, when directed to the left, the occiput is turned to the cotyloid cavity, and, when directed to the right, it looks toward the sacro-iliac synchondrosis. This peculiarity probably results from the fact that the uterus is usually rotated in such a way upon the spine that the right side inclines obliquely backward, while the left side is turned somewhat to the front. Naegele's observation is undoubtedly correct as regards the position of the head after labor has actually begun. Sutugin,f however, main- * Tarnier et Chantreuil, Traite de I'art des accouchements, p. 465. t SuTUGiN, Beitrage zum Mechanismus der Geburt bei Schadellagen, KHnischer Vortrage, No 310. MECHANISM OF LABOR. 171 tains that when the patient is examined in the recumbent position during pregnancy abdominal palpation sliovvs that, as a rule, the back, of the child, whether situated to the right or the left of the vertebral column, is turned somewhat posteriorly. At the beginning of labor the head, surrounded by the lower seg- ment of the uterus, is commonly found at the brim or resting upon ;in iliac fossa in multiparae, and below the brim, Avithin the pelvic cavity, in primiparae. The direction of the head, as regards its vertical axis, depends upon the degi-ee of resistance afforded by the contigu- ous uterine tissues. In the softened, relaxed condition often observ- able in multipara toward the close of pregnancy, the two fonta- nelles are not infrequently situated upon the same level. Where the lower uterine walls are firm and slope toward the os internum, the weight of the child's body, transmitted through the vertebral column, depresses the occiput. At the same time the sloping uterine walls, acting upon the frontal extremity of the child's head, direct the chin toward the thorax, thus producing a state of semi-flexion. The Nokmal Mechanism of Labor. The mechanism of labor in vertex presentations is usually described as consisting of a series of acts, termed respectively descent, flexion, rotation, external restitution, and expulsion of the trunk. A familiarity not with the names of the various acts, but the things the names represent, is essential to the judicious prosecution of the obstetric art. Descent and Flexion. — Descent and flexion go hand in hand, and should be associated in thought as they are in reality. It is evident, whenever the head encounters the resistance of the obstetric canal, the force transmitted through the spine to the foramen magnum will cause the descent of the occiput, and thus flexion will result. The degree of flexion, however, is proportioned to the extent of the action of the walls upon the frontal extremity of the head, and therefore is variable in different subjects and in different parts of the canal. The head enters the pelvis in the axis of the brim with the bi- parietal diameter very nearly parallel to the superior strait. This direc- tion it maintains until arrested by the curvature of the sacrum and by the floor of the pelvis. The descent of the head through the cervix is effected by the pressure of the uterus during contraction upon its entire contents. Even admitting the possibility of a certain amount of propulsive energy from the uterine walls through the trunk of the child to the head, it is necessarily of feeble force, as the flexibility of the spine and the smoothness of tlie breech prevent the latter from finding a proper point (Vappui against the vaulted fundus. 172 LABOR. In the transit of the head through the cervix the degree of flexion is governed by the amount of pressure exerted by the cervical ring upon the frontal portion. In some instances this suffices to render flexion complete — i. e., the chin sinks until arrested by contact with the chest ; whereas, as is most often the case in multipara?, the cervix may be so softened and dilatable as to aifect but slightly the direction of the occipi to-frontal diameter. Most frequently the maximum degree of flexion is occasioned by the convergence of the walls of the parturi- ent canal at the pelvic outlet. It is well for the beginner to keep con- stantly in mind that flexion is not in any sense an active movement. It is always a movement of accommodation, the end of which is the successive substitution of a shorter diameter for a previous longer one, so soon as the latter has encountered sufficient resistance to arrest its further progress. The mechaYiical advantages of flexion are obvious, when we recall that the average length of the sub-occipito-bregmatio Fig. 99.— Vertex presentation ; child surrounded by aiiuiiutic Huid. (Pinard.) or maximum diameter of the flexed head (3f inches) is three quarteis of an inch less than the occipito-frontal or maximum diameter of the head when midway between extension and flexion. Again, the maxi- mum circumference of the flexed head (thirteen inches) is 1| inch less than one measured about the extremities of the occipito-frontal diameter. These measurements, which are representative of the natural state, are, however, far from expressing the full extent of the ditfer- ences which exist after the plastic head has undergone the molding processes incident to labor. MECHANISxM OP LABOR. -^h^ A further advantage of flexion is thus described by Professor Pajot ; « The foetus, in its entirety, is to be regarded as a broken, vacillating rod, possessed of mobility at the articulation of the head and trunk • but a solid thus disposed presents conditions unfavorable to the trans- mission of a force acting principally upon one of its extremities; it follows, therefore, that previous to flexion the uterine action, pressing upon the pelvic extremity to promote the advance of the foetus, is lost in great measure in its passage from the trunk to the head by reason of the mobility of the latter ; but the cephalic extremity, once fixed upon the thorax, is most advaiitageously disposed to participate in the impulse communicated to the general mass of the foetus." * After the head is once released from the environment of the cer- vical canal, a slight movement of extension may follow, provided the resistance offered by the vagina is less than that of the cervix. In many cases, as has been stated, Avhere dilatation is complete at the time of rupture of the membranes, the head may pass through the cervix with scarcely any change in its direction, flexion taking place first when the head encounters the resistance of the sloping pelvic walls and the j^erineal floor. Rotation. — The head, as we have seen, follows the axis of the su- perior strait until arrested by the extremity of the sacrum and the perineal floor. As it nears the latter, the curvature of the sacrum ap- proximates the posterior Avail to the sagittal suture. Upon vaginal examination, the finger comes in contact with the anterior half of the heail as the presenting part. It is not, however, on that account to be assumed that the head is inclined laterally toward the posterior shoulder, though the sensation produced deceptively favors such a theory, t When the head has once reached the perineal floor, its further progress is associated with the most interesting of the mechanical acts of labor. The occiput, whether previously directed to the anterior or posterior extremity of an oblique diameter, turns forward under the arch of the pubes, until the sagittal suture occupies very nearly the antero-posterior diameter of the outlet. The utility of this movement is obvious. Owing to the inward slope of the side walls of the pelvis, the distance between the ischia is but 4^ inches, and between the spines 4 inches. If, in forceps operations, the head is dragged through the transverse diameter of the pelvis previous to rotation, it becomes flat- tened and lengthened in the direction of the trachelo-bregmatic diam- * Pajot, Dictionnaire encyclopedique des sciences medicales, t. i, p. 382, quoted by Tarnier et Chantreuil, p. 639. t With the apparent obliquity it is probable that a certain amount of real obliquity coexists. As, even in extreme flexion, the lateral movements of the head are not interfered with, it is hardly to be expected that the head, when arrested at the perineal floor, would continue to maintain a right line with the spine. 174 LABOR. eter, and the child's life, and the soft parts of the mother, are jeop ardized. When, however, rotation is completed, the bi-parietal diam- eter (3f inches), which is capable of snstaining a considerable degree of lateral compression, engages in the transverse diameter of the pel- vis ; at the same time the sub-occipito-bregmatic engages in the con- jugate diameter. The latter, though measuring but 3f inches, may be extended to 4^ inches by the pressing backward of the tip of the coccyx. The conditions for the forward rotation of the occiput are — 1. Flexion ; 2. Good labor-pains ; 3. A firm perinaeum. • In either of the occipito-anterior positions rotation is not diffi- cult to understand. The convergent anterior inclined planes furnish smooth surfaces upon which the occiput glides downward and forward Fig. 100.— Figure illustrating the mecliauisiu ut Ictbor in occipito-anterior deliveries. (.After Sctiultze. ) to the front. The rigid ischial spines direct the forehead to the sacro- sciatic ligaments, which determine the backward movement corre- sponding to that of the occiput in the front part of the pelvis.* * Prof. Henry G. Landis, in a most ingenious essay entitled How to use the Forceps, argues that, practically, the pelvis contains two canals, partially separate at the beginning and identical at their termination. The right canal is the one in which the right sacro-iliac articulation is found, and the left the one to which the left sacro-iliac articulation belongs. These canals converge from above down- ward, and are also mutually curved from before backward. Their direction is therefore spiral. The caliber of each canal is that of the fetal head ; therefore, the head may descend in either canal, and will follow a spiral course in so doing. MECHANISM OF LABOR. -^^^J^ Professor Pajot expresses the law which governs the rotation move- ments in the following terms: " When a solid body is contained within another, if the receptacle (eontenant) is the seat of alternations of move- ment and repose, and its surfaces are slippery and but slightly angular, the contained body will tend increasingly to accommodate its form and dimensions to the form and capacity of the receptacle." * In occipito-posterior positions, the rotation of the occiput forward is, at the first glance, a puzzling phenomenon, as the inclined planes of the pelvis, the ischial spines, and the law of accommodation, pre- viously invoked by way of explanation, should determine the rotation of the occiput not to the front but to the sacral cavity. The follow- ing experiment of Dubois, however, throws considerable light upon the principal conditions of success : " In a woman who had died a short time previous in child- bed, the uterus, which had remained flaccid and of large size, was opened to the cervical orifice, and held by aids in a suitable position above the superior strait ; the foetus of the woman was then placed in the soft and dilated uterine orifice in the right occipito-posterior position. Several pupil-midwives, pushing the fretus from above, readily caused it to enter the cavity of tiie pelvis ; much greater effort was needed to make the head travel over the peri- na?um and clear the vulva ; but it was not without astonishment that we saw, in three successive attempts, that when the head had traversed the external genital organs, the occiput had turned to the right ante- rior position, while the face had turned to the left and to tne rear ; in a word, rotation had taken place as in natural labor. We repeated the experiment a fourth time, but as the head cleared the vulva the occi- put remained posterior. Then we took a dead-born foetus of the pre- vious night, but of much larger size than the preceding ; we placed it in the same conditions as the first, and twice in succession witnessed the head clear the vulva after having executed the movement of rota- tion. Upon the third and following essays, delivery was accomplished without the occurrence of rotation ; thus the movement only ceased after the perina?um and vulva had lost the resistance which had made it necessary, or, at least, had been the provoking cause of its accom- plishment." f This interesting experiment shows that it is unnecessary to assume a rotation force in the uterus itself. A certain amount of light is thrown upon the action of the perineal floor by the clinical fact tbat it is always the most dependent portion of the presenting part which ro- tates to the front. A moment's reflection will show that rotation, therefore, takes place in such a direction that the sloping surface of the child's head is brought into correspondence with the downward slope of the perinseum. Thus it sometimes happens, in occipito-pos- * Martel, De raccommodation en obstetrique, vide introduction, f Ibid., quotation, p. 93. 176 LABOR. terior positions, that moderate extension occurs, so that the large fon- tanelle is felt below the plane of the small one. In this case, the head rests with its entire length upon the perineal floor ; its movements are of necessity restrained within narrow limits; and, if extension persists, the pressure of the opposing ischio-pubic ramus directs the forehead under the arch of the pubes. When, however, the head is well flexed it no longer corresponds to the perineal plane. The oc- ciput then glides downward, and is projected forward by the elastic pelvic floor until the anterior parietal boss is forced between the ischio-pubic rami. As the occipital end of the flexed head descends downward and forward toward the pubic arch, the frontal ex- tremity encounters the resistance of the pelvic wall near the ileo-pectineal eminence. If the pressure upon the head were in all parts equal, no further progress would now be possible. But it is not equal. The backward press- ure applied to the frontal portion of the head is exerted upon the long end of a lever, and works, therefore, at a greater mechanical advantage than that directed against the occiput.* At the same time, if the anterior wall be divided by a line drawn on a level with the lower margin of the sym- physis, we find that in the superior division the general pelvic pressure di- minishes from before backward, while below the line indicated, owing to the open space afforded by the pubic arch in front, pressure diminishes from behind forward. Now, in accordance with the mechanical principle that when a body is sub- jected to varying pressures the movement will take place in the direc- tion of the least pressure,f we find that the frontal portion, which lies above the sub-pubic plane, turns backward, while the occiput, which lies below, turns under the arch of the pubis. It must not be supposed, in imagining the results of rotation, that the movement continues until exact coincidence of the sagittal suture and the conjugate is reached. Leishman endeavored to measure the * Tarnier et Chantreuil, Traite de I'art des accouchements, p. 644. t Stephenson, On the Mechanism of Labor, Obstet. Jour, of Gr.

He found that in left occipital positions the cord crossed the lambdoidal suture about an inch to the right of the small fontanelle, and thence extended forward to the middle of the opposite orbit, intersecting the median line at or near the anterior fontanelle.* In emerging from the pelvis, the two tubera parietalia do not pass out at the same time. In place of this, the head rolls upon its side, so that in left occipital positions the presentation is formed by the upper and posterior part of the right parietal bone, and in right occipital posi- tions by the corresponding territory upon the left parietal bone. Extension. — As the head clears the inferior strait it distends the perina3um, and converts it into a groove, which directs the occiput toward the vaginal orifice. With the descent of the head the peri- ngeum lengthens ; between the pains the perina?um retracts, and the head recedes. A gradual softening results from the continuance of this play, and, with diminished resistance from the perinaeum, the oc- ciput descends along the anterior pelvic wall, the trunk enters the cavity, and the neck finds support against the os pubis. Flexion con- tinues until the occiput engages between the pubic rami. When the resistance of the anterior bony wall is no longer encountered, the sur- face of the child's head glides forward upon the perinaeum, as upon an inclined plane, and describes a circle beneath the pelvic arch, of which the sub-occipito-bregmatic diameter forms the radius. The extension of the head, which is an essential feature of the fore- going movement, is the resultant of two forces, derived, first, from the uterus, second, from the pelvic floor. The uterine action is transmitted in the axis of the superior strait. With the occiput fixed beneath the pubic arch and the neck resting against the inner surface of the pubes, the propulsive force is exjjeuded upon the frontal extremity of the head, and this causes the separation of the chin from the thorax. So soon as the forehead passes the apex of the sacrum, the recoil of the coccyx and the elastic perinaeum drives the fronto-occipital diameter forward to the vulva, which now looks in a nearly vertical direction. When the bi-parietal diameter has once passed the vaginal orifice, the perinaeum rapidly retracts, and, as it glides over the face, the occiput is thrown sharply and rapidly upward against the pubes. External Rotation.— After the birth of the head, the face, no longer supported by the perinaeum, sinks toward the anal region. At the same time, or w^ith the recurrence of a pain, the head makes a quartor- * Leishman, The Mechanism of Parturition, p. 84.

This movement is partly a restitution of the head to its normal direction, and partly is due to a corresponding rotation of the shoulders in the pelvic cavity. To understand the mechanism of external rotation it must be borne in mind that, in the movement of rotation, performed by the head in its transit through the pelvic canal, the trunk participates to a diminished extent only. Thus, Schatz * found, in the frozen section made by Braune through the ca- daver of a woman who died in the second stage of labor, where the head had originally occupied the right occipito-posterior position, that the deviation between the pelvic extremity and the head was measured by an angle of thirty degrees, and between the head and trunk, on a line with the shoulders, by an angle of thirteen degrees. After the release of the head from the vulva the torsion ceases, and the fetal parts re- sume their natural relations to one another. The head, therefore, turns slightly to the side, as it accommodates itself to the direction of the shoulders. This first movement is termed " restitution," and is much less marked in occipito-anterior than in occipito-posterior positions. The shoulders assume an obhque position, until, encountering the sloping pelvic planes, the anterior shoulder rotates forward, and the bis-acromial diameter approximates to the antero-jiosterior diameter of the outlet. The internal rotation of the shoulders usually takes place suddenly, and is accompanied by the corresponding movement of the child's head. Excessive rotation is sometimes observed. Thus, the shoulders, in place of turning to the antero-postorior diameter, may continue in movement until they occupy the oblique diameter of the opposing side, the posterior shoulder coming to the front. This necessarily causes faulty external rotation of the head. It occurs most frequently in occipito-posterior positions, f Expulsion of the Trunk. — After rotation, the anterior shoulder passes under the arch of the pubes ; the trunk, as it is driven down from above, becomes bent laterally, and the posterior shoulder glides forward upon the perineum to the commissure of the vulva; both shoulders then make the exit from the vaginal canal simultaneously. In the delivery of the shoulders the bis-acromial diameter is usually somewhat oblique. The expulsion of the trunk, owing to the previous dilatation of the passage, follows with rapidity ; the body executes a spiral movement until the hips engage at the outlet; during the birth of the pelvis, however, the bis-iliac diameter rotates so as to approximate to the line extending from the coccyx to the pubes. * Schatz, Arch. f.

(Vertex Presentation.) In the proper performance of the various mechanical acts of labor, it is necessary that the diameters of the fetal head approximate to those of the canal through which it has to pass. A very large pelvis, or a very small head, may become disturbing factors by leading to imperfect flexion and rotation. In either case, with a lax perinfpum and gaping vulva, the head may be born in any of the diameters of the pelvis. Head-births in either an oblique or transverse diameter are, however, extremely rare. They are attended with unusual difficultv, as the occiput has to traverse a longer course than when directed forward under the pubic arch. The most important of the irregular forms results from the rota- tion of the occiput, in occipito-posterior positions, backward into the hollow of the sacrum.* The chief condition of its production is a partial extension of the head, the forehead then turning anteriorly, in accordance with the law that the most dependent portion of the pre- senting part is moved to the front.

If the rotation is incomplete, the anterior parietal, or adja- cent frontal bones, are seen at the rima pudendi ; and, as the frontal portion is born, the occiput sweeps forward to the perineal commissure. After the occiput makes its exit, the neck rests upon the perineum, while the head swings backward, describing a circle, of which the sub- occipito-bregmatic diameter forms the radius. Delivery in these cases is apt to be tedious, and often demands the aid of forceps. Configuration of the Head in Vertex Presentations. During labor the various head diameters of the foetus undergo ex- tensive modification as they are subjected to the resistance of the par- turient canal. Of these, the most important is the diminution of the sub-occipito-bregmatic, the occipito-frontal, and the bi-temporal diam- eters, with compensatory elongation taking place in a line running from the chin to a point in the sagittal suture situated between the apex of the occipital bone and the large fontanelle (maximum diame- ter of Budin). The plastic changes mentioned are rendered possible by the presence of the fontanelles, the width of the sutures, the plia- FiG. 103.— Outlines showing difference between head of child at birth (1) and four days subse- quent to delivery (2).

These movements are rendered possible MECHANISM OF LABOR. ISl by the depression of both frontal and occipital bones beneath the adjacent borders of the parietal bones; at the same time, the dragging thus exerted upon the latter, front and rear, increases the curve of the cranial vault along the line of the sagittal suture. The sharpness of the bend at the summit of the curve is more or less pronounced, ac- cording to the rigidity of the channel through which the head passes. In cases of bii'th with the occiput to the rear, the head is often drawn out to a great length, the occiput forming an almost vertical line with the neck and shoulders, while in front the forehead and parietal bones slope upward to the vertex in nearly the same plane. The contour of the head is still further modified by the formation of the caput succedaneura, or scalp-tumor, a swelling developing upon the portion of the presenting part, which is subjected to diminished pressure from the obstetric canal, and which in consequence be- comes the seat of venous hyperasmia, oedema, and extravasation. The formation of the tumor is usually preceded by wrinkling of the scalp, indicative of the stronger compres- sion above. It may be produced within the cervical canal, but is then usually of insig- nificant size and of small practical impor- tance. Indeed, it may even form previous to rupture of the membranes in cases where the separation of the bag of waters from the con- tents of the uterine cavity is complete, and where, we have seen, the water-pressure below the line of cervical contact with the head is less than the intra-uterine pressure above. Usually, however, it is developed after the head reaches the pelvic floor, at the outlet of the vagina, the situation upon the scalp often enabling one subsequent to delivery to diagnose the position the head had occupied within the pelvic canal.* A voluminous scalp-tumor is, as a rule, the result of compression from the bony canal, and forms, therefore, in normal pelves, below the narrowing of the inferior strait.

According to Dessaut,* the scalp-tumor is usually of larger size when situated upon the anterior surface of the head, partly because of the greater laxity of the tissues, and partly because of the longer dura- tion of labor when the forehead is directed to the front. Its length may vary from a half -inch to two inches or more. In extreme cases, where the labor has been prolonged, there is sometimes found, asso- ciated with the scalp-tumor, a separation of both the periosteum and the dura mater from the underlying segment of the cranium.

Under favorable conditions the back presents upon one side of the uterus a broad, palpable surface without distinctive bony projec- tions. The outline of the dorsal surface may be rendered more distinct by downward pressure exerted over the fundus upon the breech of the child. The position of the child is determined — 1. By the fetal heart, which, except in face-presentations, is heard most distinctly over the dorsal surface ; 2. By the direction of the feet, which are situated upon the abdominal side of t'.ie child. Upon examination made per vagiuam the head is felt as a hard, round, smooth body, characterized by the sutures and fontanelles, and sufficiently large to till the space of the pelvis. Before the rupture of the membranes, investigations should be conducted in the intervals be- tween the pains, i. e., vv^hile the membranes are lax and depressible. If the head is high, and retreats before the examining finger, it should be steadied by counter-pressure applied to the fundus uteri through the abdominal walls. The sutures and fontanelles are best made out after rupture of the membranes. In passing the extremity of the index-finger backward over the cranium toward the sacrum, the sagittal suture is usually en- countered. At the extremities of the sagittal suture the two fonta- nelles are perceived, distinguishable from one another by the differences in size and shape. In exceptional cases the extreme compression of the bones of the skull may render the large fontanelle scarcely recog- nizable ; in others, again, the presence of membranous spaces in the line of the sagittal suture, fissures at the apex of the occipital bone, or the existence of ossa triquetra near the site of the small fontanelle, may cause perplexity, and lead to errors in the diagnosis of head positions. It is therefore well to bear in mind, as special marks of distinction, that the small fontanelle furnishes the meeting-point of three sutures, while four sutures meet at the large fontanelle. The sagittal suture pursues a straight course, forming a right angle with the coronal and an obtuse angle with the lambda suture. An- teriorly it is continuous with the frontal suture; posteriorly it ends abruptly at the occipital bone. The lambda suture, which is the only one liable to be mistaken for the preceding, is distinguished by its curvilinear direction, by the greater thickness of the parietal borders, and by the depression of the occipital beneath the parietal bones. When the sutures are masked by the presence of a large scalp- tumor, it is still possible in most cases to diagnose the position by pushing the finger up behind the symphysis pubis and feeling for the ear. jg^ LABOR.

It is not a very common anomaly, having occurred, according to Pinard, 320 times in 81,711 confinements at the Maternitc in Paris, or, in round numbers, once in 250 cases.* Causes. — The causes of face presentations are imperfectly known. Clinical observation has, however, succeeded in connecting the exten- sion of the head in the pelvic canal with a variety of predisposing con- ditions. To Ahlfeld \ we are indebted for a collection of associated events derived from a careful analysis of well-observed cases. From these, the following are selected because of their more palpable con- nection with the phenomenon in question : Separation of the chin from the chest, resultiiig from congenital en- largement of the thyroid gland ; from increased size of the chest in- terfering with flexion ; from stricture of the cervix about the neck of the child, the uterine walls adding to the circumference of the thorax ; from the mobility of the foetus, either because of its small size or from excess of amniotic fluid ; from oblique positions of the child and of the uterus, especially in cases of rapid escape of the amniotic fluid ; and from coiling of the cord around tlie head of the foetus, Ilecker J lays great stress upon the shape of the child's head, and has endeavored to establish a connection between face presentations and unusual length of the occiput. To be sure, after birth in face presentations the hind- head is often found to nearly equal in length the anterior portion, arid it is easy to see that, were such the case at the beginning of labor, the question of extension or flexion would always be in suspense ; but, in most cases, the shape is the effect rather than the cause of the presen- tation. Still, Hecker and others have reported instances where the elongation, instead of proving temporary, persisted after delivery, and therefore, it was fair to assume, had existed as a pre-natal condition. * Charpentier, Contributions a I'etude des presentations de la face, p. 15. t Ahlfeld, Die Entstehung der Stirn- und Gesichtslagen. X Hecker, Ueber die Schadelform bei Gesichtslagen. MECHANISM OP LABOR. 18^ The resistance encountered by the occiput, which converts partial into complete extension of the head, may be furnished by either the uterine or the pelvic walls. Most writers ascribe great importance to oblique positions of the foetus and of the uterus in the etiology of face presentations. In mul- tiparas, the former are not uncommon during pregnancy, the head then resting upon an iliac fossa. As a rule, however, the first pains straighten the foetus, the narrowing of the uterus in its transverse diameter serving to press the breech toward the fundus and the head into the pelvis. So long as the back of the child is directed downward, the rectification would inevitably be followed by head-flexion. When, however, the back is turned toward the fundus, and the change to the vertical attitude is not readily effected, the pressure of the adjacent uterine wall may, during contraction, act in a special degree upon the occiput, and direct it backward toward the neck, while the forehead sinks forward into the brim of the j^elvis. This movement is often temporary, and with the descent of the child the resistance encoun- tered by the forehead may exceed that met with from the occiput, and thus in the end flexion may follow in the ordinary manner. If, how- ever, the extension continues, a point is finally reached at which the propelling force is exerted specially in the direction of the chin, now converted into the short end of the lever, and the face presentation becomes complete. In the same way, extension may be produced when the occiput is arrested at the linea iunominata, an accident most likely to occur in transverse narrowing of the pelvis, and, again, in flattened pelves when the bi-parietal diameter is arrested by the contracted con- jugate. The mechanism of head- flexion may likewise be interfered with by a prolapsed extremity encroaching upon the pelvic space. In lateral obliquity of the uterus, the curvature of the uterine canal favors the production of face presentations when the back of the child conforms to the convexity of the lower surface, as the propelling force, which is transmitted in the axis of the uterus, then passes along the anterior aspect of the foetus, and increases the tendency of the fore- head to descend. While in vertex presentations the left dorsal positions are nearly three times as frequent as the right, in face presentations the differ- ence is very small.* Both Duncan f and Schroeder J ascribe this rela- * Statistics are as yet not sufficiently numerous to determine the question as to which position actually occurs most frequently. Dubois and Desormeaux (Diction- naire, in thirty volumes, p. 364) reported eighty-five cases. Of these, in forty-five the chin was turned to the right, while in thirty-eight it was directed to the left. Dr. A. Walther (Winckel's Berichte, Bd. iii. p. 212) reported from the Dresden Lying-in Institute thirty-one cases. Of these, the chin was turned to the left twenty-one times, to the right ten times. t Duncan, Edinburgh Obstet. Trans., vol. ii, p. 108.

Alilfeld * mentions further that it is not infrequent for extension to take place within the pelvic cavity, the arrest of the occiput result- ing from an unusual projection of the spines of the ischia. The Mechanism of Face Presentations. As in vertex presentations, the dorsum of the child may be turned to the right or to the left side. The position of the face is usually designated by the direction of the chin. We distinguish, therefore : 0'. ture may be classified under three headings, viz. : 1. Those designed to check the exit of the head before the fullest expansion has been secured, and to prevent expulsion during the acme of a pain, when the borders of the orifice are most rigid. 2. Measures which impart an upward movement to the head, with a view of making all unoccupied space beneath the arch of the pubes available. 3. Measures which favor expulsion during the interval between the pains, or at least after the acme has subsided. In ordinary cases Hohl's method, recommended by Olshausen,* has rendered me excellent service. It consists in applying the support not to the perinasum but to the presenting part. To this end the thumb should be applied anteriorly to the occiput, and the index and middle fingers posteriorly upon that portion of the head which lies nearest to the commissure. The unconstrained position of the hand enables the operator to exercise effective pressure in the direction of the vagina, while the posterior fingers favor the rotation of the head under the pubic arch. The patient should at the same time be directed * Olshausen, loc. cit., p. 366. 212 LABOR. not to hold her breath during the pains, except when they are weak and powerless. Where the impulse to bear down is irresistible, chloro- form should be given to annul the excessive reflex irritability. Under the most skillful management laceration is liable to occur, unless the physician is able to control the action of the auxiliary expulsive forces. So soon as the bi-parietal diameter passes the tense border of the vulva the perineum retracts rapidly over the face, and the expulsion of the head is completed. It is during this period that laceration is most apt to occur. This danger is, however, greatly lessened if the head is made to issue through the orifice after the pain has subsided, and when the soft parts are in a relaxed and dilatable condition. To accomplish this, in many instances where the resistance to be overcome is slight, it is sufficient for the woman to hold her breath during an interval between the pains, and voluntarily call into play all the mus- cles of expiration. In the larger proportion of cases, however, these efforts are futile, because of the comparatively feeble motor force brought into action. An excellent method of manual delivery we owe to Eitgen,* which consists in lifting the head upward and forward through the vulva, between the pains, by pressure made with the tips of the fingers upon the perinifium behind the anus close to the extremity of the coccyx. Of course, the metliod is only available after the head has descended sufficiently for the pressure to be exerted upon the frontal region. Rectal expression has lately found warm advocates in Olshausen f and Ahlfeld.J The manoeuvre consists in passing two fingers into the rectum toward the close of the second stage of labor, and hooking them into the mouth or under the chin of the child through the thin recto-vaginal septum. By pressing the face forward and upward, the normal rotation of the head beneath the pubic arch can be effected, and delivery can be accomplished between the pains at the will of the operator. When rupture is felt to be imminent, mock-modesty should be dis- carded, and the parts imperiled should be unhesitatingly exposed to view. If, owing to its excessive elasticity, the occiput, in place of being directed forward to the vulva by the perineum, distends the latter so that central perforation threatens, the hand should be applied in such a way as to give direct support to the stretched tissues and to guide the head upward to the outlet. If, . on the other hand, the danger arises from defective elasticity, the physician, standing to the right of the patient, with his face toward the foot of the bed, should * Olshausen, Ueber Daramverletzung und Daii^raschutz, Volkmann's Samm- lung., No. 41, p. 369. f See Ahlfeld, Das Dammschutz Verfahren nach Ritgen, Arch. f.

CONDUCT OF NORMAL LABOR. 213 pass the left hand between lier thiglis and press the head upward and inward, during each pain, Avith the thumb and two fingers, as previ- ously described. At the same time, the movement of extension, should it threaten danger to the parts, should be hindered by pressing back- ward upon the frontal region, through the perineum, with the disen- gaged hand. Dr. Goodell* recommends hooking two fingers into the anus and drawing the perina?um forward during a pain, to remove the strain from the thinned border of the vulva, and to promote the elasticity of the tissues. Merkerttschiantz advocates the emplojTnent of bilateral pressure upon the periuffum during the pains to diminish the tension in the median line where rupture usually occurs. To accomplish this the patient lies upon her back with her knees moderately separated. The physician sits to the right of the patient. The right hand is then placed beneath the right thigh, with the thumb and the fingers respectively applied to points on the right and left of the perinaeum. The points selected should correspond as nearly as possible to the region where the strain is the greatest. During a pain the thumb and fingers should be employed to press the perineal tissues from the sides toward the cen- ter. When the presenting part begins to distend the vulva, the left hand should be placed with the ulnar border over the mons veneris, and with the thumb and fingers resi^ectively applied to the right and left labia. As the frfenulum is put upon the stretch, the middle finger and the thumb should guard by lateral pressure a point in the perinseum about half an inch from the anterior border. This point should likewise be sustained at the same time from below by the thumb and fingers of the right hand. Merkerttschiantz f reports over 110 cases treated by this method without a single perineal laceration. More recently a plan which is the same in principle has been recommended by Dr. T. J. McGillicuddy, of this city.^ Fasbender* places the patient upon the left side; then, standing behind her, he seizes the head between the index and middle fingers of the right hand, applied to the occiput, and the thumb thrust as far into the rectum as possible. By this manoeuvre the head is held under complete control, the rectal wall harrlly affecting the grip in any ap- preciable manner. During a pain the progression and extension of the head are readily prevented. During the interval between the pains, by pressure with the thumb through the rectum and the poste- rior portion of the perinaeum, the head can be pressed forward and out- ward at the will of the operator. Between pains, I have been in the habit, in cases of rigidity, of alternately drawing the chin downward through the rectum until the head distends the perinaeum, and then allowing it to recede. It is as- * Goodell, Am. Jour, of the Med. Sci., January, 1871. f Merkerttschiantz, Arch. f. Gynaek., vol. xxvl, p. 327, 1885. X Vide Am. Jour. Obst., Dec., 1889, p. 1341. * Fasbender, Ztschr. f.

Of course it should be discontinued the moment contraction begins, and care should be taken to effect delivery after uterine action has subsided. "With judicious management the number of unavoidable lacerations can be restricted to a small proportion of cases. Still, there are indi- vidual peculiarities which Avill now and then render abortive the best prophylactic measures. In this. category I have already alluded to a primitive lack of development of the maternal parts, to unusual size of the child's head, and to the excessive rigidity of the perineum in primiparffi, especially after the thirtieth year. -In addition, should be mentioned cases where the pubic arch is diminished by the approxi- mation of the pubic rami, or where the tissues have been rendered friable from chronic oedema, from a varicose condition of the veins, from condylomata, from syphilitic sores, or from inflammatory infil- tration consequent ui)on undue jjrolougation of the second stage of labor. Lacerations are more frequent in occipito-posterior positions, and in the delivery of the after-coming head, where hasty extraction is demanded in tlie interest of the child. When, in the judgment of the physician, rupture of the perina^um seems inevitable, he is justified in making lateral incisions through the vulva to relieve the strain upon the recto-vaginal septum. To this operation tlie term episiotomy is applied. By it not only is the danger of deep laceration through the sphincter ani prevented, but, owing to their eligible position, the wounds themselves are capable of closing spon- taneously ; Avhereas, when laceration follows the raphe, the retraction of the transversi perinaii muscles causes a gaping to take place which inter- feres with immediate union. As, however, every wounded surface is a source of danger in childbed, episiotomy should never be performed so long as hope exists of otherwise preserving the perinaeum. It is essentially the operation of young practitioners, the occasions for its employment diminishing in frequency with increasing experience. The chief resistance encountered by the head is not at the thin border of the vulva, but is furnished by a narrow ring situated half an inch above, and composed of the constrictor cunni, the transversi perina^i, and sometimes of the levator ani muscles. Incisions should be made during a pain, Avhen the ring becomes tense and rigid, and is easily recognized with the finger. As it is not desirable that the head should be driven suddenly through the vulva during the act of operating, the time selected for performing episiotomy should be at the commence- ment or close of a contraction. The division of the rigid fibers may be accomplished by means of a blunt-pointed bistoury, or a pair of angular scissors. So far as practicable, the incisions should be con- fined to the vagina, and should not exceed three quarters of an inch CONDUCT OF NORMAL LABOR. 215 in length. In cases where the head is on the eve of expulsion, the bistoury may be introduced flat between it and the vagina, half an inch anterior to the commissure, and the section made from within outward. Care, however, should be taken at the same time to avoid severino- the external skin by drawing it us far back as possible.* In central per- foration it is best to divide the band left attached to the vulva, as its preservation is of no advantage. The Delivery of the Shoulders.— After the expulsion of the head, mucus should be wiped from the mouth and nose, and cleared from the throat with the finger should laryngeal rales indicate an embar- rassment of the respiration. If the cord is found coiled around the neck, it should be loosened by drawing upon the placental end until the shoulders can pass readily tlirough the loop. Should this be found impossible, either because the cord is unusually short, or because it is wound several times around the body, a ligature should be applied, the cord should be cut between the ligature and the placenta, and de- livery should be hastened by manual efforts, f In the majority of cases the shoulders are expelled spontaneously. Still, it is a good plan to expedite the descent by pressure made with the left hand at the fundus of the uterus. Care must be taken lest the lower shoulder convert a slight tear in the perinjeum into an ex- tensive laceration. The right hand should therefore be applied to the perineum in such a way as to lift the shoulder upward, and at the same time furnish a bridge over which it can glide in its movement forward. Sometimes after the j^assage of the head a deep vaginal laceration co- exists with an intact condition of the external parts. The shoulder then tears through the skin, and a complete rupture ensues. Olshau- sen recommends, in cases where rupture is imminent, to turn the shoulders so that they clear the vulva in an oblique or transverse diameter. If, after birth of the head, the child does not breath, and asphyxia threatens, the j^hysician should rub the uterus with the hand through the abdominal wall, to excite a pain, during which he should urge the patient to press down, and thus aid expulsion. The most common hindrance to delivery consists in an arrest of the upper shoulder be- neath the pubes. Usually its release is readily effected by seizing the sides of the head with the two hands and drawing directly downward. It is rarely necessary to raise the head subsequently, or to hook the finger into the armpit to extract the posterior shoulder. Tying the Cord.— When the cord is torn across, as sometimes hap- pens in street-births, no hemorrhage takes place from the lacerated * Olshausen, loc. cit., pp. 372, 373. t Tarnier recommends dividing^ the cord and then compressing the proximal end between the thumb and the ind'ex^finger. The proximal end is uistinguisheC by the spouting of the two umbilical arteries. 216 LABOR. vessels. Of course, this occurrence deprives the physician of the power of choosing the point at which the division sliall be made. As it is desirable, for the sake of convenience, to sever the cord about two inches from the navel, it is the custom in all civilized countries to cut it with scissors, and to prevent hemorrhage by the application of a ligature. Almost any material may be employed for the latter purpose, though nothing is so handy as the narrow flat bobbin which most nurses keep in readiness. Dr. Craig, of Jersey City, recommends the use of an clastic ligature as a security against haemorrhage. The ligature should be applied tightly, and the cut surface should subse- quently be examined once or twice by the physician before leaving, to make sure that the arteries are sufficiently compressed to prevent oozing from taking place. The cord should be held in the hollow of the hand at the time of its division, to avoid the possibility of including ac- cidentally any portion of the child between the blades of the scissors. Commonly two ligatures are applied, and the cord is severed between them, though the question of one or two ligatures is, excei^t in twin pregnancies, of trifling importance. In practice it is very desirable that the physician should understand the physiological difference between the effects of the early and those of the late application of the ligature. The custom as regards this point has been by no means uniform. The ancients deferred the liga- ture until after the expulsion of the placenta. Mauriceau, Clement, and Deventer followed the same plan, but employed artificial expe- dients to complete the third stage of labor rapidly.* The common practice at the present day is to tie the cord immediately after the birth of the child. Still, there have not been wanting in recent times warning voices against precipitate action. Naegele advised wait- ing until the pulsation of the cord had ceased ; Braun f first describes the changes from the fetal to the post-natal circulation, and then says : " This stupendous process should be taken into consideration in the treatment of every case of labor, and because of it the cord should never be severed or tied so long as pronounced pulsations can be felt near the navel." Stoltz I noticed that " after the child has respired * BuDiN, A. quel moment doit-on operer la ligature du cordon ombilical ? Publi- cations (lu Progres Medical, 1876. t Braun, Lehrbuch der Geburtshiilfe, p. 192. X Stoltz, art. Accouchement naturel, Nouveau Dictionnaire, p. 283. So. too, WurrE wrote, in 1773 : " The common method of tying and cutting the navel- string the instant the child is born is likewise one of those errors in practice that has nothing to plead in its favor but custom. Can it be supposed that this im- portant event, this great change which takes place in the lungs, the heart, and the liver, from the state of a foetus kept alive by the umbilical cord to that state when life can not be carried on without respiration, whereby the lungs must be fully ex- panded with air. and the whole mass of bloofl, instead of one fourth part, be cir- culated through them, the ductus venosus, foramen ovale, ductus arteriosus, and the I CONDUCT OF NORMAL LABOR. 9^^ well division of the cord is followed by an insignificant loss of blood, while after immediate section blood escapes in abundance." Winkler,* from anatomical observation alone, recommended not to tie the cord until the expulsion of the placenta, or at least until the cord had be- come pale and had ceased to pulsate, giving as his reason that by delay a certain quantity of blood would pass from the placenta to the child, and tliat every plus is a gain to the child, which would increase its powers of resistance. He finally expressed it as almost his belief that the practice recommended would tend to diminish the familiar loss of weight in the new-born during the first days of existence. In 1875, Budin, at that time interne at the Maternite of Paris, undertook the following experiments at the suggestion of Professor Tarnier : In one series, the cord was tied immediately after tlie birth of the child, and the blood which escaped from the placental extremity was measured ; in the other, tlie quantity of blood was determined ia cases where the cord was not tied until several minutes after delivery. By a comparison of the results thus obtained, he found that the aver- age amount of placental blood was three ounces greater in the first than in the second series of experiments.! Welcker estimated the entire quantity of the blood in the infant at one nineteenth the weight of the body, which would amount, in a child of seven pounds, to six ounces. To tie the cord immediately after birth would therefore be equivalent to robbing the child of three ounces of blood which would otherwise pass into its circulation. This startling result has in the main been abundantly confirmed by subsequent observers. Two years later (18TT), Schiicking, extending Budin's experiments by weighing the cliild at birth and then observing the changes that took place up to the time of the cessation of the placental circulation, found that the child gained from one to three ounces in Aveight by delay. It is cer- tain that these amounts do not represent the entire increase, as a portion necessarily escapes observation in the interval that must elapse before the weight can be ascertained. There is a difference of opinion as to the mechanism by which the umbilical arteries and veins must all be closed, and the mode of circulation in the principal vessels entirely altered — is it possible that this wonderful alteration in the human machine should be properly brought about in one instant of time, and at the will of a bystander i Let us but leave the afifair to Nature and watch her operations, and it will soon appear that she stands not in need of our feeble as- sistance, but will do the work herself at a proper time and in a better manner. In a few minutes the lungs will be gradually expanded, and the great alterations in the heart and blood-vessels will take place. As soon as this is perfectly done the circulation in the navel-string will cease of itself, and then if it be cut no hjpraoi- rhage will ensue from either end. . . ."

Ac- cording to Budin, the principal factor in the accomplishment of the result is thoracic aspiration. With the first breath, the afflux of blood to the lungs develops a " negative pressure " in the vessels of the larger circulation, so that a suction force is exerted upon the placental blood, which continues until the equilibrium is restored. To tie the cord prematurely, therefore, is to cut off from the child a supply of blood for which the establishment of the pulmonary circulation had created a physiological need. Schiickiug,* on the contrary, maintains that, after the first inspira- tion, thoracic expansion ceases to operate as an active force, and that the main agent which drives the blood from the placenta through the umbilical vein is the compression exerted by the retraction, and, at intervals, by the contractions of the uterus. The difference in the theoretical standpoint of these two observers is of practical importance, for, if the movement of blood to the child results from thoracic aspiration, the quantity which enters its circula- tion will not exceed its requirements ; while, if the movement is due to uterine compression, the question arises as to whether the forcible transfusion thus accomplished is compatible with the child's safety and welfare. The ultimate decision will depend partly upon experi- mental and partly upon clinical observations. Provisionally, the case stands as follows : The manometric observations of Ribemont f show that the pressure in the umbilical arteries is uniformly greater than that in the umbilical vein ; during a series of deep inspirations and expirations tlie blood in the umbilical vein is subject to marked oscil- lations; after the pulsations of the cord have ceased, the uterine con- tractions alone are insufficient to propel the placental blood through the umbilical vein to the infant. Again, Budin (discussion upon Ribemont's. paper), in a breech-delivery, compressed the cord at the vulva as far as possible from the navel ; at birth, the vein was dis- tended with blood, but with the first inspiration it was instantly emptied. Thoracic aspiration does, therefore, exist as an operative force. On the other hand, Schiicking found that when the placenta was rapidly expelled by Crede's method, so as to remove it from the influence of uterine retraction, the pressure in the vein was slightly lessened, and the total amount of blood transferred to the infant was greatly restricted. According to the clinical observations of Budin, Ribemont, and Schiicking, infants which have had the benefit of late ligation of the cord are red, vigorous, and active, whereas those in which the cord * ScHucKiNG, Zur Physiologie der Nachgeburtsperiode, Berl. klin.

OUNDUOT OF NORMAL LABO£. 211) is tied early are apt to be pale and apathetic. Hofmeier,* Ribemont, Badin, and Zweifel f have shown that the loss of weight wliich occurs in the first few days following confinement is less in amount and of shorter duration when the cord is not tied until after the pulsations have ceased. There appear to be no harmful results to the child growino- out of the practice of late ligation. Porak, indeed, reports two cases of dai-k vomiting, two of mel^ua, and two with sanguineous discharges from the vagina, which he is convinced were the result of the practice; but the extensive trial to which it has since been subjected in the principal lying-in institutions of the Continent have sufficiently demonstrated that it is exempt from danger. In late ligation, the amount of blood retained in the placenta and the increase in the weight of the child differ materially in different eases I — a difference which seems to indicate that, so long as the placen- tal circulation is left undisturbed, the amount of blood passing to the child will be measured by its needs. In a case of Illing's,* on the other hand, after the placenta had been expressed from the uterus, its contents and that of the cord were forcibly squeezed into the circula- tion of the child, and death followed from overdistention of the heart. Porak and Georg Violet | claim that there is a special predisposition to icterus in children when the cord is tied after the placental circula- tion has ceased. Violet attributes the discoloration not to bile-pig- ment but to a rapid disintegration of the excess of blood-corpuscles. Helot, he says, found on the first day after the birth a difference of nine hundred thousand corpuscles to the cubic millimetre between cases of late and those of early ligation, while on the ninth day the difference fell to three hundred thousand. Others have failed to notice any characteristic icteric discoloration peculiar to late ligation. Neither Porak nor Violet attaches any pathological significance to the symptom. The outcome of the foregoing observations may fairly be stated as follows : 1. The cord should not be tied until the child has breathed vigor- ously a few times. When there is no occasion for haste arising out of the condition of the mother, it is safer to wait until the pulsations of the cord have ceased altogether. * Der Zeitpunkt der Abnabelung, etc., Ztschr. f.

From the excess of blood contained in the fetal portion of the placenta, the child receives into its system only the amount requisite to supply the needs created by the opening up of the pulmonary circulation. 3. Until further observations have been made, the practice of employing uterine expression previous to tying the cord is question- able. 4. In children born pale and anaemic, suffering at birth from syn- cope, late ligation furnishes an invaluable means of restoring the equi- librium of the fetal circulation. Management of the Third or Placextal Stage of Labor. The duties of the physician in the third stage are to guard against hfemorrhage, to promote uterine contractions, and to farther the ex- pulsion of the placenta. These objects are best fulfilled by manipula- tions through the abdominal walls. Tractions upon the cord should not be resorted to before the placenta has accomplished its descent into the vagina. The method of expressing the placenta by seizing the uterus through the abdominal coverings is associated indissolubly with the name of Crede, for, though the value of friction, of knead- ing, and compression, was appreciated, as their writings show, by Mau- riceau, Robert Wallace Johnson, Joseph Clarke, Busch, Mayer, and others,* it was Crede who, by in- dependent study, worked out the practical details of the manoeu- vre, and by his advocacy gained for the principle of placental ex- pression its present wide-spread acceptance. Crede's method consists es- sentially in applying at first light and afterward stronger friction to the fundus of the uterus until an energetic contraction is ob- tained ; at its height the uterus is grasped so that the fundus rests in the palm of the hand, compressed between the thumb and fingers. The exercise of circular compression forces the placenta from the uterus, or in case of failure the process may be repeated until the object is accomplished. Crede lays great stress * For historical references, vide Riol, Delivrance par expression, G. Masson, 1880 ; MuNDE, Obstetric Palpation, p. 103. Fig. 122.— Expression of the placenta. (Cred6.) CONDUCT OF NORMAL LABOR. 221 upon the avoidance of violence in the practice of his method. It is true that the expulsion of the placenta will, as a rule, occur spontane- ously. The unaided uterus is, however, liable to relax and become the source of hajniorrhage ; or, where the delivery does not take place speedily, it may, on the other hand, close down so as to imprison the placenta within its cavity. The great merit of Crede's method is that by maintaining retraction it prevents hasmorrhage, and by pro- moting speedy expulsion it guards against the dangers of retention. When systematically practiced, the bugbear known as adherent pla- centa is the rarest of accidents. The method is not difficult, and is devoid of danger. To be successful, however, expression should ])e employed only during the acme of a contraction, and the propulsive force should be directed from the fundus downward in the axis of the uterus. Crede in his earlier papers advocated the expression of the placenta as soon after the birth of the child as possible. It appears, however, from the observations of Schroeder and others, that in most cases the placenta spontaneously leaves the uterine cavity, either in whole or in part, within the first fifteen to twenty minutes after the birth of the cliild, and that the delay observable in so many cases left to the un- aided elforts of Nature occurs usually after the placenta has sunk into the lower uterine segment. For this reason it is a good rule, accepted of late by Crede, not to resort to external manipulations until at least fifteen minutes have exjjired. The evidence of the expulsion of the placenta is furnished to the operator by his feeling the anterior and posterior walls in contact with one another. By thei^ pressing the uterus downward in the axis of the brim it is usually possible to drive the placenta through the vagina and out of the valva. There is no objection, however, at this stage, in case of delay, to expedite delivery by drawing upon the cord downward and backward. When the placenta passes the vulva the uterus is often firmly contracted, and a considerable portion of the membranes are still within the uterine cavity. Hasty traction is then apt to tear off the retained part of the membranes. It is well, therefore, at this point to support the placenta until relaxation of the uterus has taken place, when the complete separation of the membranes is effected without endangering their integrity. There has been considerable discussion of late as to the true physi- ology of placental expulsion. Thus it has been maintained by Schultze that after the birth of the child the diminution of the placental area during a uterine contraction is followed by a central separation of the placenta from the uterine walls and by a bulging of the separated portion into the uterine cavity. The detachment takes place in the decidual layer ; the mouths of uterine vessels are consequently opened up, and blood is aspirated into the retro-placental cavity. As, in i)oint 222 LABOR. regular Fig. of fact, no uterine cavity exists during a contraction, Colm * modified the Schultze theory by assuming that the central separation takes place in fact as a consequence of uterine contraction, but that the hematoma follows upon the occurrence of uterine relaxation. The further separa- tion of the placenta from the center to- ward the periphery is either the result of the increase in the amount of the effused blood, or is effected during a contraction by the peripheral pressure exerted by the blood previously aspirated behind the pla- centa. According to Schultze, therefore, the placenta normally descends by its fetal surface into the vagina, and a certain amount of hnemorrhage is the concomitant of placental expulsion Dohrn,t accepting the views of Schultze, objects to Cred6, that by his metliod " a proc- ess which should develop naturally is disturbed by a comparativelj' brusque manipulation." As a result of hasty placental expression, he men- tioned as especially to be deprecated the tend- ency to retention of the membranes. Later, Ahlfeld I urged against the Cred6 method that it increased the cases of dangerous haemorrhage, that it favored retention of the membranes, and that, as a consequence of the latter accident, it created a disposition to puerperal fever. The evils depicted by Dohrn, and especially by Ahlfeld, of the results of manual expression of the placenta, were so entirely opposed to my own experience, that during the past ten years I have continued to follow, with slight modifications, the counsels of CYede, and remain uncon- vinced that they do not furnish the best practical solution of the safe manage- ment of the stage of labor. When skillfully performed, I know of no other obstetrical manoeuvre to which the terms cito tuto, etjucunde can be so properly applied. As to the alleged dangers of the method, my experience corresponds to that of Roemer,* of Zinstag,|| of Fehling,^ and of Cred6,0 whose comparative sta- * CoHX, Zur Physiologie und Diatetik der Naehgeburtsperiode, Ztschr. f.

CONDUCT OP NORMAL LABOR. 223 tistics show that Credo's method does not increase the quantity of blood lost either in the third stage or during the puerperium ; that, unless resorted to at too early a period, it does not conduce to retention of the membranes; and that, even if this accident should occur, it does not, with rigid antiseptic conduct of labor, enhance the risks of puerperal infection. In opposition to Schultze, Duucan maiutaius that when the mech- anism of placental delivery is not interfered with by premature trac- tions upon the cord, the placenta descends edgewise through the cervix, and its expulsion is effected with the loss of but a trifling amount of blood. Of course it is understood that traction upon the cord is of common occurrence during the birth of the child, and that in consequence the Schultze method of descent is frequently enough met with. But Zinstag furnishes us observations in one hundred and thirty cases in which the cord was divided when coiled around the neck of the child immediately after the birth of the head, and in other cases during the passage of the breech. When this precaution was taken the mechanism of Schultze occurred in nine cases only ; that of Duncan * with the placenta folded on the fetal surface in ninety-four cases; and in twenty-seven cases with the edge presenting but with the placenta folded upon the uterine surface, and with a certain amount of blood effused from the uterine sinuses between the folds and behind the membranes. As a matter of practical importance, it is well to remember that when extraction is attempted previous to descent by pulling upon the cord, the central portion of the placenta is dragged into the cervix, while the borders are inverted in such a way as to form a cup-like cavity. This disturbance of the normal mechanism not only increases the difficulty of delivering the placenta, but causes the latter to exer- cise a suction force which increases the haemorrhage, and at times even is capable of partially inverting the lax uterine walls. Now and then, where the occlusion of the cervix is complete, it may be found impos- sible to effect delivery without first introducing two fingers and hook- ing down the margin of the placenta, so as to allow air to pass above into the uterine cavity. * Matthews Duncan, Edinburgh Med. Jour., April, 1871. Fig. 124.— Showing normal de- scent of placenta. (Duncan.) 224 LABOR. Care of the Patient after Delivery. As the danger of haemorrhage does not always end with placental expulsion, the physician should be ready to sacrifice, even in simple cases, at least a half-hour to close observation ©f the subsequent be- havior of the uterus. The weight of the hand laid above the sym- physis pubis is usually sufficient to maintain a safe degree of retrac- tion. Should, however, the uterus become lax, and lose its outline, the physician should grasp it in his hand and knead it firmly until a con- traction is excited. In this way he not only guards against haemor- rhage, but, by preventing the formation of clots, he diminishes in mul- tiparae the severity of the after-pains. Most physicians seek additional security against haemorrhage by administering ergot, which, as is well known, favors tonic retraction of the uterus. To this there is no objection, provided the ergot be given subsequent to the expulsion of the placenta. When given, as is commonly done," at the time of the passage of the child's head, it is liable to produce its effect prematurely, and thus to give rise to hour- glass contraction. The rarity of the accident is no argument in favor of the popularity of the practice in the face of the serious complica- tion to which it is capable of giving rise. When the physician judges it is safe to suspend the prophylactic pressure upon the uterus, ho should see that all the soiled clothing be removed from beneath his patient, and that the nurse wash the genitalia gently but thoroughly. Nothing does so much to cause speedy disappearance of the soreness of the external parts as perfect cleanliness. In hospitals, a vaginal douche of warm carbolized water should be combined with external ablutions. The perinifium should then be carefully examined, and, if lacerations are discovered, the physician should make himself acquainted with their extent and importance. Without entering into a discussion at this place of the methods of repairing perineal tears, it is proper to state that, both as a means of preventing infection and of promoting speedy convalescence, it is wise, in all cases where the laceration extends to or nearly to the sphincter ani, to bring the torn surfaces together by means of sut- ures. The technique is simple, and immediate union is the rule, if the same care is employed with regard to cleanliness that is usual in gynaecological practice. Rarely, failures to obtain union may result from syphilis, or from lowered vitality of the tissues due to extreme prolongation of the second stage of labor. The application of the binder is one of those points in practice about which men of large experience entertain a difference of opinion. In my student days in the Ilopital des Cliniques in Paris the binder was dispensed with. A folded sheet was, however, laid across the abdomen, it having been found that a certain amount of pressure was CONDUCT OF NORMAL LABOR. 225 necessary for the comfort of tlie patient. This plan compelled her to lie upon her back, and thus had the disadvantage of restrictino- freedom of movement. Careful observation has failed, however, to show me a single good reason why the binder should be discarded. When properly applied, it adds greatly to the woman's comfort, and enables her to turn at will upon her side. My own preference is for a piece of unbleached muslin wide enough to reach below the hips. In adjusting the binder, the physician should place himself to the right of the woman ; he should seize the near end between the thumb and two fingers of the left hand, while with the right hand he draws the further portion smoothly over it. The two ends should then be held with the left hand, and the pins, which should preferably be of large size, should be inserted with the right. The process should begin below, and be followed upward at intervals of about two inches. These details are given because the writer remembers his own embarrassment arising from his inability to get information upon this trivial subject in the early days of his practice. Moreover, as many women are somewhat tenacious of having the binder first applied by the physician, to know how to do it with address is not an indifferent accomplishment. Many place a compress made of a folded towel above the symphysis pubis. This addition usually serves no better purpose than to displace the uterus to one side. The toilet of the patient is finally completed by laying a warm folded napkin at the vulva to receive the lochial dis- charge. An aseptic dressing to the external parts is, however, warmly to be recommended in private as well as in hospital practice. This con- sists after washing the genitals thoroughly with a bichloride solution (1 to 3,000), in powdering the parts with iodoform, and then applying iodoform or bichloride gauze. The dressings should be held in place by an oakum pad. A little attention to these details possesses the immense advantage of preventing decomposition of the lochia and of promoting the healing of external wounds. Anesthetics ix Midwifery. The value of anassthetics in certain irregularities of the labor- pains, in eclampsia, and in most midwifery operations, is no longer a matter of discussion. The benefits from their employment in such cases are palpable and beyond dispute. As to the right, however, of a woman to have her sufferings assuaged in ordinary normal labor, there is by no means unanimity of opinion. To be sure, the old objections raised in Sir James Simpson's day, that labor-pain is a salutary mani- festation of life-force, that anaesthesia gives rise to paralysis, to peri- tonitis, to puerperal mania, to haemorrhage, to pericardial adhesions, to indecencies of language and behavior, and that it contravenes the Word 15 226 LABOR. of God, are now known to be unfounded or imaginary. Still, there is no doubt that the vast majority of medical men refrain from the use of anesthetics in ordinary labor, either from vain apprehensions or because some incident in their practice has led them to suspect that, in spite of statistics, they are not devoid of objectionable or dangerous properties. In my own experience during the last sixteen years, there have been comparatively few cases in which I have not used chloroform or ether in some stage of labor. The result of my experience has been to make me a warm advocate of their wider employment on the one hand, while proclaiming the necessity of caution in their use upon the other. It seems to me that the hesitancy manifested regarding their general adoption is due, in large measure, to the fact that few practi- tioners give themselves the trouble to master the necessary modus operandi^ to study the limitations of their usefulness, or to learn the conditions of their safe administration. It should be steadfastly borne in mind that the giving of anaesthetics in labor is an art to be acquired — a very simple one, perhaps, but the practice of which admits of neither ignorance nor carelessness. As in ordinary surgical practice, auEesthetics are contra-indicated by organic affections of the heart and lungs. Except in the prolonged insensibility required for difficult ob- stetrical ojDerations, I think the preference should be accorded to chloroform rather than to ether. The former possesses the advan- tage of being more agreeable, more manageable, and more rapid in its action. Ansesthesia, not narcosis, is the object aimed at, and the dulling of the sensibility is much more readily effected by chloroform than by ether. As a rule, chloroform should not be administered during the first stage of labor, partly because of its tendency, when given at too early a period, to weaken the contractions of the uterus, and partly because protracted anesthesia has a tendency to impair the cardiac force. To this rule there are, however, numerous exceptions, to which we shall have occasion to revert in connection with the consideration of irregu- lar labor-pains. If the pains in the second stage are of feeble intensit)^ it is best to withhold the anesthetic; if of normal strength, chloroform may be given, but at first only in small doses and during the continuance of a pain. The anaesthetic should not be pushed to the stage of complete unconsciousness until the head begins to emerge at the vulva. Chloroform can be conveniently given upon a folded handkerchief. The latter should be held near to, but not in contact with, the respir- atory passages. The best diluent for chloroform, as was long ago stated by Sir James Simpson, is atmospheric air. If the handkerchief be laid directly across the nose, instant suspension of respiration may result. CONDUCT OF NORMAL LABOR. 227 A minor evil is tlie cutaneous irritation produced by placing the chloro- form in direct contact with the lips and mouth. At the beginning of each pain the patient should be directed to take a number of deep inspirations. During the acme of the pain the expiratory efforts which arc then called into play prevent the inhala- tion of any considerable amount of the anaesthetic. When the head presses upon the perinaeum, the handkerchief should be intrusted to the nurse, but the administration to the end should be directed and strictly supervised by the physician. When chloroform is first given, it is common for the pains to become weakened ; but this suspensive influence upon the uterus is usually temporary. Exceptionally, however, the weakness of the pains may continue, and render it necessary to withhold the anesthetic. In still rarer cases the pains remain inefficient after the antesthesia has subsided. On this account it seems to me certain that those who use chloroform habitually will find themselves compelled to resort to the forceps with somewhat increased frequency. A tardy labor, due to uterine inertia, will likewise call for additional vigilance during the stage of placental expulsion to forestall the occurrence of hemorrhage. The immunity enjoyed by women in childbirth against the accidents which sometimes occur from anaesthesia in surgical practice is not abso- lute, but dependent upon its cautious and intelligent administration. I once narrowly escaped losing a patient in the Bellevue Hospital, upon whom I designed to perform version, in consequence of my house phy- sician suddenly crowding a paper funnel containing a towel wet with chloroform over the respiratory passages. Chloroform should not be given in the third stage of labor. The relative safety of chloroform in parturition ceases with the birth of the child. x\fter delivery it favors the relaxation of the uterus and predis- poses to hEemorrhage. Moreover, after the uterus has been emptied there is always an increase of blood in the large vessels of the abdomen, and a corresponding recession of blood from the head. Xow, it is known that the quantity of chloroform which one day is perfectly tol- erated by an individual in health may prove fatal on the succeeding day, in case of the intervention of any considerable loss of blood. Cerebral anasmia, from any cause, increases the risk of anesthesia. In lengthy operations requiring prolonged anesthesia, ether, as has already been intimated, should be preferred to chloroform. 223 LABOR. CHAPTER XII. MULTIPLE PREGNANCIES AND THEIR MANAGEMENT Frequency.— Origin.— Varieties.— Auardia.— Weight.— Unequal develupment.— Su- perfetation.— Diagnosis.— Labor.— Presentations.— .Simultaneous entrance of both children into the pelvis.— Locking.— Prognosis.— Conduct of labor. The term midtiple pregnancy is used when more than one germ are simultaneously developed. Twins, the most common form, occur in the proportion of one to between eighty and ninety births ; triplets in about the proportion of one to seven thousand; quadruplets and quintuplets are of extreme rarity. No authentic example of over five children at a birth is on record. An instance of quintuplets I have once witnessed. In the Prussian statistics of Von Hemsbach and Veit based upon thirteen million births, the number of twin pregnancies amounted to 150,000. Of these, in 50,000 both children were boys ; in 46,000 both were girls ; and in 54,000 the children consisted of a boy and a girl. Twins may develop either from two distinct ova, discharged from the same or from distinct Graafian follicles, or may both originate from a single ovum. If two Graafian follicles rupture, the ovaries will offer two corpora lutea. In some instances a corpus luteum has been found in each ovary ; in others both are situated in the same ovary. In the case where twins develop from two ova, each foetus is con- tained in its own chorion. If the ova are imbedded in the decidua at sufficiently distant points, the placentae will be separate, and each ovum will have its distinct reflexa. If near one another, the placentas are often united at their borders, each, however, maintaining its independ- ent circulation. In some cases the two ova lie so close together that they are encircled by a common reflexa. When twins are developed from two centers contained in the same ovum, the placenta, the chorion, and reflexa are, of course, common to both. In most instances each foetus is contained in its own amnion. Occasionally, however, twins are furnished with but one amnion — a peculiarity which, in some cases at least, is not primary, but the re- sult of an absorption of the party-wall between two originally distinct cavities.* Twins from the same ovum are always of the same sex. Anasto- moses of greater or less extent exist between the placental vessels of the two embryos. The consequences of these communications are of the utmost importance, for, when extensive, the heart's action in one * Ahlfeld, Beitrage zur Lehre von den Zwillingen, Arch. f. Gynaek., Bd. vii, p. 281. MULTIPLE PREGNANCIES AND THEIR MANAGEMENT. 229 foetus counterbalances that of the other ; the stronger blood-current in the placenta pushes back the weaker one, at first impeding the circula- tion of the less favored fcetus, then arresting it, and finally causing it to reverse its direction. The heart atrophies, and an acardia is pro- duced, which is simply an appendage to the healthy foetus. The cir- culation in the acardia takes place as follows : Venous blood from the healthy foetus is conveyed by the umbilical arteries to the placenta ; the force of the fetal heart drives the stream through the communicating Fig. 125. - Twin placenta, sliowin^ arterial anastomosis. branches to the umbilical arteries of the less favored twin ; this force is, however, insufficient to carry the current to the upper parts of the body, which are, therefore, not developed. The favorable position of the lower extremities for receiving the blood from the umbilical vessels explains their continued though imperfect growth and development. The blood carried to the foetus by the umbilical arteries is returned by the umbilical vein. According to Ahlfeld,* a division may take place in the formative material contained within a single area germinativa. This division * Ahlfelp, Die Entstehung der Doppelbildung und der liomologen Zwillinge, Arch. f. Gynaek., Bd. ix, p. 196. 230 LABOR. may be complete, and thus produce separate twins inclosed in the same amnion, which not only are of the same sex, but bear to one another through life the most striking similarity as regards appear- ance, physical peculiarities, and both mental and moral characteris- I Fig. 126.— Author's case of acardia.

In a case of quadruplets * Schultze, on the other hand, contends that the double monsters are derived from the fusion of two embryos developed upon the blastodermic vesicle at points close to one another.

MULTIPLE PREGNANCIES AND TIIKIK MANAGEMENT. 231 reported by P. i\Inller,* two ova were simple, while the third contained two embryos. The children in the single ova were of the female while those in the double ovum Avere of the male sex. The average weight of the individual children in multiple preg- nancies is less than that of children born single. This is partly due to the frequency with v/hich the excessive distention of the uterus becomes the exciting cause of premature delivery, and partly to the obvious fact that the maternal organism is rarely capable of furnishing the nutritive material requisite for the complete growth of more than a single child. Twins often exhibit at birth a remarkable disparity as regards both size and development — a disparity unquestionably due to local condi- tions. A striking example of this is shown in a case related by Schultze.f One child, at the time of delivery, was nearly if not quite, mature, while the other presented the appearances of a six weeks' fcetus. As both ova were enveloped in the same reflexa, their develop- ment mast have begun at nearly the same time. Sometimes one foetus dies, and yields to the more fortunate brother the space and the nutritive material which would otherwise have fallen to his share. In such a case the ovum and the contained fa?tus may be compressed by the surviving twin, and be flattened against the uterine wall, giving rise to the so-called " foetus papyraceus " ; or it may degenerate into a mole ; or the aborted ovum may be exjselled, while the living foetus advances to the full term of gestation. Very rarely, where the twins are both living but have undergone unequal development, the stronger child may be delivered first, \\'hile the other remains in the uterus, and is born after weeks of delay, dur- ing which, under more favorable conditions, it makes good the defi- ciencies due to its retarded evolution. The most remarkable cases of this kind occur in the uterus duplex. Professor Fordyce Barker re- lated an instance in his practice where, in a double uterus, a mature living male child was born on the 10th of July, 1855, and on the 2.2d of September following the mother gave birth to a full-term living girl. Histories like the foregoing are often adduced in support of the theory of what is known as superfetation — a theory which supposes that, aftcx conception has once occurred, a second gestation may result from a subsequent coitus. That this is possible, if two ova are de- tached during the same menstrual period, seems to be established by authentic accounts of negro women giving birth to twins, showing the evidences of a paternity derived in one from the black and in the other from the white race. That impregnation can take place at two periods distant from one another must be regarded as an inadmissible * P MiJLLER, Eine Vierling's Geburt, Ztschr. f. Geburtsh. uiul Gynack.. IM. iii, p. 166. f SCHULTZE, loc. cit., p. 308. 232 LABOR. hypothesis, until physiologists shall succeed in demonstrating in a sin- gle instance, by the presence of corpora lutea of different ages, that ovulation ever occurs during pregnancy. Diagnosis. — The diagnosis of multii^le pregnancy is rarely to be made out with absolute certainty. Unusual dze of the uterus, with exaggeration of the syhiptoms which result from pressure, would nat- urally lead to inquiry on the part of the physician, as it is certain to excite uppreliensions in the mind of the pregnant female. (Size, how- ever, furnishes but an uncertain criterion, as it may be equally due to the presence of a very large child, or to an excess of amniotic fluid. More trustworthy information is to be obtained from palpation and auscultation. Thus the recognition of a number of distinct fetal parts and the exclusion of hydramnion would render tlie diagnosis of twin pregnancy probable. The outlining of two fetal heads at a distance from one another would make the diagnosis certain. When the fetal heart is heard at two remote points, and the sound is found to die away in the intervening space, it is justifiable to conclude that the sound at each point has a separate origin. If the two heart-beats are counted at the same time by different observers, and are found not to correspond in frequency, a twin pregnancy is established be- yond dispute. After the birth of the first child, the presence of the second is determined by the size and consistence of the uterus, and the perception of fetal parts both through the abdominal walls and tlie vagina. The recognition of triplets and quadruplets is, of course, attended with even greater difficulties than that of twins. Labor in Multiple Pregnancies.— We have already noticed the fre- quency of ])remature labor in multiple pregnancies. Of one hundred and ninety-two twin births reported by Reuss* from the AViirzburg clinic, fifty-one did not complete the full term of gestation. In one of these abortion resulted from small-pox, in another from syphilis, in two cases premature labor was induced artificially, in the others labor occurred spontaneously — in one instance at the seventh month, in the other in the ninth or tenth months. Twin labors are usually easy. The first child is delivered as in simple labors, and, except in faulty presentations, is followed shortly by the second. The interval varied, in seventy-four of Reuss's cases which terminated spontaneously, from five minutes to one and a half hour. In seventy-nine per cent the interval was less than an hour. As the stage of dilatation is completed at the time of the expulsion of the first twin, a protracted interval is occasioned purely by weakness and inefficiency of the pains. The placenta? are usually expelled after the birth of the second child ; now and then tlie placenta of the first child precedes the birth * Reuss, Znr Lehre von den Zwillingen, Arch. f. Gynaek., Bd. iv, p. 123. I MULTIPLE PREGNANCIES AND THEIR MANAGEMENT. 233 of the second ; again, the second child may not be born until after the delivery of its placenta. When the placenta are united, a portion may be torn off and expelled with the first child, while the remainder is not thrown off until after the birth of the second.* The placental stage is, owing to the relaxed state of the uterine walls, apt to be of longer duration than in simple labors, and calls for the exercise of special care to guard against the occurrence of hemorrhage. Fig. 127.— Twin pregnancy, both heads presenting. (Tarnier et Chantreuil.) Presentations in Twin Labors.— Spiegelberg f furnishes the follow- ing table, derived from 1,138 deliveries, of which 899 were taken from Kleinwiichter and 203 from Reuss : Both heads presenting 558, Head and breech presenting 361, Both pelvic presentations 98, Head and transver.se presentations. ... ... 71, Breech and transverse 46, Both transverse 4, or 49 per cent.

The transverse presentations are mostly secondary, consequent upon the roominess of the uterine cavity and the sudden escape of the amniotic fluid. Version is, of course, in such cases easily per- formed. The Simultaneous Entrance of Both Children into the Pelvis.— The consideration of the various complications to which this anomaly gives rise belongs to the domain of pathology. To avoid, however, needless repetitions, they may, for convenience' sake, be properly considered in the present connection. AVheu both children present at the brim previous to the rupture of the membranes, it usually happens that, with the escape of the amni- otic fluid, one of the twins descends into the pelvis, while the second glides to one side. The result is identical, whether the twins are con- tained in a single or in separate sacs. If interference is called for because of delay, the amnion, or one amnion in case there are two, should be ruptured, and the nearest presenting part brought into the pelvis, while the other is at the same time pushed out of the way. If -head and breech present, the head should preferably be allowed to descend first. It may happen, however, that after rupture both children may descend into the pelvis so close to one another as to hinder each the other in its further progression. This locking of the twins, as it is termed, may take place in one of two ways, viz. : 1. In double vertex presentations, delivery may be impeded by the pressing of the second head into the neck of the more advanced foetus, or, after the birth of the first head, the second may enter the pelvis and arrest the advance of the thorax. Obviously this difficulty could only arise in a case where both heads were of unusually small size. The diagnosis has rarely been made previous to the birth of the first head. The treatment consists in the artificial extraction of one head after the other, and then delivering the body of the first child. Cra- niotomy is usually not necessary. The prognosis as regards the chil- dren is extremely unfavorable. Eeimann * reports six cases in which the fate of the children was known. Of the six first-born, one sur- vived; of the six last-born, two survived. Reimann, in commenting on these figures, remarks : " The child whose head first enters the pel- vis is in great danger, because not only is its neck squeezed by the head of the second child, thereby producing cerebral hyperaemia, but its umbilical cord is exceedingly liable to be compressed by the body of the second child." ■ 2. When one child presents by the breech, the other by the vertex, the former, because of its smaller size, is apt to descend first into the pelvis. No difficulty is then experienced until the neck is born. In case, however, meantime the head of the second child has entered the * Reimans. Am. .Jour, of Obstet., 1877, vol. i. p. .58. MULTIPLE PREGNANCIES AND THEIR MANAGEMENT. 235 pelvis, further progress may be rendered impossible, a lock resulting either from the overlapping of the chins, or of the occipital portions of the two heads, or from the pressure of the face of one child into the neck beneath the occiput of the other. By lifting the body of the child, and introducing the half-hand into the vagina, the diagnosis is rendered easy. In a large, roomy pelvis, if the pains are good and the children small, spontaneous delivery may take place. In a number of cases of Fig. 128.— Twill pregnancy, head and breech presenting. (Tarnier et Chantreuil.) this kind which have been reported, the head of the second child was born first. In a few instances it has been found possible to push up the second head. Operative measures consist in applying the forceps and extracting the second head, and afterward, if necessary, the first. In case of failure, craniotomy remains as an ultimate resort. The first child is rarely born living. Of twenty-six children, the fate of which was ascertained by Reimann, only three survived. The prognosis of the second child is more favorable. Of twenty-nine cases, Reimann reports nineteen survivals. Xaturally, therefore, the perforation of 236 LABOR. the first head would be preferred, were the matter one purely of elec- tion, but the operation is very difficult, and does not remove the ob- stacle, for even the diminished head can not pass the one already occupying the pelvis.* In the cases so far reported, where decapita- tion of the first child has been performed, the operation has not proved successful in saving the life of the second. The possibility of one twin sitting astride the other, when trans- verse, requires mention, because of the perplexity that may arise as to the diagnosis, unless the hand is introduced into the lower segment of the uterus to determine the exact relations of the twins to one another. Prognosis. — The prognosis, both as regards the children and the mother, is much more unfavorable than in simple labors. Statistics on this point are valueless, as much depends upon the conduct of the physician. As regards the children, the increased mortality results from prematurity, from unequal development, and from the frequency of malpositions and malpresentations, requiring operative interference. As regards the mother, the mortality and susceptibility to puerperal diseases are augmented by the excessive distention of the uterus, the extent of the placental wound, the feebleness in many cases of uterine retraction after delivery, and by the operations which grow out of the anomalies to which labor in multiple pregnancies is subjected. Conduct of Labor in Multiple Pregnancies. — The management of multiple pregnancies does not dift'er essentially from that of ordinary labor. After the birth of the first child, the placental end of the cord should in all cases be tied, on account of the frequency with which anastomoses are found between the vessels of the placentae. A period of repose should then be allowed, to enable the uterus to retract down upon the remaining ovum. During the birth of the second child, every care should be taken to follow the uterus with the hand, and redoubled precautions should be observed against the occurrence of haemorrhage, to which the woman is exposed both on account of the large size of the placental wound and the disposition to relaxation. In case the second child presents by the shoulder, version by external manipulations alone is usually practicable. Expression should be em- ployed to force the placentae into the vagina. When both descend at once, if it is necessary to make tractions, both cords should be drawn upon, simultaneously or in alternation, to find which placenta is most easily removed. When one placenta follows the birth of the first child, it should be left untouched until the advent of the second. Vigilance after delivery should be long observed. We have already noticed that the length of time between the ex- pulsion of twins situated in separate membranes rarely exceeds an hour. When, therefore, there is a longer delay in the delivery of the * Reimann, ioc. cU.. p. 61. I MULTIPLE PREGNANCIES AND THEIR MANAGEMENT. 2?>T second child, measures should be employed to excite pains, and the membranes should be ruptured. In case of a premature child deliv- ered with its own placenta, cases of continued deVelopment, in utero, of the remaining child, would point to the policy of abstention. In instances where more than two children are contained in the uterus, the anomalies of position are more frequent, and the danger of hsemor- rhage is still further enhanced.* * Spiegelberu, Lehrbuch. pp. 206, 307. THE PUERPERAL STATE. CHAPTER XIII. THE PHYSIOLOGY AND 3IANAGEMENT OF CHILDBED. The puerperal state borders closely upon pathological conditions.— Post-parlum chill.— Temperature.— The pulse.— General functions.— Retention of urine.— Loss of weight.— Involution.— Separation of the decidua.— Closure of tlie sinuses.— The cervix.— The vagina.— Position of uterus.— After-pains.— The lochia.— The secretion of milk.— Anatomical considerations. — Milk-fever. — Composition of milk.— Diagnosis of the puerperal state.— The new-born in- fant.— Changes in circulation.— The navel.— Tumor upou the presenting part, —Digestion.— Skin.— Icterus. — Loss of weight. — Management of puerperal state.— Sleep.— Passing urine.— Visits of physician.— Washing the vagina.— Diet.— Laxatives.— Nursing.— Duration of lying-in period.— Care of new-born infant.— Bath.— Cord.— Nursing.— Wet-nurses.— Artificial feeding. The puerperal state occupies the border-land between health and disease. Though in a strict sense physiological, it otters a variety of conditions, as Schroeder * has pointed out, whicli at other times, and under other circumstances, would be regarded as pathological. Thus, the exfoliation of the decidua, and the copious serous transudation, with the abundant formation of young cells which accompanies the development of the new mucous membrane, would elsewhere be re- garded as characteristic features of catarrhal inflammation. The acute degeneration of the uterus presents a phenomenon which, when re- peated in any other organ of the body, would prove speedily fatal. The thrombus formation in the open placental vessels possesses no corresponding physiological analogue. Again, the torn vessels may lead to haemorrhage, while the traumata which even in normal labor result from parturition, the ease with which deleterious materials are absorbed by the wide lymphatic interspaces, the serous infiltration of the pelvic tissues, the exaggerated size of the lymphatics and veins, create a predisposition to innumerable forms of disease. The nicety of the balance between normal and morbid conditions renders it pecul- iarly necessary for the practitioner to make himself familiar with the physiological limits of the phenomena of childbed. Post-partum Chill. — The exertion of labor is followed by a sense of comfort and repose. Often, after the birth of the child, a chill sets in * Schroeder, Handbuch der Geburtsliiilfe, 6te Aufl., p. 216. THE PHYSIOLOGY AND MANAGEMENT OP CHILDBED. 239 of greater or less intensity, but of short duration, and of no prof^nostic importance. It is to be accounted for by the disturbance of the equilibrium between the internal temperature and that of the external surface. Thus, toward the end of labor, and for a short period sub- sequent to delivery, the loss of heat is increased by the evaporation from the lungs and skin and the cessation of muscular effort. This cooling process is, however, speedly arrested by the contraction of the cutaneous arterioles. During the period which intervenes until the external and internal temperatures rise to relatively equal levels, the l)atient experiences chilly sensations, or a distinct, well-defined chill* This phenomenon is more frequent in hypera^sthetic women and in those whose skins are bathed in profuse perspiration, especially where there has been some necessary exposure of the person during the ex- pulsion of the head or of the placenta. Under the influence of a warm, dry bed, the chill at once subsides. Temperature. — As a rule, it may be stated that the temperature range in normal childbed does not differ materially from that which prevails in non-puerperal conditions.f Still, a rise of temperature fol- lowing the parturient act, averaging one and a half degree in primipara? and one degree in multiparas, is not uncommon. This elevation may continue during the first six days, with, however, morning remissions and slight evening exacerbations. It is most pronounced in the first twelve hours, especially when they coincide with the normal evening increment. In the following days the highest point is usually reached at five in the afternoon, while the lowest temperature is found in the night hours between eleven and one. A sub-febrile temperature of 100^° has no prognostic significance. A temperature rise above 100^° is by no means incomjsatible with a generally satisfactory condition of the patient. Among the provoking causes of increased heat pro- duction may be reckoned prolonged labor, fecal impaction, mental excitement, the reaction of small wounds in the course of the geni- tal canal, and the disturbances attendant upon the establisliment of lactation. J The Pulse.— In contrast to the increase in the temperature, the pulse often exhibits a remarkable diminution in frequency, in perfectly norjnal cases ranging between sixty and seventy beats, but not unfre- quently dropping to a still lower level, and may even sink to less than forty pulsations in the minute. This slowing of the pulse is of favor- able prognostic import. It is known to be associated with diminished ■"• Fehling, Klin.

It is usually most marked on the second or third day, and does not appear to be specially influenced by the establishment of lactation. General Functions.— During the first week the skin is active and moist ; the patient is, therefore, sensitive to temperature changes, and is subject to profuse perspiration when warmly covered or during sleep. The appetite is lessened, the thirst is increased, the bowels are slug- gish, and the urine abundant. In spite of the light diet and repose in bed, the amount of urea eliminated is but slightly diminished. Sugar in the urine is observed at the time of the establishment of lac- tation. It disappears soon afterward, to reappear, however, whenever the milk production is in excess of its consumption.! The diabetes is, therefore, due to absorption. J Retention of Urine. — In the first day or two following confinement, retention of urine is a common occurrence. It results, according to Schroeder, from the increased capacity of the bladder following the re- moval of pressure from the gravid uterus. !Many women who suffer from retention when reclining are able to voluntarily urinate when raised to a sitting posture, probably because of the greater facility with which, in the latter case, the pressure of the lax abdominal parietes can be exerted upon the bladder. Loss of Weight. — Owing to the rapid retrograde changes in the pelvic organs, the discharges from the genital passage, the increased secretions of the skin and kidne3'S, combined with limited ingestion of food, the loss of weight in the first week amounts to from nine to ten pounds, or, roughly speaking, to about one twelfth the weight of the body.* Involution. — The processes by means of Avhich the uterus returns to its non-puerperal condition are inaugurated at the commencement of labor. During the rapidly following contractions of the uterus there is, on the one hand, waste of tissue substance, engendered by the work performed, while on the other, the compression of the nutrient vessels diminishes the supply of reparative material. As a result of this dis- turbed equilibrium, there ensues a fatty degeneration of the protoplasm of the muscle cells. This process continues after the expulsion of tlie ovum. At the same time, the individual muscular cells shorten and * Meyberg, Ueber die Pulse der Wochnerinnen, Arch. f.

Geburtsk., Bd. xix, p. 47. THE PHYSIOLOGY AND MANAGEMENT OF CHILDBED. 241 broaden, while transverse and longitudinal ridges form iipon them. In this way, and by the absorption of the superfluous protoplasm, the muscular cells are gradually reduced to normal dimensions. In from six to eight weeks the process described reaches its completion. The lochia then cease, and, in women who do not nurse, menstruation returns. Tlie view maintained by Hesclil, which long received the support of obstet- rical writers, was in effect that subsequent to labor the entire muscular tissue of the uterus underwent fatty degeneration, and that the oxidized products were gradually absorbed. Meantime, a new formation of muscular cells, beginning upon the periphery of the organ, about the fourth week, took the place of the old elements. In accordance with this view, it has been customary to state that witli the end of each pregnancy the old uterus was destroyed, and that a new organ was built up upon its ashes. KoUiker admitted a partial destruction and a partial new formation of muscle cells, but held that the greater number of the enormously enlarged cells of pregnancy did not entirely disappear. The view we have given is that defended originally by Luschka and Robin. In studies preparatory to his work on Caesarean section, Sanger was perplexed to see how union of cut surfaces could be secured by means of suture if the theory of simultaneous acute fatty degeneration should be proved correct. Careful observations made by him upon this point seem to settle the question in favor of the more conservative natural process. * Immediately after birth the uterus weighs upward of two pounds. The peritoneal surface is covered with transverse, oblique, and longi- tudinal ridges, and furrows corresponding to the direction of the un- derlying muscular bundles. In two days the weight falls to a pound and a half ; the uterus is seven to eight inches in length, and about four and a lialf inches broad ; the walls are from an inch to an inch and a half in thickness. At the end of a week the uterus weighs a pound, and is five to six and a half inches long. At the end of two weeks the weight is three fourths of a pound, the length five inches, and the walls hardly a half-inch in thickness. Of course, the indi- vidual variations from these averages are very great, f In six weeks the process usually reaches the end, though the uterus remains ever after somewhat larger and more rounded than in nulliparae— a change due chiefly to an increase of connective tissue. Repair of the Decidua.— With the expulsion of the ovum the outer portion of the decidua vera for the most part adheres closely to the reflexa, while the meshy portion, with the fundi of the glands, remains attached to the uterus. The adherent portion consists of empty areolar spaces, of gland septa, of lymphatic spaces and blood-vessels, while * Vide The Involution of the Muscular Tissue of the Puerperal Uterus, by Dr. M. Sanger, Annals of Gynjecology, Boston, July, 1888. f BoRNER, Ueber deri puerperalen Uterus ; Sinclair, Measurements of the Uter- ine Cavity, Trans, of the Am. Gynaec. Soc, vol. iv, p. 231. Ifi 242 THE PUERPERAL STATE. only the fundal extremities are liued with glandular epithelium.* As, however, the line of demarkation rarely takes place throughout the entire decidua at any fixed level, fragments of the outer, more com- pact layer may frequently be found here and there clinging to the inner surface of the residual membrane.f The uterine cavity is covered and in part filled with at first a bloody and subsequently a muco-sanguinolent fluid containing blood and mu- cus corpuscles, and decidua-cells in various stages of degeneration. At the end of a week the mucous membrane measures at most from a half to three quarters of a line in thickness ; the inner surface has become smoother from the disintegration and exfoliation of adherent shreds ; the glands, owing to diminished size of the uterus, are pressed closer together, and assume a more nearly perpendicular direction ; the gland-epithelium extends upward along the gland-walls to the surface of the membrane ; the interglandular sjjaces are filled with lymphoid cells, with blood-corpuscles, fat-granules, and epithelial cells, in a state of fatty degeneration. As the regenerative process goes on, fine capil- laries Avithout walls form in the interglandular substance, so that the latter jn'esents the appearance of granulation -tissue. By the third week these vessels of new formation stretch upward to the surface of the mucous membrane, and by the sixth week the development of the vas- cular network is complete. In the second week the lymphoid cells begin to dissolve, and thus the glands are brought into near contact with one another. Spindle-shaped cells of young connective tissue are formed between the glands in the second week, and with continued connective-tissue jjroliferation the flattened tubules arc drawn upward, and assume a perpendicular direction. The epithelial cells at the mouths of . the glands, which at first formed separate islets, approach one another as the glands assume their normal positions, and by act- ively multiplying spread from the circumference until they form a continuous lining to the wounded surface. As regards tlie principal features, the changes which take place at the placental site are the same as those described elsewhere Avithin the uterine cavity. Immediately after delivery, however, the surface pos- sesses an uneven aspect, with elevations where the septa of the serotina had penetrated between the placental cotyledons, and with intervening depressions. The mouths of the torn vessels are closed by thrombi, and large vessels are irregularly distributed beneath the attached resi- due of the mucous membrane. The process of regeneration at the placental site takes place somewhat more slowly than elsewhere within the uterus. * Leopold, Studien iiber die Uterusschleimhaut, etc., Arch. f.

THK PHYSIOLOGY A\I) MANAGEMENT OF CHILDBED. 9+3 Closure of the Sinuses.— Bv tlie eighth montli of pregnancy, as has been mentioned, a portion of the sinuses beneatli the placenta are oblit- erated by the emigration of giant-cells which cause coagulation of the blood circulating through them. After delivery, the blood stagnates in the intact vessels in such a way that at first the inner walls are covered with fibrin, while the center contains fresh red blood. The walls then thicken by proliferation of the endothelium, and lymph - and blood -corpuscles penetrate into the coagulated layer. Finally, the thrombus fills the entire vessel, spindle-shaped cells radiate from the endothelium, and with the development of young connective tissue a gradual shrinkage takes place, which, however, proceeds slowly, so that four to five months after birth the placental site is still distinguishable.* According to Eugehuann, pigmentary deposits in the tissue of the mucous membrane are almost conclusive evidence of recent delivery, as after menstruation they are not found, probably on account of the superficial chai'acter of the haemorrhage. The Cervix.— After delivery the cervix speedily resumes its normal size. At first it has a soft and pulpy feel. The os internum forms a resistant ring, which constitutes a well-defined boundary between the corpus and cervix uteri. This ring varies in size in different subjects, but is always sufficiently o])en to permit the introduction of two fingers. Beneath, the walls are thrown into transverse and longitudinal folds. The OS externum is usually torn, especially upon the sides, and the thickened labia roll outward. The length of the canal measures tAvo and three quarters inches and upward. At the end of twelve hours the distinction between the cervix and vagina is clearly marked, and the OS internum is so far closed that a certain amount of force is requisite to pass two fingers into the uterine cavity. The contraction of the OS internum renders the longitudinal folds more pronounced in the upper portion of the canal. From this time on, the involution of the cervix advances rapidly. At the end of twelve days the canal is shortened to an inch in length. As the longitudinal muscles contract, the plicas palmat* become distinct as transverse ridges. The longi- tudinal folds, Avith the exception of the anterior and posterior ridge which belong to the plic« palmate, disappear with the retrograde changes which take place in the mucous membrane. The os exter- num long remains patulous, and permits the finger to pass to the os internum for a period varying between the seventh and fourteenth days. The anterior lip is thicker than the posterior, and is frequently the seat of erosions and granulations. The involution of the vaginal * Leopold, Studien iiber die Uteriisschleimhaut. etc.. Arch. f.

The contraction and involution proceed more rap- idly at the introitus than above in the neighborhood of the fornix, though, owing to the presence of lacerations, it remains, with few exceptions, permanently wider than in women who have never borne children. Position of the Uterus.— Immediately after the expulsion of the placenta the contracted uterus is felt through the abdominal walls as a tirm, solid body, of a flattened, pyriform shape. When both hips are on the same level, and both bladder and rectum are empty, the uterus is found in the median line with the fundus between the symphysis and the navel. At the same time the Aveight of the body and the laxity of the abdominal walls lead to a moderate degree of anteflex- ion. Urine in the bladder and fa»ces in the rectum give rise to a cer- tain amount of lateral displacement, and now and then to a torsion of the uterus upon its long axis. As in pregnancy, the fundus of the uterus is thus generally, though not always, directed to the right, and the left border looks to the front. The mean elevation of the fundus above the symphysis is about four and one third inches, the width of the fundus is upward of four and a half inches, and the length of the entire uterine cavity, as measured by the sound, is in the neighborhood of six inches. The dimensions of the uterus are somewhat less in primiparae than in multiparae. A full bladder pushes the fundus upward, and increases the longitudinal diameter of the organ. Borner has observed an increase from this cause amounting to three and a half inches. A diminution in the size of the uterus is apparent in most cases in the course of the first twenty-four hours. An actual increase is either pathological, or due to the above-mentioned influence of the bladder. The diminution is most marked in the first twenty days, but afterward progresses at a slow rate. About tht tenth day the fundus sinks below the level of the symphysis pubis, and the posterior surface of the ante- fleeted uterus occupies the plane of the brim.f After-Pains. — The reduction of the uterus in the first few days of * LoTT, Zur Anatomie und Physiologie der Cervix Uteri, pp. 87 ei seq.

I THE PHYSIOLOGY AND MANAGEMENT OF ( IlllJ)i;i;i). 245 tlie childbed period is in the main the result of contractions, termed after-pains, resembling those of labor both as regards the hardenino- of the uterine walls perceptible through the abdominal coverings, and the nature of the dolorous sensations which they evoke. The after-pains stretch over a period varying from one to four days. Their duration and intensity are in inverse proportion to the duration and activity of the preceding labor. On this account they are more pronounced in multiparas, while they are often absent subsequent to a first delivery. They are intimately associated with the permanent retraction of the uterus, and are therefore to be regarded as a normal and favorable phenomenon. T'hey are especially prominent in cases of overdisten- tion of the uterus, as, for instance, in cases of twin pregnancies and hydramnios. Suckling the infant produces reflex contractions of a somewhat intense character. The Lochia. — 'I'he discharges from the genital passage consequent upon delivery are termed the lochia. At first the latter are composed of pure blood with coagula of fibrin, but after a few hours the wounded surface of the uterus furnishes an abundant exudation of a serous, alka- line fluid, which washes away in its descent the secretion from the cer- vix and the vaginal mucus. For the first two or three days the lochia are of a red color {lochia ri(brn) from the commingling of blood, while upon the third, fourth, and sometimes upon the fifth day, as the san- guineous elements diminish, they present a pale-red color (lochia serosa). As constituents, we find under the microscojie cervical and vaginal epi- thelium, blood and mucus corpuscles, bits of decidua, and sometimes shreds of membranes and of the placenta. The organic constituents consist of albumen, mucine, the saponified fats, and a variety of saline matters. From the fifth to the seventh or eighth day the discharge continues thin, but the blood-corj)uscles become less abundant, while there is an increase in leucocytes and fatty globules. In the second week the discharge becomes of a grayish- white or greenish-3^ellow color (lochia alba sen lactia), and of a creamy consistence. It contains chiefly leu- cocytes, young epithelial cells, spindle-shaped connective-tissue cells, fat-granules, free fat, and crystals of cholesterine. The reaction is neutral or acid. Gradually the discharge diminishes, becomes trans- parent, and finally assumes a normal appearance. The vaginal lochia in the rule are found to contain a variety of micro-organisms, such as the diplo- and strepto-cocci, rod bacteria, the trichomonas vaginalis, and sometimes gonococci. They vary greatly in quantity, and increase in abundance with the advance of the puerperal week. They are derived in part from germs present in the vagina previous to confinement, and in part obtain entrance through the vulva. In the vagina the condi- tions for their development are peculiarly favorable. The number can be greatly limited by hygienic measures. When they obtain access to the uterine cavity their power for evil is grciitly .-uigmontod. Toward 246 THE rUKUPHKAL STATE. the end of the first week, and, espeeiall}' after leaving the bed, fresh blood often makes its appearance.* The quantity of the lochia varies with the peculiai'ities of the indi- vidual. It is, as a rule, greater in nuiltipar;v, in women who do not uurse their children, and in those of flabby fiber, who habitually men- struate abundantly. The mean quantity, according to Gassner, of the lochia omenta or rubra (to fourth day) amounts to nearly two and a fourth pounds ; of the lochia serosa (to sixth day) to rather more than nine ounces; and of the lochia alba (to ninth day) to six and two thirds ounces; so that the entire amount lost during the first eight days reached the total amount of nearly three and a quarter pounds. The Secretion of Milk. Anatomical Considerations. — The breasts, which furnish the secre- tion of the milk, are two large glands of the compound racemose vari- ety. They are covered by a fine, su]i]ile skin and a layer of adipose I Fig. 129.— Mammary gland, a. nipple, the central iwrtiou of which is retracted : b, areola : c, c, c, c, c lobules of the gland ; 1, sinus, or dilated portion of one of the lactiferous ducts ; A extremities of the lactiferous ducts.

THE PHYSIOLOGY AND MANAGEMENT OF CHILDBED. -f^- twenty-four lobes, which in turn are subdivided into lobules made u]) of a greater or less number of acini, or culs-de-sac. Fine canaliculi start from the latter, and unite together to form the canals of the lobules. These again anastomose, to form a principal canal for eacli lobe, termed the lactiferous ducL The lactiferous ducts terminate at the nipple by small openings measuring only from one sixtieth to one fortieth of an inch. Each duct, as it passes downward, enlarges in the nipple to one twenty-fifth or one twelfth of an inch in diameter, aud beneath the areola it presents an elongated dilatation, from one sixth to one third of an inch in diameter, called the sinus of the duct (Flint). The spaces between the lobes are filled with adipose tissue, and the various elements which constitute the mammary glands are united into a single mass by a dense connective tissue continuous with that of the subcutaneous layer. The acini, which are merely rudiment- ary in the non-pregnant state, are lined with a single layer of small polyhedral cells, assuming a more cylindrical character in the neighbor- hood of the canalicular ducts. The main ducts are lined with low cylindrical cells, and contain m their walls non-striated muscular fibers, the contractions of which are the cause of the spurting of the milk in lactation. During pregnancy the breasts enlarge m consequence of the swell- ing and increase of the connective tissue, the accumulation of fat between the lobes, and the multiplication of the acini, which fill with fatty globules resulting from the disintegration of the lining epithelial cells. The changes in the secretory apparatus give rise to irregularly distributed nodular cords, which, however, at first are most distinct at the periphery, and thence advance toward the center of the organ. With continued development a lactescent fluid is produced, which either exudes spontaneously from the nipple or is discharged by pressure. Milk-Fever. — About the third or fourth day of the childbed period the turgescence of the breasts is suddenly increased, and they become full, tense, nodular, and sensitive to the touch. The axillary glands enlarge, and radiating pains are experienced in the arm and shoulder. The intensity of the mammary congestion varies in differejit individ- uals. It is more pronounced in women who postpone nursing their children until after the secretion of milk is fully established. In ex- ceptional cases it may be absent altogether. Since the general intro- duction of the thermometer into practice, and the better understanding of the causes of febrile temperatures in the puerperal state, the exist- ence of a distinct milk-fever referable to functional disturbances in the breasts during the period in question has been found to be an en- tirely exceptional occurrence. The temperature tables which have been kept with great regularity for the past ten years in the Maternity Hospital of this city prove that, under normal conditipns, the tempera- 248 THE PUERPERAL STATE. tares of tlio third day do not rise above 100^°. With tliis sub-febrile increase there is, indeed, often conjoined considerable general dis- turbance, indicated by slight chilly sensations, headache, anorexia, and a quickened pulse, which, however, disappear in the course of twenty-four hours, with profuse perspiration, and an abundant secre- tion of milk. Most writers regard the higher temperatures which are sometimes found associated with extreme turgescence, tenderness, and Fifi. 180.- Section tliroujili iiL-iiiiis from breast of a nursing woman. iBiUroth.) reddening of the mammae, and which subside when the latter are partially unloaded, as dependent upon a non-suppurative form of parenchymatous inflammation. Composition of Milk. — Milk is composed of a fluid portion and of formed constituents, the first derived from the blood, and the second, termed the milk-globules, from the epithelial contents of the acini. In the production of the milk-globules the gland-cells actively mul- tiply^ and become filled with granular particles, which gradually co- alesce to form drops of fat. Subsequently the nuclei and the contours of the cells disappear, so that the latter consist of mulberry-shaped aggregations of fat-drops held together by the remains of the cell-pro- toplasm. The epithelial elements thus metamorphosed are termed colostrum-corpuscles. They are found sparingly distributed in the crude, imperfectly formed secretion known as colostrum, which is fur- nished by the breasts of women who have been but recently confined. Finally, the fat-globules of large and small size separate from one another, and form an emulsion with the fluid transuded from the blood, a process aided, according to Kehrer, by the diffusion through the fluid of the residual protoplasm of the cells.* * Kehrer. Zur Morphologie des Milch-Caseins, Arch. f. Gynaek., Bd. ii, p. 1. THE PHYSIOLOGY AND MANAGEMENT OP CHILDBED. v^i) Colostrum is a watery, semi-opaque, mueiliagiuous fluid, containing' yellowish streaks composed of fat-globules and fatty-degenerated cells which hang together in stringy masses. It is distinguished from true milk not only in the physical characteristics mentioned, but in the greater proportion of sugar and inorganic salts it contains, and in the . fact that it coagulates upon boiling. It possesses laxative qualities, wliich render it of use to the infant in aiding the removal of the me- conium. Perfectly formed milk contains from 2-5 per cent to 7-6 per cent butter in emulsion, and from 3-2 per cent to six per cent milk-sugar in solution. Both of these substances are directly manufactured by the gland-structures. It possesses likewise a protein substance termed casein, which fluctuates in quantity between one, three, and four per cent. Kehrer maintains that it is not held in the milk in solution, but is composed of particles derived from cell-protoplasm which are diffused through the fluid. The salts in the milk amount to 0*14 per cent.* The Diagnosis of the Puerperal State. — The diagnosis of recent de- livery is based upon the physiological conditions which, we have seen, characterize the puerperal state. Thus, the abdomen is flabby and wrinkled, with pigmented linea alba, and is traversed by white and red lines ; the breasts are full, tense, and nodular, and secrete milk or colostrum ; the areola about the nipple is discolored ; the uterus is enlarged, anteflexed, palpable through the abdominal wall, and is ex- cited to contract by pressure ; the vulva is swollen, the labia gape apart, the hymen is ragged, the perineum is distensible, and in recent cases lacerations, in older ones ulcers or granulating wounds, are found about the vaginal orifice ; in the smooth, lax vagina there is observable the absence of the columns rugarum ; the cervix is soft, wide below and narrowing above, with the labia often torn and contused ; when the finger can be passed into the uterine cavity, thrombi may be felt at the placental site; finally, the lochia are hardly likely to be confounded with haemorrhages or discharges from non-puerperal causes. During the first two weeks an approximative estimate may be made as to the date of confinement by bearing in mind that just after de- livery colostrum is found in the breasts, the lochia are bloody, and the lacerations about the vulva present a fresh appearance ; that during the following days the lochial secretion changes first to a serous and then to a purulent character ; that the uterus gradually diminishes in size, the fundus at the tenth day sinking below the upper border of the symphysis, while the os internum remains patulous to the tenth day, and is usually impassable for the finger after the twelfth day. * Spiegelberg, loc. cit., p. 221. 250 THE PUERPERAL STATE. The Xew-borx Ixfant. With the first inspiration the thorax exjiands and air fills the alveoli of the lungs ; at the same time the blood passes from the right side of the heart to the capillaries of the pulmonary organs, and is returned arterialized to the left side of the heart. As a consequence of the establishment of the pulmonary circulation, the ductus arteri- osus contracts, the foramen ovale closes, and the left ventricle under- goes eccentric hypertrophy. With the diversion of a part of the blood- currents to the lungs, the pressure in the aorta sinks, and the circula- tion in that portion of the umbilical arteries which lies outside the navel ceases, while thoracic aspiration empties the umbilical vein. The cord dries from the cut surface toward the navel, and drops off on the fourth or fifth day. The line of demarkation forms at the termina- tion of a capillary network which extends upward upon the cord to a distance of from three to four lines from the skin. When the cord drops off, a wounded surface is left, which heals in a few days. The swelling upon the presenting part subsides mostly in twenty- four to forty-eight hours. The head slowly resumes its normal shape — a process completed, probably, in the course of two to thi-ee weeks. Soon after birth the meconium is discharged from the intestines, and in a few days the evacuations assume a feculent character. The production of pepsin in the stomach, and the secretion by the pancreas of a fluid capable of emulsifying fats and digesting albuminoid sub- stances, render the assimilation of milk practicable. The kidneys excrete an abundance of urine of a low specific gravity. About the third day an exfoliation of the epithelium begins, which is maintained for a week, or even a longer period. During this time the hyperaemia of the skin is very marked, and imparts to it a red color, which as it fades passes into a yellowish tint. The breasts in both sexes swell very commonly, become red and sensitive, and yield upon pressure a serous, milky fluid. Icterus of the new-born infant is a pretty common affection. Its occurrence is, however, largely influenced by local conditions. Thus, Porak placed the frequency at eighty per cent among the children born in the Hopital Cochin in Paris ; Kehrer, in the vast maternities of Vienna, at sixty-eight per cent ; Ebstein, in Prague, at forty-two per cent ; while West declares it is a rare phenomenon at the Rotunda Hospital in Dublin. It develops usually upon the second or third day, and ends, as a rule, by the sixth to eighth day. Kehrer * has shown statistically that it occurs more frequently in boys, in prema- ture mfants, in the children of primiparae, and as a consequence of malpresentations. It is likewise promoted by atelectasis, by intestinal * Kehrer, Studien iiber den Icterus Neonatorum, Jahrbuch f. Paediatrik, Bd. ii, p. 71, 1871. THE PHYSlULOGV AND MANAGEJMKNT OF CHILDBED. 251 affections, bv depressing the temperature of the child, by insufficient feeding, and, in a word, by all the various patliological conditions and unfavorable hygienic influences intensifying or giving an abnormal direction to the ordinary changes which take place in the blood (Eb- stein). Its frequency in lying-in hospitals is probablv connected with a septic infection, for which the wounded surface at the navel furnishes the point of entry. It is rarely dependent upon gastro-duodenal ca- tarrh, npon a narrowing of the bile-duct, or upon retention of meconi- um. The ffeces are stained with bile. In all the tissues of the body, and most abundantly in the kidneys, pigment-crystals and yellowish- red amorphous granules are fonnd deposited in greater or less quanti- ties. It is as yet an unsettled question as to Avhether these pigment- bodies are the products of the liver or result from the disintegration of the blood-corpuscles. A very considerable destruction of the latter is found in all cases of icterus of the new-born. The tissue-waste is like- wise marked. Hofmeier * found the average loss of weight in icteric children on the third day after birth was 9-3 per cent of the original weight, whereas in non-icteric children it was but 5-69 per cent. The urine contained an excess of nrea and uric acid, and pigment-bodies proportioned to the intensity of the icterus. The pigment-bodies, he claims, 'nirnished the characteristic color reaction with nitric acid of the acids of the bile. An expectant treatment is the only rational one. Laxatives are unnecessary, and perhaps harmful. f Owing to the discharge of meconium and urine, and the limited amount of sustenance at its disposal, the new-born infant experiences a loss of weight in the first two or three days, estimated at from seven to eight ounces. After the second or third day the loss is gradually i-eeovered, so that between the fifth and eighth days the weight at birth is reached. The loss of weight is greater in the children of primipara? than in those of multipara?, in artificially nourished infants, and where the immediate application of the ligature to the cord at birth has been resorted to. The Maxagemext of the Puerperal State. Sleep.— After every precaution has been taken against haemorrhage, after the i):itient has been washed carefully and i)laced upon clean, dry l)edding, and after the baby has been bathed and dressed, it is very de- sirable that the mother should enjoy a few hours of refreshing sleep. To this end the room should be darkened and absolute stillness en- forced. The crying of the baby, the affectionate salutation of friends, or the tidying of the room by household Marthas, often becomes the * Hofmeier, Die Gelbsucht der neugeborencn, Ztschr. fiir Geburtsli. iiml Gyiiaek., vol. vii, p. 287. t Ebstein, Ueber die Gelbsucht bei neugeboiviu'ii Kiiuloni. Volkiiiiiiurs Sanunl. klin. Vortr., No. 180. 252 THE PUERPERAL STATE. starting-point of nervous restlessness, which is with difficulty over- come by the aid of the strongest soporifics. Should the mother feel faint and exhausted, she should be allowed a cup of hot tea or bouillon. In multipara it is well to leave with the nurse some form of ano- dyne, to be administered in case sleep is interrupted by the frequent recurrence and severity of the after-pains. Opiates, while they lull the pain, do not, after labor, arrest those physiological changes in the uterus with which the after-pains are associated. Passing Urine. — As the natural impulse to urinate after delivery is very feeble, even when the bladder is full, the nurse should be instructed to solicit the patient to pass water in the course of eight or ten hours. It is usually recommended that the act of urination should be performed upon the back, which, of course, necessitates the use of the bed-pan. It has been my own rule to enforce the dorsal position during the first days of childbed, but there are a good many women who are able to pass water without difficulty in the sitting posture, who fail in the attempt. when recumbent. Goodell therefore advocates the practice of raising the woman for purposes of urination from the beginning of childbed. He believes that the occasional assumption of the ujjright attitude for a brief period possesses the advantage of promoting drain- age of the parturient canal, and of forestalling the evils incident to lochial stagnation in the vagina. The belief tliat such a course in- creases the risk of haemorrhage he regards as unfounded. The physician should make it a rule to visit his patient within twelve hours from the time of confinement. He should then inquire not only whether she lias passed water, but ascertain the quantity voided. If the quantity has not exceeded three to four ounces, he should introduce the catheter and make sure that the bladder is completely emptied. In cases of re- tention, the urine should be drawn at least four times in the twenty- four hours. Before using the catheter, the lochia should be carefully washed from the external parts with a warm carbolized fluid (two per cent), as the lochial discharge after the first day is liable to excite cystitis. Both the catheter and the operator's hand should be surgi- cally clean. In passing the catheter beneath the bedclothes, the ure- thral orifice can readily be detected by first feeling for the tumefied urethra with the index-finger of the right hand through the anterior vaginal wall, and then following it in a forward direction until the meatus is reached. Visits of the Physician. — The physician should see his patient at least once daily during the first week following confinement. During the first four days it is my custom to make both a morning and evening visit, not only for the purpose of noting carefully the pulse and tem- perature, but to be sure that my patient is not made a victim to ti-adi- tional prejudices and siiperstitions. If tlie physician will take the THE PHYSIOLOGY AND MANAGEMENT OF CHILDBED. 253 trouble to call occasionally upon his patient subsequent to the first week, to insure the unretarded progress of puerperal convalescence, he will do much to circumscribe the field of gynaecological practice. General Directions. — Great care should be taken to keep the air of the lying-in chamber fresh and pure. If the room is warm, the patient sliould be lightly covered, owing to the tendency during childbed to profuse perspirations. There is no foundation for the prevalent belief that it is dangerous to comb the hair of a puerperal woman. Nothing contributes so much to the removal of soreness, and the healing of wounds in the genital canal, as cleanliness. Where the antiseptic pad is employed this object is attained by thoroughly washing the external parts with a bichloride (1 : 5,000) or a carbolic solution (two per cent), whenever it becomes necessary to change the pad either by reason of the evacuation of the bowels or bladder, or because of the saturation of the pad with the lochial dis- charge. From the latter cause alone a change once in four hours in the early childbed period is to be advocated. The pad removed should be destroyed. When the ordinary napkin is used external ablutions should be em- ployed several times daily. It is a question whether the present tend- ency to prohibit the vaginal douche is warranted. Against its employ- ment it may be urged, that in spite of the addition of carbolic acid or corrosive sublimate there is statistical evidence that the vaginal douche augments the chances of infection. In hospital practice it has invariably increased the morbidity and mortality rate. In my own private prac- tice, on the other hand, it has proved to many patients a source of comfort. When carefully administered by nurses trained to aseptic work it has given rise to no injurious symptoms, and I still occa- sionally employ it — not, however, as a prophylactic, but because of the property possessed by hot vaginal injections to assuage pelvic dis- comfort. ^^.^ Diet— The diet should be selected with reference to the physio- logical requirements of the patient. Thus, during the first three days, when, as a rule, the patient is thirsty and is indifferent to solid food, the diet should consist of gruel, milk, milk-toast, and tea ; to which may be added clear soups and bouillon, and soft-boiled eggs, should more stimulating aliments be called for. It is equally desirable, on the one hand, to avoid exciting colics and catarrhal affections of the stomach by too early resorting to a substantial regimen, and, on the other, to remember that the speedy establishment of an abundant milk secretion is apt to be hindered by subjecting women to a process of semi-starva- tion. After the bowels have moved on the third or fourth day, the normal appetite usually returns. All easily digested articles of food, such as eggs, chicken-broth, small birds, steak, chops, and the like, according to the taste of the patient, should then be allowed. Cooked 254 THE PUERPERAL STATE. fruits are of service in overcoming the natural constipation of the puerperal period. The popular prejudice against fish and vegetables containing a large amount of nitrogenized substances seems to me well founded. Laxatives. — The canonical practice of administering a laxative on the third day is of unquestionable utility. In most women there occurs an accumulation of fecal matter during the last weeks of preg- nancy — an accumulation which is often enormous in quantity, and which creates a predisposition to puerperal affections. The remedies selected should, however, be adapted to the peculiarities of the individual. In some women an ordinary injection of soap and olive-oil in water suffices to procure an adequate evacuation ; in others, the object is ful- filled by the milder laxatives, such as the compound rhubarb pill, a claret-glass of Huuyadi-Janos water, or the compound licorice jjowder of the German pharmacopoeia ; while in obstinate cases a calomel purge, or some such combination as the post-jjaritim pill of the late Prof. Barker,* will be found requisite. Castor oil I give only in cases of severe colic, either alone or combined with fifteen drops of laudanum. In hemorrhoids complicating puerj^eral convalescence, I can add my testimony to that already given by Prof. Barker as to the specific curative effect of half-grain doses of aloes administered night and morning. Nursing. — Every healthy woman should nurse her child at least through the puerperal period.f The advisability of continuing lacta- tion subsequent to the resumption of household duties must depend upon the question as to whether the mother is in a position to make the necessary sacrifices to the interests of the child. When the do- mestic and social demands upon her time and thoughts are numerous and pressing, lactation is apt to be imperfect, and the child will not thrive. Humanity, in such cases, requires that the child be surren- dered to a wet-nurse. Nursing may be rendered impossible by a lack of milk, by flattened, misshapen nipples, and by the health of the mother. It should be prohibited in phthisis, in epilepsy, and in cases of syphilis contracted shortly before the birth of the child. The child should be applied to the breast after the mother has rested, and within the first twelve hours following the end of labor. Soon after birth the child seizes the nipple eagerly, and though the quantity of nourishment obtained is small, it is infinitely better adapted to the child's needs than the catnip-teas and sweet oil which monthly * Ext. colocynth. comp., 3j ; ext. hyoscyami, gr. xv. ; pulv. aloes soc, gr. x.; ext. nuc. vom., gr. v. : podophyllin, ipecacuanha, aa, gr. j.

Of these, two usually act efficiently and without causing pain. t The quantity of milk daily consumed by the infant during the first nine days increases, according to Deneke, gradually from one ounce and a half on the first day to about fourteen ounces on the ninth day.

The early apjolication of the child to the breast benefits the mother by promoting the contractions and the involution of the uterus, and by lessening the painful distention of the breasts which occurs at the time when the function of lactation is fully established. As the child sleeps for the most part during the first few days of existence, no rule can be laid down with regard to the frequency with which it should be placed to the breast. Afterward it should be ac- customed to some regular routine. So long as the stomach is of small capacity and regurgitates a portion of its food, the interval should not exceed a couple of hours. From an early period, however, the child should be accustomed to sleep six hours at night, which gives an op- portunity for the mother to recuperate her strength. This discipline is of course not practicable where the child sleeps in the same bed with the mother. After six months the child should not nurse oftener than five or six times in the twenty-four hours. The breasts should be suckled in alternation. The nipples should be carefully washed both before and after nursing. The addition of boric acid to the water prevents the development of fungi. The ex- treme sensitiveness of the nipples at the commencement of lactation can be greatly relieved by applying constantly to them a rag wet with the liquor plumM subacetat.j in the proportion of a teaspoonful to a tumbler of water. For a few days a metallic shield over the nipples, to prevent the rubbing of the night-dress or the bedclothes, is a source of comfort. Duration of Lying-in Period. — Most women expect permission to be given them to sit vip ujjon the tenth day. There should, however, be no fixed rule about leaving the bed which does not take into account the individuality of the specific case. Not to leave the bed before the tenth day is a safe rule in normal puerperal convalescence ; but, where there are wounds to heal by granulation, a much longer period of time may be necessary. Garrigues * expressed his conviction that " the up- right and sitting postures ought to be carefully avoided until involu- tion has proceeded so far that the uterus has receded from the anterior wall of the abdomen and returned to the pelvic cavity " — a rule which would allow one woman to sit up in a week, while another would be kept in bed two weeks, or even longer. The continuance of the lochia rubra should serve as a warning against a change to the upright posi- tion. The first attempt at getting up should be tentative. The re- sumption of household duties should be postponed until the patient can walk about without fatigue or backache. When the abdominal walls are greatly relaxed, a well-fitted bandage should be worn for weeks subsequent to delivery. * Garrigues, Rest after Delivery, Am. Jour, of Obstet., October, 1880, p. 861. 256 THE PUERPERAL STATE. The Cake of the JS^ew-bokn Infant. As the new-born infant possesses feeble powers of resistance to cold, the first bath should be ninety-eight degrees, or nearly that of the body. The vernix caseosa should be softened by oil or fat-inunc- tion, and gentleness employed in its removal. The child should then be gently dried in soft, warm cloths, and carefully examined with reference to any possible defect of formation or development. The cord should be wrapped in absorbent cotton,* and held in place upon the left side by a flannel bandage. After the cord has separated, the wounded surface should be dressed with iodoform, or bismuth powder. f The clothing of the child is the province of the nurse, and varies con- siderably in the different social ranks. Cleanliness and fresh air are essential to healthy development. To avoid sprue, the mouth of the child should be washed with cool water each time after nursing. Selecting a Wet-Nurse.— Should the mother be unable to nurse her child, a wet-nurse should be urgently recommended. In selecting the latter, an examination should be made with regard to her constitution and health. The physician should, by inspecting the throat, the legs, the glands of the neck, and, if possible, the genital organs, exclude the existence of a syphilitic or strumous taint. A nurse should be between twenty and thirty-five years of age, and should present all the appearances of good health. The gums should be red and firm ; the breasts should preferably possess a pyriform shape, and should be mar- bled with blue veins ; it is not necessary that they should be large, but they should be firm, elastic, and nodular from abundance of glandular structure ; the nipples should be well formed, prominent, and free from cracks and erosions ; the milk should flow easily, and not be too bluish in color ; the age of the milk should bear some correspoTidence to that of the child to be suckled. Aside from the question of adapta- bility, it is obvious that, where a great discrepancy exists, the milk of the nurse is liable to fail before the time of weaning is reached. One of the best tests of a nurse's capacity is the appearance of her own child. If the latter is plump, with well-rounded limbs, and with a healthy skin and mucous membranes, the presumptions are in her * This plan, which I first saw recommended by Dr. W. D. Babcock, of Evans- ville, Indiana (Am. Jour, of Obstet., October, 1888, p. 1055), has since been warmly- praised by Crede and Weber, Arch. f. Gynaek., vol. xxxiii, p. 73. f Dr. Goodell seizes the cord, after it has been cut as usual, between the thumb and forefinger of the left hand, near the navel, and then strips off the gelatin of Wharton with the thumb and forefinger of the right hand. The pressure at the navel is next temporarily suspended where the internal portions of the vessels collapse. The cord is thereupon subjected to a second stripping, tied in the usual manner, and left free without any dressing whatever. The result is that it separates without any bad smell.

THE PHYSIOLOGY AND MANAGEMENT OF CHILDBED. 257 favor, even if she does not present in her own person, as Jacobi sport- ively suggests, a "combination of Aphrodite, Athene, and Psyche." When a choice has once been made, a change should not be recom- mended without a fair trial. It is by no means uncommon for a nurse but recently separated from her child, placed among strangers, and introduced to a foreign mode of life, to temporarily puffer from a dimi- nution of the lacteal secretion, the milk returning in a brief period under the influence of kindness, habit, and a nourishing regimen. Moderate exercise is necessary for the maintenance of health. The nurse should be allow^ed to drink milk freely, but malt liquors should be prohibited, at least until toward the close of lactation. Artificial Feeding. — If it is impossible to procure the services of a wet-nurse, or if the aversion of the parents to wet-nurses as a class proves unconquerable, artificial alimentation must be tried. It is un- questionable that many babies thrive fairly when brought up on the bottle. For success, scrupulous cleanliness, punctuality, intelligence, and experience are requisite. The beautiful roundness of outline, the Men aise, and the easy dentition of infants at the breast are, however, rarely attainable by those who are brought up by hand. Bottle-fed infants are apt to be lean, to be subject to attacks of indigestion, and to suffer from nervous disturbances when teething. If cow's milk is used as a substitute for human milk, the experiment is more likely to prove a success in the country, where the milk can be obtained fresh morning and evening, than in the city, where milk is of necessity at least twelve hours old at the time of delivery, and thirty-six hours old before a fresh supply can be obtained. My own experience inclines me to favor employing, where it is practicable, milk from one cow, especially if the cow is selected with reference to the child's individu- ality, precisely in the same manner as a wet-nurse would be selected. The fitness of the milk to the child is to be determined rather by ex- periment than by analysis. In a general way, however, it is well to remember that the milk of a very young cow is deficient in fat-glob- ules, while that of an old cow is apt to err on the side of excessive richness, and that either extreme is equally liable to tax the infantile organs of digestion. The difference in the digestibility of human and cow's milk is de- pendent upon a difference in the molecular arrangement of the casein varieties they respectively contain. The acid of the stomach precipi- tates human casein in the form of flocculent shreds, while that of the cow's milk is converted into firm, solid masses. Now, of the two forms it has been experimentally proved that the former is much more solu- ble in the gastric juice than the latter. With many physicians the favorite plan for neutralizing this objection consists in substituting cream for milk (diluted at first with three and afterward with two parts water [Biedert]), and thus to reduce the quantity of casein to 17 258 THE PUERPERAL STATE. minimum proportions; but this diet, by confining the child almost entirely to the hydrocarbons, to the exclusion of the protein constit- uents, has never seemed to me in practice, even when well borne, to meet the full tissue requirements of a growing child. After many trials of this mixture, which found a warm advocate in the late Pro- fessor Childs, of this city, I have finally returned to milk of good standard quality, stirring it before using to distribute the fat-globules evenly between the different layers, and adding to it water propor- tioned to the age of the child, beginning with eight tablespoonfuls of milk to eight of water, increasing the one and diminishing the other a tablespoonful at a time as rapidly as the digestive organs exhibit a toleration of the change. The water does not, of course, alter the chemical constitution of the casein, but aids digestion by provoking an increased flow of the gastric juice, and incidentally contributes to alleviate thirst (Jacobi). City milk should be boiled to prevent fermentation,* an unnecessary practice when milk can be obtained fresh night and morning. Instead of plain water, Jacobi has pointed out the utility of using some sub- stance " which by its physical consistence is able to hold the casein- clots in suspension, thus protecting the stomach from irritation while they are being prepared for dissolution." I have been in the habit of following out to this end his earlier suggestion, to employ an indiffer- ent substance, as gum-arabic or isinglass, for very young children, and afterward a thin decoction of oatmeal or barley, according to the tend- ency of the child to constipation or diarrhoea. The distress occasioned in some cases by the casein is often relieved by subjecting the milk to a peptonizing process. Condensed milk is popular with many physicians, because children with whom it agrees fatten upon it, and suffer but little from indiges- tion and loose passages. The large amount of sugar it contains un- fits it, however, for prolonged use. I have seen a number of children exclusively fed upon it, after passing through apparently a blooming infancy, develop symptoms of rickets at the end of their first year. I have, however, been in the habit of allowing its habitual use during the first three months of existence, and in the city during the hot months of summer. Whatever the preparation selected, it should be warmed to blood- heat before it is given to the child. A small quantity of salt and a grain or two of bicarbonate of soda, or a tablespoonful of lime-water, * This object is best attained by means of the steam sterilizer. The bottles in this apparatus, after being filled with milk, are immersed in boiling water until freed from micro-organisms. They are then hermetically sealed. The milk when thus treated will remain sweet for days. If the sterilization be complete, the milk will keep indefinitely. The perfection of the method immensely reduces the risks of bottle-feeding. THE PHYSIOLOGY AND MANAGEMENT OF CHILDBED. 259 should be added to the infant's food, the former to promote assimila- tion, and the latter to neutralize any free acid the milk may chance to contain. When artificially reared, many children do not gain flesh in spite of apparently healthy digestion. I have often derived great benefit, after the third month, from the addition to each bottle of a tablespoonful of Lofflund's Liebig's food for infants. Presumably the various forms of malt extracts now so popular in this country would serve the purpose equally well. The bottle from which the child is fed should be scalded each time that it is used, and should then be filled with cold water to which a little soda has been added. The tube and mouth-piece should both be washed, cleaned with a brush, and allowed to soak in cold water in the intervals of feeding. Unless every precaution is taken to prevent the development of fungi, a bottle-fed infant will never prosper. THE PATHOLOGY OF PREG:n:A]N^CT. CHAPTER XIV. ACCIDENTAL COMPLICATIONS.— ABNORMITIES OF THE UTERUS. Variola. — Rubeola. — Scarlatina.— Scarlatina puerperalis.— Cholera.— Typhus, ty- phoid, and relapsing fever.— Malarial fever.— Icterus.— Cardiac diseases.— Pneu- monia.— Emphysema, chronic pleurisy, and empyema.— Phthisis. — Syphilis. — Chorea. — Surgical operations during pregnancy. — Double uterus. — Ante version and anteflexion.— Retroversion. — Retroflexion. — Prolapse of uterus and vagina. — Hernias. The pathology of pregnancy includes the various morbid condi- tions which exercise an unfavorable influence upon pregnancy, whether of maternal or fetal origin. The maternal diseases comprehended under this title may consist of simple exaggerations of normal disturbances — a class which has, however, already received attention in connection with the chapter on the management of pregnancy ; accidental complications which materially influence the circulation or the integrity of the pelvic organs; and, finally, diseases of the uterus and the uterine append- ages which endanger the health of the ovum, or pave the way to its expulsion. The pathological processes which affect the ovum may be primary, or may result secondarily from maternal disturbances. The haemorrhages of the first half of pregnancy and the prema- ture expulsion of the ovum are ordinarily the result of fetal or mater- nal disease. Their consideration, therefore, forms a fitting conclusion to the subject-matter in hand. The management of the haemorrhages occurring in the second half of pregnancy requires a preliminary knowledge of the operative pro- cedures of midwifery. Its consideration will therefore be postponed until the principles governing the conduct of difficult labor have un- dergone discussion. Morbid states which exercise an unfavorable influence less during pregnancy than after the development of labor will, to avoid double mention, be considered in connection with the pathology of the latter process. ACCIDENTAL COMPLICATIONS. 261 Accidental Complicatioxs of Pkegnaxcy. Variola attacks pregnant women more frequently than any other eruptive fever, and, although it manifests a preference for those in whom pregnancy is not far advanced, its type is severer and its prog- nosis graver when it affects women near their confinement. Variola is, unless of a mild form, a peculiarly dangerous complica- tion of pregnancy, greatly imperiling the life of both mother and foetus,* through its tendency to metrorrhagia and abortion. When the disease pursues its course without producing abortion, the child may present characteristic variolous cicatrices, or the latter may be absent. Occasionally the child remains unaffected by the dis- ease until after birth, and may sometimes escape it altogether. During epidemics of variola, women may, without manifesting other symptoms of infection from the variolous poison, give birth to prema- ture children, who remain unaffected with the disease. Children sometimes suffer from variola either before or soon after birth, while their mothers enjoy complete immunity from the disease.f The healthy child of a mother affected with variola, or of one vac- cinated during pregnancy, may be insusceptible to vaccinia for some time after birth. J It is advisable that all women becoming pregnant during an epi- demic of variola should be immediately vaccinated. Measles is an infrequent complication of pregnancy. In eleven cases collected by Klotz, nine were attended by premature delivery. This, according to Klotz,* is attributable not to excessive heat, nor to haemorrhagic tendencies, but to an exanthematous form of endometritis. Of the four cases occurring in his personal practice, all recovered. Of sixteen cases collected by Underhill,|| in seven attacked during pregnancy there were two deaths ; in seven cases in which the attack occurred at the end of pregnancy, two died ; while in two cases at- tacked in childbed, both died. Aside from a disposition to puerperal haemorrhage, pneumonia is a frequent and dangerous complication. In measles, premature delivery is apt to be followed by chronic en- dometritis, which, in case of renewed pregnancy, becomes again a cause of abortion. The poison is sometimes transferred from the mother to the child during intrauterine existence. * Meyer, Ueber Poeken, beim weiblichen Geschlecht, Berlin, Beitr. z.

Scarlatina is a less frequent complication of pregnancy than vari- ola, attacks priniipara? by preference, although not exclusively, and manifests a decided tendency to develop itself in the puerperal state, even when infection has taken place in the earlier months of preg- nancy. Olshausen * was able to collect from all the medical literature at his disposal only seven cases of scarlatina occurring during preg- nancy, while the number of cases taking place in the puerperal state amounted to one hundred and thirty-four. The theory that, in cases of exposure during pregnancy, the poison may remain dormant in the system, and after weeks or months of in- cubation may break out in childbed, is not inherently probable, f The mortality of scarlatina occurring in pregnancy and in the puerperal state varies notably in different epidemics.;}; Attacks oc- curring immediately after confinement are more fatal than those de- veloped later. The stage of invasion may be entirely absent, or may exist for one or two days before the appearance of the eruption. When present, it is characterized by intense febrile movement, emesis, and notable con- gestion of the face. Usually, however, the earliest announcement of the attack consists in the sudden development of the eruption on all parts of the body. In severe cases the eruption soon assumes a charac- teristic livid color, which is usually retained until the fatal issue, should the latter occur within a week The pharyngitis and tonsillitis and the tongue changes are either very mild or entirely absent. Diarrhoea is a frequent and dangerous complication. Albuminuria is common. Aside from the above-men tioned peculiarities, puerperal scarlatina presents no important vari- ations from the clinical history of ordinary scarlet fever. The lochial discharge, the lacteal secretion, and tlie uterine involution are un- affected by the disease Some authors have applied the designation " scarlatina puerperalis " to an infectious disease which, although resembling scarlatina, is still said to be identical with or closely related to puerperal fever. The theory advocated by them is based upon the fact that, in the cases upon which their deductions are founded, the angina was trivial in character ; the attacks occurred usually within three days after con- finement ; infection with scarlatinus jjoison could not, in the majority of cases, be established ; the rate of mortality was very high, and peri- * Olshausen, Untersueh. iiber d.

Meyer, eighteen cases with one death. ACCIDENTAL COMPLICATIONS. 263 tonitis and cellulitis were often revealed on autopsy. Olshausen* concludes with apparent justice, after a careful review of the reasons for and against the introduction of this new disease into obstetric nosol- ogy, that the grounds for its establishment are insufficient, and that the cases of so-called " scarlatina puerperalis " are nothing more than ordinary cases of scarlet fever modified by the concomitant puerperal condition, but in no way akin to puerperal pyaemia or septica?mia. It is worthy of note, that scarlatina and puerperal fever may occur in combina'tion without mutually affecting their respective signs and symptoms. Braxton Hicks f advocates the extreme theory that a puerperal woman when infected with scarlatina develops puerperal fever, and that persons other than lying-in women contracting the dis- ease through intercourse with the puerperal patients are attacked by scarlatina of the usual form. Antipyretic measures, particularly cool baths, are indicated in pro- portion to the intensity of the febrile movement. Cathartics are to be avoided, because of the inherent tendency to diarrhoea, alluded to above. Special attention should be paid to the treatment of septic symptoms where these coexist. Cholera. — The predisposition on the part of ])regnant and puer- peral women to cholera Asiatica is not usually decided, but varies with different epidemics, and is more marked in cities than in the country. Women are most liable to an attack of cholera in the latter half of pregnancy, particularly in the seventh and eighth months, and the prognosis is gravest for cases occurring at those periods. The prognosis is almost necessarily fatal in the case of children born before the ninth month.;); The intensity of the disease is somewhat mitigated by the existence of the puerperal state. Slight attacks of cholera may take their natural course without prejudicial effects upon mother or foetus, but the disease frequently results in abortion or premature de- livery, due in part to hasmorrhagic metritis. The pathological uterine conditions observed in the cases recorded by Slavjansky ^ comprised roughening of the inner surface of the uterus by dark-violet shreds of the decidua vera, numerous extravasations permeating the mucous membrane, which remained intact in some places and was ulcerated at others, besides the presence in the uterine cavity of coagulated blood, pus, and shreds of the uterine mucous membrane. The placenta fetalis presented granular degeneration and almost complete disintegration of the epithelium covering the villi. Both of * R. Olshausen, Ioc. cit. f BraxtOxV Hicks, Trans, of the Obstet.

Schroeder * refers the death of the foetus to asphyxia pro- duced by changes in the maternal blood which interfere with the pla- cental respiratory function. The clinical history of cholera is not materially affected by coexisting pregnancy, except in so far as uterine symptoms are concerned. Eclampsia sometimes occurs, and irregular uterine pains may persist for several days without producing ab'ortion.f Cholera does not specially predispose to puerperal diseases, nor does it afford protection against them. Lactation, whether commencing or already established, is not markedly affected by cholera, although the lochia are often almost suppressed. The treatment is conducted upon general principles. The artifi- cial induction of premature delivery has had many advocates, on ac- count of its supposed tendency to ameliorate the prognosis, but has now fallen into disrepute, although Judicious measures to hasten par- turition, already begun bv nature, are regarded as justifiable. Typhus, Typhoid, and Relapsing Fevers. — These fevers more fre- quently complicate the earlier than the later months of I3regnancy, and affect the prognosis more seriously at the former epoch, owing to the greater tendency then existing to protracted jjost-partiwi haimor- rhage.J They may also, rarely, complicate the puerperal state. Typhus fever manifests a less marked tendency to the induction of abortion or of premature delivery than either typhoid or relapsing fever, probably because it is less frequently accompanied by metrorrha- gia.* It, however, occasionally produces these results, thereby essen- tially increasing the danger of a lethal termination. || Typhoid fever is frequently, and relapsing fever almost constantly, accompanied by abortion or by premature delivery induced by profuse uterine haemorrhages,"^ and thus greatly endanger life. The clinical history and the treatment of the fevers in question are unaffected by coexisting pregnancy except in so far as symptoms and indications having reference to the occurrence of metrorrhagia, abortion, or pre- mature delivery, are concerned. Malarial Fever. — Malarial fever is not a very frequent complication of pregnancy, perhaps because the latter secures a certain freedom from exposure to the malarial poison. Women who have previously experienced malarial fever, and who have been considered cured of the disease for several years, often suffer a relapse during subsequent preg- * Schroeder, Lehrb. d.

ACCIDENTAL COMPLICATIONS. 265 nancies.* Attacks occurring under these circumstances may be re- garded as acute exacerbations of a chronic malarial disease which has remained latent for a certain time. Malarial fever, according to Runge,t Ritter,^ and most observers in this country, does not produce abortion except iu rare instances, even when the febrile phenomena persist up to the termination bf pregnancy ; though Goth * has re- ported forty-six cases, in nineteen of which either abortion or premature delivery took place. Parturition usually suspends the periodic parox- ysms, supposing them to have continued up to confinement, possibly owing to the loss of blood dependent on delivery, but the rule is not without exceptions. During the puerperal state, however, particularly in the second and third weeks, the paroxysms usually return, or a latent malarial cachexia may manifest itself in the manner previously alluded to. I The disease may be communicated to the foetus, as has been proved by the detection of the characteristic pathological appearances induced by malarial poisoning in the spleen, and by the discovery of malarial pigment-granules in the blood and skin of children dying be- fore or immediately after birth.^ Hubbard^ reported an interesting case of intra-uterine malarial fever of the tertian type, in which the fetal movements were entirely suspended during the maternal paroxysms, and returned during the intermissions. The woman was confined during an intermission. On the following day the mother and child had a simultaneous paroxysm. Quinia was now administered, with the result of curing both mother and child — the latter obtaining the antiperiodic through the medium of the mother's milk. The usual course of malarial fever is altered by coexisting preg- nancy. Intermissions are usually wanting, and the fever becomes continued or remittent, the chills occurring irregularly. J Even those cases which most nearly approximate the usual malarial course show a tendency to anticipation or retardation of the paroxysms. The fever may assume a pernicious character, its tendency in this direction being accounted for by the nervous prostration and autemia attendant upon the puerperal condition. Quinia best controls the febrile phenomena, but must be given in large doses, since the powers of digestion and of assimilation are seriously impaired by the puerperal state.|; * Robert Barnes.

Icterus.— Icterus, although a i3henomeuon of rare occurrence dur- ing pregnancy, is interesting and important on account of its tendency to precede or to accompany the fatal pathological changes and symp- tomatic events connected with acute yellow atrophy of the liver. It is ordinarily assumed that this grave general disease is developed from a form of icterus which, when compRcating pregnancy, usually has etiological relations identical with those of simple obstructive or so- called'' hepatic jaundice, although the causative condition frequently eludes observation. The development in pregnancy of icterus termi- nating fatally is also sometimes due to the lesions of phosphorus- poisoning. Davidson* attributes the fatal influence of pregnancy upon the course of simple icterus to the three following causes: 1. The impairment of the renal excretory function, due to the passive congestion produced by uterine pressure upon the renal veins. This etiological factor operates by causing the retention in the blood of the reabsorbed biliary acids, which, according to the investigations of Traube and others, are of themselves capable, even when present in the blood in moderate quantity, of producing acute yellow atrophy. 2. The hydraemia of pregnancy, which renders the system less capable of resistance to toxic agencies. 3. The impairment of cardiac activ- ity, due to the retention of the biliary acids, which still further com- promises renal eliminative action. Icterus often produces abortion by destroying the life of the foetus. The causative connection between icteius and fetal death has been proved by the intense icterus of the dead foetus, by the detection of biliary acids in its blood, and by the exclusion of other causes. After abortion a previously benign icterus may speedily develop all the characteristic lesions and symptoms of acute yellow atrophy. f Under these circumstances the sudden advent of the fatal symptoms may be accounted for by the anajmia and hy- drsemia induced by the ha?morrhage accompanying parturition. As- suming the correctness of the above-mentioned deductions with refer- ence to the usual etiology of fatal icterus complicating pregnancy, we must admit the urgent indication in these cases for measures cal- culated to facilitate the elimination of the biliary acids from the blood by restoring the normal excretory function of the kidneys. An early resort to appropriate measures might, partially or entirely, prevent the accumulation of the poison upon whose presence such baneful results are believed to depend. Cardiac Diseases. — The various effects produced upon pregnancy by coexisting heart-disease depeiid entirely upon the seat and character of the cardiac affection. While the results of myocarditis are serious, April, 1880), furnishes a most valuable addition to our knowledge of the symptome and treatment of this disease. * Davidson, Monatsschr. f. Geburtsk., Bd. xxx, H. vi, 1867, p. 465. t ScHROEDER, Lehrbuch der Geburtsh., p. 366. I ACCIDENTAL COMPLICATIONS. 267 because of its interference with the development of cardiac hyper- trophy adequate for the compensation of existing valvular lesions, and acute endocarditis, occurring during pregnancy, shows a marked tend- ency to assume the fatal ulcerative form,* pericarditis has no percep- tible effect upon the normal course of utero-gestution.f Chronic en- docarditis often produces disastrous results, which may, in general terms, be accounted for by the fact that an amount of cardiac hyper- trophy completely compensatory for pre-existing valvular lesions is no longer able to overcome the increased arterial and venous pressure prevailing during pregnancy, or to adapt itself to the sudden variations in vascular tension due to the parturient act. The augmented arterial pressure which calls for increased cardiac activity is referable, in part, to the newly developed utero-placental circulation. It is also attrib- uted by some authors to the actual pressure of the gravid uterus upon the aorta ; while Spiegelberg J believes it to be measurably due to the plethora of pregnancy, and to the limitation of the intra-thoracic space by the encroachments of the diaphragm. An important source of varying and perturbed heart-action is, moreover, found during labor in the suddenly changing conditions of pressure produced by the alter- nating uterine contractions and relaxations with the corresponding violent respiratory efforts. Spiegelberg* refers the symptoms of aortic insufficiency or stenosis, which are usually most marked in the later months of pregnancy, solely to cardiac disturbances due to increased arterial tension, and the disappearance of these symptoms after birth to the restitution of the normal pressure. McDonald || refers the improvement not so much to the diminution of the arterial tension as to the absence of the extra tension associated with the bearing-down effort. Spiegelberg considers the grave symptoms of mitral disease often presenting themselves soon after confinement as referable to excessive distention of the right heart with blood forced into it from the contracted uterus. Fritsch^ opposes this view,' and attributes the morbid phenomena of mitral disease to the accumulation of blood in the abdominal vessels recently released from the pressure of the gravid uterus, and to the cardiac paralysis resulting from an insufficient blood-supply and con- sequent defective nutrition of the heart. The hydremia of the puerperal state may contribute to the impair- * Lebert, Beitr. zur Casuistik der Herz- und Gefaf5skrankheiten im Puerperium, Arch. f. Gynaek., Bd. iii, 1872, p. 39. •(■ PoRAK.

Fresh inflammatory affections may attack the valves and endocar- dium of a heart already weakened by disease. This occurs by prefer- ence in cardiac cases of more recent origin. In all cases of heart disease, and especially in those with acute symptoms, there is great danger of embolism. Slight exposure to cold and exertion in preg- nant patients with cardiac diseases is liable to occasion pulmonary dis- turbances. These appear usually in the second half of pregnancy.* The symptoms of aortic valvular disease are usually manifested during the latter half of pregnancy. They consist in palpitations, dyspnoea, and, in extreme cases, in abortion or premature delivery. Should pregnancy proceed to a normal termination, the symptoms are aggravated by parturition, and syncope is of common occurrence, but the symptoms disappear speedily after labor is ended. Mitral valvular lesions, if slight or completely compensated for, may not manifest their existence by any rational symptoms. If, however, the compen- sation bo inadequate, the patient's life may be greatly and sometimes suddenly endangered by the occurrence, either before or after confine- ment, of extreme pulmonary congestion and oedema, ascites, albumi- nuria, or metrorrhagia. The foetus may die in utero, as the result of metrorrhagia or of impaired nutrition due to deficient oxygenation of the maternal blood. Children whose mothers are the victims of car- diac disease are often imperfectly developed, and predisposed to un- timely death. The prognosis is based upon the general conditions of the patient. In seventeen of the thirty-one cases collected by McDon- ald the patients died. The prognosis is impaired by coexisting pul- monary lesions, tending to obstruct the circulation in the lungs, as well as by diseases of other vital organs. Mitral lesions are of more grave significance than those at the aortic orifice, and mitral stenosis is particularly dangerous,! because of its tendency to produce dilata- tion of the left auricle and the heart. Women with cardiac disease of any considerable gravity should be dissuaded, from marriage. The indications for medicinal treatment are the same as for cardiac diseases uncomplicated by pregnancy. Chloroform should be administered with special caution during partu- rition. McDonald, however, believes that, cautiously administered in the second stage, chloroform is useful by diminishing the down-bearing efforts. In order to lessen the latter, the same author urges as of ex- treme importance the timely application of the forceps, or the perform- ance of version in suitable cases, should the second stage be in any way prolonged. The artificial induction of abortion or of premature de- livery is justified only, according to McDonald, in cases where, as in hydramnion, the abdomen is unduly distended. * McDonald, I. c, pp. 199, 200. f Porak, op. cit., p. 113 ; Fbitsch, op. cit, p. 383.

These facts should be remembered by investi- gators of the reciprocal relations between pneumonia and pregnancy, in order that the influence exerted by the former upon the latter be not exaggerated. Pneumonia is an infrequent comj^lication of the pregnant state, but affects the course of the latter very prejudicially * Although a pneumonia of large extent may terminate in complete recovery without having endangered tlie life of mother or foetus,t it often produces abortion or premature delivery, the frequency of these results increasing in direct proportion to the duration of pregnancy. The type of the pulmonary inflammation is also more severe in the later stages of utero-gestation, and parturition exerts an unfavorable effect upon women in proportion as their pregnancy is far advanced.| It was formerly believed that pneumonia, occurring during preg- nancy, owed its fatal character chiefly to the encroachments of the gravid uterus upon the intra-thoracic space, and to the consequent interference with the necessary compensatory increase of functional activity on the part of the healthy lung-tissue. Later investigations having not only shown the fallacy of this theory,* but even rendered jirobable an actual increase in the intra-thoracic space during preg- nancy,! the fatal character of intercurrent pneumonia is referred to coexisting hydremia, and to the inability of the poorly nourished heart to restore the balance of a pulmonary circulation disturbed by the consolidation of lung-tissue and by the consequent impermeabil- ity of large capillary areas. Pulmonary oedema, resulting trom pro- gressive cardiac asthenia, directly induces the fatal issue. Parturition itself, whether naturally or artificially produced, greatly imperils the woman's life"^ by making exorbitant demands upon the already failing heart-power and by aggravating existing hydraemia. Abortion, when occurring under these circumstances, is referred to fetal death caused by deficient oxygenation of the maternal blood, by placental anemia produced through an inadequate supply of blood to the left heart, and by the abnormally elevated maternal temperature.^ From the fatal results of parturition in pneumonia we conclude that the induction of abortion or of premature delivery in ordinary cases is unjustifi- able.J Should labor, however, have already begun, Its termination must be hastened by all available means. Our further treatment must * Pasbexder, Ueber P. als Sehwangersch. Complicat., etc., Beitrag. z.Geburtsh.. hi, 1874, Silzgsber., p. 54. t GussEROw, Pn. b. Schwangeren, Moniitsschr. f.

Brandy and car bonate of ammonia, digitalis and quinia, deserve the most confiden(;e for the fulfillment of these indications. Wernich recommends cautious venesection for tlie relief of extreme dyspnoea or cyanosis, and pro- poses that the collapse to which bloodletting may lead be combated by transfusion.* Emphysema, Chronic Pleurisy, and Empyema.— These affections are dangerous complications of pregnancy, in that they produce cardiac dilatation and prevent the heart from successfully adapting its activity to the varying conditions of vascular tension obtaining in parturition and the puerperal state. The induction of abortion or of premature delivery may be indicated by the existence of these diseases, provided the mother's strength has become so impaired as to incapacitate her for continued utero-gestation. Phthisis. — It was formerly erroneously held that pregnancy afforded immunity against pulmonary phtliisis. This view may have been based upon the clinical fact that the progress of pre-existent phthisis is sometimes retarded by the supervention of pregnancy. f This re- sult is observed, according to Lebert,J in only a small proportion of cases. In the majority of instances, pregnancy not only hastens the progress of actually existing phthisis but precipitates its development. The latter result is of especially frequent occurrence in those heredi- tarily predisposed to the disease, or in such persons as may have re- covered from a previous attack. These effects of pregnancy upon the development and course of phthisis are most manifest between the ages of twenty and thirty years, although they are not infrequent be- tween the ages of thirty and forty. The advanced stages of phthisis prevent conception, but the same is not true of its earlier periods. The puerperal state often favors the development of phthisis, particularly in those hereditarily predisposed to it, and usually hastens the fatal issue of the disease if it has already manifested itself. In very excep- tional instances, however, parturition and the post-partum state exert a favorable influence upon the course of phthisis. It often happens that women with inherited tendencies to phthisis may escape it during their first pregnancy, only to become its victims in a later one.* Al- though women with progressing phthisis may pass through the partu- rient and puerperal states in safety, they are greatly prostrated thereby, and rarely have sufficient milk to nurse their children. They, more- over, often experience abortion or premature delivery. The children of such women are usually puny and feeble. They are slowly and im- * ScHROEDER, Lehrb. d.

Prophy- lactic treatment affords the only encouraging prospects of success in the cases under consideration. Girls with suspected hereditary predis- position to phthisis should, accordingly, not marry, as they should not become mothers. If they do bear children, they must never nurse them. SjrpMlis. — When syphilis, which is a frequent complication of preg- nancy, is contracted at the beginning or during the course of the latter, it is characterized by intense initial and by unusually mild consecutive symptoms.* The duration of the incubation is ordinarily about two weeks, but may be protracted to six weeks. The initial lesions, which are more extensive than in women who are not pregnant, may involve the vagina, cervix, labia, nates, and thighs. They embrace swelling, reddening, and excoriation of the mucous membrane and skin, oedema, eczema, follicular abscesses, and even necrosis of connective tissue. These intense inflammatory processes may be referred to increased nutrition of the parts, and to the mechanical results of friction between them. The secondary symptoms are of a mild type, consisting chiefly of general glandular induration, papules on and around the genitals, and scales on the palms and soles. Mewis f states that the occurrence of parturition has a favorable effect upon these lesions, usually result- ing in their disappearance. Erythema, pharyngitis, alopecia, iritis, and febrile movement are either absent or slightly marked. Pregnant women owe the mildness of their secondary symptoms to amelioration of their general nutrition. Syphilis exerts a very prejudicial influence upon the product of conception. If either parent be affected with general syphilis at the time of the coition resulting in impregnation, syphilis is communicated to the foetus. It is almost equally impos- sible for a foetus poisoned by the paternal reproductive element to infect a healthy mother. Provided the mother were untainted at the time of conception, syphilis contracted by her during pregnancy is rarely communicated to the foetus. If the father be syphilitic, the infection of the ovum is accomplished by the diseased spermatozoids. If the mother be constitutionally tainted, the ovum is already poi- soned. Should both parents be the victims of general syphilis, each equally bequeaths the disease to the offspring. It is probable, too, that the syphilitic poison can traverse the septa intervening between the fetal and the maternal vascular systems. J A progressive and continuous diminution in the intensity of fetal * SiGMUND, Ueber d. Verlauf. d. S. bei Schwangerschaft, Wien. med.

X Professor McLane, of this city, has reported to me the history of a well- observed case, where error was hardly possible, in which the mother, previously healthy, was infected in the fourth month, and gave birth in the ninth month to a dead child with well-marked syphilitic lesions. 272 THE PATHOLOGY OF PREGNANCY syphilis, directly proportionate to the length of time which has elapsed since the contraction of the disease by the parent who communicated it, is observed in cases unmodified by treatment. Parents whose syphilis is allowed to pursue its natural course retain the capability of transmitting the disease to their offspring for varying periods, the average length of which is ten years. Latency of the parental syphilis does not secure immunity of the foetus from the disease. although it diminishes the probability of its transmission. Parents with tertiary syphilitic symptoms may or may not communicate the disease to their children, according as the poison whose original pres- ence produced the gummata is still retained in the system or has been eliminated by nature or by mercurials. In accordance with the varying intensity of the hereditary influence, the foetus may either perish in utero, its death resulting in abortion or premature delivery, may be born alive but destined to die early, or may manifest the dis- ease only at the expiration of periods varying from weeks to months. Conception occurring during the first years after the parents' infec- tion with syphilis almost invariably terminates in abortion or prema- ture delivery, the causes of which are either the vitiated nutritive processes of the foetus, the increased maternal temperature due to syphilitic fever, or syphilitic degeneration of the fetal placenta, con- sisting, according to Mewis,* of inflammatory changes in the tunica intima of the blood-vessels. Similar pathological changes are said, by the same author, to occur in the intima of the umbilical vessels. The pathological conditions observed in syphilitic disease of the placenta are either granular degeneration of the placental villi, with obliteration of the blood-vessels, or the morbid changes designated by the names endometritis placentaris gummosa and endometritis decidualis.f (For a more detailed account of placental syphilis, vide chapter on placental diseases.) Every pregnant woman who at the time of conception is or has been affected with constitutional sypliilis, should be promptly sub- jected to a thorough mercurial treatment, preferably by the method of inunction. This is' desirable even when no present symptoms are detected, with reference to the prevention of the frequently disastrous influences of latent syphilis. If, however, the disease be contracted during the later months of pregnancy, the treatment may consist of palliative measures until after parturition, since no harm will result from the maternal syphilis to the fetal life. Local primary or second- ary disease of the genitals should receive appropriate treatment, in order that the child be not infected during delivery. Chronic Nephritis. — There are few subjects about which so much confusion of thought exists as that of albuminuria in pregnancy. With most it is associated in the mind with eclampsia, and yet * Mewis, loc. cit., p. 42. f Frankel, op. cit., p. 53. ACCIDENTAL COMPLICATIONS. 273 eclampsia in chronic nephritis is a comparatively rare event. (1 :40 ac- cording to Fehling's statistics; 2:70 according to those of Seyfert). It is desirable to differentiate, therefore, the various conditions in which albuminuria develops during pregnancy. Fehling's * researches in this direction have a special value. - In the transitory form in which eclampsia is most apt to occur, the albuminuria develops in the later months of pregnancy. It is as- sociated with an abundance of hyaline and granular casts, and has a tendency to disappear after labor. There is, moreover, no especial dis- position for the albuminuria to return in later pregnancies. In a second group, women who in the non- pregnant state are apparently healthy, or who exhibit only slight traces of albumen in the urine, develop albuminuria from the beginning of pregnancy. In these cases the casts in the urine are scanty, the heart's action is increased in force, there is sometimes oedema, and occasionally the condition is associated with hemorrhages. In most cases death of the fwtus occurs in consequence of placental changes. The amniotic fluid diminishes in quantity, the uterus is arrested in its development, and the albu- minuria disappears in part, or in its entirety. Characteristic of this form is its tendency to recur with each consecutive pregnancy. In still another group of cases the albuminuria is due to chronic Interstitial or parenchymatous nephritis. With pregnancy there is usually an acute exacerbation of the symptoms. Casts and albumen be- come more abundant, oedema develops, albuminuric retinitis is a com- mon complication, and nasal or intracranial haemorrhage may occur. The causes of the increased trouble are attributed to reflex contrac- tion of the arterioles and consecutive ansemia of the unaffected portions of the kidney, and to associated venous congestion resulting from cardiac insufficiency. As regards treatment, Fehling advises to ex- amine the urine frequently, especially if oedema is present. Slight traces should admonish to watchfulness. If the amount of urine exceeds one per cent, woolen underwear should be worn ; the action of the skin should be maintained by tepid baths ; the diet should consist in large measure of milk, and alcohol should be avoided. In severer cases rest in bed, hot baths (98° to 107°), and warm packs often give relief. If, however, there are headache, nose-bleed, heart disturbance, or if no improvement in the number of casts or in quantity of albumen results from treatment, abortion or premature labor is indicated. In chronic nephritis, death of the child from ])lacental changes (white infarctions, according to Fehling) is so common that considera- tions for the life of the child must be always subsidiary to the interests of the mother. * Fehling, Weitere BeitrJige znr klinischon Bedeutung der Nephritis in der Schwangerschaft, Arch. f. Gynaek.. vol., xxxix, ]>. 408. 18 274 THE PATHOLOGY OF PREGNANCY. In chronic nephritis it is not desirable that the kidneys should be subjected to the hazards of a renewal of pregnancy. Diabetes in Pregnancy. — Dr. Mathews Duncan * has called atten- tion to the very serious consequences of diabetes complicating preg- nancy and the puerperal state. But few cases have been recorded. Diabetes may occur during pregnancy, and in some cases during pregnancy only. It may cease after the termination of pregnancy, and may not return in pregnancy after its cure. Pregnancy may occur during diabetes, and in that case may be apparently unaffected in its healthy progress by the disease. In twenty-two pregnancies, occurring in fifteen mothers, four termi- nated fatally. In several, death was by collapse rather than by coma. Hydramnios was frequent, and in one case sugar was found in the fluid. In seven out of nineteen pregnancies, occurring in fifteen mothers, the child died in pregnancy, having in all of them reached u viable age. In two more the child was feeble at birth, and died a few hours after. In one case the child was diabetic. With one exception, all the mothers were multij^arae. Chorea in Pregnancy. — Chorea, which is a rare complication of pregnancy, affects primipars by preference, particularly those possess- ing an hereditary predisposition. Barnes f was able to collect only fifty-six and Fehling I only twelve additional cases from the whole do- main of obstetrical literature. Organic cerebral lesions are assumed by Spiegelberg* as established causes of the disease. In regard to other etiological agencies wide di- versities of opinion prevail. According to Goodell,|| the choreic move- ments are of reflex nature, and are referable to im])aired nutrition of the central nervous system, incident to the hydraemia of pregnancy. The association of chorea and organic cardiac disease has been fre- quently observed, and the discovery in certain cases of fibrous vege- tations upon the mitral and aortic valves accounts for the assumption by some authors of embolism as a cause of chorea. Barnes''' dis- countenances this view, and calls attention to the probable causative agency of myelitis. Terror and other intense emotions may act as exciting causes of chorea. Choreic movements occurring in pregnancy do not differ from those attending the disease in the unimpregnated state. They are usually bilateral. In most cases the muscular contractions manifest themselves in the earlier months of pregnancy, and continue until * Matthews Duncan, On Puerperal Diabetes, Obstet. Trans., vol. xxiv, p. 256. t Barnes, Trans, of the Obstet. Soc. of London, x, 1869, p. 147. X Fehling, Arch. f. Gynaek., vi. 1874, p. 137. * Spiegelberg, Lehrb.. p. 2.5.5. I GooDELL, Am.

In still more exceptional cases the contrac- tions may either cease before delivery or persist during the ^0A^j!>a//7/?/i state. Transitory albuminuria and diabetes mellitus are occasional unexplained complications of chorea gravidarum, and the phosphates and urates of the urine are present in abnormal abundance. Abortion and premature delivery, due to the repeated succussion of the uterus, are of very frequent occurrence. Chorea exerts a prejudicial influence upon the course of pregnancy,* having interrupted it in about one half the recorded cases. Death of the mother resulted in seventeen of the fifty-six cases collected by Barnes. f The lethal termination was usually referable to the ex- haustion consequent upon protracted muscular exertion, or to hemi- plegia secondary to grave cerebral or spinal lesions. The life of the child is less frequently sacrificed, but it is itself often affected with chorea. The treatment consists in the administration of iron and quinine, and the lowering of the reflex excitability by the prolonged use of the bromide of potassium. During the attack, chloroform, chloral, and the subcutaneous injection of morphia are often serviceable. When palliative remedies prove fruitless, in view of the perilous nature of the affection, artificial labor or even abortion is indicated. Relaxation of the Pelvic Symphyses, t — This condition, which con- sists in an excess of the ordinary physiological softening at the jielvic articulations, may permit of such a degree of mobility between tlie pelvic bones as to effectually hinder locomotion. This is usually ac- companied by pains in the ligaments of the joints affected, in the thighs, and in the lumbar region. Its existence is easily recognized. Thus, motion at the symphysis pubis becomes apparent if, with the patient in an upright position, she be made to throw the weight of the body upon each leg in alternation, while the accoucheur holds the sym- physis between the thumb and two fingers placed within the vagina. Motion in the sacro-iliac joint is perceived by seizing the crests of the ilium and getting the patient to move forward. In the recumbent posture movements at either the pubic or sacro-iliac joints may be recognized by means of the vaginal touch, upon extending or flexing the femur. The great relief afforded to all the symptoms in such cases by means of a firm binder makes it most desirable that the possibility of its oc- currence should be always borne in mind where the patient walks with difficulty during the latter months of pregnancy, or subsequent to the * GooDELL, Am. Jour, of Obstet., vol. viii, p. 168. t Barnes, Trans, of the Obstet. Soc. of London, x, 1869. i Snelling, On Relaxation of the Female Pelvic Symphyses, American Journal of Obstetrics, February, 1870; Barker, Puerperal Diseases, p. 192. 276 THE PATHOLOGY OP PREGNANCY. childbed period. The first case I witnessed at the Bellevue Hos- pital was altogether a mystery to me, until the nature of the disabil- ity was pointed out by Professor Barker. The patient was in the last month of pregnancy, had been six weeks in bed, unable to move, though apparently otherwise in perfect health. A rude bandage, constructed of canvas and made to lace in front, furnished a good support, and enabled my patient to stand and move around with- out inconvenience. She had, at the end of gestation, a good confine- ment, and subsequently recovered without a trace of her previous diffi- culty. In childbed a towel-binder is capable of rendering good service. During pregnancy, or during the period of puerperal convalescence, where frequent changes of the bandage are not necessary, Martin's girdle, consisting of a solid metal ring surrounding the whole pelvis, has been strongly recommended. I employ a pair of strong breeches, furnished me by Philip Schmidt, instrument-maker, of this city, which are carefully fitted to the thighs and hips of the patient, and are made to buckle in front and lace behind. The apparatus is light, comforta- ble, and answers every requirement. Surgical Operations during Pregnancy. — Massot* concludes, from the observation of a considerable number of cases, that ordinary surgi- cal operations do not interfere with pregnancy unless they materially and permanently disturb the uterine circulation, or call into activity the uterine muscular force by reflex irritation. Cohnstein f states as the result of his researches, that after operations and injuries preg- nancy reaches a normal termination in 54-5 per cent of all cases. In- terruption of pregnancy was in his cases determined — {a) by the period of pregnancy when the operation took place, occurring more frequently as the result of surgical measures resorted to in the third, fourth, and eighth months ; {b) upon the seat of the operation, result- ing, in two thirds of all cases, from operations upon the genito-urinary organs ; (c) upon the extent of the wound following amputations, ex- articulations, and ovariotomies with great relative frequency ; (d) upon the number of children, occurring in multiple pregnancy with uniform regularity. Age seemed to exert no causative influence. Abortion di- rectly results under these circumstances from reflex irritation, or from fetal death referable to hasmorrhage or to septic poisoning on the mother's part. The prognosis, so far as the mother is concerned, de- pends upon the time when delivery occurs. The mortality ordinarily attending delivery, if at term, is insignificant ; for abortions and pre- mature deliveries it amounts, according to Cohnstein, to thirty-three * Massot, Ueber d. Einfluss trauraat. Einwirk. auf d. Verlauf der Schwanger- schaft, Schmidt's Jahrb., 1874, 164, p. 266. t CoHNSTEix, Ueber chirurg. Op. bei Schwangeren, Volkmann's Samml. klin. Vortr., No. 59, 1873, p. 493. ABNORMAL CONDITIONS OP THE UTERUS. 277 per cent. The most frequent causes of the mother's death are shock peritonitis, septicemia, haemorrhage, and oedema pulraoualis. In ninety cases of minor operations upon the pelvic organs collected by Professor Mann,* of Buffalo, there were twenty abortions and four deaths. They included the removal of a caruncle, of epitheliomata, of condylomata, and of polypi, the opening of cysts and abscesses, the dil- atation of the urethra for stone, the plastic operations upon the vulva, cervix, and vagina, etc. He concludes that during pregnancy the union of denuded surfaces is the rule, that the most risky operations are those upon the rectum, and that vaginal operations are apt to be at- tended by severe hemorrhage, though not otherwise dangerous. In view of the manifest danger from operations of any magnitude, it may be stated as a general law that surgical measures not absolutely indi- cated by the existence of pathological conditions liable to aggravation by delayed interference should be postponed until after confinement. Those morbid conditions, however, whose development is hastened by pregnancy, which threaten the existence of pregnancy, or whose exist- ence offers mechanical obstacles to parturition, must be early subjected to operative interference. This remark applies with special force to carcinomatous growths in any part of the body and to intrapelvic tumors. The time of operation should not coincide with the menstrual epoch of pregnant women, as abortion is more likely to occur at that period.f For a similar reason it is recommended that the third, fourth, and eighth months should be avoided. Massot is of the opin- ion I that anaesthetics, when employed during operations on pregnant women, exert rather a favorable than a prejudicial effect upon fetal life by diminishing reflex irritation. Abnormal Conditions of the Uterus. Double Uterus. — Double uterus occurs under various forms. The uterus and cervix may be double, the vagina remaining single. The double uterus may have a single cervix opening into an undivided vagina. The uterus, although double, may have a single cervix open- ing into a double vagina, the septum beginning at the os internum ; or uterus, cervix, and vagina nay be double throughout. All these forms permit of normal utero-gestation on either side or on both sides simultaneously, provided that each half of the genital canal be sufficiently developed. If, however, the dividing septum ex- tends quite to the vaginal entrance, simultaneous pregnancy in each horn is exceedingly rare.* * Manx, Surgical Operations on the Pelvic Organs of Pregnant Women, Gyna- cological Trans., 1883. f Spiegelberg, Lehrbuch d. Geburtsh., p. 268. t Massot, loc. ciL, p. 267. * Schroeder. Lehrb. d. Geburtsh., p. 376. 278 THE PATHOLOGY OF PREGNANCY. If pregnancy occur in only one side of a double uterus, a decidua vera is developed in the other side, and expelled at the end of preg- nancy. Double uterus is less readily diagnosticated during pregnancy than' after or before it, but is usually recognized with facility. A double vagina is not necessarily indicative of double uterus, but if two vaginae are found, each containing a cervix, the presence of double uterus may be safely assumed. If a double cervix terminate in an un- divided vagina, the uterus may or may not be double. When preg- nancy exists in only one horn the uterine development is manifestly unilateral, and the existence of an unimpregnated half may be de- termined by combined manipulation or by the uterine sound. In cases presenting a double uterus witli a single cervix and vagina, the diagnosis rests chiefly upon unilateral uterine development and de- pression of the fundus and body corresponding to the septum. The form of a double uterus is most plainly manifest during the contrac- tions accompanying and succeeding parturition.* It is still undecided whether double uterus be a cause of abortion and of premature de- livery. Ordinarily, however, the symptoms and course of pregnancy are unaffected by this malformation. The complete functional inde- pendence of the two segments is demonstrated by the fact that in twin pregnancies parturition is frequently not simultaneously accom- plished by them. In the case of unilateral pregnancy, the ratio of head to breech presentations is, according to Schatz, as twenty-one to two. Tedious labor may result in cases of double uterus from uterine atony, referable either to imperfect muscular development of the preg- nant horn, to its deviation from the normal pelvic axis, or to obstruc- tion produced by the unimpregnated horn. Post-purtuni haemorrhage may result from uterine atony or from attachment of the placenta to the septum, whose imperfect development prevents its firm and thor- ough contraction. Anteversion and Anteflexion. — The normal anteversion of the un- impregnated uterus is exaggerated by the increased weight of the gravid uterine body, but this deviation is usually rectified by the grad- ual development and upward movement of the uterus. In exceptional cases the anteversion persists after the fourth mouth, and produces vesical tenesmus, dysuria, or incontinence. No evidences of uterine incarceration are, however, observed, and the comparatively trivial symptoms are relieved by regulating defecation, replacing the fundus, causing the patient to assume the dorsal decubitus, or by adjusting an appropriate pessary. In the later stages of utero-gestation anteversion combined with anteflexion may again occur, and produce the deformity known as pendulous abdomen. It is then chiefly due to the inadequate sup- * Schatz, Mitth. aus d. Leipz. Geb.-Klinik u. Polyklinik. Arch. f. Gynaek., ii, 1871, p. 297. ABNORMAL CONDITIONS OF THE UTERUS. 2^9 port afforded to the uterus by the abdominal parietes. The failure of their sustaining power is referable to their relaxation— which is most marked in multiparae— to separation of the recti muscles, or to the yielding of old cicatrices produced by operations or injuries. The dis- placement is also favored by lordosis of the lumbar vertebrae and by contracted pelvis, which prevent the normal descent of the uterus. In extreme eases of pendulous abdomen, the uterus, having separated the recti, descends, covered by fascia and skin, almost or quite to the knees, and seriously interferes with locomotion. Its pressure also pro- duces ffidema of the abdominal wall, vesical tenesmus, and pain in the distended cutaneous tissues. These symptoms are relieved by repo- sition of the uterus and by the application of a suitable abdominal bandage. Retroversion. — Retroversion, a comparatively infrequent form of displacement in the unimpregnated uterus, usually rectifies itself dur- ing the earlier months of pregnancy. Should spontaneous restitution not occur, the fundus being detained below the promontory until after the third month, the cervix bends upon itself at an acute angle, and the retroversion is transformed into a retroflexion. Retroflexion. — Retroflexion occurs infrequently in women who have not borne children, but often renders sterile those who are thus affect- ed. It is one of the most common uterine displacements in women who have borne children, though it does not in their case, ordinarily prevent conception. AA'hen conception occurs in a retroflexed uterus, the latter usually rises from the pelvis, and assumes a position of ante- version at the fourth month. In many cases, however, the displace- ment produces congestion of the uterine mucous membrane, metritis, and abortion. In still other cases the fundus does not ascend above the promontory at the usual time, and either the sym})toms of retro- flexion with incarceration are slowly developed, or that form of retro- flexion known as partial retroflexion, or retroflexion in the second half of pregnancy, occurs. This consists in the division of the uterine cavity into an anterior and a posterior diverticulum or iiouch. The anterior diverticulum is produced by the more rapid upward develop- ment of the anterior uterine wall, Avhicli is subjected to comparatively slight pressure and contains the larger part of the foetus. The pos- terior uterine wall enters predominantly into the formation of the posterior diverticulum, and usually contains the fetal head. This peculiar form of uterine displacement may be spontaneously rectified during pregnancy, or may persist until delivery, producing no impor- tant symptoms except vesical and rectal tenesmus, with dysuriji and painful defecation. In the latter case it materially interferes with par- turition, inasmuch as the cervix, which is displaced upward and for- ward behind the svmphvsis, is not situated in the pelvic axis, and the posterior diverticulum ' is forced by the uterine contractions against 280 * THE PATHOLOGY OF PREGNANCY. the perinaeum and posterior vaginal wall. Even at this stage Nature may restore the uterus to its normal position ; but, in default of spon- taneous restitution, it must be replaced by forcing up the posterior diverticulum with the hand introduced into the rectum, while the an- terior pouch is displaced downward by pressure upon the abdomen and by traction applied to the cervix ; or, where version is practicable, by bringing down the breech, room may be made for the release of the imprisoned head. Retroflexion of the Gravid Uterus, with Incarceration.— Although this form of retroflexion is usually developed in the gradual manner above described, it may, in rare instances, be rapidly produced by sud- den abdominal compression or concussion. The symptoms, which are in either case essentially the same, differ chiefly in the varying rapidity of their development, and result from the pressure of the displaced uterus upon the intrapelvic viscera and tissues, They embrace dysuria, eventuating sometimes in complete re- tention of urine from urethral compression, vesical tenesmus, incon- tinence of urine, painful defecation, constipation or obstipation, vio- lent sacral and lumbar pains which radiate into the thighs, and in grave cases emesis, with all the other symptoms of ileus Abortion, followed by spontaneous restitution and recovery, may occur even at this stage. Should incarceration, however, persist, violent metritis, parametritis, and peritonitis may lead to a fatal issue. In rare cases, gangrene of the uterus or vagina may be induced. A lethal termina- tion may also indirectly result from pathological processes in the blad- der occasioned by retained and decomposing urine. These morbid processes consist in cystitis, sometimes complicated by diphtheritic and gangrenous inflammation of the mucous membrane and of the deeper vesical tissues, which may lead to septicaemia or to rupture of the blad- der. Death may, moreover, result from passive renal congestion and ursemia. The diagnosis of uterine retroflexion with incarceration is based upon the foregoing clinical history ; the fluctuating abdominal tumor, from which large quantities of urine may be obtained by the catheter or by puncture ; the oedema of the vulva ; the presence in Douglas's cul-de-sac of a tumor presenting the characteristic consistence of uter- ine tissue ; the position of the cervix and meatus urinarius behind the symphysis ; and the distention of the perinaeum by the fundus uteri. The distinction between an incarcerated uterus and an extra-uterine pregnancy is sometimes difficult, necessitating a thorough bimanual examination, aided, in cases of abdominal tenderness, by the employ- ment of an anaesthetic. The replacement of the uterus, which, of course, is the objective point of treatment, should in all cases be preceded by the evacuation of the bladder. This is usually accomplished without much trouble ABNORMAL CONDITIONS OF THE UTERUS. 281 by means of a sharply curved male catheter, and by remembering that the urethra is ordinarily deflected somewhat to one side. Cohnstein states that the introduction of the catheter is facilitated by seizing the posterior lip or the vaginal portion with volsella forceps, and diminish- ing the pressure on the urethra by tractions made in a backward di- rection. Veit,* in an experience of from seventy to eighty cases, found catheterization always practicable. Where intelligent effort is at- tended by failure, puncture is allowable. To this end an aspirator needle — which, however, should not be of too small caliber — should be passed through the abdominal walls at a point about three inches above the symphysis. In practice this operation has thus far proved devoid of danger, though the possible risk from infiltration of urine should act as a check to its rash employment. After emptying the bladder spontaneous reposition may take place. If this does not speedily occur, the patient should be put in the knee-elbow position, and steady pressure should be made with two or four fingers upon the fundus, through the vagina. With a little pa- tience this method rarely fails. E. Martin f reports sixteen cases, in four of which spontaneous reposition followed the evacuation of the bladder, and in eleven reposition was accomplished in the knee elbow position. In my own practice the latter method has so far invariably proved successful. If anaesthesia is -required, the replacement of the uterus should be attempted with the patient in the Sims latero-prone position. Pressure upon the fundus should be exerted by four fingers introduced into the vagina or rectum. Barnes J recommends tilting the fundus to one side, so as to disengage it from the projection of the promontory. It may happen that the first attempt may be only par- tially successful, while a renewal of the manipulation after twelve to twenty-four hours may lead to complete reduction (Veit). In exceptional cases the replacement of the uterus may be prevent- ed by inflammatory adhesions, or by the secondary swelling of the dis- placed organ. The induction of abortion then becomes imperative, either by the ordinary methods or by puncture of the uterine walls. The introduction of a uterine sound or a flexible catheter is rarely practicable. In a case reported by P. Miiller,* where the retroversion was complete, with the fundus upon the perineum and the cervix looking directly upward, Muller resorted to the following ingenious expedient : He cut off the end of a male silver catheter, and then bent the extremity into a hook. Having succeeded in passing the latter * Veit, Ueber die Retroflexion der Gebarmutter in den spateren Scbwanger- schaftsmonaten, Volkmann's Samml. klin. Vortr., No. 170, p, i;j()3. t E.

After twelve hours, during which the catgut was left in situ, the foetus was expelled. If catheter- ization can not be accomplished by either of the foregoing methods, puncture of the uterus with a fine trocar, and with antiseptic precau- tions, has proved a tolerably safe procedure, and, by the withdrawal of a portion of the amniotic fluid, a certain means of provoking abor- tion. Prolapse of the Pre^ant Uterus. — In rare instances the normal pregnant uterus becomes prolapsed during the early months through mechanical violence, and its sudden displacement may lead to abortion through uterine congestion and haemorrhage. Ordinarily, however, procidentia uteri is only observed during pregnancy when it has antedated conception, and it is most frequent in multiparae. A slight prolapse disappears temporarily with the ascent of the uterus. A well- marked procidentia, however, as a result of which a part or the whole of the uterus has been extruded from the vagina, is often attended by symptoms of incarceration terminating in abortion. There is no recorded instance of procidentia in which pregnancy persisted until the time of normal delivery in a uterus lying Avholly without the vagina. Procidentia uteri is simulated by hypertrophy either of the supravaginal or of the infravaginal portion of the cervix. This patho- logical condition is unattended by grave results, unless it lead to rigid- ity of the OS uteri, tedious delivery, and uterine inertia. If excessively developed, however, the portio vaginalis may be transformed into a pulpy, polyp-like mass, which by its constant friction and irritation produces abortion. It should not be mistaken for prolapse of the uterus, as efforts at reposition may produce irritation sufficiently severe to induce premature delivery. Amputation of the hypertrophied cer- vix performed during the third month does not necessarily disturb pregnancy, and is indicated in aggravated cases, because of the possi- ble prejudicial influence of cervical hypertrophy, unmodified by treat- ment, upon utero-gestation and parturition. When prolapse, even of slight extent, exists in a pregnant uterus, the normal ascent of the organ should be encouraged by the avoidance of exertion and by careful regulation of defecation and micturition. In more pronounced cases the uterus must be replaced, and sustained by a suitable tampon Spiegelberg * advises the use of a cotton tampon soaked in glycerin and held in position by a perineal bandage, aiui renewed at short intervals. Caution is necessary in the reduction of the uterus, lest the fundus be caught beneath the symphysis and the procidentia converted into a retroflexion. When incarceration has oc- curred and the parts are much swollen, their volume may be reduced by scarification, after which reposition must be attempted. Should it * Spiegelberg, Geburtshiilfe, p. 278. ABNOliMAL CONDITIONS OF TUE UTERUS. 2>(3 fail, abortion should be induced before the incarceration has irrepa- rably compromised the vitality of the pelvic tissues. Prolapse of the Vagina.— A slight degree of vaginal prolapse occurs more frequently in pregnant women than does uterine prolapse. Cases of more complete prolapse of the vagina are, however, almost invari- ably attended with procidentia uteri. The anterior vaginal wall is usually alone involved in the prolapse, although the posterior wall may descend alone, or both walls become simultaneously prolapsed. This displacement produces traction upon the bladder and rectum, resulting in irritation of these organs and of the vulva. During i)ar- turition, moreover, the prolapsed vagina offers an impediment to delivery, and may therefore be subjected to an amount of pressure in- compatible with the maintenance of its vitality. The treatment con- sists in producing regular alvine evacuations, and in sustaining the vagina with cotton tampons and a perineal band, or with the latter alone. During labor, persistent efforts at reposition of the prolapsed vagina must be made between the pains. Should these attempts prove effectual, the vagina must be- sustained in proper position until the descent of the head has occurred. If reposition be impossible, the forceps must be resorted to in order to prevent the disastrous results of excessive pressure on the vaginal tissues, and traction must be so applied as to avoid injury of the anterior vaginal wall. Hernias of the Pregnant Uterus.— Although hernias of the uniui- pregnated uterus are very rare, they still occur much more frequently than those of the gravid uterus. The most frequent forms under which they present themselves are the umbilical and the ventral. Femoral and inguinal uterine hernias, as well as hernias through the foramen ovale and the great sacro-sciatic foramen, also occur. The sac of a ventral hernia is often formed by the yielding and dilatation of extensive cicatrices in the abdominal wall, such as result from ovari- otomies and gastrotomies, or by the separation of the recti muscles. Femoral and inguinal uterine hernias are either congenital or are produced by ovarian or omental hernias, between which and the uterus adhesions exist. Pregnancy has been observed to occur most frequently in inguinal uterine hernias, next in umbilical, and least frequently in femoral hernias.* It has never been discovered in a uterus which had escaped through the foramen ovale or the greater sacro-sciatic foramen. Pregnancy occurring in inguinal or femoral uterine hernias is uni- formly terminated by abortion or by premature delivery. The diag- nosis is readily made if due regard be paid to the absence of the uterus from its natural situation, to the shape and consistence of the hernial tumor, to the physical signs furnished by auscultation and percussion over it, and to the displacement of the vagina toward the site of the hernia. * SPIE(!KLBKR(i. Cifburtsli.. p. '280. 284 THE PATHOLOGY OF PREGNANCY. When the hernia is recognized at an early date, the uterus must, if possible, be restored to its normal position, and there retained by an appropriate truss. Should attempts at reposition be unsuccessful, artificial abortion should be induced, as it will otherwise occur spon- taneously at a later date, and under less favorable conditions. When the product of conception has already attained a large size, reposition and delivery, whether spontaneous or artificial, are rarely accomplished unless the constricting hernial ring be previously divided. Even the latter procedure may prove ineffectual, in which case hysterotomy is the last resort. CHAPTER XV. DISEASES OF THE DECIDUA.— DISEASES OF THE OVUM. Endometritis decidua : 1. Chronica; 2. Tuberosa; 3. Catarrhalis. — Anomalies of the placenta. — Anomalies of form ; of position ; of development ; of circula- tion. — Placentitis. — Degenerations. — Syphilis. — Anomalies of the amnion and of the amniotic fluid. — Hydramnion. — Deficiency of amniotic fluid. — Anomalies of the umbilical cord : torsion ; knots ; hernias ; coiling of the cord ; cysts ; stenoses of vessels ; marginal implantations. — Hydatidiform mole. Endometritis decidua. — The normal congestion of the uterine mu- cous membrane attendant upon conception, and resulting in the forma- tion of the decidua, may, under the irritating influence of various exciting causes, develop into endometritis. The inflammation may be either acute in character, as is often tlie case in cholera Asiatica and other infectious diseases,* or may pursue a chronic course, presenting itself in the three distinct forms about to be considered : L Endometritis decidua chronica diffusa. — The causes of this form of endometritis are not usually readily discoverable. It is believed to be sometimes developed from an endometritis antedating conception. It is also referred to syphilitic infection,! to excessive physical exer- tion, J and to secondary inflammation resulting from the death of the foetus and its retention in the uterine cavity.** The anatomical changes characteristic of this form of endometritis consist essentially in thickening and induration of the decidua, due to a more or less diffuse development of new connective tissue, and to proliferation of the decidual cells. Cysts have been observed in the hypertrophied decidua by Hegar and Maier.|| Kaschewarowa dis- * Slavjanksy, Arch. f. Gynaek., iv, p. 285. t Prankel, Arch. f. Gynaek., v, 1873, p. 53.

DISEASES OP THE DECIDUA. 285 covered newly developed and liypertrophied involuntary muscular fibers in the substance of the decidua.* Extravasations into the hyper- trophied decidual tissue are of frequent occurrence.! The decidua vera or the decidua reflexa may be separately or Jointly involved in these pathological processes, and may be affected throughout a part or the whole of their extent. When the hyperplasia of the mucous membrane is developed in the later months of utero-gestation, pursues a notably chronic course, is limited in extent, or does not .involve the placental decidua, pregnancy may proceed to a normal termination. When, however, the endometritis appears early, assumes an acute or hjemorrhagic type, is attended by partial separation of the decidua, or involves the placental decidua, it frequently induces abortion or i)re- mature delivery, either by causing the deatla of the foetus through in- terference with its nutrition J or by exciting reflex uterine contrac- tions. Parturition may, in either case, be protracted by the slow separation of the decidua, between which and the deeper uterine tis- sues adhesions have been formed by the newly developed connective tissue and muscular fibers. If the placental decidua be involved in the morbid process, the placenta may be separated with difficulty, and its slow expulsion be attended by copious haemorrhages. Another con- sequence of the hyperplasia of the decidua in the later months of pregnancy, according to Kaltenbach,* consists in the non-separation of the decidua vera at the time of parturition. The thickened mem- brane is either rapidly detached after childbirth, forming a sac to which blood coagula adhere, and which in turn become the occasion of haemorrhage, or it is slowly eliminated, giving rise to a putrid discharge, and furnishing materials for auto-infection. He advises, therefore, in cases of syphilis in either parent, that a careful examina- tion be made of the membranes at childbirth, and, if no traces of the decidua are to be found upon their surface, to introduce the hand into the uterus, and to remove retained portions ; or, should this not be done, to promote their expulsion by ergo tin, and to employ prophylactic antiseptic injections. II. Endometritis decidua tuberosa et polyposa.— The etiology of this variety of decidual inflammation is involved in obscurity. Syph- ilis was regarded as a causative agent by Virchow, who first described the degenerative changes under consideration,! and pre-existent endo- metritis is also supposed to occupy a causative relation to them. Gus- serow^ suggests that conception occurring soon after delivery may * Kaschewarowa, he. cit., p. 111. f EiGENBROD und Hegab, Monatsschr. f. Geburtsk.. vol. xxii, 1863. {>. 161. I Klebs.

It is doubtful whether the latter are ever secondary to irritation produced by the death of the foetus.* In Ahlfeld's cases the inflammation was apparently idiopathic. The pathological processes peculiar to this variety of endometritis are usually observed in the decidua vera alone, and manifest a jirefer- ence for those portions of the decidua corresponding to the anterior and posterior uterine surfaces. In some cases, characterized by absence of the decidua vera, the decidua reflexa is found involved in the mor- bid changes. The latter consist in marked thickening of the entire decidua referable to proliferation of the interstitial connective tissue and to extensive hypertrophy of the decidual cells, which are provided with nuclei of enormous size. Occasional free nuclei occur. f The uterine surface of the decidua is rough and covered with coagulated blood, while the entire mucous membrane is exceedingly vascular. Upon that surface of the decidua which is directed toward the ovum are situated large excrescences or elevations, the prevailing shape of which is polypoid. They may, however, appear in the form of nod- ules, of cones, or of boss-like projections provided with a broad, non- pedunculated base. Their height is from one quarter to one half an inch, and their surface is smooth, very vascular, and devoid of uterine follicles. The latter are, however, plainly visible on the mucous mem- brane intervening between the polypoid outgrowths, but they are com- pressed and their orifices constricted or obliterated by the pressure of Avhitish, contracting bands of newly developed connective tissue. Similar fibrous bands surround the blood-vessels. On section, the larger prominences sometimes appear permeated with coagulated blood, and narrow, cord -like bands of hypertrophied decidual tissue occasion- ally form bridge-like connections between neighboring polvpi. The uterine follicles are in some cases filled with blood-clots. The epi- thelium is often absent from the uterine surface of the decidua except around the orifices of the follicular glands,J and the deeper decidual tissues contain large numbers of lymphoid cells. The cells of the decidua reflexa frequently undergo fatty degeneration. The placental villi may show hypertrophy of their club-shaped ends, or be the seat of myxomatous growths, in which case their cells are granular and cloudy. The fa?tus is generally dead and partially disintegrated. This form of endometritis decidua is consequently usually accom- panied by abortion, which occurs predominantly at an early stage of pregnancy. III.

DISEASES OF THE OVUM. 287 ties just described, affects pluriparae more frequently than primiparae, and seems to stand in etiological relations with hydrsemia. The pathological processes involved in the disease are vascularity, hyperse- mia, and hypertrophy of the interstitial connective tissue and of the glandular elements of the decidua. The inflammation involves the decidua vera by preference, but may simultaneously affect the de- cidua refiexa. The most striking symptomatic occurrence is due to the glandular hypertrophy, and consists in the escape from the uterine cavity of a thin, watery, muco-purulent or sero-sanguinolent liquid, which resembles the amniotic fluid both in color and in odor. Pro- vided that free exit be afforded to the secretion, its discharge is affected gradually and in small quantities. Should, however, obstacles to its continuous evacuation be encountered, either in the usual adhesions between the decidua vera and reflexa or in impenetrability of the os internum, the secretion, having accumulated between the decidua and the chorion, forces a passage through the decidua reflexa and is dis- charged in considerable quantities. In some cases even a pound or more of the liquid is thus suddenly evacuated. Small quantities of the secretion are often observed as early as the third month. The more abundant discharges occur only in the later periods of pregnancy, and are often attended by slight uterine contractions, which may, in exceptional cases, become so severe as to induce abortion or premature delivery. The diagnosis involves differentiations between a discharge emanat- ing from the hypertrophied decidual glands and the ante-'partwii es- cape of a fluid which sometimes accumulates between the amnion and chorion. The latter discharge, the quantity of which may be so large as to stimulate hydramnion, differs from that of hydrorrhoea gravi- darum in that it occurs only once.* The escape of the decidual secre- tion might be mistaken for that of the amniotic fluid, which may be easily distinguished by the fact that the latter immediately precedes delivery. The treatment should embrace analeptic and tonic measures, as well as the careful avoidance of vaginal douches and of all local irritation tending to produce abortion. Should uterine contractions accompany the escape of the decidual fluid, appropriate anodyne treat- ment must be adopted. Anomalies of the Placenta. 1. Anomalies of Form.— The usually round or oval placenta may be of a horseshoe or other irregular shape. The superficies depends upon the extent to which the villi form vascular connections with the de- cidua. In general terms it may be stated that the thickness of the placenta is in inverse proportion to its surface extension. PlacentaB * Spiegelberg. Of. cit.. p. 303. 288 THE PATHOLOGY OF PREGNANCY. succenturiatae, small accessory placental developments, are due to the persistence of isolated villous groups, which form vascular connections with the decidua vera. Placentas spuria? consist of circumscribed de- velopments of villi, the decidua not participating in the growth. A placenta membranacea is a broad and thin vascular membrane pro- duced by a diffuse proliferation of the villi over the entire ovum, form- ing vascular connections with the reflexa, or, where the latter is absent, with the vera. 3. Anomalies of Position. — The placenta may be attached over the OS internum, thus constituting placenta praevia, over the orifice of the Fallopian tube, or in connection with extra-uterine pregnancy, at vari- ous points in the abdominal cavity. 3. Anomalies of Development.— A hypertrophied placenta is ab- normally large in proportion to the size of the foetus, occurs chiefly in connection with hydramnion, and consists of a genuine parenchym- atous hyperplasia. A small placenta is referable either to defective development, to premature involution, or to hyperplasia of the connect- ive tissue, with subsequent contraction.* 4. Anomalies of Circulation. — Haemorrhage into the placenta is sometimes produced by congestion of the utero-placental vessels, due to disturbances in the motlier's vascular system, f The extravasation may, rarely, be intraplacental, may occur into the serotina, thus con- stituting utero-placental apoplexy, or may take place into the uterine sinuses. In the last case, thrombosis of the placental sinuses is said to have occurred. J Placental haematomata are the above-mentioned collections of coagulated blood in various stages of disintegration. The causes of the haemorrhage are chiefly morbid changes in the decidual vessels^ often referable to placentitis. The extravasated blood usually experiences the ordinary retrogressive metamorphoses. It sometimes undergoes cystic, fatty, or calcareous degeneration. The pressure upon the villi produced by the haematomata impairs the nutrition of the foetus, and may cause the death of the latter. (Edema of the placenta, a morbid condition usually attributed to derangement of the fetal or umbilical circulation, is characterized by abnormal pallor, with increased size', friability, and succulence of the placenta, due to serous infiltration. The morbid anatomical changes consist essentially in cystic dilatation in and between the villi, accom- panied sometimes by extravasations. 5. White Infarctions of the Placenta. — This term is applied to thickenings of the placental tissue, varying in color from a yellowish red or yellow to a dirty or grayish white. They have a dense struct- ure, are moderately firm in young infarctions, with more of a fibrous * Whitaker, Am. Jour, of Obstet, August, 1870, p. 229. t Nouv. Diet, de Med. et de Chirurg.

In size they vary from that of a beau to that of an English walnut. For the most part they are sharply circum- scribed ; sometimes flattened, sometimes oval or rounded or wedge- shaped. In some cases the infarctions send out radiate processes. More frequently they are found upon the maternal surface of the pla- centa. They do, however, form on the fetal side. They may extend through from surface to surface, or may be imbedded in the placental substance. These so-called infarctions apparently are due primarily to a hyaline degeneration of the decidua. The same process extends to the de- cidual vessels, and thence to the intervillous spaces. In these a coagu- lation of the blood takes place. The ensuing compression exerted upon the fetal villi leads to their necrosis and obliteration.* Fehling believes that rupture of the maternal vessels due to endarteritis may likewise serve as the primary cause of the compression and necrosis of the villi. White infarctions are present in nearly every placenta. AVhen few in number and of small size, they are innocuous. In syphilis, in endo- metritis, in nephritis (Fehling), etc., they may lead to extensive destruction of placental tissue, and are the most frequent cause of the intra-uterine death of the foetus. 6. Degenerative Changes. — (a) Fatty degeneration of the placenta, circumscribed or diffused, may result from retrograde changes in ex- travasations. When developed early in pregnancy, it is sometimes re- garded as a premature completion of the fatty degeneration normally occurring at the end of pregnancy, and may be due to syphilis or scrofula, (b) Amorphous calcareous deposits are frequent, and are almost invariably found on the uterine placental surface, in the decidua serotina. Thence the process may extend to the fetal portion of the placenta. When the calcareous change begins in the fetal tissues it is confined to these, and affects the small blood-vessels of the villi, be- ginning in their terminal ramifications and gradually involving their trunks, (c) Pigment deposits, resulting usually from alterations in the hasmoglobin of extravasations, are found in both healthy and diseased placentae within the blood-sinuses or villi. {(I) Cysts are of frequent occurrence in the placenta. They are found near the center of its concave surface, and vary from a few lines to several inches in diameter. The cyst-wall is covered by the protruding surface of the amnion. The fluid in the cysts contains albumen and mucin. Fenoinenow f regards these cysts as the product of the placental villi. The latter, he sup- poses, in consequence of irritative changes, swell and undergo a partial * For resume of literature of the subject with recent observations, vide Jacob- sohn, Untersuchungen uber die Weissen Infarcte der Placenta, Ztschr. fiir Geb. und Gynaek., vol. xx, p. 237. f Fenomenow; Zur Pathologie der Placenta.

The fluid he regards as an excessive physiological secretion from that portion of the epithelium which remains intact upon the villi. 7. Syphilis of the Placenta.— In placental syphilis the placenta is pale and heavy, often equaling one third of the weight of the fretus. It only exists, according to Frankel,* in connection with congenital or hereditary fetal syphilis. It involves the maternal portion of the pla- centa, when the mother was infected either before or soon after con- ception, and produces gummatous proliferation of the decidua, charac- terized by the development of large-celled connective tissue, with occa- sional accumulations of younger cells. When the infection is conveyed by the father to the foetus alone, or to both mother and foetus, pathological changes occur as the result of a chronic inflammatory process, embracing proliferation of the cells and connective tissue in the villi, with subsequent obliteration of the vessels, often complicated by the marked proliferation and hardening of their epithelial covering. The affected villi become swollen, cloudy, aud thickened, while their epithelium undergoes proliferation and cloudy swelling. The parenchyma of the villi is filled Avith lymph-cells, and the vessels are either compressed or obliterated. The blood-sinuses are gradually encroached upon by the villi, the foetus dies from lack of adequate nutrition, and the villi undergo fatty degeneration. Portions of the healthy placental tissue, which often intervene between the diseased parts, may be the seat of extravasations. Anomalies of the Amniox and of the Amniotic Fluid. I. Hydraxnnion. — Inasmuch as the amount of the liquor amnii va- ries considerably within normal limits, the term hydramnion should be restricted to those cases in which the amount of fluid is so large as to produce morbid symptoms by its pressure upon the uterus, the abdominal and thoracic viscera. When the quantity exceeds tAvo to three pints, inconveniences are often experienced. It is, hoAvever, usually only when the higher degrees — viz., five pints and upAvard — are reached that the symptoms possess such an intensity as to constitute a special malady. It is customary to distinguish an acute and a chronic form — in the former a rapid increase in the size of the abdomen taking place in a few days, or even, as in a case reported by Sentex, in a single night; whereas in the latter the progress is slow, extending over months, and occasioning infinitely less disturbance of function. Etiology. — The causes of hydramnion are hardly to be found in a * FrXnkel, Arch. f. Gynaek., v, 1873, p. 52. DISEASP^S OF THE OVUM. 291 single morbid condition. In a limited number of cases— and this h especially true of the rare acute form, though even in these not in all reported instances— tlie excessive production of fluid was found to be associated with inflammation of the amnion. In by far the largest proportion of cases, however, the evidence is strong that the excess of fluid is of fetal origin. Sallinger's * experiments show that when a liquid is injected into the umbilical vein it transudes witli great rapidity into the amniotic sac, and that the amount of transudation is proportioned to the pressure exerted, and to the size of the cord. Jungbluth described, during the first half of pregnancy, a capillary network (vam propria), connected with the vessels of the umbilical cord, developed just beneath the amnion, in that portion of the cho- rion which covers the placenta. Levison f found that this capillary network was persistent at term in hydramnion, but not in nornud pregnancy. Between these vessels and the inner surface of the am- nion, canalicular spaces furnished a series of communicating passages. Lebedjew X concluded that in certain abnormal conditions of the fa'tus found associated with hydramnion the capillary network of Jung- bluth was persistent to the end of pregnancy. With these anatomical conditions an increased secretion, due to stasis in the vasa j^ropria, would result from any condition causing stenosis of the umbilical vein, from obstructions to the hepatic circulation, and from diseases of the fetal heart and lungs. In this connection it is proper to observe that syjDhilis, and especially syi^hilitic affections of the liver, are frequently associated with hydramnion. Charpentier found that, in one hundred and twenty-three cases of multiple pregnancy, fifty- two were cases of hydramnion. Kiistner,* Schatz,|| and Werth^ have recently drawn attention to the occurrence of hydramnion affecting one amniotic sac only in twins developed from the same ovum — i. e., with a single chorion, the sac of the second foetus containing less than the normal quantity of fluid. In all these cases^ in the foetus contained in the hydramniotic sac both heart and kid- neys were hypertrophied, and the amniotic fluid contained an unusual amount of urea. The cardiac hypertrophy Kiistner ascribes to the appropriation by the stronger fcetus of the placental territory, which in twin pregnancies from a single ovum is primarily common to both foetuses. The increased work thus entailed upon the heart leads to a thickening of its Avails, which in turn is followed by increased growth and activity of the kidneys. In Kiistner's cases there was likewise * Sallinger, Dissert. Inaugural, Zurich, 1875. f Levison, Summary in Arch. f. Gynaek., vol. ix, p. 517.

AVertli suggests that the activity of the fetal cir- culation leads to more active absorption on the part of the placental villi, and that the insufficient action of the kidneys, in their attempt to maintain the necessary equilibrium in the fetal circulation, explains the outpouring of fluid not only into the amnion but into the serous cavities of the fcetus, as is often observed in bydramnion. The question as to how far the amniotic fluid may be of maternal origin is still an undecided one. Ahlfeld and Leopold maintain that serum may pass through the pores in the chorion and amnion from the vessels of the decidua reflexa (and later from those of the ova) directly into the amnion. Zuntz, Wiener, and Bar state that substances experi- mentally injected into the maternal veins may be found in the amni- otic fluid Avithout having first traversed the body of the foetus.* Symptoms and Signs.— The distention of the uterus, and the conse- quent abnormal expansion of the abdomen produced by hydramnion, results in an impediment to locomotion, and causes discomfort or actual pain by traction upon the abdominal parietes. The diaphragm is forced upward, and, encroacliing upon the thoracic space, compresses the lungs and displaces the heart, thus producing dyspncea and car- diac palpitation. The urine may become scanty and albuminous from impeded renal circulation. Neuralgic pains and redema of the abdomi- nal walls, of the labia and lower extremities, are produced by com- pression of the pelvic nerves and vessels. Vomiting and dyspeptic aymptoriis result from direct compression of the digestive organs or from reflex irritation of them. Ascites may be produced by obstruc- tion of the portal circulation. Insomnia results from the patient's general discomfort and the deterioration of her health. In the acute form, vomiting is often incessant, the pain is intense, and febrile symp- toms develop. Physical examination reveals in advanced cases an im- mensely distended abdomen. The uterus, which can be easily mapped out by palpation and percussion, is tense, elastic, and obscurely fluctuating. The fetal cardiac sounds are faint or imperceptible. The foetus changes its position with unusual rapidity and facility. Combined manipulation shows the lower segment of the uterus to be elastic and tense, while the foetus can not be readily felt by the finger placed in contact with the cervix. Pregnancy accompanied by hy- dramnion seldom reaches its normal termination, delivery being pre- maturely induced by death of the foetus, by separation of the placenta, or by overdistention of the uterus. The first stage of labor is abnor- mally prolonged, because of the comparatively feeble contractions of the expanded uterine walls. Labor may become precipitate in the second stage, owing to the sudden escape of the amniotic fluid ; and uterine inertia, in the third stage, frequently results in post-partum liEemorrhage. Involution is apt to be protracted and incomplete. * Vide Charpentier, Traite pratique des accouchements, p. 890. DISEASES OF THE OVUM, 293 Diagnosis.— Hydramnion may be mistaken for twin pregnancy, but is easily excluded by the rational symptoms, by the tenseness of the uterine walls, by the feebleness or absence of fetal heart-sounds, and by the difficulty experienced in perceiving the foetus on palpation. Prognosis.— The prognosis for the child is fatal in nearly one fourth of the cases. For the mother it is favorable, although the risk of po-sf- jmrtum haemorrhage is considerable. This high mortality is due to malformations of the foetus, to dropsical affections, to prematurity, and to the frequency of faulty presentations. Thus, of one hundred and thirteen cases collected by Charpentier, twenty-one presented by the breech, twenty by the shoulder, and two by the face. Treatment. — The treatment embraces the application of an abdomi- nal supporter and the injunction to refrain from active physical ex- ertion. Grave disturbances of the mother's heart indicate the induc- tion of premature delivery, which should, hoAvever, in the interest of the child, be delayed as long as is consistent with maternal safety. In parturition, the membranes should be punctured if the accumulated liquor amnii retards the dilatation of the cervix. Puncture must be performed in the interval of the jiains, in order that the waters may escape gradually and leave the position of the child unchanged. After the expulsion of the placenta, the usual prophylactic measures against post-2)arf/nii hemorrhage must be promptly adopted. II. Abnormally Small Amount of Amniotic Fluid. — The quantity of amniotic fluid may, even in some cases of advanced pregnancy, be so limited as to render the uterus unusually small and firm, and to limit the freedom of the movements. Under these circumstances, the movements are so plainly perceptible to the mother as to be the source of positive discomfort. An abnormally small quantity of liquor amnii is, however, only of importance in the earlier stages of fetal development. If the amnion be not then separated from the fatus by an adequate amount of fluid, abnormal amniotic foldings and adhesions between the amnion and the surface of the foetus may take place. The so-called foeto-amniotic bands * thus formed may, by mechani- cal compression, result in various fetal deformities, or in spontaneous intra-uterine amputation. AXOMALIES OF THE UMBILICAL CORD. I. Torsion. — Torsion consists in such a rotation of the umbilical cord upon its longitudinal axis that its vessels are thereby rendered nearly or quite impermeable. It occurs most frequently in foetuses which have advanced beyond the middle period of normal utero-gesta- tion, particularly, according to Spiegelberg,t in those of the seventh * PuRST. Arch. f. Gynaek., Bd. ii, 171. p. :U8. ■f Spiegelberg, LehrV)uch, p. 'SHO. 294: THE PATHOLOGY OF PREGNANCY. mouth. It is, however, often met with in fcetuses of an earlier age. Until a comparatively recent period, authors have unreservedly attrib- uted torsion to active movements on the part of the feftus, and re- garded it as the cause of the latter's death. Martin * has shown that this theorv is untenable for the majority of cases, because the patho- FiG. 131.— Torsion of the cord. (Schauta."* logical conditions which result from fetal death induced by torsion, whether rapidly or slowly produced, are almost invariably absent. These morbid anatomical processes embrace rupture of the umbilical blood-vessels, and extravasations, for cases of sudden origin, and con- gestion, with oedema, for those more gradually developed. Martin * Martin, Ztschr. f. Gebnrtsh. ii. Gynaek.. Rd. ii. Heft 2, 1878, p. 346. DISEASES OF THE OVUM. 295 therefore concluded that torsion was o. post-mortem event, resulting from rotation of the foetus produced by maternal movements. Ruo-e* earnestly advocated the same view, and suggested the various morbid changes due to syphilis, endometritis placentaris, and sub-placental hemorrhage as the cause of fetal death in cases which subsequently developed numerous torsions. Schauta \ appears as a recent champion of the same theory, although he admits that loose torsions, incapable of producing actual stenosis of the umbilical vessels, may often occur during the life of the fcetus. He bases his belief in the post-mortem occurrence of torsion — 1. Upon the large number of twists often pre- senting themselves, any one of which would have involved the death of the foetus. Even granting the original torsion to have been of ante- mortem origin, the others must then have occurred after death. 2. Upon the improbability of the formation of very numerous torsions in a healthy cord, inasmuch as its elasticity would lead to comj^ensatory reverse rotation. 3. Upon the fact that even twenty-five artificially induced torsions resulted in rupture of the normal cord from excessive tension. Schauta regards the cysts found in connection with some torsions as insufficient proof of their ante-mortem occurrence. Tor- sions are more frequently present in the umbilical cords of male than in those of female foetuses, and are sometimes surprisingly numerous. Schauta reports a case in which he observed three hundred aud eighty rotations of the cord on its longitudinal axis. It occurs by preference in multiparae, probably on account of the greater latitude afforded for fetal movements. Unusual length of the cord favors its occurrence, for a similar reason. The seat of the torsion is ordinarily in close proximity to the umbilicus. It occurs but rarely at the placental end or in the center of the cord. The umbilical vessels are usually nearly occluded at -the seat of the torsion, but still permeable. Thrombi of varying consistency are often found in the ves- sels. Sero-sanguinolent fluid in the ab- dominal cavity of the foetus, oedema, and cystic degeneration of the cord, are also pathological conditions frequently at- tending torsion. II. Knots. — Knots in the umbilical cord, which occur once in two hundred ^ , .,. , Fig. 132.— Knot of umbilical conl. cases, may result from the passage oi the iLeyman.i foetus through a twisted loop of the cord, whether the passage be effected during pregnancy by the spontaneous fetal movements, or at term by the uterine expulsive efforts, or by the manipulations of the accoucheur. Knots formed during parturition * RuGE, ihid., Bd. iii, Heft 2, 1878, p. 417. f Schauta, Arch. f. Gynaek., Bd. xvii, Heftl, 1881. p. 20. 296 THE PATHOLOGY OF PREGNANCY. are loose and easily untied. They are unattended by any diminution in the gelatin of Wharton. Those occurring during pregnancy are more closely and firmly drawn, and more difficult to loosen than the former variety. The cord is partly or completely denuded of the gelatin at the seat of the knot, and plainly shows the location of the latter, after its solution, by well-marked indentations. Knots in the cord, of either variety, are comparatively insignificant, although a tightly contracted one, in a thin cord, may occasion grave or even fatal disturbance of the ujnbilical circulation. III. Hernia. — Hernia of the umbilical cord consists in the escape from the abdomen, at the point of insertion of the cord, of some or all of the fetal abdominal viscera. It is due either to arrested embryonic development, which prevents the complete closure of the abdominal cavity, or to the failure of the fetal intestines, originally situated out- side the abdomen, to enter the same. Hernia of the cord may occur alone, in otherwise normally developed foetuses, but is usually accom- panied by other deformities, such as stricture of the rectum, imper- forate anus, or distortions of the lower limbs and of the genitals, pro- duced by traction of the displaced viscera upon adjoining parts. The contents of the hernial sac, which is composed of the amnion and of the peritouiBum, are usually convolutions of the intestine, or these with a portion of the liver, although the kidneys, stomach, and sjDleen are sometimes also extruded, leaving the fetal abdomen nearly empty. IV. Coiling of the Cord. — Windings of the umbilical cord around the foetus, occurring during pregnancy, vary in their results with the rapidity of their formation. When rapidly developed, they may in rare cases lead to sudden interruption of the umbilical circulation, and to consequent death of the foetus. Should the coils be gradually formed and firm, the extremity embraced by the cord increases, by its own growth, the tightness of the constricting ligature. The latter slowly lessens the caliber of the vessels supplying the extremity con- cerned, and finally, occluding them, produces death of the limb. Ab- sorption of the soft and hard parts of the extremity may result from the cord's unyielding pressure, and the limb be thus completely severed from the trunk by so-called spontaneous amputation. In cer- tain cases the combined pressure of the cord and of the slowly grow- ing member may suffice to completely arrest the umbilical circulation, and thus produce the death of the foetus. Should the neck be encir- cled by the cord, death may ensue from strangulation, and be followed in some cases by almost complete amputation of the head. Coilings of the cord around the foetus occurring at birth are of little impor- tance unless they be numerous. In that case they lead to a shorten- ing of the cord, and produce anomalous positions, premature separa- tion of the placenta, retarded second stage of labor, and even death of the foetus from interference of the umbilical circulation. DISEASES OF THE OVUxM. 297 V. Cysts.— Cysts of the umbilical cord within the amniotic sheath are either produced by liquefaction of mucoid tissue, or by accumula- tion of serum between the epithelial layers of the allantois. VI. Stenosis of Umbilical Vessels.— Partial occlusion of the um- bilical vein at the placental insertion, produced by new connective tissue resulting from circumscribed periphlebitis, is sometimes ob- served, but is not sufficiently marked to impede the umbilical circula- tion. Stenosis of the umbilical arteries is occasionally produced by atheroma and subsequent thrombosis. Stenosis of the umbilical vein, Fig. 133.— Insertio velamentosa. (Lobstein.) and, more rarely, of the arteries, may also result from chronic phlebitis characterized pathologically by the growth in the intima of spindle- shaped and round cells, which later develop into new connective 298 THE PATHOLOGY OP PREGNANCY. tissue. This process, whicli is usually referred to hereditary syphilis * may extend into the muscularis, and even invade the adventitia. The result of the stenosis of the uterine vessels is, of course, prejudicial to the foetus in direct proportion to its grade of development. VII. Calcareous Degeneration.— Calcareous deposits have been ob- served in the cords of syphilitic foetuses. VIII. Marginal Insertion of the Cord.— This anomaly is sometimes called the battledoor placenta, while the term iiisertio velamentosa is applied to cases where the vessels of the cord pursue their course for some distance through the membranes before reaching the placenta. To comprehend their origin, it is necessary to recall the main physio- logical processes involved in the normal development of the placental organ. The vessels of the allantois are not invariably carried at the outset to the point in the periphery of the ovum which the placenta will ultimately occupy. The vessels at first penetrate all the villi in- discriminately, but as the process of obliteration advances in those villi not destined to participate in the formation of the placenta, vas- cular connections are only preserved between the vessels of the newly formed cord and the villi attached to the serotina. As the amniotic sheath forms around the rudimentary cord, the foetus performs a movement of rotation in such a way that the umbilical vessels are made to pursue a direct course toward their placental insertion. If, owing to the adhesions between the rudimentary cord and either the chorion or the amnion, the formation of the sheath is incomplete, the vessels diverge, and are distributed to points more or less distant from the placenta (Schultze). In the insertio velamentosa (Fig. 133), hgemorrhage sometimes results from a rupture of a vessel at the time of the breaking of the membranes — an accident which, unless speedily followed by delivery, is apt to prove fatal to the foetus. IIydatidiform Mole. I. Morbid Anatomy. — Before the time of Cruveilhier, who is said to have first demonstrated the difference between true hydatids and the uterine hyd; tidiform mole, these morbid formations were regarded as identical. Since his researches, it has been considered established that the essential pathological process involved in the production of the hydatid mole consists in a proliferative degeneration of the chori- onic villi. This degeneration of the villi embraces h^'pertrophy of their investing epithelium, of their connective-tissue cells, which may also undergo mucoid degeneration, and of their mucoid intercellular substance. The accumulation of the mucoid tissue imparts to the villi the appearance of cysts with translucent, semi-fluid contents, varying in size from that of a millet-seed to that of a walnut, and forming, by * Mewis. Ztschr. f. Geburtsh. u. Gynaek., Bd. iv, Heft 1, 1879, p. 62. DISEASES OF THE OVUM. 290 their aggregation, growths which may attain the dimensions of a child's Jiead, or in rare cases may reach such proportions as to distend the uterus to the size usual at the full term of pregnancv. Smaller collec- tions are much more frequently encountered than those of these enormous proportions. The fluid of the cysts is albuminous, and closely resembles the liquor amnii, but contains in the earlier stages a larger proportion of mucin than the latter. At a later period the mucin is less abundant, while the albumen increases in quantity. The larger cysts are richer in water, but contain less mucin than the smaller ones. Inasmuch as the degenerative process does not attack the entire villus, portions of normal tissue intervene between the cysts, and impart to tlie degenerated mass the appear- ance of grape-clusters — the cysts i-epresenting the individual berries, and the unaltered tissues their con- necting stems. A certain number of cysts are, however, attached to a single continuous pedicle, instead of possessing a separate stem con- nected with a common trunk, as is the case in the grape-cluster. If the mole be formed, as is usually the case, during the first month, while the villi are equally devel- oped upon the entire perij^hery of the ovum, the degeneration will involve its whole surface. In this case the foetus, dying and becoming disintegrated, may undergo com- plete absorption, leaving the amni- otic cavity emf>ty. The vessels of the villi are under such circumstances completely obliterated, while nu- Tuerous blood -coagula are found between the cysts. If, however, the placenta be already formed at the beginning of the cystic degeneration, the villi having become atrophied upon that part of the chorion which does not participate in the development of the placenta, the neoplasni is confined, as a rule, to the latter, although cysts, evidently owing their origin to villi which have not undergone atrophy, sometimes occur upon the smooth surface of the chorion. Should the hydatidiform mole be of sufficient extent, under these circumstances, to destroy the foetus, the more or less disintegrated remains of the latter are found in the am.niotic cavity, which sometimes contains an excess of liquor amnii. If only a few of the placental lobes or single cotyledons be implicated, the growth of tlie foetus may not be disturbed. A healthy Fig 1« -SpenMieii tiom liMlatuliform mole, m the Wood JIuseum 300 THE PATHOLOGY OF PREGNANCY. fostus is occasionally developed side by side with a hydatid mole.* The hydatidiform mole is usually contained within the decidua. In an interesting case reported by Volkmann, however,f the degenerated villi had invaded the uterine blood-sinuses, and by pressure led to so extensive an atrophy and absorption of the uterine walls as to leave only a thin, transparent septum between the mole and the peritoneal covering of the organ. The cavity formed by this process of erosion in the uterine parenchyma was larger than the uterine cavity proper, and presented numerous intersecting trabecule resembling the columnar carneae of the cardiac ventricles. The destructive character of the cystic degeneration is attributed in such cases to some unknown mor- bid condition of the uterine walls, probably the result of malnutrition. Schroeder J refers to two similar cases, in one of which the cystic de- generation was attended by fatal peritonitis, and the other by rupture of the uterus, and death from hfemorrhage into the peritoneal cavity. II. Etiology. — Primiparffi are less frequently affected by the hyda- tidiform mole than multiparae, although the actual number of preg- nancies seems to exert a less marked predisposing influence than ad- vancing age. The cystic degeneration usually occurs during the first month of utero-gestation. According to Underbill,** the latter part of the third month is the limit within which the disease can originate. That the exciting cause of the hydatidiform mole may be a morbid ma- ternal condition, is rendered probable by the repeated recurrence of the disease in the same patient, by its coexistence with inflammatory de- cidual disease or with extensive uterine fibroids, and by the presence, in the majority of cases, of a cancerous or syphilitic dyscrasia on the part of the mother. If the origin of the degeneration be maternal, as it probably is in most instances, the degeneration of the chorion ante- dates and produces the death of the foetus. On the other hand, the fact that the morbid growth may owe its inception to fetal disease seems demonstrated by those cases in which, as has been already stated, a healthy foetus may be developed at the same moment with a hydatidi- form mole. This view is further supported by those cases in whidi death of the foetus is attended by so insignificant an amount of cho- rionic disease as to render its active causative agency in the death of the foetus highly improbable. Spiegelberg,|| however, is of the opinion that the hydatidiform mole does not result from death of the embryo, and that its cause is often to be sought in an abnormal development of the allantois. The establishment of the true pathological relations of the hydatidiform mole have led to the abandonment of the once preva- * Spiegelberg, Lehrbiich, p. 332. f Volkmann, Virchow's Archiv, Bel. xli. p. 528. I ScHROEDER, Lehrbuch, p. 429. * Underhill, The Hydatidiform Mole, Obstet. Gaz., January, 1879, p. 16. II Spiegelberg, Lehrbuch, p. 333. DISEASES OF THE OVUM. 301 lent opinion that the neoplasm might be developed independent of conception. The theory that a portion of retained placenta might become affected with the hydatidiform disease, has also been refuted by accumulated clinical evidence. III. Symptomatology. — A leading sign of the hydatidiform mole consists ill a failure of correspondence between the uterine enlarge- ment and the computed period of utero-gestation. The uterus is usually larger at any given stage of pregnancy than it naturally would be in the course of normal gestation, but may be decidedly smaller in those cases attended by early demise of the embryo. Lumbar and sacral pains are prominent and distressing in proportion to the rapid- ity of uterine development. The uterus imparts a peculiar doughy feeling to the palpating fingers, and in rare instances plainly jjercep- tible fluctuation. Individual parts of the foetus can not be distin- guished through the uterine walls. The lower segment of the uterus is remarkably tense. Ballottement yields negative results and fetal movements are absent, although they may be closely simulated by uter- ine contractions. The fetal cardiac sounds are diminished in inten- sity or are quite imperceptible. There is a discharge from the uterus, either constant or intermittent, consisting of disintegrated and unrupt- ured cysts, cystic fluid, and blood, which, although usually not excess- ive^ may be so much increased by uterine contractions induced by overdistention as to seriously impair the general strength, or even to induce death from exhaustion. Abortion is usually produced by the mole before the sixth month, but the expulsion of the neoplasm may be delayed until the normal period of parturition, or even until a later season. The haemorrhage and the characteristic discharge cease after the complete expulsion of the tumor, but retained portions of the same may give rise to pro- tracted bleeding. It is often impossible to distinguish the local signs produced by the expulsion of a large hydatidiform mass from those observed after normal delivery. Diagnosis. — In cases of limited cystic degeneration it is often im- possible to diagnosticate hydatidiform mole. The symptoms upon which, in well-marked cases, the diagnosis is to be based are rapid in- crease in the dimensions of the uterus, the presence of obscure fluctu- ation, the impossibility of obtaining the fetal heart-sounds or of grasp- ing any of the fetal members, negative result of ballottement, and uterine contractions, attended by the mucous or muco-sanguiuolent discharge containing the characteristic cysts. Prognosis.— The prognosis of hydatidiform mole is determined chiefly by the frequency and the violence of the attending haemor- rhages. It is not extremely unfavorable in the majority of cases. The existence of the peculiar form of cystic degeneration described as the interstitial, intraparietal, or eroding variety would, however, 302 THE PATHOLOGY OF PREGNANCY. iiuturally render the prognosis excee;lingly gruve. 'V\\v fatality of tliis class of cases results from their tendency to produce a rni)ture of the uterus complicated by intra])eritoneal ha'morrhage, peritonitis, or septicaemia. The life of the fcetus is almost invariably sacrificed. Treatment.— The treatment is restricted to measures calculated to control ha'morrhage and to promote the ex])ulsion of the diseased mass. Most writers recommend non-interference so long as the ute- rus remains passive. When contractions set in, the vagina should be tamponed, and ergot given in full and repeated doses, until the mole is expelled entire. The expectant plan is, however, not devoid of danger. In once case, where the patient sulfered from labor-pains for several hours before I saw her, the loss of blood was excessive. I succeeded in removing with the hand, through the patulous cervix, an enormous quantity of cysts, suthcient to lill a wooden ])ail. This was followed by good contraction of the uterus anil arrest of the hemorrhage, but the patient died two hours later from shock and anremia. Unless, therefore, the patient is so placed that professional assistance can be obtained at a moment's notice, the propriety of dilat- ing the cervix so soon as the diagnosis has been established may well be considered. Dilatation should be effected by the steel dilator, or by the dilators of Barnes or of Tarnier, or even by tents, if rare is taken to render them thoroughly aseptic. After expulsion, or after the manual removal of the hydatidiform (iysts, the uterus should be washed out with antiseptic fluids; or, in case of hiemorrhage, its inner surface should be swabbed with the per- chloride of iron. The irrigation of the uterine cavity with water, to which only sufficient perchloride of iron has been added to give it a wine-color, has often a powerful styptic effect. Underbill recom- mends the continued einployment of ergot after delivery, and, in cases of persistent ha;morrhage, the occasional introduction of the laminaria tent, and, if necessary, the employment of Thomas's dull- wire curette. Retention in Utero of the Dead Fcetus. In the normal uterus the causative conditions producing retention of the dead fcetus are not invariably identical. If the placenta remain adherent to the uterus after the demise ojf the foetus, the continued vitality and uninterrupted development of the placenta sufficiently explain the fetal retention. When, however, all connection between the placenta and the uterus has been severed, retention is probably i-eferable to the diminished irritability of those reflex nervous centers which control the expulsive uterine efforts. The duration of retention produced by adhesion of the placenta, in cases of single pregnancy, is protracted until such time as morbid placental processes impair the vitality of that organ and induce its separation.

Under these circumstances the retention is never jiro- longed beyond the normal period of gestation, and is thus distin- guished from those cases of retention owing their origin to so-called " missed labor." A mummified ftetus is flattened from compression. Its viscera are of soft consistency and of small dimensions. Its surface is shrunken. The peritoneal and pleural cavities contain a scanty and discolored fluid. The subcutaneous areolar tissue has disappeared, and the skin lies in direct contact with the muscles. The placenta, Avhich is dry, yellowish, and tough, is the seat of fatty degeneration, and contains the residue of old extravasations. Maceration. — The placenta of a macerated fretus (fcetus sanguino- lentus) is ana3mic, soft, and friable. The cord, in wliich the vessels are permeable, is cylindrical, smooth, spongy, and inelastic. Its coils have disappeared. It is club-shajied at the fetal extremity, and its color is brownish red. The amniotic fluid has a peculiarly repulsive, sweetish, and sickening odor, unlike that of putrefaction. The fluid is rendered turbid and of a greenish-yellow color by the admixture with it of sero-sanguinolent fluid, and of meconium. The membranes, which retain their normal consistence for a long time, finally become friable, swollen, and discolored. A foetus of only one to two months may be completely dissolved by the process of maceration. If the foetus be more mature, its general form and the outline of its organs are preserved, but granular degeneration and disintegration of their anatomical elements are everywhere present. The ejiidermis is first affected by the process of maceration. It is separated from the corium by the formation of vesicles similar to those of pemphigus, which con- tain either a reddish, sero-sanguinolent, or a clear serous fluid. The corium is infiltrated with the same fluid, and presents the appearance of brownish-red macerated parchment. The subcutaneous areolar and adipose tissues are reddish and redematous. The oedema is most ap- parent over the cranium, the abdomen, the feet, hands, and sternum. The entire body is flaccid, and assumes, under the influence of external pressure, curiously distorted shapes, being distended at some jioints and depressed or flattened at others. The cranial sutures are separated, the joints are disarticulated, and the periosteum has become detached from the long bones. The vessels are filled with dark, grumous blood. The serous cavities are distended with bloody serum. The brain is transformed into a grayish-red pulp. All the viscera are infiltrated and friable, the uterus and lungs preserving their normal consistence longer than the other organs. Pigment masses and fat-crystals are deposited in many organs. In rare instances the fetal organs become covered with a greasy substance composed of cholesterin and the margarates of soda, potassa, and lime. These saponified products are sometimes termed, collectively, advpocere. No trustworthy inferences can be DISEASES OF THE OVUM. 305 drawn from the appearance of macerated foetuses as to the cause of their decease, since the gross pathological conditions are identical under all circumstances.* Apparent variations are duo to the respect- ive periods of retention. The rapidity with which the process of maceration occurs is variable, and its extent is therefore no criterion of the time at which the fetal demise took place. Seventy-five per cent of macerated foetuses are expelled, according to Ruge,f before the thirty-first week, and transverse or breech-pres- entations occur in nearly one half of all the cases. The term missed labor was applied by Oldham to those cases in which, the uterine expulsive efforts having been ineffectually made at full term without other result than the escape of the waters, the uterine contractions finally subside, leaving the foetus in utero. The causes of missed labor usually cited are abnormal absence of uterine irritability, or of that residing in the reflex nervous centers, obstructed labor, and unusually close adhesions of the placenta. Note. — The occurrence of missed labor has recently been disputed by Muller (De la grossesse uterine prolongee indefiniment, Paris, 1878), who would refer all such cases to gestations occurring external to the uterine cavity. Certainly the criticisms of Miiller have greatly restricted the number of cases which formerly were unquestionably assigned to this category. In certain of them the foetus ap- pears secondarily to have made its way into the uterus through a communicating pas- sage, while in others the pregnancy may have been primarily of tubo-uterine or of mural origin. Still, Barnes has since related the history of a case (On the so-called " Missed Labor," Obst. Trans., vol. xxiii, p. 81) which affords strong affirmative evidence of the possibility of the prolonged retention of a foetus dying before the end of gestation was reached. The circumstances were briefly as follows : Mrs. B , aged thirty-nine, had borne three stillborn children. Five years later, m the month of October, the catamenia ceased. The movements of the child were felt between the third and fourth months. Between the eighth and ninth months there was a flow of blood from the vagina, which, however, ceased in a few days under the use of cold and styptics. At the end of three weeks the bleeding returned, but became lighter at the end of a week, and then gradually disappeared. At no time were there labor pains. At the end of January pieces of bone began to come away, and portions of bone were removed by the finger and forceps after partial dilatation of the cervix. In Febriiary, under chloroform, Dr. Barnes proceeded to empty the uterus. As the hand could not be got through the uterus. Dr. Barnes extracted the foetus with his craniotomy forceps. The foetus was a compressed mass, bones emerging in the surface, the fleshy part greasy, soft, and putrid. It presented the appearance of having reached the eighth or ninth month of gestation. The patient showed considerable shock after the operation, but rallied the next day, and eventu- ally recovered. Dr. Barnes was convinced, not only by examinations made during the extraction of the foetus, but by the subsequent daily introduction of the sound, that the cavity was continuous with the cervix, and that the dense wall felt in no respect differed from the characters of uterine wall. To his mind, even a post- mortem examination could hardly have made the case clearer. In the discussion which followed Dr. Barnes's report it was, however, suggested by Sir Spencer Wells and others that the case was really one of mural pregnancy. * RuGE, Zeit. f. Geb. u. Gyn., Bd. i, Deft 1, 1877, p. 58. t l^i^-^ P- "^O- 20 306 THE PATHOLOGY OF PREGNANCY. Dr. Stanley P. Warren, of Portland, Maine, sends me the following histotf, which seems conclusive : The patient menstruated last in January, 1884. In the following May she was attacked with general peritonitis. The 28th of October was computed as the probable terminus of gestation. At that time continuous cramp- like pains were felt by the patient. The presentation of the child was transverse. The cervix was not reached. For several days the pains recurred at night. By the second week in November it was ascertained that the child was dead. There was no further expulsive action. On December 30th, after vain attempts at dilata- tion of the cervix, Caesarean section was performed, and a female child, weighing eight and a half pounds, was removed from the uterine cavity. The patient died from shock twenty-eight hours after the operation. According to Kiichenmeister (Ueber Lithopadien, Arch. f. Gynaek., vol. xvii, p, 153), retention may result from obstruction due to hardening of the cervix, to car- cinoma, to fibroids in the lower segment, and where pregnancy takes place in the rudimentary cornu of a one-horned uterus. Retention due to obliteration of the cervical canal he rejects ; but I have witnessed three cases of complete occlusion of the vaginal vault, where it was necessary to dissect up a long passage to permit the birth of the child, and where, without artificial aid, either rupture of the uterus or retention of the child must have resulted. The pathological processes presenting themselves in case of long- continued retention and of missed labor vary with the entrance of air into or exclusion of air from the uterine cavity. If the atmosphere have free access to the uterus, the foetus undergoes putrefactive changes. The soft parts, having been liquefied, escape, leaving the osseous framework of the fretus in ntero. This may also be gradually and partially disintegrated, liquefied, and expelled, but its complete evacuation is not often effected by Nature's processes. If, however, the cervix be narrow or unyielding, the continuous pressure of some projecting and pointed bone may penetrate its tissues and force an exit through the vagina, rectum, or anterior abdominal wall. A similar irritation and penetration may induce supptirative metritis, and, event- ually, fatal peritonitis, or septicsemia. If the air be excluded from the uterus in cases of retention indefi- nitely prolonged, the foetus either becomes mummified, and, forming intimate connections with the uterus through the medium of inflam- matory products, remains in ntero ^v\i\\o\\i giving rise to any symp- toms, or it may produce by constant irritation suppurative metritis, with abscess formation and the escape of pus externally. Access hav- ing been thus afforded to the air, putrefaction and its consequences will then ensue. In rare cases of prolonged retention, the foetus becomes the seat of adipocerous changes.* Calcification of the foetus (lithopaedion forma- tion) occurs probably in cases of extra-uterine pregnancy only. The retention of the dead foetus is comparatively devoid of danger. Even if decomposition or putrefaction of the foetus occurs, it is common for the products of disintegration to be eventually eliminated, * Vide Case of Professor T. G. Thomas, N. Y. Med. Journal, vol. xxi, p. 163. THE PREMATURE EXPULSION OF THE OVUM. 397 without a fatal result, by natural efforts or by the intervention of ob- stetrical art. There is good evidence, however, that the dead fa^tus may, even if the access of air has been prevented, seriously impair the patient's health. Lately I have witnessed the development of albu- minuria subsequent to the death of the foetus, which disappeared upon the induction of premature labor.* Unless, therefore, labor sets in within two or three weeks after the death of the foetus, the induction of labor is indicated. The excep- tion to this rule would be in cases of twin pregnancy, where one foetus was still living. In prolonged retention, the elimination of pieces of bone should, as far as possible, be aided by the hand. If necessary to dilate the cervix, care should be taken lest spiculae of bone be pressed by the expanding body into the uterine tissues. Every precaution should be taken subsequently to render the uterine cavity aseptic. When the Csesarean section is performed and the uterine tissues are found extensively infiltrated, it has been suggested that the Porro operation may diminish the risks of infection. The efficacy of the measure would of course depend upon the freedom of the parametria from septic invasion. CHAPTER XVL THE PREMATURE EXPULSION OF THE OVUM.

Whex pregnancy is interrupted, during the first three months, by uterine contractions leading to the expulsion of the ovum, the term abortion is used ; in the fourth, fifth, sixth, and seventh months — i. e., from the formation of the placenta to the time the child becomes viable — it is proper to speak of the accident as immature delivery, or miscarriage ; and, finally, a confinement occurring from the twenty- eighth week, the earliest period of viability, to the thirty-eighth week, when the fcetus possesses every indication of maturity, is distinguished as premature delivery. This purely artificial division is justified by praerieal differences in the symptomatology and treatment of the groups thus separately designated. * Vide also Barker, On Puerperal Disease, p. 402. KEMtiJR, Retention «• Utero of the Dead Fcetus. Trans. Iiid. State Med. Soc, 1875. 308 THE PATHOLOGY OF PREGNANCY Causes which lead to the Peematuke Interruption of Pregnancy. The underlying causes of abortion, miscarriage, and premature delivery are the same. Causes of abortion are rarely of sudden occur- rence. Usually the way is prepared, either by changes taking place in the ovum, or by certain pathological conditions affecting the mother. In either of these ways a disposition to abortion is produced. When once, as the result of morbid changes, the attachment of the ovum to the uterus has been rendered insecure, causes usually inopera- tive suffice to determine uterine contractions and the time at which the expulsion takes place. The Disposition to Abortion.— The disposition may be due prima- rily to any disease of the chorion, of which we have an example in syphilitic degeneration of the villi. In most cases, however, death of the foetus precedes and leads to disease of the chorion. The causes of abortion resolve themselves, therefore, in large measure, into the causes which produce death of the foetus. The death of the foetus may be due to direct violence, as kicks and blows upon the abdominal walls ; to diseases of the fetal appendages (cord, amnion, chorion, placenta) ; to diseases of the decidua, especially those which give rise to haemorrhage (before the complete formation of the placenta, the separation of the decidua from the uterus inter- feres with the nutritive supplies which go to the foetus) ; to febrile affections, in which death results either from the high temperature, from associated diseased conditions of the decidua, or, as in certain acute infectious diseases, to the direct transfer of the poison from the mother to the foetus ; and, finally, to excessive anaemia. Anaemia de- veloped by pregnancy rarely affects the child. In acute anaemia from profuse hajmorrhage, the child may die from asphyxia. In times of famine great numbers of women abort. The disposition to abort ob- served in corpulent women is probably due to the fact that the blood is insufficient in quantity and quality to supply the wants of the growing child. The death of the foetus is followed by the expulsion of the ovum, not usually at once, but after a longer or shorter period of time. Be- fore the third month, in such cases of delay, the embryo, which con- sists of hardly more than a heap of cells, may become macerated, and absorption may take jjlace after the death of the embryo. Except in cases of hydramnion, partial collapse of the ovum ensues. As soon as the foetus dies, the circulation which passes from the foetus to the cho- rion and placenta is suspended. The villi then become obliterated, and undergo fatty degeneration. The decidua is affected by the same process. With the diminution in the volume of the ovum, contrac- tions begin. The villi, loosened in their attachments to the decidua, THE PREMATURE EXPULSION OF THE OVUM. 309 are drawn out, and the decidual vessels, exposed and subjected to in- creased pressure, rupture, and haemorrhage results. The uterine con- tractions are awakened and exercise an expulsive force upon the ovum, which in its descent expands the cervix from above downward, and passes finally into the vagina. In the first three months the ovum is not infrequently expelled with membranes unruptured. From the end of the third month onward such an occurrence is rare, though I have seen an instance which happened in the sixth month. In the early months the expulsion of an intact ovum is associated with in- considerable haemorrhage. When the membranes give way, the em- bryo and the fluid contents of the amnion escape first. With the removal of the compression exercised by the ovum upon the inner surface of the uterine walls, haemorrhage occurs, which continues, as a rule, nntil the complete expulsion or removal of the membranes and placenta. Aside from the death of the foetus, with consecutive changes in the chorion and decidua, and diseases of the fetal appendages leading to death of the foetus, the predisposition to abortion may be the result of primary defects or changes in the decidua alone. Of these changes w^e recognize : 1. Atrophy of the Uterine Mucous Membrane. — The insufficient development of the mucous membrane exercises an injurious influence uj^on the development of the ovum in cases only in which the serotina and the reflexa are in- volved. An abnormally small and undeveloped serotinal sur- face may give rise to a small pla- centa, or the serotinal attach- ment may be of such limited ex- tent that the mere weight of the ovum drags it downward and converts it into a long, narrow ,. . 1, ,1 !_■ ,^ Fig. 135.— Ovum, with imperfectly developed pedicle. At other times, the re- decidua ; outer surface of vera. (Duncan.) flexa may be but partially devel- oped, or may fail altogether, and then the ovum, covered only by the chorion, hangs by a pediculated attachment to the serotina. In both these cases the uterine contractions, instead of at once effecting the expulsion of the ovum, may force the ovum into the cervix, where it may remain for a time, nourished by the long pedicle, but arrested in its further descent by a contracted os externum. To these cases the term cervical pregnancy has been applied. The cervix, according to the month of pregnancy, is more or less spherically dis- tended, and the corpus uteri above contracts down to nearly normal dimensions. As the cause of this condition lies chiefly in rigidity of 310 THE PATHOLOGY OF PREGNANCY. the OS externum, it occurs most frequently in primipara. Even with a patulous os, though rarely, a cervical pregnancy may be produced by the resistance and firmness of the pedicle attaching the ovum to the uterus.* 2. Hypertroi)liy of the Mucous Membrane.— Thickening of the mu- . cous membrane is the result of endometritis, and may lead to abortion in either of the following ways: The several forms of endometritis may give rise to affections of the placenta, and thus prove fatal to the foetus, or the thinned, dilated vessels of the diseased decidua may rupture, and produce sanguineous effusions between the membranes. The frequency of abortion in displacements of the uterus is prin- cipally dependent upon associated endometritis. In anteflexion of the uterus, sterility is common, but endometritis and abortion are rare. In retroflexion, on the contrary, while there is slight obstacle to con- ception, the congestion of the uterine walls and the altered conditions of the uterine mucous membrane render abortion a frequent occur- rence. Eigidity of the uterine walls, which interferes Avith their due ex- pansion, may lead to premature uterine contractions. In "this way an imbedded flbroid or carcinoma may ultimately become sources of abor- tion. Expansion of the uterus may likewise be hindered by old peri- toneal adhesions or pelvic cellulitis. • Finally, there remains a class of women in whose cases it is impos- sible to detect either disease of the ovum or of the genital organs, yet in whom abortion occurs, dependent, so far as our present knowledge •goes, upon certain personal conditions of nerve irritability. Physical and psychical sources of excitement which would be of small moment in some women, in them suffice to interrupt pregnancy. Immediate Causes of Abortion. — Changes in the ovum other than rupture and escape of the amniotic fluid rarely lead at once and di- rectly to abortion. The proximate causes which induce contractions and the throwing off of the ovum reside for the most part in the ma- ternal system. They consist of : 1. Hypercemia of the Gravid Uterus. — When the predisposing causes have operated to weaken the attachments of the ovum to the decidua, anything which determines the blood-currents to the uterus is liable to produce extravasations of blood around the ovum, and awaken uterine contractions. Because of this fact, we surround patients pre- disposed to abort with every precaution during the periodic menstrual congestion that not even pregnancy altogether suspends. Fevers, in- flammatory affections of the genital organs, excesses in coitus, hot foot-baths, valvular heart lesions, obstructions to the circulation of the lungs and liver, may each lead to rupture of the decidual vessels. * W. ScHULEix, Ueber cervicale Schwangerschaft, Ztschr. f. Geburtsh. und Gy- naek., Bd. iii, H. 2, p. 408. THE PREMATURE EXPULSION OF THE OVUM. 3H More frequently rupture follows jars to the body from vomiting, cough- ing, and straining, from railroad journeys, from violent exercise, from falls, and the like. The importance of separating the predisposing from the immediate causes of abortion is shown by the impunity with which often i)er- fectly healthy women, with no abnormal conditions of the generative organs, set all the usual restraints at defiance with the intent to inter- rupt an undesired pregnancy. M. Brillaud Laujardiere relates the case of a peasant who took his wife, while e)iceinte, behind him on horseback, and started off with her at full gallop with the view of caus- ing her to miscarry. Having thus thoroughly shaken her, he dropped her suddenly to the ground Avithout slackening his speed. This brutal manoeuvre he repeated twice without the least success.* On the other hand, women eager for offspring, after an abortion, sometimes lay undue stress upon slight imprudences, and make them the sources of morbid self-reproaches, which it becomes one of the functions of the physician to allay. 2. Uterine Contractions jiroduced hy Influences tohich act directly through the Nerves. — Of this we have examples in the contractions awakened by frictions of the uterus through the abdominal walls, in the reflex contractions j^roduced by stimuli applied to the breasts, and in those excited by strong mental emotions. Symptoms. — As the detachment and expulsion of the ovum can not possibly take place without rupture of the decidual or placental ves- sels, haemorrhage becomes the constant and necessary result of every abortion. In the first two months the haemorrhage resembles that of a profuse menstruation. Pain is present, in part due to uterine con- gestion, in part to the expulsion of blood-clots through the imperfectly expanded cervix. The latter pains resemble those of obstructive dys- menorrhoea. These symptoms last from four to five days. As the ovum passes away unnoticed, enveloped in the clots, or piecemeal with the decidua, women are apt to regard these early abortions as the normal recurrence of a retarded menstrual jieriod. After the second month prodromal symptoms are rarely wanting. Among these may be mentioned fullness and weight in the pelvis, sa- cral pains, frequent micturition, periodic labor-like pains, and a mu- cous or watery discharge. These, followed by haemorrhage, indicate a threatened abortion. The hwmorrhago. if slight, may cease, and the pregnancy go on undisturbed. Usually, however, the haemorrhage increases in amount, or after a brief cessation recurs. Contractions set in, which become more and more pronounced, until finally the ovum is expelled. In a typical case of abortion, in which the ovum is thrown off entire, uterine retraction and haemorrhage unite to effect the progress- * T. GrALLARD, De ravortement an i)oint de vue iiuHlieo-legal, Paris, p. 24. 312 THE PATHOLOGY OF PRE&NAXCY. ive separation from below upward of the decidiia from the uterine walls. The ovum then, covered by the refiexa and the detached de- cidua, is gradually pressed downward, and dilates first the os internum, next the cervix, and finally the os externum. The ovum passes into the vagina, covered by the decidua vera, or drags the inverted decidua after it. The emptied uterus then retracts down, and the hemorrhage ceases. The aborted ovum is surrounded with coagulated blood. In the first three months, when the death of the embryo has preceded by a little time the completion of the abortion, every vestige of the em- bryo may be found to have disappeared. Sometimes, in the third month, a small placenta with shrunken umbilical vessels may now and then be met with. When the extravasation of blood upon the uterine surface of the vera is considerable in amount, the vera is sometimes broken through, and the blood effused between the vera and reflexa. Extravasation may likewise take place between the reflexa and chorion, either in consequence of the rupture of the reflexa, or from a haemorrhage start- ing from the placenta, which finds its way along the Outer surface of the chorion, and dissects away the reflexa. The pressure upon the ovum, unless it has joreviously undergone collapse as a result of the death of the embryo, leads to rupture and escape of the amniotic fluid. The retained fetal and maternal membranes, with the intervening lay- ers of coagulated blood, form a mass termed a mole. When the blood coagula are fresh, the mass is termed the mola mngiiinea (blood-mole), and when of older date the mola carnosa (flesliy mole). The cavity, which is lined by the amnion, has usually an irregular surface. It is very exceptional for extravasations to break through both chorion and amnion, and thus form clots in tlie amniotic cavity itself. Moles sel- dom exceed an orange in size, and usually are expelled between the third and fifth month. In cases where abnormal adhesions attach the vera and serotina to the walls of the uterus, retained portions of the maternal membranes may remain after the ovum is expelled. In another class — and this is the rule after the third month — the fetal membranes rupture, and the embryo escapes with the liquor amnii. While ordinarily the retained portions quickly follow the discharge of the ovum or embryo, it fre- quently happens that the uterus retracts upon its contents, the cervix closes, and a period of repose follows. There is then produced what is commonly known as an incomplete abortion. Incomplete Abortion. — The various contingencies arising from these cases of incomplete abortion are thus truthfully depicted by Spiegel- berg : * 1. Most frequently haemorrhage continues at intervals, spontaneous elimination gradually taking place as, through retrograde changes, por- * Spiegelberg, Lehrbuch der Geburtshulfe, Jahr., 1877, p, 377. TUE PREMATURE EXPUI.SION OP THE OVUM. 513 tions of tlie retained membranes become successively loosened in their attachments to the uterus. 2. In exceptional cases the hemorrhage ceases for a time entirely. For days, weeks, and even months, the woman appears quite well. Then suddenly strong contractions, accompanied by profuse hfemor- rhage, usher in the elimination of the fetal dependencies. In a case of my own, three months elapsed from the occurrence of the first haemorrhage, which took place toward tlie end of the third month, and was quite insignificant in amount, before the abortioii was com- pleted. Meantime, as there were progressive abdominal enlargement, supposed quickening, and milk in the breasts, the threatened abortion was believed to have been arrested. Total retention, with a long in- terval of repose, is thought to be due to complete adherence of the l^lacenta, which continues to receive nutrient supplies from the uterus. Spiegelberg believes that a menstrual period is the usual time at which the discharge of the retained membranes takes place. 3. Of more frequent occurrence than the foregoing is the putrid decomposition of the retained portions. It occurs chiefly in cases where there is more or less complete loss of organic connection between the placenta and the uterus. Decomposition in the non-adherent por- tions is produced by the introduction of air during the escape of the embryo, or through the subsequent passage of the finger into the ute- rus, or, where portions of the ovum hang down into the vagina, by absorption of septic matter from the vagina upward into the uterus. As a result of putrid decomposition, the woman is exposed to septicae- mia, and infection of thrombi at the placental site. Fatal results are, however, rare, as decomposition is usually a late occurrence, setting in, as a rule, only after protective granulations have formed upon the uterine miicous membrane, and after the complete closure of the uter- ine sinuses. Continuous fever, with intercurrent attacks of ha?mor- rhage, is, however, set up, but passes away finally with the gradual dis- charge of the decomposed particles, while the threatening symptoms subside. Still, now and then septic processes lead to an unfavorable termination. Local perimetritic inflammation is a common event. 4. Where there is a certain degree of relaxation with enlargement of the uterine cavity, the fibrin of the extravasated blood may become deposited about any uneven surface within the uterus and give rise to a polypus-shaped body, suggestive in its mode of develojunent of the stalactite formations in calcareous caverns.* These so-called iiln-inous polypi generally develop around the dehri>i of an abortion, such as retained bits of decidua, placental remains, and portions of the fetal membranes. In some cases, likewise, thrombi projecting from tJie placental site become the base of a loose fibrinous attachment. Pla- * Frankel, Beitrag zur Lehre von fibriniisen Polypen, Arch. f. Gynaek.. Pd. ii, p. 76. 314 THE PATHOLOGY OF PREGNANCY. cental polypi give rise ultimately to bearing-do wu pains and intercur- rent hgemorrhages. They may even decompose, and endanger life by septic absorption. The retrograde changes that take place in a uterus after an abor- tion correspond to those which occur in deliveries at full term. Where Fig. 136. — Uterus, with basis of a fibrinous polypus after an alxiriioii. (Frankel.) a suitable plan of treatment is not adopted, or where the importance of care in the after-management is not adequately appreciated, sub- involution is apt to follow. Of all sources of uterine disease, none takes precedence of a mismanaged abortion. Diagnosis. — The diagnosis is based upon the presence of pain, hgemorrhage, dilatation of the cervix, and the descent of the ovum. When the ovum can be felt through the patulous os the demonstration is of course complete. A soft polypus may, however, present a decep- tive resemblance to a small ovum. In all eases of pregnancy the exist' THE PREMATURE EXPULSION OB^ THE OVUM. ;J15 ence of hfemorrhage alone, even when disassociated from other symp- toms, renders the probabilities of abortion sufficiently great to call for the exercise of every precaution. It is not easy to recognize pregnancy in the early months, but in doubtful cases the cessation of the menses should be regarded as presumptive evidence of its existence. The diagnosis of these pathological changes in the ovum and de- cidufe which pave the way for abortion can not be made out with certainty from mere subjective symptoms. Such changes may be regarded as probable Avhen the size of the uterus does not correspond to the supposed period of gestation. Thus, if the uterus at the lifth month was no larger than is usual at the third month, the death of the embryo with arrest in the development of the ovum would be naturally inferred. When the physician is summoned to a case of haemorrhage occur- ring during pregnancy, he should at once examine the clots, where they have been preserved, for traces of the ovum. The clots should be broken up under water, and a careful examination made for floating fringes of villi. The ovum, when expelled entire, is usually enveloped in layers of coagulated blood, so that without tliorough search it would easily pass unnoticed. If the coagula have been thrown away, and the physician finds upon his arrival the cervix closed, so that he can not 2)ass his finger into the uterus to explore its cavity, it may be im- possible at once to determine whether the abortion has taken place wholly or in part, or whether the entire ovum still remains in utero. The subsidence of all symptoms points, as a rule, to a complete emp- tying of the uterus, or to an arrest of the abortion, though in some cases it precedes mole-formation. A renewal of the haemorrhage and the absence of normal involution indicate the continuance of the ovum in the uterus, or an incomplete abortion. Prognosis. — The prognosis takes cognizance, of course, of the results to the mother only. In the first place, it may be laid down in the way of broad general statement, that all cases of spontaneous abortion (i. e., excluding criminal cases) not complicated with other morbid condi- tions are, under suitable medical guidance, devoid of danger. But, in the second place, it must be borne in mind that the statement is only true with the reservations that limit it, for in point of fact the actual number of deaths from abortion is by no means inconsiderable. Thus, the deaths from this cause reported to the Bureau of Vital Sta- tistics of New York City between the years 18G7 and 1875, inclusive, were one hundred and ninety-seven* — a number which falls short, in all probability, of the truth, by reason of the many circumstances which precisely in this condition tempt to concealment. The total number of deaths during the same period from metiia was, according to the * LusK, Nature, Origin, and Piovention of Puerjieral Fever, Transactions of the International Medical Congress, Philadelphia, p. 8oO. 316 THE PATHOLOGY OF PREGNANCY. reports rendered, 1,947. Hegar * reckons one ubortiou to every eight to ten full-time deliveries. If this proportion be correct, it would seem to show that the mortality from abortion is hardly second to that from puerperal fever itself. Death, as a consequence of criminal abortion, is especially.frequent. M. Tardieu found that in one hundred and sixteen such cases of which he was able to ascertain the termination, sixty women died.f But even in spontaneous cases death may take place from hemorrhage, from sep- ticemia, or from peritonitis. In many instances the fatal termination is fairly attributable to the ignorance, the imprudence, or the willful- ness of the patient. How far the dangers of abortion may be neutral- ized by proper medical assistance is best shown by the statistics of large hospitals. Thus, I gather from the reports issued by Dr. John- ston during his seven years' mastership of the Kotuuda Hospital, in. Dublin, that in two hundred and thirty-four cases of abortion treated in that institution there was but one death, and that not from puer- peral trouble, but from mitral disease of the heart. Bellevue Hospital is the receptacle annually of a tolerably large number of women suffer- ing from incomplete abortions, many of whom enter the hospital in a very unpromising condition from either excessive hemorrhage or septic decomposition of the retained portions of the ovum. Yet, of the many patients whose histories I find in the record-books of the hospital since it has been customary to clear out the uterus in every case of incom- plete abortion, all have recovered. Treatment. — The treatment is divided into — 1. Prophylaxis in cases of habitual abortion ; 2. Arrest of threatened abortion ; 3. Means adopted to avert the dangers of a progressing abortion. Prophylaxis. — Prophylaxis considers the cause which underlies, in each case, the disposition to repeated abortion. One of the principal of these causes is syphilis in one or both parents. It is just in these cases that the triumph of the mercurial treatment has been most com- plete. The treatment should be addressed to the parent affected, or both parents should be subjected to the same treatment. Among local conditions amenable to treatment may be mentioned endometritis, displacements, and perimetritic inflammations. In re- troflexions and retroversions, the best results often follow the rephu^e- ment of the uterus and the employment of a suitable pessary. Xo harm results from the use of pessaries during pregnancy. They should, however, be watched, on account of possible vaginal irritation. After the completion of the third month they should be removed, as the uterus then remains in place without artificial assistance. When back- ward displacement of the uterus follows abortion, reposition aids nor- * Hegar, Beitrage zur Pathologie des Eies, Monatsschr. f. Geburtsk., Bd. xxi (supplement), p. 34. t T. Gallard, De I'avortement au point de vue medico-legal, Paris, 1878, p. 45. THE PREMATURE EXPULSION OP THE OVUM. 317 mal involution. When endometritis is secondary to extensive cervical laceration the Emmet operation is indicated. In carcinoma and large fibroids treatment is powerless. Where, in such cases, sterility does not exist, happily for the mother, the associated morbid conditions of the uterine mucous membrane and the rigidity of the uteri ue walls lead commonly to the death of the ovum and jiremature uterine contractions. Where a small fibroid in the posterior uterine walls leads to sterility by the production of retro- flexion, a pessary may, after replacement, at times be used with benefit. One abortion sometimes follows another in rapid succession in newly married women. While the first abortion may have been due to some accidental cause, the sequence is often kept up by a morbid condition of the endometrium, generated by the shortness of the inter- val between the pregnancies, which does not allow time for the detach- ment of the decidua and the restoration of the membrane to a normal condition. In such cases, curetting is often of service, and a six weeks' abstention from sexual intercourse may be usefully enjoined. In certain diseases of the placenta, in which the respiratory func- tion of the organ had suffered any marked diminution. Sir J. Y. Simpson believed he had succeeded in averting the death of the foetus by increasing the oxygen in the blood of the mother, through the ad- ministration of chlorate of potash.* Chlorate of potash may be given in doses of twenty grains, three times daily, for weeks at a time, with- out injury to the mother. Though it has not always rendered me the hoped-for service, the experience of other physicians, among whom I may mention Dr. Fordyce Barker, appears favorable to its employ- ment. In the class of cases in which abortion results neither from disease of the ovum nor of the uterus, but seems dependent upon some pe- culiar condition of nerve-irritability, the patient should not oidy avoid every known means of awakening uterine contractions, but should exercise the utmost caution at the recurrence of the menstrual epochs. Especially at the terminations of the second and third months a week's quiet in bed should be insisted upon. Dr. E. J. Jenks f recommends the viburnum prunifolium in cases where the habit of aborting has been formed. He writes : " My mode of prescribing the viburnum is to have the patient take from a half-teaspoonful to a teaspoonful of the fluid extract four times a day, beginning at least two days before the menstrual date, and continuing it not only during the usual period of the menstrual flow, but two days longer than that discharge continues when the woman is not pregnant." From the fourth month onward, the danger of the occurrence of abortion rapidly diminishes. * Sir J. Y. Simpson, Obstetric Memoirs, edited by Priestley and Storer, Edin- burgh, 1865, vol. i, p. 460. f Jenks, Viburnum Prunifolium, Trans, of the Am. Gyna?coI. Soc, vol. i, p. 130. 318 THE PATHOLOGY OF PREGNANCY. The Arrest of a Threatened Abortion.— Arrest may be accomplished in cases in which the death of the ovum has not taken place, and where the haemorrhage arises from a slight detachment only of the decidua or placenta. In every case of threatened abortion occurring in the early months, a careful examination should be instituted to ascertain whether retro- flexion or retroversion exists. In the genu-pectoral position, replace- ment is easy. If the fundus is slowly raised by two fingers introduced into the vagina, so soon as the horizontal line is reached the uterus falls forward of. its own weight. Replacement alone, in certain cases, suffices to relieve the congestion which furnishes the immediate cause of the abortion. In a paper read by Dr. J. A. Dol^ris before the Obstetrical Section of the Ninth International Medical Congress, entitled The Treatment and Restoration of the Cervix Uteri during Pregnancy, that distinguished French accoucheur advocated the performance of trachelorrhaphy in certain cases of cervical lac- eration during pregnancy, as a means of averting threatened abortion. The subject is of such importance, that I take this opportunity of relating the following personal experience : Mrs. X. was married at the age of twenty. Ten months later she gave birth to a vigorous child, which weighed ten pounds. The cervix was torn on the left side to the vaginal junction. Three months after the birth of the first child she became again pregnant. Very early in pregnancy she had repeated attacks of hfemorrhage, with continuous sero-sanguinolent discharges. At the end of six months she gave birth to a child which lived for a few hours. The placenta was firmly adherent and was to a great extent impaired in its functions by the presence of white infarctions. In childbed the uterus became displaced backward, so that its reposition was necessary. Owing to continued sanguinolent discharges, at the end of five weeks the uterine cavity was curetted. This was followed witliin four weeks by the symptoms of a new pregnancy. Again the i)atient had hemorrhages, sero-sanguinolent discharges, and intermittent ])ains, and was confined almost constantly to her bed. As she was earnestly desirous of carrying her child to term, she eagerly accepted, when gestation was three months advanced, my proposition to perfonn Emmet's operation. The result was immediate. The pains, the discharges, the haemorrhages ceased as if by magic. The patient felt herself perfectly well, and at full term gave birth to a girl weighing seven pounds. Pain in the back during pregnancy should be regarded by women as a warning for them to temporarily abstain from their ordinary avo- cations. With ever so slight a htemorrhage, they should at once be made to lie down and keep perfectly still. Simple turning in bed may start up fresh bleeding. Restlessness and mental excitement should be allayed by opiates in full doses. Ice to the vulva, cold cloths to the abdomen, and the internal administration of haemostatics, are not indi- cated. The fluid extract of viburnum prunifolium is recommended by Dr. Jenks, in teaspoonful ,doses every two or three hours, as long THE PREMATURE EXPULSION OP THE OVUM. 319 as its use seems to be demanded.* Tlie author's somewhat limited experience has appeared favorable to the claims put forth for the viburnum as a uterine sedative. Where the foregoing measures prove successful, it is a safe rule to keep the patient in bed for a week after the final disappearance of the threatening symptons. In cases of ascertained death of the foetus, and in those of inevi- table abortion, all measures calculated to retard the emptying of the uterus should be at once abandoned. In the first four months there are no unequivocal signs of the death of the fcBtus. From the middle of pregnancy onward death may be assumed, if, after repeated examinations, the absence of the fetal heart- sounds and fetal movements is confirmed. The signs of inevitable abortion are profuse haemorrhage, clots dis- charged from the uterus, dilatation of the cervix from the descent of the ovum, and a patulous condition of the os externum. Other symp- toms consist of persistent uterine contractions, escape of the amniotic fluid, and the presence of the embryo or of portions of the ovum in the discharged clots. How far the ordinary signs may in given cases prove delusive, is shown by a remarkable one reported by Scanzoni, of a woman who was seized with profuse metrorrhagia in the third month of pregnancy. Great numbers of clots were discharged. As all hopes of saving the ovum were abandoned, ergot was used in large doses, a tampon was placed in the vagina for thirty-six hours, a sound was em- ployed to explore the uterus, and finally, as the bleeding continued for three weeks, an intra-uterine injection of a weak solution of perchloride of iron was resorted to. Eight weeks later the patient quickened, and presented the distinctive evidences of a pregnancy advanced to the sixth month. f The Treatment of Inevitable Abortion. In the treatment of inevitable abortion it is proper to distinguish between cases of abortion proper and those of miscarriage. To avoid, however, needless repetitions, it is only points of distinctive difference to which, at the close, attention will be directed. The management of premature deliveries differs in no respect from that of confinement at term. In the first two months little treatment besides rest in bed for a few days is ordinarily required. In the exceptional cases the treat- ment does not differ from that m the haemorrhages of the non-preg- nant uterus. In the third month we distinguish — 1. Cases in wliich the ovum is thrown off entire; 2. Cases in which the sac ruptures and the em- bryo escapes with the discharged fluid. * Jenks, loc. cit., p. 130. f Scanzoni, Lelirbuch der Geburtshillfe, Wiori, 1867, p. 83. 320 THE PATHOLOGY OF PREGNANCY. 1. When in the third month the ovum is thrown ofE without rupt- ure of the fetal membranes, the hsemorrhage rarely assumes dangerous proportions. The uterine contractions press the ovum into the cervix, which dilates, and, in primiparse, becomes somewhat elongated. As the ovum descends, the body of the partially emptied uterus retracts. The eliused blood coagulates in thin layers between the ovum and the uter- ine walls. The ovum forms a tampon, which fills the cervix and re- strains the hgemorrhage. No active treatment is, therefore, demanded. A carbolized vaginal douche may be used twice a day as a measure of cleanliness. All attempts to disengage the ovum with the finger should be avoided, as endangering its integrity. The vaginal tampon is unnecessary. It should only be used as a safeguard, where patients live at a distance from medical assistance and can only be visited at long intervals. As it is never certain that the rupture of the ovum may not take place during the course of its expulsion, the tampon may in such cases be employed in anticipation of a possible increase of hemorrhage from sudden collapse of the membranes. In multiparas the ovum seldom remains long in the cervix. In primiparae, on the other hand, the tardy dilatation of the os externum may lead to a retention of the ovum in the cervix, lasting for days. As this condition is extremely painful, it is allowable to dilate the os externum with the index-finger, with Goodell's steel dilator, or even by incisions through the ring of circular fibers which furnish the cause of delay. Small portions of the decidua vera sometimes remain attached to the uterine walls after abortion. They commonly do no harm, but are discharged with the lochial secretion. The amount of the latter after abortion is not usually large where the ovum has been expelled entire. It is for the most part watery, and does not usually last longer than a week. A protracted bloody discharge may, however, be main- tained by decidual retention. This is most apt to result from meddle- some interference with the intact ovum, or in criminal abortion when the expulsion of the ovum has not been preceded by gradual changes in the decidual uterine attachments. The decidua can be safely and easily removed by means of the dull-wire currette. Peliminary dilata- tion of the cervix is rarely called for. As an after precaution against infection, cotton soaked in compound tincture of iodine should be passed into the uterine cavity by means of the ordinary applicator. 2. When the sac ruptures and the liquor amnii escapes, the re- moval of the pressure exerted upon the uterine wall by the intact ovum is followed by profuse haemorrhage from the utero-placental vessels. The diagnosis of rupture may be made either from finding the embryo in the clots, or, in the case of a dilated cervical canal, by the direct examination of the uterine cavity. Although after rupture THE PREMATURE EXPULSION OF THE OVUM. 321 portions of the ovum may still be felt, we miss the smooth surface of the fluctuating amniotic sac. When the embryo can not be found, and the cervix is closed, profuse haemorrhage alone would render the occurrence of rupture extremely probable. The principles of treatment in these cases are very simple. The indications are, to check the hemorrhage and to empty the uterus. As to the best methods of attaining these results, opinions widely differ. When cases are treated with rest in bed, the internal administration of ergot, and cold cloths applied to the abdomen and vulva, the loss of blood is usually considerable, but the most of them terminate favor- ably. In some, however, the hasmorrhage may prove so severe as even to threaten life. Now, it is in every way desirable, for the future wel- fare of the patient, to restrain the haemorrhage within the narrowest limits. The most effectual means of arresting the hemorrhage is to clean out the uterus. If, therefore, the physician at the time of his visit finds the cervix sufficiently dilated to allow him to introduce his finger into the uterus, he should not hesitate at once to remove the retained portions of ovum. If the vagina is thoroughly disinfected and the hands are surgically clean, the operation is absolutely devoid of danger. It does not require any considerable amount of technical skill, while the immediate results are in the highest degree satisfactory. The patient should be placed crosswise in bed, with the hips drawn well over the edge. The legs should be flexed and the thighs held, where assistants can be obtained, at right angles to the body, to secure the greatest degree of relaxation to the perineum and abdominal walls. The right index-finger should then be passed into the vagina and through the cervical canal, while the left hand, placed upon the abdo- men, gradually presses the uterus down into the pelvic cavity so as to bring it within reach of the examining finger.* This portion of the act should be performed slowly, while every effort is made to divert the attention of the patient. Hasty manipulations invariably excite in the most willing of patients the full resistance of the abdominal walls. When the point of the finger reaches the os internum, it is sometimes necessary to pause for a minute or two to await a sufficient degree of dilatation to allow the finger to pass beyond the insertion of the nail. When the right finger is used, it should be made to pass upward with its dorsal surface along the left side of the uterus to the opening of the Fallopian tube, thence across the fundus to the right side. As the tip of the finger passes down upon the right side, it presses the detached * Professor A. R. Simpson (Transactions of tlie Edinburgh Obstetrical Society, vol. iv, p. 237) recommends drawing down the uterus by means of volsellum- forceps attached to the anterior lip of the cervix. I have once seen extreme h.-emor. rhage follow this manoeuvre (seventh month of pregnancy), and now feel some hesitation about its employment, at least in the later months. 21 322 THE PATHOLOGY OF PREGNANCY. ovum before it toward the os internum. By the time the finger has thus made the circuit of the uterus, the ovum is pressed into the cervical canal, and thence passes easily into the vagina. With the left finger, the movement is exactly the reverse. The finger passes first, with its dorsal surface directed to the right side, from the right Fallopian tube across the fundus, and downward along the left side of the ut«rus. The only resistance the finger meets is at the placental insertion, where a certain amount of manipulation is required to complete the detach- ment.* Where the uterus can not be pressed down within reach of the index-finger by force exerted above the symphysis pubis, it is permis- sible to introduce the hand into the vagina ; but, in such a case, the fingers are apt to become cramped, and freedom of manipulation is impaired. A better means of overcoming the difficulty consists in the administration of an anaesthetic In cases of extreme anaemia chloroform should be discarded as too dangerous. Ether, hoAvever, has often seemed to me, on the contrary, to possess a stimulating action, and its use to be followed by increase in the volume and force of the pulse. The relaxation produced by the anaesthetic makes it easy to depress the uterus down to the pelvic fioor, whore it can be reached with comparative ease. After the removal of the ovum, the cavity of the uterus should be washed out with a stream of tepid carbolized water, in order to bring away any small detached portions of the ovum and decidua. In the manual extraction of the ovum, deliberation and perseverance are the main elements of success. If, when the patient is first seen by the physician, the cervix is not sufficiently dilated to allow the finger to pass without force, the vagi- nal tampon should be employed. The tampon restrains the haemor- rhage, stimulates the uterus to conti-action, and allows time for the employment of measures to rally a patient exhausted by profuse losses of blood. The material of which it is made is a matter of indifference, provided only it fills the vagina to its utmost capacity. In cases of urgent need, a soft towel, handkerchiefs, strips of cotton cloth, damp- ened cotton- wool, and the like, may be seized upon to meet a temporary emergency. The time-honored sponge, on account of its porosity, is least deserving of favor. When, however, the physician proposes to leave his patient for a number of hours, the mere hasty filling of the vagina through the vulva will not suffice. On the contrary, the high- est degree of safety can only be secured by the closest observance of the rules of art. The first essential of a good tampon is that it be carefully packed around the cervix uteri, and fill out the more dilatable upper portion of the vagina. This can be accomplished only by the aid of a specu- lum. The method I usually employ is one the credit of which, so far * Vide HiJTER, Compendium der geburtshulflichen Operationen, p. 22. THE PREMATURE EXPULSION OF THE OVUM. 323 as the general features arc concerned, I believe, belongs to Dr. Marion Sims. It consists in soaking absorbent cotton in carbolized water, (two per cent) and, after pressing out any excess of tiuid, in forming from the cotton a number of flattened disks of about the size of the trade-dollar. After the vagina has been thoroughly washed with a carbolized or boric-acid solution the patient is placed in the latero- prone position, and the perina^uni retracted by a Sims speculum. The dampened cotton disks are introduced by dressing-forceps, and, under the guidance of the eye, are packed first around the vaginal por- tion, then over the os, and thence the vagina is filled in from above downward until the narrow portion above the vestibule is reached. No other plan of tamponing with which I am acquainted can compare in solidity and effectiveness with this. Its removal is accomplished by the detachment with two fingers of a portion at a time. This part of the procedure is moderately painful. Many methods have been sug- gested to overcome in the removal the necessity of introducing the finger into the vagina. A very ingenious one consists in attaching the cotton to a piece of twine so as to form a kite-tail, which can be with- drawn by simply making tractions upon the extremity of the string left hanging outside the vulva. Professor I. E. Taylor uses a roller- bandage. It is efficient, and, like the kite-tail described, can be easily removed. Dr. F. P. Foster * advises the use of the lamp-wicking as a nuiterial for the tampon. No tampon should be allowed to remain in the vagina much over twelve hours, and after its withdrawal, before proceeding to the exami- nation of the uterus, the vagina should be cleansed by an injection of tepid carbolized water ( 3 ij ad Oj). Often the ovum is then found in the upper portion of the vagina or filling up the cervix. If this is not the case, and the cervix is not dilated, so that manual extraction may easily be performed, another tampon should be introduced. It is customary from the outset to sustain the action of the tampon by the administration of ergot, either in the form of the fluid extract (thirty drops every three to four hours), or of a solution of ergotin, given hypodermically (ergotin, gr. xij, glycerin*, 3 j, ten minims twice in the twenty-four hours. In women with abundant adipose tissue the injection should be made into the subcutaneous tissues of the lower abdomen. In others, the outer surface of the thigh should be selected). If the patient is collapsed from loss of blood after tamponing, opi- ates, tea, and alcoholic stimulants should be administered, the latter in small but frequently repeated quantities, until the cerebral anaemia is relieved and the capillary circulation restored. If, after the removal, the cervix is found not to be dilated, a third tampon may be introduced, and left in situ for another period of * Foster, N. Y. Med. Jour., June, 1880. 324 THE PATHOLOGY OF PREGNANCY. twelve hours. The employment of the tampon is not, however, to be recommended for a period much exceeding twenty-four hours. Its continued iise is apt to irritate the vagina. In spite of carbolic acid, it acquires an offensive odor. It generates septic matters, which, in the long run, creep upward through the cervix into the uterine cavity, and produce decomposition of the ovum. I prefer, therefore, in cases of undilated cervix, after twenty-four hours of vaginal tamponing, to resort to tupelo-tents. The tupelo-teut is most easily introduced when the patient is placed upon her left side, with the perina?um drawn back by Sims's speculum, and the anterior lip of the cervix drawn down and steadied by a tenaculum (Sims's method). It may, however, in the absence of an assistant, be introduced, with the patient on her back, by the aid of a pair of strong dressing-forceps. It should be long enough to pass well up through the os internum. Before use the tent should be immersed for a moment in carbolized water, and then dipped in iodoform. Witliin six to twelve hours the tent should be removed, and, after a preliminary vaginal douche, manual extraction be proceeded with in accordance with the rules already given. In manual delivery it is desirable to remove the decidua as well as the ovum. When the cervix is patent this is easy, as the decidua is then detached from the uterine walls. When the cervix is unchanged the detachment is usually incomplete. In such cases it is advisable to resort to the curette, should the symptoms make action necessary. Inside the uterine cavity ovum-forceps should be used with caution. I do not deny its serviceability or convenience on occasions. Its use, however, does not furnish the certainty that the uterine cavity has been completely emptied, which is obtained by the exploring finger. When, however, the retained portions of the ovum have for the most part left the uterine cavity, and occupy the cervical canal, the delivery may at times be advantageously hastened by placing the patient upon her side, and, with the cervix well brought into view by a Sims spec- ulum, applying the ovum-forceps, under the guidance of the eye, within the cervix to the sides of the placenta (Skene). But great care requires to be exercised not to break away the fragile structures and leave material portions behind. Under like circumstances, Hoening* recommended a modification of Crede's method for expression of the placenta. With the patient lying upon the back, the operator, according to Hoening, should seek to compress the body of the uterus between the left hand, laid above the symphysis pubis, and two fingers of the right hand introduced into the vagina. The measure is only practicable when the ovum has, to a great extent, passed from the uterine cavity. It is more likely to be followed by the retention of the decidua. As it is somewhat painful, * Hoening, Scanzoni's Beitrage, Bd. vii, p. 213. THE PREMATURE EXPULSION OF THE OVUM. 325 and requires for success lax abdominal parietes, it possesses a limited range of applicability. Treatment of Neglected Abortion.— Where, following abortion, the uterus has once been completely evacuated, haemorrhage ceases. A slight lochial discharge persists for a few days during the period in which the uterine portion of the decidua vera completes its period of repair. If, therefore, a patient comes to us two or three weeks after the supposed conclusion of an abortion, with the story of recurrent haemorrhages taking place, as a rule, wdienever she leaves her bed and assumes the upright position, it may be assumed, with an approach to certainty, that portions of the ovum still remain within the uterus. Oftentimes a fetid discharge points to the fact that decomposition has been set up. The absorption of septic materials may, furthermore, become the source of chills, of fever, and of great uterine tenderness. In most cases, with rest in bed, the contents are discharged by sup- puration, and recovery ultimately takes i)lace, but only after a slow, protracted convalescence, during which pelvic cellulitis and pelvic peritonitis occur as not uncommon complications. Haemorrhages, peritonitis, and sei^ticfemia may, however, bring the case to a fatal issue. The removal of the retained placenta and membranes is there- fore indicated, not only as a measure calculated to promote recovery, but to avert possible danger to life. AVith regard to the operation for removal, the rules already given are applicable. The following peculiarities should, however, be borne in mind. In case the retained portions are undecomposed, the cervix is usually found closed, and requires preliminary dilatation with the tent. When decomposition has once set in, the os internum will, as a rule, allow the finger to pass into the uterus.* When a decomposed ovum is removed by the finger, a chill and a septic fever — which rapidly disappear, however — are apt to follow in the course of a few hours. This chill and fever result from the slight traumatic injuries inflicted by the finger upon the uterine walls, wdiereby the capillaries and lymphatics become opened up to the action of the septic poisons. The fever ends in a short tinie, because the reservoir of supply is re- moved with the debris of the ovum. If the uterine cavity, after the operation, is carefully washed out with carbolized water, the septic fever is often averted. After the irrigation a strip of iodoform gauze pushed upward to the fundus with ovum-forceps acts beneficially both as a means of disinfection and as a safeguard against luemorrhage. The packing can be left in situ for twenty-four hours. The improve- ment following the complete emptying of the uterus in these cases is so decided, that of late years I have not allowed myself to be deterred from proceeding actively, even when perimetritis and parametritis, in not too acute a form, already existed. In practice, multitudes of * HtTER, Compendium cler geburtshiilflichcn Operationcn, Leipsic, 1874. p. 32. 326 THE PATHOLOGY OF PREGNANCY. examples show that the products of inflammations situated in the pelvis do not become absorbed so long as putrid materials are generated in the uterine cavity. The removal of a fibi'inous polypus, owing to its smoothness and the small size of the pedicle, is often a Sisyphus's task. The separation can only be successfully accomplished when the palmar surface of the index-finger presses from above upon the point of attachment. This necessitates a choice of hands. Thus, when the polypus is situated to the left, the right index-finger sliould be employed, and the left index-finger when the polypus is situated to the right. After the detachment is complete, it is necessary to press the polypoid body firmly against the uterine walls, and proceed with its withdrawal slowly. If, as is sometimes the case, the polypus slips from under the finger, the latter should be again passed to the fundus of the uterus, and the attempt repeated. Snuill portions, not larger than a pea, can be washed out by the uterine douche. When the polypus is situated near the os internum, tlie latter will be found patulous, but when it is well up within the body of the uterus, dilatation is a frequent prerequi- site to removal. For the removal of presumably small jiortions of retained ovum, especially in cases where, owing to inflammatory conditions, I have hesitated to make the circuit of the uterine cavity with my finger, I have succeeded admirably by employing a toleral)ly firm Thomas's wire curette.* The Treatment of Immature Deliveries. — Fourth to seventh month. — Distinctive of immatui-e deliveries are : painful periodic contrac- tions, recognizable by the liand applied above the symphysis pubis, rupture of the membranes and discharge of the foetus, the complete formation of the placenta and umbilical cord ; while in abortion the uterine contractions are obscure, the placenta is rudimentary, and the ovum is frequently expelled entire. In the treatment of immature delivery the tampon may usually be discarded. After rupture of the membranes and expulsion of the foetus, the haemorrhage should be controlled by grasping the fundus of the uterus in the hand through the abdomen, and compressing the uterine walls firmly together. The passage of the fcetus opens the uterus so as to allow, in the fourth and fifth months, the introduction of two fingers ; in the sixth and seventh months, that of the half-hand. In case compression of the uterus does not arrest the hemorrhage and expel the placenta, the cord should be carefully followed to its insertion, to determine the * Skene, Med.

If the placenta is implanted upon the right side, two or four fingers of the right hand, according to the degree of cervical dilatation, should be passed up along the left side of the uterus, across the fundus to the placental site. The de- tachment should be effected with the tips of the fingers, and the pla- centa pressed downward as the fingers descend along the right side of the uterus. The left hand should be employed in the reverse direc- tion, when the placenta is situated to the right. CHAPTER XVII. EXTRA-UTERINE PREGNANCY.

After coitus, the spermatozoa may make their way through the Fallopian tubes to the pelvic cavity. It is possible, therefore, for the ovum to become fecundated in any portion of the route from the ovary to the uterus. In exceptional cases, the ovum may, after fecundation, be arrested in its travels, and undergo development at some point out- side the uterus. To these cases the term extra-uterine pregnancy has been applied. In the past it has been assumed that the ovum may develop within the tube, in the ovary, or in the abdominal cavity — hence the terms tn'hal., ovarian, and abdominal pregnancii; but modern research has thrown doubt ujDon the existence of the two latter varieties, as a jsri- mary condition. In any event they are extremely rare. In Mr. Tait's* belief, all cases of extra-uterine pregnancy are nb initio of tubal origin. When the ovum develops in the free part of the tube, rupture, he holds, occurs at or before the fourteenth week. If rujjture occurs at once into the abdominal cavity, death ensues from haemorrhage, or later from .suppuration of the sac and peritonitis ; if rupture takes ])lace in the lower portion of the tube between the folds of the broad ligament, the ovum may develop to full term ; may die and be absorbed as an extraperitoneal haematocele ; may supjju- rate and be discharged at or near the navel, or through the bladder, the vagina, or intestinal tract ; may remain quiescent as a litho]);edion ; or may be- come an abdominal pregnancy by secondary rupture. In the tubo-uterine or interstitial form death occurs from intraperitoneal rupture before the fifth month. Mr. Tait denies the possibility of a primary abdominal pregnancy. The ovarian form he regards as possible but not proved. *Tait, Lectures on Ectopic Pregnancy and Pelvif Ila-matocele. 328 THE PATHOLOGY OF PREGNANCY. Tubal Pregnancy. — The ovum may find lodgment in any part of the tube. The cause of this anomaly is most frequently to be found in the various forms of chronic salpingitis. Owing to the associated loss of epithelium, the dilatation and other changes in the tube walls, the two active forces which propel the ovum through the tube — viz., ciliated movements and peristalsis — are weakened or destroyed, while free ingress is afforded to the spermatozoa. Or, again, the passage of the ovum may be interfered with by the secondary results of catarrhal inflammations — such as the production of mucous polypi, of adhesions, or of sac-like dilatations. Formerly great stress was laid upon the etiological importance of flexions and constrictions resulting from old peritoneal adhesions and inflammatory bands. Curiously enough, in recent laparotomies for tubal rupture this cause has not played an im- portant part. It is not quite clear whether the peritonitis formerly observed so frequently at autopsies was not in most instances second- ary. It is, moreover, possible that as a class, in cases where ante- cedent peritonitis has existed as a cause, the hemorrhages result- ing from rupture, owing to the agglutination of intestines and pelvic organs, are circumscribed, and do not call for surgical measures of relief. Because of its connection with inflammatory processes, the occur- rence of tubal pregnancy is often preceded by a long period of sterility. When the obliteration is only partial, the spermatozoa, owing to their small size, are not prevented from reaching the arrested ovum ; when complete, on the contrary, they can only gain access to the ovum by first passing through the patulous tube, and then migrating across the rear of the uterus to the ovary or the open abdominal end of the tube upon the opposite side. In a considerable number of cases, the corpus luteum has been found upon the side opposite to the tube containing the fecundated ovum. With the present prevailing views,* this phe- nomenon is only to be accounted for by the hypothesis of the migra- tion of the ovum across the peritoneal surface of the pelvis or through the uterus from one tube to the other. Kecent observations have shown that there is a tendency for tubal pregnancy to recur. Thus Herrmann has reported a case where, in performing laparotomy for tubal rupture, he found the remains of an ovum in the other tube. Tait f has reported one and Veit J three cases where, within a year or two after a first operation for tubal rupt- * Mayrhofer, Ueber die gelben Korper, und die Ueberwanderung des Eies, de- nies the whole doctrine of a distinct corpus hiteum of pregnancy, and claims that corpora lutea are found at stated intervals, perhaps monthly, throughout the entire period of pregnancy.

Gynaek., Bd., xvi, p. 24, however, found that after tying the right tube and removing the entire left ovary in a couple of rabbits pregnancy still took place. + Tait, British Gynaecological Journal, August, 1888. p. 178.

EXTRA-UTERINE PREGNANCY. 329 ure, a second laparotomy was rendered necessary because of the occur- rence of pregnancy into the tube of the opposite side. Tubal i^regnancy is associated with the formation of a uterine de- cidua which differs in no wise from the decidua of pregnancy, except that the distinction into three layers is less marked. In the tube a decidua likewise forms around the ovum. It contains large epithelioid cells, as in uterine" gestation. It differs, however, from the latter in the presence of connective-tissue fibers between the cell groups, and in that next to the muscular coat there is a transition zone in which cells and muscular and connective-tissue fibers are inter- mingled. Klein * has reported the existence of decidual tissue be- tween the villi in a specimen removed from a patient in whom rupt- ure occurred seven weeks after the last menstruation. In more ad- vanced cases there is no serotina, nor is there any maternal portion to the placenta. The club-shaped extremities of the villi simply impinge Fio. 137.— Intraperitoneal rupture of tube. on the muscular walls. Concerning the decidua reflexa opinions are conflicting. Frommel and Winckel maintain its existence. None was discovered by Langhans, Leopold, Klein, and the majority of later investigators. In Klein's cases tubal vessels opened directly into the spaces between the villi. In the early months the development of the ovum leads to a spindle-shaped dilatation of the tube, associated with hypertrophy of the muscular walls due to increase in the length and thickness of the individual fibers. As regards the degree of hypertrophy, very great * Klein, Zur Anatomie der Scliwangeien Tulic. Zeitschr. fUr Geburtshiilfe und Gynaek., vol. xx, p. 288 et seq. 330 THE PATHOLOGY OF PREGNANCY. individual variations have been observed. Indeed, in the same sac a thickening at one point may be accompanied by an excessive degree of tenuity due to eccentric growth of the ovum at another. Now, the ultimate fate of a tubal pregnancy is in large measure dependent upon these anatomical differences. Unquestionably, early rupture is the =3 i^ rule. Mr. Tait says : " Out of an enormous number of specimens which I have examined, I have entirely failed to satisfy myself that rupture has been delayed later than the twelfth week." It seems to me, however, carrying skepticism too far to refuse credence to the positive observa- tions of others, made apparently with the utmost care and with full EXTRA-UTERINE PREGNANCY. 331 knowledge of possible sources of error, which seem to show that a tubal pregnancy may exceptionally reach advanced or even the full term of pregnancy. At present it seems fair to assume that, when the sac which surrounds the ovum is composed of muscular and connective-tis- sue fibers with an external peritoneal envelope, and directly communi- cates with the Fallopian tube, the sac walls are of tubal origin. Of course it is not possible to assert that no rupture has taken place in the course of development. It is only known positively that rupture occur- ring at the site of placental attachment gives rise to hemorrhage fatal to the fa?tus ; and the same is true, with rare exceptions, where rupture occurs at any jjoint of the peritoneal surface. That rupture has first occurred into the cavity of the broad ligament in all the cases which go on to the period of viability does not seem so absolutely certain. The anatomical appearances, in some instances at least, indicate that the exposure of the fetal membranes here and there through the maternal sac results not so much from laceration as from the gradual separation of the muscular fibers due to excessive stretching.* In most of the cases in Avhicli the pregnancy reaches an advanced stage the develop- ment of the tube takes place principally between the folds of the broad ligament. The support furnished the tubal sac by the gradual unfold- ing of the ligament layers hinders rupture. More rarely pregnancy may go to the period of viability Avithout encroaching upon the intra- ligamentous space. The tumor then rises above the pelvic brim, and is furnished with a species of pedicle consisting of the uterine end of the tube and of the broad ligament. The first of the above, or the intraligamentous form, lies close to the uterus, which it not infrequently crowds upward and forward. The uterine end of the tube varies greatly in length. The fimbriated extremity is unrecognizable. Usually no traces of the ovary are found. In the so-called pedicled form the uterus is crowded to one side or re- tro verted. The uterine end of the tube is usually long and thickened. The corresponding ovary has generally been discovered. In both cases the relations of the sac are often obscured by adhesions to adjacent viscera. In the second half of pregnancy rupture of the sac and the escape of the foetus into the peritoneal cavity may occur without no- ticeable h;i?morrhage or without interruption of pregnancy. As the pressure is removed by the escape of the amnrotic fluid, the placental borders curl inward so as to furnish a cup-like space, while the mem- branes sink downward and cover the upper placental surface. The fu?tus in these cases may occupy the abdominal cavity, or a sac may be formed by the agglutination of the adjacent viscera. Werth has reported a case in Avliich death of the embryo occurred in the second month, and was followed by haemorrhage which i)0ured * Vtde tables of Wertli.

Similar observations have been made by Veit and Westermark. This form Werth terms tubal abor- tion, in another case described by Wyder the fimbriated extremity of the tube was obliterated, and as a consequence the hemorrhage follow- ing the separation of the ovum converted the ampulla of the tube into a blood cyst the size of the fist.* Pregnancy in the Rudimentary Cornu of a One-horned Uterus.— This anomaly so closely resembles the tubal form of pregnancy that the diagnostic distinction can rarely be established during life. In tubal pregnancy rupture takes place, as a rule, in the first three months, while the rupture of the cornu occurs somewhat later, usually between Fig. 139.— Pregnancy in rudimentary cornu. (Kussniaul, observed bf Heyfelder.) the third and sixth months. Cases have, however, been reported by Turner,! Werth,J and Salin,* in whicli gestation went to full term. Rupture takes place at the apex of the cornu. In several instances in which surgical procedures have been employed for this anomaly, the removal of the entire sac has been rendered easy by the presence of a well-formed pedicle. Interstitial Pregnancy. — The term interstitial pregnancy is applied to cases in which the ovum is developed in the uterine portion of the * Op. cit., pp. 105, 106. X Archiv f.

The latter measures about seven lines in length by one line in diameter. At first the muscular walls hypertrophy and form around the ovum a sac which projects from the upper angle of the uterus. As, ordinarily, the growth of the muscular tissue does not keep pace Fig. 140.— Interstitial pregnancy. (Hennig.) with that of the ovum, rupture occurs at an early period. Of twenty- six such cases collected by Hecker, all ruptured before the sixth month. Tait says that, " so far as known, interstitial pregnancy is uniformly fatal by primary intraperitoneal rupture before the fifth month." Schwarz,* however, reports a case belonging to this category in which the foetus was expelled into the uterine cavity. The patient was known to be pregnant. Repeated ha?morrhages indicated a threatened abortion. To avoid further dangers, the cervix was dilated with the view to empty the uterus. On examination with the finger the uterine cavity was found empty, but there was a piece of membrane at the uterine opening of the left tube, wliich was removed. The next day the finger detected membrane at tlie same site, and, be- yond, a hard body. The uterus began to contract energetically. On * Schwarz, Wiener nied. Blatter, 1886. In the abstract furnished by Grandin in the American Journal of Obstetrics (January, 1887, p. 101). the date of pregnancy IS not given. Similar cases have been reported by Dr. Charles :McIiurney (New York Med. Jour., March, 1878, p. 273) and by Dr. Cornelius Williams (in the De- cember number of the same journal, p. 595), both of which were followed by the re- covery of the mother. 334 THE PATHOLOGY OP PREGNANCY. the fifth clay a foetus was passed by the vagina, the pains ceased, the tumor largely disappeared, and the f)atient made a good convalescence. Martin removed a male foetus 33 centimetres long (six months) from the left uterine cornu. The patient recovered. Duvelius, who examined the specimen, concluded that the ovum had 2)artially grown into the tube and between the folds of the broad ligament. He thought that rupture did not occur owing to the number of the muscu- lar elements in the sac wall.* A possible form of interstitial pregnancy is furnished by the occasional existence of a canal, open at its two extremities, and appar- ently a continuation or a bifurcation of the Fallopian tube. A case reported by Dr. Gilbert, in the Boston Medical and Surgical Jour- nal (March 3, 1877), where the head of the child could be felt just above the os internum, covered by a thin mucous membrane, and in which delivery was successfully accomplished by an incision through Fig. 141.— Bifurcation of tubal canal. (Hennig.) the partition, probably belonged to this variety. A similar case, in the practice of Dr. H. Lenox Hodge, is reported by Parry {op. cit., p. 266). In the post-mortem examinations the distinction between an inter- stitial pregnancy and one in a rudimentary cornu is not easy to make out. The chief points of difference consist in the fact that in inter- stitial pregnancy the sac communicates by an orifice with the uterine cavity, or is separated from the uterus by a partition, while in preg- nancy in a rudimentary cornu the two halves of the uterus are united by a muscular band, which is situated not at the upper angle but near the OS internum. Ovarian Pregnancy. — In spite of modern skepticism, there is little question as to the occasional occurrence of ovarian pregnancy. The specimen discovered by Patenkof in the Pathologico- Anatomical Museum of St. Petersburg seems to answer all the requirements of a * Martin, Ztschr. f. Geb und Gynaek., vol. xi, p. 416. f Patenko, Casuistische Mitteilungen, Arch. f. Gynaek., vol. xiv. p. 156. EXTRA-UTERINE PREGNANCY. 335 demonstration. The right ovary was of the size of a hen's egg, and contained a cyst with smooth walls filled with serum. In this he found a body of a yellow color, of the size of a hazel-nut, which contained cylindrical and flat bones. The most careful microscopical examina- tion established the fact that the bones were those of a foetus, and not merely the chance products of a dermoid cyst. The presence of corpora lutea and follicles in the walls of the envelope proved that the body was an ovary. The tube on the corresponding side was nowhere adherent to the sac. The abdominal extremity was closed, and there were no traces of fimbriae.* Paltauf f relates a case of extra-uterine pregnancy in which there was a sacculated condition of both tubes which communicated with a cyst of ovarian origin. The ovaries were closely united. By means of the ovarian cyst a complete communication was established between the two tubes. In the large central ovarian cyst a clot was found which contained an embryo corresponding in size to one of from forty- five to forty-eight days' development. The origin of the condition here met with is naturally a matter of speculation. Abdominal Pregnancy. — In most cases of abdominal pregnancy a connective-tissue proliferation is set up about the ovum, which sur- rounds it with a vascular sac. The latter often attains a degree of thickness which renders it comparable to the gravid uterus (Klob). The walls keep pace, as a rule, with the growth of the ovum, and, as they extend into the abdominal cavity, form adhesions to the intestines, the mesentery, and omentum. It is claimed that organic muscular fibers have been found in the sac, especially near the uterine attach- ment. In this form the foetus most frequently reaches maturity. In rare cases the ovum develops free in the abdominal cavity, with- out the formation of pseudo-membranes, the foetus being surrounded solely by the amnion and chorion. The greater number of so-called abdominal pregnancies are un- questionably of tubal origin. In reality they are for the most part extraperitoneal, and result from a rupture in the tube walls occurring between the folds of the blood ligament. In these cases the conditions are not incompatible with continued fetal development, and gestation may reach an advanced stage. The question as to the occurrence of primary abdominal pregnancy must be regarded as unsettled. The discovery of an ovum growing in * Mr. Tait, in his recent work on Ectopic Pregnancy, refers to a specimen de- scribed by Dr. Walter as one of primary ovarian pregnancy (sac had ruptured at fifth month, and foetus had escaped into peritoneal cavity), which is now in the Dorpat Museum, and suggests a careful investigation as to its real character. At Werth's request this has since been made by Runge, with a complete confirmation of the significance given to it by Walter in his original publication. Werth, loc. cit., p. 64. f Paltauf, Arch. f. Gynaek., vol. xxx, p. 4.j(5. 336 THE PATHOLOGY OF PREGNANCY. the peritoneal cavity with the tubes and ovaries demonstrably intact would suffice to establish the abdominal variety. In the early months, before the anatomical conditions are obscured by secondary changes, there is no pretense that such proof has been obtained. In more ad- vanced stages a good many cases of assumed abdominal pregnancy have been placed in evidence. These, so far as my investigations per- mit me to judge, are divisible into two classes : 1. Cases where the tubes are reported as intact, but in which there exists a direct communication between the tube upon the affected side and the sac cavity. Thus Treub, of Leipsic reports the following instance : Patient menstruated last about the middle of April, 1887 ; perito- nitic pains, with symptoms of internal haemorrhage, on tlie ll^th of June. At the end of July the same symptoms occurred, but were more violent. Ballottement was distinct by the end of September. Life was felt a week later. There were no fetal movements after November 24th. Septic symptoms developed, and laparotomy was performed January 22, 1888, when the patient was nearly moribund. Death en- sued the following night. At the autopsy the annexa on the right side were normal. The left tube measured ten centimetres and a half, which corresponded to the length of the right tube. It was pervious throughout its entire ex- tent. The fimbriated outer end communicated with the sac. There was no apparent distention of the abdominal end of the tube. The sac of the ovum was adherent to the posterior surface of the uterus and of the broad ligament, to a few coils of intestines, to the sigmoid flexure, and to the rectum. Abdominal pregnancy was assumed by Treub because the tube had its normal length and its natural direction, while the placenta was attached to the posterior sac wall, which contained no muscular ele- ments, even in the vicinity of the tube. It has been suggested, how- ever, that this was a case where the fecundated ovum occupying the infundibulum ruptured the tube walls at an early period of its growth, and thence continued its development between the folds of the broad ligament. It will be remembered that there were unmistakable symp- toms of internal haemorrhage in June and in July. The length of the left tube does not affect the question, as Werth * furnishes cases of un- mistakable intraligamentous development where the same feature was noted. 3. Cases where the tubes are reported as intact and not in commu- * Werth, Beitrage zur Anatomie und zur operativen Behandlung der Extra- uterinschwangerschaft, 1887.

EXTRA-UTERINE PREGNANCY. 337 nication with the sac. Few of these merit criticism. Lately, however new interest has been excited as to the possibility of primary abdomi- nal pregnancy by a case operated upon in 1879 by Professor Miiller,* of Bern. Extra-uterine and intra-uterine pregnancy existed at the same time. At the eighth month spontaneous expulsion of the intra- uterine foetus took place. The extra-uterine ovum Avas removed bv laparotomy. Death ensued from ha?morrluige. The post-mortem in- vestigation was conducted by Walker, who, in a carefully prepared essay, concludes that the case Avas a typical one of abdominal preg- nancy. The tubes and ovaries were in contact, but not adherent to the sac. The latter had started originally from the bottom of the cul-de-sac of Douglas, and only in the course of its subsequent develop- ment had reached the uterine appendages. The correctness of the author's deductions has not, hoAvever, passed unchallenged, most of the recent reviewers regarding the history as indicating a tubal origin. Schlectendahl f reports the discovery of an ovum near the spleen, containing a foetus measuring fifteen centimetres in length, in a woman who had died from internal hsemorrhage. The sac Avas the size of a man's fist, and Avas surrounded by adherent intestines. The uterus and tubes appeared normal. ' The value of this case as evidence on behalf of abdominal pregnancy has been denied, but the facts related by Schlectendahl certainly call for explanation. Of very great interest are the cases of so-called secondary abdomi- nal pregnancies, where rupture of the sac and the fetal membranes takes place and the foetus passes into the abdominal caA^ty. Most often the child dies at or soon after the time of rupture, but cases are reported by Walter, Patuna, and Bandl,J where it continued to de- velop within the abdomen. The presence of the child usually excites an active proliferation of connective tissue, by means of which a sec- ondary sac is formed, though in Jessup's case the child was absolutely free in the abdominal cavity. If the child dies, it may either become converted into a lithopaedion, or, through the vascular connective tis- sue by Avhich it is surrol^nded, the soft structures'of the body may pre- serve their integrity for years succeeding the fatal ending. There are, in addition to the varieties already mentioned, histories on record of the coexistence of extra-uterine and intra-uterine preg- nancies, the latter occurring at the same menstrual period as the for- mer, or subsequent to the death of the extra-uterine foetus.* * Vide L.

Tubo-Abdominal and Tubo-Ovarian Pregnancy.— When the ovum becomes lodged near the trumpet-shaped extremity of the Fallopian tube it may grow outward into the abdominal cavity. Local peritonitis is then set up, and plastic exudation is thrown out, forming an envelope around the ovum, which is likewise bounded by the contiguous organs. In tliis way the ligamenta lata, the ovaries, the mesentery, the in- testines, the bladder, and the uterus, may all contribute to the invest- ment of the fetal membranes. In case of rupture in the tubal portion inflammatory products may form, and limit the extent of the injury. At first, owing to its weight, the distended tube drops into the cul- de-sac of Douglas. In advanced pregnancy, the spleen, kidneys, and liver may become involved, and form part of the sac-walls around the ovum. Usually the placenta is developed in the pelvic cavity.* When the investment of the ovum is furnished by the tube and the ovary, the term tubo-ovarian pregnancy is employed. The course in either case does not materially differ from that of an abdominal pregnancy. The Symptoms of Extka-uterine Preg^tancy. The earlier symptoms of extra-uterine preg^nancy do not materially differ from those of the intra-uterine form. Menstruation usually ceases, though not with the same regularity as in normal pregnancy. The recurrence of the monthly flow for one or two periods is not an uncommon incident. In some cases, too, a nearly continuous sero- sanguinolent discharge of moderate extent has been observed;^ Up to a certain point the hypertrophic changes of the uterus take place in the usual manner. The mucous membrane is converted into a de- cidua, and a mucous plug fills the cervix. In general terms, the length of the uterus is greater the closer the contiguity of the ovum to the uterus. In a few cases of tubal pregnancy there has been no increase in the size of the uterus. The extra-uterine ovum may, in the course of its growth, drag the uterus upward, or push it downward, forward, or to the side, according to the site of its development. Characteristic symptoms of extra-uterine pregnancy do not occur until the ovum has reached a certain degree of growth, and in some cases not until rupture has taken place. Often preceding rupture, or, in abdominal pregnancies, the death of the foetus, the patient suffers from paroxysmal pains in the sac, and uterine pains of a labor-like character. The latter are associated with a sero-sanguinolent dis- charge, and are followed by the expulsion of portions of the decidua. The symptoms of rupture are the usual ones of internal haemor- rhage, viz., yawning, languor, fainting, clammy perspiration, rapid pulse, intermittent vomiting, collapse, and acute anaemia. After the * Vide Bandl, Billroth's Handbuch der Prauenkrankheiten, 5ter Abschnitt, p. 47. EXTRA-UTERINE PREGNANCY. 339 death of the ovum these symptoms may cease and not return again ; whereas, if the ovum continues to grow, there may be repeated attacks of haemorrhage and local peritonitis. When the death of the ovum does not occur within the first three to four months, the pressure of the tumor usually gives rise to dysuria and constipation. Terminations. — The investigations resulting from the recent wide- spread interest in the diseases of the uterine appendages have shown that tubal pregnancy is by no means of rare occurrence. Whereas, in tubal and interstitial pregnancies, it was formerly believed that the usual terminations were rupture of the sac, h£emorrhage, peritonitis, and death, it is now known that in a pretty large percentage of cases the ovum perishes at an early period of development; and, though the sequelae of these so-called tubal abortions may cause discomfort or lay the foundation for chronic invalidism, they do not necessarily lead to a fatal result. As in cases of uterine abortion, the death of the ovum is for the most part followed by haemorrhage, which may be confined to the tube (haematoma tubae), or the blood may escape by the fimbri- ated extremity into the peritoneal cavity, or, if circumscribed by adhe- sions, it may give rise to the intraperitoneal form of pelvic haematocele. Even when rupture takes place the haemorrhage is not necessarily fatal. Mr. Tait insists on the relative harmlessness of most cases of haema- toma due to rupture occurring between the folds of the broad ligament ; while the records of salpingotomy show that, even with intraperi- toneal rupture, the haemorrhage has often been found moderate in amount, and did not in itself furnish the occasion for surgical inter- ference.* In abdominal pregnancies, which it has been seen are usually if not always secondary to the tubal form, the ovum or foetus, as a rule, excites a local peritonitis, attended with pain and fever, and followed by the production of pseudo-membranes, which exercise a conservative influ- ence by shutting off the ovum from the peritoneal cavity. Indeed, in the exceptional instances where these inflammatory conditions do not develop, the movements of the foetus within its own membranes may give rise to such intense suffering as to cause the woman to die from exhaustion (Schroeder). In abortions at an early stage it often happens that no trace of the embryo is found, and the diagnosis has to be made from the presence of the chorionic villi. Even when abortion does not occur in the first few weeks the child is apt to die prematurely. Sometimes, however, gestation may advance to full term ; in which case labor-pains set in, the decidua is expelled, and the child dies during the expulsive efforts. In the majority of cases the dead foetus excites a suppurative inflammation in the sac by which it is inclosed, and the patient dies * Vide, as an instance, the cases reported by Orthman from Martin's Clinic. 340 THE PATHOLOGY OF PREGNANCY. either from general peritonitis or from profuse suppuration. In cases where the peritonitis remains local and the suppuration is tolerated, fistulous communications may form with one of the hollow viscera or the abdominal walls, through which the contents of the sac may be eliminated. Most frequently the opening takes place into the large intestine ; quite often through the abdominal walls ; more rarely into the vagina and bladder. In any case, the process of elimination is slow, often lasting months, and even years. When the bones and soft tissues have all been discharged, complete recovery may take place. In the larger proportion of cases, however, if Nature is not assisted, the patient perishes from exhaustion and blood-poisoning before the elimi- nation is ended. Sometimes the foregoing inflammatory changes do not occur as the result of the death of the foetus, in which case the fluid contents of the sac are re-absorbed, and the walls collapse and come in contact with the fetal cadaver. The skin of the latter, and at a later period the deep-seated soft tissues, undergo fatty degeneration, and form a greasy substance consisting of fat, lime-salts, cholesterin-crystals, and blood- pigment. Afterward the fluid portions are absorbed, so that nothing remains but the bones, lime lamellee, and incrustations upon the walls of the sac ; or the foetus may shrink up like a mummy, preserving its shape and organs to the minutest detail. A foetus thus altered is termed a lithopaedion. It may remain imbedded in connective tissue for years without injury to the mother. The lithopaedion of Leinzell was removed in 1720 from a woman ninety-four years of age, who had carried it for forty-six years. The presence of the lithopaedion does not prevent pregnancy from taking place. In some cases it may after years excite suppuration, a result which is fostered, according to Spiegelberg, by pregnancy and labor. Recovery may follow the -artificial extraction of the foreign body, or death may result from inflammation and the discharge of pus. Note. — Kiichenmeister (Ueber Lithopadien, Arch. f. Gynaek., vol. xvii, p. 153) distinguishes three conditions to which the term lithopaedion is applied : 1. Where, after absorption of the fluid, the membranes alone calcify, and the foetus undergoes mummification. 2. Where, after absorption or escape of the fluid, the membranes calcify, and calcification of the foetus occurs at points where the membranes adhere to the fetal surface. 3. Where the foetus escapes into the abdominal cavity, and cretaceous matter is deposited in the smegma covering the fetal surface. In this way calcified strata form around the foetus and exert compression upon the contained tissues. Beneath the chalky layers the tissues are mummified. A lithopaedion in the sense of a com- plete petrifaction does not exist. Diagnosis, — The diagnosis of extra-uterine fetation is based upon the existence of the signs of pregnancy, the exclusion of an ovum within the uterine cavity, and the presence of a tumor external to the uterus. EXTRA-UTERINE PREGNANCY. 341 In practice, however, there is a wide-spread difference of opinion as to the practicability of an early diagnosis ©f tubal pregnancy. Dr. Hanks has recently stated his belief that a diagnosis can be made in ninety-five per cent of the cases we are called upon to attend. Mr. Tait, on the other hand, thinks " he may be excused for maintaining a somewhat skeptical attitude concerning the correctness of the diagno- sis of these gentlemen who speak of making a certain diagnosis before the period of rupture." The problem seems simple enough. Given pregnancy, and having ascertained that the ovum is not in the uterus, the diagnosis is effected. But we all know that the subjective symptoms of pregnancy are decep- tive, and that the pigmentation, the mammary, and the utero-vaginal changes are not always so clearly defined in the first three months as to make it safe in every case to positively diagnosticate pregnancy in even the intra-uterine form. The advice to use the sound to demon- strate the vacuity of the uterus in suspected cases has been the cause of many needless abortions. Fortunately, the sound often does no other harm than to add to our sources of error. Twice within a year gravid patients have been sent to me with the assurance that the re- peated introduction of the sound had shown the empty condition of the womb. In one of them, after an anaesthetic was given, it was easy to determine the presence of the head of the child through the cervix at the internal os ; in the other I felt perplexed, and asked the opinion of Dr. Thomas. He pronounced it an ordinary pregnancy, and the event has shown that he was correct. Twice within a year, to my knowledge, the abdomen has been opened in this city for supposed extra-uterine gestation, and only ordinary gravidity was found. In the main, our dependence must be upon local changes and local symptoms. Thus a tubal swelling and enlargement of the uterus, as- sociated with suppression of the menses, often followed after a brief period by sero-sanguinolent discharges and increased flow at the men- strual period, with paroxysmal pains radiating from the side of the pelvis upon which the affected tube is situated, and with the expulsion of the uterine decidua at the end of the second or in the course of the third month, are to be regarded with suspicion. But a tubal sac is the product of a variety of pathological conditions.* The uterine changes in early months are inconstant. These sometimes correspond to those of ordinary uterine gestation, but often there is neither perceptible en- largement nor cervical softening to indicate pregnancy. Paroxysmal pains are frequent in other forms of tubal disease, and menstrual disturbances are common phenomena in uterine derangements. The * Veit regards as an important distinction in the early stage, that whereas in other forms of tubal enlargement the swelling may be hard or tense or fluctuating, when due to an intact ovum it possesses a characteristic soft feel. Verhandlungen der Deutschen Gesellsch. f. Gynaek., Third Congress, Leipsic, 1890, p. 162. 342 THE PATHOLOGY OP PREGNANCY, expulsion of the decidua, though a valuable sign, is not of constant occurrence. In many tubal abortions the only symptoms are those of pelvic hajmatocele. In many instances of early rupture of the tube with hajmorrhage into the peritoneal cavity there are no antecedent symptoms, or only those of ordinary pregnancy. In reading the re- ported cases of the operative removal of pregnant tubes, it is surprising to note in how many of them the diagnosis was only established by the subsequent determination in the removed tubes of decidual cells and chorionic villi. Undoubtedly a probable diagnosis prior to rupture might be made in many instances if the patients could be subjected to frequent examinations from the beginning of the pregnant state, but this, in the nature of things, is rarely. practicable. In the intraligamentous form the conditions for diagnosis are more favorable. Here gestation is apt to be prolonged, and if rupture occurs between the folds of the broad ligament the hemorrhage is limited in amount. In this class the patients are apt to seek early professional advice, owing to the discomforts from which they suffer. The swelling at the side of the uterus is easily reached through the vagina, and we have as distinctive signs a rapidly growing tumor, early fluctuation, and the presence of pulsating vessels over the site of the tumor. Bimanual examination under an anaesthetic, especially if the thumb be introduced into the vagina and two fingers into the rectum, makes it possible to determine that the tumor is independent of the uterus.* After the third month it is not ordinarily difficult to determine the existence of the pregnant state. Ballottement is usually perceptible at an early date, and the fetal heart makes the diagnosis certain ; but the greatest care needs to be exercised in the examination of the patient and in the formation of an opinion concerning the extra-uterine situa- tion of the ovum. In a suspected case violence in the attempt to separate the tumor from the uterus may cause sac rupture. Grand in believes the absence of contractions when frictions are applied to the sac of an extra-uterine ovum should prove a most valuable aid to diagnosis. Kiistner f curiously enough maintains that the existence of contractions in tubal pregnancy should distinguish them from other pelvic growths. Mr. Tait cites as a misleading condition an abnormal thinness of the uterine walls. In my own experience, lateral flexion of the uterus often simulates ectopic gestation to a surprising degree. In these cases the fundus containing the ovum lies upon one side of the pelvis. The cervix is crowded to the opposite side. Between the two * According to Smolsky's observations, the tube in the first two months is the size of a pigeon's egg, at the end of the second month of an English walnut, at two and a half months of a hen's egg, at three months it reaches the size of the fist, and at four months the size of two fists. Variations may result from hydramnion, haMnato-salpinx, malformation, etc. Smolsky, Diagnostie et traitement de la grossesse tubaire, Neuvelles arch, d'obstet. et de gynecologie, Dec, 1890, p. 649. f MtJLLER's, Handbuch der Geburtshlilfe, a'oI. ii, part 2, p. 541. EXTRA-UTERINE PREGNANCY. 343 a deep sulcus is felt. If the patient is hysterical, these deranged rela- tions are exaggerated by contraction of the abdominal muscles. No difficulty in detecting the error 'is experienced when the patient is anaesthetized, except in cases where the fundus is fixed to the side by adhesions. In two instances seen by me the intra-uterine nature of the pregnancy was only determined by the forcible introduction of the finger through the cervix. Cases of retroflexion of the gravid uterus with incarceration are likewise often difficult to distinguish from extra- uterine pregnancy. The distinction by physical signs between the tubal, the ovarian, and the secondary abdominal form is scarcely practicable so long as trained anatomists fail to agree concerning them when the abdomen has been opened and the organs are exposed to view. A review of the subject of diagnosis makes it apparent that many cases of ectopic pregnancy present no symptoms previous to rupture. In another class the existence of a suspicious tumor with few or none of the corroborative signs should lead to a waiting policy, or, when the symptoms are of a threatening character, to an explorative laparotomy. It is well, however, to remember that with reference to this latter pro- cedure recent popular interest in abdominal surgery has a tendency to invest trifling anomalies occurring in gestation with a sinister impor- tance. But there still remains a considerable class in which an early diagnosis can be reached with reasonable certainty.* Treatment. — The treatment of extra-uterine fetation varies in ac- cordance with the stage of pregnancy and the condition of the foetus. For the sake of convenience, we distinguish — 1. Cases of early gesta- tion ; 2. Cases of advanced gestation (foetus living) ; 3. Cases of gesta- tion prolonged after the death of the foetus. 1. Cases of Early Gestation. — The indication for treatment in the early months varies with the conditions. If rupture has occurred, care should be employed to ascertain, if possible, whether the resulting hsemorrhage has taken place between the folds of the broad ligament, or, if intraperitoneal, whether the blood is free in the abdominal cavity, or is restricted to the pelvis by old adhesions. Circumscribed effusions of blood due to ruptured tubes do not, as a rule, threaten life, and disappear with time and with little other treatment than rest in the recumbent posture. If the outpouring of blood has taken place primarily into the ab- dominal cavity, or as a secondary occurrence after the giving way of the first barriers, laparotomy is unquestionably demanded. While it is not denied that even in these extreme cases the effused blood may be circumscribed by an adhesive inflammatory process, and that a few patients may recover with an expectant treatment, the waiting policy is * Hawley reported in the N. Y. Med. .Jour., June 16, 1888, a case where the diagnosis made previous to rupture was conftrmed by laparotomy. 344 THE PATHOLOGY OF PREGNANCY. a gamble with life. On the other hand, the opening of the abdomen for the purpose of removing blood and clots, and for the extirpation of the tube-sac has been the means, since Mr. Tait demonstrated the practicability of the operation, of saving multitudes of women from impending death. The operation is not, as a rule, difficult. It involves the separation of adhesions where these exist, the tying of the pedicle, and the removal of the ruptured sac. In the intraligamentous form it may be necessary to ligate the attached portion in sections. Where a pedicle can not be readily prepared, Veit recommends the tying of the broad ligaments at the two extremities of the sac before proceed- ing to ligate the base. Previous to closing the abdominal incision great care should be taken to insure the arrest of haemorrhage not only from the stump but from the separated adhesions. When the diagnosis is made previous to rupture the choice lies between laparotomy and the employment of measures to destroy the life of the embryo. In practice the decision is pretty certain to be governed by other than theoretical considerations. Thus an experi- enced operator, who possesses trained assistants and can command for his patient the surroundings which are needful for success, will be apt to select laparotomy. The risks have been proved to be small, and the patient is relieved from possible future troubles due to retention of the products of conception. But all men are not experts in pelvic surgery. The danger which threatens the life of the patient is often imminent, and assistance from afar is not always easy to obtain. Under these conditions the indication for treatment is plainly the adoption of measures to destroy the life of the foetus, and thus, by arresting the growth of the ovum, to diminish the chances of rupture and of haemor- rhage. The methods which have heretofore been employed to destroy the ovum are puncture of the sac, injections of morphia solutions, elytrot- omy, and the faradic current. Puncture of the Sac. — Puncture of the sac is usually easily effected by the introduction of an exploring trocar through either the vaginal or rectal wall. The operation is to be recommended on the score of simplicity, but has not been attended with very brilliant results. Re- coveries after puncture have been recorded by Greenhalgh, Tanner, Stoltz, Jacobi, Koeberle, and E. Martin (two cases). Fatal issues from septicaemia and peritonitis followed puncture in the hands of Eouth, J. Y. Simpson, A. Simpson, Martin, Braxton Hicks, Thomas (two cases), Conrad, Netzel, Hutchinson, John Scott, Gallard, and Depaul. Frankel * withdrew nearly three fifths of an ounce of am- niotic fluid from the sac without interrupting the course of preg- nancy. * FeXnkel, Zur Diagnostik und operative Behandlung der Tubenschwanger- schaft, Arch. f.

EXTRA-UTEfllNE PREGNANCY. 345 Injections of Solutions into the Sac, designed to destroy the Fcetus — This method was first suggested by Joulin.* He proposed injections of sulphate of atropia (one fifth of a grain dissolved in a few drops of water) into the sac by means of a long hypodermic syringe. His sug- gestion subsequently was successfully carried into effect in two cases by Friedreich,! of Heidelberg. The needle of the syringe, he advised, should be introduced into the sac through the abdominal or vaginal walls, a few drops of fluid should then be Avithdrawn, and its place supplied by the solution containing the poison selected. Friedreich employed by preference a fifth of a grain of morphia. The operation was repeated every second day, until the diminished size of the ovum afforded evidence that the result sought for had been accomplished. T'he operation seemed to produce but slight inflammatory disturbance, and the maternal system did not feel the influence of the narcotic. Eennert \ has since succeeded in destroying the life of the foetus in the fifth month of extra-uterine gestation by means of a single injec- tion containing about half a grain of morphia. The patient recov- ered after a protracted illness. Koeberle reported to the Gynaecologi- cal Section of the Eighth International Medical Congress at Copen- hagen a case of advanced abdominal pregnancy where the child was destroyed by morphia injections. The foetus and placenta were ab- sorbed. The recovery was complete. Six cases have been reported by Winckel, and one by Fournier. Of the eleven cases, three died. 2iie Faradic and Galvanic Currents. — The transmission of the faradic current through the ovum has proved a safe and efficient method for destroying the life of the foetus during the first three months of its existence. The application consists in passing one pole into the rectum to the site of the ovum, and pres'Sing the other upon a point in the abdominal wall situated two to three inches above Pou- part's ligament. The full force of the current of an ordinary one-cell battery should be employed for a period varying from five to ten min- utes. The treatment should be continued daily for one or two weeks, until the shrinkage of the tumor leaves no doubt as to the death of the fcetus. The successful employment of the faradic current in extra-uterine pregnancy we owe to Dr. J. G. Allen, who reported two cases of re- covery through its instrumentality in 187^. His first case occurred in 1869, the second in 1871. Previously, in 1859, Burci had succeeded in shriveling up the ovum, in a case of tubal pregnancy, with the * JouLix, Traite complet desaccouchements, \). 968. f CoHNSTEiN, Beitrag zur Schwangerschaft ausserhalb der Gebarmutter, Ai'ch. f.

In 1866 Dr. Braxton Hicks tried the faradic current, but abandoned it after the second application. Dr. Allen was apparently in no haste to report his triumphs, but appears to have mentioned them incidentally in the course of a discussion before the Obstetrical Society of Philadelphia. So little pains did he take re- garding his discovery that the subject was nearly forgotten, until a^ new success was reported by Drs. Levering and Landis, of the Starling Medical College, in 1877. Since then. Brothers* has collected fifty cases in which electricity was employed. In twenty-five cases, to which I can add a twenty-sixth from my own practice, and not included in Brothers's list, the health of -the patient was ascertained to be good at the end of periods varying from one to eight years. There were no evil results in any of the cases traceable to the elec- tricity. Of the four fatal ones, in that of Janvrin rupture of the tube had undoubtedly taken place before the galvanism was employed ; in that of Wylie the eight months' foetus was killed by injections of morphia into the sac after electricity had been discarded ; and in the cases of Duncan and Steavensen and Boulton and Steavensen electro- puncture was employed, Against the method, it lias been urged that the successes reported are in themselves evidences of an erroneous diagnosis, that the faradic or galvanic current endangers the integrity of the tube, and that the ovum, after its vitality has been destroyed, is liable to produce suppura- tion. But a 'priori deductions should not be allowed to outweigh the evidence of carefully conducted experiments. It should be borne in mind, however, that electricity. is only available in the first three months, and that no one in this country advocates electro-puncture. f Cases of Advanced Gestation. — After the third month it has now come to be regarded as a settled rule that the removal of the foetus, the placenta, and the investing membranes should be attempted as soon as the diagnosis has been made. If complete extirpation of the sac proves impracticable, it should be removed to the fullest extent possible, as its presence when left in situ is capable of leading to in- tractable sinuses and persistent suppuration. The older method of stitching the sac to the abdominal wall and leaving the placenta to come away spontaneously, fyrnished a certain number of favorable re- * A. Brothers, Subsequent Behavior of Cases of Extra-uterine Pregnancy treated by Electricity, American Jour. Obstet., vol. xxiii, No. 2, 1890. f Dr. Franklin H. Martin {vide Goelet's Archives of GyucTeeology, 1891, p. 100) has sought to show, by experiments on incubating hen's eggs, that the faradic cur- rent is relatively worthless as a feticide agent, and recommends the substitution in all cases of the galvanic current. If this should be established with regard to the human ovum, it must be confessed it would greatly weaken, if not destroy, the argu- ment in favor of electric treatment, since nearly all the reported successes have been obtained by faradism. EXTRA-UTERINE PREGNANCY. 347 suits after the death of the child and the arrest of the circulation had taken place. During the life of the child death from haemorrhage was the nearly uniform result. The conclusion drawn from this experience was to await the death of the foetus before operating, thus exposing the woman to the manifold dangei'S arising from the presence in the peri- toneal cavity of a growing ovum, or of a sac containing dead matter, often in a state of putrefaction. But with clearer anatomical views of extra-uterine pregnancy, it is getting more and more to be recognized that the treatment of that condition is subject to the ordinary rules of abdominal surgery. The difficulties encountered in the removal of the fetal sac are the result of excessive vascularity and extensive adhesions, but these obstacles to success have of late been found in many cases not to be insuperable. In the purely tubal form, where advanced gestation is reached without rupture, the uterine end forms a pedicle which permits the employment of the ligature en masse. In this category should be placed the case of Olshauseu, and probably that of Eastman. In an intraligamentous case, Breisky first stitched the sac to the abdominal wound and removed the foetus. He then removed the stitches, ligated the broad ligament on the side of the uterus, and separated the tumor, tying at the same time any large vessels found bleeding on the cut surface. By progressive ligation of the base from within outward toward the pelvic walls, the sac with the contained placenta was detached with but slight loss of blood. A portion of the sac which had grown into the meso-C£ecum was enucleated. Packing with iodo- form gauze was subsequently resorted to. Schauta * has recently reported a method in the intraligamentous form which promises important future results. The ovum and uterus apparently constituted a single growth. It was impossible to ligate between them. He succeeded, however, in applying a double ligature to a peritoneal fold, which formed the residue of the ligamentum infundibulo-pelvicum. After dividing between the ligatures he got underneath the peritonaeum, which he severed by a circular line to the right uterine cornu. The peritonaeum was then dissected away from the sac wall without noticeable haBmorrhage, and the six months' ovum was enucleated entire. Upon detaching the ovum from the uterine wall there was considerable bleeding, requiring the provisional employment of compression and the subsequent use of the suture. The peritoneal sac was then attached to the wound, and drained by Mikulicz's method. In these four cases, all of which ended in recovery, success was due to the complete extirpation of the sac. Werthf reported in 1889, to * Schauta, Beitrage zur Casuistik, Prognose und Therapie der Extrauterin- sehwangerschaft, Prag, 1891. f Werth, Behandlung der Extrauterinschwangerschaft, Verhandlungen der 348 THE PATHOLOGY OF PREGNANCY. the Third Congress of the German Gynaecological Society, nine opera- tions between 1887 and 1889. The case of Schauta increases the list to ten. Of these, eight recovered and two died. It was not possible to remove the entire sac in every case, but even partial extirpation, with employment of ligatures to the placental vessels and removal of the. placenta, has been found to lessen the risks of the operation and to shorten the period of convalescence. After the death of the foetus the same principles hold good so long as the sac contents have not been infected. After putrefaction or pus formation has set in the older method of stitching the sac to the abdominal incision previous to opening it is still the best. After the removal of the foetus the placenta should be left to separate spon- taneously. While the detachment is taking place, it has been found that a mixture of tannin and salicylic acid strewed upon the inner surface of the sac is useful as a styptic and a disinfectant.

Fatal cases occurred in the practice of Prochownik and L. Braun. OBSTETEIO SUEGEET. CHAPTER XVIII. THE INDUCTION OF PREMATURE LABOR. Induction of premature labor. — Indications. — Contracted pelvis. — Habitual death of foetus. — Diseases which imperil the life of the mother. — Operation. — Cathe- terisatio uteri. — Intra-uterine injections. — Rupture of membranes. — Mechanical dilatation of cervix. — Vaginal douches. — Tampon. — Choice of methods. — Care of the child. — Artificial abortion. The induction of premature labor is indicated in cases in which the continuance of pregnancy, or delivery at full term, is associated with risks to mother or child, or to both, which may be diminished by bringing pregnancy to a close at an early period after the foetus is prepared for extra-uterine existence. The time at which the latter begins is usually placed at the twenty-ninth week. As, however, the preservation of the child at so early a date is an exceptional occurrence, and as a large proportion of those which by tender care are made to survive the first danger of immaturity perish in infancy, commonly falling a prey to hydrocephalus or to intestinal derangements, the in- terests of the child call for the postponement of the operation as long as practicable. Where the choice lies with the physician, the provo- cation of labor is usually deferred until the thirty-third or thirty- fourth week. The principal indications are : 1. Moderate Degrees of Pelvic Contraction. — In flattened pelves measuring from two and three fourths to three and one fourth inches, and in equally contracted pelves under three and one half inches, the passage of a full-term child is not impossible, though usually diflScult and dangerous. By inducing premature labor, however, owing to the smaller size of the foetus, and especially to the increased compressibility of the fetal head, we are enabled to diminish the mechanical obstacles to delivery, and thus to improve the prognosis for both mother and child. To the mother the advantage from the operation is in all cases decided, while to the child not much is gained in the extreme degrees of contraction. The time at which gestation should be interrupted depends upon the size of the pelvis and our estimate of the size of the fetal head. The distance from the lower border of the symphysis to the promon- 350 OBSTETRIC SURGERY, tory should be accurately measured, and the side walls of the pelvis carefully explored. Schroeder's measurements show that the bipari- etal diameter of the head is, between the twenty-eighth and thirty-sec- ond week, about three and one fourth inches ; between the thirty-second and thirty-sixth week, nearly three and a half inches ; and that after the thirty-sixth week the increase is insignificant.* One of the most important questions to be decided in reference to the induction of labor is the period to which gestation has advanced. But this, in the absence of well-defined signs, it is easy to miscalculate. Physicians have been misled by the large size of the uterus in twin pregnancies and hydramnion into provoking labor before extra-uterine existence was possible. Ahlfeld has shown that the long axis of tlie foetus, when flexed in utero, is almost exactly one half its entire length in an extended posi- tion. He proposes measuring the former with a Baudelocque pelvim- eter, by placing one extremity per vaginam upon the child's head, and the other upon a point in the abdominal walls over the fundus of the uterus at which the breech of the child is felt. Very nearly the same results were obtained by measuring from the upper border of the symphysis in place of passing the lower branch through the genital canal. The following arrangement, based upon his tables, places be- fore us in a practical way the result of his investigations, so far as they apply to the questions involved in the induction of premature labor : f 2. HaUtual Death of the Foetus. — It has been proposed that, when in successive pregnancies the foetus perishes in utero during the latter weeks of gestation, labor should be induced after the period of viability has been reached, but before the time at which, according to previous experience, the fatal ending was to be expected. This plan of treat- ment does not apply to cases where death is due to syphilis, as a better * ScHROEDER, Lehrbuch der Geburtshiilfe, 4te Aufl., p. 235. It is to be remem- bered that the biparietal diameter is capable of a considerable degree of compres- sion, and that it is usually the bitemporal rather than biparietal diameter which has to pass the narrowest diameter of the pelvis. f The arrangement is modified from one furnished by Stahl (Geburtshiilfliche Operationslehre, p. 47). Owing to individual differences in the length of the foetus at the same period of gestation, a considerable source of error inheres to the Ahlfeld method of computation. It is, however, much less than those to which estimates based upon the size of the uterus are subject. Axis of foetus. Length of foetus. Biparietal diameter.

Little benefit, too, would be derived from pre- mature labor where the death is due to organic diseases of the fcetus. But where death is the result of inanition, dependent upon maternal anaemia, degenerative changes or faulty development of the placenta, or alterations of the umbilical cord, the operation is fully justifiable. With the difficulty, however, of making the diagnosis and fixing the time when labor should be induced, there have been but few cases in which the procedure has furnished favorable results. 3. Diseases whicli imperil the Life of the Mother. — In these cases the operation is primarily performed in the interests of the mother, and is indicated, therefore, even when the child is known to have per- ished. Sometimes, however, premature labor becomes a means of sav- ing tlie life of the child, which shares the dangers that threaten the maternal existence. In this category belong especially chronic affec- tions of the heart and of the respiratory organs ; enormous distention of the abdomen from multiple pregnancy, hydramnion, tumors, and ascites, which occasion extreme dyspnoea ; pernicious augemia ; uncon- trollable vomiting ; haemorrhages from placenta praevia ; chorea ; con- vulsions ; and nephritis, associated with excessive oedema. In each case, however, it is incumbent to carefully consider whether the special condition is rendered more threatening by the existence of pregnancy, and to weigh the question as to how far, for the time being, the dan- gers are likely to be increased by the progress of labor. Stehberger has proposed extending this indication to cases where the preservation of the mother's life is hopeless, but in which prema- ture delivery affords a chance of saving the life of the child.* Operation. A great number of methods have been proposed with a view to pro- voke labor prematurely. Most of them, however, such as the adminis- tration of ergot, of quinine, or of jaborandi, the stimulation of the va- gina with carbonic acid, frictions of the breasts, and the like, do not require anything more than cursory mention. The following proced- ures alone possess any special claims to favor ; Catheterization of the Uterus. — This method consists in the intro- duction of a catheter, or, better still, an elastic bougie, between the mem- branes and the walls of the uterus, and leaving the instrument in situ until active labor sets in. In performing the operation it is a good plan to place the patient in a recumbent posture upon a hard table, with the hips brought near the edge, and the thighs well fixed upon the body. After preliminary vaginal disinfection, two fingers guide the point of the bougie into the cervix, the index-finger, passed to the os in- * Stehberger, Lex regia und kiinstliche Frlihgeburt, Arch. f. Gynaek., Bd. i, p. 465. 352 OBSTETRIC SURGERY. ternum, then follows the instrument, and as it enters the uterus directs it to one side to prevent it from rupturing the membranes. In the case of primipar^, preliminary dilatation of the cervix may be secured, if necessary, by the use of a sponge-tent or of the vaginal douche. The bongie should be pushed slowly upward with the disengaged hand and allowed to follow its own course, between the membranes and the uterus. To prevent the instrument from slipping down, two inches of the extremity may be left outside the cervix to find support against the vaginal wall. A retentive tampon is rarely necessary. The method is tolerably certain. In favorable cases labor follows its employment in the course of a few hours. As a rule, the response is more prompt in multipara? than in primiparae. Sometimes, however, no action is set up during the first forty-eight hours, or the pains ex- cited are of a cramp-like character. In either case it is well to resort to other additional measures. Outside of unwholesome hospitals, the use of the catheter or bougie to excite labor is not associated with any peculiar risks. The danger of detaching the placenta is not im- minent, if the instrument be introduced slowly, as, owing to its elas- ticity, the bougie tends to make its way around the placental margin. In maternity hospitals, however, it may serve as a point of entry for miasmatic poisons, and thus be followed by local irritation and puer- peral septic affections. Because of this danger the solid bougie is pref- erable to the hollow catheter. In all cases only a perfectly clean and new instrument should be used. Injections between the Uterus and Ovum.— Cohen, of Hamburg, proposed in 1848 the separation of the membranes by injecting tar- water through a long-nozzled syringe made to penetrate about two inches within the uterine cavity. The nozzle was furnished with a rounded extremity, and with openings upon the side. He recommended that the injection should be continued until a distinct feeling of dis- tention was experienced by the patient, which sometimes required the employment of nearly a quart of the fluid (720 grammes).* This plan has since been modified by the substitution of an elastic catheter for the metallic tube, and by the injection of a few ounces of simple warm water (98° Fahr.) in place of the aqua picea. In case of failure with a single injection, it has been recommended to repeat the proced- ure. Professor Lazarewitch has demonstrated that the nearer the irri- tation is carried to the fundus the more certain and speedy the result. He therefore employs a syringe with a central opening, and passes it as near to the fundus as possible, f When efficiently performed, the method possesses the advantage of rapidly exciting uterine labor-pains. Kiinne reports fifteen cases in which he resorted to it with complete success. He cautions against * Cohen, Neiie Ztschr. f. Geburtsk., Bd. xxi, p. 116. f Lazarewitch, Trans, of the Obstet. Soc. of London, 1868. THE INDUCTION OF PREMATURE LABOR. 353 using force in injecting, and recommends, as a means of avoiding the passage of air into veins, the withdrawal of the catheter, and its re- introduction, in case a haemorrhage should betoken that the placenta had been impinged upon. Others have employed the method many times witli entire impunity. Still, cases of sudden death have occurred during its use, which have been referred to shoclv, to air getting into the uterine sinuses, and to rupture of the uterus. While, perhaps, the general results from uterine injections have not been less satisfac- tory than from the employment of other measures for inducing j)re- mature labor, the suddenness of death in the fatal cases has had a deter- rent effect ui)on its extended employment. Rupture of the Membranes. — This is the oldest of all the methods now in use. It is best performed by means of a simple apparatus de- vised by the Freiherr Braun von Fernwald, consisting of a goose-quill sharpened like a pen and nicked upon its convex surface for the pas- sage of a uterine sound. Thus mounted, with its point guarded by the sound, it can be introduced, without risk to the maternal tissues, -through the cervix to the ovum. Then, by simply pushing the quill upward, the point is made to clear the sound and effect the puncture of the membranes. The method is certain, though not always speedy in its action. It is open to the objections which hold good in all cases of premature discharge of the amniotic fluid. Hopkins recommended, as a mode to provide for the gradual escape of the liquor amnii, tap- ping the membranes with a sound at a distance from the os internum. Rokitansky has shown, from the statistics of Braun's clinic, that in hospital practice puncture of the membranes is the safest means of inducing premature labor, diminishing as it does the chances of infec- tion, which is the chief source of danger in all the measures where the irritation is applied directly to the inner surface of the uterus. Though in private practice I have never from choice selected this method, I have witnessed many cases in which the membranes have ruptured accidentally, and yet have failed to notice, either in the case of the mother or child, the serious consequences which theory would lead us to apprehend. It is not adapted for the higher degrees of pelvic con- traction or for cases Avhere speedy delivery is desirable. Mechanical Dilatation of the Cervix. — The dilatation of the cervix with sponge-tents or laminaria is rarely resorted to, except as prepara- tory to other measures. While the expansion of the tent softens the cervix and excites uterine contraction, the effect is frequently tran- sient. To be sure, the action may be kept up by a succession of tents gradually increasing in size, but such a plan denudes the cervix of its epitlielium, and is apt to lead to septic infection. The Barnes dilator is a most efficient aid in cases of induced labor. It should be surgically clean, and before its introduction both vagina and cervix should be thoroughly disinfected. I have found it conven- 2.3 354 * OBSTETRIC SURGERY. lent to seize it, properly folded, with a pair of dressing forceps, by means of which it can be passed into the cervical canal. I then withdraw the forceps, and push the dilator upward with two fingers. The dilator is, as Barnes has termed it, a water-bag. It should never be distended with air, as rupture of the bag in that case might be speedily followed by the death of the patient. As for the introduction of the smallest- sized bag the cervix requires to be sufficiently expanded to permit the passage of at least two fingers, it is useful chiefly as an adjuvant to other plans of treatment. At first the dilatation should only be carried to the extent necessary to render the cervix tense. When labor has fairly begun, the fluid pressure of the dilator upon the cervix serves to strengthen the uterine action. When left in situ, the instrument in- sures the development of good pains. It should, however, be removed from time to time, if not forcibly expelled into the vagina, and carbol- ized injections should be employed to prevent infection. So soon as the physiological softening of the cervix which results from labor has been effected, rapid dilatation can be advantageously employed. When the cervix is rigid, the rubber bag is only useful as a reflex exciter of pains. To be sure, the rigid cervix can be forcibly dilated to almost any extent by hydrostatic pressure, but, as a rule, it closes down to its original dimensions so soon as the pressure is removed. In rare cases forcible dilatation may lead to cervical laceration. Tarnier has devised a bag which can be passed upward through the cervix and distended in the lower uterine segment. It serves to par- tially detach -the membranes, and excites by its presence active uterine efforts. Its liability to rupture is the most serious objection to its em- ployment. The Vaginal Douche. — The vaginal douche was introduced into practice by Kiwisch, in 184G. It consists in directing a stream of tepid Avater with considerable force directly against the cervix. The stream may either be furnished by a Davidson's syringCj or a continuous cur- rent from a tube connecting with a vessel placed at an elevation above the patient may be used. The latter is the safer method. The large- sized fountain-syringe, made to hold a gallon of water, is a very con- venient apparatus. The duration of each injection should be from ten to fifteen minutes. At the outset, three douches in the twenty-four hours suffice. Subsequently the frequency and duration should de- pend upon the degree of action excited and the urgency which exists for bringing labor to a close. Twelve are about the average nuniber of injections required. In pressing cases they have been repeated as often as once in three to four hours. The temperature of the water employed should be about 106° Fahr, In using the douche the patient should be placed across the bed, and an India-rubber sheet should be so arranged under the hips as to convey the water as it escapes from the vulva into a vessel beneath. THE INDUCTION OP PREMATURE LABOR. 355 Every care should be taken to avoid the introduction of air into the vagina, and at the beginning of each douche precautions should be adopted to facilitate the escape of the fluid. The forcible pressure of the stream has been known to drive air contained in the vagina into the cervix. The same accident has followed imperfection in the valves of the syringe. The douche acts by the M^armth of the water, by stimulation of the lower uterine segment, and by dilatation of the vagina. After the douche has' been continued for a time, the latter is sometimes distended so as to be nearly in contact with the pelvic walls. The vaginal douche as a means of inducing labor has of late years fallen somewhat into disrepute. Its chief recommendation was the supposed harmlessness of the procedure — a precious quality, to which in reality it appears, however, to possess little claim. Numerous cases have been reported where death has followed the accidental introduc- tion of air, and sharp peritoneal symptoms, according to Kleinwiich- ter,* have been known to result from the excessive distention of the vagina. The dangers referable to the latter cause increase with the repetitions of the douche. It is likewise claimed that its repetition tends to lessen the efficiency of the uterine contractions. At present its employment is generally restricted to the preliminary dilatation of the OS, or to the sustaining of the action of other measures. The Vaginal Tampon. ^ — Braun introduced an India-rubber bag, fur- nished with a tube and a metal stop-cock, which, under the name of the col2Jeiiryntei\ still plays a considerable role in obstetrical practice in Germany. When filled with water in the vagina, it formed a pain- ful and rather uncertain mode of inducing labor. It is now rarely employed except in haemorrhage, and where it is desired to prevent premature rupture of the membranes. Care should be taken to only moderately distend the vagina, and not to continue the pressure for any lengthened period of time. Galvanization. — Bayer f urges the constant current as an available means of exciting labor-pains. He recommends placing the negative pole of a suitably constructed electrode in the cervix, and the positive pole upon the abdomen near the fundus. Ten to sixteen elements should be used for a j)eriod varying from ten to twenty minutes. The advantages claimed for galvanism are, that it excites true pains, that it does not produce strictures, that it causes the cervix to soften and dilate naturally, and that by its use the dangers of infection are less- ened. The chief drawback consists in the necessity for frequent repetitions of the procedure before labor is brought to a close. Thus, in the six cases where it was used by him, from two to thirteen appli- * Kleinwachter, Prager Vierteljahrsschrift, 1872, Heft i, p. 56. f Bayer, Ueber die Bedeutung der Electricitat in der Geburtsh. und Gynaek., vol. xi, p. 89. 356 OBSTETRIC SURGERY. cations were made, and the time from tlie first application to the birth of the child varied from two to eleven days. As the effect of the first application is to soften the cervix and render it dilatable, galvanism may in the future find its place as a substitute for tents, or the vaginal douche, in the preparation of the lower uterine segment for the em- ployment of accelerative measures. Choice of Methods. — From the foregoing it will be seen that no one of the different proceedings mentioned is entirely free from objection. Aside, however, from infection — a danger more especially dreaded in maternity hospitals — and the avoidable accident of driving air into the veins, the most serious difficulties against which we have to contend arise from the tardy dilatation of the os and the prolongation of labor. Any of the methods are good if only they act speedily. It is advisable, therefore, in practice to follow the excellent advice of Dr. Barnes, and divide the induction of premature labor into two stages, in the first of which provocative, and in the second of which accelerative, meas- ures should be adopted. In the former category should be placed the dilatation of the cervix with tents, the vaginal douche, and the cathe- terization of the uterus ; in the latter, dilatation of the cervix with the rubber bags, rapture of the membranes, and, in case of delay, delivery with forceps or by version. The plan I have generally followed consists in beginning in the aft- ernoon with the vaginal douche, and following with the introduction of a solid bougie, to be left in the uterus overnight. In many cases labor is excited in the course of a few hours. In the morning, if the process is delayed, the vaginal douche is repeated. There are few cases in which, toward the end of the twenty-four hours, the cervix is not found softened and well lubricated with mucus. The dilators should then be employed, the operator taking his time, as permanent dilata- tion is the object sought after. If the membranes come down well, the dilator may be removed and the progress of the case left to Xa- turei ' Often it is advisable to adopt the plan of Dr. Barnes, rupturing the membranes when the cervix will admit three or four fingers, and then dilating with the large-sized bag until the uterus is opened fully for the passage of the child. Finally, according to the conditions present, the physician may either await the termination of the labor, or deliver by version or by lightly constructed forceps. Care of the Child. — Premature infants possess slight powers of re- sisting external agencies. The customary baths should possess a tem- perature of 100° Fahr., or very nearly that of the amniotic fluid. The chances of raising premature infants are greatly enhanced by feeding them ^v^ith mother's milk. The artificial maintenance of the body-heat is essential to the preservation of life in the early period of extra-uter- ine existence. In a rude way this may be accomplished by placing the child in warm cotton near the fire. Before the thirtv-second week THE INDUCTION OF PREMATURE LABOR. 357 the result in such cases depends almost entirely upon the unremitting watchfulness and zeal of a devoted mother or nurse. Much better results are, however, obtainable through the agency of the contrivances of Crede and of Tarnier. Crede's * apparatus possesses the advantage of cheapness and sim- plicity.

A stop-cock below, at the opposite end, permits the water to be withdrawn at will. In this vessel the child is placed, enveloped in fine cotton or soft flannel. The coverings should reach to the brim of the vessel, the face of the child alone remaining exposed. Every four hours the space between the walls is to be filled with water heated to 122° Fahr. When the water is first introduced, the tempera- ture within the tub is about 1071°. In the last two hours it sinks to about 99-|-°. In extreme degrees of prematurity, a more equable tem- perature may be maintained by partially refilling every hour or every half-hour. The child is to be disturbed as little as possible. It should be removed only to be bathed and to be placed to the breast. The napkins should be changed, as far as possible, within the vessel.

The total number of children thus treated amounted to six hundred and seventy-eight. The weight of these children, with few exceptions, was less than five and a quarter pounds. The tota'l mortality was eighteen per cent. Of twenty-four children weighing between two and three pounds, twenty died; of one hun- dred and fifteen children weighing between three and four pounds, forty-two died; of four hundred and seventy-six children weighing between four and five pounds, fifty-four died; while of fifty-two children weighing between five and six pounds (seventeen twins), but one died. The incubator of Tarnier was first used at the Maternite, in 1881, for the rearing of prematurely born children. It consists of a wooden box with walls 0-10 to 0-12 centimetre thick, filled in with sawdust to prevent loss of heat. A central partition divides the box into two compartments, the one for hot water, the other for the infant's cradle. A metal case, of a capacity of about seventy-one litres, fits into the lower compartment, leaving a space of two to three centimetres between its walls and those of the box for the free circulation of air from below upward. The capacity of the upper com- partment is about eighty-six cubic centimetres ; there is free circulation of air be- tween it and the lower com- partment, and it is in com- munication with the outer air by means of two open- ings — the one, on its iipper surface, shut in by a double plate of glass, the other, laterally, opening like a door, and allowing exit to the cradle. In each corner of this upper compartment is a hole for the escaj^e of the heated air from below. To the lower com- partment, containing the hot water, is attached a thermo-siphon by an upper and a lower tube. When the lamp under this siphon is lighted, the heated water fiows through the upper tube into the chamber, dis- placing an equal amount of water which flows back to the siphon. Thus a current is established, the temperature of which can be raised to the desired point. In cold weather it has been found necessary to light the lamp three times daily, allowing it to burn each time about two hours. The lamp should be extinguished when the tempera- ture in the upper compartment is about two degrees above the heat Fig. 143.— Section of hospital inc-uhator. (Tarnier.) THE INDUCTION OF PREMATURE LABOR. 359 desired. The registering thermometer may be laid alongside the infant.* In general, a mean temiierature of 86" Fahr. is sufficient, but 90° is borne without harm. The children should be clothed in the usual manner. The napkins should be changed five to six times daily. A daily bath should be given. Children sufficiently developed to suckle should be placed to the breast. Those too feeble to nurse are fed in Paris upon asses' milk. The result of two years' trial of the incubator at the Paris Maternite Auvard reports as follows : Of ninety-three healthy premature children, thirty-one died ; of fifty-eight premature children with complicating diseases, fifteen died. In comparing these results, however, with those reported by Crede, it is necessary to note that at the Maternite, in Tarnier's service, only children weighing four pounds and less were placed in the incubator, while the limit in the Leipsic Maternity was in general five and a quarter pounds. Aktificial Abortion. Artificial abortion is Justifiable whenever it offers the only hope of saving the life of the mother. The morality of this general proposi- tion is unquestioned. It is not, however, by any means easy to deter- mine in a specified case whether the conditions which render the in- duction of abortion a duty really exist. The principal recognized causes for the operation which admit of little dispute are : 1. Incarceration of the j^rolapsed or retroflexed uterus when the dislocated organ can not be replaced. 2. Diseases of pregnancy which immediately imperil life, and which have been vainly combated by all the resources at our disposal. Qf these diseases the most prominent is uncontrollable vomiting. Exceptionally, the indi- cation may arise in affections of the heart, lungs, and kidneys, where the symptoms are acute and peculiarly threatening. The justifiability of abortion is, however, by no means so clear when the danger to the mother first arises after labor has actually begun. This is especially the case in extreme degrees of pelvic con- traction, or where the presence of large tumors renders the parturient canal impassable, as in these cases, by means of the Ca?sarean section, there is always a probability of saving the life of the child, with a fair prospect of preserving the existence of the mother. It is considered right, under such circumstances, after a dispassionate and colorless statement of the facts, to leave the decision to the mother and the friends more immediately interested. When the operation is *per- formed for contracted pelvis, the following figures will show at how late a period it may be undertaken : * Auvard, De la couveuse pour enfants, Arch, de Tocologie, October, 1883, p. 577.

With less than an inch the difficulties of inducing abortion increase to such a degree as to make the operation rarely advisable, or indeed even practicable.* The induction of abortion is accomplished by puncturing the mem- branes with a uterine sound, or by dilatation of the cervix with a sponge- or a tupelo-tent. In the early months dilatation by means of a tent possesses the advantage of promoting the expulsion of the ovum entire. In the sixth and seventh months the same means are available that have been described in connection with the induction of prema- ture labor. Preparation of Aseptic >Spo?iges for Obstetrical Purposes.— The sponges em- ployed should be of the finest quality. They should be pounded with a wooden mallet until the cretaceous particles can no longer be felt, then washed for ten minutes in a two-per-cent solution of permanganate of potash, and washed and kneaded thereafter in a two-per-cent solution of bioxalate of potash, till they become of a yellowish-white color, and no more sediment remains in the solution. To remove the oxalic acid, they should be washed in distilled water until no reaction is produced with lime-water. The sponges, in this way freed of inorganic matter, should be allowed to soak two days in a five-per-cent solution of carbolic acid. The carbolized sponges are to be pressed out two or three times in a ten-per-cent solution of gum arable. A knitting needle is passed into the sponge and a carbolized thread employed to compress it into a cylindrical shape, care being taken not to give the sponge a spiral turn in the winding. Then withdraw the needle, wrap in tissue paper, and leave the sponge to dry. The drying usually requires three or four days. Finally, remove the silk, file away rough portions, and place in metal box for future use. (Method of Jungbluth, vide Zur Behandlung der Placenta Praevia, Volkmaunsche Sammlung, No. 235.) As to the choice of time when the operation should be performed, opinions differ. Some prefer the first two months, on account of the small size of the ovum and the slight development of the fetal tufts at the decidua serotina. Most physicians wait till the first three or four months have expired, as the diagnosis of pregnancy is then cer- tain, the execution of the operation easy, and the detachment and ex- pulsion of the fetal appendages more complete. * De Soyre, Dans quels cas este-il indique de provoquer Favortement ?

History. — The forceps, it is well known, is the invention of the Chaniberlens.* It was held by them as a family secret, and utilized purely as a means of gain. In the early part of the year 1670, Hugh Chamberlen, who enjoyed a great reputation as an accoucheur, went to Paris in the hope of finding a purchaser for it. Mauriceau, to test the value of Chamberlen's pretenses, suggested that the latter should attempt the delivery of a woman with extreme contraction of the pel- vis, upon whom he had previously decided to perform the Cgesarean section. Chamberlen declared that nothing could be easier, and at once, in a private room, set about the task. After three hours of vain effort he was obliged to acknowledge his defeat. The woman died ; the nego- tiations for the sale were dropped, and Chamberlen returned with his secret unrevealed to England. In 1672 Chamberlen published a trans- lation of Mauriceau's work upoii midwifery, in the preface of which he states : " My father, brothers, and myself (though none else in Ettrope, as I know) have, by God's blessing and our own industry, attained to and long practiced a way to deliver women in this case without any prejudice to them or their infants, though all others (being obliged, for want of such an expedient, to use the common way) do or must en- danger, if not destroy, one or both with hooks." In 1688 Hugh Cham- berlen went to Amsterdam and sold his secret to Roonhuysen for a large sum, who in turn disposed of it to Ruyscli and others; and, as late as 1746 it was the rule of the Medico-pharmaceutical College at Amster- dam that no one should practice midwifery without first obtaining the secret measure, which was imparted by their examining body for a heavy money consideration. In 1753 Jacob de Vischer and Hugo van de Poll, who had acquired the secret from the daughter of a former possessor, made it public property ; but the instrument turned out to be the sin- gle-bladed vectis. Whatever doubts, however, this exposure may have * Dr. J. H. AvELiNG, in an essay entitled The Chamberlens and the Midwifery Forceps, London, 1883, concludes that the inventor proper of the forceps was Peter Chamberlen the elder, who was taken by his father, a Huguenot fugitive, from Paris to London in 1569. Dr. Peter Chamberlen, who purchased Mortimer Hall, in Woodham, was the son of Peter Chamberlen the younger, a brother of the inventoi-. Dr. Peter Chamberlen's son, Hugh Chamberlen.

Fig. 144.— Forceps of Cham- berlen. cast upon the nature of the Chamberlen secret were set at rest, in 1815, by the discovery, in a former residence of the family in Woodhara, in Essex, of a chest containing, besides letters and a variety of patterns of the vectis, a number of pairs of forceps, fenes- trated, without a pelvic but with an excellent cephalic curve. Moreover, Chapman, in a short treatise upon midwifery, published by him in 1733, stated that "the secret men- tioned by Dr. Chamberlen was the use of forceps, now well known to the principal men of the profession both in town and country." And two years later, in a second edition of his work, he published an engraving of the instru- II J ~~\\ ment, which became known as Chapman's for- I IjlUJj I ceps, though it did not differ from the one used by the Chamberlens. Since Chapman's publication the modifica- tions made in the forceps by obstetric prac- titioners have been exceedingly numerous. Indeed, nearly every man widely engaged in midwifery practice finds it convenient to possess his own forceps. With few exceptions, however, the various patterns described by authors do not differ materially as regards essential principles, but have each some peculiarity of construction which fits them to supplement a personal defect of the contriver, or to meet some special indication. The forceps is by no means a perfect instrument. It is im- possible to construct it in such a way as to cover every need. In consulting practice, it is con- venient to possess a number of forceps for dif- ferent emergencies. A good pair for general use is necessarily a compromise between conflicting aims, and requires, for successful use, experience and intelligence to correct its deficiencies. In selecting forceps it is well to bear the fol- lowing points in mind : We have first to distin- guish between the long and the short forceps. Short Forceps.— The original instrument of the Chamberlens furnishes the type of the short variety. By referring to Fig. 144, it will be seen that the Chamberlen forceps consisted of two levers, made to cross each other like a pair of scissors, with short handles, and blades diverging just beyond the point of articulation. The blades were fenestrated, to lighten the instrument and to enable them to seize the head with greater secur- FlG. 145. -Forceps of Smel- lie. FORCEPS. 363 ity. They were furnished witli a cranial curve, as has been stated, but were straight when viewed in profile. Though somewhat rude in appearance, they were capable of rendering good service when the head had once entered the pelvic cavity. Smellie, in place of the mortise lock of the Chamberlen forceps, which required to be secured by tape or cord, invented the easily adjusted English lock, and co^■- ered the handles with wood and a durable coat of leather. The han- dles were five and a half inches in length, and the blades six inches. Short forceps, modified somewhat from the Smellie pattern, are used by some prac- titioners at the pres- ent day. It has been thought an advantage that they can be con- cealed in the pocket, and slipped over the child's head without the knowledge of the patient or of the as«- sistants. Smellie laid great stress upon this point, and says : " As women are commonly frightened at the very name of an instrument, it is advisable to con- ceal them as much as possible until the char- acter of the ojDerator is fully established." In these enlightened days, however, secrecy is no longer advisable. Indeed, the forceps ought never to be used without such exposure of the vulva as will enable the operator to exercise every precaution for the preservation of the perineum. Long Forceps.— Smellie tells us he found, in pelves with jutting-in of the sacrum, that he could not push the handles far enough back- ward to include between the blades the bulky part of the head, which lay above the pubes. He therefore, to remedy this inconvenience, contrived a longer pair, curved on one side and convex on the other. Thus, at an early period the necessity for long forceps was experienced Fig. 146.— Levret's forceps. 864 OBSTETRIC SURGERY, Smellie was deeply impressed, however, with the dangers of high for- ceps operations, and sought to diminish the risks incidental to them by making the handles short, to free himself, as he said, from the temptation of using too great force. Levret, on the contrary, contemporaneously with Smellie, converted the forceps of Chapman into a powerful tractor and compressor. He retained the iron handles, but roughened the surfaces, and made them slightly convex, to adapt them to the palms of the hand. The articu- lation was effected by means of a pivot and a mortise. The chief pecul- iarities, however, consisted in the weight and the length of the instru- ment and in the extent of the pelvic curve. So far from these features proving objectionable, they have been substantially retained in mod- ern French instruments. The forceps of Smellie and Levret are the two type-forms from which are derived the great number of the models in vogue at the present day. The Naegele forceps, exten- sively used in Germany, in its main features resembles the in- strument of Smellie. It is, how- ever, two inches longer, and there is less disproportion between the length of the handles and the blades. The upper part of the handles is furnished with trans- verse shoulders, hollowed out for the index and middle fingers of the hand which exerts the trac- tion force. The lock is that of Bruninghausen, and consists of a pivot, surmounted by a flat button, which fits into a notch upon the opposing blade. The Simpson forceps possesses a relatively short handle, with trans- verse shoulders, and indentations for the fingers of the under hand. The English lock is improved by the addition of knees or projections to diminish its mobility. The cephalic curve, in place of starting at the lock, is carried away two and three eighths inches by straight, parallel shanks, an arrangement which makes it possible to lock the instrument outside the vulva even when applied to the head at the brim, and which enables the operator to bring the head to the floor of the pelvis without placing the vulva upon the stretch. The pelvic curve does not exceed one inch and a half. I have been in the habit of recommending this forceps to my classes of medical students, on A B C FiG. 147.— Naegele's forceps.

It is, however, defective in compressive power, when such action is necessary.* The forceps of Hodge, of Wallace, and of White are extensively used in this country. Like those of French make, they have metal handles, and a lock composed of a movable pivot, which slips into a notch at the moment of adjustment. They are, however, much lighter and of more graceful outline. The shanks are long and super- imposed. The blades are provided with wide fenestra?, through which Fig. 149.— Hodge's forceps. the parietal bosses are intended to project. I have tried each of these instruments, and, thougli I cling to Simpson's forceps from habit, have found them extremely serviceable. Finally, in choosing forceps, it is well to remember that, if there are none which are absolutely perfect, there are few which are really poor. Objectionable features are very short handles and thin, spi'ingy blades with sharp cutting edges. A good pair of long forceps renders the possession of short forceps a superfluous luxury. Action of the Forceps. — The forceps is primarily and essentially a tractor. When properly adjusted, it serves as a handle by means of which the head can be withdrawn from the parturient canal. Many excellent operators are in the habit of combining with direct traction * The instrument-makers of this city are accustomed to make for me an instru- ment exactly copied from a pair of forceps hrovightby nie fiom Edinburj^^h in 1865. Many of the forceps bearing? Simpson's name in this country have only a faint re- semblance to the oii'r'''VT position. Descent of forehead beneath pubic arch completed. Elevation of liaiidle of forceps to aid the rotation of the occiput over the perinseum (Fara- boeuf and Varnier.) ^ If the sagittal suture occupies an oblique diameter, the forceps should be applied in the opposite oblique diameter. As the liead de- FORCEPS. 381 scends, the occiput should be turned iuto the hollow of the sacrum. At first, tractions should be made directly downward, until the fore- head has passed under the pubic arch and the anterior fontanelle makes its appearance at the vulva ; then, by raising the handles, the small fontanelle should be brought forward to the commissure, and, finally, as the vertex emerges from the vulva, the handles should be slowly depressed, to aid the movement of extension by which the delivery of the face and chin beneath the pubic arch is accom- plished. Forceps in Face Presentations. — When the face is deep in the pelvis and the chin has rotated to the front, forceps applications are easy, and do not differ materially from those in vertex presentation, except that care should be taken to direct the blades far enough backward to se- curely seize the occipital extremity of the child's head. Tractions should be made in a horizontal direction until the chin has been brought well under the symphysis pubis, when the handles should be raised to lift the cranial vault over the perinseum. In oblique mento- anterior positions, Spiegelberg advises introducing first the blade cor- responding to the chin (posterior blade), as, in adjusting the second blade and locking the forceps, spontaneous rotation usually takes jjlace. In deep transverse positions, forceps operations should be deferred as long as possible, as tardy rotation of the chin to the front is a physio- logical peculiarity in face presentations. The forceps should be ap- plied in an oblique diameter, with the concavity of the blades directed to the side of the chin. Chin right, introduce the right blade pos- teriorly, and bring the left blade forward to the left tuberculum ilio- pubicum. An effort should then be made to rotate the chin to the front. If the attemj)t prove successful, the forceps should be un- locked, and the blades readjusted to the lateral surfaces of the head. Tractions when the face is transverse should not be attempted. The wide separation of the blades makes it necessary to compress the han- dles firmly to prevent slipping. When this is done, pressure upon the neck and thorax is unavoidable, so that extraction without sacrificing the life of the child is hardly possible. In high transverse positions, forceps should not be used, as rota- tion is not then permissible, and the blades, apialied to the neck and thorax on the one side and upon the cranium on tlie other, can not, for the reasons just given, be safely employed in extraction. The choice in such cases, when speedy delivery is called for, lies between version and craniotomy. In mento-posterior positions, the rotation of the chin to the front by repeated applications of the forceps is inadmissible. In practice, such efforts do not succeed, while they are calculated to inflict injury upon both the mother and the child. Usually, if delivery becomes necessary because of danger to the mother, craniotomy should be re- 382 OBSTETRIC" SURGERY. sorted to.

EXTRACTION IN FOOT AND BREECH PRESENTATIONS. 3S3 as no immediate danger threatens either the mother or the child, should be one of watchfnl observation. As a rule, the results to the child are unquestionably more favorable when Xature does her work unaided. If, however, there be any faltering in the natural forces, the physician should be in readiness to avert, by prompt interference, the perils which in pelvic presentations are associated with delay. When an artificial breech-presentation has been produced by internal version, immediate extraction is usually advisable, as the act of version, when the entire hand has to be introduced into the uterus, is apt to com- promise the safety of the child. Strong uterine contractions, a roomy pelvis, a dilated cervix, and a relaxed state of the vaginal outlet, are conditions highly favorable to the success of the operation. Under such circumstances, artificial de- livery can be performed with celerity and ease. But these conditions, however desirable, are not absolutely indispensable. Thus, extraction is rarely indicated if the pains are good ; it is often necessary to deliver before the cervix has reached the desirable degree of dilatation ; and it is possible to drag the head of the child through a moderately con- tracted pelvis without inflicting upon it any permanent injury. There is always danger, however, in the last two cases, of not being able to extract the child rapidly enough to save it from asphyxia. The prognosis for the mother is generally favorable. Still, lacera- tions are apt to follow the forcible delivery of the head through the undilated cervix. Extraction is commonly performed with the patient on her back. In easy cases she may occupy the usual position in bed, while the phy- sician places himself at her side. If difficulty is anticipated, the pa- tient should be placed crosswise, with hips raised by a hard cushion, and brought over the edge of the bed ; or, better still, may be placed upon a table, as the operator is then enabled to draw downward in the direction of the superior strait without kneeling before her. It is de- sirable to have two assistants to hold the patient's knees. To one of these should likewise be assigned the duty of making firm pressure, during extraction, upon the fundus of the uterus. If anaesthesia is thought necessary, a third assistant will be required. The question of anaesthesia is not always easy to decide. Useful in unruly patients, and where the entire hand must be passed into the vagina, its occa- sional suspensive action upon the uterine pains and the loss of the co-operation which intelligent patients are capable of affording are alloys to its beneficent action in stilling pain. My preference is to anaesthetize lightly at first, and then be guided by events as to whether the insensibility shall be subsequently made complete, or the patient be allowed to return to partial consciousness. As in all obstetrical operations, in addition to the usual aseptic pre- cautions, care should be taken to insure the emptying of the bladder 3g^ OBSTETRIC SURGERY. and rectum, and the operator should have iu readiness, in case of need, forceps, a soft fillet, Avarni napkins, hot and cold water, and a small English (No. 7) catheter, for use should the child be born in a state of partial asphyxia. The operation is divisible into three acts : 1. Extraction of the trunk as far as the shoulders; 2. Extraction of the arms; 3. Ex- traction of the head. First Act: Extraction of the Trunk to the Shoulders. The extraction of the trunk should take place slowly, with pauses between the tractions, in imitation of the uterine expellent forces. Tractions are best made during the pains only, when the latter do not recur at too long intervals. It is desirable that the uterus be closely retracted upon the child during the entire period of its expulsion. Where this does not occur, the arms are liable to be brushed upward to the sides of the child's head, the chin to become extended, and the mechanism of the head-delivery to be disturbed. Hemorrhage, too, is more likely to follow hasty delivery than where the uterus has had time to pass slowly into a state of complete retraction. When, there- fore, it is necessary to extract during the intervals between the pains, firm pressure should be made upon the uterus through the abdominal walls, so as to maintain them in close contact with the foetus. Steady tractions are preferable to pendulum movements. Tractions should be made downward and backward, in the direction of the superior strait, until the breech meets with the resistance of the floor of the pelvis. These general rules are applicable to every case of extraction. Special differences of procedure result from the presentation of one or both feet, and of the entire breech. Extraction by the Feet. — If a single extremity presents, the foot should be seized between the middle and index finger, with the thumb upon the sole, or across the instep. It is not necessary to go in search of the second foot, unless it crosses the first, or is reflected upward over the child's back. When the leg is drawn outside of the vulva, it should be wrapjsed in a warm napkin, and grasped by the entire hand. Always, in seizing a limb, the thumb should be directed upward and applied to the dorsal surface. The napkin serves partly to prevent the hand from slipping, partly to protect the surface from air, which at times is capable of exciting reflex respiratory movements. Tractions should be made downward, to avoid friction at the symphysis pubis. Until the pelvis is delivered, the child should be seized as near the maternal parts as possible. The hand, therefore, should be shifted u])- ward as the limb is drawn out of the vulva. Whichever extremity is seized rotates forward under the symphysis pubis during extraction. For this reason, when an election is practicable it is desirable to draw upon the anterior leg, since owing to the slight amount of rotation EXTRACTION IX FOOT AND BREECH PRESENTATIONS. 385 involved there is less likelihood of derangement of shoulder and head mechanism as these engage in the pelvis. So soon as the breech reaches the pelvic floor, traction should be made more in an upward direction, to facilitate the passage of the buttocks over the perinaeum. After the breech has cleared the vulva, the index-finger of the free hand should be carefully inserted into the fold of the posterior thigh, while the thumbs of both hands are placed upon the sacrum. During the subsequent extraction of the trunk the lower leg falls from the vagina without special assistance. If both extremities present, they should be seized so that the mid- dle finger is placed between the feet, while the index- and ring-fingers encircle the external malleoli. After they have passed sufficiently far outside the vulva, the left leg should be seized with the left hand and the right foot with the right hand. During extraction the normal rotation of the child may be aided by dragging with somewhat greater force upon the limb, which should be turned to the front. Fig. 160.— Method of seizing the breech. Extraction by the Breech. — When the breech alone presents, with both extremities reflected upward parallel to the anterior surface of the 25 3g(j OBSTETRIC SURGERY. child, spontaneous delivery is sometimes, as pointed out by Tarnier, prevented by the fact that the extended limbs act as splints which in- terfere with the lateral flexion of the trunk, and, consequently, with its accommodation to the curve of the parturient canal. If, m pure breech cases, obstetrical aid becomes necessary, the operator is em- barrassed by the absence of a natural handle by means of which extrac- tion can be effected. Theoretically, cephalic version by external manipulations, performed during the latter part of pregnancy or in the early stages of labor, most completely fulfills the required indications, viz., the saving of the child with the least possible risk to the mother. That, in cases where the breech is not engaged in the pelvic cavity and the membranes are intact, external version may be successfully accomplished, has been shown by Mattel, Hegar, and Pinard. Tarnier at first opposed the measure on the ground of its impracticability and the risk of rupturing the membranes before the version was completed, thus converting a breech into a shoulder presentation, but more recently has practiced the procedure in many cases without inconvenience to the mother or child.* Its successful performance presupposes a relatively consider- able quantity of amniotic fluid, the absence of reflex irritability in the patient, and experience on the part of the operator in mapping out the fretus through the abdominal wall. Ahlfeld f advises that in pri- mipara? the hand be introduced immediately after the rupture of the membranes, or at least while the introduction is still practicable, and that the anterior extremity be brought down as a prophylactic measure, leaving the child to be expelled subsequently by the natural forces. The hand should be passed over the anterior surface of the child to the knee ; the thumb should then be placed in the popliteal space, while four fingers grasp the leg, flex it upon the thigh, and draw it down into the vagina. The operation is facilitated by placing the patient upon the side to which the chiUrs feet are turned. But Kiistner, in common Avith most authorities, objects that the mancBuvre is apt to weaken the uterine contractions and to favor prolapse of the cord. In others words, in order to avert a remote danger, a near one quite as serious is invited. If, however, it becomes necessary to expedite delivery, without doubt, in all cases where it is possible to pass the hand to the fundus and bring down an extremity without imperiling the uterine struct- ures, this method should be employed by preference. But emergencies rarely arise before the breech has descended into the pelvic cavity. Most frequently the membranes have already ruptured, and the uterus has retracted upon the foetus. Under such conditions the intro- * Ollivier, De la conduite a tenir dans la presentation de I'extremite pelvienne. Mode des fesses, p. lO-S, Paris, 1883. f Ahlfeld, Arch. f.

Traction upon the extremity seized is not always followed by its descent, and where force is used the descent may be accomplished Fig. 161.— Method of seizing both extremities. at the expense of a fracture. To be sure, the manoeuvre is supported by the high authority of Dr. Barnes. " The wedge formed by the ex- tended legs and the upper part of the trunk must," he says, " in some instances at least, be decomposed Ijefore delivery can be effected." He recommends complete anaesthesia, support of the fundus, gentleness in passing the breech at the brim, and applying the fingers to the instep. But Barnes does not conceal the difficulties of the operation, nor the address requisite for its successful employment, and many accoucheurs, less fortunate, have recorded their failures to decompose the wedge in the manner advised. In a few cases, influenced by Barnes's teachings, I have, under most difficult conditions, succeeded in bringing down a foot ; nevertheless, I would advise the utmost caution in practicing the method, and that in all cases the operator desist the moment address fails and force becomes necessary. If, at the time intervention be- ggg OBSTETRIC SURCxERY. comes necessary, the breech is well engaged, the foetus is of ordinary size, and the resistance of the pelvic floor is inconsiderable, the expul- sion of the child may sometimes be effected by graduated pressure upon the fundus of the uterus. Should this measure prove ineffective, manual extraction should be attempted. To this end the index-finger should be inserted into the fold of the anterior groin and traction made directly downward. By seizing th3 wrist with the disengaged hand, an increase of traction-power can be exerted. If the breech is low, both index-fingers may be employed— the one in the anterior, the other in the posterior groin ; or the entire hand, passed over the sacrum, may seize the pelvis with the thumb in one groin and the index-finger in the other. Many writers insist upon manual extraction to the exclusion of all other methods ; but in primiparous women they are liable to fail at the critical moment. Instrumental aids then become necessary. The choice consists in the forceps, the fillet, the blunt hook, and, when the child is dead, the cephalotribe. So far as the relative value is con- cerned, I would recommend them in the order given. The chief objection urged against the forceps is that, by its con- struction, it is designed to seize the fetal head. As a consequence, when applied to the breech to which its curves are not adai)ted, it does not grasp the presenting part securely, and is liable to slip off when tractions are employed, thus endaiigering the maternal soft parts. If, with the view to prevent slipping, the handles be compressed firmly, it has been argued that fracture of the thighs may result, the circulation of the cord may be accidentally arrested, or fatal injuries may be inflicted upon the foetus by the pressure of the points of the forceps against the abdominal viscera. Miles,* to obviate these drawbacks, has devised a pair of breech forceps, apparently well designed for seiz- ing the pelvic extremity. As, however, a forceps of special construc- tion is likely to be but rarely at the disposition of the physician when an emergency calls for action, it is not without interest to know how far the ordinary instrument is available in practice. Omitting earlier authorities, we find in modern times Jacquemier declaring that " it is inexact to state that the forceps would crush the pelvic bones, and in- evitably kill the foetus by bruising and lacerating the abdominal vis- cera." Tarnier stated, in his famous article on the forceps, published in the Dictionnaire de medecine et de chirurgie, 1872, that, under exceptional circumstances, neither Stoltz nor Dubois feared to apply the forceps to the breech, and added that he had a number of times imitated their practice with success for the mother, and sometimes for the child. When the foetus was dead, he assured himself at the autopsy that the forceps had produced no lesion either of the pelvis or of * Miles, The Forceps in Difficult Breech Presentations, Am. Jour.

EXTRACTION IN FOOT AND BREECH PRESENTATIONS. 3S9 the cibdo)iiinal viscera, lliiter, in his excellent treatise on Obstetri- cal Operations (Leipsic, 1874), declares that no better instrument ex- ists for the extraction of the breech. Dr. Henry Fruitnight, of New York city, published in July, 1877, in the Virginia Medical Monthly, a successful case where the forceps were used at the suggestion of Dr. E. C. Harwood. Dr. I. E. Taylor has applied the forceps to the breech six times with success. In 1877 Haake* published five cases in which, as he says, to the astonishment of the physicians present, the extraction with the forceps was easily and quickly ended without detriment to the foetus. In the same year Agnew reported two successful cases to the London Obstetrical Society. I once saw, in consultation with Dr. F. A. Castle, a case of breech presentation in a primipara past her thirtieth year, where, after ineffectual essays at manual extraction, I applied the forceps over the sacrum and the anterior surface of the Fig. 162.— Tarnier forceps applied to the thighs. (Ollivier.) thigh. Though the breech had not completed its descent through the cervical canal, and the parts were rigid, the child was easily extracted in about fifteen minutes. The child was alive, and the trifling press- ure-marks disappeared in a few days. Recently I have had occasion to apply the forceps to the breech in the case of an elderly primipara, where the rigidity of the soft parts was extreme. The operation occu- pied nearly an hour. The patient suffered no inconvenience, and only * Haake, Ueber den Gebrauch der Kopf zange zur Extraction des Steisses, Arch. t Gynaek., vol. xi, p. 558, Berlin, 1877. 390 OBSTETRIC SURGP^KV. a slight abrasion was found npon the thigh of tho chihl which was born living. Dr. Harvey, Professor of Midwifery m the Medical Col- lege of Bengal, in an essay (1884), reports six cases. In three out ot six the success was complete, in one the forceps was without avail, while in the other two, although the instrument slipped, it did not do so until it had brought down the breech, so as to allow him m one case to get his fingers over the groin, and in the other to apply the fillet, wliich he had previously failed to do. Since the invention of axis traction by Tarnier a new impetus lias been given to the method. With axis traction, not only is the resist- ance offered by the parturient canal diminished, but, as Pmard states, the pressure is regulated, and is not increased by traction. The fetal Fig. ](i3.— The fillet in dorso-anterior positiou. (Ollivier.) part is seized solidly, and with the least risk of harm. Ollivier reports successes with Tarnier's latest model in his own practice, and in that of Budin, Thomas, Berthout, Lobat, and Cayla. Thus it will be seen that the weight of expei'ience is favorable to the forceps as a breech -tractor, while the objections are mainly theo- retical. The instrument is inadmissible so long as the breech does not engage in the pelvic cavity. Haake limited its use to cases in whicli the breech was already at the pelvic outlet, and only after complete rotation had taken place. With axis-traction forceps the indication is certainly extended, as a rule, to all cases where the breech has passed the pelvic brim and the dilatation of the os is well advanced. If rota- tion has taken place, the blades should be applied, respectively, over the EXTRACTION IN FOOT AND BREECH PRESENTATIONS. 391 sacrum unci over the posterior surface of the thigh, as recommended by Haake. If the hips are transverse, Ollivier advises that the blades be applied to the lateral surfaces of the thighs. The application of the blades over the trochanters, with the extremities overlapping the crests of the ilia, is to be deprecated, as the ilia are conijiressible and allow the forceps to slip (Ollivier). The extraction of the child should not be made an exhibition of strength. The rigidity of the maternal structures is rarely to be overcome by any justifiable degree of force. The slow descent of the breech, effected by intermittent traction, best insures the physiological softening of the tissues in advance of the pre- senting part. As the genital canal softens and relaxes, but little force Fio. 164.— The fillet in dorso-posterior position. (Ollivier.) is required to effect the birth of the breech. The tractions are most effective if made during the pains. They should be aided by simul- taneous pressure exerted by an assistant upon the fundus of the uterus. If the forceps fails, or, owing to the non-engagement of the breech, is contra-indicated and an extremity can not be brought down without the employment of force, a resort to the fillet is admissible. The ob- jections urged to its use are : 1. That the fillet is apt to become twisted, and that, when moistened with the vaginal secretions, it may form an uneven band, which, even with care, is capable of cutting deeply into the tissues ; 2. That in some cases it causes partial extension of the extremity, and, as a consequence, slips forward upon the thigh, whence 392 OBSTETRIC SURGERY. fracture of the thigh-bone becomes inevitable. The reports from tlie Lying-in Institution of Munich, where, owing to the advocacy of Hecker, the fillet has been assiduously tested, do not confirm the idea that these accidents are of necessary occurrence. Thus, in the last re- port of Von Weckberger Sternefeld, the records of thirty cases — twenty- one primiparae and nine pluriparae — are given. The mothers all did well. One of the children was in a macerated condition when the fillet was employed. Of the remaining thirty, twenty-four were born living. Of these, eight were partially asphyxiated, but seven were revived. In no one of the children born dead was the result attributable to the method of extraction employed. Twenty-three of the children left the institution in a healthy condition. In four cases, deep pressure-marks, but without excoriation, resulted from the use of the fillet. In the others, either no traces of pressure were found or they were of an in- significant nature. In all, the marks had disappeared in a few days. In one instance only fracture of the thigh occurred. The back was turned to the right and to the rear. Ollivier has shown that it is in dorso-posterior positions that especial caution is called for when trac- tion is made at the groin. A glance at Fig. 164 will show that it is not easy in these cases to direct the tractions in such a way as to avoid the partial extension of the thigh and the transfer of the pressure to the shaft of the thigh-bone. This extension, Ollivier suggests, can be prevented by passing the fingers into the rectum and pressing the breech forAvard as tractions are made. The fillet should be jaassed over the anterior thigh, the tractions should be of moderate force, they should be made during the pains, and should be sustained by external pressure made by a skilled assistant. The passage of the fillet around the groin by the finger alone is by no means always easy in the class of cases in which the fillet is principally indicated, viz., in those where the breech is high and difficult of access. To be sure, with pa- tience the knotted end of a handkerchief can sometimes be pushed around the groin, or, failing in this, an elastic catheter with a loop attached to the ex- tremity may be guided by a finger in the groin down between the thighs, to serve as a means of conducting the fillet into position. Many ingenious instruments have been especially devised to serve as porte- fillets. Of these, Ollivier's instruments, modified by him from an invention of Tarnier, will serve as an example. It consists of a long-handled blunt hook, with a central tunnel and a terminal olive-shaped bulb. Through the central canal a long piece of whalebone is passed. The extremity of the whalebone terminates in a metallic eye, which occupies, when the whalebone is withdrawn, a hollow space in the olive-shaped extremity of the blunt hook. Below the handle the end of the whalebone is armed with a button, to prevent it from being accidentally withdrawn into the canal. A screw above the handle serves to fix the bone at any point deemed desirable. The blunt hook is adjusted by passing it upward along the side of the child, directed to the front to a point above the pelvis, and then directing the curve so as to adjust it to the groin. The whalebone is then easily pushed forward until it is felt by the fingers of EXTRACTION IX FOOT AND BREECH PRESENTATIONS. 393 the physician between the thighs of the foetus. The metallic eye is next di- rected by the fingers outside of the vulva. The attached fillet is easily with- drawn by reversing the directions given. The fillet employed may be of any material. In emergencies the nearest object can be made to serve. It is desirable that the fillet should be adjusted GrWtlAkUUBttO. Fig. 10.5.— Porte-flllet. (.OUivier.) without forming folds or creases. OUivier recommends passing a lacing through a piece of rubber tubing the size of the little finger. The lacing should be fixed by stitches to the ends of the tul)e, a i^rojecting portion serving to attach the tube to the eye at the end of the whalebone. In Ollivier's experiments the ^^^--JJibber tubing acted admirably in protecting the tissues of the child from harm- ful pressure. In the absence of other appliances, or should failure attend the measures already described, it is well to remember that the blunt hook owes its sinister reputation not so much to its inherent defects as to lack of proper caution in its employment. It will not break the femur if adjusted in the groin. It will not produce serious contusions if the blunt end is carefully guarded by the finger. Injuries to the maternal tissues can only occur where leverage movements are made. So long as the pressure of the curved portion is confined to the groin, serious lesions are not likely to be produced. Steady downward trac- tions, made with moderate force and with a hand in the vagina to guard the point of the instrument, and to give warning of commenc- ing extension of the thigh, will in the rule suffice to prevent serious accidents. No instrument is capable of seizing the breech so securely as the cephalotribe. If, therefore, the child be dead — a fact rarely to be de- termined except in cases where the cord can be reached — the cephalo- tribe, screwed tightly to the breech, can be trusted to act as a reliable tractor. Management of the Cord. — So soon as the cord has passed beyond the vulva, dragging upon the navel should be avoided by genth' jjull- ing the cord downward into one of the recesses to the sides of the promontory until some resistance is experienced. Sometimes the cord is found passing between the child's legs and up over its back to the placenta. Then traction should be exerted upon the placental ex- tremity, and an attempt made to slip the loop over the posterior thigh. In the rare cases of failure to obtain its release, and where the cord is wound around the child's body, either two ligatures or compression 394 OBSTETRIC SURGERY, forceps should be applied, aud the cord be divided between them, whereupon every effort should be put forth to complete the delivery as speedily as possible. Seco^td Act: Liberation^ of the Aems. When the Arms are flexed upon the Thorax.— After providing for the safety of the cord, the pelvis of the child should be seized m the two hands with the thumbs upon the sacrum. Traction should be employed in a downward direction until the shoulder-blades make their appearance. Then no time should be lost in liberating the arms. If the latter are folded upon the chest, delivery is an easy matter. The palmar surface of the corresponding hand is passed over the belly of the child to the posterior arm (back to the right, right hand, and vice ver- sa), while the extremities, wrapped in a warm cloth, are drawn in the opposite direction. The forearm should be seized as near the wrist as possible, and be brought down over the abdomen to the side of the child. When the Arms are extended.— Unless, however, great care has been exerted during extraction to keep the uterus by external pressure closely in contact with the foetus, the friction of the parturient canal is apt to brush one or both arms upward to the sides of the child's head. In such cases the difficulties involved in liberating the arms are often very great. Here, too, owing to the increased amount of space afforded by the curvature of the sacrum, an attempt should first be made to re- lease the posterior arm. Release of the Posterior Arm. — This is best accomplished by draw- ing the lower extremities strongly upward and to the side, thereby causing the posterior shoulder to sink deeper in the pelvis and to furnish more room for the introduction of the hand ; then two fingers should be passed along the side of the child to the elbow-joint, which should be pushed across the face, and be brought down over the thorax. In case the foregoing manoeuvre can not be rapidly executed, the operating hand may be removed, and the extremities of the child may be drawn in the opposite direction, while the hand which at first had seized the feet or breech should pass upward over the abdominal surface to the posterior elbow. The latter should then be directed forward, by means of two fingers in the Joint, toward the anterior pelvic wall. Whether the hand be passed behind or in front of the child, it should be introduced slowly and without force during the intermis- sion between the pains. Pressure should always be made at the joint, and never upon the humerus. A forgetfulness of the latter rule is apt to produce fracture. Release of the Anterior Arm. — As there is rarely space enough be- EXTRACTION IN FOOT AND BREECH PRESENTATIONS. 395 tweeu the sym})hysis aud the shoulder to allow the iingerrf to rqach the elbow, it is customary after release of the posterior arm to rotate the trunk so as to bring the anterior arm backward into the cavity of the sacrum. This is accomplished with the least disturbance of the nor- mal mechanism by seizing the released arm and drawing it upward on the dorsal side of the child. The shoulders readily follow the move- ment until the half-circle rotation is completed. Exceptional Cases. — The shoulders, in place of rotating into the conjugate diameter, may enter transversely into the pelvis. If the back then be turned toward the symphysis, the hand should be passed over the abdominal surface in search of the arms. The space oppo- site the sacrum renders this movement one of easy execution. When the back is turned to the rear, so long as the arms are flexed, the hand should search for them under the symphysis pubis. If, however, they are extended upon the sides of the child's head, it is rarely possible to push the arms forward between the face and the symphysis pubis. An effort should be made, therefore, to bring one arm to the rear by rotating the thorax with the hands. Michaelis succeeded twice in similar cases without rotating the trunk, by passing the hand behind the dorsal surface of the child and drawing the elbow backward and downward below the side-wall of the pelvis, and then pushing the forearm over the thorax.* I have repeatedly tested this movement in passing the cadaver of an infant through a bony pelvis, and find that it can be accomplished without producing fracture or dislocation. Of course, during the life of the child the result may be different. Sometimes, in rotating the shoulders, the anterior arm becomes displaced backward, so that the forearm is thrown across the neck of the child. When this accident is of recent occurrence, the release of the arm may be accomplished by pressing the thorax of the child back- ward into the genital passage, and rotating the body in the reverse direction from that which produced the difficulty. If, however, trac- tions have been made upon the child until the head has entered the pelvis, the arm may become so compressed between the neck and the symph3^sis pubis as to render its liberation a very difficult if not im- possible task. Then every resource should be quickly tested to turn the shoulder of the displaced arm to the rear, either by raising the re- leased arm, or by rotating the thorax, or by drawing upon the elbow. In case of failure to obtain a speedy result, extraction may be at- tempted without releasing the arm. To be sure, fracture of the humerus is thereby rendered highly probable ; but if the bystanders are forewarned that the risk is incurred in the interest of the child, they are generally ready, where the life of the latter is preserved, to condone the injury. In setting a fractured arm, soft jiads should be baiulaged upon the * Michaelis, Abhandlungen. Kiel. 1833. p. 230. 3,j(3 OBSTETRIC SURGERY. auterior and posterior surface to hold the extremities in position. The posterior pad should run the entire length of the arm ; the anterior pad need not extend below the elbow. The arm should then be band- aged to the thorax. In two or three weeks consolidation takes place.* In performing artificial rotation, it is well to bear the warning of Dr. Barnes in mind, viz., " That the atlas forms with the axis a rota- tory Joint, so constructed that, if the movement of rotation of the head be carried beyond a quarter of a circle, the articulating surfaces part immediately, and the spinal cord is compressed or torn.^f Pains should accordingly be taken to note, when a half-turn is given to the body, whether the head follows the movements of the trunk. Third Act: Extraction of the Head. In the extraction of the head we have to distinguish— 1. Cases in which the head has entered the pelvis, and has only to overcome the resistance of the perineum ; 2. Cases where the head is retained at the brim by pelvic contraction, stricture of the os uteri, extension of the chin, or insufficient expulsive action exerted by the uterus and the abdominal muscles. 1. Extraction of the Head after it has entered the Pelvis. Smellie's Method. — In the so-called Smellie's method the trunk of the child is wrapped in a warm napkin and placed astride the operator's arm ; the hand is then passed into the vagina, and the index and middle fingers are placed upon the fossaj caninae to the sides of the child's nose. At the same time, upward pressure is made with the fingers of the other hand upon the occiput. By this means flexion of the head is induced. Then by raising the trunk the face is rolled out over the perina3um. This method possesses the advantage of avoiding the risks of injuring the child which are incident to the other procedures. It requires for its successful performance the completion of rotation, a small head, and a lax perin^eum. Combined Traction upon the Chin and Shoulders. — In case the fore- going plan is not followed by immediate success, the two fingers upon the fossae caninae should be introduced into the mouth, and the index and middle fingers of the other hand should be forked upon the shoulders. Tractions should be made somewhat downward, until the neck has been drawn below the pubic arch and the chin has reached the coccyx. Then, with occiput resting against the pubic walls, by a deliberate joint movement of the two arms the body should be raised, and the face and brow be made to rotate over the coccyx and perinaeum. By this method there is obtained the greatest amount of traction force in combination with the least degree of violence to the child. As the power is exerted chiefly upon the shoulders, the fingers in the mouth are not likely to * Spiegelberg, Lehrbuch, etc., p. 809. f Barnes, Obst. Operations, Am. ed., p. 210. EXTRACTION IN FOOT AND BREECR PRESENTATIONS. 397 fracture the jaw, but by keeping the chin flexed and drawing gently uto- it, the danger of twisting the neck, in cases where the rotaUon of the face into the hollow of the sacrum is incomplete, is avoided.

Tractions should be made downward, so that while the neck rests upon the perineum the fore- head rotates under the symphysis pubis. Ordinarily, when the head enters the pelvis in a transverse direc- tion, the occiput rotates to the symphysis pubis during extraction. Should the head, however, remain with its long diameter in the trans- verse diameter of the pelvis, a hand introduced into the vagina, with the back to the sacrum and the fingers over the chikFs face, may sometimes be successfully employed to rotate the latter into the sacral con- cavity. •2. Extraction with the Head at the Brim. — W'itli the head at the brim, the combined method as given above is available in all ordinary emergencies. As, however, the life of the child de- pends upon the speedy extraction of the head, it is well to become familiar with the various procedures, as, by pass- ing rapidly from one to another, a suc- cessful result is often obtained, when failure might have followed ineffectual efforts in a single direction. The Prague Method owes its mod- ern name to tbe advocacy of Kiwisch, ►Scanzoni, and Lange, all representatives of the Prague school. It was, however, nearly a century earlier described by Pugh. It consists in seizing the feet with one hand, and directing the body of the child nearly vertically downward. The fingers of the other hand are hooked over the shoulders of the child, so that the tips rest upon the supra-clavicular region. Traction is exerted by both hands simultaneously. In the absence of pains, external pressure upon the head should be made by an assistant through the abdominal walls. Care should be taken to avoid twisting the neck, and to preserve the normal relations between the head and the shoulders. After the head has passed the brim and fairly entered the pelvis, the hand upon the neck is em- ployed as a fulcrum, while the extremities are raised rapidly toward the abdomen of the mother ; the friction from the inner surface of the symphysis pushes the occiput upward, and forces the face to de- FiG. 167.— Extraction by the Prague method.

When the chin is directed to the front, and at the same time is arrested at the symphysis pubis, if the occiput occupies the hollow of Fig. 168.— The Prague method of extracting head. the sacrum, the body of the child should, during the tractions, be directed toward the abdomen of the mother, so as to cause the occiput to rotate over the perineum. The so-called Prague method is particularly serviceable in cases of flattened pelvis, in which the chin normally is partially extended as the head engages in the sagittal diameter of the brim. Forceps to the After-coming Head. — The forceps to the after-com- ing head has been condemned by some and warmly approved by others. As, however, with its aid I have in a number of instances extracted children alive in cases where the foregoing methods have failed me, it is now my custom to have the blades duly warmed and ready to hand before attempting manual extraction. The instrument is occasionally of use in overcoming the resistance of a rigid perinseum in strongly built primiparae, but is chiefly indicated when both occiput and chin are arrested at the superior strait. With the chin anterior, the forceps should be applied under the back of the child, and the handles raised so as to bring the occiput into the hollow of the sacrum. With the 400 OBSTETRIC SURGERY. chin to the rear, the forceps should be applied uuder the abdomen, and be used to draw the face into the sacrum. Where the arrest of the head is due to stricture of the os externum or internum, the forceps will sometimes bring the head rapidly through the cervix, when trac- tion upon the feet only serves to drag the uterus to the vulva. In stricture of the cervix, however, great care must be exercised to avoid laceration, as uuder no circumstances are extensive ruptures of the lower uterine segment so apt to follow as in the forcible extraction of the after-coming head. Should this happen, the writer urgently Fig. 169.— Chin arrested at symphysis. (ChaiIly-Honor6.) counsels the immediate employment of the suture, as the dangers of childbed are thereby diminished, and much immediate and prospect- ive suffering are prevented. Tlie introduction of a large-sized catheter into the child's mouth and drawing back the perinaeum have been found useful as temporary means of introducing air into the child's lungs, where delay attends efforts at delivery. In extracting the after-coming head, the axis-traction forceps is particularly serviceable. CHAPTER XXI. VERSION. Cephalic version. — External method. — Combined method.

It is customary to designate specifically the character of the version by mentioning — 1. The presentation to be changed. Thus, versioii is made from the head, the breech, or the shoulder, as the presenting part. 2. The presentation to be effected. The term cephalic version is used where the head is brought to the brim of the pelvis, and po- dalic version where the feet are seized and the extremities made the presenting part. 3. The method adopted by which version is accom- plished. The expression external version is applied to manipulations exclusively through the abdominal walls ; internal version, to the in- troduction of the entire hand into the uterus ; and the combined method to cases in which both hands, the one externally and the other with two to four fingers introduced through the os, co-operate together. Cephalic Version. — When it is simply required to rectify a faulty presentation (shoulder or transverse), without reference to modifying circumstances, cephalic version unquestionably deserves the preference. In practiee, however, this method requires the concurrence of so many favorable conditions that its employment is very limited. For instance, there must be no comjjlications which call for rapid delivery. It would be unsuitable in prolapse of the cord and in cases of placenta previa. There should be nothing to prevent the child's head from entering the brim of the pelvis. It should, therefore, not be attempted in con- tracted pelves. A prolapsed arm, unless previously replaced, would render the operation impossible. The child should enjoy a considera- ble degree of mobility. An abundance of amniotic fluid contributes much, though it is not indispensable, to success, as, even after the rupture of the membranes, provided the uterine walls are sufficiently relaxed, the head may be brought into the pelvis. Before rupture, excessive sensitiveness to manipulations, and, after rupture, rigidity of the uterus, stand in the way of success. The operation may be performed by either the external or the com- bined method. Of the external methods the best is that which is known as AVi- gand's (1807), which combines a suitable position of the mother with manipulations through the abdominal walls. The mother is at first made to lie upon her back, with knees fiexed, and with the abdomen exposed or covered by some light material. The j^hysician stands by the side of the patient, looking in the direction of her face. He be- gins by laying his hands flat upon the surface of the abdomen, and seeks with the one the head and with the other the breech of the fostus. During the intervals of the pains, by gentle movements of the two hands working simultaneously, he strives to press up the breech and anterior surface of the child and to bring the head into the peb ic 26 402 OBSTETRIC SURGERY. brim. Should the uterus harden, all friction movements of the hands should cease, and the efforts of the operator be confined to holding the foetus steady in the position previously produced. The movement may be aided by turning the woman upon the side toward which the head is directed. As the fundus of the uterus sinks to the side upon which the woman lies, it carries the breech of the child with it, while the change in the uterine axis tends to throw the cephalic end in the op- posite direction. When the head is once brought to the brim of the pelvis it may be retained in situ, if the patient lies upon her side, by the hand of an assistant, or by a small, hard pillow pressed firmly against it. If the patient lies ujDon the back, two compresses may be laid along the sides of the uterus near the head, and a bandage ajoplied to the abdomen to keep them in i^osition. When the pains are regular and the cervix partially dilated, fixation of the head may be accomplished by ruptur- ing the membranes and allowing the waters to escape. Until the uterus retracts down upon the child, the head should be held at the brim either by the two hands through the abdominal walls, or by the thumb and four fingers of one lyind applied directly to jthe head through the cervix. The more important of the combined methods are those of Busch, D'Outrepont, Wright, Hohl, and Braxton Hicks. They have in com- FiG. irC— D'Outrepont's method, modified by Scanzoni. mon the simultaneous employment of the external and internal hand. They differ, however, in detail. The methods of Busch and D'Outre- pont have now chiefly an historical interest. Busch introduced the hand corresponding to the child's head through the vagina and cervix, while counter-pressure was made with t!ie other hand upon the fundus VERSION. 403 uteri. The back of the hand is at first directed to the front. When, however, its widest portion has passed above the symphysis pubis, the back of the hand is turned to the concavity of the sacrum, and the fin- gers are pushed up with care between the membranes and the uterus to the head. The membranes are then ruptured, and during the escape of tlie waters the head is seized by the fingers and thumb and drawn into the pelvis, while the disengaged hand presses the breech toward the median line. Every pains should be taken to prevent, with the fingers, the prolapse of the cord, or of an arm,* during the escape of the water. D'Outrepont seized the presenting shoulder between the thumb and fingers of the hand corresponding to the breech, and, during the intervals between the pains, pushed the shoulder upward and in the direction of the breech until the head descended into the pelvis. During this manoeuvre D'Outrepont simply used the external hand to support the uterus. Scanzoni recommended that it should be employed externally to press the head toward the pelvic brim.f Wright's method differs from that of D'Outrepont, in that he em- ployed, to seize the shoulder, the hand corresponding to the head, and while he pushed the shoulder, without lifting, in the direction of the curve of the uterus, he applied the remaining hand to dislodge the breech, and move it toward the center of the uterine cavity. J All the foregoing methods require for their successful performance a movable foetus and a dilated cervix — conditions which render podalic version safe and of easy execution. In practice, therefore, they have never enjoyed any considerable degree of popularity. Of far greater importance are the methods of Hohl and Braxton Hicks, which, pos- sessing the advantage of requiring the introduction of two fingers only into the uterus, can consequently be resorted to at an early stage of labor. Hohl, like Wright, employed for internal use the hand corre- sponding to the head. With two fingers in the cervix, he pushed the top of the shoulder in the direction of the breech, and pressed the head into the pelvis with the external hand. At the same time he in- trusted to an assistant the task of seizing the fundus of the uterus be- tween the palms of the hands, and directing it to the side toward which the head was originally turned.* Braxton Hicks describes his method as follows : " Introduce the left hand into the vagina as in podalic ver- sion ; place the right hand on the outside of the abdomen, in order to make out the position of the foetus and the direction of the head and feet. Should the shoulder, for instance, present, then push it, with one or two fingers on the top, in the direction of the feet. At the same time pressure by the outer hand should be exerted upon the cephalic end of the child. This will bring down the head close to the * Scanzoni, Lehrbuch der Geburtshiilfe, 1867, Bd. iii, p. 63. t Op. cit., p. 65.

OS ; then let the head be received upon the tips of the inside fingers. The head will play like a ball between the hands, and can be placed m almost any part at will. ... It is as well, if the breech will not rise to the fundus readily after the head is fairly in the os, to withdraw the hand from the vagina and with it press up the breech from the exterior." * Lately, Hicks has proposed to employ the external hand to alternately press the head into the os and the breech to the fundus. His plan differs from that of Hohl, in that he operates with the pa- tient upon the side, and uses the left hand with the patient upon the left side, and the right hand when she lies upon the right. He like- wise dispenses with an assistant. f Podalic Version.— Podalic version is indicated in the following cases : 1. The transverse presentation, where cephalic version is contra- indicated, or attended with any considerable degree of difficulty. 2. In head presentations, where there is reason to suppose that the result would be favorably influenced by bringing down the feet. As illustrations of such conditions, we have faulty presentations of the head and face, prolapse of the cord and extremities, placenta prsevia, and contracted pelvis. The various contingencies which call for ver- sion will be more closely considered in connection with the special morbid conditions mentioned. The operation may be performed by combined external and inter- nal manipulations, or by the internal hand alone. The Bipolar or Combined Method of Braxton Hicks.— In the bi- polar method of turning, the two hands operate simultaneously upon the extremities of the foetus. It may be carried out at will with the patient upon the side or upon the back. The latter position is the one which finds most favor in this country. The patient should be placed transversely in the bed and the nates drawn to the edge. Two assistants are required to hold the legs, which should be flexed and ro- tated outward. As the beds in America are very low, where difficulty in operating is anticipated it is sometimes advisable to remove the patient after she has been anaesthetized to a table covered with a blan- ket or woolen comforter. Complete anaesthesia is useful as a means of facilitating the introduction of the internal hand, and maintaining a relaxed condition of the uterus. Care should be taken that both bladder and rectum are emptied. The hand selected for internal manipulations should be of the same name as the side to which the extremities are turned — i. e., feet to the right, right hand; feet to the left, left hand. J; The fingers should be brought together in the * Hicks, Combined External and Internal Version, Trans, of the Obstet. Soc. of London, vol. v, p. 230. t Hicks, Am. Jour, of Obstet., July, 1879, p. 593. X In England the patient is delivered upon the left side, and the left hand is commonly introduced into the vagina. In Germany, when the patient lies upon the VERSION. 405 form of a cone. The back of the haud and forearm should be well lubricated with oil or lard. In passing the hand into the vagina, the labia should be separated by the thumb and fingers of the disengaged hand. Entrance is effected by directing the fingers toward the sa- crum, and pressing backward upon the distensible perineum. In this stage of the procedure hasty action is out of place. Patience and gen- tleness are the prime requisites. Two or three fingers only need to be carried through the internal os. When the presenting part is reached, the external hand should be laid upon the abdomen, and pressure brought to bear upon the breech. The two hands should then move the extremities of the child in opposite directions. To quote Dr. Barnes, " The movements by which this is effected are a combination of con- tinuous pressure and gentle impulses or taps with the finger-tips on the head (or shoulder), and a series of half-sliding, half-j)ushing im- pulses with the palm of the hand outside." When the breech is well pressed down to the iliac fossa, the membranes should be ruptured during a pain, and a knee, which at this time is generally near the os internum, should be seized and hooked into the vagina with the fin- gers. As the breech is brought into the pelvis by tractions upon the leg, the outer hand should be employed to press up the head until the version is completed. The manipulations described are to be conducted during the inter- vals between the pains. Care should be taken not to hook down the cord with the knee. When the lower extremities are reflected upward upon the body so that a knee is not attainable, the breech may often be brought down by a finger inserted into the fold of the thigh, or by pressure upon some part of the pelvis. The combined method of version, which we owe in all its essential features to Braxton Hicks, is one of the most important contributions to obstetrical practice of the present century. It possesses the price- less advantages of enabling the physician to perform version early in labor, and to accomplish the operation without in any way imperiling the integrity of the uterus. The only prerequisites for success are : sufficient dilatation of the cervix to permit the passage of two fingers, a certain degree of fetal mobility within the uterine cavity, and a pre- cise knowledge of the fetal position. After rupture of the membranes and escape of the waters, the operation becomes more difficult, but is even then not always impracticable. Internal Version. — In internal version the entire hand is introduced into the uterus. It is necessary, therefore, that the cervix should be so far dilated that the hand can be passed without violence through the cervical canal. Irregular uterine contractions require to be relieved by hypodermic injections of morphia, with or without the addition of right side, the left hand is employed inside : when upon the left side, the right hand. The choice of hands, it will be seen, is not a matter of considerable importance. 406 OBSTETRIC SURGERY. atropia, or by the induction of comiDlete anaesthesia. As internal ver- sion is not an indifferent operation, but may be followed by inflamma- tions due either to injuries of the maternal tissues or to the introduc- tion of infected air into the uterus, it should not be attempted until the' impracticability of the combined method has been demonstrated. It is applicable chiefly to cases in which a certain degree of uterine retraction has followed upon the escape of the amniotic fluid,* The patient should be placed upon the back or side ; the bladder and rectum should be emptied; and anaesthesia should be pushed until the action of the abdominal muscles is suspended. The exact position of the foetus should be carefully ascertained. The hand should be rendered thoroughly aseptic, and should be passed slowly, after the expiration of a pain, with the fingers formed into a cone, through the vagina and cervix, opposite the sacro - iliac synchondrosis, upon the side of the child's feet. At the same time counter-pressure sliould be maintained over the fundus uteri, to prevent rupture of the vaginal attachments. If the uterus begins to contract, the fingers should be spread out, and the operator re- main passive until the pain sub- sides. In head presentations, the hand employed should be always the one which corresponds to the side of the child's feet. In transverse presen- tations, when version is performed soon after the rupture of the mem- branes, before retraction of the uterus has taken place to any extent, the choice of hands is of little consequence. This is especially true in the dorso-anterior position. Thus, when the child lies Avith the head to the left, feet to the right, and belly to the rear, the right hand may * If the membranes are intact, and internal version is chosen in place of the bi- polar method, one of three plans is open in practice: 1. Boer recommended passing the hand between the membranes and uterus to the feet of the child, and then rupt- uring the membranes; 2. Hiiter seized the feet of the child through the mem- branes, and turned without rupturing; 3. Levret ruptured the membranes at the OS uteri, and introduced the hand during the outflow of the water. The third plan is the one most deserving of favor. Fig. 171.— Version in head presentations. (Chailly-Honorg.) VERSION. 407 be passed directly across the belly to the extremities of the child, or the left hand may be made to pass from the breech, along the surface of the thigh, to the nearest knee or leg. By the latter method the danger of mistaking an arm for the leg is avoided. Should, in any ease, doubt upon this score arise, the characteristic differences between the hand and foot should guide us to a correct diagnosis. Thus, the wrist enjoys greater mobility than the ankle, the fingers are longer than the toes, the palm is shorter than the sole, the position of the thumb is peculiar to the hand, and the pointed heel to the foot. In the lateral position, the patient should be placed upon the side to which the child's breech is turned, with the buttocks near the edge of the bed. Here, obviously, the operator, standing in the rear of his patient, would use with the greatest facility the hand corresponding to the side upon which the woman lies (left side, right hand, and vice versa). In dorso-posterior positions especially, the advantages of such a selection are manifest. In easy versions, it is correct practice to bring down one foot or knee only. When one extremity is left reflected upon the abdomen, the larger size of the breech more fully distends the cervix, and thus prepares the way for the subsequent passage of the child's head. In difficult cases, or when rapid delivery is to be effected, both feet should be seized. A single foot should be held at the ankle between the thumb and fingers. When practicable, the entire leg may be grasped with the closed hand. When it is sought to turn by both feet, the middle finger should be placed between them, while the ankles are held by the second and fourth fingers. While in uncomplicated cases it is not a matter of great importance which extremity is selected, it is still proper to remember that, in ac- cordance with the rule that the limb drawn upon moves forward under the symphysis, the necessary amount of rotation is less when with the feet to the rear the lower, and with the feet to the front the upper, ex- tremity is subjected to traction. As in the bipolar method, during the traction upon the foot the external hand should aid versioA by pressure upon the head made through the abdominal walls with the disengaged hand. When, in transverse presentations, the membranes rupture, the lower arm not unfrequently becomes prolapsed into the vagina. As a rule, this complication does not embarrass version, though it may prove a hindrance to the introduction of the hand. It is a good plan, in arm presentations, to slip a noose of tape about the wrist, which serves a twofold purpose, enabling us to draw the extremity up toward the symphysis, or back against the perinasum, according as the hand is to be passed posteriorly or anteriorly, and to hold the arm to the side of the child's body during the performance of version, thus avoiding the difficulties of arm delivery in the period of extraction. Dr. F. P. 4:08 OBSTETRIC SURGERY, Foster, in a case where the mobility of the child was unimpeded, used the prolapsed arm as an aid to version in the followmg ingenious manner : The child lay with the back to the front, the head upon the right iliac fossa, and the left arm presenting. With the right hand in the vagina, he seized the arm and pushed gently upward m the di- Fig. 172.— Version in dorso-anterior position, first stage. Traction on lower limb.

In this way he succeeded in elevating the cephalic pole until with the index-finger alone in the cervix uteri he managed to reach the breech of the child. With the point of his finger he gently urged this along to the mother's right side, and soon encountered the left foot, which he readily hooked down into the vagina.* When, after rupture of the membranes, aid is not promptly ren- dered, the shoulder becomes crowded into the pelvic brim.

VERSION. 409 pains are feeble the uterus may remain relaxed, so that hours after- ward version may be readily performed. If the pains are good, how- ever, as the waters escape the uterus retracts, and finally becomes rigid- ly applied to the surface of the foetus. Under these conditions, the lower uterine segment, which contains the head and shoulder of the Fig. 173. -Version in dorso-anterior position, second stage. Traction on lower limb. (FarabcBuf and Varuier.) child, is often stretched to an extreme degree of tenuity. Version, under the circumstances, is embarrassed by the difficulty of introducing the hand into the uterus to seize the foot ; by the fact that when trac- tions are made upon an extremity, in place of the child turning in utero^ both child and the closely aj^plied uterus are apt to move to- gether ; and by the danger of rupture due to the difficulty of lowering the breech without simultaneously increasing the pressure exerted upon the thinned lower segment by the child's head. ^^Q OBSTETRIC SURGERY. In operating after the retraction of the uterus has become complete, the physician should seek to effect the utmost relaxation by pushmg anesthesia to complete insensibility. The hand should be mtroduced slowly and with the utmost gentleness. Precipitate action, or an at- tempt to overcome the uterine resistance by force, may cause fatal rupture Tlie external hand should make firm counter-pressure upon the fundus, to prevent the uterus from being torn from the vagina The seizure of the lower foot is usually alone practicable, himpson, it is true, regarded the secret of success in such cases as depending upon Fig. 174.— Version in dorso-posterior position. Traction on upper limb. (Faraboeuf and Varnier.) making tractions with the upper limb, as tending to rotate the body of the child upon its long axis, and thus favoring the release of the pre- senting shoulder from its imprisonment. However rational all this sounds in theory, rotation within a rigidly contracted uterus is easier to represent by diagram tlian to carry out in practice. The result of seizing the upper leg is usually to cross it with its fellow, and to twist the child's body so as to injuriously compress the abdominal viscera. By making tractions upon the lower leg, the breech is brought by the shortest route to the uterine orifice. To be sure, by this manoeuvre the body of the child is bent laterally, but lateral flexion does the child no harm. In case of failure to effect version, a noose of tape may be VEESION. 411 placed upon the foot, and the hand returned to seek the other extrem- ity. When the foot is within reach, the loop of the fillet, placed about the fingers, is easily conveyed upward to the ankle. When, however, the foot is high up in the vagina, where the movement of the fingers is impeded, some form of instrument is needed to push the loop from the Fig. 175.— Method of seizing the foot in breech cases. (Faraboeuf and Varnier.) fingers over the foot. Unquestionably the most serviceable contrivance to this end is the repositor of Carl Braun, which consists of a gutta- percha rod sixteen inches in length, with an aperture two inches from the extremity, through which the loop of a double tape is threaded. When in use this loop is passed around the noose of the fillet, and is then reflected over the end of the rod. Thus secured, the fillet is con- veyed to the position aimed at. Then, by loosening the ends of the tape, which during the upward movement are held to the sides of the 412 OBSTETRIC SURGERY. rod by the operator's hand, and by shaking the rod, the instrument is easily detached, and can be withdrawn without difficulty. If the operator does not care to release the foot, because of the difficulties he has encountered in getting possession of it, the fillet may be noosed around his arm, and thence be pushed upward over the hand, to the seized extremity. A device which in many instances has rendered me excellent serv- ice, has consisted of an ordinary catheter threaded with a doubled piece of twine, so that the loop projected from the eye of the mstru- Fig. 176.— Braun's repositor.

In case the second limb can not be reached, or where traction upon both extremities fails to bring the breech into the cervix, an attempt should be made to dislodge and elevate the presenting shoulder. This can sometimes be accomplished, in accordance with the suggestion of Professor Goodell, by bringing down the upper arm and turning the child upon its long axis ; or, while the noosed foot is held out of the way by the attached fillet, the hand corresponding to the child's head may be introduced into the vagina and employed to press the present- ing part away from the cervix. The raising of the shoulder should be gradual, and should be performed with the utmost gentleness, as the danger of uterine rupture is peculiarly enhanced by the thinned, over- stretched condition of the lower segment. Meantime a skilled assist- ant should exercise counter-pressure from without upon the fundus of the uterus and upon the head of the child, and aid the descent of the breech by rightly directed pressure. Eesolution to succeed, combined CRANIOTOMY AND EMBRYOTOMY. 413 with patience in manipulation, usually overcomes the obstacles pre- sented by the most difficult cases. In the few instances where failure follows all attempts to accom- plish version, or where rupture is imminent, or where the child is known to be dead, the obstacle to delivery may be overcome by decapi- tation, and the removal of the head and trunk separately.

To the perforation of the skull and the evacuation of the brain-contents ; and, 2. To the various procedures subsequently adopted to further minimize and extract the cranial walls. Indications for Perforation. — Perforation is resorted to, in cases of mechanical obstacles to delivery, to overcome the disj^roportion existing between the child's head and the parturient canal. As the operation is jDerformed solely in the interests of the mother, it possesses a wider range of applicability when the child is dead than when still living. Perforation, in the dead child, is allowable in difficult labors so soon as temporizing becomes dangerous to the mother. The mere aesthetic advantage of removing by forceps an unmutilated child ought not, if attended by any risk, to be allowed to weigh with the physician against the welfare and safety of the parent. If the child is alive, the question of perforation is one of the most serious that falls to the lot of the conscientious physician. If the life of the mother is at stake, and the sacrifice of the child is necessary to her preservation, few would dispute at the present day the superiority of the mother's claim to existence. Still, it is not sentimentality to feel that it is an awful thing to destroy a living child before a clear conviction is reached that conservative measures, which hold out the hope of preserving both lives, are of little or no avail. The proper position, however, of craniotomy, between the C cesarean section on the one hand and forceps and version on the other, will be discussed in the section upon the treatment of contracted pelves. 414 OBSTETRIC SURGERY. Operation.— When perforation has once been decided npon, there sliould be no delay in its execution. By delay, the very object of its performance— viz., the preservation of the life of the mother — is im- periled.* The patient should be placed in the usual obstetrical position, with the knees flexed and the hips drawn over the edge of the bed. Chloro- form is not requisite. It is useful, however, as a means of saving the mother from painful after-memories. There is no operation in obstet- rics in which the result depends so much upon thoroughness in carry- ing out antiseptic details. If the head is not fixed at the brim, it should be held firmly in position by the hands of an assistant, through the abdominal walls, or the child should be turned, and perforation per- formed on the after-coming head. Complete dilatation of the cervix is not essential to the execution of the operation. If the object is simply to relieve the maternal soft parts from pressure, perforation may be performed at an early stage of labor. When, however, it is intended to follow perforation by im- mediate extraction, it is necessary to secure sufficient preliminary dil- atation. In just this class of cases I have seen excellent results from the employment of Dr. I. E. Taylor's long, narrow-bladed forceps, which can be passed through a cervix dilated to scarcely an inch and a half in diameter. They enable the operator to seize the head and use it as a dilating wedge during and after a pain {vide p. 368). If the cervix hangs empty in the pelvis, and the head can not be moved from the brim, Barnes's dilators are often of great service. Unques tionably, in many cases le=!S violence is done to the mother if simple perforation is resorted to, the brain evacuated, and the dilatation of the cervix left to be accomplished by the pressure of the gradually collapsing head. This method, however, exposes the mother to the dangers of septic poisoning, as, unless the pains should be good and delivery rapid, decomposition of the foetus in utero speedily sets in after perforation. Instruments employed in Perforation.— Most of the perforating in- struments in use in this country are patterned,' with modifications, after the scissors of Smellie. Simpson's perforator is the one I have been in the habit of employing. As compression of the handles causes the separation of the perforating points, it can be easily managed with one hand. The projecting shoulders, just beneath the cutting por- tions, prevent the instrument from penetrating too far into the skull. The edges and points of the blades are rounded, so that they are not liable to injure the soft parts of the mother during the operation. The * Spiegelberg states that between the years 1870 and 1877, of thirty-three cases of perforation, three terminated fatally; while in the previous five years in which the operation was performed, at a late period, of thirteen cases, seven ended in death.

A better instrument is that of Monsieur Blot. It possesses Fig. 179.— Simpson's perforator. a spear-point, which makes it effective as a perforator.

Mechanically considered, Thomas's perforator is beyond reproach. It is, however, somewhat more difficult to keep in order than those previously mentioned. The basylist of Professor Alexander Simpson resembles in its gen- eral features the perforator of Dr. Thomas. It is, however, much Fig. 1S3.— Simpson's basylist. heavier and of more solid construction. In the place of the concealed knife it jDossesses two arms, which, when separated from one another, act as powerful levers. The instrument is designed not only to perforate the cranial vault, but, as its name implies, to break up the base of the skull. When this action is rendered necessary, the basylist should be pushed inward to the sphenoid bone, and a point selected for perforation in front of the sella turcica. After boring well into the Fig. 184.— Trephine perforator. sphenoid, the lever is used to forcibly separate the base into two por- tions. Ordinarily, the expulsion of the child can then be left to the natural forces. The Germans employ for the most part a long trephining perfo- rator, Avhich removes circular segments from the scalp and the skull. The trephine leaves behind no splintered portions of bones, and makes CRANI0T03IY AND EMBRYOTOMY. 417 an opening which is not likely to close from overlapping ; but it can, on the other hand, be nsed only upon the cranial vault. Previous to practicing craniotomy the bladder and rectum should be emptied. The operator introduces his middle and index fingers into the vagina, and presses them firmly against the most accessible por- tion of the child's head. Great care, at this stage, should be exercised Fig. 183.— Operation for perforating the child's bead. to gain an exact idea of the situation and the extent of the dilatation of the cervix. The operator then seizes the handle of the perforator in the right hand, and passes the pointed extremity, under the guid- ance of the fingei's of the left hand, to the region of the head at which it has been decided the perforation is to be made. If convenient, a suture or a fontanelle may be selected, in place of the bony table of the skull. The perforator should be pressed against the cranium with a boring movement until the cessation of resistance warns the operator that the bony incasement has been traversed. In cases where the skull is unusually thick or hard this part of the operation may prove a matter of some difficulty. Care should be taken to hold the instru- ment at right angles to the point of perforation, as otherwise it is apt to glance from the rounded surface of the head. 27 4^j^g OBSTETRIC SURGERY. If the head, in place of being fixed in the pelvis, is situated high up, every precaution should be taken in the operation. The head should be pressed firmly against the brim through the abdomen by an assistant. The perforator should follow the axis of the superior strait. The point selected for perforation should be near the symphysis, as the instrument is then much less liable to slip than if carried back- ward toward the promontory. The fingers of the left hand should keep constant guard upon its direction. Oftentimes, by way of pro- tection, the operator introduces the entire half-hand into the vagina. After the perforator has penetrated the skull, the opening should be enlarged by compressing the handles and separating the cutting blades; then, allowing the latter to close, the instrument should be semi-rotated, and a second cut made at right angles to the first. Be- fore withdrawing the perforator, it should be moved about freely to break up the brain-mass. The rapidity and completeness of the col- lapse of the cranial walls are, in a measure, dependent upon the com- pleteness of the evacuation of the cranial contents. Care, too, should be taken to pass the perforator into the foramen magnum to break up the medulla oblongata, and thus to insure the death of the child before delivery. Sometimes it is advantageous to wash out the brain-pulp by injecting a stream of water into the cranial cavity.* In face presentations care should be taken to pass the perforator through the frontal bones, or through an orbit. Where neither of these points is, however, accessible, it is possible to make the opening through the roof of the mouth, behind the nasal fossae. The perforation of the after-coming head is always a matter of considerable difficulty. The point of the perforator has to be inserted obliquely in place of at right angles to the skull, and therefore is more liable to glance. On theoretical grounds it has been recommended to insert the instrument either between the occiput and atlas, or through a lateral fontanelle. In practice, however, such niceties are rarely observed. , The operator simply passes the four fingers of the left hand under the, symphysis pubis, and, while the feet of the child are drawn dowuAvard and backward by an assistant, the perforation is made at any point behind the ear at which the manipulation can be most easily effected. Chailly recommends hooking down the chin of the child, and perforating, as in face presentations, through the roof of the mouth, f * Von Weber has shown that no cephalotribe can fully decerebrate a perforated head, in general only the small part of the brain being evacuated. lie has likewise demonstrated that a greater amount of compression can be accomplished in case of a fully than a partially decerebrated head.

Through CRANIOTOMY AND EMBRYOTOMY. 419 The trephine-perforator requires to be pressed firmly and steadily against the parietal bone. Sometimes, when a large scalp-tumor exists, it is necessary to make a preliminary incision through the integuments. The trephine is not liable to slip, and is easily managed ; as it can not be used either upon the after-coming head or in face presentations, and as it is difficult to keep clean and in order, the less complicated lance- pointed instruments have, however, enjoyed the preference in all coun- tries outside of Germany, Extraction of the Child after Perforation. — Formerly, after per- foration, a waiting policy was by many thought desirable. Osborne, indeed, recommended that at least thirty hours be allowed to elapse before delivery, in case craniotomy was performed upon a living child. The grounds for favoring a temporizing policy were found in the softening and relaxation of the sutures, and the ease with which flat- tening takes place after putrefaction has once set in. At present, however, it is customary to extract so soon as the condition of the os renders it safe to resort to the necessary operative procedures. This change in practice results from altered views regarding the dangers due to mere protraction of labor, to fear of septic poisoning, and finally to improved methods now at our disposal for the termination of labor. Extraction may be performed by the forceps, the cepha- lotribe, the cranioclast, the crotchet, or the blunt hook. In some cases version may be employed with success. Each instrument, each method, has its limitations and its range of applicability. Usually, in extreme disproportion, the operator finds it to his advantage to have at hand a complete equipment, and to resort at different stages of delivery to a succession of operative manoeuvres. The acceptance of single measures and the Avholesale condemnation of all others are cal- culated in difficult cases to lead to embarrassment and failure. A study, therefore, of the capacity of the various extractive instruments employed to deliver the perforated head is essential to the formation of correct judgment as regards practice. Forceps. — The use of forceps as an extractive instrument, after per- foration, is recommended by Tarnier as follows : " As the application of forceps has often succeeded in our hands, we do not hesitate to say that it is a good operation, applicable above all to cases in which the pelvic contraction is not considerable. The forceps possesses the ad- vantage of being in the hands of every physician ; it seizes the head firmly, and, by pressing the handles forcibly together, a sufficient evac- uation of the cerebral contents is effected to secure a marked flattening of the cranial walls. In making prudent tractions, one often succeeds the opening a silver catheter can be passed to the cranial cavity, and be used to break \ip the brain-mass, which should be washed out through the canal by injec- tions of water. — {Yide Ein neues Perforations Verfahren, Arch. f. Gynaek., Bd. vi, p. 505.) 420 OBSTETRIC SURGERY. in extracting the head withont any harm to the mother ; the danger begins only with too violent tractions." * These remarks apply, how- ever, to the powerful French forceps, which is capable of exerting con- siderable compressive force. Hodge has found his forceps useful under similar conditions.! The short handles and the great width between the blades, in the English forceps, render it useless as a tractor when craniotomy has been performed. CepJialofribe.— On the 6th of June, 1829, Baudelocque, le neveu, read before the Institut Royal de France a memoir upon a new method of performing embryotomy. J He first pictured the dangers incident to all operations effected with pointed and sharp-edged instruments introduced Avithin the uterus. From the statistics of the previous sixteen and a half years in the Maternite, he showed that half the mothers thus operated upon died, and that the shortest of these opera- tions lasted three quarters of an hour. He then described an instru- ment he had invented, which he termed the cephalotribe, and repre- sented that with it he could crush in an instant the base and parietes of the fetal skull, forcing the brain from the orbits, the nostrils, and the mouth, the integuments at the same time remaining intact and forming a sort of sac, which sufficed to prevent the edges of the fract- ured bones from inflicting injury upon the soft parts of the mother. The autlior furthermore expressed his conviction that the cephalotribe was destined to abolish and replace the perforator and the crotchet, and that it could be employed successfully in pelves measuring but two inches in the contracted diameter. This early instrument was two feet long, and weighed over seven pounds. In shape it resembled the forceps. To the handles a crank was attached, destined to aj)proximate the enormous blades to one another. The original cephalotribe has since been subjected to vari- ous modifications, with a view chiefly to the removal of its repulsive appearance. The observation of Chailly, in his Traite pratique des accouchements, 1843, that perforation should always precede cepha- lotripsy, led especially to the construction of lighter and more conven- ient instruments. The dream of Baudelocque, that the cephalotribe was destined to abolish the perforator, has never been fulfilled. The models in use at the present day vary considerably in weight, the extent of the pelvic and cranial curves, and the character of the apparatus for producing compression. These different varieties are simply expressions of the defective working of the instrument itself. The shape of the blades possesses the greatest importance practically. It is to be borne in mind that the cephalotribe is designed to act both as a crusher and as a tractor. Now, it so happens that whatsoever * Tarnier, Diet, lie Medecine et de Chirurgie, art.

Thus, it is evident that the greatest amount of crushing force is exercised when the blades run nearly parallel to one another ; but, without a cranial curve, the blades, in place of being applied to the convexity of the child's head, open like scissors, and thus are liable to slip, if the in- strument is employed as a tractor. Again, as the blades are usually applied in the transverse or in an oblique diameter, it is necessary to rotate the cephalotribe to make the flattened head correspond to the flattened pelvic diameter, liotation of the cephalotribe within the genital organs necessitates an instrument without pelvic curve ; and, yet, where there is any considerable projection of the promonotory, a straight instrument is apt to seize the head upon its posterior aspect only, and thus the head is often forced from the blades, when com- pression is used, like a cherry-pit, to use Cazeaux's simile, from between the fingers.

The instrument possesses a pelvic curve of two and three quarters inches. When the Scanzoni cephalotribe is 4.22 OBSTETRIC SURGERY. applied to the sides of the decerebrated head, the latter lengthens in the axis of the instrument, but Munde reports that he has witnessed the failure of the instrument to seize the head securely in the Wurz- burg clinic, in three cases out of four. Fig. 188 represents a cephalo- Fio. 188.— The author's cephalotribe. tribe made for me some years ago by Messrs. Tiemann & Co., which has met with considerable favor in New York and its vicinity. It has a cephalic curve of two inches and a quarter, measuring from the outer surfaces of the blades.* The pelvic curve is three inches and two lines in extent. These measurements are similar to those of the Prague instruments of Seyfert and Breisky. The blades are fenes- trated and grooved upon the inner surfaces. The advantages of an in- strument thus modeled are obvious. It is possible with its aid to seize the head when movable above the pelvic brim. As the points ap- proach each other closely after compression of the head is completed, the instrument becomes a perfect tractor, holding the head as securely as an ordinary forceps. Its construction is, however, virtually the abandonment of two favorite but chimerical ideas regarding the ca- pacity and mode of action of the cephalotribe, viz.. that it is capable of flattening the head so that the latter can be drawn through a pelvis measuring but two inches in the conjugate diameter, and that this can be accomplished by rotating the instrument, as we have mentioned, so as to make the flattened head correspond to the shortened diameter of the pelvis. The actual result of compression by means of the cephalotribe was long a matter of dispute. Baudelocque, with his ponderous instrument, claimed to have been able to instantly crush the skull, including the base. Kilian t relates that in his first case of cephalotripsy he succeeded in breaking up the skull by a single application into fifty-four pieces. Von Weber, however, made a large number of experiments upon still-born children, employing for purposes of com- * The advantages of making the blades parallel to one another are rather ap- parent than real ; for, however effectively compression with such an instrument may be applied, the head acts as a wedge, producing a separation at the extrem- ities proportioned to the absence of the cephalic curve. Breisky and Seyfert have insisted that it is better to transfer the greatest width between the blades from the extremities to the points at which they come into immediate contact with the child's head. \ KiLiAX, Organ f. die gesammt. Medeein, Bd. ii, p. 279. CRANIOTOMY AND EMBRYOTOMY. 423 parison instruments of various patterns, and found that in no case did he suc- ceed in fracturing the bones of the skull. Even after the complete evacuation of the cerebral contents the bones would bend, but did not fracture. The result was different, however, in cases where the cephalotribe was emploj-ed in actual labor, where the head was subjected at the same time to pressure from the uter- ine and pelvic walls. Under such circumstances the bones certainly may break, if they do not invariably. Fractures he found, in fact, less common than simple incurvations. Where a fracture took place in one bone it rarely extended to contiguous ones, and, in general, contributed but little toward the actual reduc- tion of the head. Winckel * presented three heads to the Obstetrical Society of Berlin, upon which the cephalotribe had been used to facilitate delivery. Com- pression, in these cases, had been employed in several diameters, and each time the cracking sound elicited could have led one to suj)pose tliat the bones were being reduced to small pieces, yet subsequent examination showed that only a single bone, and that, usually, according to the position of the head, a parietal bone, was broken to any extent, while the opposite side, generally the basis cranii, was but slightly ruptured. Now, the greatest amount of compression effected by the cephalotribe does not exceed two to two and a quarter inches. The bizygomatic diameter, indeed, which measures three inches, is not, in or- dinary cephalotripsy, attacked at all.t It has always been objected to the cephalotribe that its application in the transverse diameter increases the length of the head in the antero-posterior diameter, or precisely where the pelvis is the narrowest, and thus adds to the difficulty of delivery. This is no doubt true when the head is fixed in the pel- vis, a fact which should lead us to give the preference to other instruments for extraction after engagement has taken place. Above the brim, the cephalotribe seizes the head usually in an oblique diameter, so that the compensation takes place in the opposite oblique diameter. If the head is seized in the transverse diameter, it may easily be rotated into an oblique diameter. Sometimes the compressed head rotates spontaneousl}', so that the cephalotribe comes to oc- cupy the conjugate, a thing obviously possible only in moderate degrees of contraction. Artificial rotation of the cephalotribe into the conjugate is dan- gerous, and should under no circumstances be attempted. It must be borne in mind that the axis of the instrument is in a line between the upper border of one blade and the lower blade of the other, and not in one drawn transversely between them. If spontaneous rotation occurs, the instrument should be re- moved, and the cranioclast employed as a tractor. Extraction with a powerful' instrument like the cephalotribe can not be safely undertaken when the points of pressure from the blades are the soft tissues between the symphysis and prom- ontory. Thus we find the cephalotribe useful in compressing the head before it becomes fixed at the brim. It is, moreover, advantageous as a tractor in moderate degrees of pelvic contraction. With two and three quarters inches in the conjugate, the limit for its safe employ- ment is, as a rule, reached. Of course it is understood that other factors than the pelvic diameters may influence the result. Thus, * Winckel, Kephalotripsie, Monr.tsschr. f. Geburtsk., Bd. xxi, p. 81. f Fritsch, Der Kephalothryptor und Braun's Cranioclast, Volkraann's Samml. klin. Vortr., No. 127, p. 870. 424 OBSTETRIC SURGERY. much dej^ends upon the size of the child's head, the resiliency of the cranial bones, and the relations of the pelvic diameters to one another. It is not disputed that the cephalotribe is capable, if force is used, of accomplishing delivery through a smaller space than the one given ; but the severe injuries to the maternal tissues which the instrument is apt to inflict, even when every caution is exercised, make its employ- ment dangerous in the higher degrees of pelvic deformity. In 1863 Pajot * published a paper in which he stated that, while in cases of distortion in which the narrowing did not exceed two and a half inches cepha- lotripsy was a favorable operation, requiring the exercise of no great amount of force, and but two or three applications of the instrument, below that point he regarded it as nearly as dangerous as the Cajsarean section. In the belief that these results were due to rude attemjits to drag an imperfectly reduced head through the contracted space, he proposed that in all cases below two and a half inches no tractions should be made, but, so soon as dilatation had ])roceeded far enough to permit, perforation should be performed, whereupon complete dilata- tion would occur more speedily, and cephalotripsy might be begun at an early period of labor — a point in itself of considerable importance. While applying the cephalotribe, one or two assistants should make counter-pressure over the pubes to steady the head. The blades should be introduced as high as possible by depressing the handles. After compressing the head, rotation, if it has not occurred spontaneously, should be cautiously attempted. The slightest obstacle should, however, be the signal for suspending rotation and withdrawing the instrument, when Nature usually brings about rotation with astonishing ra- pidity The instrument should then be reapplied, and the compression re- peated. The same process should be gone through with a third time, after which the woman should be placed in a convenient posture and given bouillon to drink. Then, governed by the state of the pulse and the general appearance of the patient, the quiet or excitement manifested, the weak or energetic char- acter of the pains, the cephalotribe should be applied two or three times every two, three, or four hours, leaving the expulsion of the foAus entirely to Nature. M. Pajot has never found more than four applications of this procedure neces- sary, while one or two have generally sufficed. After the passage of the head, one or two applications of the instrument are required, as a rule, to reduce the thorax. To be successful, however, it is requisite that the operation should be resorted to at an early period of labor, when, as a rule, not more than six to eighteen hours are needed for Nature to expel the uterine contents. Tractions should be employed only in those cases to which one is called at a late period, after the powers of Nature are exhausted. Objections to this plan of Pajot have been made as follows : That there is risk of rupture of the uterus from the pro- longation of the labor; that the uterus is exposed to injury from the spiculai at the point of perforation; that, owing to the great rapidity with which decompo- sition takes place after cephalotripsy, the bones of the skull are liable to become denuded of their coverings; and, finally, that after a given period the mem- branes become so far destroyed as no longer to protect the uterus from its de- composing contents. Pajot replies by adducing seven cases in which he em- ployed his method. Five of the cases were successful, and two terminated * Pajot, De la cpphalotripsie repetec sans tractions, Paris, 1863. CRANIOTOMY AND EMBRYOTOMY. 425 fatally. The highest degree of deformity for which he operated was a case in which the contracted diameter was something less than an inch and a half. The patient died from ruptured uterus, due, according to M. Pajot, to attempts made previous to his arrival to perform cephalotripsy with a badly constructed instrument. The application of the cephalotribe does not differ from that of the forceps. AVhere perforation lias been performed, spicule of bone should be carefully removed with the fingers. Confirmatory evidence as to the direction of the head may be obtained by exploring the cra- nial cavity with the finger, as, in this way, the exact position of the base and vault may be determined. Great caution should be exer- cised during the introduction of the blades not to injure the vaginal or uterine tissues. It is not always easy to lock the instrument after the blades have been adjusted. The left blade is easily placed, but often the right blade is with difficulty brought forward to the cor- responding transverse or oblique diameter. Compression should be made slowly, and the opening made by the perforator should be care- fully guarded lest cutting portions of bone protrude. Extraction should take place under the guidance and protection of the fingers of the left hand. Sometimes the cephalotribe is used to compress and extract the after-coming head in cases of moderate pelvic contraction. Under such circumstances perforation is usually not a prerequisite. The cephalotribe seizes the head securely, and acts with great power upon the basis cranii. The increased diameters of the head accommodate themselves more readily, too, to the long diameters of the pelvis than in cranial presentations. When the head is retained in the uterus after it has become detached from the body, it should be held by an assistant through the abdominal Avails, and steadied by a crotchet in- troduced into the foramen magnum, or fixed into an orbit, or in the lower jaw. The cephalotribe may then be applied to complete the ex- traction. Cranioclast. — It is necessary to distinguish between two instru- ments, each of which bears the name of cranioclast. The original model was the device of Sir J. Y. Simpson, and was intended by him to replace the cephalotribe. It is substantially a powerful pair of craniotomy-forceps. The larger blade, which is intended to be placed upon the outer surface of the head, is fenestrated and grooved. The smaller one, for introduction into the perforated skull, is solid, and supplied with ridges which fit into the grooves upon the opposite blade. The two blades articulate by means of a button-lock. By a twisting movement, the cranioclast, when applied, can be employed to wrench off the bones of the calvarium, different portions of the skull being seized successively with the view of accomplishing that result. As the fractured bones are covered by the scalp, they are prevented 426 OBSTETRIC SURGERY. from inflicting injury during the subsequent course of delivery. But the cranioclast is not only of use in breaking up the cranial vault, it is likewise the most effective of all the instruments employed for extrac- tion of the perforated head. The principal defect of the Simpson cranioclast is that it attempts to combine in the same instrument the functions of crusher and tractor. Now, as in the ceph- alotribe, the devices which make it the most effective instrument in the one di- rection weaken its utility in the other, Braun's modified cranioclast is intended to serve purely as a tractor. All idea of its undertaking to break up the skull is discarded. The work of compression and disarticulation is left to the counter-press- ure of the pelvic walls, and to the em- ployment of craniotomy-forceps and the cephalotribe. The term cranioclast is therefore a misnomer. Munde's proposed substitute of " craniotractor " is descrip- tive of its real action. Yet the modifica- tions of Braun were as simple as they have proved appropriate. A pelvic curve has been given to the blades ; the handles have been lengthened so that the lock, even when the instrument is introduced high up, is outside the vulva ; and, finally, an apparatus for compression has been added. The advantages of Braun's cranio- clast over its rival, the cephalotribe, are as follows : it is of comparatively small size ; again, one branch lies inside the head, in a space not otherwise occupied; the outer branch imbeds itself in the soft coverings of the head, and thus is pro- After a few tractions the cranioclast occu- pies the middle of the pelvis, where it can be so guarded by the hand that it need not even come into contact with the vaginal walls ; as the head is drawn into the pelvis, the pressure is not concentrated at one or two points, bat is diffused over the entire pelvic rim ; the head is therefore able to mold itself to the shape of the pelvis. Subsequent to the use of Braun's cranioclast, extensive lacerations and injuries to the maternal organs are rarely found. The cranioclast takes firm hold of the head. It never slips during extraction. It is not apt to tear Fig. 189.— Simpson's cranioclast. tected from doins harm. CRANIOTOMY AND EMBRYOTOMY. 427 away when the cranium and scalp are seized together. The most secure grip is obtained when the inner blade is passed to the base of the skull, while the outer one is applied to the face or over an ear. Fig. 190.— Braun's cranioclast. Should the portion grasped tear away, the readjustment of the instru- ment upon another part of the skull is easy. Thus, the inner blade can be turned, of course, in any direction without difficulty, while the Fig. 191.— Head of child after delivery with the cranioclast. (Simpson.) outer blade is easily disengaged from the scalp-tissues and changed in its position by direct pressure from the fingers and slight leverage movements of the handle. The cranioclast may often advantageously be used as a tractor in 42S OBSETRTIC SURGERY. cases where the head has been previously crushed and flattened by the cephalotribe ; but, where extraction with the hitter is rendered difficult by slipping, or by the inability of the operator to make the altered diameters of the head correspond to those of the contracted pelvic space, the immense superiority of the cranioclast consists in the capa- city to seize the head antero-posteriorly, and thus to bring its length- ened diameter into the transverse space of the pelvis. The cranioclast enables us to extend the limits of safe delivery far beyond what would be admissible with the cephalotribe, as with its aid it is possible, after the partial or complete removal of the flat bones of the skull, to tilt the chin downward, and draw the base by the edge through the conjugate. In this way craniotomy may be resorted to in pelves measuring less than two and three fourths inches antero-pos- teriorly. Indeed, Barnes claims that one inch and three fourths in the conjugate and three inches in the transverse diameter furnish sufficient space for a successful operation.* The proceeding to be pursued in these difficult cases is as follows : After perforation introduce a forceps-blade under the scalp, and detach the latter as far as possible from the cranial bones ; break up and wash out the entire brain-mass ; seize the parietal bones beneath the scalp with a good pair of craniotomy-forceps,f and break them away piece- meal by a twisting movement of the wrist. The withdraAval of the fractured bones is always a matter of delicacy. Unless the soft parts are carefully guarded by the hand, the maternal tissues are apt to be cut and lacerated by the sharp edges and splintered corners of the bones. Skene J has found it a great aid, in some cases, to use a large-sized Sims speculum to bring the head into view, and to go through the various steps of craniotomy with the guidance of the eye. The sug- gestion is an excellent one ; but when the head is high up, as is the rule in difficult cases, I have not always found it practicable to expose in this way the presenting part. Horwitz * recommends, in difficult cases of the unexpanded cervix, to perforate through a large Fergusson speculum. After the removal of the parietal bones, the fenestrated blade should be placed under the chin, or in the mouth, while the smaller one is in- troduced inside the perforation, and applied so that the frontal bones are included in the grasp of the instrument. The blades should then * Barnes, Obstetric Operations, p. 402. For discussion of this point, see Treat- ment of Contracted Pelves. t Meigs's craniotomy-forceps has been largely used in America, and may be confidently recommended. There are two forms, one straight and the other curved. Dr. Taylor's modification consisted chiefly in increasing the length of the instru- ment, so as to render it more available in operations at the superior strait. t Skene, Trans, of the Am. Gyna;c.

As the distance between the orbital plates and the chin, including the instrument, does not exceed Fig. 19^. — Meigs's crauiotomy-forceps (modified by Professor I. E. Taylor). two inches, and the width of the base is only about three inches, !t is evident that, in skillful and experienced hands, this method is capable of almost indefinite extension. After delivery of the head, the extraction of the body may still cause difficulty. If, then, through an opening made with a perforator between the clavicle and shoulder-blade the smaller blade be intro- duced, and the outer blade be applied on the back, so that the two in- clude the spine, the cranioclast will seize the trunk firmly, and is capa- ble of exerting great force as a tractor. Crotchet and Blunt HooTc. — As tractors, neither of these instru- ments is much in vogue at the present day. It is well, however, to become familiar with their uses, as we are not always placed where we can have a complete armamentarium at our disposal. Fio. 193.— Crotchet. The crotchet is a steel hook, with a sharp-pointed extremity. The shaft is either straight or curved to adapt it better to the convexity of the head. In craniotomy the instrument is often useful in breaking up the brain. It may be inserted into an orbit when it is desired to 430 OBSTETRIC SURGERY. bring tlie base of the skull end on into the pelvis. In default of either cranioclast or cephalotribe, it may be employed to extract the perfo- rated head. To this end it should be passed through the opening and its point inserted into one of the bones of the cranial vault. Two fin- gers of the left hand are then passed to the outer surface of the skull, to serve as a guard and to make pressure against the point fixed upon the inner surface. If much resistance is met with, the part is apt to tear away, and a new hold has to be taken. When portions of bone are broken away they should be removed with the fingers, to prevent their doing harm. The process is often tedious, and in unskillful hands is not devoid of danger. When the bones of the vault yield under trac- tion, a more effective grip may sometimes be obtained by fixing the crotchet at the foramen magnum or the sella turcica. Or, in place of introducing the instrument into the skull, it is sometimes inserted outside, behind the ear^ into the mastoid process, or into the occiput, near the foramen magnum. The blunt hook, though not indispensa- ble, is capable of rendering valuable service in delivering the head after the performance of craniotomy. Dr. I. E. Taylor gives the preference Fig. 194.— Dr. Taylor's right-angled blunt hook. to a right-angled instrument. The blunt hook can not, of course, be at- tached to flat surfaces of bone. It may be used, however, to draw down the chin, or it may be thrust into an orbit. Where perforation has been made upon the after-coming head, the blunt hook may be introduced through the opening and traction made directly upon the base of the skull. In difficult cases, delivery of the trunk is sometimes favored by tractions made by a blunt hook inserted under the posterior shoulder. Fer^io;^.— Version, with extraction by the feet, with or without cephalotripsy, has been warmly commended by Bertin, Tarnier,* and Taylor,t while it has been condemned in harsh terms by others. AVhere it is practicable to perforate and turn early in labor, at a time when version is easy, the method has the advantage of bringing the longest diameter of the head into correspondence with the long diameter of the pelvis, and favoring the molding of the head to the shape of the canal it has to traverse. At the same time it avoids the dangers of contusing the soft parts incident to the use of the cephalotribe. Dr. Taylor recommends combining propulsion above the pubes with trac- tions made upon the extremities. * Tarnier, Diet, de medecine et de chirurgie, art. Embrvotomie, t. xii p 668 + Taylor. What is the Best Treatment in Contracted Pelves ? Trans, of the Aew York Acad, of ]Med., 1875. CRANIOTOMY AND EMBRYOTOMY. 431 Great ingenuity has been exerted to devise some good way to overcome the difficulty which grows out of the defectiveness of the preceding measures in acting directly upon tlie base of the skull. Cephalotomy,* or the removal of the head by segments, has been pro- posed as a substitute for perforation and cephalotripsy. Van Huevel's forceps-saw divides the head from crown to base into two halves. Tarnier's forceps-saw removes from the head a triangular segment, the apex of which is cut from the skull-base. Dr. Barnes f has suggested the application of Braxton Hicks's wire ecraseur to successive portions of the head. Hubert's transforaieur is designed to bore through the sphenoid, and thus to destroy the re- sistance of the base. The sphenotribes of Valette, Hiiter, and the Lollines, are a combination of the cephalotribe and the transfarateur. Notwithstanding the principle of cephalotomy is mechanically correct, the operation has never met with any general acceptance, partly owing to the high price and complicated structure of most of the yig. 195. — Segment re- instruments required for its performance, ^d perhaps in nier*^'^forceps*'- Sw part to the fact that, in the higher degrees of pelvic de- (P- Thomas.) formity, where their advantages over the more familiar methods would be theoretically most complete, the bulky nature of the forceps- saws and the sphenotribes interfere with their employment. Tlie favorable reports made by their inventors of the results they have personally obtained render, however, a reference to the subject necessary. Embkyotomt. In a literal sense, embryotomy includes all the graver opera- tions designed to diminish the volume and resistance of the foetus. Custom has, however, restricted the term to those operations only which are performed upon the trunk of the child. It is used, there- fore, as a rule, in contradistinction to craniotomy, and not in its ge- neric sense. Indications for Embryotomy. — 1. In extreme degrees of pelvic con- traction, where the size of the body obstructs delivery.J 2. In fetal malformations, with abdominal enlargement due to pathological con- ditions of the more important viscera, and in cases of extraordinarily developed children. 3. In neglected transverse presentations, in which version is impossible, or at least can not be performed without en- dangering greatly the life of the mother. * Tarnier, Diet, de Medeeine et de Chirurgie, art. Embryotoniie, p. 680. f Barnes, Obstetric Operations, p. 411. X It has been said that, in cases which do not demand the Ciesarean section, this indication is not likely to arise. In the extraction of the child's body, however, through a small justo-minor pelvis, which required for its completion upward of twenty-five minutes, post-tnortem examination showed more extensive disturbances from arrested pelvic circulation, due to compression from the child's body, than from the lesions arising out of the performance of craniotomy. 432 OBSTETRIC SURGERY. Embryotomy includes two operative measures, viz., exenteration and decapitation. Exenteration.— By exenteration we mean the opening of one of the large cavities of the trunk and the removal of the contained viscera. It is most commonly indicated in transverse presentations, where de- c.ipitation is not easy to perform, as in cases of extreme pelvic con- traction with the head high up above the pelvis. The opening may be made by means of a pair of curved scissors or the ordinary perforator. The same precautions against injury of the maternal tissues have to be observed as in craniotomy. In shoulder presentations an assistant should press the fundus of the uterus downward. The operator at the same time thrusts the perforator, or the scissors, between the ribs, and then enlarges the opening by turning the instrument so as to make a second incision at right angles to the first. Next, splintered portions of bone should be carefully broken away wdth the fingers, until the opening becomes sufficiently extensive to permit the introduction of the half-hand. In tearing awJly the viscera, the fingers may, if neces- sary, be aided by the volsella-forceps. The abdominal cavity may be reached directly through the thorax by perforation of the dia- phragm, or a fresh opening may be made through the abdominal walls. After evisceration, the reduced bulk of the child renders it pos- sible to proceed directly to seize the feet and perform version. This method is, however, generally difficult, and endangers the distended cervix and lower uterine segment. If, therefore, the shoulder is high up, the breech, which is easily reached, should be drawn down with the fingers or the blunt hook, in imitation of the mode of delivery in spontaneous version. When, however, an arm presents, and the shoul- der is crowded into the pelvis, the child may be drawn through doubled upon itself, as in spontaneous evolution. Decapitation. — Whenever, in neglected transverse presentations, the neck can be easily reached, decapitation furnishes the simplest and mildest plan for overcoming the difficulties which prevent delivery. Fig. 196.— Braun's decapitating hook. Decapitation may be effected in a number of different ways : 1. Draw upon the prolapsed arm to bring the neck well down and within reach. Pass the finger or a blunt hook around the neck, and CRANIOTOMY AND EMBRYOTOMY. 433 then, carefully guarding the points, divide with a strong pair of scissors by a series of short movements the soft structures and the vertebral column. 2. In many cases the division of the neck can be advantageously accomplished by Braun's decollator. This in:^trument is a modifica- tion of the blunt hook. The terminal portion is, however, bent at nearly an acute angle. It is likewise flattened from side to side, and ends in a button-shajDed extremity. The handle is fixed at a right angle, and is capable of im- parting to the instru- ment powerful leverage movements. In em- ploying the decollator, the index and middle fingers of the left hand should encircle the child's neck from be- hind, while the thumb is placed upon the an- terior surface. The neck should then be firmly grasped and drawn down into the pelvis as far as jdos- sible. The decollator should be passed up flat under the sym- pliysis pubis along the thumb of the opera- tor, until the button- end has advanced far enough to be turned to the rear over the neck. Finally, the in- strument should be seized by the handle with the right hand, and rotated to and fro, while tractions are simultaneously made in a down- ward direction. It is surprising how quickly, as a rule, the spinal column may be divided by this manoeuvre. After the separation of the vertebrae, care must be taken not to draw down with too much force, lest the integuments and soft structures yield suddenly, and violence be done by the rapid withdrawal of the instrument. This accident may be avoided by using moderate tractions and dividing the last remnant of the tissues with a pair of scissors. The decapitating 2S FiQ. 197.— Braun's method of decapitation. 434 OBSTETRIC SURGERY. hook of Ramsbotliam, which is curved, and has a cuttiug edge upon the concave part, is more difficult to apply, and is a less safe instrument in unskillful hands. 3. Pajot originated an ingenious method of decapitation, which, in default of special instruments, is capable of rendering valuable service. It consists in passing a strong cord around the child's neck, and, by a sawing movement, cutting through the parts. The vagina should be protected by a speculum from the friction produced by the to-and-fro movement of the string. The chief difficulty of the operation lies in getting the string around the neck. Pajot caused a groove to be made upon the concave surface of the blunt hook which forms a constant attachment to one of the handles of the ordinary French forceps. Through this groove he passes a string, to the end of which he fastens a round lead bullet ; when the blunt hook is adjusted about the child's neck, the weight of the bullet draws the cord downward so that it can be reached by the hand of the operator. Dr. Kidd recommends attach- ing a string to an elastic catheter armed with a strong stylet ; then, »fiAy\fW(> » Fig. 198.— Embryotome of P. Thomas. after imparting to the instrument the proper curve, it should be passed around the chdd s neck, and, as it is withdrawn, the string should be used to drag a strong cord or the chain kraseur into place Still more ingenious is the embryotome of Pierre Thomas, consist- ing of two blades modeled after a somewhat expensive instrument de- vised by M. larnier. The curved blade should be passed posteriorly opposite the sacrum. The straight blade should be introduced in front directly beneath the pubic bones. When adjusted, the extremities of CRANIOTOMy AND EMBRYOTOMY. 435 the blades are in apposition. Both blades contain a grooved canal. A piece of whalebone armed with an ivory knob is then introduced into the canal of the straight blade, while a long, flexible piece of whale- bone provided with an ivory ring is passed into the canal of the posterior curved blade. The descent of the posterior whalebone fur= Fig. 199.— Embrj'otome adjusted around the neck of the child. nishes the evidence that the canals of the two blades are in apposition^ and that the longer piece has entered the posterior canal. When the circuit is completed, a loop of cord is passed through an eyelet in the end of the whalebone, and serves as an attachment to a chain-saw, which, as it is drawn upward, leaves the groove and encircles the child's neck. In decapitating the child by a to-and-fro movement, the soft parts are protected by the blades of the embryotome. ^3g OBSTETRIC SURGERY. CHAPTEK XXIII.

The Cesarean Section. The term Ccesarean section is applied to cases in which the foetus is removed from the mother by au incision made through the abdomi- nal and uterine walls. Although the operation pretends to great antiquity, the earlier his- tories are probably of mythical origin. The supposed references in the Talmud are, according to Rodenstein, mistranslations of the text. The same authority suggests that even the lex regis, attributed to Numa Pompilius, which makes it obligatory upon the physician to remove the child by abdominal section in case the mother dies during pregnancy, was really added to the Roman law in the middle ages, with the intention of giving force to the decretals of the Church, which sought, through the Caesarean section upon the dead, to rescue the child for the rite of baptism before its life became extinct. During the sixteenth century there seems no reason to doubt the authenticity of certain cases of laparotomy, performed during the life of the mother, for the removal of the foetus in extra-ut3ri.i3 pregnancies. In 1581 Francois Rousset* published the historias of fourt3en successful Caesa- rean sections, six of which were said to have been performed upon the same individual. These cases were repeated from hearsay, and from accounts taken from letters written by friends. Their genuineness was challenged at the time of publication by the opponents of the operation, and they are now generally regarded as resting upon ques- tionable authority. The first operations mentioned after the publica- tion of Rousset's work are said to have proved fatal. The earliest well- authenticated record of Cassarean section conies to us from Germany. It was performed in Wittenberg, by Trautmaun, in IGIO. The patient lived from the 21st of April to the IGth of May. Scarcely any doubt was entertained of her recovery, when she was suddenly seized with a fainting-fit and died, contrary to all expectation, in about half an hour. Until a very recent date the Caesarean section was Justly regarded as one of the most hazardous operations in surgery.

Mayer* gathered 1,605 cases, with 54 per cent recoveries. Pihan-Dufeilhay f collected 88 cases, published be- tween 1845-'49, of which 57 per cent ended in recovery. Dr. Harris (1888) gathered with great industry the histories of 153 cases per- formed by the older methods in the United States, 56 of which, or nearly 37 per cent, ended in recovery. Under this showing it will be seen that at best fully one half of all the Ctesarean operations ended fatally. Spaeth, writing before the conservative operation of Siinger had changed the results of practice, said that there had not been a single case in the lying-in hospital in Vienna during this century in which the mother had survived. Baudon, writing in 1873, said, " In Paris there has not been one successful case in eighty years, though in the present century the operation has been performed on perhaps as many as fifty women." The responsibility for these results was due, in the first place, to septic infection, the evils of which were especially experienced in hos- pital practice, and to the postponement of the operation until death impended. What was possible after eliminating these elements of danger even with barbaric methods of surgery, was shown in a rejiort by Harris, J in which he gave the history of nine women whose wombs had been ripped up in advanced pregnancy by the horns of infuriated cattle, with the survival of four women and four children. Again, in six cases of self-inflicted Caesarean section, five of the women re- covered. Of hardly less importance in blocking progress was the persistent superstition that the alternating contractions and relaxations of the uterus forbade the employment of the uterine suture; Consequently, the uterine incision was left to gape, and closure in favorable cases was usually effected by an adhesive inflammation which united the uterine to the abdominal walls. According to Sanger, only one instance is known where complete union took place throughout the length and depth of the wound. Sometimes cicatricial tissue extended the length but not through the thickness of the incision, and was of a callous consistency ; in others the line of union was at points of extreme tenuity, disposing to hernial protrusions, and in subsequent pregnan- cies to rupture ; while in others, again, union took place at intervals only, with the formation of fistulous' openings, communicating with the abdominal walls, or with circumscribed cavities in the abdominal inclosure. Yet so strong are old prejudices, that even recently Porro's proposition to avoid the risks of the gaping of the uterine wound by * Mayer, notice by Bromeisl, Wien. med.

Obst, July, 1887. ^3s OBSTETRIC SURGERY. the removal of the entire uterus, was accepted as a surgical necessity. Indeed, it has been in this country chiefly, where tradition exerts a feeble influence, that prior to the appearance of Sanger's exhaustive monoo-raph the suture enjoyed anything like a fair trial, and Sanger strongly re-enforced his argument in favor of its employment by the successes obtained through its agency by Polin, Brickell, Jenks, and Lundgren. The improved Cajsarean section of the present day is based upon an early resort to the operation before the patient's strength is ex- hausted by lengthy labor and the futile resort to measures to extract the child by the natural passages ; upon the complete closure of the uterine wound, and upon the employment of aseptic precautions, such as are commonly used in abdominal surgery. Sanger is justly regarded as its founder, for though others, and notably Harris, in this country, had insisted upon the importance of the same factors, the great body of the profession was still engaged in the task of showing that the Ctesarean section had profited nothing by the recent advances in surgi- cal science when Sanger's work * was published. The latter at once awakened the dormant interest of the profession on the subject. Its challenge to test the question of the practicability of the Csesareau operation, as modified by modern principles, met with a ready re- sponse, and the triumphant reinstatement of the measure in the do- main of legitimate surgery followed. Since then the. mutilating oper- ation of Porro has been restricted within narrow limits, and the croak- iugs of the anti-Coesarean school are no longer heard. Indications for the Caesarean Section. — As even the improved Caisarean section is a hazardous operation, its performance is chiefly justifiable in cases in which craniotomy and the delivery of the child by the natural passages involve the life of the mother in still greater peril. It is indicated, therefore, in extreme degrees of pelvic contrac- tion, in the case of solid tumors which encroach upon the pelvic space, and in advanced carcinomatous degeneration of the cervix. The Caesarean section is permissible if the mother is moribund and the cliild is known to be alive, where rapid delivery by the natural passages is impossible It may be undertaken at the mother's request if otherwise delivery can not be accomplished without the sacrifice of the child. If in any case the decision is left to the physician, he should regard the welfare of the mother as of paramount importance. It has been said that if a woman, knowing herself to be incapable of bearing living children, exposes herself to the repetition of pregnancy, it becomes the duty of the physician to perform the Cesarean section in the interest of the child. The duty of the physician is, however, * Sanger, The Ca?s.arean in Cases of Uterine Fibromata ; Criticisms, Studies, and Propositions for the Improvement of the Caesarean Section. CiESAREAN SECTION.— OPERATIONS OF THOMAS AND PORRO. 439 to his patient. He is not -to constitute himself either judge or exe- cutioner. Operation. — The success of Caesarean section depends in large measure upon the control which the obstetric surgeon possesses over the conditions under which the operation is performed. When it is practicable, the patient should be prepared for the operation by full baths, by disinfecting vaginal douches, by laxatives, by diet, and by tonics. The most suitable time to operate is after dilatation has begun, but previous to the rupture of the membranes : after dilatation, because it is desirable to provide a free outlet for the uterine discharges subse- quent to the operation, and because the retraction of the uterus after delivery, which furnishes the most efficient means of controlling hemorrhage from the uterine wound, is best secured if the operation is performed at a time when the contractions are strong and frequent ; previous to rupture, because there is then greater probability of finding the child alive and the maternal tissues uninjured. Unless, too, the head or breech protrudes spontaneously through the incision made in the uterine wall, the delivery is much more readily performed while the membranes are iutact than after the uterus has retracted firmly down upon the child's body. The necessary preparations should meantime be made, and selected assistants should have explained to them their respective duties. There should be one assistant to take charge of the anesthesia, one to hold the uterus after it has been turned out of the abdominal cavity, one for the instruments, one to take charge of the newborn child, and, if still, to aid in its resuscitation, and a trained nurse to wash and keep account of the sponges. Few instruments are required. The entire armamentarium should consist of one or two scalpels, a pair of blunt-pointed scissors, a half- dozen compression forceps, a needle-holder, curved needles, an irri- gator, a powder-blower, aseptic towels, and vessels containing an abun- dance of warm carbolized water. The sponges should be aseptically cleaned* and carefully counted. A piece of rubber tubing will be needed to place around the lower uterine segment to control the hem- orrhage when the uterus is incised. For ligatures, silver wire, silk, and catgut have each their advocates. At present silk is favored by Sanger, Kelley, and others, as the preferable material — a choice in which I personally concur. At the time of operation instruments, sponges, » * To render sponges aseptic they should first be boiled in a weak solution of soda, and washed out in boiled water. They should then be soaked for two hours in a solution of permanganate of potash (1 : 4,000), and. after repeated washings in a four-per-cent solution of hyposulphite of soda, to which three to four per cent of muriatic acid has been added, should be preserved in a five-per-cent solution of carbolic acid. Zweifel, Arch. f. Gyn., vol. xxxi, p. 204. 440 OBSTETRIC SURGERY. wire, and silk sliould be jilaced in a two-per-cent solution of carbolic acid. The operator and bis immediate assistants should thoroughly wash their hands and forearms with soap and water. The nails should be cleaned with a nail-brush and nail-cleaner, and, after removing sapona- ceous materials with alcohol, the hands and arms should be bathed for several minutes in 1 : 1,000 solution of corrosive sublimate. During the operation clean white aprons should be worn. Preliminary to the operation the patient's bowels and bladder should be emptied, and the vagina should be douched with a five-per- cent solution of carbolic acid. During the induction of angesthesia pains should be taken to make sure that the auscultiitory signs of foetal life are present. After the patient has been placed upon the table the pubes should be shaved, and the abdomen should be cleansed in the usual manner with soap-suds, corrosive- sublimate solution, and ether. The abdominal incision should be made to extend from a point above the pubes to one, three, or four inches above the navel. At this stage it is convenient to pass a half-dozen long wire sutures through the upper portion of the incision. For the moment the ends should be left free. The child can be removed from the uterus in situ, in which case an assistant should take pains to keep by external pressure the abdominal walls in close contact with the surface of the uterus ; but it is a great convenience first to turn the uterus out of the abdominal cavity. This is accomplished without much difficulty, by first tilting the uterus so as to cause it? left border to present at the incision, and then pressing the abdomiail walls backward over the uterus. As it emerges the assistant should envelop it in a warm carbolized towel, and hold it at nearly right angles to the abdomen. The operator now tightens the sutures in the abdominal incision to retain the intestines, and places a flat sponge beneath the abdominal walls behind the uterus to prevent the entrance of fluids into the peritoneal cavity. The rub- ber tubing should be placed loosely around the lower uterine segment beneath the presenting part, or, where there are plenty of assistants, manual compression applied to the cervix may be employed to control hajmorrhage. I prefer, instead of beginning at the fundus, by a series of rapid strokes first to make a small incision down to the membranes m tlie median line just above the lower segment, and then to extend the incision rapidly upward with a pair of blunt-pointed scissors. If the placenta is encountered, it should be detached with the fingers and pushed to one side. The uterine incision should be between four and five inches in length. If the membranes are intact, they should be rupt- ured and the child should be rapidly extracted. The rubber ligature should be tightened, if necessary, to control bleeding. As the uterus retracts, the assistant sees that the abdominal incision is kept in close CESAREAN SECTION.— OPERATIONS OF THOMAS AND PORRO. 441 contact with the uterine surface. AVith a little care no blood or fluid need obtain entrance into the abdomen during the entire operation. In many cases the membranes peel off intact with slight traction, and come away with the placenta. Adherent portions of decidua should be carefully detached with the fingers. I have found it easy to wash out the uterine cavity with a disinfectant fluid, by placing the irrigator nozzle in the wound and pressing the cut surfaces together while loosening for the moment the elastic ligature. The pressure of the hands prevents hfemorrhage, and the stream passes out unimpeded through the vagina. When this has been done the uterine cavity should be sponged nearly dry and the inner surface powdered over with iodoform by means of an insufflator. The uterine incision should be closed by two sets of sutures, a stronger one of wire, silk, or catgut for the muscular strvictures, and a fine one of silk or catgut to approximate the peritoneal borders. The muscular sutures should be introduced one half inch from the borders of the incision, and passed obliquely downward to, but not including, the decidua. Of these, eight to twelve are usually necessary. For the peritonteum I have used an interrupted suture of fine silk, and have employed with great satisfaction the Lembert stitch to secure close union. Leopold advocates catgut for both deep and superficial sutures, on the ground that they produce less subsequent irritation ; but care must be taken to secure catgut of good quality, and to tie the deep sutures with three knots. After the suturing is completed a hypodermic injection of the fluid extract of ergot should be made into the skin of the outer surface of the thigh. The elastic ligature should then be loosened, and manual compression maintained until firm contractions have been secured. After replacing the uterus, the abdominal wound should be closed without haste, and with punctilious care. A full antiseptic dressing should be applied. The patient, finally, should be placed in bed with hot bottles around her, and, in case of failing heart-action, the usual restoratives should be applied. As vomiting after the Cassarean section is rare, the administration of liquid food by the stomach is possible almost from the first. Tym- panites is sometimes distressing, but can often be relieved by injections of soap-suds in chamomile infusion, while in severer cases a calomel laxative may be administered (gr. ijss every five hours until action is produced). The abdominal stitches should be removed from the twelfth to the fourteenth day. In favorable cases the patient may sit up by the middle of the third week. Trained nursing, frequent visits, and promptness in meeting emer- gencies count for much in securing favorable results. In conclusion, it may be proper to state that if the patient's con- dition at the outset is fairly good, and the operation is performed with 442 OBSTETRIC SURGERY. every attention to detail, such as a well-equipped hospital renders possible, and the after-management is intelligently conducted, the prognosis is hardly doubtful. Recovery will almost certainly follow, and a new triumph will add to the fame of Sanger. But if the patient has been operated upon in her own home, after a lingering labor, without needed assistance, perhaps by the light of a kerosene lamp and with preparations of a make-shift character, and after the work is ended she is left to the care of ignorant, prejudiced persons, it may be proper to call the operation by the name of Sanger, but recovery, if it occurs, must be regarded as partaking of the nature of a miracle. Porro's Operation, or Ovaro-Hystorectomy. — The characteristic feature of the Porro operation consists in the removal, after the per- formance of the C^esarean section, of both uterus and ovaries. As the result of experiments upon animals, its theoretical practicability was demonstrated as early as 1769 by Cavallini, and later, in 1823, by Blundell. G. Pli. Michaelis, in 1809, after referring to the danger from reaction following injury to any of the abdominal viscera, goes on to say : " That the danger specially depends upon this reaction, we see not only from the often greater associated disorders in other organs, but from the experience that, when the uterus has been re- moved so that the reaction in other organs falls away, the danger appears to be much lessened. Several cases are known where the uterus has been excised by ignorant persons without the occurrence of violent disturbances [Zufalle]. ... It is a question, therefore, whether the Caesarean section would not be rendered less dangerous by connecting with it the extirpation of the uterus." The ablation of the uterus after Cassarean section was not, however, actually executed upon the living human female until 1868. The first operation was performed by Dr. Horatio R. Storer, of Boston, in the case of a patient whose delivery was rendered impossible by the natural passages, owing to a large-sized fibro-cystic tumor blocking up the pelvic cavity. The haemorrhage which followed the incision into the uterine cavity prov- ing frightful. Dr. Storer ligatured the cervix, and, having applied the chain ecraseiir, slowly removed the mass. Both the child and placenta were in a state of decomposition. The patient lived sixty-eight hours. At the time of the occurrence the hardihood of the operator was the subject of a good deal of unfavorable comment. In 1874 Professor Edward Porro, of Pavia, having succeeded in preserving the lives of animals from which he had removed the gravid uterus, decided that, as soon as a chance offered, he would add to the Caesarean section as a completive measure the ablation of the uterus and its appendages. The sought-for opportunity presented itself on the 31st of May, 1876. The patient had a rachitic pelvis, with an antero-posterior diameter reduced to one inch and a half. The child CESAREAN SECTION.— OPERATIONS OF THOMAS AND PORRO. 443 was extracted living, and the mother survived. After the publication of Porro's report, the two Brauns and Spaeth, of Vienna, where the Cassarean section had been jDroverbially fatal (no case saved in this century), resolved to give the new operation a trial. Spaeth led off with a success in June, 1877. In 1888 C. Braun von Fernwald had operated twelve times with eight recoveries. Breisky operated seven times. All his cases recovered. So, too, Leopold has had eight cases, with eight recoveries ; Krassawsky, five cases, with one death ; Frank, six cases, with one death ; Fehling, five cases, with one death ; Tait, seven cases, with one death ; and in the Santa-Caterina Hospital, in Milan, ten women were saved in thir- teen operations. But while in practiced hands, with favorable sur- roundings and skilled assistants, the results have been brilliant, all op- erators have not been so fortunate. Thus, Dr. R. P. Harris, who has with untiring zeal made all questions connected with the Caesarean sec- tion his peculiar province, informs me that the number of operations performed to March, 1885, in which the uterus and its appendages were removed after the extraction of the child, had swollen to 164 (3 mori- bund at time of operation), of which 70 only ended in recovery, or a little over 43 per cent. In a late paper * he states that in the five years ending with the close of 1889 there were reported 158 operations with 47 deaths, or a mortality of 29 per cent. Chason, however, has collected 45 cases, reported between 1887 and 1889, with but six deaths, and in Meyer's f statistics for 1890 32 cases are given, with five deaths ; an indication that the ill-success of the earlier trials was due rather to faulty methods and to defective asepsis than to the impracticable nature of the operation. The inferior rank it now occupies as compared Avith the Cesarean section is not due to its being more dangerous, but to the fact that it involves a serious multiiation. The removal of the uterus and its appendages as a sequence to the Caesarean section is, however, indicated : In osteo-malacia, owing to the influence of ovaro-hysterectomy in arresting that malady ; in uterine atony following the Sanger Cesarean operation ; in cases where septic infection of the endometrium has occurred during labor ; in new formatipns of the uterus, the removal of which is coincidently desired ; in obstruction to the free escape of the lochia due to cicatricial narrowing of the parturient canal, and in complete rupture of the uterus with the passage of the child into the abdominal cavity. Operation. — The preparations and the details of the operation are the same as in Csesarean section, with the exception of those which have reference to the ablation of the uterus and the prevention of * Status of Caesarean Surgery, Gyn. Trans.. 1891, p. 120. f Jahresbericht ueber die Fortschritte auf dem Grebiete der Geburtshtilfe und Gynaek., IV Jahrgang, 1891. 444 OBSTETRIC SURGERY. hsemorrliage. Careful attention to the details of antiseptic surgery is essential to a successful issue. In Porro's first case the abdominal incision was nearly five inches in length. After opening the uterus • and removing the foetus, the placenta, and the membranes, Porro lifted the emptied organ from the abdomen, and placed the serre-nceud of Cintrat around the lower segment, just above the os internum. The tissues were then constricted until all haemorrhage from the cut uterine surface was arrested. The uterus was then cut away with a bistoury, the stump was brought outside of the abdominal wound, and held in position by strapping the handle of the serre-nmud to the pa- tient's right thigh. Miiller modified Porro's original method by en- larging the first incision upward sufficiently to enable an assistant to lift the uterus outside of the abdominal walls, and by applying com- pression above the cervix (either the wire ecraseur or the Esmarch bandage) before opening the womb and removing the child. This plan offers the obvious advantage of rendering the operation bloodless, and of making it easy to prevent the entrance of the amniotic fluid into the abdominal cavity. Breisky, Litzmann, Miiller, Taruier, and Elliott Eichardson, of Philadelphia, found no difficulty in tlius draw- ing the uterus outside the abdominal cavity ; Spaeth, "Wasseige, Tibone, Chiara, and Carl Brauu, on the contrary, either encountered great diffi- culties in performing the manoeuvre, or were obliged to abandon it altogether. According to Harris, there have been forty-two Porro- Miiller operations, with the saving of twenty-one mothers and thirty children. The compressors which have so far been employed are the Cintrat serre-nmud, the chain ecm^e^^rwith a Pean attachment, render- ing it possible after detaching the chain from the handle to maintain the constriction, the various forms of wire ecraseur, and the elastic ligature. Compression should be made slowly, and should not be car- ried to the extent of cutting through tlie peritonteum. Owing to the' liability of wire to break, great care should be taken in its selec- tion. In case of accident, a second instrument should be held in readiness. Fehling, whose excellent record we have already noticed, gives the followmg directions : After careful disinfection of the abdominal sur- face, the incision should be made in the median line. As the ab- dominal coverings are for the most part thin, ligatures are rarely ne- cessary. The peritonaeum should be divided upon a grooved director. Then either a median incision is made through the uterine walls with the uterus in situ and with the precautions against hfemorrhage de- scribed in connection with the older operation, or, as recommended by Miiller, the uterus, after enlarging the abdominal wound, should be tilted laterally, and withdrawn outside the abdomen previous to sec- tion. An elastic .ligature, placed rapidly around the lower uterine segment, furnishes a safeguard against hsemorrhage. In the Porro CESAREAN SECTION.— OPERATIONS OF THOMAS AND PORRO. 445 operation proper the elastic ligature is used after removal of the child ; in the Midler modification, Avhich Fehling prefers, the ligature is ap- plied previous to uterine section. In the latter case the child should be extracted as speedily as possible, for the sudden interruption of the placental circulation is decidedly more dangerous to the child than when it takes place gradually. The diameter of the ligature should be about one third of an inch. After the removal of the child and the tying of the cord, the field of the operation should be cleansed and the after-birth should be removed. Feliling next recommends the apiDlica- tion of a second ligature beneath the first. Then the uterus and ova- ries are to be removed, the stump cauterized, and pins inserted above the ligatures to prevent the recession of the stump. To insure the speedy and complete union of the peritoneal surfaces the latter should be carefully stitched to the stump beneath the ligatures. For this pur- pose a round needle and carbolized silk should be employed. Single sutures passing through the jjeritoneal borders and the uterine tissues should be introduced below and to the sides of the stump, and two sutures through the peritoneal borders and uterine tissues upon the upper surface of the stump. Above the latter two or three more sut- ures should be employed to bring together the peritoneal border alone. The abdominal sutures should next be introduced, and, after a final cleansing of the abdominal cavity, the wound shoivld be closed. For a dressing Fehling employs iodoform, and fills the funnel-shaped space around the remains of the uterus with chloride-of-zinc cotton. Above he places iodoform gauze and cotton fixed in place by means of a wide bandage. The dressing, except in cases of bleeding or fever, may be left undisturbed for six to eight days. The separation of the stump occurs from the twelfth to the fifteenth day. Among recent proposed modifications Sutugin* recommends, as a means of shortening the healing process, that, after the separation of the elastic ligature, the stump should be first scraped and pared to se- cure a raw surface, and that then the borders should be closed by liga- ture. For a day or two he leaves in the lower angle of the wound to secure drainage a tent of iodoform gauze about the size of the little finger. Frank opens the abdomen and the uterus and removes the foetus, then inverts the uterus and applies an elastic ligature which includes ovaries and cervix outside of the vagina. The abdominal wound is next closed and the uterus is amputated below the ligature. In this latter act the tissues are first incised down to the peritonseum, to which a separate ligature of silk is applied. The recommendations for this plan are said to be the simplicity of the technique, the rapidity with which the operation can be completed, and the minimal risk of * SuTUGix, Die Bedeutung des Porrosielien Kaiserschnittes, etc., Centralbl. far Gynaek., 1889, No. CG. 446 OBSTETRIC SURGERY. infection, Frank has operated eiglit times in the manner described, with the loss of but one patient.* The intraperitoneal treatment of the stump, doing away with the dangers arising from necrosis, is correct in principle, but up to the present has not yielded as good results as the extraperitoneal method. It is indicated, however, after the removal of myomata imbedded in the pelvic cavity, and in cases where the Porro operation is employed for uterine rupture, when, owing to the deep seat of the rent, it is im- possible to form a pedicle of sufficient length to reach above the ab- dominal incision. The technique necessarily varies with the conditions. In general terms it may be stated that the plan of operation consists in turning out the uterus and applying a double series of ligatures to each of the broad ligaments. Between the median and outer ligature row the tis- sues are then divided and an elastic ligature is placed about the cervix. After amputation of the uterus a wedge-shaped portion should be ex- cised from the surface of the stump, the cervical canal after thorough disinfection should be cauterized with the thermo-cautery, deep catgut sutures should be introduced to close the internal orifice of the cervix, and deep and superficial sutures inserted to approximate the muscular and serous surfaces together. After the removal of the rubber ligature the sutures should be tightened, and new ones introduced if oozing should render the latter necessary. Bleeding from the uterine artery is best controlled, according to Fritsch, by passing the central sutures obliquely, and in such a way as to cross one another, thereby including the vessel between them. Fritsch and Lohlein exsect the wedge of tissue from above downward instead of in a transverse direction, so as to make the line of the approximated surfaces run parallel to the ab- dominal incision. Instead of dropping the stump they sew its perito- neal surface to the abdominal peritonaeum, while sutures passed through the abdominal walls and the extremities of the line of union on the stump serve to hold the line between the cut surfaces of the abdominal wound and above the peritonaeum. Subsequent oozing into the perito- neal cavity is thus guarded against, while the healing is promoted by suitably applied aseptic dressings. Fritsch, before closing the abdomen, likewise employs a stitch to fasten the severed border of the broad liga- ment on each side to the peritoneal surface of the stump. In fibroids seated below the pelvic brim the cavity left after enucle- ation should be closed by a series of deep and superficial sutures, or where of krge size a counter-opening should be made into the vagina and drainage secured below by means of iodoform gauze, while the peritoneal borders of the capsule are sewed carefully together. In like manner in uterine rupture when a rent extends into the broad liga- ment, the safest plan seems to be to close the stump, after the amputa- * Vide Beaucamp. Arch. f. Gynack., vol. xl, p. 117.

Thomas's Operation, or Laparo-Elytrotomy. — In Professor Thomas's operation, the dangers of opening into the peritonaeum and wounding the uterus are avoided by incising the walls of the abdomen in the line of Poupart's ligament, lifting the peritoneeum, and dissecting down to the vagina, dividing the vagina transversely, and then, having reached the cervix, extracting the child through the passage thus artificially created. The credit of defending the practicability of the extraperitoneal delivery of the child above the pelvic brim belongs chronologically to Ritgen. It was the natural outcome of the teachings of Abernethy and Cooper, to whom we owe the ligation of the external iliac artery without opening the peritonaeum. The modus operandi was carefully thought out by Ritgen, and was put by him to the practical test Octo- ber 1, 1821. The incision through the vagina, Avhich was made with a sharj) bistoury in a longitudinal direction, was, however, followed by such profuse haemorrhage that the operation was discontinued, and the ordinary Caesarean section performed in its place. The patient died at the end of fifty-eight hours.* In 1823 Baudelocque the younger, unaware of the work of his predecessor, advised an incision down to the j^eriton^eum along the external edge of the rectus muscle, extending from the umbilicus to two inches above the pubes, separating the peritonaeum from the iliac fossa with the finger introduced into the lower end of the wound, in- cising the vagina to a length of four and a half inches, and then leav- ing the expulsion of the child to nature, or extracting it with the short forceps. In 1884 he published an essay reporting two cases in which he had tried his plan, modified, however, by substituting the flank incision of Ritgen for that along the rectus muscle. Like Rit- gen, Baudelocque did not complete his first operation, owing to the extent of the vaginal haemorrhage. In his second case he succeeded in delivering the child, which was, however, dead at the time of his undertaking the operation. Having accidentally pricked the external iliac artery, Baudelocque tied the common iliac, in order to arrest the haemorrhage thence resulting. The labor was likewise complicated by convulsions. Death took place on the fourth day. The merit of first performing laparo-elytrotomy belongs, therefore, to Baudelocque. In 1837 Sir Charles Bell, in his Institutes of Surgery, suggested practically the same plan of procedure as that subsequently advocated by Dr. Thomas. * For the particulars of this and the succeeding cases, the writer is indebted to Dr. Henry J. Garrigues's model essay On Gastro-Elytrotoiny, N. Y. IMed. Jour„ October and November, 1878. 448 OBSTETRIC SURGERY, In 1870 Dr. Thomas, who was at the time unaware of the labors of his predecessors, read a memorable paper before the Medical Asso- ciation of Yonkers, giving an account of, first, laparo-elytrotomy per- formed tentatively upon the cadaver of a woman dying in the ninth month of pregnancy ; and, second, upon a living woman at the end of the seventh month of pregnancy, who had been suffering from pneu- monia for a week or ten days, and was at the time of his visit 171 ar- ticulo mortis. The operation was undertaken in the interest of the child, which Wcis extracted alive, and survived about an hour. In 1874 the operation was repeated by Dr. Skene. The patient had been forty-eight hours in labor, and unsuccessful attempts at delivering her by craniotomy had been resorted to. She was suffering at the time of the operation from exhaustion and shock, which gradually became more marked, and she died seven hours after. In 1875 and in 1877 Dr. Skene had the glory of successfully performing the operation under circumstances of great difficulty, with the result in each case of saving the lives of both mother and child. In 1877 Dr. Thomas had the good fortune to obtain a like triumph. In England the operation has been performed by Drs. Himes and Edes, both times in the inter- est of the child, the condition of the mothers being well-nigh hopeless. Both children were saved. In 1880 Dr. "Walter R. Gillette * extracted by laparo-elytrotomy a putrid child, which he was obliged to perforate and extract with the cephalotribe, the forceps and version having been previously tried without success. The mother recovered with scarcely an untoward symptom. Itt 1883 Professor W. H. Taylor, of Cincinnati, operated with a fatal result. Forceps, craniotomy, the cranioclast, and version had been previously tried in vain. When laparo-elytrotomy was decided upon, the patient was much exhausted, with a very rapid, feeble pulse and elevated temperature. The patient died forty-four hours after the operation. In the same year Professor Jewett, of Brooklyn, oper- ated upon a patient who had been a Aveek in labor. The woman was exhausted by long labor, and previous attempts at replacing the arm, by the use of forceps and by attempts at version. The uterus was in a state of tonic contraction, and the soft parts were excessively cedema- tous. The child died before delivery. The mother died seventy hours later of acute septicaemia. In the year 1885 Drs. Skene and Jewett operated each successfully, and since then an additional successful case has been reported by Dr. McKim. The statistical results, therefore, of laparo-elytrotomy are the saving of seven mothers in thirteen operations. But in no one of the fatal cases were tlie conditions such as to render success a possi- bility. * Gillette, A Successful Case of Laparo-Elytrotoiny, Am. Jour, of Obstet., January, 1S80, p. 98, CESAREAN SECTION.— OPERATIONS OP THOxMAS AND PORRO. 449 The vaginal haemorrhage noted in the cases of Ritgen and Baude- locque can apparently be avoided by tearing the vagina transversely, as recommended by Thomas, in place of incising it with a bistoury. In four of the cases vesico-vaginal fistulse were produced, but all healed spontaneously. The following description of the operation is bor- rowed from the excellent essay of Dr. Garrigues, which has already been quoted. It has received the sanction of Drs. Thomas, Skene, and Gillette, with the exception that, in discussion, all have agreed that it is desirable to insert a perforated drainage-tube through the abdomi- nal wound into the vagina, and to keep the parts cleansed with anti- septic injections. Operation. — " The bowels having been emptied by an aperient and a copious enema, and the os having been fully dilated by Barnes's water- bags, if it is not so already, the patient is placed on her back, on a long, narrow table covered with a mattress or quilts, rubber or oil- cloth, and a sheet. The pelvis is well elevated on a hard cushion, the head and shoulders slightly raised by means of pillows, the legs stretched out. If, from some cause, it has been impossible to dilate the os fully by Barnes's dilators, it is now done by the fingers, or if that is impossi- ble too, it is dilated later through the abdominal wound. The patient is anaesthetized. Since disinfection can not be carried out strictly, and since its administration would give some additional trouble, it is scarcely necessary to operate under disinfectant spray. " The operator takes his place at the right side of the patient. Be- sides one who administers the anaesthetic, four assistants are needed — one on either side of the operator, and two in front of him. The first assistant, standing at the left of the patient's chest, kys his flat hands under the umbilicus and draws the uterus upward and toward the left, thereby putting the skin in the right iliac region on the stretch. Counter-extension may be made by the assistant placed at the right of the operator. A slightly curved incision is made through the skin from a point one inch and three quarters (4-5 centimetres) above and outside the spine of the pubes, parallel to and an inch above Pou- part's ligament, to a point an inch above the anterior superior spine of the ilium. This incision may also be made in the opposite direc- tion, from without inward. By a few touches with the edge of the knife the external oblique muscle is laid bare, and spouting branches of the superficial epigastric artery secured by holding-forceps. The abdominal muscles are cut to the same extent, layer by layer, the ex- ternal oblique, the internal oblique, and the transversalis, the first of which is aponeurotic. The transversalis fascia is very carefully hooked up with a fine tenaculum, and the knife carried horizontally, so as to make a small opening in it, avoiding the peritonaeum that lies be- neath it, separated from it by loose areolar tissue, and sometimes fat. A director is introduced through the opening and pushed between the 29 ^5Q OBSTETRIC SURGERY. fascia and the peritonieum toward the inner and the onter angle of the wound, and the fascia is cut. The best instrument for this pur- pose is Key's hernia director, the one which Spencer AVells uses when incising the peritonaeum in ovariotomy. It is firm, a quarter of an inch (six millimetres) broad, slightly curved on the fiat, well rounded at the end, and has on its concave side a groove that stops a quarter of an inch (six millimetres) from the point of the instrument. Next, the operator places the pulp of his fingers on the peritonaeum, separat- ing it from the transversalis and iliac fascia, until he reaches the vagi- na! wall. The second assistant, placed at the left of the operator, holds the peritoneum and intestines, applying a fine, warm napkin under his hands, in order to be sure not to let them slip. The first assistant draws the uterus vigorously upward and toward the left, in order to expose the deeper part of the vaginal wall on the right side. A female silver catheter is introduced into the bladder by the third assistant, placed at the left hip of the patient and held in the known direction of the boundary-line between the bladder and the vagina, below the ureter on the side on which the operation is being per- formed. A blunt woollen instrument, something like the obturator of a cylindrical speculum, only longer, is introduced into the vagina and applied above the linea ileo-pectinea, raising the vaginal wall as much as possible into the abdominal wound. An incision is made parallel to the ileo-pectineal line and the catheter felt in the bladder, as far below the uterus as possible, in order to avoid the ureter and Douglas's pouch, and incise where there are fewest vessels, cutting down on the obturator witli Paquelin's thermo-cautery, the galvano- caustic knife, or simply cautery-irons (table-knives) only heated to red heat. The surrounding parts are protected by the application of wet compresses around the place to be cauterized. The incision made by the cautery is extended forward toward the symphysis and back- ward toward the promontory by placing the pulp of both index-fin- gers perpendicularly on the edges, and api^lying the force in different places in the direction of the os uteri and the ileo-pectineal line, so as to tear the vaginal wall as far forward as is deemed safe in regard to the bladder and the urethra, the locality of which organs is ascertained by feeling the catheter held by the assistant, and as far backward as the wound in the abdomen will allow. Now the catheter is withdrawn, the membranes ruptured if the liquor amnii has not escaped before, the uterus tilted as much as possible to the opposite side, and the os drawn with the forefinger into the iliac fossa. " The operator draws the child through the double Avound either by simple extraction, or after turning, or by applying the forceps, accord- ing to the presentation and other particular circumstances. The pla- centa is expelled by compressing the uterus, and withdrawn through the wound. CESAREAN SECTION.— OPERATIONS OF THOMAS AND PORRO. 451 " If bleeding occurs, the operator tries to check it by applying liga- tures through the abdominal wound, holding-forceps, styptics, or cau- teries, using a large wooden tubular sjjeculum ; or a Sims speculum may, perhaps, give easier access to the bleeding vessel than anything else. If it be impossible to check the haemorrhage, the vaginal wound must be firmly tamponed from below through the rulva and from the abdominal wound with cotten pledgets soaked in cold water and squeezed, and held in siiu by broad straps of adhesive plaster round the abdomen, as after ovariotomy. Except in the last eventuality, the bladder is distended by injecting lukewarm milk in order to ascertain if this organ has been injured. If so, the fistula is immediately sewed with catgut, which need not be removed. The wound is cleaned by injecting a stream of lukewarm carbolized water (two per cent), or a solution of thymol (two per thousand), from the vagina and from the abdominal wound. Next, the edges of the abdominal wound are brought together by interrupted sutures, and the lower part of the abdomen covered with borated or sali(?ylated cotton, and surrounded by broad straps of adhesive plaster fastened to the hips, as in ovari- otomy. A jaledget of cotton soaked in carbolized oil (1 to 10) is applied at the entrance of the vagina." Professor William M. Polk has demonstrated that the operation can be performed as well upon the left side as upon the right.* * Polk, N. Y. Med. Jour., May, 1883. THE PATHOLOGY OF LABOR CHAPTER XXIV.

I]sr physiological labor the expelleiit forces are adequate to over- come the resistance encouuterecl. Labor becomes pathological — 1. When the pains are defective ; 2. When the resistance offered by the soft parts or the bony pelvis exceeds the limits of safety to the mother or the child ; 3. When natural delivery is rendered difficult or impos- sible, owing to malformations or malpresentations of the fa?tus ; 4. In consequence of dangerous complications, sucli as haemorrhage, eclamp- sia, and prolapsed funis. From a clinical j^oint of view the anomalies of the labor-pains are divisible into pains in excess, weak pains, pains attended by an extreme of physical suffering, and pains complicated by strictures. Physiologi- cally, however, these different forms are far from composing distinct conditions, isolated from one another. Thus, rigidity of the os is always intensely painful, and is usually dependent upon feeble action of the expellent forces. There is no standard of strength by which the weak- ness or excess of pains can be measured. The terms are always rela- tive, and are used with reference to the obstacles to be overcome. In primiparse strong pains are requisite to induce softening and dilata- tion of the cervix. In multiparse pains may be intrinsically weak, and yet suffice to bring labor to a prosperous conclusion. Much confusion of mind is often occasioned by the double sense in which the term "labor-pains" is employed. Thus, it is frequently stated that the pains are good, when an examination reveals only a feeble measure of expellent force, the word " pains " representing nothing more than an acute degree of physical suffering. Clinically, pains are to be judged by the effects they produce. In practice it will be found convenient to study the various forms of irregular uterine action in connection ANOMALIES OF THE EXPELLENT FORCES. 453 with the results of their influence upon the duration of labor. These results are — 1. Precipitate labor ; 2. Tardy labor. Precipitate Labors. — It is customary to ascribe precipitate labors to an excess of the pains. The term excess is, however, only relative. There is no reason to believe that the uterus ever acts with such a degree of energy a.s per se to constitute a pathological condition. With a large, roomy pelvis, a soft, dilatable cervix, a distensible vagina and perinffium, labor may be terminated by a few strong pains. Such rapid deliveries are not to be regarded with apprehension. As a rule, they are followed by firm retraction of the uterus, and the continu- ance of good contractions acts as a safeguard against haemorrhage. The puerperal state usually pursues a favorable course. Aside from the inconvenience which sometimes results when, perchance, women are suddenly overtaken by labor-pains in the streets or in public places, an easy, rapid labor is to be regarded as one of the varieties of normal labor. Except the adoption of jirecautions against such untoward accidents, they call for no special treatment. When, however, the parturient act occurs in women who possess an undue reflex irritability, which impels them to an excessive use of the abdominal muscles, it is possible for serious mischief to ensue. Thus, if the patient happens to be seized when in the standing posture, the straining efforts may throw the child suddenly upon the floor ; but even here the consequences are less detrimental than would be natu- rally anticipated. The force of the fall is usually broken by the cord. Lacerations of the latter take place at a distance from the navel, and are not followed by haemorrhage. Post-partum haemorrhage, prolapse, and inversion of the uterus are said to be possible occurrences, though of extreme infrequency. When all the exiaellent forces are called into play at an early period of labor, before the rigidity of the utero-vaginal canal has been overcome, the violent straining has been known to cause subcutaneous emphysema of the head and neck, to interfere Avith the utero-placental circulation, and even to produce fracture of the fetal skull. Excessive straining before the soft parts have been properly prepared for the passage of the child may likewise lead to lacerations of the cervix, vagina, and perinseum. The proper treatment for this condition is to lower the reflex irri- tability by hypodermic injections of morphia ; or, better still, by the production of complete anaesthesia, so as to susjoend the action of the voluntary muscles. Tardy Labors. — For the proper understanding of labors protracted beyond the period of safety by irregular uterine contractions, it is necessary to bear in mind the principal features of normal delivery. These are, contractions of the uterus followed by relaxation and dis- tinct periods of repose ; stretching and thining of the muscular fibers below the contraction ring, with retraction of the uterus above that 454 THE PATHOLOGY OP LABOR. point ; softening and dilatation of the cervix ; the fixation of the uterus in the axis of the pelvis ; and the addition of the abdominal muscles to the expellent forces. The first requisite of every normal labor is that the pains shall be good — i. e., shall possess a markedly expulsive character. We have seen that for the uterus to perform work the contractions should not be continuous, but distinctly rhythmical. For effective work, more- over, the excursions of the uterus during a contraction should possess a certain degree of amplitude, and the interval between the contractions should be sufficient to allow the nervous system to recover from the shock of pain. Irregular Pains in the First Stage of Labor. — In the first stage of labor pains are most frequently defective by reason of their short dura- tion. As a rule, short, cramp-like pains occasion acute suffering. When they recur with little or no interval between them, they are very exhausting to the patient. As the cervix in such cases is tense and rigid, it is to this condition that the delay is usually attributed. If, however, the tissues of the cervix are liealtliy, the presentation is nor- mal, and the pains preserve their expulsive character, rigidity of the cervix is never an obstacle to delivery. The activity of the organic changes which lead to softening and dilatation is closely related to tlie activity of the uterine contractions. The exception to this rule in pri- miparae is only apparent. To be sure, in them the firm, closely knitted tissues of the cervix yield more gradually to the dilating forces than in multipara. Indeed, in multii3ara3 we sometimes find the organic changes in the cervix induced by contractions which liave hardly ex- cited the notice of the woman ; but in primiparae, while good pains, under the reservations mentioned, certainly induce softening of the cervix, weak pains effect no changes in its tissues. The uterine contractions may be abnormal from the commence- ment of labor ; more frequently the loss of their expulsive character is a secondary condition. In many primiparous women labor progresses in an auspicious manner for a time, inspiring hopes of a speedy ter- mination. Then the cervix, which had previously been dilating favor- ably, becomes rigid, the sufferings of the patient during each contrac- tion are enhanced, and further advance is arrested. This transforma- tion is not to be accounted for by a spasm of the circular fibers of the OS, but is the result of secondary changes in tlie action of the uterus itself. The right understanding of the phenomenon in question ren- ders it necessary to recall the physiological fact that the uterus is endowed not only with contractility, but with retractile properties likewise. These are shown in a marked way by the manner in which the uterus closes upon its contents after the escape of the amniotic fluid ; so, too, by the manner in which the uterus follows down the foetus during the period of expulsion. Normally, the gradual closure ANOMALIES OP THE EXPELLENT FORCES. 455 of the uterus upon the ovum leads with a dilated os to the permanent formation of the bag of waters. Thus it will be seen that in normal labor retractility is a wholly beneficent possession of the uterus. When, however, from any cause the cervix dilates slowly, and the pains are strong and close together, as the uterus retracts upon the stationary ovum, the excursions made by the labor-pains shorten, which thus tend to assume the clonic form. The continuance of the same process leads finally to the close investment of the ovum by the uterus, when the only indication of contractility which remains is the increased harden- ing of the uterus at short intervals. These changes in the character of the contractions are marked by corresponding changes in the cervix, the condition of the latter affording an index of that of the entire uterus in much the same way that a furred tongue bespeaks a catarrhal condition of the stomach. These secondary changes in the pains are dependent upon a variety of conditions. The tardy dilatation of the cervix, which stands in a causal relation to them, may result from overdistention of the mem- branes Avith amniotic fluid, or from their firm adhesion to the walls of the uterus around the os internum — conditions which, in either case, interfere with the stretching of the lower segment, and thus lead to waste of uterine force by distributing it uniformly over the entire ovum. Again, where there is lack of parallelism between the axis of the uterus and that of the pelvic brim, the presenting part may, by bearing especially upon the anterior portion of the lower uterine seg- ment and of the cervix, exercise so little jn-essure upon the os that its sphincter long maintains its integrity. Finally, irregular contractions may be consequent upon faulty presentations, and upon any form of pelvic obstruction. A special and dangerous form of irregularity results when the mem- branes rupture prematurely, and the entire amount of amniotic fluid leaks away. This, to be sure, is a rare event, as the presenting part, as a rule, acts as a valve which closes the lower segment of the uterus, and prevents the amniotic fluid from escaping. When, however, ow- ing to the small size, the uneven shape, or the hindered descent of the presenting part, the accident in question takes place, as a combined result of muscular retractility and the pressure of the intestines dur- ing the pains, the uterus gradually conforms to the surface of the fcetus. In this way the much-dreaded " dry labors " are produced. The consequences are far-reaching. The retraction of the muscular fibers about the child's neck in head presentations forms an impedi- ment to natural delivery; the disturbance of the utero-placental cir- culation endangers the life of the child ; the uterine walls applied to the convex surfaces of the child become ana?mic, Avhile the re-entrant portions, subjected to negative pressure, become hyperaemic and oedem- atous, extravasations take place into the tissues, the walls are rendered 456 THE PATHOLOGY OF LABOR. friable, the contractions are associated with intense pain, and peritoneal irritability develops.* The prolonged retraction of the uterus may be followed in the end by the entire cessation of pains, and paralysis may ensue. Uterine retractility is not precisely the same force as that which causes the expulsion^ of a fluid from an overdistended elastic sac, for retractil- ity and contractility are in the uterus rarely disassociated from one another. When the uterus ceases to contract, it forfeits, as a rule, its retractile properties likewise, f It sometimes follows, therefore, that, following prolonged tonic contraction, after the evacuation of the uterus, the walls of the latter collapse like those of a pricked bladder. The Treatment of a Protracted First Stage.— The treatment of a protracted first stage has for its object the mitigation of pain and the restoration of their expulsive quality to the uterine contractions. No plan of action should be decided upon without first carefully investi- gating the cause of delay. The suspensive influence of a full bladder or rectum is always to be borne in mind. In face, breech, and shoul- der presentations, and in contracted pelves, the slow dilatation of the cervix is the rule, and, with such exceptions as will be noted in their appropriate connections, do not call for interference. A faulty posi- tion of the uterus should, if possible, be rectified by suitable abdom- inal support. Adhesions of the membranes to the lower uterine seg- ment should be dissected up by the index-finger. In hydramnion, rupture of the membranes, so as to allow the partial escape of the am- niotic fluid, is sometimes serviceable. If the length of the labor is simply due to the insuflftcient uterine action, the conduct of the accoucheur will, in a measure, depend upon the frequency and severity of the pains and the endurance of the patient. If the pains occur at such intervals and with such mildness that the patient is able to eat, to sleep, and to attend to ordinary household duties, the dilatory progress of labor should cause no appre- hension. In pathological conditions it is the element of pain which is most to be dreaded. Pain long continued is a powerful nerve-de- pressant When combined with starvation and deprivation of sleep, it greatly impairs a woman's capacity to resist the perils of the pucr peral period. While, therefore, the indication for treatment is clear enough, it is not so easy in a given case to decide whether the remedy should be applied first to the relief of pain, or whether efforts should be directed at once to the acceleration of labor, so as most speedily to place the patient beyond the hazards of parturition. As a rule, how- ever, it may be stated that anodynes are appropriate in cases where the * Lahs, Die Theorie der Geburt, pp. 285 et seq. t Breisky, Ueber die Beh.imllwng der puerperalen Blutungen, Volkinann's Samml. klin. Vortr., No. 14. p. 93. ANOMALIES OF THE EXPELLENT FORCES. 45Y cervix is but slightly dilated, while accelerative measures naturally re- ceive the preference in those where the first stage of labor is already far advanced. The pain-stilling agents from which the selection should be made are the warm bath, chloroform, chloral by rectal injection, and mor- phine, either alone or combined with minute doses of atropine. In prac- tice it will usually be found convenient to begin with chloroform, and then to sustain its action by the hypodermic injection of morphine, or the rectal administration of chloral, suspending the chloroform so soon as the tranquillizing effect of the latter is developed. Anodynes often accomplish wonders in one of two ways : when, owing to the prolonga- tion of the labor and its attendant pain, the patient's nervous energies have become exhausted, the arrest of pain enables the woman to sleep, and, with the recuperation of power that comes upon awakening, good pains follow, which bring the labor to a happy termination. In other cases, after the employment of the anodyne the parts apparently relax, and an acceleration of labor follows. In these cases the oxytocic effect is probably due to the quieting action exerted upon the spinal nerves. It has been surmised that the nerves of the uterus derived from the cerebro-spinal system possess inhibitory properties — a theory which, if true, readily explains how severe pain suspends uterine action, and how the quieting of pain would restore to the motor nerves their full energy. In a certain proportion of cases the effects of the anodyne or an- aesthetic are of but short duration. In from ten to thirty minutes the acute suffering returns, and the short truce is unattended with benefit. There is an erroneous opinion that, so long as the membranes are un- ruptured, this condition may be allowed to go on indefinitely. It is, however, of the greatest importance that the length of the period of non-interference should be governed by the strength of the patient. There is nothing that requires more judgment in midwifery practice than to decide when the time has arrived at which delay is fraught with more danger than active interference. For my own part, I be- lieve that many fair lives are needlessly squandered because of excess- ive timidity begotten of imperfect obstetric teachings. If iDain-stilling agents do no good, or if the first stage is already far advanced, the physician should seek, by restoring to the pains their expulsive character, to hasten delivery. Of reputed service in cases of uterine insufficiency are the warm vaginal douche, the dilating bags of Barnes, the introduction of a bougie into the uterus, forceps, and the internal administration of quinine, ergot, viscum album, borax, cannabis Indica, cinnamon, or digitalis. The bougie is applicable only to cases where the membranes are intact, and where the pains are weak without being cramp-like in char- 458 THE PATHOLOGY OF LABOR. acter. It should in all cases be surgically clean, as otherwise it can be- come the carrier of infection to the uterine cavity. The vaginal douche possesses a wider range of utility. It is safe and tolerably effective under favorable conditions. It promotes the organic changes in the cervix, stimulates the uterus to contract, and mechanically distends the vagina. Its action is, however, apt to be slow and somewhat uncertain. In a case of overdistention of the amnion, I once saw its employment followed immediately by complete tonic rigidity of the uterine muscular fibers. Of all the resources at our disposal, however, the water-bags of Dr. Barnes stand easily at the head. Passed within the cervix, and dis- tended so as to place the canal moderately upon the stretch, they not only serve to mechanically dilate the os, but are most efficient as reflex exciters of the labor-pains. If left in situ until expelled into the vagi- na by the bearing-down efforts they awaken, the cervix will be found to have lost its rigidity. If necessary, a larger dilating-bag should then be employed in the same way. An attempt to dilate the cervix rapidly and with violence is neither safe nor profitable. To obtain permanent results it is essential to effect the organic changes in the tissues which render them physiologically dilatable. In cases of tonic rigidity of the uterus, the production of normal pains will sometimes be assisted by rupturing the membranes and raising the head, so as to allow a small portion of the amniotic fluid to escajio, previous to re- sorting to the Barnes water-bags. When, after rupture of the membranes, a segment of the head pre- sents at the OS externum, the rubber bags are of less service. In such cases often we are able to accomplish speedy dilatation by simply ask- ing the woman to hold her breath, and to re-enforce the uterine pains by the action of the auxiliary muscles. If this plan fails, forceps should be applied, and the head be made to serve as the dilating body. To avoid lacerating the cervix, the tractions should be intermittent, and should be suspended during the acme of the pains. The rule given for the preservation of the perinaeum will be found most service- able in attempts to maintain the integrity of the cervix, viz., that the extraction is most safely accomplished during the period of greatest relaxation, and not at the moment of extreme tension. Of the various internal remedies to stimulate uterine action, ergot should, in the first stage of labor, be unqualifiedly proliibited. In spite of numerous favorable experiences from its use, its tendency to intensify tonic contraction of the involuntary muscular fibers makes it always a perilous drug. The enthusiastic praises of quinine by Drs. Fordyce Barker and Albert H. Smith, of Philadelphia, warrant fur- ther trials of its efficacy. Dr. Smith says : " I do not hesitate to give it in every case, because, even where there is no decided inertia at the onset of labor, there may be failure of the powers of the mother from I ANOMALIES OF THE EXPELLENT FORCES. 459 early exhaustion and fatigue, and we get the benefit of the qiiinia in diminishing this tendency and also in promoting the condensation of the uterine fiber after the delivery of the placenta, thus lessening the dangers of post-])artuni haemorrhage and the annoyances of the after- pains so commonly resulting from a slow condensation of the uterine muscle."* He recommends the bisulphate in a fifteen-grain dose, which he declares acts altogether beneficially as a stimulant to the normal uterus. The other agents mentioned as possessing direct or incidental ecbolic properties are now chiefly of historic interest. Irregular Pains in the Second Stage of Labor. — In many cases the pains maintain their normal quality until the completion of the first stage of labor and the descent of the head to the floor of the pelvis. AVlien in the second stage of labor the pains become inefficient and lose their expulsive character, the non-advance of the head is usually attributed to a rigid perinasum. But it is a matter of every-day expe- rience that with really good pains and normal head mechanism the perineum speedily loses its rigidity. Of course, it is not denied that in primiparffi the organic changes which effect the softening of the perinteum need for their accomi^lishment relatively stronger pains than in multipara. The faulty action of the expellent forces in the second stage is due either to exhausted nerve-power or to excessive uterine retraction. In the former case, labor becomes powerless from the feeble character of the juiius; in the latter, it results from the with- drawal upward of the uterine muscle, and the consequent lessening of the intra-uterine pressure. These cases of retraction are worthy of special consideration. Thus, Hofmeierf found in a number of in- stances where the head rested on the pelvic floor that the contraction ring, which was made out by palpation through the abdominal walls, was situated at from five to seven inches above the symphysis pubis, so that the contractile portion of the uterus covered not more than one third of the foetus. Under such circumstances, while the ^jatient suffers from intense pain, the contractions of the partially emptied uterus do not possess the force to overcome the resistance of a rigid perinaeum. Treatment — In all cases of protracted second stage, before decid- ing upon the existence of uterine irregularity, both the bladder and the bowels should be emptied, and care should be taken to exclude the existence of obstruction from the bony pelvis If the only resistance to be overcome is that furnished by the soft parts, weak pains should be re-enforced by the action of the abdominal muscles. After rotation of the head is completed, a new vis a tergo may be supplied by press- ure applied to the breech through tlie abdominal walls after the method * Albert IT.

The force, the frequency, and the length of the acts of expression should of course be decided by the judgment and experience of the operator. ' Where the movements of flexion and rotation have been imper- fectly performed, little is to be expected from any of the forms of expression. The available remedies are then ergot and the forceps. Of these, the advantages of safety and celerity are all on the side of the forceps. Many practitioners, however, who have observed that in practice ergot often acts likewise with speed and safety, accord to it a large measure of confidence. But along with these more fortunate experiences there is a shady aspect to be remembered. When the tardy labor is due to tonic retraction, the use of ergot is calculated to aggravate the sources of delay. In other cases tonic retraction is the direct result of ergotic action, and, as a consequence of restricted utero-placental circulation, the life of the foetus is jeopardized. When, therefore, the drug is used, the heart-sounds of the foetus should be carefully watched, and, with the first signs of failing force, the forceps should be applied to rescue the child from the impending danger of asphyxia. Note on the Use of Ergot in Parturition. — Secale cornutum, or ergot, the active principle of which is ergotin, according to Buchheim,t and ergotic jicid, according to Zweifel,}: is universally acknowledged to increase the fre- quency, length, and power of the uterine contractions during parturition, and to finally induce a tetanic condition of the uterine muscular fibers. Its action upon the unimpregnated uterus is the same in kind, but less marked in degree, and of less constant occurrence. Robert,* on the other hand, denies the ecbolic properties of either of those constituents. He maintains that it is cornutin, which excites the uterine contractions, and that the abortifacient element is sjihacelin acid, to which also the tetanic rigidity produced by ergot is due. The views of high authorities in regard to the manner in which these effects are produced present irreconcilable differences. Wernich || attributed the ecbolic properties of ergot to irritation of the uterine nervous centers, induced by * E.

This anaemia is referred by him to loss of tone in and dilatation of the veins, whereby venous congestion, leading to secondary arterial anaemia, is produced.* Other ob- servers assume a primary contraction of the capillaries, with a consequent in- creased arterial pressure, as the source of the anaemic irritation of the nerve- centers; while still others believe direct stimulation of the uterine muscular fibers by the ergot to be the cause of their exaggerated contractility, t Kohler refers the uterine contractions producea by ergot to increased irrita- bility of the peripheral nerves, in conjunction with anaemia of the spinal cord.J These conflicting views pertain chiefly to points of purely theoretical interest, and need not prevent the obstetrician from obtaining a clear conception of his duty in the practical administration of ergot. The above-mentioned incontro- vertible facts concerning its operation sufiice to guide tlie physician in the em- ployment of this useful drug, even if he be unable at present to definitively decide regarding the exact mechanism of its physiological action. Ergot should never be exhibited during the first stage of labor, because the tetanic uterine contractions, which it substitutes for the normal rhythmical ones, tend to prevent the further dilatation of the os uteri and to deprive the foetus of its blood-supply through the constriction of the uterine vessels. Should the membranes have ruptured before the termination of the first stage, the adminis- tration of ergot would endanger the life of the foetus by causing undue pressure to be exerted upon the umbilical cord. We should also abstain from the use of ergot during the second stage, unless it seem necessary as a pro^^hylactic against post-partum haemorrhage. Even under these circumstances it should never be administered if there be the slightest mechanical obstacle to delivery, or if the fetal head be high up in the pelvic canal. Spiegelberg* insists upon the neces- sity of carefully observing the fetal heart after the use of ergot, in order that instrumental delivery may, in case of threatened asphyxia, be promptly resorted to. Benicke records twenty-seven cases in which ergot was administered during the second stage on account of inertia uteri. Spontaneous delivery occurred in only seven of these cases. || Ergot is not specially adapted to the arrest of haem- orrhage accompanying abortion. In these cases, and in haemorrhage caused by retained shreds of the fetal envelopes, the appropriate treatment consists in the tampon and in subsequent complete evacuation of the uterine cavity. The only imperative exhibition of ergot is presented by the occurrence of post- partum haemorrhage resulting from uterine atony. ^ The unyielding, tetanic uterine contractions which it produces act most beneficently by occluding the orifices of the bleeding vessels. Even under these circumstances it should, how- ever, be withheld until after the expiilsion of the placenta, lest the uniform uterine contractions lead to its prolonged retention or interfere with manual efforts for its extraction. Irregular Pains in tJie Third Stage of Labor. — The tardy expul- sion of the placenta, due to atony of the uterus, is of rare occurrence * Wermch, op. cit., p. 97. f Benicke, Ueb. Anwend. d.

As, in rehixed conditions of the uterus, blood pours from the patulous mouths of the torn utero-placental vessels into the fundus, a free external discharge of blood follows of necessity whenever contractions are ex- cited—a fact to be borne in mind by an unpracticed obstetrician, lest he mistake the simple conversion of an internal into an external hajmorrhage for one produced by the manipulations which have been recommended. The whole subject of atony in the third stage is, how- ever, so closely associated with the occurrence of post-partum haemor- rhage that its specific consideration will be reserved for separate study in connection with the hemorrhages which take place during and subsequent to labor. After the birth of the child, retraction of the uterus is Nature's safeguard against hajmorrhage. As a result of the abuse of ergot, or, in other cases, from an abnormal adherence of the jjlacenta, such an extreme degree of retraction may be reached before the completion of the third stage as to lead to the imprisonment of the placenta within the uterine cavity. In these cases complete retraction in the body of the uterus is prevented by the presence of tlie jDlacental mass. Below the latter, where no obstacle is opposed to the shortening of the mus- cular fibers, a constriction results. The stricture is most pronounced at the contraction ring. The lower uterine segment and the cervix proper are usually in a sub-paralytic condition, and widen from above downward to the vaginal insertion. From the shape thus imparted to the uterus this condition is generally known as an "hour-glass contraction." When met with for the first time, it is apt to prove extremely puzzling. In following the cord upward, its continuation through the stricture is sometimes overlooked. In several cases I have known the pulpy mucous membrane of the lower segment to be mistaken for an adherent placenta, and have been, in consequence, summoned to assist in its removal. Treatment.— By patient waiting, relaxation of the stricture usually takes place spontaneously. The result may be promoted by the hypo- dermic injection of morphine, combined with atropine. It is not, how- ever, altogether safe to leave the patient before the expulsion of the placenta has taken place; for, exceptionally, the muscular fibers of the body of the uterus may relax prior to those of the lower segment, and thus haemorrhage may result. Injections of ice-cold water were recommended in such cases by Seyfert, as tending not only to restrain hajmorrhage, but to promote regular expulsive uterine action. Forci- ble dilatation is rarely necessary, and should be reserved for hemor- rhages of an alarming character. In nearly all cases, however, it is practicable, even in extreme examples, to extract the placenta in a short time without force or violence. The plan I have followed of late years, with uniform success, consists in introducing the index and ANOMALIES OP THE EXPELLENT FORCES. 403 middle fingers, with the whole hand in the vagina, to the point of constriction. Then, by pressing the uterus downward, the fingers are brought in contact with the pracen"tal border, Now, it is only necessary to draw a single cotyledon into the canal to render the further extraction a matter of certainty. Under the pressure of the soft placental mass the stricture relaxes slowly. By combining ex- pression with slight traction, the delivery is surely accomplished. The principal difficulty of the operation lies in the manipulations needful to bring the placenta at the outset to the point of stricture, but this difficulty can be pretty certainly overcome by patience and the deter- mination to succeed. During the period of withdrawal the operator should be content with a very slow progression, proportioned to the yielding of the stricture ; otherwise, the presenting portion of the placenta tears away, when the labor expended is lost. Painful Labors. — In nearly all forms of abnormal uterine contrac- tions the pain of labor reaches a pathological degree of intensity. Especially we have had occasion to call attention to the intolerable suffering in cases of long-continued reciprocal pressure between the uterus and its contents. But acute suffering sometimes attends upon the preliminary stages of labor. During the latter days of pregnancy in primipara?, often for a few hours only preceding the advent of true labor-pains in mul- tipara?, contractions occur which normally scarcely attract the atten- tion of the patient. In rare instances, however, the suffering they occa- sion is extreme. In hysterical women these preliminary pains are often of an agonizing character, rendering it necessary to resort for their relief to such palliatives as the warm bath, opium, and chloroform. But, even where hysteria does not exist as a cause, the pains may be so severe, while the cervix has still its normal length, that the woman believes herself in labor, and, indeed, the contractions are as painful as in actual labor. There are no febrile symptoms indicative of inflammation either of the uterus or of its appendages. The pain is like that in muscular rheumatism. Though the term rheumatism of the uterus is often applied to this condition, its pathology is uncer- tain. It is very probable that practitioners confound together, under the foregoing title, a number of distinct affections, such as hysterical hyperesthesia, intestinal irritability, and the early stages of inflamma- tion. Excluding these morbid conditions, there remains a class of cases practically important from the disappearance of the pain upon the induction of intense diaphoresis. Patients who for days have been treated with hypodermic injections of morphine with only mod- erate results are often relieved as if by magic by placing them in a warm bath, and then covering them with blankets, giving in addition hot drinks and Dover's powder, until they become bathed in abundant perspiration. ^Q^ THE PATHOLOGY OF LABOR. It is often difficult toward the close of preguancy to distinguish between colic-pains due to fecal accumulation or the presence of gases in the stomach and intestines, troubles to which pregnant women are especially disposed, and uterine contractions of a painful character. Indeed, in the former case the uterus becomes involved to some ex- tent, so that the cervix is felt during a cramp to simultaneously harden. Moreover, after labor has actually begun, it may become complicated by colic-pains, which exercise in turn a suspensive influ- ence upon parturition. But the colic-pains are themselves inter- mittent, and are therefore liable to be mistaken for those of labor. Thus, it is possible to become involved in perplexities which time alone can solve. Even when we have made out the diagnosis of " false labor," and give an opiate for the relief of the patient, it may happen that the first result of quieting the pain may be the accelera- tion of labor. AVhen this does not occur, we should guard against the return of the trouble by clearing out the bowels by purgatives or enemata. In normal labors, the pulse becomes more rapid at the beginning of each pain, and continues to increase in frequency until the pain has reached its acme, after which a gradual declination follows. But sometimes labor is attended by marked febrile symptoms. There exist rapidity of the pulse between the pains and a continuous elevation of temperature. Now, if, at the same time, the uterine contractions are the source of extraordinary suffering, there is strong reason for sus- pecting that labor is complicated by inflammatory conditions of the organs concerned in parturition. Thus, a latent pelvi-peritonitis may be converted into the acute form by the several acts which comprise normal labor, or the prolonged tonic contraction of the uterus upon the foetus after the rupture of the membranes, especially in neglected shoulder presentations and in contracted pelves, may give rise to inflam- matory affections in the uterus itself. Again, in other cases, a salpin- gitis, especially if of the purulent variety, may become the starting point of dangerous local or general peritonitis. In either case the co- existence of intense pain with febrile symptoms should awaken serious apprehensions. Especially ought we to be upon our guard against the treacherous lull in the symptoms that, as a rule, takes place when labor is at an end. After a day or two we may expect a chill and the return of the fever. In the early stages of metritic and perimetritic trouble, a ten-grain dose of calomel often exercises a beneficent action in arresting the disease. AVhere labor has so far advanced that the induction of artificial diarrhoea is rendered impracticable, opiates, though of inferior value, soothe the pain, and are our next most valu- able resource.

These peculiarities embarrass all attempts at classification. Still, the study of the subject is greatly simplified by the fact that the dimin- ished space is, in the great proportion of cases, located chiefly at the brim. Aside from these, there remain a variety of irregular forms of rare occurrence, each requiring a separate description and plan of treatment. It is to those cases in which the narrowing is chiefly at the brim that the term " contracted pelves " is generally applied. The other forms are all specially designated by some qualifying adjective defin- ing their character. Contracted pelves proper are divided into — 1. The pelvis aequabiliter justo-minor, in which all the diameters, from the brim to the outlet, are diminished in very nearly equal measure. 2. The flattened pelvis, contracted specially in the conjugate diam- eter. In this form the transverse diameter may be normal, or may be diminished. Thus, we distinguish — a. Simple flattened pelves (transverse diameter normal). J. Flattened, generally contracted pelves (narrowing in the trans- verse as well as the conjugate diameter). ^ " As it is rare to find two pelves possessing the same measure- ments, the question arises as to the degree of antero-posterior short- ening which suffices to distinguish the contracted from the normal pelvis. It is often customary to consider the contracted pelvis simply as furnishing a mechanical obstacle to the passage of the child's head ; but this is to overlook a great variety of very important modifications 30 4:^ THE PATHOLOGY OP LABOR. to which it gives rise during pregnancy and labor. These remoter influences are often observable in cases where labor, if considered from the standpoint of length alone, would be regarded as normal. Michaelis* and Litzmann,t whose investigations furnish the basis of modern opinion regarding the contracted pelvis, place the limit at three and a half inches for the simple flattened pelvis, and at four inches for those likewise diminished in the transverse diameter. Yet even above these limits the action of the narrow pelvis is not rarely manifested in disturbance of the normal mechanism of labor. In Germany, Litzmann, Michaelis, Spiegelberg, J and Schroeder place the average frequency of contracted pelves at fourteen per cent, and in my own field of experience, in the Emergency and Maternity Hospitals of New York city, the ijimates of which are, however, almost entirely of foreign birth, every variety and degree of pelvic deformity finds abundant illustration. In our native American Avomen abnormal pelves are rare. I frequently hear from country physicians who attend lectures at the Belle vue Hospital Medical College that, in long years of practice, they have never met with a single instance. Yet it is impossible to study the cases of vesico-vaginal fistula re- ported by Dr. T. A. Emmet * without arriving at the conclusion that the existence of contracted pelves is frequently overlooked. Certainly the immunity of American women is by no means so absolute as to Justify the neglect in which the study of pelvic deformity has so generally fallen. The Diagnosis of Contracted Pelvis.— The diagnosis of pelvic de- formity is based upon direct examination. Certain facts in the previous history of the patient are often of substantial value in the way of con- firmatory evidence, or by directing attention to the probable existence of deformity. Previous History. — Inquiry should be instituted regarding the oc- currence of rickets in early childhood, and especially in this connection as to the period of the appearance of the teeth. Late dentition is an ordinary sign of imperfect bone formation. A cross baby, bottle-fed or improperly nursed, suffering from repeated attacks of indigestion, from restlessness at night, and profuse perspirations, who cuts the first incisor teeth in the second year, has presumptively had rickets. A history of this nature, even in the absence of the grosser evidences of rickets, such as the square head, the pigeon-breast, the tumefied abdo- men, small stature, spinal curvature, enlarged joints, and incurvation of the long bones of the extremities, is to be regarded with suspicion. Data of the kind mentioned are, however, often difficult to obtain, and * Michaelis, Das enge Becken, Leipsic, 1865. t Litzmann, Die Formen des Beckens, Berlin, 1861. t Spiegelberg, Lehrbuch, 1878, Bd. ii, p. 426. * Emmet, Vesico- Vaginal Fistula, William Wood, 1868. CONTRACTED PELVES. 46Y it should be borne in mind tiiat not every case of mild rachitis is fol- lowed by pelvic narrowing. In'struction may likewise be obtained from the history of previous labors. Though a protracted and difficult labor is by no means un- common in well-formed primipar^e, it should stimulate us, both during parturition and subsequent to delivery, to make a careful investigation as to the capacity of the pelvis. A pendulous abdomen and faulty presentations and positions of the fojtus occur with much greater fre- quency in contracted than in normal pelves. Certain of the rarer deformities proceed from inflammations be- tween the sacro-iliac bones and at the hip-joint, from inequalities in the length of the limbs, and from spinal distortion when these diffi- culties occur in early childhood. Pelvic Measurements. — The examination should be made with the patient upon her back, placed preferably upon a hard table covered by a folded blanket, or a woolen comforter. The head and shoulders should be moderately elevated, the knees should be flexed, and the pelvis brought as near to the edge of the table as possible. Facility, in the recognition of abnormal conditions can only be ac- quired by making it a habit to note the general features of the pelvis in every case of labor which is committed to our charge. By experi- ence we acquire a tolerably distinct idea of the relative thickness of the bones, the inclination of the ilia to the horizon, the height of and the angle formed by the symphysis pubis, the size and character of the pubic arch, the length, breadth, and curvature of the sacrum, the position of the promontory, and the distance between the ischia. More exact information is deriv- able from direct measurements be- tween different prominent points in the pelvis. Various pelvimeters have been devised to facilitate the required measurements. Those for determin- ing the distance between certain ex- ternal points are alone of practical value. For this purpose the circle of Baudelocque is the one I have most constantly employed. It requires to be used with caution on account of the spring of the metallic arms. Schultze's instrument possesses the advantages of greater firmness and portability. The points selected for measurement should be bony prominences, easy of recognition, and not covered by soft parts. They should be such as to allow us Fig. 200. — Baudelocque's pelvimeter. 468 THE PATHOLOGY OF LABOR. to form at least approximative conclusions relative to the diameters of the small pelvis. Experience shows iis that, judged by these rules, three measurements only are possessed of real importance, viz., the distances between the anterior superior spinous processes, the distances between the crests of the ilia, and the external conjugate diameter. Fig. 201.— Schultze's pelvimeter. In measuring the distances between the anterior superior spinous processes, the accoucheur should stand by the side of his patient, and, holding the arms of the pelvimeter between the thumb and fingers, apply the points of the instrument to the spines external to the inser- tion of the sartorious muscles. The points should then be pushed backward a number of times along the outer edge of the crests of the ilia, until, after a few trials, the greatest distance between the crests has been determined. The average distances thus obtained are nearly ten and a quarter inches between the spinous processes, and eleven and a half inches between the crests of the ilia. A pelvis in which these measurements are equal, or in which the relations are inverted (i. e., where the distance between the spinous processes is greater than that between the crests of the ilia), is rachitic in character. In rachitic pelves of the second variety mentioned it is customary to select, in measuring the distance between the crests, points situated two and a half inches posterior to the spinous processes. Any considerable falling below the normal average in these two diameters would warrant the diagnosis of transverse shortening in the inner dimensions of the small pelvis. Deductions as to the degree of shortening should, however, be made with caution, as the relations between the diameters of the large and small pelves depend upon such variable factors as the thickness of the bones and integuments and the height and inclination of the ilia to the horizon. CONTRACTED PELVES. 469 In measuring the external conjugate diameter the patient is turned upon her side ; one extremity of the pelvimeter is then placed upon the fossa just beneath the spinous process of the last lumbar vertebra, while the anterior point is made to rest upon the middle of the upper border of the symphysis pubis. The lengtli of the external conjugate, or, as it is sometimes termed from its author, the diameter of Baude- locque, is normally about eight inches. Baudelocque thought that by deducting three inches from the external conjugate in spare women, and three and a quarter inches in women of a fleshy habit, the conju- gata vera could be determined. Litzmann has, however, strikingly shown the fallacy of Baudelocque's deduction. In thirty cases, where he had an opportunity to compare the measurements of the external conjugate with the length of the internal conjugate as determined sub- sequently by post-mortem examination, he found the mean amount to be deducted was about three and a half inches. However, the amount in individual cases widely varied, owing to differences in the thickness of the bones and integuments, tlie maximum amounting to nearly five inches, while the minimum did not exceed two and three fourths inches. But, while the external conjugate does not enable us to esti- mate to a fraction the length of the antero-posterior diameter of the pelvic brim, it furnishes useful information as to the existence in gen- eral of flattening. Thus, if the diameter of Baudelocque measures less than six and one fourth inches, it may be assumed that the pelvis is flattened. If the pelvis measures less than seven and a half inches, flattening may be assumed in half the cases. Above seven and a half inches, antero-posterior shortening is very exceptional.* For internal measurements, the only practical pelvimeter is the hand of the accoucheur. To be sure, it can only determine with ex- actitude the diagonal conjugate, i. e., the distance from the lower bor- der of the symphysis pubis to the promontory ; but from the diagonal conjugate it is possible to calculate the conjugata vera with a closer degree of accuracy than is obtainable by means of any of the ingenious instruments designed to measure directly the diameters of the brim. To ascertain the diagonal conjugate, the index and middle fingers of the left hand should be introduced, well oiled, into the vagina. By pushing the posterior vaginal wall backward, the points of the fingers are made to reach the sacral vertebrae. Then, following the sacrum upward, the promontory is reached. To do this it is necessary to sink the elbow, and give to the fingers a nearly vertical direction. The resistance of a rigid peringeum and the vaginal wall is best overcome by continued, steady, upward pressure. It is often possible by this method to reach the promontory in even normal pelves. During the examination the patient should be requested to raise up her hips. The * Litzmann, Ueber die Erkenntniss des engen Beckens, Volkmann's SammL klin. Vortr., No, 20, p. 148. 470 THE PATHOLOGY OF LABOR. promontory is recognized partly by its convex surface, and partly by the width of the cartilage which intervenes between it and the ad- joining lumbar vertebra. In practice there are two possible sources of error, viz. : an angle may form between the first and second sacral vertebrae where the union has been incomplete, producing a "false promontory " beneath the true one ; or the upper surface of the first lumbar vertebra may project in such a way as to be mistaken for the promontory in cases where the latter, as sometimes happens, forms with the spinal column a very obtuse angle.* Such deviations are not without practical interest, as the prognosis is rendered less promising when the head, in place of a single .point of contact, has to overcome the resistance offered by the surface of an entire vertebra. The measure of the diagonal conjugate is taken by pressing the middle finger firmly against the most salient portion of the promon- 'b^ Fia. 202.— Normal inclination Fig. 20.3.— Diminution of angle Fig. 204.— Increase of angle of the symphysis pubis. between symphysis and pel- between symphysis and (Spiegelberg.) vie brim. pelvic brim. tory, while the radial edge of the hand or index-finger is raised to the Ugamentum arcuatum. The point of contact with the latter is then carefully marked with the nail of the index-finger of the right hand. It is desirable in withdrawing the fingers that they maintain, as nearly as may be, the position assumed at the time of measurement. Finally, with a small rule, the length from the mark of the nail to the tip of the finger is readily ascertained. In calculating the length of the conjugata vera from the measure thus gained, it is necessary to reconstruct the triangle formed by the two conjugates and the symphysis pubis. The diagonal conjugate is the longest of the three sides. The length of the conjugata vera de- pends on the height and inclination of the symjihysis pubis and thj * LiTZMANN, Ueber die Erkenntniss des engen Beckens, Volkmann's Samml, klin. Vortr., No. 20, pp. 152, 153. CONTRACTED PELVES. 471 degree of elevation of the promontory above the symphysis, as may be readily seen by reference to the diagrams. The height of the symphysis pubis may be determined by the finger through the anterior vaginal wall. When the symphysis does not measure above one inch and a half, the subtraction of two thirds of an inch from the diagonal diameter will, under ordinary circumstances, furnish very nearly the conjugate. When the symjihysis exceeds one inch and a half, three fourths of an inch should be deducted.* The inclination of the symphysis pubis to the plane of the brim and the height of the promontory above the upper border of the pubes can only be estimated. When any unusual deviations in either of these regards are found to exist, some special allowance would need to be made by way of compensation. It is just here that judgment and experience furnish the best safeguards against vital inaccuracies. In thin persons during the non-pregnant state the promontory can sometimes be easily reached through the abdominal walls, and an estimate made of the conjugate by deducting, from the distance thus obtained between the jDromontory and the symphysis, the supposed thickness of the intervening tissues. The transverse diameters of the pelvic brim and cavity can be neither directly measured nor calculated with any degree of certainty from other measurements. There are certain other dimensions which we find useful to deter- mine in the rarer forms of distortion, and which will be mentioned in their proper connections. For the three forms of contracted pelvis which at present engage our attention, four measurements alone are of practical value — viz., the distance between the anterior superior spi- nous processes ; the distance between the crests of the ilia ; the exter- nal conjugate ; and the conjugata diagonalis. The Three Principal Forms of Contracted Pelvis. The Pelvis JEquabiliter Justo-minor, or Symmetrically Contracted Pelvis. — This, the rarest of the three forms, presents to the casual view the appearance of a normal pelvis, except that the diameters from the brim to the outlet are reduced in nearly equal measure.- We dis- tinguish two varieties of this pelvis : 1. In the commoner variety the woman may be of small, medium, or large stature, and her figure thick- set, or, on the contrary, graceful and slender. Nothing in either her size or carriage is indicative of any abnormal condition. The pelvic bones themselves, both in their structure and in their connections with one another, are free from all traces of morbid action. They are sim- ply below the standard size. The pelvis as a whole is of the feminine type. Litzmann has shown, however, that in the justo-minor pelvis * Spiegelberg, o/j. cif., p. 433. 472 THE PATHOLOGY OP LABOR. the relations of the different parts to one another are not, as a rule, absolutely the same as in the normal pelvis. Thus, there is diminished width of the sacrum, due in special degree to the small size of the alae ; the rotation forward of the promontory and the curving of the lower extremity of the sacrum are less pronounced; the concavity of the sacrum in the transverse direction is increased; the posterior sacral surface is nearly on a level with the posterior superior spinous processes in place of sinking forward between the ilia ; the height of the anterior and lateral walls is proportionately lessened ; and, finally, there is often an increase in the angle which the symphysis pubis forms with the conjugate.* These peculiarities point to a premature arrest in the development of the bones, whereby the pelvis retains something of the infantile type. The causes of arrest are in most cases traceable to general dis- turbances of nutrition during early childhood, such as scrofula and chlorosis, to rickets, which in place of leading to deformity exception- ally exerts its influence in the suspension of bone-growth, and in rare cases to the influence of hard labor and the carrying heavy weights before the completed development of the body. A few cases in which no morbid conditions can be elicited from the history of tlie patient may perhaps be referred to some original defect in the primitive ma- terial from which the bones were built up. Cases have been reported in which this anomaly appeared to be hereditary, f 2. In veritable dwarfs the diminutive size of the pelvis may simply correspond to the Lilliputian proportions of the entire skeleton. These so-called dwarf pelves — pelves nance — are of the regular feminine type, but the bones are slight, and united, as in the child, by cartilage. They are extremely rare. In pelves of this variety the highest degree of contraction is observed. J Diagnosis. — In i\ve justo-minor pelvis all the external diameters are diminished.

In ordinary cases, it is fortunately safe to base prac- tice upon the length of the antero-posterior diameter. Flattened Pelvis. — AVe have seen that the characteristic of this form is a shortened conjugate diameter. The transverse diameter re- ^ mains at the same time normal, or may sink below the standard. A special distinction is likewise to be made between the flattened pelves of non-rachitic and rachitic origin : 1. The flattened non-rachitic form is the most frequent variety of contracted pelvis. At a first glance, or previous to measurement, it often produces the impression of a normal, well-formed pelvis. It is occasioned by a sinking of the sacrum downward and inward between the two ilia. As this movement takes place without any forward rota- tion of the promontory, the antero-posterior shortening is not confined to the brim, but extends throughout the entire pelvic cavity. Extreme contraction is uncommon, the length of the conjugate rarely falling below three inches. The flattening is of necessity associated with a compensating increase in the transverse diameter. As, however, the flattened non-rachitic pelvis is usually from the outset of small sizet, the compensation hardly suffices to give to the transverse diameter more than the normal dimensions. Indeed, it is not infrequent to find a slight lessening in the transverse diameter associated with aur tero-posterior contraction. There is nothing definitely settled regarding the etiology of this deformity. It has been attributed to lifting and carrying heavy bur- dens before the age of puberty, to incompletely developed rickets, and to retarded development. During life it is not easy to distinguish between this form and that of the symmetrically contracted pelvis. In both the external signs of rickets are absent, the relations between the spines and crests of thoi ilia normal, and in both all the external diameters may be somewhat diminished. The stature of the individual furnishes no clew; for, though both forms occur rather more frequently in diminutive persons, there are numerous exceptions to the rule. The sinking of the sacrum between the ilia is not easy to recognize. In a well-marked example, however, the relatively greater shortening of the conjugata externa and the diagonal conjugate,* with the difficulty of palpating the inner sur- face of the pelvic lateral walls, furnish the prominent points for guid- ance. Sometimes, when no bony union has formed between the first and second sacral vertebrae, a double promontory may be left. * In reckoning the true conjugate from the diagonal diameter, the same reduc- tion needs to be made as in the normal pelvis, for, though the outward slant of the symphysis is increased, this is compensated for by the diminished height of the symphysis and low position of the promontory. (Litzmann, Volkmann's SammL klin. Vortr., No. 20, p. 160.) I CONTRACTED PELVES. 475 2. The rachitic form of flattened pelvis presents the following char- acteristics : The bones are of small size, but usually of normal texture. Some- times, however, they are thin, and even translucent, while in other instances they may be unusually compact and thickened. The ilia are flattened, and run in a nearly horizontal direction. The anterior su- perior spinous processes flare outward, so that the distance between them dift'ers little from that between the widest points of the crests. The promontory projects inward toward the symjjhysis pubis. The upper portion of the sacrum sinks inward between the ilia, and lies farther in front of the posterior superior spinous processes than in the normal pelvis. The upper portion, too, is directed nearly horizontally backward, while the extremity, usually at the fourth or fifth sacral ver- tebra, is bent sharply for- ward. The anterior sacral surface loses its transverse concavity, and becomes either fiat from side to side, or convex from the bulging forward of the sa- cral vertebra. The antero- posterior shortening of the brim is accompanied by a compensating increase in the transverse diameter. As, however, the rachitic pelvis is originally under- sized, the transverse diameter rarely exceeds normal dimensions. The horizontal rami of the pubes are flattened, and the acetabula are di- rected to the front. The cartilage of the symphysis pubis generally projects inward, the pectineal line is often unusually sharp, and at times terminates at the insertion of the psoas muscle in a projecting spine. Below, the ischia diverge from one another, and the arch of the pubes is widened. The result of these changes is to produce a shallow pelvis, with contraction at the brim and widening at the outlet. The shape of the brim varies between a long ellipse and that of a heart or kidney, the different degrees of variation depending upon the extent of the displacement forward of the promontory. Externally, owing to the horizontal position of the sacrum, a depression exists in the lumbar re- gion, the sulcus between the nates is broad and superficial, and the anal orifice is exposed to view. To apf)reciate the rachitic pelvis, it is necessary to bear in mind the changes wrought by rickets in the bony structures. In the physiolog- ical growth of the pelvic bones, new cell-elements develop beneath the Fig. 306.— Flattened rachitic pelvis. (Wood's Museum.) ^^Q THE PATHOLOGY OF LABOR. periosteum and adjacent to the cartilaginous borders upon the articular surfaces. These cell-elements promptly ossify, and thus provision is made for the increase of the bones in extent and thickness. Simulta- neously with the formation of the new bone, medullary spaces are pro- duced in the bony tissues by a process of absorption. Now, in rickets, while the new cell-elements are deposited in such numbers that the preparatory layer is often five to ten times the normal thickness, the process of ossification is suspended or im])erfectly performed. Thus, the rachitic pelvis consists of a number of more or less firm, bony masses, covered with soft osteoid layers, with broad cartilaginous bor- ders at the articular surfaces. These changes combine to increase the pliability of the pelvis, and to retard its growth. The pelvic deformity resulting from rickets is mainly due to the weight of the superimposed body. The pressure from above which the trunk exerts pushes the promontory forward toward the median line. At the same time the upper portion of the sacrum rotates upon its transverse axis, so that its posterior aspect is nearly on a line with the horizon. The bodies of the vertebrae sink downward between the flex- ile wings, whereby the concavity of the sacrum from side to side is effaced. The pliant border of the iliac articulation yields somewhat, and, as it is drawn inward by the sinking of the sacrum, the traction of the strong sacro-iliac ligaments ajoproximates the posterior superior spinous processes to one another. The traction of the sacro-tuberous and sacro-spinous ligaments aids in hooking forward the lower extrem- ity of the sacrum, though to this deformity the pressure exercised upon the end of the spinal column by the half-sitting, half -recumbent posture affected by rachitic children unquestionably contributes its part. If we regard the sacrum as a fulcrum, and each os innominatum as a lever, it is evident that the traction of the sacro-iliac ligaments, under the pressure upon the sacrum from the trunk, would produce a separa- tion of the innominate bones in front were it not for their firm union at the symphysis pubis. The result of these two counteracting forces is an increased incurvation of the bones at the point of weakest resist- ance, which is situated near the articular surfaces. In advanced rick- ets, where the bones are plastic and willowy, the linea arcuata is often bent at an angle, so that the greatest transverse diameter divides the pelvic brim into a posterior and anterior half. To the latter belong the acetabula, to the former the two ilia. The outward direction of the anterior superior spinous processes is probably due in a measure to an arrest of development, as the S-shaped curve of the crests of the ilia does not normally develop until after the age at which rickets usually makes its appearance (Kehrer). The flat- tening of the ilia is partly due to the drag of the sacro-iliac ligaments, and partly to the action of the sartorii and gluteal muscles. The di- vergence of the ischia and the wide arch of the pubes are the product CONTRACTED PELVES. 477 of the increased transverse diameter, and the attachments of the ro- tator and adductor muscles of the thigh.* The diagnosis of the rachitic form of flattened pelvis is easy, if the characteristic changes are kept in mind. The prominent features to which the attention needs to be directed are ; the relations of the dis- tances between the crista ilii and the anterior superior spinous pro- cesses (diminished difference, or distance, between the anterior superior spinous processes may equal, or even exceed, that between the crests) ; diminished distance between the posterior superior spinous processes ; diminution of the external conjugate ; the form and direction of the sacrum ; the shape of the arcus pubis ; and the marked projection of the promontory. A false promontory at the second sacral vertebra is not uncommon. The deduction to be made from the conjugata diago- nalis in estimating the conjugata vera averages the same as in the nor- mal pelvis. However, it is in rachitic pelves that the widest variations in this respect occur, making it specially necessary in each case to ob- serve the height of the promontory and the length and direction of the * symphysis pubis. Flattened Generally Contracted Pelves. — In this variety we distin- 1^ guish likewise a rachitic and non-rachitic form, the latter occurring rarely, the former with comparative frequency. The non-rachitic form is apj^arently the joint product of a small justo-minor pelvis and the forces which lead to a sinking of the sacrum between the ilia. In these pelves a short symphysis and a low prom- ontory contribute often to reduce greatly the difference between the diagonal and the true conjugate. During life it is difficult to distin- guish it from the justo-minor pelvis. The rachitic form is found usually in persons of small stature. It presents in a striking degree the marked peculiarities of the rachitic pelvis. The existence of transverse narrowing is recognized by the narrowness of the hips, by the ease with which, in internal examina- tion, the side walls can be felt with the palmar surface of the half- hand, and by the modifications it produces in the mechanism of labor. * While Litzraann (Die Pormen des Beckens) and Schroeder (Lehrbuch der Ge- burtshulfe) lay special stress upon the weight of the body as the main factoi" in pro- ducing the deformities of rickets, Kehrer (Zur Entwickelungs-Geschichte des rachit. Beckens, Arch. f. Gynaek., Bd. v, 1873, p. 55) has shown that many of the changes characteristic of rickets occur in congenital cases — i. e., before the action of the weight of the trunk is brought into play. Kehrer refers the changes, therefore, in the main, to muscular action. Fehling (Die Entstehung des rachit. Beckens, Arch, f. Gynaek., Bd. xi, p. 173) ascribes the deformities in rickets to disturbances of growth and persistence of the fetal type. Engel (Wiener med. Wochensehrift, 1873, No. 40) sought to prove the deformities to be the result of partially arrested growth. J. Veit (Die Entstehung der Form des Beckens, Ztschr. fiir Geburtsh. and Gynaek., vol. IX, p. 347) furnishes strong evidence in favor of Litzraann's theory. 478 THE PATHOLOGY OF LABOR. (y Fig. 207.— Small symmetrical rachitic pelvis. (Wood's Museum.) Irregular Racliitic Pelves. — For convenience' sake it seems desirable to attach to the description of the flattened form the influence of two additional forces, which, upon occasion, operate to still further modify the shape of the rachitic pelvis. These are lateral pressure of the heads of the thigh-bones at the acetabula and the various forms cff spi- nal curvature which so commonly result from rickets. Pressure at the acetabula is rarely an operative force, because rick- ets usually is developed at the time of the first dentition — i. e., before the child has learned to walk — and it is not until after the disease has de- clined that the child attempts to use its lower extremities. In the excep- tional cases in which the disease oc- curs later, after the child has begun to walk, the lateral pressure may act in either one of two ways : 1. As a counteracting force to that exercised by the weight of the trunk, in which case the pelvis, provided the pathological processes have only ad- vanced to a limited extent, retains a symmetrical appearance, and resembles closely the justo-minor pelvis. The rachitic origin is betrayed by the shape of the ilia and the signs of rickets in other parts of the body. At the outlet the antero-pos- terior diameter is increased, and the transverse diameter somewhat diminished.* 2. In cases of excessive softening of the bones, either from the se- verity or the long duration of the disease, the acetabula are sometimes pushed inward, upward, and backward, and the symphysis pushed forward, so that the rami of the pubes meet at an acute angle, or run nearly parallel to one another. This lateral compression, in con- junction with the rachitic projection of the promontory, gives to the pelvic brim a tri- angular or clover-leaf shape, closely resembling the distortion produced in osteomalacia. The term pseudo-osteomalacia given by Michalis f to this form is warranted by the existence of certain features peculiar to rickets, such as the small size of the iha, the distance between the anterior superior spinous * ScHROEDER, Schwangerschaft, Geburt. und Woehenbett, p. 77. t MicHAELis, Das enge Becken, p. 139. Fig. 208.— Pseudo-osteomalacia. (Naegele.) ^ CONTRACTED PELVES. 479 processes, and the nature of the changes in other parts of the bony skeleton.* In curvatures of the spine the shape of the pelvis is affected, when a compensatory scoliosis or kyphosis includes the sacral extremity : 1. In scoliosis (lateral curvature) all the rachitic features are usu- ally strongly pronounced. The promontory is tilted to the side of the incurvation, and is pressed by the weight of the body toward the corresponding acetabulum. The ilium, owing to the in- creased pressure at the acetabu- lum from the femur of the affected side, is pushed up- ward, backward, and inward. In extreme cases the approxi- mation of the promontory to the acetabulum may be such as to prevent the entrance of the child's head. The contracted portion becomes, therefore, un- available for obstetrical pur- poses, f 2. In kyphosis (posterior curvature) many of the charac- teristic features of the rachitic pelvis are reversed. As the upper portion of the sacrum is tilted backward, either the conjugata vera is increased or the i^revious rachitic antero-posterior narrowing is greatly diminished. In the movement of the sacrum upon its transverse axis the lower extremity is thrown forward, and the conjugate of the outlet is thereby reduced. Kyphosis, occurring at the beginning of rickets, diminishes the distance between the tuberosities of the ischia, but has little effect upon the inferior transverse diameter after the rachitic changes have once been accomj)lished.

The influence of the contracted pelvis is not confined simply to the embarrassment which the form and size of the pelvis afford to the passage of the child in parturition ; it extends to the production of a multitude of remoter effects, which are often regarded by the unin- FiG. 209.— Scoliosis.

These effects, which include faulty positions and presentations of the foetus, unfavorable shape or position of the uterus, abnormal character of the pains, and the like, enter in turn, except where the mechanical difficulties are absolutely insur- mountable, as inportant elements in the determination of the prog- nosis. For our knowledge of this subject we are indebted almost wholly to the enlightened labors of the Kiel professors Michaelis* and Litzmann.f Influence of the Contracted Pelvis upon the Uterus during Preg- nancy.— In the early months the only way in which the contracted pelvis exerts an influence is in sometimes favoring the dislocation of the uterus backward. This action is liable to take place when, in the second or third mouth, the uterus has been unusually depressed in the pelvis, and the fundus has swung backward toward the sacrum as the uterine axis approximates to that of the pelvic outlet. Under such circumstances the jutting of the rachitic promontory is calculated to mechanically interfere later with the ascent of the organ iuto the abdominal cavity^ in which case the pressure of the inflated intes- tines upon the anterior aspect of the uterus pushes the fundus over the inclined surface of the sacrum, and retroversion is produced. As the gravid uterus enlarges, owing to' the limited space within the pel- vis the version gradual passes into a flexion, which, unless relieved, is followed by symptoms of incarceration. In the latter months of gestation the uterus, as a rule, is lifted to a greater extent above the pelvis than occurs under normal conditions. This elevation is due to the growth of the child, which is prevented from sinking into the pelvis by the contracted conjugate. Sometimes the upward tendency of the uterus is overcome apparently by the resistance of the round ligaments, so that, while the head is retained at the brim, the lower segment hangs empty in the pelvis. At the same time the uterus possesses an unusual degree of mobility, in part due to the lack of fixation afforded by the descent of the foetus into the pelvis, and in part to the laxity of the abdominal walls and the round ligaments. These latter conditions belong, of course, rather to multipara than to women for the first time pregnant. In close connection with these two events, viz., the elevation of the uterus and its mobility, it is not uncommon to observe the higher degrees of the so-called pendulous abdomen, caused by the anteflexion of the gravid uterus. To this deformity, furthermore, the small stat- ure of rachitic patients, the increased inclination of the pelvis, the anterior projection of the lumbar portion of the spine, and the stretched state of the abdominal walls, associated often with separation of the recti muscles at the linea alba, all contribute their part. * Michaelis, Das enge Becken, Leipsic. t LiTZMANN, Volkraann's Samnil. klin. Vortr.," No. 23o CONTRACTED PELVES. 481 Influence of the Contracted Pelvis upon the Presentation of the Foetus. — Faulty presentations occur in contracted pelves more than three times as frequently as in those of normal dimensions.* Thus, when, during the latter part of pregnancy, the narrow conjugate me- chanically prevents the head from sinking into the pelvic cavity, the head frequently glides sidewise or forward, to rest upon an iliac fossa, or upon the upper border of the symphysis pubis. In pendulous abdo- men the uterus, in place of being inclined, when the jjatient is in an upright position, at an angle of thirty-five degrees, becomes nearly horizontal, or may fall forward so that the fundus occupies a deeper position than the inferior segment of the uterus. The great mobility of the uterus admits likewise of extensive lateral movements. These combined causes account for the lack of stability in the foetus and the comparative frequency with which shoulder and breech presenta- tions occur. When the head is fixed at the brim, the conversion of tlie vertex into a brow or face presentation is often simply an exagger- ation of the normal mechanism of labor in a flattened pelvis. If the head, in place of filling the lower segment of the uterus, is retained at the brim, the space left between the head and the uterine walls favors prolapse of the cord and extremities. In like manner, in breech preS' entations, when the breech is detained by the narrow conjugate, the feet are apt to descend first into the vagina. Owing to the progressive relaxation of the abdominal and uterine walls with successive pregnancies, the frequency of these irregularities increases nearly in proportion to the number of previous births. Influence of the Contracted Pelvis upon the Labor-Pains.— When the degree of pelvic contraction permits the delivery of the foetus by the normal passages without resort to embryotomy, the favorable or iinfavorable ending of the labor is in large measure dej^endent upon the character of the pains. Good pains are of vastly more consequence in narrow than in wide pelves. Violent pains, where the mechanical obstacles are insurmountable, either from the smallness of the pelvis, the faulty presentation of the foetus, the position of the child's head, or its size and hardness, endan- ger the integrity of the uterus. Indeed, unless the mechanical diffi- culties are diminished by rectification of faulty positions and presen- tations, or by embryotomy, or unless relief is afforded by the removal of the child by Cesarean section, there is reason to dread in such cases the occurrence of ruptured uterus, or, after retraction of the cervix, that the uterus may be torn from the vagina. Still more frequently weak pains are the cause of unfavorable ter- minations. Weak pains lead to lingering labors. Even in moderate '* Spiegelberg found that, of 544 labors in narrow pelves, the head presentation occurred in eighty-three per cent, whereas the proportion is ninety-five per cent in normal pelves. (Lehrbuch der Geburtshiilfe, p. 448.) 31 482 THE PATHOLOGY OP LABOR. degrees of coutractiou they fail to rectify unfavorable positions of the head or to force the head by the brim into the pelvis. Under such circumstances neither the forceps nor version can be employed without serious risk, while, if a waiting policy is pursued, the amniotic fluid gradually escapes, and, as the uterus retracts down closely upon its contents, the foetus perishes from the gradually increasing hindrances to the uterine and placental circulation. In prolonged labors good pains alternate at intervals with those of less force. There is no standard by which the quality of pains ])er se can be determined. The quality of the pains is to be estimated rather by the results which they accomplish. It may be stated as a general rule, to which, however, there are numerous exceptions, that the strength of the pains is proportioned to the strength of the resistance to be over- come. Strong pains are on the Avhole rather more common in flattened pelves, and weak ones in pelves contracted in all their diameters, with- out, however, the rule possessing any such constancy as to lead one to regard the form of the pelvis as alone possessing any decisive impor- tance in the production of the result.* In the first instance, the character of labor-pains depends upon the innervation of the uterus and upon the thickness and integrity of its muscular structures. The resistance which the narrow pelvis offers to the expulsion of the child increases necessarily during the pains the tension and irritation of the uterine walls ; and these, corresponding to the degree of irritability and contractility of the organ, may i3rovoke pains of unusual violence, which, in turn, terminate, when the resist- ance is not seasonably overcome, in exhaustion ; or the uterine activity may cease without any previous stage of increment ; or, finally, the ten- sion and injurious pressure of the uterus may lead to local circulatory disturbances, and to textural changes which in themselves weaken the strength of the contractions. Michaelis observed that the dangers to the mother and child grow, as a general rule — to which, however, there are numerous exceptions — in proportion to the number of confinements. The increased mortal- ity, especially of the children, he attributed to a peculiar relaxation of the uterus and its pelvic attachments, due to overexertion in previous confinements, f But it must be borne in mind that there are other results of contracted pelves which directly contribute to the fatality of multiparous labors. Thus, we have seen that pendulous abdomen and mobility of the uterus favor abnormal positions and presentations of * Michaelis thought that the partial pressure of the promontory and symphysis excited increased reflex action of the uterus in flattened pelves, whereas the com- plete pressure of the head upon the brim in generally contracted pelves exercised a paralyzing influence {Joe. cit., p. 185). This theory has been called in question by both Spiegelberg {he. cit., p. 452) and Litzmann. (Volkmann's Samml. klin. Vortr., No. 23, p. 177.) t Michaelis, loc. cit., p. 152. CONTRACTED PELVES. 483 the foetus, complications of the utmost prognostic importance ; and, again, that the displacements of the gravid uterus occur with special frequency when the abdominal parietes have lost their supporting power from the overdistention of previous pregnancies. Moreover, when the uterus is not fixed during labor, the expulsive action of the abdominal walls can not be called into play, and thus one of the most important auxiliary forces is lost. Further sources of danger lie in the increased size and hardness of the fetal head observed in later pregnancies, and in the residue of inflammatory troubles which so often proceed from the first difficult delivery.* Influence of the Contracted Pelvis upon the First Stage of Labor.— At the beginning of labor the head in contracted pelves is usually re- tained above the os internum, while the lower segment of the uterus hangs empty in the pelvic cavity. As, under these circumstances, space is left between the head and the uterine walls, the entire column of amniotic fluid acts directly during the pains upon the cervix uteri. The dilatation of the cervix takes place gradually, from above down- ward, as expansion follows upon the descent of the amniotic sac. The shape of the bag of waters depends upon the greater or less degree of resistance offered by the cervical walls. If the latter are soft and dis- tensible, the usual semi-globular contour is maintained. If the cervix offers any material resistance, the membranes, if sufficiently elastic, protrude through the external os in cylindrical form. If, finally, the chief opposing force to dilatation is situated at the os internum, a con- striction may take place at that point, while below the membranes assume a spheroid shape. As the result of these conditions an unim- peded, wave-like movement of the amniotic fluid breaks against the protruding membranes during the pains, the shock of which is apt to produce premature rupture, an event which is all the more inoppor- tune, because in early rupture the circumstances all favor the complete discharge of the amniotic fluid. After the rupture of the membranes, as the head does not descend at once into the cervical portion, the os and cervix reclose, though they continue dilatable in proportion to the degree of distention pre- viously accomplished. Then, as under the influence of the pains the head passes into the pelvis, it gradually once more unfolds the cer- vical canal, and completes its dilatation. Should, however, the head meet with any considerable resistance, so that the pressure of the pelvic brim gives rise to the formation of a scalp-tumor, the latter serves to dilate the cervical canal and the os externum. If the obstacle U such as to prevent the complete descent of the head, two results are l)ossible : 1. If the pains continue strong and no measures are adopted to remove the disproportion, the uterus is either retracted up over the * Spiegelberg, Lehrbuch der Geburtshiilfe, p. 453. 484 THE PATHOLOGY OF LABOR. head of the child as it remains above the brim, until the overdistended vagina gives way, in which case the laceration occurs in a transverse or oblique direction, and usually upon the posterior wall ; or the lower segment of the uterus becomes compressed between the child's head and the walls of the pelvis, and a thinning and bruising of the im- prisoned portion take place. As the uterus contracts, its muscular fibers drag upon the compressed and weakened tissues at the fixed points, which yield finally to the tractile force, and rapture ensues. 2. If the pains are weak or fail outright, the lower segment of the uterus remains undilated until either strong pains are excited or the mechanical hindrance is so far removed by perforation of the head that the weakened pains suffice to overcome the obstacle. Influence of the Contracted Pelvis upon the Mechanism of Labor.— When the pelvic contraction is not such as to render the entrance of the head impossible, the mechanism of labor depends not only upon the size and shape of the pelvic space, but upon the size, form, com- pressibility, and position of the child's head. If a small, soft head has to pass through a pelvis contracted to only a moderate degree, the mechanism may not differ from that of a normal labor. In cases of relatively great disproportion, delivery is only practicable where the position of the head is favorable — i. e., corresponds in each case to the peculiar shape of the pelvis. If the conditions are favorable, and the pains are of normal strength, a segment of the head, after the period of dilatation has been completed, is pressed into the pelvis. The size of the segment depends upon the extent of the resistance offered, and thus, at an early stage, it :^urnishes us a notion as to the degree of dis- proportion existing. As labor progresses, the cranial bones change in shape and overlap one another, so that the head gradually becomes molded to the contour of the pelvic ring. When the largest circum- ference of the child's head has become fixed at the pelvic strait, as the contraction exists for the most part at the brim, the difficulties are usually overcome ; and, where the pains continue good, the remainder of the labor is accomplished in accordance with the ordinary mechan- ism. If the pains fail, or the contraction continues throughout the entire pelvic canal, artificial aid may be needed even after the brim has been passed. In the simple flattened pelvis the occipito-frontal diameter of the head engages in the transverse diameter of the brim. Even when the position is originally oblique, the intermittent contractions of the uterus communicate movements to the smooth surface of the head, which gradually bring its long diameter into correspondence with the long diameter of the flattened pelvis. The head enters the brim with Its posterior surface tilted toward the shoulder, the anterior parietal bone presenting, and the sagittal suture running parallel with, and in more or less close proximity to, the promontory. This lateral obliqui- CONTRACTED PELVES. 485 ty, or obliquity of Naegele as it is termed, is due simj^ly to the fact that the narrowing of the antero-posterior diameter prevents both parietal bones from entering the pelvis upon the same plane. When the broad region between the parietal bosses meets with the resistance of the conjugate, the occipital portion of the head glides to one side, and the narrow bitemporal diameter engages in the contracted space. In this position the occiput usually rests upon the linea terminalis. Owing to the resistance ofEered to the occiput, the forehead sinks into the pelvis, so that the large fontanelle occupies a deeper position than the posterior one. Before the head adapts itself, therefore, to the pelvic entrance, the anterior parietal surface rests upon the symphysis, while the posterior surface is impinged upon by the promontory near the large fontanelle. The latter is felt low down, near the median line. The small fonta- nelle, owing to the dip of the forehead, is occasionally out of reach. Upon the side of the pelvis to which the forehead is turned, the space is incompletely filled out. Tlie adaptation of the head to the pelvic brim is the result of two combined movements, which occur nearly simultaneously : 1. The symphysis pubis furnishes a pivot around which the head rotates in the direction of the fronto-occipital diameter. As the head is pressed into the pelvis from above, the posterior parietal bone is flattened by the projecting promontory. During the descent the dis- tance between the sagittal suture and the promontory gradually widens, and the former approaches the median line. 2. We have seen that the head entered the pelvis at first with a deep position of the anterior fontanelle. By the time, however, the bitem- poral diameter becomes fairly fixed in the conjugate, the anterior fon- tanelle moves upward and forward toward the side wall of the pelvis, while the small fontanelle sinks downward, and occupies a position near the center of the cavity. This movement is not simply a crowd- ing of the entire head in the direction of the brow, but is due to a rotation of the head upon an axis furnished by the conjugate diam- eter,* the symphysis and the promontory furnishing the pivotal points. By the time, in the rotation of the head upon its fronto-occipital diameter, the posterior boss reaches the level of the promontory, the largest circumference of the child's head has already engaged in the straitened brim, and the influence of the pelvic flattening upon the mechanism of labor ceases. Then, if the pains continue good, the flexed head reaches the floor of the pelvis, the occiput rotates to the front, and delivery is accomplished as under normal conditions. In the justo-minor pelvis, the mechanism of labor is nearly the reverse of that described in the flattened form. Thus, as a rule, both parietal bones engage in the pelvic brim at the same time — i. e., * LiTZMANN, Volkmann's Samml. klin. Vortr., No. 74, p. 557. 436 THE PATHOLOGY OF LABOR. the obliquity of Naegele is either slightly marked or absent altogether. Again, the head may enter the pelvis in any of its diameters. To be sure, the oblique diameter is the one it usually occupies. Still, Litz- mann reports two cases in which the sagittal suture corresponded to the conjugate diameter from the outset of the labor.* In the early stao-es, it is not uncommon for the head to oscillate at the brim for a time before fixation takes place. Characteristic of transverse narrowing is the flexed condition of the head from the moment it begins its descent into the pelvis. In- deed, the flexion at the brim equals in degree that which usually ob- tains only at the pelvic outlet. The small fontanelle occupies the middle point of the pelvic space, the neck rests upon the linea termi- nalis, the anterior portion of the head and brow are pressed against the opposite pelvic walls, the long diameter of the head (from chin to vertex) lies in the axis of the pelvis, and the face looks upward toward the fundus uteri. If the transverse narrowing continues toward the outlet, the extreme flexion is maintained after the brow has passed below the level of the promontory. In such cases it may even happen that the small fontanelle may make its appearance at the frenulum in place of turning under the arch of the pubes. Sometimes the head gets fairly impacted in the pelvis, and further advance is rendered im- possible. When the pelvis widens below the brim, the small fontanelle noticeably leaves little by little its central position. In the generally contracted, flattened pelvis, the mechanism of labor is influenced by both the antero-posterior and transverse short- ening. As in flattened pelves, the head usually occupies the transverse diameter, and the sagittal suture looks backward toward the promon- tory. Before the head becomes fixed, it often balances at the conju- gate, rocking to and fro, as the uterus falls from the one side to the other. For a time, therefore, the position of the fontanelles varies with that of the woman. If, however, the disproportion is not abso- lute, and the pains suffice finally to fix the head, the latter usually becomes strongly flexed, and the occiput descends first into the pelvis. When the head does not enter the contracted pelvis in an advan- tageous position, and the fault is not rectified either by the hand or the action of the labor-pains, delivery of the child without perforation often becomes impossible. The most dangerous of these faulty posi- tions are : 1. Cases in which the lateral obliquity of Naegele is exaggerated, so that the presenting part is formed by the anterior parietal bone. The more striking forms usually occur in pelves with an extremely narrow conjugate and a high promontory. The former maintains the head high above the brim, while the latter imparts to the uterus a posterior concavity. As the uterine curve is followed by the axis of * LiTZMANN, Volkmann's Samml. klin. Vortr., No. 74, p. 545. CONTRACTED PELVES. 4S7 the foetus, the head is strongly bent toward the jDosterior shoulder. Sometimes iu presentations of the anterior parietal bone the sagittal suture lies above the j^romontory, and an ear can be left just behind the sympyhsis. 2. Cases in which the pelvic brim is covered by the posterior pari- etal bone. The sagittal suture is then directed to the front, some- times lying even above the sujierior border of the anterior pelvic wall. Near the promontory the squamous suture, and at times the ear, can be felt. This peculiarity is rare in other forms of contracted pelves, but occurs as often as once in five times (Litzmann) in flattened pelves with coincident shortening of the transverse diameter, 3. In cases of well-marked kidney-shaped pelves, the head mav engage in one side of the pelvis only. The occiput then enters usually the side of the brim to which the back of the child is turned. 4. Brow and face presentations are simply exaggerations of the anterior dip of the head, which we have seen is the normal mode of descent during the early stage of labor in flattened pelves. Although not peculiar to contracted pelves, they should always, when present, lead to careful measurements of the pelvic diameters. They increase the difficulties of delivery, not only because of the unfavorable rela- tions of the diameters of the head to those of the pelvis, but because the pelvic deformity interferes with the proper rotation of the chin and forehead forward under the arch of the pubes. In breech presentations, the delivery of the trunk takes place in accordance with the ordinary mechanism in the normal pelvis. The arms, however, are more liable to be reflected to the sides of the head. In flattened pelves the after-coming head enters the brim in the transverse diameter. The position of the chin, where the transverse space is ample, varies with the degree of conjugate shortening. Where the latter is only of moderate extent, the ordinary flexion of the head may not be interfered with. If, however, the disproportion between the head and pelvic diameters is considerable, partial extension takes place. In cases of extreme contraction the entire head may be retained at the brim. The chin is then usually turned forward so as to rest upon one of the pubic rami, while chin and occiput occupy nearly the same level. In breech deliveries, the mechanism of the head's jjassage through simple flattened pelves varies as the head engages in a state of flexion or extension. In the former case, while the anterior parietal bone moves downward over the symphysis, the transit-line marked by the promontory upon the posterior parietal bone runs from its anterior inferior angle, just in front of the ear, in an oblique direction upward toward the parietal boss. "When, however, the head enters the pelvis in a state of partial extension, a furrow is formed by the promontory, which runs nearly parallel to the coronal suture. If, finally, the ex- i88 THE PATHOLOGY OF LABOR. tension is complete, and the occiput descends first into tlie pelvis, the marking of the promontory is found between the boss and the lambdoidal suture. In pelves contracted in the transverse diameter, extension of the chin, unless the contraction be slight, proves an insuperable obstacle to delivery. Flexion, however, is the rule, as the resistance which the occiput meets with from the walls of the pelvis tends to direct the chin toward the chest. The Effects produced in Contracted Pelvis by the Pressure of the Child upon the Soft Maternal Tissues.— The body of the child rarely, and only in cases of extreme prolongation of the expulsive period, leaves any traces upon the maternal soft parts. Injurious pressure proceeds almost exclusively from the child's head. As the intrapel- vic organs sustain excessive pressure when of short continuance more easily than that which is moderate but prolonged, the most striking lesions are produced in head presentations. The after-coming head usually passes through the pelvis too rapidly to produce any pro- nounced effects. The pressure is, as a rule, most marked at the brim, where, as we have seen, the contraction is in the generality of cases greatest, and where the pelvic canal is most encroached upon by shuYY) projections. The pressure may be either diffused over the entire periphery of the brim, or it may be more localized at certain definite points. Diffused jiressure occurs in justo-minor jx^lves, or where complete accommodation of the child's head to the form of the pelvis takes place. It gives rise to disturbed circulation in the hypogastric veins, and as a further consequence to transudation of serum, and capillary hfemorrhages in the tissues of the cervix, the vaginal walls, and exter- nal organs of generation. Circumscribed pressure leads to crushing, thinning, and at times to the comjDlete destruction of the tissues acted upon, the extent of the lesion depending upon the intensity and duration of the force exerted. Usually the destructive action proceeds, following the direction of the pressure from within outward — i. e., the injuries are more consider- able, both in degree and extent, in the tissues next to the child's head than in the deeper ones contiguous to the pelvic border. Complete perforation of the tissues during labor is rare. Perforation is com- monly the result of necrosis, the sloughing of the compressed tissues taking place during the puerperal period. The pressure from the promontory is brought to bear, with rare ex- ceptions, upon the cervix uteri.* The supravaginal portion is more * LiTZMANN, Volkraann's Samml. klin. Vortr., No. 23, p. 186. An exceptional instance of pressure ending in perforation of the posterior vaginal wall has been reported by Hofmeier (Zur Casuistik des Stachelbeckens, Ztschr. fur Geburtsh. und Gynaek., vol. x, pp. 5, 6). CONTRACTED PELVES. 489 commonly affected than the vaginal portion. The consequent loss of substance is of a funnel shape, starting from the inner surface, and rarely penetrating through the peritonceum. The coverings of the promontory are not affected by pressure. Pressure from the upper border of the symphysis pubis usually affects the vaginal Avail and the adjacent tissues of the bladder. Fis- tulae resulting are therefore much more commonly vesico- vaginal than utero-vesical. Here, too, the lesions are more extensive upon the inner surface of the utero-vaginal canal, and diminish as they extend out- ward. Thus, the destruction of tissue is greatest upon the cervical and vaginal walls, is less marked upon the posterior bladder wall, while the anterior wall exhibits only faint traces of injury. Pressure from the lateral walls, and from the horizontal rami of the pubes, occurs most frequently in faulty positions of the child's head. Tlius, in brow presentations, the intervening tissues are apt to become clamped between the occiput and the margin of the side wall. Again, when the sagittal suture is directed to the front, and the posterior parietal bone presents, a similar compression may take place between the anterior wall and the child's head. Sharp bony projections from the crests of the pubes are commonly covered by the tendinous attach- ments of the psoas minor muscles. In case of long-continued labor, however, the spinous outgrowths and sharp edges of the crests are liable to rub through their protective coverings, and secondarily the utero-vaginal tissues. Influence of the Pressure of the Pelvis upon the Integuments of the Child's Head. — One of the commonest results of the peripheral pressure of the brim upon the child's head is the production of the scalp-tumor. Its formation is usually associated with compression of the cranial bones. As the bones overlap, the integuments of the engaged portion of the head are thrown into folds. As, however, in consequence of the obstruction in the venous circulation, transudation of serum takes place into the subcutaneous cellular tissue, the folds subsequently dis- appear, and a swelling ensues. It will be seen that conditions favor- able to the production of the scalp-tumor are a soft, easily molded head, and such degree of transverse pelvic contraction as serves to render the circular pressure of the scalp complete. Owing to the lat- ter condition, the scalp-tumor is found more frequently and more de- veloped in justo-minor and generally contracted flattened pelves than in simple flattened pelves with normal transverse dimensions. Usually the tumor does not form until after rupture of the membranes. At times, however, in justo-minor pelves the head may become so fixed at the brim during the first stage of labor that a diffused swelling of the scalp may follow while the membranes are still intact. A scalp- tumor at the brim is of favorable import. It shows that the pains are good. So long as the tumor continues to increase, if the presentation 490 THE rATIIOLOGY OF LABOR. is favorable, the aceommodatiou of the head remains a possibility. The increase of the tumor serves, too, to fix the head at the brim, and favors the overlapping of the cranial bones. It likewise gives to the head the form of an elongated ellipse, a form most favorable to its passage through the contracted pelvic canal. Localized pressure-marks upon the child's head are derived, in the great majority of cases, from contact with the promontory. With less frequency they have their origin in pressure produced by the anterior and lateral pelvic walls and the inward projection, in rachitic pelves, of the cartilage at the symphysis pubis. They consist of round and oval spots and reddened lines, which disappear in the ligliter cases usually in from twelve to twenty-four hours. If the pressure has been long continued, it may give rise to ulceration, or even to complete destruction of the skin down to the periosteum. While not usually danger- ous to the child, in exceptional cases they may become the starting-point of suppuration in the surrounding subcu- taneous cellular tissue, and thus lead to fatal pyaemia. They are found with greatest frequency upon the parietal bones, especially ujDon the posterior one. FIG. 210.-Pressure^mark upon skull, jy^^^.^ ^,^^^^^ ^|^gy ^^.^ situatcd UpOU the frontal, and in very rare instances, finally, upon the occipital and temporal bones. The situation and direction of the red lines depend chiefly upon the manner in which the head enters the pelvis. Thus, in simple flattened pelves, where moderate extension occurs in the normal mechanism of labor, the mark of the promontory runs along the posterior parietal bone, between the boss and the large fontanelle, either parallel to the coronal suture, or at first in the direction of the boss, and then later as flexion occurs forward toAvard the frontal bone (Dohrn). In cases where transverse shortening causes flexion of the head at the brim, the principal point of pressure lies near the parietal boss, and the line runs obliquely for- Avard toAvard the outer angle of the eye, or toAvard the cheek, accord- ing to the extent of the flexion. Sometimes a red line running across the forehead, nearly parallel to the coronal suture, is produced by the pressure of the side Avail. Pressure upon the ophthalmic vein, Avhen it occurs, leads to cedem- atous SAvelling and hyperemia of the lid, and to increased secretion from the conjunctiA'a. Influence of the Pressure of the Pelvis upon the Cranial Bones.— The so-called molding of the child's head, by Avhich it is made to con- form to the size and shape of the pelvis, is chiefly effected by the dis- placements and alterations in the form of the cranial bones. Of the CONTRACTED PELVES. 491 displacements, the most important consists iu the overriding of the bones at the principal sutures. The most common site is along the sagittal suture. Usually the posterior parietal bone is flattened and depressed beneath its fellow. At the same time the curvature of the anterior or presenting parietal bone is increased. In transverse nar- rowing, the occipital bone is depressed along the lambdoidal suture. The position of the frontal bones at the coronal suture is subject to a variety of influences. As a rule, however, they are dej^ressed beneath the parietal bones. Overlapi^ing often does not extend the entire length of a suture, but may exist in one jjart, while in another the bones may occupy the same level. Sometimes a displacement takes place between the two lateral halves of the head in the direction of the occipito-frontal diameter. This movement is supposed to be due to the influence of the promontory, which pushes the posterior half forward when the head is flexed, and backward in cases of partial extension. The compression to which the child's head is subjected, when pro- longed and excessive, is apt to produce disturbed cranial circulation. Rupture of the capillaries which pass from the surface of the brain to the arachnoid sac, and to the sinuses of the dura mater, may give rise to intracranial extravasations. The overriding at the sagittal suture, in extreme cases, may cause laceration of the sinus longitudinalis. Separation of the bones at the sagittal and coronal sutures sometimes takes place while the coverings of the skull remain intact.* In a small jiercentage of cases (7'3 per cent, Litzmann) furrow-like depressions occur. The usual site is along the line of the coronal suture, where they are formed by the promontory. In front a grooved line is sometimes found near the squamous suture, produced by the pressure of the anterior pelvic wall. Triangular depressions (the spoon -shaped depressions of Michaelis) situated upon the posterior parietal bone, between the boss and the large fontanelle, are of still rarer occurrence. They are found chiefly upon the heads of prema- ture children, where they are of sinister import. Actual fracture of the skull in head presentations is extremely infrequent, and is gener- ally due to the employment of the forceps. In breech presentations, lesions of the scalp, owing to the shortness of the time to which the after-coming head is subject to the pressure of the contracted pelvis, are, in two thirds of the cases, absent alto- gether. When they are present they are comparatively trivial, con- sisting of slight swelling of the integuments, and now and then of a red mark left by the promontory. The cranial bones, on the con- trary, when rapidly dragged by the projecting promontory, are pecul- iarly liable to serious injury. Thus, in breech cases, depressions, fract- ures, and fissures of the parietal bones are much more common than * LiTZ.MAXN, Volkmann's Saraml. klin. Vortr., No. 23, p. 191. 492 THE PATHOLOGY OP LABOR. in head presentations. Forcible tractions upon the trunk sometimes lead too to a rupture of the squamous sutures, or even to separation of the condyles from the occipital bones.* Prognosis in Contracted Pelves.— The mortality to the mother is at least twice as great as in normal pelves. The causes of this increased death-rate are to be found in the concurrent action of a great variety of influences. Among the chief of these is the prolonged labor, an event which under all circumstances, especially after the rupture of the membranes, tends to diminish the chances of recovery. This re- sult is due to the strain upon the nervous system from the protracted duration of the associated pain, to the depression of the vital powers growing out of the fasting and loss of sleep which labor entails, to the irritation and crushing of the soft parts, and, finally, to decomposition of the fluids retained within the uterine cavity in cases where access of air has taken place. In contracted pelves we have superadded to these general sources of disturbance the special injurious effects pro- duced by the pressure of the lower segment of the uterus, the vagina, and the soft parts which cover the cavity of the small pelvis between the hard head of the child and the bony walls. As the results of pressure, we have seen that obstruction to the venous circulation, oedema, capillary haemorrhages, superficial lacerations of the mucous membrane, and at localized points necrosis and even complete separa- tion of the interposed tissue may take place. These further lead to metritis, endometritis, parametritis, and perimetritis, which are an- nounced at times during labor, but more commonly subsequent to confinement, by sharp elevations of temperature. When the destruc- tion of tissue reaches the peritonaeum, general peritonitis follows, as a rule. When the necrosed tissues become gangrenous from access of air, the septic poisons generated spread through the cellular tissue, and lead speedily to a fatal termination. Sometimes shock destroys the patient during the first day or two following labor, before local in- flammations have had time to develop. Further dangers to be appre- hended are rupture of the uterus and the pelvic articulations, fistulous communications with the bladder and the rectum, injuries to nerves of the ischiatic plexus, post-partum haemorrhage as a consequence of uterine exhaustion, and thrombus formation in the veins of the uter- ine parenchyma. Even the operative measures resorted to for the relief of the" patients are often new sources of peril, and their employ- ment is to be regarded simply as a lesser evil. For the child the action of the contracted pelvis is even more del- eterious, f The infant mortality, in cases not requiring sacrificial * C. RuGE, Verletzung des Kindes diirch Extraction bei Beekenlage, Ztschr. f. Geburtsh., Bd. i, p. 74. + Spiegelberg puts the mortality of the children at thirty-five per cent {vide Lehr- buch der Geburtshiilfe, p. 464). TREATMENT OF CONTRACTED PELVES. 493 operations, is explained by the long duration of the labor and the prevalence of faulty presentations and positions. In the majority of instances death takes place from asphyxia promoted by the early rupt- ure of the membranes, the complete escape of the amniotic fluid, the prolapse of the cord, the disturbances in the utero-placental circula- tion resulting from the retraction of the nterus upon the surface of the child's body, and sometimes by the premature, separation of the placenta. The prognosis for the child is especially unfavorable in premature labors. This arises not alone from the increased frequency of malpresentations, but from the diminished power of premature children to resist external pressure. Thus, death may take place from direct pressure upon the medulla oblongata through the thin bony coverings of the head, or extensive cerebo-spinal effusions of blood may result from the laceration of the delicate walls of the intracranial and intraspinal vessels. CHAPTER XXVI. TREATMENT OF CONTRACTED PELVES. Cases of extreme pelvic contraction, rendering delivery per vias natwales impossi- ble. — Cases indicating craniotomy or premature labor. — Cases where extraction of a living child at term is possible. — Premature labor. — Version. — Forceps. — Expectant treatment. The resources at the disposition of the accoucheur, in cases of con- tracted pelvis requiring obstetrical aid, are the Caesarean section, the induction of premature labor, craniotomy, forceps, and version. But, before it is possible to form an opinion regarding the treatment best suited to an individual case, it is necessary to first obtain a clear and definite idea regarding the degree and character of the pelvic deform- ity. We have, then, to settle the followiug questions : Has pregnancy advanced to term? If not, does the case call for the induction of abortion or premature labor ? If the end of utero-gestation has been reached, is it possible to deliver the child through the natural passages? Is the child living or dead? If the former, do the interests of the mother require the sacrifice of the child's life ? If the conditions are such as not to render it impossible for a living child to be born, in what way can we best subserve the interests of both mother and child ? The right choice of measures requires not only an accurate apprecia- tion of the advantages, limitations, and drawbacks which inhere to the measures themselves, but the extent to which the mechanical obsta- cles to delivery are heightened or modified by those remoter influences which we have seen are exerted upon the organic processes of labor by the pelvic contraction. , ^94 THE PATHOLOGY OF LABOR. The greater the degree of pelvic narrowing, however, the more cle« cided the influence of the pelvis becomes, and the more definite, there- fore, the treatment. For the sake of convenience it is customary to consider apart the following classes : * 1. Cases of such extreme 23elvic contraction that the attempt to de- liver the child through the natural passages is inadvisable. In these extreme degrees of pelvic deformity premature labor holds out no hope of saving the life of the child, and affords but a trifling advantage to the motlier. If abortion is not produced in the early mouths, the only resource is the Cesarean section or laparo-elytrotomy. The precise limit at which the dangers from delivery through the pelvis rise to the level of or exceed those from the Cesarean section is not easy to deter- mine. It depends partly upon the size and ossification of the child's head, and largely upon the experience and dexterity of the operator. Michaelis, in the case of a dwarf scarcely three and a half feet high, extracted a small child through a pelvis measuring but one inch and a half in the conjugate diameter. The operation lasted two and a half hours. At the end of two weeks the patient was able to resume her household duties, f Dr. Osborn, in the celebrated case of Elizabeth Sherwood, extracted a child through a pelvis measuring, as he believed, but three quarters of an inch in its narrowest portion ! Barnes X ex- tracted with perfect success a child through a conjugate Avhich, he says, certainly did not exceed one inch and a half. It would be easy to go on and extend this list, to show that there is no degree of conjugate shortening that renders it utterly impossible to extract a mutilated child. But the question which we should ask for our guidance is, not what can possibly be accomplished by the skill and ingenuity of the exceptionally experienced operator, who is capable of making whatever rules he likes to govern his own actions, but what is the point at Avhich men in every-day practice need expect to find the dangers from crani- otomy and the Csesarean section rise to nearly the same level. Dr. Parry collected seventy cases of craniotomy in pelves measuring two and a half inches and nnder. Seven had to be terminated, finally, by Cesarean section. Of the seventy women forty-three survived and twenty-seven died. The work was not done by tyros, but by celebrated obstetric surgeons. Thus, the best results of the ablest accoucheurs before the days of antisepsis showed a mortality from craniotomy, in the higher degrees of pelvic deformity, of nearly forty per cent. Un- questionably this heavy death-rate has been lowered by modern aseptic * The limits are those of Litzmann. Vide Ueber die Behandlung der engcn Becken, Volkraann's Samml. klin.

TREATMENT OF CONTRACTED PELVES. 495 methods ; still, in the hands of an operator of limited experience, I be- lieve the Cesarean section, when timely made, offers ordinarily to the mother a better chance of recovery. There are, of course, exceptions to the rule. Most pelves measuring less than two and a half inches in the conjugate belong to the category of generally contracted flat- tened pelves. Where, exceptionally, the transverse diameter is not ma- terially diminished, the difficulties of craniotomy are greatly lessened, and, if at the same time the child's head be soft and compressible, a comparatively easy extraction may give rise to false ideas concerning the real dangers of delivery by the natural passages. These are due chiefly to the fact that the operation has to be carried on within the uterine cavity, when, owing to the contracted brim, no descent of the head is possible. A long operation conducted within the uterine cavity is always fraught with evil. The dangers are not altogether mechanical. Even if serious lesions, such as perforations, rupture of the uterus, and lacerated wounds, are avoided, some contusion of the lower uterine segment is inevitable, air enters freely the uterine cavity, the patient exhibits very commonly the symptoms of profound shock, and the delivery is often followed by post-partu7n haemorrhage, due to uterine inertia. The means employed to check hemorrhage tend still further to depress the vital jDowers. In many cases the uterus remains large and the labor is followed by ca- tarrhal endometritis. This ordinarily mild puerperal affection is apt, owing to the introduction of air and the presence of bits of necrosed tissue, to assume a septic form, and pave the way to a fatal termination. The contiguity of the peritonaeum likewise adds to the formidable character of all suprapelvic operations. When the outlet of the pel- vis alone is contracted, and craniotomy can be performed upon the head after it has entered the vaginal canal, the dangers of extraction are much diminished ; but even when recovery takes place, the un- avoidable injuries inflicted often lead to life-long invalidism. Cases of extreme degrees of the justo-minor pelvis are believed to be excess- ively rare. Certainly tlie whole number reported since Naegele's day may be easily counted on the fingers of the two hands. At full term the labor takes place, provided the general contraction is such as to retain the head at the brim, in one of two ways : 1. The uterus retracts up over the head of the child. If the head does not descend, the vagina is drawn upward and is exposed to injurious tension. Should nothing be done to relieve this condition, the thin vagina is liable to be rubbed through by the pressure it encounters at the brim, and especially at the symphy- sis pubis. Version would here be impossible, and the forceps would only en- hance the risks. Perforation and decerebration would at once diminish the pressure. With little over three inches in the conjugate and four in the trans- verse diameter, the vault of the skull may be broken up with the cranioclast, the chin tilted downward, and the head brought edgewise through the pelvis. In this way, with moderate skill, it would be possible to extract a dead child. 496 THE PATHOLOGY OF LABOR. The operation of laparo-elytrotomy, however, seems so peculiarly fitted to these conditions, that it deserves a trial in the interest of both mother and child. 2. The membranes rupture early, the waters gradually escape, and, as the head does not descend, the uterus retracts down firmly upon the child. A scalp- tumor forms, which fixes the head at the brim and pushes the cervix and lower segment of the uterus before it. Here it would be proper to await for a time the results of uterine action. As the transverse diameter can only be roughly estimated, the head may lengthen out and adapt itself to the pelvic canal. But the delay should not be too prolonged. If, in spite of the formation of the scalp-tumor, the bony head remains unmoved at the brim, it is a question whether it would not be the wiser plan to proceed at once to the Caesarean section. Naegele * reports the history of a dwarf whose pelvis measured but three inches and seven lines in the transverse and three inches in the conjugate. He delivered her with forceps of a five-and-a-half -pound child, but she died on the tenth day. Heim reports the history of a dwarf with three and a quarter inches conjugate and four and three quarters inches transverse diameter. Delivery by perforation and forceps. Rupture of the three articulations.t Spiegelberg reports a case with nearly the same dimensions. Child pre- sented by the breech. Extraction difficult. Perforation of after-coming head. Cephalotripsy. The patient died shortly after delivery. J I have reported a case .where the conjugate was three and one sixth inches and the transverse four and a half inches. Delivery by perforation, the cranioclast, and the crotchet. The patient died on the third day (Trans, of the Am. Gynaec. Soc, vol. iv). Kormann relates a ca.se nearly identical with my own, both as regards its diameters and the existence of a slight lateral obliquity. After over three days' labor the head adapted itself to the pelvis, and the child was extracted alive by forceps. The mother died of peritonitis.* Thus, of five women with generally contracted pelves, in which the conju- gate ranged from three to three and a quarter inches, all died as a consequence of delivery through the natural passages. In cases where the uterus is rigidly applied to the child, and the cervix is undilated, the propriety of laparo-elytrotomy is questionable. The operation is not always a very easy one, and it certainly can not afford to be handicapped by anything which would cause delay in the delivery after the vaginal rent has been made. There are, of course, in so rare a condition, scant statistics in favor of any special plan of treatment. Michaelis reports a case of Mantz's, that of a woman who had a pelvis measuring two inches antero-posteriorly and three inches in the transverse diameter. Here the Caesarean section became a matter of neces- sity rather than one of election. Twice the operation was performed with suc- cess. A third time the result promised to be equally favorable, but the willful and insubordinate conduct of the patient, as late as the twenty-seventh day, led to her destruction. In spite of the fact that in generally contracted pelves craniotomy is nearly * Naegele, Das sehrag verengte Becken, p. 102. •f LOHLEIN, op cit., p. 42.

TREATiJENT OF CONTRACTED PELVES. 497 always practicable, a careful study of the ground convinces me that where there is a diminution of nearly an inch in all the diameters, Csesarean section holds out the best chance for saving the mother's life. 2. Cases hi wliicli tlie pdvic contraction is such as to prevent the hirth of a full-term living child through the natural ^jcissages, but in luhich extraction through the jJ&lvis furnishes the best chance of saving the life of the mother. The choice of measures in this class of cases lies between the Caesarean section, craniotomy, and, where the con- dition of things is recognized early enough, the induction of premature labor. In general terms we are authorized to assume such a degree of disproportion in flattened pelves with the conjugate ranging between two and a half and three inches, and in justo-minor pelves with a con- jugate measuring three and a third inches. In, however, these less ex- treme degrees of deformity, other elements than those of the size of the pelvic canal enter into the formation of an opinion regarding the proper procedure to be selected. I have, myself, in one case, extracted a child weighing six and a half pounds by forceps, without much difficulty, through a generally contracted flattened pelvis with a conjugate meas- uring barely two and three fourths inches. Labor had lasted three days previous to my seeing the patient, which was in consultation. The child's head presented a singular appearance, from the molding it had undergone, having been greatly flattened in its biparietal diameter and enormously elongated in the occipito-mental direction. The child died, however, shortly after birth. The mother recovered, though con- siderable sloughing of the vaginal walls followed the long continuance of the pressure which had preceded delivery. Grenser, in the Dresden Hospital Eeports (1861-'63), gives three cases of children born alive where the pelvis measured two and three quarters inches. In one of these, where the labor lasted twenty-two hours, a living child was born weighing six and a half pounds. If, therefore, labor comes on at full term, an attempt should first be made to gauge the degree of disproportion between the head and the pelvic brim, for not only is it among the bare possibilities that a living child may be expelled through a j^elvis measuring less than three inches, but it is to be borne in mind that in pelvic mensuration even the most expert may make errors of a quarter of an inch. In any case it is well to preserve the membranes as long as possible. Even craniotomy is more easily performed after complete dilatation of the OS. After the waters escape, the lower uterine segment is subjected to injurious pressure between the hard skull and the pelvic rim, the damage done increasing of course with the duration of labor. By early perforation and evacuation of the brain-mass this danger is avoided. But craniotomy should not be performed so long as the hope exists of saving the life of the child. The attempt should be made, at least., before perforating, to form an estimate of the size of the child's 32 V 498 THE PATHOLOGY OP LABOK. head and its relations to the pelvic brim. An approximative result may be obtained by palpating the head through the abdominal walls above the pubes, and, so soon as the cervix is dilated and the head be- comes pressed by the labor-pains firmly against the brim, by introduc- ing the half -hand into the vagina to determine the extent of that por- tion of the cranial vault which has entered the pelvis. When we have ascertained the size of the segment beneath the pelvic border, and the special points of the head which occupy the several pelvic diameters, we are in a position to estimate the size of the portion above the brim, and the mechanical difficulties which remain before the engagement of the head can be accomplished. In shoulder presentations, where, of course, version is necessary, extraction alone should be first tried, and only when it is found impos- sible to effect the delivery of the after-coming head by other means should perforation be resorted to. Schroeder claims to have extracted living children through pelves measuring but seven and a half centi- metres (three inches) in the conjugate.* The induction of premature labor in pelves having from two and three quarters to three inches conjugate diameter possesses the merit of diminished risk to the mother, and affords a chance of saving the life of the child. Below two and three quarters inches the advantages of premature labor may be fairly called in question. To be sure, Kiwisch placed the biparietal diameter of the child's head in the thirtieth week at two and a half inches. Seyfert, however, fixed it at three inches, and later Schroeder obtained nearly three and a quarter inches (8*16 centimetres) as the average between the twenty-eighth and thirty- second week. In point of fact there is too little uniformity in the diameters of fetal heads belonging presumably to the same week of development to make average measurements of any practical utility. It will be seen, however, that, in the higher degrees of pelvic contrac- tion we are now contemplating, the biparietal diameter of the child's head rarely falls within the limits of the narrowed conjugate. Still, it is possible to deliver a living child through a pelvis estimated at two and three quarters inches as late as the thirty-fourth week,f as the head, owing to the pliability of the cranial bones in premature chil- dren, is capable of sustaining a considerable degree of lateral comjires- sion. Naturally the infant mortality in these cases is very large. In addition to the ordinary increased risks attendant upon premature labor, intracranial extravasations of blood from rupture of the deli- cate cerebral vessels are extremely common. Litzmann found in nearly one fourth of his cases (8 : 34) spoon-shaped dejiressions of the skull. Though this lesion is met with upon the heads of living chil- * Schroeder, Lehrbuch der Geburtshiilfe, p. 539. f Wiener, Zur Frage der ktinstlichen Friihgeburt, Arch. f. Gynaek, Bd. xiii, p. 99. TREATMENT OF CONTRACTED PELVES. 490 dren at full term, in the series of Litzmann four of the children were dead at birth, three showed feeble signs of vitality, and in- one .only, which lived but fourteen hours, was it possible to excite the respira- tory process. Thus, the outlook for the child is by no means hopeful ; but, inasmuch as, under three inches, the only operations which come into competition with premtiture labor are the Cesarean section and craniotomy, a small saving of fetal life is a powerful plea in its Justifi- cation. But a stronger argument in its favor is the fact that the in- duction of premature labor offers a milder procedure, which, within certain limits, inures to the benefit of the mother. Below two and three fourths inches the chances of saving the child by premature labor are too slight to be weighed in the balance.* Moreover, unless the child's head happens to be exceptionally small and yielding, approximating the conditions to those which obtain in immature deliveries, craniotomy in the end has usually to be resorted to. Now, as premature labor offers no peculiar advantages in the per- formance of craniotomy, and, as it is attended with certain risks of its own, it is advisable, in very narrow pelves after the twenty-eighth week, to await the normal end of gestation. As the dangers to both mother and child are increased by delay, Barnes has proposed combining version with premature labor in pelves of less than three inches conjugate, as a means of accelerating delivery. Milne by this method extracted a living child through a two and a half inch pelvis. Budin has found by experimentation with artificial 2:)elves that a much less amount of traction force is requisite to drag the head of a premature child through a flattened conjugate by the feet than by forceps in cephalic presentations. The time is probably not far distant when it will be possible to substitute the Caesarean section for craniotomy within the limits of pelvic contraction vmder consideration. Craniotomy requires rigid antisepsis, a sufficient arma- mentarium, and an accurate knowledge of the parturient passage. With the adoption of modern methods in hospital practice, Olshausen reports a death- rate from craniotomy of 5-7 per cent; Cfed6, a death-rate of 8 per cent; and Gusserow reports from Berlin a death-rate of 14-3 per cent, or, excluding cases in which the death had nothing to do with the operation, the death percentage was reduced to 8-3 per cent. Leopold had 71 cases with two deaths; but the latter were from eclampsia, and were not the result of the operation.! For the successful performance of the Caesaiean section there is needed train- ing, adequate preparation, skilled assistants, and that the resistance of the patient * In support of this opinion, which is thoroughly confirmed by my own experi- ence, we have especially the authority of Spiegelberg, Litzmann, and Dohrn. Milne (Premature Labor and Version, Edinburgh Med. Jour., vol. xix. p. 707) re- lates a case where he was successful in a pelvis measuring but two and a half inches. He states, however, that the space in the other diameters of the brim was ample, which was certainly an exceptional advantage, as nearly all pelves with the higher grades of deformity belong to the category of generally contracted rachitic pelves. f Praegek, Der Kaiserschnitt, etc., herausgegeben von Dr. G Leopold. 500 THE PATHOLOGY OF LABOR. shall not be too much weakened by protracted delay. Of 252 cases operated on according to the method of Sanger, between the years 1882-'89, inclusive, 63 (25 per cent) terminated fatally, but in 1890, of 61 cases, only 7 women died (11-4 percent). The possibilities of the improved Csesarean section is, however, best shown in the results obtained by single favored operators. Thus Leopold had had up to August, 1890, 42 cases with four deaths, and in Leipsic, of 36 cases, only 2 terminated fatally. Murdoch Cameron had 9 cases (simul- taneous removal of the ovaries) with the loss of 1 patient. Sanger had 8 cases, Van der Meig 7 cases, and Schauta 15 cases without a death.* 3. Cases in loMch the pelvic contraction does not exceed the limits within which the deliver ij of a living child at term is at least possible. In this category belong the overwhelming majority of all instances of contracted pelvis. It embraces not only cases in which the con- junction of every favorable condition is essential to delivery, but those moderate degrees of narrowing which are chiefly recognizable through the influence they exert upon the mechanism of labor. It includes flattened pelves with a conjugate of three inches and upward, and" justo-minor pelves with a conjugate of over three and a third inches. Below these figures the delivery of living children at full term is too exceptional an event to be taken into account in any attempt at classi- fication. The obstetrical resources for overcoming the mechanical obstacles afforded by moderate degrees of pelvic contraction are the induction of premature labor, craniotomy, forceps, and version. Each one of these measures has its strenuous partisans, who have expended much unprofitable zeal in comparative estimates of their respective values. It is a mistake to regard them as rival pretenders to favor. Indeed, the very conditions which indicate one form of procedure often ex- 'clude the others from consideration. Good midwifery requires a just appreciation of all the auxiliaries at our disposition and a careful study of the circumstances which render them severally appropriate. Premature Labor. — The indiscriminate induction of premature labor in every case of contracted pelvis is particularly to be deprecated. In the first volume of the Archiv fiir Gynaekologie Spiegelberg pre- sented the statistics of 1,224 cases of full-term labor in contracted pelvis, in which the maternal mortality was Q-Q per cent and the in- fant mortality 28 per cent ; while in 271 cases of induced premature labor the maternal mortality was 18*8 per cent and the infant mor- tality 66 per cent. This startling discrepancy is due to the fact that a very large proportion of labors in contracted pelves either terminate spontaneously or require forceps only after uterine action has over- come the obstruction at the brim. If all these minor cases be omitted, a very different result is obtained. Thus, Litzmann found that in flat- * Jahresbencht ueber die Fortschritte auf dem Gebiete der Gcburtshlilfe und Gynaek., Ill Jahrgang, s. 294, und IV Jahrgang, s. 816. TllEATMEXT OF CONTRACTED PELVES. 501 tened pelves measuring from two and three fourths to three and one fourth inches in the conjugate, and in justo-miuor pelves between three and one third and three and a half inches, the maternal mortal- ity after premature labor amounted to 7'4 per cent, while the loss of life in labors at full term was 18-7 per cent.* But, in cases of recov- ery, the advantages of premature delivery are by no means inconsider- able, as, owing to the diminished head-pressure, lesions of the genital canal are of rare occurrence, in striking contrast to the fistulfe, lacera- tions, and cicatrices which so often follow delivery at full term. The prognosis for the child, as shown by the statistics of premature labor in contracted pelves, is decidedly unfavorable. In the restricted class of cases we are at present considering Litzmann found that, though twice as many children were born alive as at full term, the actual number discharged alive from the hospital was about the same. He concluded, therefore, that, Avhile the operation was decidedly indi- cated in the interests of the mother, it offered a dubious advantage to the child. It is, however, always injudicious to draw deductions from hospital statistics alone. Especially is this true of feeble children, born prematurely, whose ultimate chances depend in a peculiar degree upon the care with which they are tended. Dohrn, who objected to the statistics of Spiegelberg and Litzmann, on the ground that the units of which they were composed repre- sented, not parallel cases, but an endless variety of dissimilar condi- tions, proposed, as a fairer way of testing the value of induced prema- ture labor, to compare the results of the latter operation with those of full-term labors in the same patients. Viewed in this way, prema- ture labor in contracted pelves has been found to furnish unexpectedly favorable results. Thus, Dohrn reports nineteen cases, with forty-one children at term, of which thirty-seven died. In twenty-five preg- nancies premature labor was induced, with fifteen living children, f Kiinne and Berthold report eight cases, with twenty-four children at term, of which eighteen died. In eighteen pregnancies premature labor was induced, with thirteen living children. J Still more extraor- dinary is the report of Milne. Six women gave birth at term to twelve children, of which eleven were dead. In the succeeding thirty-eight pregnancies premature labor was induced, and thirty-five children were born living.* The ordinary time for bringing on labor is from the thirty-second to the thirty-fourth week. Most writers now agree that the oi^eration * Litzmann, Ueber den Werth der kiinstlich eingleiteten Friihgeburt bei Beck- enenge. Arch. f. Gynaek., Bd. ii. p. 194. f Dohrn.

Jour., vol. xix. 502 THE PATHOLOGY OP LABOR. should be restricted to pelves measuring less than three and a half inches in the conjugate, whereas above that limit it is best to await the results of spontaneous uterine action. Labor at End of Gestation.— But the physician may first be sum- moned to a case of contracted pelvis after the end of gestation has been reached, or he may at an earlier period have decided against the induction of premature labor. At full term, supposing the head to present, the latter, at the be- ginning of labor, is prevented by the pelvic narrowing from entering the brim of the pelvis, and is usually freely movable. The conduct of the first stage of labor should be directed to preparing the way for the subsequent delivery of the child. To this end every pains should be taken to prevent rupture of the membranes until the cervical dilata- tion has become complete. The patient should be cautioned against restless movements in bed, and from bearing down during the pains. Examinations joer vaginam should be made with great care, and should be avoided except where absolutely necessary. The largest-sized Barnes dilator, moderately distended with fluid, placed in the vagina to exert counter-pressure upon the cervix, is at times of use where the mem- branes have a tendency to protiiide in the form of a narrow cylinder. Attention should likewise be directed to faulty positions and pres- entations of the child's head. Should these be dependent upon a pendulous abdomen, the fundus of the uterus should be elevated, and the normal relations of the uterine axis maintained by a suitably ad- justed bandage. Excessive lateral obliquity should be corrected by placing the patient upon the opposite side. Should transverse nar- rowing require a deep descent of the occiput, this can be furthered by placing the woman upon the side to which the occiput is directed. Where, on the other hand, it is desirable to promote the dip of the forehead, the patient should be made to lie upon the side to which the child's face is turned. The reason of this is obvious, as, when the breech falls to a given side, the ceplialic pole has a tendency to move in the opposite direction. The right use of position as a corrective force depends upon the degree of accuracy with which the character of the pelvic deformity is estimated, and upon a proper appreciation of the mechanism appropriate to the ascertained deformity. Where the sagittal suture looks forward toward the symphysis pubis, so that the posterior parietal bone becomes the presenting part, a firm compress above the pubes may be advantageously employed to press the head backward and approximate the sagittal suture to the median line. The paint',, when weak and inefficient, should be strengthened by the warm vaginal douche ; when the source of exaggerated suffering, they should be mitigated by morphine, by rectal injections of chloral, or by the administration of an anaesthetic. TREATMENT OF CONTRACTED PELVES. 503 Should, by good fortune, the rupture of the membranes bo post- poned until after the completion of cervical dilatation, one of two contingencies may follow : 1. The disproportion between the head and the pelvis may prove to be slight, so that a considerable segment of the cranial vault may be felt below the brim ; then, provided the head en- ters the pelvis in conformity with the mechanical laws dictated by the character of the pelvic deformity, the expulsion of the child may be left to the natural uterine forces. 2. No engagement may take jjlace, the head continuing freely movable at the brim. Under such circum- stances the disjiroportion may be assumed to be considerable. The physician has, therefore, to ask himself whether he shall await the action of the pains, in the expectation that the head will gradually adapt itself to the pelvis, or whether he shall at once jjroceed to per- form version, and drag the child rapidly through the straitened diam- eters. The forceps, as a means of delivery before fixation of the head, should be discarded, not because it can not be employed with sliccess, but because its use, even in the most skillful hands, is extra-haz- ardous. The question of waiting, or proceeding at once to version, is one that will always be decided largely by the individual experiences of the accoucheur. It is, however, vain to deduce rules of practice from the conduct of those who have enjoyed exceptional opportunities, and who usually have developed exceptional skill in some one special direc- tion. It is to be remembered that in contracted pelves, in case the pains prove inadequate to overcome the obstacles to delivery, the alter- natives in head presentations are forceps and perforation. But there are very few experienced operators who have not a more or less per- sonal predilection for either forceps or version, and this unconscious bias exercises, necessarily, to some extent, a determining influence upon their choice. It is well known that there is hardly any subject which has been the source of so much heated controversy as the one at pres- ent under discussion. For the profession at large, however, there is little to be gained from the spirit of partisanship. The general prac- titioner requires instruction not only in the special advantages pos- sessed by each measure, but need,3 to have presented to his attention parallel statements of the dangers and difficulties from which neither procedure is free. Version. — In considering the application of version to the treat- ment of contracted pelves, it is well to state in advance certain points which are rarely alluded to, probably because they are matters of tacit agreement between the contending parties to whose disputes we main- ly owe our present knowledge in relation to the subject. The first of these points is, that the intent of the operation is to save tlie life of the child. In the case, therefore, of a dead child, or of one in which the heart-sounds have notably begun to fail, version 504 THE PATHOLOGY OF LABOR. affords no advantage over perforation. For the same reason the condi- tions must be such as to hold out a reasonable hope of rapid delivery of the child's head, without the infliction of necessarily fatal lesions. Now, there does not appear to be any well-authenticated case of the extraction of a full-term living child after version through a flattened pelvis measuring less than two and three quarters inches in the conju- gate diameter. But even with three, or three and a quarter inches, the result will still depend upon the length of the transverse diameter. Thus, in extreme degrees of the justo-minor pelvis, with the reduction of nearly an inch in all the diameters, the difficulties of delivering the after-coining head, even with the aid of the perforator and the cephalo- tribe, are well-nigh insurmountable. Again, the contraction should be limited to the pelvic brim, for, where it is continuous, or progres- sively increases toward the outlet, the fate of the child is not even doubtful. The other point of importance is, that with three and a half inches and upward in the conjugate, no interference is, as a rule, called for. Since it has become the custom to measure pelves with accuracy, the profession has learned that these moderate degrees of deformity exer- cise their influence not so much in a mechanical way as in the modi- fying effects they produce upon labor. A large proportion of the cases terminate spontaneously. If the pains fail prematurely, the conditions are generally such as to make it an easy matter to deliver with forceps. Difficulties only arise where the head is unusually large and incom- pressible, or in faulty positions, such as the anterior dip of the head in justo-minor pelves, and the presentation of the posterior parietal bone in the flattened varieties. Thus, version is indicated in contracted j)elves only where the child's heart beats with nearly unimpaired vigor and in pelves measuring between two and three quarters and three and a half inches antero-pos- teriorly, with the contraction limited to the brim, and with sufficient amplitude in the transverse diameter. The advantages of version in contracted pelves grow out of the unquestioned fact that the after-coming head passes more readily the contracted brim than the normal head-first presentation. This superior facility is attributable to the entry of the head by its smaller bimastoid diameter. At the same time, the fronto- occipital descends in the transverse diameter of the pelvis. The press- ure of the conjugate is encountered by the bitemporal diameter of the child's head, which measures a half-inch less than the biparietaL Fig. 211.— Base of skull. M M, bimastoid diameter. TEEATMENT OF CONTRACTED PELVES. 505 Tractions upon the trunk of the child bring to bear simultaneously pressure upon the head from many points in the pelvic walls. As a result, bilateral flattening is effected, and a deep groove, usually near the coronal suture, is produced in many cases upon the posterior cranial surface by the pressure of the projecting promontory. The bulk of the head is still further diminished by an overriding of the bones at the sagittal suture, and, where the transverse diameter is insufficient, by the crowding of the occipital beneath the parietal bones. A reduction of the cranial contents is brought about by the retreat of a consider- able portion of the cerebro-spinal fluid into the spinal canal. All these changes are induced rapidly, and are not dependent upon the activity and strength of the uterine pains. The method of performing version and extraction in contracted pelves io, with few modifications, the same as in pelves of normal size. Fig. 212.— Method of employing suprapubic pressure. Head in the pelvic cavity. (Mund6.) In contracted pelves great care requires to be taken lest the arms be- come reflected upward to the sides of the child's head, or crossed upon the neck. To avoid this difficulty it is desirable to introduce the hand over the abdomen of the child, and bring down the arms before the engagement of the shoulders. In extracting the head, tractions may be made upon the lower extremities and shoulders according to the method of Kiwisch, or they may be made with one hand upon the shoulders, while two fingers of the other are inserted into the child's mouth. Provided by either of these methods the relation of the head to the shoulders is such that no twisting of the neck takes place, the amount of force that can be employed without producing 506 THE PATHOLOGY OF LABOR. fat^l lesions is often something astounding. Thus, Eokitansky,* ex- perimenting with the bodies of still-born infants, found the utmost ctrength put forth by two men upon the trunk was insufficient to cause rupture of the vertebral ligaments and separation of the artic- ulations. It is usual, however, to combine pressure from above, exercised by a skilled assistant upon the head through the abdominal walls, with tractions from below. Schroeder states f that this practice is coeval with podalic version. It was known to Cclsus and recom- mended by Ambroise • Pare. It has found warm advocates in Pugh, Wigand, Martin, Kristeller, and in this country in Taylor and Goodell. Both the latter gentlemen have made valuable suggestions regarding the technical management of difficult cases, which are well worthy of special mention. Dr. Taylor X at first draws the body directly back- ward while the head is forced by suprapubic pressure downward and backward into the pelvis. So soon, however, as the head begins to advance, he raises the body of the child and directs pressure upon the head to be made downward and forward in the axis of the outlet. In case of failure or delay, he has sometimes succeeded by intentionally directing the back of the child to the sacrum, and then causing the occiput to be pressed downward and backward into the nearest sacro- iliac space, with the face looking upward, while traction is made in the axis of the outlet. Dr. Goodell,* after first draAving in the direction of the outlet, with the assistant pushing downward and backward, reverses the direction, and sweeps the child's body backward upon the coccyx, the neck likewise being forced downward and backward into the hollow of the sacrum with all one's power. Where the projection of the promontory is not very marked, he likewise recommends as some- times of assistance a pump-handle movement, the range of oscillation extending from the axis of the outlet anteriorly to very firm jiressure on the coccyx posteriorly. It is obvious from the foregoing description that version and ex- traction in contracted pelves expose the child to perils of no insignifi- cant character. Among the lesions Avhich have been observed as a result of the extreme traction force necessary to bring the head rapidly tlirough the narrow brim are fracture of the clavicles, fracture of the humerus in difficult arm-deliveries, lacerations of the sterno-cleido- mastoid muscles, rupture through the substance of a vertebra, extrav- asations of blood into the cavities of the head and trunk, separation of the condyles from the occiput, and of the squamous portion of the temporal from the parietal bones, fractures and depressions of the * RoKiTANSKY, Wieii. med.

TREATMENT OF CONTRACTED PELVES. 507 skull, and rupture of the sinuses of the dura mater.* To be sure, many of these accidents are not inevitably fatal, but they do not by any means furnish the chief sources of danger. These result partly from the respiratory efforts which are always excited by delay in ex- tracting the after-coming head, and partly from the depressing influ- ence exercised uj)on the fetal heart by pressure brought to bear upon the base of the brain, f Having thus made out, with great care, a full bill of particulars, embracing all the acknowledged drawbacks to the j)erformance of ver- sion in narrow pelves, we have next to consider how far these associ- ated evils tend to invalidate the claim of version to be regarded as facile princeps among conservative measures of treatment. The fol- lowing records of the individual exiDerience of competent operators will help us to solve this question. Kormann turned in nine cases of contracted pelves. Seven children were born living and two dead. All the mothers recovered. J Lowenhardt turned in twenty cases of contracted pelves. Seventeen children were born alive, and three dead. Only children that outlived the first week were counted in the successful cases. The mothers recovered.* Groodell reports eleven cases. Seven children were alive at birth, and four were still ; but of the latter, one was extracted through a pelvis measuring only two and a half inches conjugate diameter, and in one the case was complicated by eclampsia. The mothers recovered. Now, not to go beyond these forty cases, we obtain, as the result of version, thirty-one living infants, without the sacrifice of a single mother. A number of the women in whose previous labors craniotomy had been found necessary were de- livered by version of living children. Lowenhardt placed in contrast his own experience Avith the forceps in narrowed pelves presenting degrees of contraction corresponding to those in which he had re- sorted to version. In forty-five deliveries, sixteen children were born dead and five died shortly after birth. Of the mothers, three died, while twenty- one suffered from puerperal affections of greater or less severity. Now, if the foregoing testimony represented the entire truth, there would be no good reason for discussing other plans of treatment. They, in fact, show only how far special training and experience will enable an operator to overcome difficulties by dexterity and address. In the first case reported by Dr. Goodell the child was still-born. In commenting upon the cause of death Dr. Goodell states frankly : * C.

" Much force was needed to extract the head, but it was not made as promptly and efficiently as I have since learned to make it." * Another side of the question has been presented by Borinski,t who, at the instigation of Professor Spiegelberg, collected the statistics of version in contracted pelves from the Breslau Clinic between the years 1865-1872. In all there were ninety-three cases. Thirty-four chil- dren were saved, and fifty-nine were born dead, or died soon after birth. Fifteen mothers lost their lives. This seemingly disastrous showing is capable, however, to a certain degree, of explanation. Thus, twenty of the fifty-nine children born still died before version was attempted. In nine of the cases the transverse as well as the conju- gate was materially diminished. Of the children delivered through these flattened generally contracted pelves, only one, and that a very small one, was extracted alive. Still, there were fifty-eight cases of version in ordinary flattened pelves, with the result that just one half the children were born dead. In only three of the fifteen mothers who died was the fatal result apparently connected with the opera- tion. In the others, death was due to spontaneous rupture of the uterus, placenta praevia, and nephritis, version having been resorted to because of these complications. A considerable allowance should be made, too, in the cases from the Breslau Clinic, for the fact that the greater j^art of them took place in the out-department of the hos- pital, when they were under the charge of midwives, who rarely send for timely aid except in the presence of dangerous complications. In eighteen instances the operation was performed on account of pro- lapse of the cord, and in eighteen instances because of some maternal affection. Forceps. — In presenting this less favorable side of version in con- tracted pelves, it is well incidentally to place in juxtaposition the re- sults of the high forceps operation as given by Dr. Harold Williams (American Journal of Obstetics, January, 1879). Williams collected one hundred and nineteen cases, reported since 1858 where the forceps was applied to the head above the brim. Of the mothers nearly forty per cent, and of the children over sixty per cent, perished. The me- chanical objections to the use of forceps at the brim are obvious. When the head is molded to the contracted pelvis by the natural forces, the head passes the conjugate with its long diameter in the transverse diameter of the pelvis, with the two fontanelles on nearly the same level, and with the sagittal suture looking toward the sacrum. The posterior parietal bone rotates around the promontory, the latter producing a furrow, which runs either along the coronal suture, or at first in front of the parietal boss, and later, as flexion occurs, forward * GooDELL.

TREATMENT OF CONTRACTED PELVES. 509 toward the frontal bone. The bilateral compression of the head is compensated for in part by a lengthening in the fronto-occipital and partly in a vertical direction. The forceps applied in the transverse or oblique diameter of the pelvis prevents the former compensation from taking place. It in- creases the width of the head, and thus adds to the difficulty of jmss- ing the conjugate. Often it disturbs further the normal head mechan- ism by causing premature flexion and rotation to take place. In each of these ways it augments the difficulties of delivery, and renders neces- sary the emi^loyment of an increased amount of traction force. With forceps applied directly to the sides of the child's head I have had no experience, but Dr. Goodell,* who has clearly pointed out the objec- tions to this method in contracted pelves, has shown that they inev- itably produce flexion, and cause the large biparietal diameter to j^ass through the narrow conjugate. So long as the head does not engage at the brim, there is no rivalry between version and forceps. The latter should be placed under the ban as hardly less dangerous than the Caesarean section. Expectant Treatment. — Now, let us suppose that after rupture of the membranes it is decided to resort to neither forceps nor version, but to adopt an expectant course, until circumstances arise which shall render active interference necessary. It is certain that a very consid- erable portion of labors in contracted pelves terminate spontaneously. Winckel f reports twenty-three cases in the Dresden Maternity in 1873, and twelve cases in 1874-'?5. Of the thirty-five cases, two mothers and three children died. Osterloh J reported one hundred and thirty- nine cases from the Leipsic Maternity, between the years 1863-1872, inclusive. There were one hundred and five cases where the pelves measured from three to three and a half inches. Of one hundred and six children, seven died. Of the mothers, four died. In thirty-four cases where the pelves measured over three and a half inches, two chil- dren died. All the mothers recovered. There were, however, forty- two cases in all of puerperal disease terminating in recovery. Borinsky reports from the Breslau Clinic two hundred and thirty-three spon- taneous deliveries in contracted pelves, with one hundred and ninety- two living children. There were ten maternal deaths, but four were from non-puerperal intercurrent affections. Thus, in three large ma- ternity hospitals there were in cases of contracted pelves four hundred and seven spontaneous deliveries with the loss of fifty-three children, and, from puerperal diseases, of twelve mothers. ■ !^ven in pelves meas- * Goodell, Labor in Narrow Pelves, Trans, of the Internat.

If we examine these results, we find that under favorable circum- stances, in all but the extreme forms of pelvic contraction. Nature will do her own work with the least expense of infant life, and with a relatively small maternal mortality. On the other hand, the long-con- tinued pressure upon the parturient canal incident to the molding and adaptation of the head to the narrow pelvis, yields a large contingent of inflammatory affections, which complicate the puerperal period and protract the convalescence. By favorable circumstances Ave mean a presentation and position of the child's head suited to the form of the pelvis, and a sufficient degree of uterine activity. Rectification of a faulty position of the head after the rupture of the membranes is always a matter difficult of accomplishment. In case, therefore, the brow presents, or the head engages with an excessive degree of lateral obliquity (sagittal suture looking forward toward the pubes, or back- ward toward the promontory), in place of wasting time in futile efforts at correcting the malposition, version should be promptly performed. In prolapse of the cord, which pccurs in about six per cent, of the cases, the indication would clearly be version rather than replacement. In eclampsia and face presentations most operators would preferably resort to version. Thus, we have finally the field of controversy between version and other plans of treatment narrowed down to cases in which, after rupt- ure of the membranes, the head remains above the brim, but the con- ditions are such that Nature is capable of overcoming the mechanical difficulties of delivery providing that the labor-pains are sufficiently energetic. There is always an element of chance in this last condition, which, however, is an essential one. If the pains are weak and pow- erless, it may be possible, even hours after rupture of the membranes, when the head has not become fixed, to still accomplish version. More frequently, however, as the head but incompletely fills the lower seg- ment of the uterus, the waters escape, the uterus retracts upon the feetus, the cervix becomes oedematous and tender, and after a time the temperature and pulse rise, betokening the presence of danger. Sometimes the retraction of the uterus ends in the withdrawal of the cervix over the child's head, and, in the failure of the latter to de- scend into the pelvis, the vagina is drawn upward, and subjected to a perilous degree of ^tension. It is easy to see that under such cir- cumstances the time for version is past, and craniotomy is called for. Because, therefore, where labor is left in contracted pelves to the spon- taneous efforts of Nature, in a certain proportion of cases the insuf- ficiency of the labor-pains leads to the necessity of sacrificing the child, there will always be operators who, confident in their own skill, will prefer to turn soon after rupture of the membranes, that they may TREATMENT OF CONTRACTED PELVES. 5H keeja in their hands the control of the delivery. The bulk of pro- fessional men will, on the contrary, so long as spontaneous delivery is probable, prefer to wait, even though by so doing they may eventu- ally find themselves obliged to fall back upon the perforator and the crotchet. AVhen the birth of the child is left to the contractions of the uterus, re-enforced by the expiratory muscles, the physician should assume the role of a watchful spectator. Safety to the mother and the child requires that the time of the passage of the head through the bony canal should not be too prolonged. So long as the head de- scends steadily, however slow the progress may be, in case no compli- cations demand speedy extraction, the physician should await the results of uterine activity. Should the pains grow weak and inef- ficient, they may be stimulated by the uterine douche, the introduc- tion of the catheter into the uterus, and by small doses of ergot or the viscum album, provided the inertia is not the result of pathological changes in the uterine tissues. When the advance of the head ceases, either from failure of the pains or, as in justo-minor pelves, from the growing resistance of the pelvic outlet, the rule should be to relieve the soft parts of the mother as speedily as possible from the pressure of the child's head. Press- ure too long continued ends in cedematous swelling, softening of the tissues, arrest of circulation, and eventually in necrosis and gangrene. When the integrity of the lower segment of the uterus has been im- paired to any extent, perforation should be resorted to, and the child sacrificed to the interests of the mother. If, on the contrary, the changes are insignificant, and the mechanical difficulties not insuper- able, by the use of forceps it may be possible to save the life of both mother and child. But to avoid the first-named cruel alternative, the forceps should be applied so soon as the requisite conditions for its employment are reached. Of course, as the forceps is used solely to save fetal life, in case the feeble heart-action of the child gives warn- ing of impending asphyxia the interests of the mother are to be alone consulted. In estimating the mechanical difficulties to be overcome by the forceps, it is necessary to determine how far engagement has taken place, Litzmann * recommends that the physician ascertain by inter- nal examination, combined with external palpation, both the size of the segment of the cranium below the brim and how much of the head remains to undergo compression before it can enter the j)elvis. In ordinary flattened pelves, Litzmann found that in three fourths of all the cases the pains alone sufficed to overcome the resistance of the brim. W^hen the head had so far descended that the sagittal suture * LiTZMANx, Ueber die Behandlung der Geburt bei engem Becken, Volkniann's Samral. klin. Vort., pp. 715 et seq. 512 THE PATHOLOGY OF LABOR. had passed from three to four fifths of an inch below the promontory, and the boss of the anterior parietal bone could be felt with ease behind the symphysis pubis, extraction with the forceps was a task of no great difficulty, even if before its application flexion had not begun to take place. In generally contracted flattened pelves, it is desirable that the head should be transverse and well flexed, with the posterior parietal bone at least three fifths of an inch below the promontory. With the forehead and occiput resting upon the side walls of the pelvis, the sagittal suture near the promontory, and an ear felt behind the symphysis pubis, the prospects of forceps operations are extremely dubious. In justo-miuor pelves of moderate extent (conjugate three and a half inches), the failure of the pains, which forms the necessity for forceps, is rather the result of the paralyzing effect of the pressure of the bony canal upon the entire circumference of the cervix than of the absolute degree of pelvic contraction. The head descends in a state of comj)lex flexion, with the large fontanelle at the pelvic brim. If, as the head advances, the small fontanelle moves from the median line, and the large fontanelle becomes accessible to the finger, it is likely that the pelvis widens toward the outlet. If the forceps serves only to bring the fontanelle down still deeper, and to increase the de- clivity of the sagittal suture, the opposite condition obtains, which may frustrate the delivery.* In flattened pelves the forceps should be applied as nearly as pos- sible to the fronto-occipital diameter of the head, as the latter needs to descend into the transverse diameter of the pelvis. When applied obliquely it tends to cause premature rotation, which increases the difficulties of extraction. In justo-minor pelves the direction of the blades is of less importance, as the head often descends sjiontaneously in an oblique diameter. Success in high forceps operations depends upon the degree of accuracy with which the tractions are made in the axis of the pelvis. With the long-curved forceps, it is especially diffi- cult to fulfill this requirement at the superior strait. Even when the directions to draw vertically downward are faithfully carried out, a considerable portion of the force is expended in the pressure of the for- ceps upon the soft tissues lying between them and the anterior pelvic wall. In careless hands this pressure is capable of inflicting a great deal of injury, particularly where the blades of the forceps are passed within an imperfectly dilated cervix, and where they project somewhat beyond the child's head. Various devices have been invented to cor- rect this defective working of the instrument. Pajot recommends placing the left hand upon the lock to make pressure backward, while with the right hand tractions are made downward and somewhat for- * LiTZMAXN, Ueber die Behandlunjr der Geburt bei enerem Becken. TREATMENT OF COI^TR ACTED PELVES. 513 ward. I have generally succeeded by exerting a small amount only of force at each traction, watching at the same time with great care the direction of the blades in the pelvis. This method is pretty safe, and in the end generally successful, but often requires a very considerable outlay of time and patience. A pair of straight forceps, as recom- mended by Dr. I. E. Taylor, will often enable one to draw more di- rectly in the axis of the brim, and will succeed when the curved for- ceps have had to be abandoned. Of late I have been in the habit of using Tarnier forceps in high operations, and am able to give it my cordial approval. The blades always swing in the transverse diameter of the pelvis, while the traction force is exerted as nearly as possible upon the center of the child's head. A few trials will convince the most prejudiced opponent of the Tarnier forceps that it will at the superior strait bring the head to the floor of the pelvis in much less time, and with a less expenditure of force, than can be accomplished by other methods. The dangers from the forceps in contracted pelves are due not so much to the pressure it makes directly upon the child's head and the pelvic walls as to the compensatory bulging of the head in its transverse diameter. When the head is fixed at the brim and the for- ceps is applied to the forehead and occiput, it is evident that the only change of form that can take place is in a vertical direction. Safety in delivery requires that there should be no sudden augmentation of the bilateral pressure, which would necessarily deepen the farrow made by the promontory upon the posterior-lying parietal bone, and im- peril the integrity of the maternal tissues confined at the conjugate between the promontory and the pubes. Until, therefore, the head has passed the narrow strait, tractions should be made with moderate force, and with short periods of intermittence. After the head has once descended to the floor of the pelvis the forceps should be removed, and the head be allowed to rotate into the conjugate, then a forceps of any pattern may be adjusted to the sides of the head, should further aid be required to complete delivery. So far we have considered cases in which the cervix was suf- ficiently if not completely dilated before rupture of the membranes. If, as is very common, the membranes rupture prematurely, the diffi- culties and risks to both mother and child are greatly increased. With rupture come, as we have already seen, escape of the amniotic fluid, retraction of the uterus, and interference in the utero-placental cir- culation. With an undilated os externum the cervix is stretched by the head, and its thinned tissues are subjected to pressure from the symphysis and promontory. Delay leads to arrest of circulation and necrosis at the points of pressure, but here version and forceps are alike impracticable. This leaves as the only alternatives perforation and the Cassarean section. Timely aid, therefore, in such cases should 33 514 THE PATHOLOGY OF LABOR. be extended before a dangerous condition is reached. My first prefer- ence just after rupture is the Barnes dilator, which not only serves to expand the cervix, but, when employed promptly, helps to prevent the escape of the amniotic fluid. Next to the Barnes dilator, and of special utility when the waters have already escaped, I would place the long, narrow-bladed forceps of Dr. Taylor for introduction through the undilated os. With it the head can be grasped, and, when made to descend and then allowed to recede in alternation, oftentimes the rounded cranial surface will efficiently act as a dilating body, and se- cure such a degree of expansion as will pave the way for the safe adop- tion of other methods of delivery.

I. The Naegele Oblique Pelvis. This variety of deformed pelvis derives its name from the author who first systematically studied it and called attention to its impor- tance as a cause of obstructed labor. Morbid Anatomy. — The pathological characters peculiar to this va- riety of deformed pelvis are, according to the classical description of Naegele,* the following : 1. Complete anchylosis of one sacro-iliac synchondrosis, or osseous union between the sacrum and one os innomi- natum. 2. Destruction or defective development of the lateral half of the sacrum and smaller caliber of the anterior sacral foramina on the anchylosed side. 3. Diminished breadth of the os innominatum and of the sacro-sciatic notches on the same side. The articular facet of the ili- um, which corresponds to the sacral auricular surface, is less elongated than on the non-anchylosed side. 4. The sacrum is displaced toward the anchylosed side, and its anterior surface is turned in that direction. The pubic symphysis is pushed to the healthy side, and is therefore not directly opposite the promontory. 5. The internal surface of the OS innominatum on the deformed side is flatter than the correspond- ing sound bone, and the linea ilio-pectinea is but slightly curved. * Naegele, " Das schragverengtes Beckcn," Mainz, 1850, p. 7. RARE FORMS OF PELVIC DISTORTION. 515 6. The sound side of the pelvis is not of an entirely natural shape, as is shown by the fact that its ilio-pectineal line is straighter posteriorly, and more curved anteriorly, than in a normal pelvis. ?. The results of the deformities mentioned are : (a) That the pelvis is contracted in that oblique diameter meas- ured by a line passing from the acetabulum of the anchylosed side to the opposite sacro-iliac joint, while the other oblique diameter is not shortened, but even elongated in extreme cases, (b) That the dis- tances between the promontory and either acetabulum, and those be- tween the apex of the sacrum and the spine of either ischium, measured from the affected side, are less than the corresponding distances on the other, (c) That the distances between the tuber ischii of the anchy- losed side and the posterior superior spinous process of the opbosite ilium, and those between the spine of the last lumbar vertebra and the anterior superior spinous process of the diseased side, are shorter than the corresponding distances on the opposite side, (d) That the distance of the superior posterior iliac spine of the anchylosed side from the lower border of the symphysis pubis is greater than that between the Fia. 213.— Naegele oblique pelvis. (From specimen in the Wood Museum.) symphysis and the opposite posterior superior spinous process, (e) That the walls of the pelvic cavity converge below, and that the pubic arch is narrowed and approximated to the type of the male arch. (/) That the acetabialum of the flattened side is directed farther forward than is normal, while the opposite acetabulum looks almost directly outward. We may add that the anterior surfaces of the bodies of the lumbar ver- tebrae are directed toward the anchylosed side. The ilium is higher, steeper, flatter, and reaches farther backward on that side. The pubic arch looks toward the flattened side. The conjugata vera is somewhat elongated. The transverse diameter is shortened at the inlet, and its shortening progressively increases as the outlet is approached.* The * ScHROEDER, Lehrb., p. 596. 516 THE PATHOLOGY OP LABOR. OS innominatum of the healthy side is somewhat displaced outward, and is more markedly curved, hence the venter of the corresponding ilium is directed more anteriorly than that of the anchylosed side.* The deformity is most apparent at the inlet, which is compared by Naegele to an oblique oval figure. The tuber ischii on the anchylosed side is higher, and directed more posteriorly and internally than nor- mal. This description will also apply to the ordinary oblique-ovate pelvis, except so far as the anchylosis, which is the distinguishing feature of the Naegele oblique, is concerned. Etiology.— The essential cause of oblique-ovate pelvis in general is continuous pressure directed against one of its lateral halves, the weight of the trunk falling predominantly or exclusively upon the lower extremity of the deformed side, and leading to displacement and distortion of the pelvic bones. The conditions producing this pre- dominant unilateral pressure are tabulated by Litzmann f as follows : 1. Lateral spinal curvature, usually of rachitic origin. 2. Impeded or entirely abrogated function of one lower extremity. In this case the deformity will affect that side the lower extremity of which is intact. J The impairment or loss of function may result— (r?) from unilateral hip-disease ; {b) from amputation of one lower extremity ; (c) from an old dislocation of the femur upward and backward. 3. Unsym- metrical sacrum, produced by defective development, or by atrophy of one sacral lateral mass — (a) as the result of a defect in the original formation ; (b) as the result of abnormal coalescence of the sacrum and ilium in early life, whereby the growth of both was hindered ; (c) as the result of a loss of substance from caries. Spiegelberg ** calls attention to Lambl's statement that primary asymmetry of the sa- crum may be due to coalescence of the sacral lateral masses and the transverse processes of the last lumbar vertebra, whereby the outward growth of the former is impeded. He also emphasizes || the fact that simple chronic arthritis of the sacro-iliac synchondrosis produces sa- cral asymmetry, without anchylosis, by inducing contraction and atro- phic sclerosis of the contiguous osseous tissue. The continued use of one shortened lower extremity is another cause of excessive pressure upon the corresponding side of the pelvis. When this condition ob- tains, the deformity will be on the side of the shortening. The sacro- iliac synostosis, which has been alluded to as the distinguishing char- acteristic of the Naegele oblique, as contrasted with the other forms of the olbique-ovate pelvis, is sometimes the primary defomity, as will be seen from the foregoing etiological table. The coalescence of the joint- * Litzmann, Die Pormen d. Beckens, Berlin, 1861, p. G9. t Litzmann, op. cif., p. 68. t GussEROw, Arch. f. Gj-naek., Bd. xi, 1877, p. 264. * Spiegelberg, Lehrb.. p. 475.

RARE FORMS OF PELVIC DISTORTION. 517 surfaces is never, however, congenital, because the articulation is fully formed before the appearance of the centers of ossification for the sa- cral lateral masses. Nor can the synostosis be referred to involvement of the joint-surfaces in the process of ossification, since this does not occur in any true joint. The disappearance of the joint-cavity must, therefore, be referable to an inflammatory process, resulting in adhe- sion of the opposed articular surfaces. The inflammation may be either of traumatic or of strumous origin. The results of unilateral pressure upon the pelvis will depend upon the amount of pressure exerted, the resistance of the bones, and the firmness of their connections. Diagnosis. — The attention of the obstetrician will be directed to the possibility of the existence of the oblique-ovate pelvis when the subject limps and presents an inequality in the height of the hips or evidences of antecedent gluteal abscesses. The diagnosis is assured by a physical examination, which shows, in the first place, the distance between the spinous process of the last lumbar vertebra and the pos- terior superior spinous process to be considerably less on the deformed than on the healthy side. The absence of this sign is, however, no proof of the non-existence of the deformity. The distorted ilium is higher than the other, and projects farther posteriorly than is normal. A vaginal examination reveals the straight course of the ilio-pectineal line on the side of the anchylosis, the deviation of the subpubic arch toward that side, a disparity in the distances between the ischiatic spines and the apex of the sacrum, and the deviation of the promon- tory. Naegele * suggested, for the completion of the diagnosis, the application of the following measurements, Avhich are equal on both sides in the normal, but different in the oblique-ovate pelvis : 1. The distance of the tuber ischii of one side from the posterior superior iliac spine of the other ; on the deformed side it is shorter. 2. That from the anterior superior to the posterior superior spine of the other side ; shorter from the anterior spine of the deformed side. 3. That from the spine of the last lumbar vertebra to the anterior superior spinous process of the same side ; less on the contracted side. 4. That from the trochanter major to the opposite posterior superior spinous process ; shorter when measured from the affected side. 5. That from the under surface of the symphysis pubis to the posterior sujoerior iliac spine; longer on the narrowed side. These measurements are only of avail in well-mark^ed cases, and may lead to erroneous con- clusions if other diseases of the bones be simultaneously present. The vaginal examination affords, on the whole, the most accurate results. Mechanism of Labor. — The mechanism of the birth, in an oblique- ovate pelvis, is the following : If the promontory be retreating, the sagittal suture of the fetal cranium enters the inlet parallel to the * Naegele, op. cif., p. 174. 518 THE PATHOLOGY OF LABOR. longer oblique diameter. If, however, the promontory project con- siderably, and is closely approximated to the ilium of the affected side, no portion of the head can be admitted between them.* The cranium will then enter the pelvis most easily with the sagittal suture in the short oblique diameter, and will pass through tbe pelvic canal without rotation. If the pelvis be originally small and the deformity marked, the obstruction to labor may be complete. Should the pelvis, how- ever, be roomy and the promontory retreating, no considerable impedi- ment will be offered to parturition. Prognosis. — It is obvious that the prognosis, for both mother and cliild, is best when the pelvis was originally large, and far less favor- able under the reversed condition. In the latter case the mother very frequently succumbs and the child is only rescued by the Cesarean section. Litzmann's f statistics report the death of twenty-two out of twenty-eight mothers, five of whom perished undelivered, and that of thirty-one children out of forty-one cases. These figures by no means, however, fairly represent the average result, since many cases of slight and moderate deformity escape detection. Treatment. — In a case of extreme obliquity at the Bellevue Hospi- tal, Avhere the distance between the ischia barely exceeded two inches, I induced premature labor at presumably the twenty-ninth week. The child was turned and lived long enough after extraction to receive the rite of baptism. The mother made a speedy recovery. This case affords a striking contrast to those reported by Litzmann. Undoubt- edly, if the obliquity were always recognized at a sufficiently early period of pregnancy, the induction of premature labor would favorably change the prognosis. Very commonly, however, the condition passes unperceived until delay in labor leads to a more careful investigation. In such cases, if the head has entered the pelvic cavity, and the dimi- nution of the space between the ischia is not excessive, a careful at- tempt should be made with the forceps to test the adaptability of the presenting part to the contracted diameter. Violent tractions should, however, be avoided. Studley J has recently reported a case of coxal- gic oblique pelvis in which fracture of the pubic rami upon the right side resulted from forceps delivery. If the disproportion is such that moderate tractions are unavailing to advance the head, or if the child is already dead, perforation should be performed. Craniotomy at the inferior strait is much less dangerous than ^t the brim. If the head fail to enter the pelvis, we have to inquire whether the result be due to absolute deficiency of the pelvic space, or to the fact that the sagittal suture of the head corresponds to the shortened ob- lique diameter. In the first event the case becomes a suitable one for Caesarean section, while in the second version should be performed * Litzmann. Monatsschr. f. Geburtsk.. xxiii, 1864, p. 268. t Ibid., p. 284. X -^m. Jour, of Obstet., 1879, p. 269. RARE FORMS OP PELVIC DISTORTION. 519 with a view to bringing the long cephalic diameter into correspond- ence with the opposite longer diameter of the pelvis. If extraction is then fonnd to be impossible, perforation can still be performed upon the after-coming head. 11. The Kyphotic Pelvis. Morbid Anatomy. — The characteristic deviations of a kyphotic pel- vis from the normal type are due to the unnatural direction in which the weight of the superimposed trunk is communicated to the base of the sacrum, as the result of an existing antero-posterior spinal cur- vature. If a dorsal kyphosis be entirely compensated by a lumbar lordosis, the former may entail no pelvic distortion. As a rule, the deformity is most marked with lumbar and sacral kyphoses, which admit of no compensatory lordosis, and least apparent with remote dorsal kyphoses. The effect of the altered di- rection, in which the weight of the trunk is transmitted to the sacrum, is to force the latter more deeply between the ossa innominata and to rotate its upper portion in a posterior direction. The displacement backward of the inferior extremity of the trunk causes the center of gravity to be thrown far behind the acetabula, and produces a consequent dimi- nution in the obliquity of the pelvis by elevating the anterior pelvic parietes.* The change in the pelvic obliquity is antagonized by the ilio-femoral ligaments, and the result of these opposing forces is as follows : The sacrum is narrowed and elongated by the traction from behind and above, and its upper part is displaced backward. Its transverse concavity is increased and its longitudinal concavity dimin- ished, f The bodies of the sacral vertebrae are on a plane posterior to their transverse processes. The promontory is high and is directed far backward. The upper anterior surface is sometimes convex while the concavity of the lower part is preserved, and an S-like shape is * Laxge, Arch. f.

(Litzmaim.) 520 THE PATHOLOGY OF LABOR. thus imparted to the sacral curve. The higher anterior sacral foram- ina look upward. Owing to the tension of the ilio-femoral ligaments, the anterior inferior spinous processes of the ilium are well developed. The linecB iUo-pectinecB are only slightly curved. The subpubic arch is narrowed. The spines and tuberosities of the ischia are abnormally approximated. Owing to the narrowness of the sacrum, the posterior superior iliac spines are in close proximity to each other, while the spines and crest of the ilium are more remote than in a normal pelvis. The venters of the ilia are expanded and directed to the front. The transverse diameter of the false pelvis is therefore increased, while that of the true pelvis is diminished. The symphysis is prominent, the horizontal pubic rami meeting at an acute angle. At the inlet the oblique and the conjugate diameters are elongated and the transverse diameter curtailed. In the true pelvis the transverse diameters are con- siderably and the antero-posterior diameter slightly shortened. These diameters become still more contracted as the outlet is approached.* If a lumbo-sacral kyphosis be present, the sacrum is shortened and very narrow. If this kyphosis be situated very low down, it may be compensated for by a low lumbar lordosis, which overhangs and ma- terially contracts, the pelvic inlet, f Etiology. — The cause of the spinal curvature resulting in kyphotic pelvis is usually caries of the vertebrae. Diagnosis. — The antecedent history and the discovery of kyphosis will render the existence of this form of pelvis prooable. On more careful physical examination, the shape and position of the sacrum, the short interval between the spines and the tuberosities of the is- chium and the posterior superior iliac spines, the wide separation of the anterior superior iliac spines, the narrow pubic arch and prominent symphysis, the flatness of the iliac venters, and the difficulty experi- enced in reaching the promontory, will establish the diagnosis. The differential diagnosis between a kyphotic pelvis and one deformed by osteomalacia, with which it is sometimes confounded, will be readily made by reference to these distinctive features and to the fact that the transverse diameters of the false pelvis are elongated in a kyphotic pelvis, the reverse obtaining in osteomalacia. Prognosis. — The amount of obstruction offered to parturition will naturally depend upon the grade of the pelvic contraction. The prospects for the preservation of the child's life are not very favorable. In some instances, as in a case reported by Korsch,J there existed a considerable amount of mobility in the pelvic joints, which permits an enlargement of the outlet and facilitates the parturient process.

RARE FORMS OF PELVIC DISTORTION. 521 gravity of the prognosis as regards the mother is the result in most instances, not so much of the mechanical difficulties of delivery, as of her feeble vitality, and the undeveloped condition of her heart and lungs. Again, the spinal disease may be reawakened by pregnancy, and in child- bed may lead to psoas abscess, and other suppurating processes. In many cases the head enters the pelvis with the occiput rotated to the rear. Owing to its smaller size the forehead is better adapted for en- gagement beneath the narrow jjubic arch than the occiput, but perineal laceration is more likely to occur, as the uterine force in fronto-anterior positions is directed to the center of the iDsrinasum. Treatment. — In first pregnancies it is a good rule to await the end of gestation, as experience has shown that Nature may accomplish the delivery, owing to the mobility of the pelvic bones, when the results of the pelvic measurements would seem to indicate this to be impossible. Before resorting to craniotomy, a careful trial should be made in head presentations with forceps. After the head has entered the pelvis the extraction of the child after craniotomy is usually not difficult. Witii the head movable at the brim, neither craniotomy nor version are j)rac- ticable. The Caesarean section is indicated. If the kyphosis is extreme, so that the ribs overlap the ilia, the Porro method possesses the advantage of furnishing more space for the overcrowded pelvic and abdominal viscera. III. SCOLIO-KACHITIC PeLVIS. A brief allusion must be made to the anatomical characteristics of a purely rachitic pelvis, in order to render the differences between it and a scolio-rachitic pelvis intelligible. The leading pathological features of the infantile rachitic pelvis consist in expansion of the sub- pubic arch, prominence and lowering of the promontory, widening and elongation of the sacrum, flatness of the venters of the ilia, between which there is an abnormally wide interval, and in an irregularly rounded, triangular, or kidney-shaped pelvic inlet.* These anatomical features are not altered by the supervention of a scoliosis, but the latter adds to the deformity already existing its own pathological char- acters. The latter combine to produce a marked unilateral asymmetry of the pelvis.f The most ordinary form of scoliosis consists in a deviation of the dorsal vertebrae to the right and a comi^ensating lumbar curve to the left. The adult scolio-rachitic pelvis presents many points of resemblance to the infantile, its leading peculiarities being the following : J The entire pelvis is inclined toward the side of the lumbar curve, and rests chiefly upon the corresponding thigh. The cause of the pelvic asym- * Fehling, Arch. f. Gynaek, Bd. x, 1876, p. 1 ; Ihid., Bd. xi, lg77, p. 173. f Kehrer, Arch. f. Gynaek., Bd. v, 1873, p. GO.

The contracted half of the pelvis is higher and more inclined than its fellow. The sacrum has sunk deep between the ilia, and is narrower upon the side of the lumbar scoliosis. The sacral vertebral bodies are sometimes displaced forward, project- ing beyond the lateral masses. The promontory is displaced toward the contracted side, and the corresponding lateral mass is often narrowed. There is rarely anchylosis of the hip- Joint. The ilium is erect, looks inward, and is narrowed antero- posteriorly. Its crest is higher than that of the opposite side. 'I'he symphysis is displaced toward the uncontracted half of the pelvis. The ilio-pecti- neal line makes a sharp curve inward near the sacro-iliac syn- chondrosis, and then pursues an undulatory course to tlio symphysis, being notably bent inward opposite the acetabu- lum. On the uncontracted side the corresponding line forms a large and rounded arch. The tuber iscliii on the side of the lumbar scoliosis is turned outward. The oblique diameter of this side is greater, but the distance between the sacrum and the acetabulum {distantia sacro-cotyloidea) is much shorter than on the uncontracted side. The plane of the inlet is obliquely cordiform, being contracted upon the side of the lumbar scoliosis and expanded on the other. Exactly the reverse conditions obtain at the pelvic outlet.* The conjugata vera is notably shortened by the pro- truding promontory. The antero-posterior diameter of the outlet, although contracted, still far surpasses the conjugata vera in lengtl.. Other and independent pathological conditions may aggravate tlie obstruction caused by the peculiar deformity in question. Thus, Hu- genberger describes a case of scolio-rachitic pelvis complicated by an extensive sacral hydrorachis.f The peculiar deformity of a scolio-rachitic pelvis obstructs de- livery by so narrowing the space between the acetabulum and the * Leopold, op. cif., p. 10. f HuGEXBERGER, Arch. f.

Rotation is thus prevented, and the delivery must be accom- plished, if indeed it be possible, by the same mechanism obtaining in a justo-minor pelvis, the conjugata vera of which would be here rep- resented by the distantia sacro-cotyloidea, and the transA-erse diameter of which would correspond with the oblique diameter of the uncon- tracted side. IV. Robert's Anchylosed and Traxsverselt Contracted Pelvis. This very rare form of contracted pelvis was first described by Robert in 1843. Its leading characteristics are bilateral sacro-iliac anchylosis and absence or rudimentary development of the sacral lateral masses. The sacrum is consequently very narrow, and only slightly wider at its upper than at its lower extremity. The longi- tudinal and transverse concavities of the bone are nearly or quite ob- literated. In some cases the normal transverse concavity is trans- formed into a convexity. The sacrum is deeply pressed between the ossa inuominata. The posterior «. superior iliac spines are conse- quently closely aj)proximated, and the ilia project far above the base of the sacrum. The promontory encroaches considerably upon the superior strait. The iliac venters are flattened and directed ante- riorly. The linesB ilio-pectinege are slightly or not at all curved, and abnormally approximated. The descending rami of the pubes unite at an acute angle. The ischiatic spines and tuberosities are in close proximity to each other and to the lateral margins of the sacrum. The dimensions of the pelvis are materially altered. The transverse diameter is notably diminished and grows shorter from above downward, so that at the outlet, in marked cases, it is rep- resented by a mere crevice between the ischia and the pubic bones. The form of the inlet is that of a long and narrow wedge with its apex directed anteriorly. The average diameter of the outlet is less than two inches.* The antero-posterior diameter is either of normal length or but slightly shortened, since the projection of the promontory is compensated for by the absence of the normal outward curve of the lateral borders of the inlet. The pelvic canal is deeper than in a nor- FiG. 216.— Robert's pelvis. (Lambl.) * Spiegelberg, Lehrbuch, p. 482. 524 THE PATHOLOGY OF LABOR. mal pelvis.. In some cases there is asymmetry of the two lateral halves of the pelvis. Etiology.— The decisive agency in the production of the deformity under consideration is the narrowness of the sacrum, which is chiefly due to the diminished breadth of its lateral masses, but also in a cerr tain measure to tlie small transverse diameter of the bodies of the sacral vertebrae. Diversities of opinion prevail regarding the connection between the narrowness of the sacrum and the sacro-iliac synostosis. Some authors consider deficient development of the centers of ossi- fication of the lateral masses as the primary event, and the anchylosis as dependent upon this. Others regard the synostosis as tlie primary change which determines the atrophy of the lateral masses,* and vari- ously refer it to inflammatory processes or to arrested development.! In some cases it would seem that the sacrum Avas originally of normal breadth, but was narrowed and united with the ilium by osteitis and arthritis-! The transverse convexity of the anterior sacral surface is explained by the fact tliat the bodies of the vertebrse are pressed for- ward by the weight of the superimposed trunk after the union of the sacral lateral masses with the ilia, and at a time when the connections between the bodi(^ and the lateral masses are still pliable and yield- ing. The close approximation of the ilia and their parallel course are referable to the narrowness of the sacrum and to increased lateral pressure upon the acetabula.* The combined action of these agencies produces the narrowness of the subpubic arch, the acutely angular Junction of the descending pubic rami, the approximation of the iliac crests, and the straight course of the lineae ilio-pectinese. Diagnosis. — The diagnosis is partly based upon the abnormal ap- proximation of the posterior superior iliac spines, wliich almost cover the deeply seated si)inous process of the last liiml)ar vertebra, and upon a similar approximation of the trochanters, of the tubera ischii, and of the iliac spines and crests. A vaginal examination then reveals the parallel course of the descending pubic rami and the striking diminu- tion of the transverse diameter. The differential diagnosis between the Uobert and the kyphotic pelves is based upon the absence of a kyphosis in the former and upon the striking difference between the respective transverse diameters. Prognosis. — This is bad for the mother, inasmuch as labor is com- pletely obstructed by the deformity, and operative interference is always necessary. The Caesarean section is indicated in the interest both of the mother and the child. * LiTZMANN, Die Formen des Beckens. Berlin, 1861. p. 62. t Kehrer, Monatsschr. f. Geburtsk..

This rare form of contracted pelvis was first described by Rokitansky in 1839. Its principal pathological feature consists in the separation of the last lumbar from the first sacral vertebra and in the descent of the body into the pelvis, where the inferior, or in an extreme case the pos- terior, surface of the body of the last lumbar rests upon the anterior sur- face of the first sacral vertebra. The anterior surface of the last lumbar vertebra is directed downward. The anterior surfaces of the fourth, third, and second lumbar vertebrae form an arch, the most prominent part of which, being nearest the symphysis, replaces the normal promon- tory. The result of this displacement is a considerable diminution in the antero-posterior diameter of the pelvic inlet. The descent of the lumbar por- tion of the spine, which is gradually accomplished, is attended by atrophy of the intervertebral cartilages, and frequently by osseous union between the bodies of the lumbar and sacral vertebras. The weight of the super- imposed trunk being now transmitted to the anterior surface of the sacrum, instead of to its base, the pelvic center ^'« ^ir.-spond^^oUsthetic peu-is. of gravity is displaced forward. This is compensated for by a diminution in the normal pelvic inclination, the anterior portion of the pelvis being tilted slightly upward. The pressure upon the anterior surface of the sacrum forces its base back- ward. The posterior superior iliac spines are thus widely separated, and the apex of the sacrum is thrown forward, encroaching upon the antero-posterior diameter of the outlet. In a case cited by Breslau,* the sacro-iliac synchondrosis possessed great mobility. The traction upon the ilio-femoral ligaments, which approximates the tubera ischii, and the lateral displacement of the ilia, due to re- cession of the sacrum, produce a shortening of the transverse pelvic diameter, which becomes more marked in proportion as the outlet is approached. According to the recent investigations of N"eugebauer,f the spon- dylolisthetic pelvis is far from being a very rare anomaly. Thus Neugebauer has succeeded in collecting from various sources twenty- three anatomical preparations and thirty clinical observations made on living persons. * Breslau, Monatsschr. f. Geburtsk.. Bd. xviii, 1861, p. 411. t Dr. Franz Ludwig Neugebauer, Arch. f. Gynaek., vol. xix, p. 441 ; vol. xx, p. 133; vol. xxii, p. 347; vol. xxv, p. 347. 526 THE PATHOLOGY OP LABOR. Etiology.— Neugebauer, who has studied with unwearied patience and zeal the anatomical specimens preserved in the museums of Eu- rope, has shown that in true spondylolisthesis the body of the verte- bra alone is concerned in the forward displacement, the arch, the spine, and the transverse processes remaining in situ. The spinal canal un- dergoes, therefore, an antero-posterior elongation, and the cord is not subjected to pressure. This elongation takes place at the junction of the arch with the body. It does not appear to be due either to caries or an inflammatory process. The original cause of the anomaly Neuge- bauer attributes in many cases to a congenital separation of the arch from the body of the fifth lumbar vertebra, due to defective ossification, in rare instances to traumatic fracture of the sacral articular processes, and in some cases probably to fracture of the arches due to trauma- tism. The latter cause he admits, however, to be hypothetical, as where fractures have been observed it is not possible to determine whether they occurred primarily, or whether they resulted secondarily from the strain placed upon them in the forward and downward move- ments of the vertebral body. In a few instances the etiology remains unsolved. The deformity never occurs suddenly, but progresses slowly under the pressure of the trunk until the gliding movement is arrested by bony union between the lumbar and sacral vertebra. Repeated pregnancies furnish me- chanical conditions favoring the spondylolsthesis, though pregnancy is not an essential element in the causation, as the accident has been ob- served in males. Diagnosis. — As a result of the deformity, the abdomen is protuber- ant and the thorax is sunken between the prominent iliac crests. The trunk, therefore, appears shortened, while the extremities are relatively of disproportionate length ; the width between the troclianters is in- creased ; the nates are flattened and pointed below with deep lateral depressions, so that the posterior aspect of the buttocks possesses a heart-shape and the base of the sacrum and the posterior superior spines of the ilium are prominent. Along the spine a deep lumbo- dorsal furrow is observable, and, owing to the diminished pelvic incli- nation, the external genitals are directed to the front. The gait of patients suffering from spondylolisthesis is peculiar. The steps are short, the toes are but slightly turned out, and the footprints follow one another in nearly a straight line. It is not, however, easy to de- termine by external examination alone the difference between spon- dylolisthesis and a deep-seated lumbo-sacral kyphosis. The internal examination is best made, according to Neugebauer, in the upright or lateral position. To determine the existence of the angle formed by the projecting lumbar vertebra, the finger should be introduced along the anterior vaginal wall in the axis of the superior strait directly to the spinal column, and then should be passed downward to the seat of RAKE FORMS OP PELVIC DISTORTION. 527 displacement, carefully feeling in the descent the spinal vertebrse and the extent to which the spine covers the pelvic brim. Olshausen * first announced the fact that the point of division of the abdominal aorta into the common iliac arteries is displaced down- ward by the descending lumbar vertebras to such an extent as to en- able the palpating finger, introduced into Douglas's cul-de-sac, to de- tect pulsation in these vessels. Hartmann f was enabled to feel the point of the aorta's division on the upper border of the fourth lumbar vertebra, and Breslau J felt a pulsating vessel in the same situation. Neugebauer states that this displacement is not pathognomonic, but may be observed in other instances of spinal lordosis. The spondylo- listhetic lordosis may be mistaken for the sacral deformity peculiar to a rachitic pelvis. Breisky ** suggests that this error may be avoided by attention to the fact that in the rachitic pelvis the sacral lateral masses pass outward from the projecting promontory, while in spondylolisthe- sis one can feel at the pelvic inlet only the rounded prominence of a single vertebral body without laterally expanding wings. The pro- jecting angle made by the body of the last lumbar vertebra with the anterior surface of the sacrum is also easily accessible to palpa- tion. Prognosis. — The prognosis in cases of the spondylolisthetic, as in other forms of contracted pelvis, depends upon the degree of the ob- struction of the brim, and such collateral conditions as the size of the child, the strength of the pains, and the position of the head at the point of entry into the pelvis. Other things being equal, a deviation of the spine from the median line is a favorable condition. Swedelin,! from a careful study of the clinically observed cases, concludes : 1. That where the false conjugate measures above 3| inches no dis- turbance of labor is to be anticipated. 2. When the false conjugate measures from 3 to o^ inches, preg- nancy may be permitted to proceed to term, as labor at term may be expected to terminate favorably for both mother and child, without the intervention of severe operative measures, 3. Labor at term, with a false conjugate measuring between 2^ to 3 inches, is extremely dangerous for the child ; the prognosis for the . mother is likewise bad. 4. With less than 2^ inches in the false conjugate, extraction of the child without craniotomy is hardly possible. * Ohlshausen, Monatsschr. f. Geburtsk., Bd. xxiii, p. 204. t Hartmann, Monatsschr. f.

In multiparse the prognosis is the more serious in cases where the previous labor was difficult. He advises, therefore : 1. Induction of premature labor at the thirty-second week, with a false conjugate of less than 2f inches. 2. Induction of premature labor at the thirty-second week Avith a false conjugate measuring between 2| and 3i inches. 3. Between 3^ and d^ inches, it is best to await the end of gesta- tion, unless the feeble condition of the patient contra-indicates a wait- ing policy, in which case premature labor should be induced in the thirty-sixth week. 4. Premature labor is not indicated with a false conjugate exceed- ing 3^ inches. 5. If the end of gestation has been reached with a false conjugate of less than 2f inches, wait until danger threatens the patient, and then decide between craniotomy and the Cassarean section. 6. With a false conjugate of less than 2J inches, the Caesarean sec- tion is called for. VI. Funnel-shaped Pelvis. This term has been applied to two varieties of deformed pelves, both of which are exceedingly rare. The inlet of the first variety is either normal or but slightly contracted in all its diameters, but its canal is gradually and progressively narrowed as the outlet is ap- proached. The contraction affects chiefly the transverse diameter ; but either this alone, the antero-posterior diameter alone, or both to- gether, may be shortened. The lateral pelvic Avails converge consider- ably, particularly in the vicinity of the outlet. The descending rami of the pubic bones are closely approximated, so that the subpubic arch forms an acute angle. The spines and tuberosities of the ischia are in close apposition.* The sacrum is elongated and but slightly curved, its position resembling that of the sacrum in a kyphotic pelvis. It will be seen that these deformities produce a close resemblance to the typical male pelvis. Pelves of this variety are frequently some- what unsymmetrical. The second variety of the funnel-shaped pelvis is so exceedingly rare as to require only a passing notice. In this instance the deform- ity is exactly the reverse of that just described, the inlet being very narrow in either one or in all of its diameters, wliile the outlet is of normal size or even abnormally wide in one or more directions.f Etiology. — The causes of this deformity are imperfectly under- stood. The former variety is believed to be due to arrest of develop- * PoppEL, Monatsschr. f. Geburtsk., Bd. xxviii, 18G6, p. 234 ; Braun, Arcli. f. Gynaek., Bd. iii, 1870, p. 154. t Spiegelberg, Lelirbuch, p. 473. RARE FORMS OP PELVIC DISTORTION. 529 ment in the sacral lateral masses and to other causes co-operating to alter the direction in which the weight of the trunk is normally trans- mitted to the sacrum. This view seems to be confirmed by Schroeder's observation that the funnel-shaped pelvis is of unusual frequency in a certain German province, where the children are carried upon the back in a position intermediate between the erect and the recumbent pos- ture.* The weight of the body would in this case be transmitted to the sacrum from above and in front, as in the kyphotic pelvis, rather than from behind and above, as is the case in a natural position, and the pelvis would neither acquire its normal anterior curvature nor its posterior inclination. The same theory explains the failure of the sacrum to exert its usual wedge-like action in separating the ossa in- nominata, and accounts for the consequent approximation of the tubera and spines of the opposite ischia. Diagnosis. — In cases of slight deformity the diagnosis is difficult. In well-marked cases the approximation of the ischial tuberosities, the slight divergence of the pubic rami, and the acute subpubic angle are readily appreciated. Arrest of the head after it has already descended into the true pelvis will often be the first circumstance serving to di- rect the attention to the possible existence of funnel-shaped pelvis. Pelvic menstruation, with particular reference to the distance between the spines of the ischia and to the width of the sacrum, will establish the diagnosis. Prognosis. — In the slighter grades of funnel-shaped pelves, the prognosis is not grave. If the deformity be marked, however, the child's life must almost invariably be sacrificed ; and gangrene of the maternal soft parts, with resulting cicatrices and fistulas, or even with caries of the pubic bones, may be the consequence of the excessive pressure to which these tissues are liable. In a case reported by Schar- lau the lesions already mentioned were accompanied by perforation of the fundus uteri from gangrene, and by rupture of the right sacro-iliac artery. f The treatment consists in the induction of premature labor, or, at term, in a cautious attempt to deliver with forceps. Should moderate tractions fail to advance the head, perforation and extraction with che cranioclast should be resorted to. VII. Pelves deformed by Osteomalacia. Osteomalacia is almost confined to females, and appears, ordinarily, in the puerperal state. It usually attacks fully developed bones, but may, rarely, affect them during their period of growth. It is gener- ally observed in multipara?, although primipara? are in exceptional cases * ScHROEDER, Lehrbiich, p. 582. f ScHARLAU, Monatsbchr. f. Geburtsk., Bd. xxvii, 1866, p. 1. 34 530 THE PATHOLOGY OF LABOR. Fig. 218.— Osteomalacia. (Specimen from Woofl's Museum.) its victims. Each succeeding pregnancy is usually attended by a pro- gressive development of the disease, which may, however, become non- progressive, or even be completely and permanently arrested.* In a case of this kind the bone is restored to its normal histological state, al- though its deformity remains. Osteomalacia may involve the entire osseous system, or be confined to individual bones. In the latter case the long bones and the vertebras are most frequently diseased, f In puerperal osteomalacia the pelvis and the vertebra? are predominantly and often exclusively affected. The disease is regarded as an osteomye- litis, which, beginning in the center of bones, advances toward their pe- riphery. The essential pathological process consists in the absorption of calcareous matter, through the Haversian canals, and in the sub- stitution of hypertrophic medullary tissue for the softened osseous struct- ures. The natural result of the changes is great friability or pli- ability of the bones, according to the stage reached by the disease, and their consequent distortion by compression or traction. The bones are of very light weight. Their transverse section reveals a porous, diploe-like structure. Their outer, hard lamella is exceedingly thin, or entirely absent. The bones are of a wax-like softness, being readily cut and molded. The term rub- ber or elastic pelvis has been applied to those pelves whose bones have reached this stage of degeneration. In the most advanced cases the osseous tissue is represented merely by membranous sacs of peri- osteum inclosing medullary tissue and fat. Morbid Anatomy. — The osteomalacic pelvis presents the following pathological anatomical features : The sacral lateral masses are very narrow, and the entire bone, which is displaced downward between the ilia, is sharply curved. The promontory is accordingly deeply do- pressed and approximated to the symphysis as well as to the apex of the sacrum, which is itself displaced forward and curved upward. The promontory and the apex of the sacrum may, in marked cases, almost touch each other. The ilia are placed almost vertically. Their crests are elongated and sharply curved. The anterior superior spinous pro- cesses are approximated. The posterior superior spinous processes are in the same plane with the posterior surface of the last lumbar spinous * WiNCKEL, Monatsschr. f. Geburtsk., Bd. xxiii, 1864, p. 321. f LiTZMANN, Die Formen des Beckens, Berlin, 1861. RARE FORMS OF PELVIC DISTORTION. 53I process. The iliac fossa is divided, near its middle, by a vertical fur- row, which may be bifurcated at its lower end. A prominence corre- sponding to either acetabulum encroaches more or less upon the pelvic canal. In grave cases these prominences may even come in contact with the promontory. The pubic bones are in close apposition, and the pelvic inlet is consequently pointed anteriorly, while the symphysis is prominent and sharply angular. The ascending rami of the ischia and the descending rami of the pubes are apj)roximated, and the sub- pubic arch is partly or completely abolished. The tuberosities of the ischia are approximated. The deformities described may be asym- metrical. The pelvic canal is greatly narrowed, the outlet usually suffering more distortion than the inlet. The pelvic inlet and canal are of triangular form, and assume, in the highest grades of the dis- ease, the shape of the letter Y. The transverse diameter is always contracted, and its shortening is more marked as the outlet is ap- proached. The approximation of the ischial tuberosities and of the pubic bones, together with the anterior displacement of the apex of the sacrum, sometimes ahnost obliterates the outlet. Etiology. — The etiology of this pelvic deformity may be divided into — 1. That of the original disease ; and, 2. That of the resulting distortions. 1. The causes of osteomalacia are obscure. Cold and damp dwellings, insufficient air and light, inadequate aliment, and ex- posure are cited as exciting causes ; * but it seems probable that these alone are insufficient etiological agencies unless some undetermined predisposing cause be already in operation. The disease is sometimes observed to assume an endemic form, particularly in countries where the above-mentioned exciting causes prevail, as, for instance, in the Rhine provinces and in some parts of Italy. In the United States it is only observed in isolated cases, usually in persons of foreign birth. 2. The immediate causes of the distortions are found (a) in the altered structure of the bones, and (b) in the various forces acting mechani- cally upon them, (a) The lime-salts, which impart stability to normal bones, are greatly diminished. Although it is not definitely known by what emunctories they are removed, it is probable that they are chiefly excreted by the kidneys. Gusserow states that the proportion of lime-salts in the milk of women suffering from osteomalacia is ab- normally large.f Pagenstecher opposes this view.J (b) Tlie distor- tions are chiefly produced, when once softening of the bones has oc- curred, by the muscular traction and by the pressure exerted upon the pelvic walls. This pressure will vary in direction and intensity with the different positions assumed by the patient. If the dorsal decubitis be long maintained, the sacrum is displaced forward and the ilia are * Hennio, Arch. f. Gynaek., Bd. v, 1873, p. 519 ef seq. t Gusserow, Monatsschr. f.

In the erect position the sacrum is forced downward and for- ward, dragging with it the posterior parts of the ilia, and increasing the bend in the iliac fossa. The same effect is produced by the upward and backward pressure exerted upon the acetabula by the femoral heads. In the lateral position the ilia are forced inward, and the transverse pelvic diameter is thus diminished. In the sitting posture the apex of the sacrum and the tubera ischii are forced upward. The deviations referred to above result from excess of pressure in some given direction, or from unequal jn-ogress of the disease in the various bones. Diagnosis. — In the earlier stages the history of violent pains in the pelvis and lower extremities will direct attention to the existence of osteomalacia, and careful mensuration will reveal beginning distortion. Pelvimetry is most satisfactorily performed during anaesthesia, which permits the introduction of the entire hand within the pelvis. If the disease be more advanced the diagnosis will be based upon the above- mentioned morbid anatomical features, chief among which are the prominent pointed symphysis, the parallel pubic rami, the approxima- tion of the tubera ischii, the accessibility of tlie i)romontory to palpa- tion, the curvature of the sacrum, and the folding of the ilia. 8pie- gelberg insists on the value of the pliability of the pelvic bones as an aid to diagnosis.* The pliability, although slight during pregnancy, is more marked in labor. Its first sign is great sensitiveness to jiress- ure over tlie symphysis.! Its grade can be decermincd by the method recommended for pelvic measurements. Prognosis. — The prognosis for the mother is very bad. The ma- jority of patients succumb to the effects of pressure in labor, to the results of operative interference, or to the exhaustion attending the almost invariably progressive disease. Amelioration of the symptoms and signs sometimes occurs when conception does not recur. In very exceptional cases not only may the pathological process be arrested but the normal histological character of the bone restored, (a) Even in such cases, however, the pelvic deformity remains unaltered, and would sadly cloud the prognosis if conception should recur. The prognosis for the child is more favorable. In the beginning of the disease, and in cases of pliable pelvis, the child maybe born uninjured. J In more advanced cases a fair prospect of preserving its life is afforded by a resort to the Cesarean section. The treatment will depend upon the results of a careful exploration * Spiegelbercj, Lehrbuch, p. 480. t WiKCKEL, Monatsschr. f. Geburtsk. Brl. xxiii, 18G4, p. 81. X Kezmarszky, Arch. f.

This should determine, first, whether it is possi- ble to extract a living child through the natural passages ; or, second, where that is out of tlie question, whether it is possible to deliver after craniotomy. In estimating the chances it will be necessary to take into consideration the pliability of the pelvis, it having been found possible in many case§ of advanced softening to open up the pelvic canal with the hand and deliver by version. Lazzati and Casati, in Milan, found it was only necessary to perform Ctesarean section twice in sixty-two cases. Litzmann in 1857 reported forty Cajsarean sec- tions in eighty-five cases; fifteen years later Hugenberger reported but four Csesarean sections in twenty-five cases (Spiegelberg). Lately Porro's operation has been proposed by Levy in osteomalacia as a cura- tive measure ; but of this further experience is necessary. Pseudo-Osteomalacia. — It is possible for a rachitic pelvis, in which the rachitic changes are excessive, to present a shape similar to that in osteomalacia. This form is, however, distinguishable from the latter through the hardness of the bones, their smaller size, the greater dis- tance between the anterior superior spinous processes, and the traces of rickets in other parts of the skeleton. VIII. Pelves deformed by Exostosis, or by Osseous Tumors. Fractures of the pelvic bones may be the source of pelvic deform- ity, either by producing permanent displacement of the bones, or by leading to such extensive deposits of callus as to obstruct the parturient canal. Multiple exostoses of the pelvic bones are of comparatively frequent oc- currence, and are usually attended by multiple exostoses of the entire osseous framework.* The pelves in which they are foiind are, as a rule, either of the oblique-ovate or of the rachitic variety, and the combination of these deform- ities is naturally a serious one, since the maternal soft parts are liable to con- tusion and perforation at many points during parturition. The ilio-pectineal eminence is sometimes so unusually prominent and sharp as to offer an obstacle to parturition. The same is true of the pubic crest and spine.

They usually spring from the sacrum or from the symphysis,* and are of various dimensions. Some of them almost completely conclude the parturient canal, and may constitute formidable obstructions to delivery. In this connection may be mentioned as of rare occurrence anch}-- losis of the coccyx, a condition which materially shortens the antero- posterior diameter of the outlet. IX. Absence of the Symphysis. In this variety of deformed pelvis the symphysis is congenitally absent, and is replaced either by strong fibrous bands extending be- tween the opposing surfaces of the pubic bones, or by the muscles and connective tissue of the perinaeum. It is accordingly designated by Litzmann the split pelvis, f Morbid Anatomy. — It is usually attended by ectopia vesicae and by hiatus of the abdominal wall in the linea alba. In rare cases an ab- dominal hiatus exists without a corresponding opening in the bladder. If the split be located immediately below the symjjhysis, the urethrals involved rather than the bladder, and is sometimes so defective that cystocele may occur through the abnormal opening in its anterior wall. J Both the external and internal organs of generation are imjjorfectly developed. If the anterior wall of the urethral canal be absent, the mucous membrane of the fundus vesicae is directly continuous with that of the vaginal orifice. In other cases the bladder is only sepa- rated from the vulva by a narrow bridge. Tlie vulva and anus are often situated more anteriorly than normal, and the perinaeum is thus diminished in thickness. The clitoris is bifurcated or absent, the nymphfe are imperfectly developed, and the defective labia majora widely separated. The vagina may be imperforate or partially oc- cluded by a transverse septum. The uterus may be double and the ovaries rudimentary.* In a case reported by "Winkler, separation of the pubic bones had occurred at the symphysis, as the result of an accident in early life, and they were only connected by bands of fibrous tissue.! The sacrum of a split pelvis is displaced forward between the ilia, its vertical and transverse curvature diminished, and its length increased. The iliac fossfe are widely separated. The entire pelvis is greatly flattened antero-posteriorly, and strongly resembles the rachitic pelvis. Etiology. — The cause of the existing deformity is found in the * Harris, Am.

The natural resistance to the sepa- ration of the lateral pelvic parietes offered by the normal symphysis being wanting, the weight of the superimposed trunk naturally forces them apart posteriorly, while the pressure of the femora bends them inward anteriorly. In some instances anchylosis of the sacro-iliac joints occurs, as a consequence of an arthritis resulting from the in- creased pressure thrown upon them by the lateral displacement of the ossa innominata.* In other cases sacro-iliac synostosis is not present, but the firmness of the pelvis is, nevertheless, such as to admit of un- impeded locomotion.

Atresia of the Genital Canal. Obstruction of the Gen- erative Passages by Morbid Processes in Neighboring Tissues. I. Vulvar Atresia. — The term atresia., as here employed, implies either partial or complete obstruction of the genital canal. Atresia of the hymen is of more frequent occurrence ' than any other variety of vulvar stenosis. f Unless unusually thick and rigid, however, the atresia offers only a trifling obstruction to delivery. Its chief importance is owing to the fact that it leads, in the unimpreg- nated state, to retention and accumulation of the menstrual fluid, which may occasion serious inflammatory, septic, or reflex nervous phenomena. Adhesions of the labia majora and minora constitute other forms of incomplete vulvar atresia. Their causes are often ulcerative processes resulting from injuries, or developed during the course of variola and other constitutional diseases. Under these circumstances they may consist of unyielding cicatricial tissue, which either ruptures in labor, or, forcing the head backward, leads indirectly to the exertion of injurious pressure upon the recto-vaginal septum or upon the peri- * Freund, Arch. f.

If the atresia be congenital, and not the result of cicatricial changes, it will rarely constitute an impediment to parturition. When the entrance to the vagina is very narrow, without exhibiting any pathological condition, as is often the case with aged primipar*, it may be extensively lacerated in labor. A rigid perinaeum is also well known to constitute a serious impediment to the normal progress of parturition. (Edema of the vulva, usually attendant upon albumi- nuria, produces atresia, and the oedematous labia and perinaeum may become gangrenous from excessive pressure during labor. Vulvar hsematoma, or thrombus, if formed, as it rarely is, before delivery, likewise obstructs the outlet of the parturient canal. A similar effect is produced by cancers and polypi of the vulva, which are, however, not often of sufficient size to occasion serious difficulty. II. Vaginal Atresia. — This variety of stenosis of the generative passages is either congenital or accidental, complete or incomplete. (a) The congenital form may be either incomplete, in which case the stenosis sometimes affects the entire length of the vagina, and sometimes forms a circumscribed ring-like stricture,* or it may be com- plete. In either case the atresia is due to arrested embryonic develop- ment, which, in the latter instance, must have originated at a very early period of fetal life. Congenital narrowing of the vagina independent of any morbid process or any arrest of development is often observed, but is of trifling consequence, being overcome by the hypertrophy and relaxation accompanying pregnancy, and by the natural expulsive forces. Absence of the vaginal canal does not necessarily imply ab- sence or imperfect development of the uterus. Fallopian tubes, or ovaries. (b) Accidental vaginal atresia may be either complete or partial, but is ordinarily of the latter form. Both varieties result from the cicatrization following superficial or deep ulceration produced by con- stitutional diseases or by local injury. The diseases during the course of which vaginal ulceration occurs are chiefly diphtheria, variola, ty- phoid fever, cholera Asiatica, and syphilis. The mechanical injuries productive of vaginal stenosis are mainly those incident to protracted labors, to the unskillful employment of instruments, or to the improper performance of obstetrical operations ; but caustic local applications, pessaries, excessive coition, or any local irritant of sufficient intensity to produce ulceration, may lead to the same result. In consequence of impaired vitality, ulceration and stenosis of the vagina may follow normal labors unattended by any injurious pressure. Complete acci- dental vaginal atresias are produced, as a rule, by grave mechanical injuries, but may also follow the acute infectious diseases enumerated above, although the ulcerations attending the latter usually lead to only partial stenosis. * ScHROEDER, Lehrljuch, Gte Aufl., p. 491. ABNORMALITIES OP THE SEXUAL ORGANS. 537 Mention may properly be made, in this connection, of various mor- bid conditions involving tissue adjoining the vagina and resulting in diminution of its caliber. Simple prolapse of the anterior vaginal wall sometimes occurs,* and, assuming an oedematous condition owing to the obstruction of its circulation, decidedl}- constricts the parturient canal. Cystocele fre- quently accompanies the prolapse of the anterior vaginal wall. If the bladder be distended with urine, the cystocele presents a tense fluctu- ating tumor of sufficient size to completely occlude the vagina. The subjective symptoms of this condition are intense pain with vesical tenesmus and dysuria. In some cases the cystocele is retracted by the longitudinal cervical contractions, or it may be forced still farther downward by the advancing foetus, producing obstructed labor and even ruptute of the vesico-vaginal septum. Prolapse of the posterior vaginal wall with rectocele produces vaginal stenosis, especially if the rectum be filled with impacted feeces. This condition is easily recognized by the characteristic feeling of the fecal mass, which admits of indentation by the palpating finger. Retention of urine becomes oftentimes a grave complication of parturition, in that the distended bladder, by displacing the uterine axis, prevents the jjresenting part from engaging in the superior strait. The pressure it exerts upon the uterus also interferes with the efficient contraction of that organ. The diagnosis is based upon the presence of a tumor near the uterus, and often situated laterally from it, which disappears as the urine is withdrawn through a catheter. The intro- duction of the latter is often extremely difficult, owing to the com- pression of the urethra and the retraction of the meatus urinarius within the vagina. Vesical calculi, if of any considerable magnitude, seriously obstruct the caliber of the vagina by becoming impacted in the base of the bladder, the urethra, or a cystocele, between the foetus and the pelvic walls. Under these circumstances not only is the labor obstructed, but contusion and rupture of the soft parts, resulting in vesico-vaginal fistula, may ensue. Impacted calculi have sometimes been mistaken for exostoses ; f but attention to the fact that they are immovable during the pains and movable in the intervals, together Avith the use of the vesical sound, will prevent this error. Vaginal hernia consists of a sac formed by the protrusion of the vaginal wall, lined with the parietal peritonaeum and containing some of the abdominal or pelvic viscera. The organs usually present in the sac are coils of the small and large intestine, the middle portion of the rectum with its elongated meso-rectum, parts of the omentum, * Benicke, Ztschr. f. Geburtsh. u. Gynaek., Bd. ii, Heft 2, 1878, p. 250. •f ScHROEDER, Lohrbuch, Ote Aufl., p. 500. 538 THE PATHOLOGY OF LABOR. portions of the urinary bladder, and sometimes blood, Avitli various products of peritoneal inflammation. The location of the hernia is usually in the posterior vaginal wall, although it may insinuate itself between the uterus and the bladder, and, descending, produce hernia of the labia majora. Perineal hernias are formed by hernial sacs which pass behind the ligamentum latum and distend the jaerinaeum. The intestinal vaginal hernia is the most important variety, inasmuch as it may not only obstruct labor, but may itself become incarcerated or strangulated, thus leading to symptoms of the gravest import. The diagnosis, which can be rendered very probable by palpation per vaginam, is made certain by a rectal examination. Vaginal neoplasmata, the most important of which are carcinomata and fibromata, are rare sources of vaginal stenosis, as is likewise thrombus of the vagina. Slight obstruction to labor may result from a pathological condition of the vaginal mucous membrane described by Winckel,* under the title colpohyperplasia cystica, and consisting of the development in the mucous membrane of numerous small and closely aggregated flattened cysts. The cysts are believed to be pro- duced by the distention of glandular depressions in the mucous membrane with mucus, which, according to Zweifel,f eventually pro- duces trimethylamine gas by decomposition. Others consider the loca- tion of the gas to be in the interstices of the submucous connective tissue. J Vaginismus is rarely a cause of vaginal stenosis in labor, inas- much as it is itself a cause of sterility. It has, however, been found in certain instances to constitute so serious an obstacle to delivery as to necessitate operative interference. In a recent instance in my own practice the spasmodic contraction of an unusually developed levator- ani muscle — -a spasm which was uncontrolled by complete chloroform anassthesia — rendered forceps necessary. After prolonged effort extrac- tion was accomplished, but the head was enormously elongated. The child died of tetanus a few days after birth. In double vagina tlie septum is sometimes a source of slight vaginal atresia. Intrapelvic echinococci constitute a rare cause of vaginal constric- tion. Wiener * collected seven cases of pelvic echinococci, most of which occupied the loose connective tissue between the vagina and rectum. The leading symptoms due to their presence during preg- nancy were deep-seated traction in the pelvis, severe pain, vesical tenesmus, dysuria, and constipation. Menstruation was undisturbetL The tumors were, with one exception, so large as to completely ob- struct the vaginal canal, rendering operative interference necessary- * Winckel, Arch. f.

ABNORMALITIES OF THE SEXUAL ORGANS. 539 In one instance the contraction, from cicatrization of the hydatid cyst following puncture, was so extensive as to produce vaginal stenosis. Hydatids may be mistaken for exostoses of the bony pelvis, for ha3ma- tocele, malignant intrapelvic tumors, pelvic abscesses, or cellulitis. Their differential diagnosis is based uj)on the presence in the pelvis of smooth, tense tumors not connected with the uterus, the gradual development of the tumors without constitutional sym2)toms of any gravity, the presence of similar tumors in other organs, particularly in the liver, the hydatid thrill, which is not often observed on account of the strong pressure to which the cysts are exposed, and, finally, upon the examination of the cystic fluid. III. Uterine Atresia. — Uterine atresias, which occur less frequently than those of any other portion of the genital passages,* may be con- genital or accidental, partial or complete. Complete atresias, observed in parturition, have become so during pregnancy, since conception would not otherwise have occurred. Conglutinatio orificii externi, or adhesion of the lips of the os ex- ternum, is occasioned by the superficial union of the opposing mu- cous surfaces through the medium of inspissated epithelium or of new connective tissue resulting from adhesive inflammation produced by vaginitis or cervical endometritis. Schroeder f regards these atresias as always incomplete, and seeks their origin in the gradual indu- ration of tissues immediately surrounding the os, resulting from old inflammatory processes. According to his views, this pathological con- dition consists of deficient expansibility and not of real contraction of the OS externum. On examination no marked induration of the cervix is felt. The os externum is hardly perceptible to the touch, and can often only be discovered by inspection. If the examination be made during the first stage of labor the internal os is found widely dilated, while the os externum remains persistently contracted and conveys a sensation to the palpating finger akin to that produced by a narrow and tense rubber band. If the finger or an appropriate in- strument be firmly pressed against the os during the pain, it slowly yields and is gradully retracted by the longitudinal cervical contrac- tions. In default of such simple interference the cervical tissues above the os externum become enormously distended, and may finally be ruptured. Zweifel I refers this peculiarly unequal dilatation of the cervical canal to an abnormal presentation of the fetal cranium and to a consequent local expansion of the anterior uterine wall. The OS externum having been simultaneously forced backward into the hollow of the sacrum, the yielding anterior uterine wall then forms a diverticulum which contains the presenting fetal part, and no dilating * Jenks, op. cif., p. 5. f Schroeder. Lehrbnch, 6te Aufl., p. 487. X Zweifel, Arch. f. Gynaek., Bd. v, 1878, p. 149. 540 THE PATHOLOGY OF LABOR. force is exerted upon the external os. Benicke* was unable to dis- cover in his cases the posterior deviation of the os which is assumed by Zweifel as the basis of his hypothesis. Cicatricial atresia of the os externum is rarer than the adhesive stenosis just described. It is usually confined to the lips of the ex- ternal OS, but may involve the cervical canal for a varying distance. Its most frequent causes are post-partum ulceration, inflammation, cauterization of the cervix, and mechanical irritation applied for the purpose of producing abortion. The diminution of the uterine dis- charges during pregnancy affords a favorable ojiportunity for the de- velopment of the stenosis under consideration. If cicatricial atresia exist, the os externum remains undilated in labor, the cervix becomes immensely distended, and may even rupture, unless the os be dilated by artificial means. The diagnosis rests upon the discovery, usually easily made, of the cicatrized os externum. Should the latter have retreated into the hollow of the sacrum, the diagnosis may only be accomplished with difficulty, or the expanded cervical tissues be mis- taken for the fetal membranes. This error is avoided by the discovery of the direct continuity of the vaginal wall and the supposed mem- branes, and by inspection through a proper speculum. Abnormal rigidity of the os externum is often encountered in mul tiparae as the result of genuine cicatricial processes or of fibrous hy- pertrophy. This condition is especially observed in connection Avith prolapse of the uterus. A similar rigidity in aged primiparse is due to atrophic degenerative changes in the cervical tissues, or to hyper- trophy of the portio vaginalis, f I have met in my own practice witli an instance of atresia of the os internum and of the adjacent structures, the result of cicatrices from a former labor. At the time I first saw her the patient had been several days in labor, and the waters had escaped ; she had a temperature of 102°, and was delirious from pain and exhaustion. While preparing to perform the Caesarean section, rupture of the uterus suddenly oc- curred, and the patient died in a few hours. Haemorrhages occurring into the hypertrophied cervical tissue are distinguished as cervical thrombi, and constitute obstacles to delivery. The retraction and dilatation of the cervix may, further, be obstructed by adhesions in the lower segment of the uterus between the decidua and the chorion. Acute elongation of the anterior lip of the os externum, in conse quence of its incarceration between the foetus and the bony pelvis, and of the resulting cedema of its tissues, is referred to by Ilirte I as a rare but serious obstacle to delivery. Parturition is sometimes delayed by double uterus. The obstruc- * Benicke, op. cif., p. 252. f Benicke. op. ciL, p. 240. X HiBTE, Arch. f. Gynaek.. Bd vii, 1875, p. 552.

The uterine atresias produced by carcinomata, fibromata, and ova- rian tumors are considered in another chapter. Symptoms of Atresias of the Genital Canal. — The principal symp- toms of atresia in the unimpregnated state relate to the jjartial or complete retention of the menstrual fluids. If the stenosis be com- plete the uterus is enlarged and fluctuating, while severe uterine pains attend each monthly period. J The Fallopian tubes are dilated. Some of the retained and decomposed menstrual fluid may be forced through the tubes into the peritoneal cavity, producing serious or fatal joerito- nitis. The mere dilatation of the uterus may become so excessive as to produce peritonitis.* Septic poisoning is sometimes induced by absorption of putrescent materials from the uterine cavity. A symp- tom often serving to attract attention to the existence of abnormal vaginal contraction is inability to perform the sexual act. The most prominent symptom of atresia during parturition con- sists, in general terms, of mechanical obstruction to delivery, which is more or less serious in proportion to the degree of existing stenosis. The special symptomatology of the individual pathological conditions productive of atresia has been considered in connection with their respective anatomical characters. Note. — Atresias for the most part require to be treated each by itself, according to the principles of surgical art,. In p. paper by Professor 1. E. Taylor, in the fourth volume of the Transactions of the American Gynascological Society, entitled Atresia of the Vagina. Congential or Accidental, in the Pregnant or Non-pregnant Female, the author relates a case of seemingly complete imperforation of the vagina complicating labor, where he succeeded, by scraping with the finger-nail during the pains, in passing the index-finger through the intervening membrane to the child's head, and eventually in securing an opening large enough for the birth to be ac- complished. I had previously reported two similar cases, one in the New York Medical Journal, and one to the Obstetrical Society. || The first, where I was aided by Professor Fordyce Barker, occurred in Bellevue Hospital, and the second in private practice. In both, similar success followed a gradual dissection of the A'aginal walls with the finger. In such cases usually a depression, or a thinned point in the tissues, indicates the direction to be followed. C. Braun states, how- ever, that he has seen three cases where vesico-vaginal fistulns were produced by this tunneling process, an admonition to extreme caution in its performance.^ For stenoses of the vagina, dilatation should be employed, either by means of compressed * MuLLER, Arcli. f.

In Pregnancy.— Becmse of the disposi- tion of uterine myomata to produce sterility, they naturally constitute comparatively infrequent complications of pregnancy. They are sub- divided, according to their location, into subperitoneal, interstitial, and submucous myomata. The presence of either variety diminishes the probability of conception, but none absolutely precludes the possi- bility of its occurrence. In most instances, myomata produce no symptoms during pregnancy, and do not disturb labor. Subperitoneal myomata prevent conception and interrupt utero- gestation only when they attain large dimensions, and their prejudicial influence is then usually referable to the uterine retroversions or retro- flexions which they induce. Interstitial myomata are more likely than the preceding variety to occasion abortion or premature delivery, either by producing uterine flexions, or by acting as the exciting cause of haemorrhages, which are more severe when the placenta is located over the site of the tumor. This statement applies particularly to post- partum haemorrhages, inasmuch as the muscular atrophy induced by the moyma prevents the ready and complete closure of the uterine sinuses. Submucous myomata rarely permit of conception, which, in the event of its occurrence, is almost uniformly followed by abortion, due usually to metrorrhagia. In cervical myomata, however, pregnancy may progress to its normal termination. Myomata ordinarily partici- pate in the uterine hypertrophy of pregnancy, becoming at the same time softer and more succulent. This change in consistence, which is referred to increased vascularity, to colloid transformation, and to serous infiltration, is attended by dilatation of the lymphatics, Avhich may lead to the formation of cysts. The softened tumor readily undergoes changes of form under the influence of increasing intrapelvic pressure and of uterine traction. It may become so flattened that it ceases to be recognizable as a tumor, but regains its earlier shape after delivery. The diagnosis of uterine myomata, particularly of the interstitial and submucous varieties, is often attended during pregnancy by diffi- culty, inasmuch as their symptoms and signs are obscured by those of pregnancy. On the other hand, the existence of myomata may pre- vent the recognition of pregnancy. Fibrous tumors may be mistaken for fetal organs or for intra-uterine cystic tumors. Careful palpation by the combined method with two fingers in the vagina, or the half or entire hand in the rectum if necessary, should be employed to make out the shape, position, and consistency of the suspected growth. As ABNORMALITIES OP THE SEXUAL ORGANS. '543 a further aid to diagnosis, Landau recommends puncture through the vagina, by means of which the presence or absence of fluid and the density of the tissues penetrated can be determined. 2. In Parturition and the Puerperal State. — Uterine polypi act as impediments to deKvery only when they are situated beside or in front of the advancing child, and are possessed of considerable size and con- sistence. If the tumor be small, movable, and yielding, it may occa- sion trifling obstruction to parturition, and may even be exj)elled by the advancing foetus, after rupture of its pedicle. Interstitial myomata, when corporeal, constitute impediments to de- livery only when located in the lower segments of the uterus. Even when thus situated, they often spontaneously recede from the pelvic cavity under the influence of the longitudinal uterine contractions. By exerting traction on the uterine parietes they aggravate the sever- ity of the pains, and sometimes produce rupture of the uterine wall, in which their growth has already determined atrophic degeneration. By interfering with symmetrical uterine contraction, interstitial myomata render the pains irregular and inefficient, besides predisposing to ante- and particularly to post-partum haemorrhage. By altering the form of the uterine cavity and preventing the engagement of the head in the superior strait, this variety of myoma frequently produces abnormal positions and presentations. In a case of my own eclampsia resulted apparently from the same set of causes as those which obtain in multi- ple pregnancy. They also predispose to the development of retro- flexions in the puerperal state. When interstitial myomata are de- veloped in the cervical tissues they almost invariably offer a mechanical impediment to delivery, and are rarely capable of being displaced above the superior strait. If, however, they have become intravaginal and their base be not too extensive, they are often readily amenable to ap- propriate surgical interference. In default of the latter, fatal com- pression may be exerted upon the fetal cranium, or the vesico-vaginal septum may be lacerated during labor. Subserous myomata are ordinarily developed in the posterior uter- ine wall. If connected with the body of the uterus and located above the retro-uterine reflexion of the peritonaeum, they may be spontane- ously extruded from the pelvic into the peritoneal cavity. They origi- nate, however, most frequently in the cervical tissues, and, extending downward, become retrovaginal, more or less completely occupy the pelvic cavity, and offer, provided their size be at all considerable, an insurmountable obstacle to parturition. This variety has been desig- nated as the incarcerated uterine myoma. The prognosis is grave, a fatal termination having been noted in one half of the mothers and in two thirds of the children. Treatment.— Myomata in most cases, it should be remembered, pro- duce no symj)toms during i)regnancy, and do not disturb labor. If 544 THE PATHOLOGY OF LABOR. of small size, they may escape observation altogether. Their mere presence, therefore, does not indicate ground for interference. As a rule, it is well to observe a waiting policy until the need of assistance becomes evident. The induction of abortion where the tumor threatens to disturb the later progress of pregnancy is a questionable expedient on account of the tendency to profuse haemorrhage, and the difficulty of removing the secundines. Dr. A. Kessler reported a case, which I saw with him in consultation, where, after the expulsion of a four months' fcetus, it was found impossible to reach the placenta. The latter occupied an inaccessible position near the right cornu, far out of reach of the hand, while the convexity of the tumor was so great as to interfere with the working of ovum forceps or the curette. The patient died of septi- c£emia. Kemoval of the uterus would possibly have saved her life. Kaltenbach has reported a case where he performed the supravagi- nal ampvitation of the uterus between the fourth and fifth months of pregnancy, on account of myomata, the largest of wliieh weighed seven pounds. They gave rise to unendurable pressure and to exhausting hsemorrhages. The patient recovered. T. Landau * has collected eighteen cases in wliich amputation of the pregnant uterus has been performed, owing to disturbances pro- duced by myomata. Of these, eleven recovered and seven ended fatally. If the myomata are pedicled or subserous and of moderate size, their removal during pregnancy by enucleation is justifiable if they threaten complications. The prognosis is not unfavorable, for though in seven- teen operations collected by Landau four patients died, one of these had a large, broad-based multiple tumor, one suffered from nephritis, and two occurred in the days of defective asepsis, hi two of the fatal cases, and in four where recovery took place, abortion followed. If myomata encroach upon or occupy the pelvic cavity, an attempt should be made to raise them above the brim by sustained rectal or vaginal pressure. The most serious obstruction to the birth of the child is offered by cervical and subserous myomata which encroach upon the pelvic space. They are of rare occurrence. The treatment varies according to the intra or extravaginal situation of the growth. In both instances, where the child is living, operative interference should be postponed if possible to end of pregnancy. In the intravaginal form, room should be made for the exit of the child by splitting the capsule and enucleating the myoma. Bleeding from vessels should be controlled by compression forceps, and the cavity should be filled, after the expulsion of the child, with iodoform gauze. Even tumors of large size may be enucleated per vaginam if * T. Landau, Zur Behandlnng derdurch Mrome Complicirten Schwangersehaft und (xeburt. Klin. Vortrage, Neue Folge, No. 2G. ABNORMALITIES OF THE SEXUAL OEGANS. 545 they are first segmented {^^ mo7'cellement^'' of Pean), and are then re- moved piecemeal. Dr. P. F. Munde * has reported a case of pregnancy advanced to the sixth month where an interstitial myoma of the anterior wall of the nterus and of the cervix filled the pelvic cavity almost to the vaginal orifice. After careful deliberation, Munde decided to remove the tumor by enucleation. This he accomplished successfully ; the tumor weighed three pounds. The foetus and placenta were then easily extracted. The mother made a good recovery. Similar successes have been reported by Schroeder, Grimsdale Danyon, and Braxton Hicks. Depaul enuc- leated the morbid growth in the case of fibrous polypus, with a broad attachment (six to seven centimetres) to the cervix. The patient died two months later, but the tumor gave forth an extremely oifensive odor at the time of the operation. With small tumors it may be possible to extract the child first with forceps or version, or after craniotomy, Chambazian reports twenty forceps cases, in which twelve mothers and seven children were saved. Of twenty version cases, only eight mothers and three children sur- vived. But even then it is usually prudent to remove the tumor im- mediately after the birth of the child, owing to the danger of septic infection incident to the bruising of the tissues. Then, on checking the h?emorrhage, the cavity should be filled with iodoform gauze. Polypoid growths should be pushed back into the uterus, if pos- sible, in cases where the pedicle is out of reach. When, however, the tumor is shoved down in advance of the head, and the pedicle is ac- cessible, it should be removed with the ecraseur or with scissors. Chambazian f reports eight cases of extirpation performed during jDreg- nancy, on account of haemorrhage, with one death, due not, however to the operation, but to eclampsia. In eight cases of removal during labor there was no death. In pelvic obstruction due to extravaginal myomata the growth is usually of cervical origin. As a rule, it develops in the pelvic con- nective tissue behind the uterus, and is only roofed over by the peri- tonaeum. As the Caesarean section or the Porro operation is indicated in these cases of impaction, it is desirable, unless the symptoms due to pressure are urgent, that interference should be postponed to the end of pregnancy. Sanger J collected forty-three cases of Cfesarean section complicated by myomata. Of these, in thirty operations performed previous to 1874 but two recoveries were reported. Since 1874 there have been thirteen operations, with five recoveries. Of these, in three cases — viz., in Tar- nier's, Zweifel's, and Agnew's — the Porro method was followed, and all * Munde, Am.

Of the ten cases in which the older method was adopted, in five— viz., in those of Cazin, Cornelins Olcott, Martin, San- ger, and Moses Baker — the patients recovered. In four of the five fatal cases, the particulars are furnished in four. In that of Netzel, the membranes ruptured three days before the operation ; in McCormack's, the patient had been fifteen days in labor, and general peritonitis exist- ed ; in T. G. Thomas's, the membranes had ruptured, and, previous to operating, unsuccessful attempts at delivery had been made by means of version, craniotomy, and embryotomy ; in Spiegelberg's, no contrac- tion followed the section, and the patient died from exhaustion due to hasmorrhage. Since the appearance of Sanger's memorable work, of seven cases where his method was employed in consequence of myomata, only that of Leopold recovered. In the cases which terminated fatally the patients were, however, all in a septic condition at the time of the opera- tion. Still, owing to the excessive vascularity, the imperfect contrac- tility, and the hindrances to drainage in myomatous uteri, the condi- tions at present favor a resort to the Porro method. Successes have been reported by Schroeder, Hofmeier, von Ott, and L. Landau., in cases where the extraction of the child was followed by the removal of the uterus. In each the intro-abdominal method was employed in the treatment of the stump. Landau's case was especially instructive. Tlie abdominal incision extended from the symphysis to a hand-breadth above the navel. The uterus was turned out, and after tlie adjustment of a rubber ligature the child was removed alive by the uterine incision. In bringing the uterus forward the retro-uterine and retro-cervical tumor was dragged out of the pelvic cellular tissue in which it was imbedded. The elastic ligature was placed below the entire uterus, the ovaries, and the tumor, the uterus was severed, and the tumor was enucleated. The raw surfaces of the stump were first united by eight deep sutures, which likewise included the bed of the tumor, and then the peritonaeum was drawn from the sides to cover the wound. In this case it was thought best to em- ploy drainage through Douglas's cul-de-sac by means of iodoform gauze, owing to the enormous serous transudation of the tissues. The gauze was changed at the end of forty-eight hours, and on the fourth and sixth days. On the seventh day the wound was allowed to heal. The patient left the liospital after three and a half weeks. The child weighed seven pounds at its birth, and throve afterward. (Klinische Vortrage, N. F.,Ko. 26.) Ott, after removing uterus and ovaries, left the retro-uterine tumor in situ. The wound was closed by a triple-stage suture. As a consequence of the re- moval of the ovaries, the myoma rapidly shrank to small dimensions. (Arch, f. Gynaek., Bd. xxxvii, p. 88.) II. Carcinoma of the Cervix Uteri.— 1. In Pregnancy. — Uterine cancer, which is one of the gravest comj^lications of pregnancy, is, if primary, almost without exception of ' cervical origin. Conception often occurs in the earlier stages of the disease, and since it is only ABNORMALITIES OP THE SEXUAL ORGANS. 547 absolutely prevented by a carcinoma which completely occludes the cervical canal, it occasionally takes place even in the later stages of the neoplasm's growth. The existence of j^regnancy usually hastens the development of the cancer, the more rapid growth of which is probably referable to the increased vascularity of the uterus and to the correspondingly augmented activity of its nutritive processes. In rare instances the occurrence of pregnancy seems to arrest the devel- opment of the local and general symptoms referable to the cancerous growth. In the majority of cases the neoplasm does not interfere with the completion of normal utero-gestation, although abortion or premature delivery is a frequent result of its development. These issues of pregnancy are most frequently determined by cancerous tu- mors whose progress has invaded the higherj supravaginal portions of the cervix, and is probably occasioned by the interference, on the part of the neoplasm, with the normal process of uterine growth and expansion. The traction exerted by the enlarging cervix upon the unyielding tissues of the tumor may also produce a solution of their continuity, and give rise to formidable haemorrhage. In very excep- tional cases uterine carcinoma seems to protract the period of gestation far beyond its normal limits, in which case the foetus dies and under- goes the changes usual in retention. 2. 1)1 Parturition and the Piierperal State. — If the cancer be con- fined to the lower margin of the cervical canal, the expansion of the latter is not materially interfered with, and delivery may be safely and speedily accomplished. If, however, the morbid process has involved the entire portio vaginalis, or has even extended quite to the os inter- num, the inelastic tissue of the cancerous growth has replaced the ex- pansile muscular fibers, and an opening of sufficient caliber for the passage of the foetus can only be produced by rupture and contusion of the degenerated and unyielding cervix. The immediate result of such a laceration is violent haemorrhage, which is, however, quite amenable to treatment. The consequence of the excessive pressure to which the cervix is subjected during labor is necrosis of the con- tused tissues, which is frequently followed by fatal sejiticaemia. The diagnosis is accomplished by the same means which are em- ployed in the detection of cervical cancer in the unimpregnated con- dition. The prognosis is doubtful for both mother and child. The latter is imperiled by its liability to premature expulsion, and by the me- clianical obstruction to its birth produced by the tumor. The moth- er's life is not only shortened by the rapidity of the cancerous growth usually induced by pregnancy, but is jeopardized by her increased lia- bility to abortion, post-partum haemorrhage, and puerperal fever. Treatment. — During pregnancy, in cases where the disease is con- fined to the cervical portion, either amputation or excision should be 548 THE PATHOLOGY OF LABOR. performed. The time selected for operation is usually the fourth month. Abortion does not necessarily follow. In advanced stages, where the carcinomatous process has invaded the contiguous tissues, operative interference should be postponed until the end of gestation. Just in proportion as the outlook for the mother grows questionable, the interests of the child rise in importance. An extensive removal of diseased tissue during pregnancy exposes the mother to the imme- diate dangers of j)remature labor and subsequent septicaemia. Upon the advent of labor, if the child be living, and the upper vaginal tis- sues are largely involved, the Caesarean section or the Porro operation certainly holds out the hope of saving one life, and probably does not greatly increase the peril to which the other is exposed.* Dr. Fordyce Barker stated that he met with three cases of spontaneous delivery where the cervix was carcinomatous, in all of which the mother sur- vived the childbed period. Such good fortune, however, is necessarily rare, and is only likely to result in j^atients whose tissues are but mod- erately affected. Frommel f reports a case from the Berlin Clinic where, the child being dead, Schroeder broke away with his hands large masses of the neoplasm, and thus provided a passage of sufficient size to permit the extraction of the child by version. The patient was discharged on the tenth day, but died a few days after. Alfred Gon- ner | recommends that labor be allowed to proceed until dangerous symptoms call for active measures, or the limit of physiological dilata- tion is reached. Then, if the vagina is not too extensively implicated, by means of incisions and the partial extirpation of the diseased mass with the galvano-caustic wire, the thermo-cautery, and volsella forceps, room should be made for the extraction of the child by forceps, or after^ version. Of four cases thus treated, the mothers all recovered from the immediate effects of the operation, and three of the children were born living. III. Ovarian Tumors. — 1. In Pregnancy. — Ovarian tumors, par- ticularly those of the cystic variety, are quite often encountered as complications of pregnancy. They usually antedate conception, but may make their aj^pearance during pregnancy. Utero-gestation often favors their development by increasing the general vascularity of the pelvic viscera, although an arrest of growth and an actual retrogress- ive metamorphosis of the tumor seem to be the occasional effect of * Herman (Trans, of the Obstet. Soc, of London, vol. xx, p. 191) reports twelve Caesarean operations, with four recoveries. In a case reported by the author in 1887, the patient lived two months after the Caesarean section, and then succumbed to the ravages of the cancerous affection. The child has thriven up to date — 1881. lieopold has performed the Porro operation twice for carcinoma with success, f Frommel, Zur operat. Therapie d. Cervix-Carcinoms in d.

I ABNORMALITIES OF THE SEXUAL ORGANS. 549 intercurrent conception.* This retrogressive process affects only cys- tic tumors, and may result from the uterine pressure, which facilitates the absorption of their contents. After delivery the cysts present on palpation a relaxed and flabby condition. The natural tension of the tumor is soon restored by the secretion of additional fluid, except in those rare cases in which the compression of the gravid uterus seems to initiate a permanent process of retrogression and absorption. Wernich f advanced the opinion that the assumption by benign ovarian tumors of a malignant character is determined by the occur- rence of pregnancy, and Spiegelberg J regards this transition as posi- tively established. The ovarian tumors under consideration may be bilateral. If they be of moderate dimensions, they may not interfere with utero-gestation or delivery, except by a slight aggravation of the usual disturbances attendant upon pregnancy. An ovarian tumor is, however, liable to occasion abortion or premature delivery if it be con- fined by adhesions to the pelvic cavity, or be closely connected to the uterus. Under these circumstances, abortion results from interference on the part of the new growth with the natural uterine expansion, or from the retroflexion which it induces. In rare instances a rotation of the cyst upon its axis, followed by strangulation of its pedicle, is observed. This deplorable accident leads to a lethal issue by shock, by gangrene of the cyst and consequent sejDticsemia, or by heemorrhage into the tumor and the peritoneal cavity, followed by peritonitis. The rationale of the morbid phenomena referable to tumors of larger size is entirely different. These tumors do not often occasion abortion or premature delivery, but gravely complicate the later periods of preg- nancy by means of the pressure which they, in common with the gravid uterus, exert upon the abdominal and thoracic viscera. Ascites and dyspnoea are the chief results of the augmented intra-abdominal ten- sion. (Edema of the lower extremities is often observed. The ova- rian cyst sometimes ruptures and produces fatal collapse, peritonitis, or septicemia. The escaped cystic fluid may, however, be absorbed, and pregnancy reach a natural termination. Diagnosis. — If the ovarian tumor be of small size, it may be com- pletely masked by the growing uterus, or may be mistaken for a por- tion of the latter. If, on the other hand, the surface of the tumor be irregular and nodular, the uterus may, at an early period of pregnancy, itself be regarded as a part of the cyst. Palpation and auscultation will, however, usually afford satisfactory diagnostic points of differen- tiation. Especially the softness of the pregnant uterus contrasts with the tense condition of an ovarian cyst. Moreover, the absence of the menses in patients with an ovarian tumor, and an unusually rapid in- * ScHROEDER, Lehrbuch, p. 309. f Wernich, Beitr. z. Oeburtsh. u. Gyn., Bd. ii, p. 143, X Spiegelberg, Lehrbuch, p. 297. 550 THE PATHOLOGY OF LABOR. crease iu the dimensions of the abdomen, shonld awaken the suspicion of combined pregnancy and ovarian tumor. 3. In Parturition and the Ptmyeral State.— The dangers result- ing in parturition and the puerperal state from ovarian tumors com- plicating pregnancy are twofold, and consist (a) in the obstruction to labor which they occasion and (b) in the results of the morbid pro- cesses determined in the neoplasms themselves by the excessive press- ure of the surrounding tissues. (a) If the ovarian tumor is confined within the true pelvis in such a way as to render its spontaneous or manual displacement impossible, it may offer a most serious impediment to the expulsion of the fa3tus. Dermoid cysts manifest a more decided tendency to contract adhesions in the pelvis than other ovarian tumors, and afford on this account, as well as because of the greater consistence of their contents, a worse prognosis than any other variety.* Obstructed labor more frequently results from the presence of small than from that of large ovarian tu- mors, since the latter oftener escape into the abdominal cavity during pregnancy, and are unable at any subsequent period to effect an en- trance into the true pelvis. (b) Even if the obstacle offered to parturition by an ovarian tu- mor be trivial, the changes induced in its own substance by the par- turient act may be productive of very serious results. The pressure and traction exerted upon the pedicle of the cyst are often so severe as to produce its strangulation, followed by necrosis of the tumor, with consequent septic poisoning. Rupture of the sac, with its fatal consequences, may also occur, or such severe contusions of the tumor may be occasioned by excessive pressure as to result in gangrene of its entire mass. The development of the foetus is, as a rule, not inter- fered with by ovarian tumors. The latter manifest a tendency to very rapid development in the puerperal state, except in those rare cases characterized by permanent retrogressive metamorphosis and absorp- tion. Ovarian tumors are a dangerous complication of pregnancy and labor. Jetter collected 215 cases with 04 deaths. Fortunately, how- ever, the results of ovariotomy are as favorable in the pregnant as in the non-pregnant state. The operation does not necessarily interfere with the continuance of gestation. So soon as the existence of an ova- rian tumor is recognized, therefore, in a pregnant woman, its imme- diate removal is indicated, f When the time is a matter of election the * SCHROEDER, op. cif., p. 501 . t Olshausex (Krankheiten der Ovarien) 188G. collected 82 operations performed by 44 operators. There were eight deaths, four of which took place before the days of antisepsis. Olshausen operated fourteen times. Four of the mothers aborted and two died. Schroeder {Vide Straty, Ztschr. fiir Geb. und Gynaek., vol. xii. p. 268) operated fourteen times. All the mothers recovered. Twelve of the children (including twins) went to terra. Spencer Wells operated ten times. Nine women ABNORMALITIES OB^ THE FCETUS. 551 operation should be performed early in pregnancy. In the later months the conditions are less favorable, owing to the excessive vascu- larity of the pelvic organs and the consequent development of the ves- sels in the pedicle. Pippingskold, however, operated successfully ujion a woman seven hours before the birth of a full-term child. The alternative of ovariotomy consists in abiding the end of preg- nancy, and then, when the tumor interferes with the birth of the child, in pushing it uj)ward above the pelvis or, failing after repeated effort, in puncture of the cyst. The cul-de-sac of the vagina affords generally the most convenient point for the introduction of the trocar. The best time for tapping is during the existence of a pain, when the cyst is rendered tense by pressure. CHAPTER XXIX. ABNORMALITIES OF THE FCETUS WHICH OFFER AN OBSTRUC- TION TO DELIVERY. Premature ossification of the cranium. — Hydrocephalus. — Encephalocele. — Hydro- thorax. — Ascites. — Other causes of abdominal distention. — Tumors of the trunk. — Monstrosities. — Double monsters. — Acardiaci. — Anoncephalous monsters. — Abnormal positions. — Spontaneous version. — Spontaneous evolution. I. Fetal Diseases which obstruct the Expulsion of the Head. Premature Ossification of the Fetal Cranium. — This condition is characterized by the complete or nearly complete closure of the fonta- nelles. The head, therefore, loses its compressibility, and no longer undergoes those changes of form which constitute so imjjortant a part in the mechanical processes of delivery. As the anomaly is apt to in- terfere with brain development in infancy, the late Dr. John E. Blake * advocated early jaerforation where the interests of the mother had to be consulted. As I have never met with this form of dystocia in a large number of instrumental deliveries, I can not but regard it as extremely uncommon. Hydrocephalus. — Congenital hydrocephalus of sufficiently marked development to constitute an impediment to parturition is compara- tively rare, occurring, according to the statistics of Madame La Cha- pelle,f only fifteen times in 43,545 deliveries. It consists usually in a serous effusion confined to the cerebral ventricles. The effusion may, recovered and went to terra. A. Martin reports three ovariotomies. The mothers recovered. Pregnancy was not interrupted. * Blake, Am.

Etiology.— The etiological factors of the disease have not been as- certained, although Herrgott f assumes an invariable causative relation between coexisting cretinism and hydrocephalus. Morbid Anatomy. — The accumulated serum compresses the cerebral parenchyma and produces dilatation of the cranial cavity, which may become excessive. The cranial bones become abnormally thin, being in some instances no thicker than parchment. Their continuity may be interrupted by apertures of varying size, through which the con- tents of the cranium may protrude, constituting an encephalocele. The skull is of disproportionate magnitude as compared with the face. The head may attain the dimensions of that of an adult. The fore- head is prominent and bulging, the sutures are widely open, and the fontanelles of large diameter. The body of the foetus is usually well developed, and of a size corresponding to the existing period of preg- nancy, although spina bifida and other malformations may coexist. Hydramnion frequently complicates hydrocephalus. Diagnosis. — Cystic tumors, spina bifida, encephalocele, and the skull of a macerated foetus, are most frequently mistaken for hydro- cephalus. The differential diagnosis is based upon different signs, ac- cording to the position and presentation of the foetus. If the head present and be still above the superior strait, abdominal palpation may sometimes detect a large, rounded, and hard tumor above the pubes, , while auscultation discovers the maximum intensity of the fetal cardiac sounds above the umbilicus. The abdomen is unusually distended. If the head has descended somewhat into the pelvic cavity, palpation per vaginam reveals a fluctuating sac, which becomes notably tense during the jiains. In the interval between the uterine contractions, the broad fontanelles, the thin bones, and the wide sutures are readily felt. These signs may, however, fail if the cranial bones be thick and the sutures already ossified. In this case the disproportion between the forehead and face, the bulging frontal bone, and the prominence of the superciliary ridges are important aids to a diagnosis. If tlie mem- branes be ruptured, the hairy scalp may be felt. The diagnosis is easier when the cranial cavity is not greatly distended. In case of a breech presentation, the diagnosis, which is then more difficult, must chiefly rest upon the detection, at the fundus, of a tumor larger than the nor- mal fetal cranium. The previous occurrence of hydrocephalus in the same subject and feeble fetal movements may, in this instance, slightly facilitate the task of the diagnostician. * Nouv. diet, de med. et chir.prat., vol. xiii, article Eneophale, p. 151. t Herrgott, Des mal foetal, q. peuvent faire obstacle a raccouch., Paris, 1878, p. 13. ABNORMALITIES OP THE FCETUS. 553 Mechanism of Delivery. — The course of parturition is sometimes not materially impeded even by a largely developed hydrocephalic foe- tus. This may be due, if the bones be attenuated, to the ready mold- ing of the fetal cranium to the pelvis, or to rupture of the head and escape of the serum, which event occurs chiefly in breech presentations. The presentation materially affects the course of delivery. If the head be forced with its greatest circumference against the superior strait, it adapts itself less readily to the pelvis than when it impinges later- ally or obliquely on the pelvic entrance. The difficulties of delivery are increased if the cranial bones be firm and thick, or the sutures ossified. Breech presentations are favorable to a speedy delivery, in that the head is subjected during its descent to more equable pressure by the pelvic parietes, and therefore assumes a conical shape best adapted to insure its easy expulsion. Spontaneous delivery is, however, rare. In the vast majority of cases operative interference becomes necessary. Prognosis. — The child's life is usually sacrificed if the anomaly be sufficiently marked to considerably protract parturition. Even if the child be born alive, it will probably succumb at an early period of ex- tra-uterine life. The prognosis with reference to the mother depends largely upon the time at which obstetrical aid is extended, and upon the nature of the remedial measures adopted. If the labor be too long protracted, vesico- vaginal fistula may result from pressure of the fetal head, or the mother may die from exhaustion or from rupture of the uterus. Eupture of the uterus is comparatively frequent, having oc- curred in sixteen out of seventy-four cases of hydrocephalus collected by Thomas Keith. The laceration usually occurs in the vicinity of the cervix, but is often located at the fundus uteri. The treatment consists in puncturing the head with a fine trocar and allowing the fluid to escape. If practicable, the child should be subsequently turned and extracted by the feet. The forceps is useless, as it can not be made to take a firm hold. If version is found to be attended with dif- ficulty, the opening should be enlarged, and the head extracted with the cranioclast. If the child is extracted by the breech without pre- vious perforation ^of the head, in cases of difficulty, Tarnier recom- mends section of the vertebral column and the withdrawal of the cra- nial fluid by means of an elastic catheter passed to the brain through the spinal canal. Congenital Encephalocele. — This abnormality of the fetal cranium consists in the accumulation beneath the scalp of cephalic fluid, with or without an investment of meningeal or of cerebral tissue. The sac containing the fluid is attached to the cranium by a pedicle of varying length and form. The aperture through which the fluid originally contained within the cranium finds exit may be produced by attenu- ation of the cranial bones attendant upon hydrocephalus, or may be due to arrested development. In some instances the encephalocele is gg^ TUE PATHOLOGY OF LABOR. found still communicating with the cranial cavity through its pedicle, but in others the latter is impervious. Encephaloceles vary in size from hardly perceptible sacs to tumors of larger circumference than the cranium itself. They may occupy any part of the periphery of the head, but are most frequent in the frontal and occipital regions.* The head may itself be hydrocephalic or normal. The cause of the anomaly in question is not definitely known, but is inferred to be of inflammatory nature. Encephaloceles rarely obstruct delivery, because, their most fre- quent seat being in the frontal or occipital region, they are expelled either before or after the head. Their presence seems to determine nutritive changes in the cranial bones, whereby the latter, being ren- dered softer and more yielding, are more readily expelled. The amount of obstruction caused by the encephalocele will reach its maximum when the size is large, the pedicle short, and the seat lateral ; but simple puncture usually suffices to evacuate the sac, and obviates further diffi- culty. The prognosis for both mother and child is far better than in cases of congenital hydrocephalus. II. Abnormal Conditions of the Fcetus •which obsteuct the Expulsion of the Trunk. Hydrothorax, unattended by serous effusion into any other of 'le closed cavities of the body, is infrequent, and when present is rardy of sufficient extent to offer any impediment to delivery. Spiegelberg encountered only one such case, and refers to but two others observed by Hohl.f Ascites, although more frequent than hydrothorax, ordinarily con- stitutes an insignificant obstruction to parturition, on account of the yielding character of the abdominal Avails and the small amount of fluid usually present. It has, however, in some instances markedly retarded delivery.;]; Ascites and hydrothorax are more frequently associated than iso- lated, and present, when combined, no inconsiderable obstruction to delivery. Pericardial effusions of varying magnitu(fe may exist simul- taneously with either or both of these affections.* The size of the fetal abdomen may be so much augmented by dis- tention or enlargement of its viscera as to obstruct labor. Among the causes of abdominal distention from this source may be cited : {a) Cystic degeneration of the kidneys ; || (b) dilatation of the uri- * Herrgott, op cit, p. 121. . f Spieoelberg, Lehrbuch, p. 528.

ABNORMALITIES OF THE FCETUS. 555 nary bladder ; * (c) dilatation of the ureters ; f (d) fibro-cystic degen- eration of a testicle still retained in the abdomen ; J (e) enlargement of the liver, due to degenerative processes;* (/) enlargement of the uterus, produced by secretions accumulated in its cavity, the cervix being impermeable ; || (g) enlargement of the pancreas ; ^ (h) enlarge- ment of the spleen ; () (i) one fcetus included within another. In this case one foetus is completely invested by the integument of the other, and is attached to the latter by a pedicle, which is usually inserted either in the sacro-coccygeal, perineal, or cervical regions. I A case of extensive anasarca of the foetus, characterized by the peculiar gelati- nous nature of the fluid contained in the subcutaneous cellular tissue, is reported by Keiller to have produced dystocia. Emphysema of the entire fetal trunk may result from putrefaction occurring in the tissues of a child retained for some time in utero after the escape of the am- niotic fluid. • The putrefactive processes owe their origin to the en- trance of air within the uterus. The gaseous products of decomposi- tion are developed in all the fetal tissues and in the cavities of its body. The skin is distended, translucent, and glistening. It crepitates on pressure, and gas escapes from incisions carried through the cuticle. The trunk and extremities are largely increased in volume, and their augmented size offers an obstacle to delivery which the uterine forces, probably already exhausted by prolonged expulsive efforts, can not overcome. In such cases the bulk of the child should be diminished by punctures of the skin to allow the gases to escape, and when the head presents it should be extracted with the cephalotribe. Tractions upon the extremities are liable to be followed by their separation from the trunk. Tumors developed in different parts of the fetal trunk may disturb parturition. The most frequent site for these tumors is the sacral and perineal regions, where they are developed between the sacrum, the coccyx, and the rectum. Their size varies from that of a small wal- nut to that of the fetal cranium at term, and it may even exceed these dimensions. The tumors may be either cystic, fatty, vascular, carti- laginous, osseous, or carcinomatous. So-called cysto-hygromata are also frequently observed in this situation. Similar neoplasms may be located in the axilla, upon the pectoral muscles, and in the anterior or * Whittaker, Am. Jour, of Obstet., vol. iii, 1871, p. 380; Duncan, Edinburgh Med.

Spina bifida, when accompanied by the formation of a large hydrorachitic sac, constitutes another form of congenital fetal tumor, and is most frequently observed in the lumbo- sacral region. Ectopia of the abdominal viscera, hernias, hydatid cysts, and encysted neoplasms of the abdominal walls sometimes constitute tumors sufficiently extensive to impede parturition. We may also cite anchylosis of the fetal joints, adhesions of the extremities to the trunk or to one another, and rigor mortis, as rare abnormalities which inter- fere with that pliability of the child requisite for its adaptation to the parturient canal, and finally, adhesion of the foetus to the placenta or to the uterine parietes as causes of dystocia.* Diagnosis. — An accurate differential diagnosis between these varied morbid conditions can, as a rule, only be made after delivery. If en- largement of the trunk be present, the head or breech is born without difficulty, but, the progress of parturition being then completely ar- rested, an investigation easily reveals the existence of an abnormally large trunk. A hvdrorachitic sac is liable to be mistaken in a breech presentation for the fetal membranes. Its consistence is, however, not altered by the occurrence of uterine contractions, and no fetal parts are felt beneath the membrane, which is found to be continuous with the fetal cutaneous surface. III. Monstrosities. Dystocia is more frequently produced by double monstrosities than by any other variety. These are divided by Veit f into three principal classes, characterized, respectively, by — 1. Incomplete double forma- tion of the upper or of the lower extremities ; 2. Two separate bodies united either by their upper or by their lower extremities; 3. Two separate bodies attached to each other either by their al)dominal or by their dorsal surfaces. Diagnosis. — The differential diagnosis of the individual deformities is usually impossible in the earlier stages of parturition. Even in the succeeding stages it is difficult, since separate twins may present essen- tially the same phenomena. The diagnostician will derive some assist- ance from the facts that certain women seem predisposed to the devel- opment of double monsters, and that certain smaller and easily recog- nizable deformities of the extremities (as club-foot) are often merely complications cf more important ones, and serve to indicate the exist- ence of the latter. The family history may furnish valuable assistance, inasmuch as the deformities under consideration are sometimes heredi- tary. Double monsters are most frequently observed in multiparae; but this fact is referred by Veit J to the relative numerical preponder- * Whittaker, Am. Jour, of Obstet., vol. iii, 1871, p. 247. f Veit, Volkmann's Samml. klin. Vortr., Volkmann, 1879, Nos. 1G4, 165. + Veit, op. cit., p. 1318. ABNORMALITIES OF THE FCETUS. 557 ance of the former over primiparae. "When parturition has progressed sufficiently to allow of introduction of the hand within the uterus, should the necessities of the case call for this measure, the diagnosis becomes clear. Mechanism of Labor. — The natural forces suffice, according to the statistics of Playfair and Hohl,* for the delivery of double monsters in more than fifty per cent of the cases. This fact may be attributed to the comparatively small dimensions of the foetus and to the frequent occurrence of abortion or of premature delivery in cases of this nature. The course of parturition in a case of the first variety is similar to that obtaining when the head of a single foetus is of unusually large di- mensions. The second variety does not ordinarily seriously interfere with delivery, particularly if there be a breech presentation. In this case the bodies pass through the parturient canal simultaneously, lying parallel to each other. One head then passes along the hollow of the sacrum and is first expelled, while the other is retained above the brim, its neck being bent into close apposition to the pubes until after the exjDulsion of its fellow. Should there, however, be a disparity be- tween the lengths of the necks, both the heads may simultaneously j)ass through the pelvic canal. When they reach the outlet, the head attached to the longer neck is expelled. The second head must then be expelled with the neck and shoulders of the former. Under these circumstances, interference on the part of the obstetrician is usually required. Head presentations are the most common ones in cases of the third variety, and the course of parturition is as follows : The head of one foetus is born, that of the other being detained above the pelvic brim. The trunk belonging to the first head then follows. Xext comes the second trunk ; and, finally, the head belonging to the latter. Spon- taneous delivery, when it occurs, is usually eifected in this manner. Head presentations of the first variety, i. e., those in which a single trunk possesses two heads, usually pursue the course Just described. Prognosis. — The prognosis for the child is very unfavorable, owing to its exiDulsion in an undeveloped condition and to the compression exerted upon it during labor. The prognosis for the mother is favor- able because of the usual small dimensions of the foetus and of the freedom with which measures for the reduction of its volume are re- sorted to in view of its probable early demise. An acardlacus is a monster devoid of the heart. It is developed simultaneously with a normal foetus, and is usually born after the lat- ter. Its development, as already explained,! occurs in the following manner : The balance of circulation in the anastomosing vascular sys- tems of twins contained in a single chorion (and therefore of the same sex) becomes disturbed, and the pressure in one system so preponder- * Spiegelberg, Lehrbuch, p. 531. f Chapter on Multiple Pregnancy. 558 THE PATHOLOGY OP LABOR. ates over that in the other that the circulation of the latter is reversed, and its hearts, lungs, and body atrophy. It now receives its nutritive supplies from the normal foetus. As the result of congestion in its umbilical vein, its connective tissue often undergoes hypertrophy and cedematous infiltration. The same cause may result in hydrocephalus or in the development of a monster presently to be described as an Fig. 220.— Author's case of acardia. anencephalus. The most common variety of acardiacus is known as the acephalus, or headless monster. The amorphus is an acardiacus without head or extremities. It is of rounded form, and its surface, though ordinarily smooth, may present faintly marked tubercles, which are regarded as rudimentary extremities. Tlie interior of the amor- phus contains a rudimentary intestinal canal, cystic cavities, muscles, and vertebrae. The umbilical cord is attached indifferently to any i ABNORMALITIES OF THE FOETUS. 559 part of the body. The rarest form of the acardiacus is the acormiis, or trunkless monster. It consists of an imperfectly devekjped head with a rudimentary trunk. Its umbilical cord is attached to the cer- vical region. An anencephalus or hemicephalus is a monster with a well-devel- oped trunk and a rudimentary head. The neck is short and the head rests directly upon the shoulders, which are so unusually broad as to constitute an impediment to delivery. The amount of amniotic fluid is ordinarily large. The face is turned upward and the eyes are prominent. The most common jjresentations for an anencephalus are the transverse and the breech. Sometimes the face or the exposed base of the skull presents. In such a case the diagnosis may be made by recognizing the sella turcica and other bony prominences of the base. Keflex actions may be produced by irritation of the medulla, as it rests exposed upon the basilar process of the occipital bone.* This deformity produces obstruction by permitting other extremities to enter the pelvic cavity simultaneously with the diminutive head, and by the unusual breadth of its shoulders. The latter are more readily expelled when the parturient canal has been previously dilated by the passage of the breech. IV. Shortness of the CoRD.f Though dystocia from shortness of the cord is of rare occurrence, it should always be regarded as a possible source of delayed labor. Shortness of the cord may be absolute, as in cases where its length does not exceed a few inches ; or a normal, or very long cord, may, by the formation of coils around the foetus, become taut as the foetus is expelled from the uterus. In the preliminary stage of labor the effect of shortness of the cord is sometimes perceptible in the irregular heart-action of the fcetus, in the recession of the head not due to the resistance of the soft parts during the intervals between the pains, and in an interference with the mechanism of labor as characteristic of an early period. In the second stage the effects of the shortening may be experienced at the j^elvio outlet. Usually, however, difficulty is not encountered until after the expulsion of the head. As the result of the tension to which the cord is subjected, it stretches, and, as Duncan points out, some gain in distance from child to placenta is obtained by the drawing out of the two insertions, the navel and abdominal wall on the one hand, and the placenta and uter- ine wall on the other ; or, if the cord encircles the child, length may be gained by compression of the encircled parts. Stretching alone * Herrgott, op. cit., p. 263. f Matthews Duncan, Obstruction owing to Shortness of the Cord, Obstet. Trans., 1881, p. 243; Chautreuil, Des dispositions des cordens, Paris, 1875. 560 THE PATHOLOGY OF LABOR. may permit natural birth to take place. If not, the continued tension may result in the tearing of the cord, in partial inversion of the uterus, or in the separation of the placenta. According to Duncan, the cord yields to a strain equal to five and a half pounds for the weakest, and fifteen pounds for the strongest. AVhen the cord becomes taut during the expulsion of the foetus, the anterior surface of the latter rotates forward so as partially to undo the encircling and diminish the tension. In the completion of the birth the cord lies close to the urethra, and forms a radius around which the body revolves, a movement which Duncan aptly compares to spontane- ous evolution in shoulder presentations. Under these several conditions the fetal mortality is said to be up- ward of twenty per cent. That of the mother is much less serious. Aside from heemorrhages due to placental detachment, and rare in- stances of uterine inversion, the most important consequences are those which result from delayed labor. I have witnessed the following case, which terminated fatally : The patient was a primipara, twenty-two years of age, who, after five days of ineffectual labor, entered the Emergency Hospital. Her temperature was 103"5° Fahr. She was in great agony. The external genital organs were inflamed. The fetal heart had ceased to beat, and meconium escaped from the vagina. The head could be seen through the gaping vulva. After giving ether, I applied forceps, but met with more resistance than I had anticipated. After extracting the head, on passing up the finger I found the cord tense, and coiled a number of times around the child's neck. When about to sever the cord, a sudden pain was followed by the expulsion of child, cord, and placenta together. The next day the external genitals became gangrenous, and on the fifth day the patient iied from a slough in the upper portion of the vagina, which communicated Avith the peritoneal cavity, and had evidently been the result of the long- continued pressure. A positive diagnosis can only be made when the labor has so far advanced that the cord can be felt with the finger. The treatment consists in loosening the coils, where it is possible, or in severing the cord, if accessible, and speedily extracting the infant. During expul- sion the rotation of the child forward may be aided, and assistance may be rendered, by external pressure downward upon the fundus of the uterus. V. Transverse Presextatioxs. In so-called transverse presentations the axis of the child crosses obliquely the axis of the uterus. A horizontal position of the foetus, with both extremities occupying nearly the same level, is the rare ex- ception. Usually the child lies obliquely with the head resting upon an iliac fossa. When the uterus contracts, the shoulder is usually ABNORMALITIES OP THE PCETUS. 561 pressed down into the lower uterine segment; hence shoulder and transverse presentations are frequently employed as synonymous ex- pressions. In shoulder presentations prolapse of the lower arm or of the cord are not of infrequent occurrence. The position of the child with the head to the left, as the more frequent one, is termed the first position ; with the head to the right, the second position. According as the back of the child is directed forward or to the rear, we further distinguish dorso-anterior and dorso- posterior positions. The dorso-anterior position is the usual one. According to Churchill's statistics, the frequency of transverse pres- entations is 1 : 252, Spiegelberg found it 1 : 180, while in France the combined statistics of Depaul, Dubois, and Pinard show a frequency of 1:117 (Charpentier). The causes of this abnormality are to be found in the absence of the conditions which contribute to the fixation of the cephalic extrem- ity. Thus a predisposition is created by an excess of amniotic fluid, by placenta pr^evia, by multiparity, by premature births, by death of the foetus, and by uterine and pelvic deformities. Diagnosis. — The existence of a transverse presentation can usually be ascertained by means of external palpation. Thus, the hard, round head can be mapped out in most cases in an iliac fossa, and the soft breech of smaller size be felt at a higher level upon the opposite side. Upon vaginal examination, the presenting part is commonly felt high up at the level of the brim, so that it is sometimes necessary to intro- duce the half or even the entire hand to arrive at certainty in diagnosis. Great care should be exercised in passing the finger through the cervix for purpos9s of exploration, as it is especially desirable to avoid pre- mature rupture of the membranes. In an early stage of labor the vaginal vault is flattened. With the advance of the first stage the shape of the bag of waters corresponds to the resistance offered by the cervical canal. In multipara, and in all cases where softening and dilatation proceed rapidly, the ordinary globular segment may form in advance of the presenting part; if the cervix remains rigid, the membranes usually make their way through the cervical canal as an elongated pouch, a condition which especially favors the early occur- rence of rupture. Sometimes the diagnosis is made clear by the pres- ence of a prolapsed extremity in the bag of waters. After rupture of the membranes, the shoulder is recognized by feeling the scapula with its spine, the arm-pit, the clavicle, and the ribs, and, in many cases, by means of a prolapsed upper extremity. The position is determined by the direction of the head and of the back. Often these can be made out by external palpation alone ; by vaginal examination, the relations of the scapula and clavicle to the uterine walls, and the direction of the arm-pit, furnish the data for the formation of the diagnosis. If the arm is prolapsed, it may be drawn 36 562 THE PATHOLOGY OF LABOR, outside the vulva. If the hand then be turned with the palm upward, the arm is always of the same name as the side of the mother to which the thumb is turned. If the presenting arm and the direction of the head be known, the position of the back, whether to the front or rear, is readily deduced. Spontaneous Version". The term spo7ifaneons versmi is applied to the process by which either a transverse position is transformed througli Nature's unaided eiforts into a longitudinal one, or to that by which a normal position is either partially or completely reversed. Spontaneous version, which occurs during pregnancy as a very frequent physiological phenomenon, is observed with comparative infrequency during labor. It may be partial or complete, according as the presenting member is displaced laterally through either 90° or 180°, may occur before or after the rupture of the membranes, and may result in the transformation of a transverse position into either a head, a breech, or a footling presenta- tion. According to the statistics of Hausemann,* cases of spontaneous version after rupture of the membranes are nearly five times as fre- quent as those occurring before their rupture. The same author states that the head presented in eighty per cent of the cases occurring be- fore rupture of the membranes, and the breech in seventy-five per cent of those taking place after the occurrence of that event. Spiegelberg f cites two cases from his own practice in whicli tlierc was an escape of so-called "false waters," the real membranes remaining intact, and attributes the occurrence of spontaneous version in such instances to the change of uterine form rendered possible by the evacuation of the false waters. Etiology. — Among the conditions predisposing to spontaneous ver- sion is the uterine atony incident to repeated deliveries. About two thirds of all the women in whom spontaneous version occurs are, ac- cordingly, multiparag,J and their average age is thirty years. Spon- taneous version often recurs during several consecutive pregnancies of the same individual. It is more apt to occur during deliveries effected at term than in abortions or premature deliveries. A living foetus is more frequently the subject of spontaneous version than a dead one, and many authors attribute an important agency in the production of the altered position to the active movements of the child. The uterine contractions are necessarily weak in cases of spontaneous version occur- ring before the rupture of the membranes, as powerful pains would force the presenting part still farther into the dilated os and fix it im- movably in the pelvic brim. On the other hand, the contractions of the uterus during a spontaneous version which takes place after the * Hausemann, Monatsschr. f. Geburtsk., Bd. xxiii. 1864, p. SOfi. t Spiegelberg, Lfihrbuch, p. 539. % Hausemann, loc. cit., p. 213. ABNORMALITIES OF THE FCETUS. 563 escape of the amniotic fluid must be strong, as will be explained in our remarks on the mechanism of the process in question. An undi- lated cervix, powerful contractions of the uterine fibers, and a fully developed child are essential conditions for the occurrence of spontane- ous version after rupture of the membranes. 8ome authors consider the presence of a certain amount of amniotic fluid indispensable to the occurrence of spontaneous version in those cases taking place after rupture of the membranes. It is also necessary in such instances that the shoulder or other presenting part be freely movable, not having yet been firmly fixed in the cervical or pelvic canal. Mechanism of Partial Version. 1. Before Rupture of the Memljranes. — In this case the shoulder usually presents, the head being lower than the breech. The os is only partly dilated. The woman having assumed a position upon that side of her body toward which the head is directed, the breech tends to descend under the influence of gravitation, while the head is thus ap- proximated to the cervix. The contractions of the uterine muscular fibers now complete the version by exerting pressure ujjon the breech. When the uterus has once regained its natural shape, the normal j^osi- tion is retained by the foetus until the completion of parturition. In other instances, the breech being lower than the head, the same mech- anism leads to a breech or to a footling presentation, 2. After RujHure of tlte Membranes. — In this variety of spontane- ous version the amniotic fluid has partially or entirely escaped, allow- ing the foetus to be tightly grasped by the uterine muscular walls, which, therefore, labor under a mechanical disadvantage. The os is only partially dilated. The pains force the presenting part into close contact with the os internum. Owing to the absence of an equally distending bag of waters, the os does not dilate, and soon assumes a condition of tetanic spasm, during which it can be felt as an unyield- ing, cartilaginous ring. The contractions of the fibers at the fundus uteri having now become more forcible, the fetal head or breech, as the case may be, is subjected to violent pressure. Inasmuch, however, as the unyielding os prevents any progress downward, the presenting part is displaced laterally, and that part of the fcetus which previously occupied the fundus is forced into the pelvic entrance. The uterus next regains its natural form, the os dilates, and delivery is accom- plished. Mechanism of Complete Version. Cases of complete version, which are very rare, consist in the trans- formation of one normal longitudinal presentation into the diametrical- ly opposite one, the part originally presenting having rotated through 180°, The mechanism is essentially identical with that just described. 5(54: THE PATHOLOGY OF LABOR. Version of this variety is only likely to occur when the amount of liquor amnii is large and the child small, so that it is freely movable. Spontaneous version before the rupture of the membranes occupies only half the time required for its accomiDlishment after their rupture. Twenty-four or thirty hours are often necessary for the completion of the latter variety. Delivery, too, is accomplished more speedily in cases of the former kind when version has once occurred. Prognosis. — The prognosis for both mother and child is good in spontaneous version before rupture of the membranes, but is graver when the turning occurs after that event, contrasting unfavorably with manual version, owing to the fact that injurious pressure is liable to be exerted upon the prolapsed cord. Labor when the Presentation" remains Transverse. If the transverse presentation continues after rupture of the mem- branes, the entire contents of the amniotic sac escapes, and the uter- ine walls retract down closely upon the foetus, or the shoulder is pressed into the pelvic cavity, the contraction-ring recedes, and the back of the child is forced into the cervix and the thinned lower uterine segment. In the latter case danger of rupture becomes imminent. Usually, if the malposition of the child is not corrected by art, or rupture does not occur, the rigid uterine walls closely compress the foetus, and the mother in the end dies from the ensuing exhaustion, or from metritis, from peritonitis, or from septicaemia. In rare cases, however, spontaneous birth of tJie child may take place by the process termed evolution. Spontaneous evolution is the process by which a shoulder presenta- tion is transformed, within the true pelvis, into a combined breech and shoulder presentation, and spontaneous delivery is then effected. Since this may be accomplished in two different ways, there are two corresponding varieties of spontaneous evolution. The first variety was, according to Leishman,* described by Douglas, of Dublin, as " spontaneous expulsion." Dr. Taylor f takes exception to Leishman's statement, and affirms that the term spontaneous evolution was ap- plied by Douglas to the mode of delivery in question. The second was described by Roderer as " birth with double body " (" evolntio conduphcato corjjore''^), and more thoroughly explained by Klein- wachter.J Etiology. — Various conditions contribute to the facility with which this process is accomplished by Nature. The most important are powerful pains, a roomy pelvis, and a small foetus. Of these condi- tions, the first only is essential; Grenser* has demonstrated that a * Leishman, a System of Midwifery, Philiulelj)hia, 1873, p. 337. f Taylor, Am. Jour, of Obstet..

ABNORMALITIES OF THE FCETUS, 565 contracted pelvis is not an insurmountable obstacle to spontaneous evolution, provided the conjugate diameter be alone shortened. Nor is small size of the fcBtus essential to the occurrence of the process in question. Spiegelberg* states that it is often observed in cases where the foetuses are mature and well developed. Softness and compressi- bility of the child naturally favor the production of spontaneous evo- lution, as is demonstrated by its frequent occurrence when the jDroduct of conception has undergone maceration. Mechanism. — The mechanism of the former and more ordinary variety of spontaneous evolution is as follows : The presenting shoulder is forced into the depths of the true pelvis by the violence of the uter- ine contractions, instead of being diverted laterally, as is the ease in spontaneous versions and becomes firmly fixed beneath the symphysis, while the corresponding arm protrudes through the vulva. The body Fig. 221.— Neglected shoulder presentation. Section through frozen corpse. (Chiara.) of the fffitus is then so forcibly flexed that the breech and the head lie in close proximity to each other. The former is in contact with the sacro-iliac synchondrosis, while the latter is immovably held between the breech and the upper border of the symphysis. The neck and shoulder, which rest against the lower border of the symphysis, now become the pivot upon which the foetus rotates. The trunk of the foetus is driven beyond the shoulder, and the thorax, breech, and legs are born in the order named. The other shoulder then follows, and the head is finally expelled. The mechanism of the second variety of spontaneous evolution, designated by Roderer " evolutio conduplicato corpore^'"' which is much * Spiegelberg, Lehrbuch, p. 541. 566 THE PATHOLOGY OF LABOR. rarer than the former, differs from it in some essential features. It is greatly facilitated by softness and compressibility of the child, and therefore occurs predominantly in cases of macerated foetus. It is rarely observed in other cases, un- less the foetus be unusually small and its tissues greatly relaxed. The shoulder is in this instance forced downward and imprisoned beneath the symphysis pubis, as in the former variety, while the arm protrudes from the vulva. The trunk having been enormously flexed, the head and thorax simul- taneously enter the pelvic cavity, the former being deeply imbedded in the latter. The second arm and shoulder lie between the breech and thorax on the one hand, and the head on the other. The pre- senting shoulder having been ex- pelled, the head and thorax are born together, and these are fol- lowed by the breech and the legs. Prognosis. — The prognosis in spontaneous evolution is good for the mother, but very bad for the foetus, since only immature chil- dren are, as a rule, able to pass through the ordeal of delivery by this method alive. Kuhn, how- ever, has reported a case of a child born alive, weighing four and a half pounds and measuring seven- teen inches in length ; and Simon, according to Spiegelberg, collected one hundred and twenty-five cases in which fourteen children were born living. Three of the one hun- dred and twenty-five mothers died. In the variety of spontaneous evolution known as '-'■ evolutio conduplicato coiyore^'' which occurs in the rule in small or macerated children, the prognosis is especially unfavorable. In these latter cases Dr. Taylor* recommends, when the perinaium is distended by the doubled body of the child, to make lateral incisions to the extent of three to four inches at the vulva, and thus remove the obstacle to delivery afforded by the pehic floor. * Taylor, Am, Jour, of Obstet., July, 1881, p, 532. Fig. 232.— Birth with doubled body. vKleiuwachter.) ECLAMPSIA. 567 CHAPTER XXX. ECLA3IPSIA. Definition. — Clinical history. — Prognosis, pathology, and etiology. — Treatment. Eclampsia is the term applied to convulsions, tonic and clonic in character, the foundation of which is laid in processes connected with pregnancy, labor, and childbed {eclampsia gravidarum, parturientium, ■vel piterperartim). By this definition it is intended to exclude the con- vulsions due to hysteria, true epilej)sy, and cerebral lesions, which oc- currences in pregnancy are to be regarded simply as accidental compli- cations. In eclampsia there is loss of consciousness during the attacks, with at first a disturbance of the intellectual faculties m the intervals, afterward deepening in severe cases into coma. Before entering upon a discussion as to the probable nature of this affection, it is proper to present a summary of its clinical manifestations. Clinical His tori/. — Eclampsia is fortunately a tolerably rare event. Its estimated frequency is in about the j)roportion of once in five hun- dred pregnancies. The total number of deaths from this cause re- ported to the Board of Health in New York city, in the nine years from 1867 to 1875 inclusive, was 408. The estimated maximum num- ber of deliveries during that period was 284,000, or nearly one death to seven hundred confinements. The entire niimber of deaths occurring in pregnant women from all causes during the same period was 3,342, making the proportion of those from eclampsia as one to eight. In the majority of cases, though not invariably, premonitory symptoms announce the impending outbreak. Of these the most important are headache, often limited to one side, vertigo, loss of memory, gloomy forebodings, flashes of light before the e3"es, contracted pupils, ambly- opia, sometimes amaurosis, ringing in the ears, dyspepsia, nausea, vom- iting, dyspnoea, oedema of the face, of the labia majora, and of the extremities, and, finally, and of first importance, the presence of albu- men and of casts in the urine. The attacks resemble those of ej)ilepsy, the cry only lacking. When they occur during labor, the first convulsion often is preceded by a short calm, in which the patient ceases to complain, closes her eyes, and seems to have sunk into a ]3eaceful slumber. This deceitful truce, which should always excite the keen attention of the physician, is fol- lowed in a few minutes by convulsive movements of the orbicularis oris muscle, giving to the patient a smiling aspect. Suddenly the eye- lids open, the eyes become fixed, and the pupils contract. Then, in a few seconds, the eyelids open and shut rapidly, the eyes move from side to side or roll upward, while the pupils dilate and lose their sensi- tiveness to light. Very rapidly the convulsive twitchmgs extend to 568 THE PATHOLOGY OF LABOR. the other muscles of the face, the mouth opens and is drawn to one side, the head is moved from shoulder to shoulder, sometimes with lightning-like alternations. Frequentl}^ for the first two or three con- vulsions, the movements of the extremities are limited to the pronation and supination of the forearm and to the closing of tlie fingers upon the thumb. Afterward the arms, crossed upon the thorax, pass from flexion to extension with great rapidity. The movements, as a rule, are more pronounced iu the upper than in the lower extremities. Sometimes the latter are fixed with tetanic rigidity, while at others they are flexed at the knee and then drop of their own weight, now upon one side, now upon the other. As a consequence of the resulting disturbances in the circulation and respiration, the carotids pulsate with great distinctness, the super- ficial veins of the neck swell, the conjunctivae become injected, and the face is c3'anosed ; the heart's action becomes intermittent, and the breathing irregular and stertorous. In the tonic convulsions, which occur intercurrently with clonic ones, the head is inclined to one side, the mouth is drawn in the same direction, the jaws are closed, the eyes are fixed, opisthotonus or pleu- rosthotonus develops, the pulse becomes small and intermittent, the respiration is suspended, tiie body becomes covered with a cold, clannny sweat, and often involuntary micturition or defecation takes place. The tetanic condition, after lasting from fifteen to thirty seconds, gradually diminishes in intensity. As the convulsions cease, the distortion of the face disappears, the cyanosis diminishes, the eyelids droop, the mouth opens, and frothy saliva, tinged with blood, escapes from the mouth and nostrils. Ster- torous respiration marks tlie beginning of sopor. At first the patient, unless the attack has been of unusual severity, can be roused when spoken to. The depth of the sopor is proportioned to the violence and frequency of the attacks. ^Yhen the convulsions are repeated, the patient in the intervals can no longer be made to respond to inquiries, but passes into a state of complete unconsciousness. The duration of a single attack rarely exceeds a minute, and in a majority of cases lasts from ten to thirty seconds. On account of the implication of the re- spiratory muscles, attacks of long duration are scarcely compatible with continued existence (Spiegelberg). After a single seizure the sopor usually disappears in from one half to two hours, and seldom persists beyond a single day. The number of seizures in a single day may, however, be exceedingly numerous. Thus, seventy convulsions have been reported by Braun,* eighty-one by Brummerstedt,f and one hundred and sixty by Depaul.J * Braun, Lehrbuch der gesaramt. Gynaekologie, p. 822. t Brummerstedt, Bericht, etc., Rostock, 1866. X Vide Spiegelberg, loc. cit., p. 556. ECLAMPSIA, 569 With very rare exceptions — of which, however, I have never seen an example — the urine after the convulsions is found loaded with albu- men, and contains an abundance of renal ejiithelium, often in a state of fatty degeneration, casts, and sometimes blood-corpuscles. In all cases of exceptional severity the urine is scant or absent altogether. Terminations. — In favorable cases, after the expulsion of the ovum the attacks cease or diminish in frequency and intensity, the pulse and respirations become quiet, and the coma passes gradually into gentle slumber. On awakening, the patient complains of headache and of impaired memory, and possesses no recollection of the perils through which she has passed. Pains are felt in the muscles, and in the tongue when the latter has been injured to any considerable extent by the teeth. But even after consciousness returns, the danger is still not ended. Eclampsia predisposes to post-partum haemorrhage and to puerperal inflammations ; or it may leave behind hemiplegia, amblyopia, an en- feebled mental condition, or psychical disturbances, especially mania, which, however, usually terminates spontaneously in the course of the first three days. In fatal cases death results from carbonic-acid poisoning, due to tetanus of the respiratory mu.scles or to exhaustion of the nervous sys- tem. Bailly relates the history of a patient who died of asphyxia, due to swelling of the tongue. Of anatomical lesions found in post-mortem examinations, the most constant are hyperemia, more often an ansemic state, fatty degenera- tion, and atrophy of the kidneys. The latter is rare, and in many cases the renal changes are of moderate extent. In thirty-two examinations, Lohlein * found in eight dilatation of one or both ureters and of the pelves of the kidneys. The same author likewise has demonstrated the existence of enlargement of the heart (the comparisons were instituted with those of other pregnant women), indicative of increased arterial tension. The brain-lesions were in most instances insignificant. Prognosis. — The prognosis is always serious. In Dohrn's collec- tion of 747 cases the death-rate reached 29 per cent ; in 104 cases col- lected by Hofmeier f in Schroeder's Clinic the mortality was 33-4 per cent. A better showing is made by Braun,J who was able to report from Vienna in ten years, from 1869 to 1878, 73 cases, with twenty deaths (26 per cent), five from peritonitis and fifteen from Bright's disease alone. The earlier the convulsions occur in labor, the more unfavorable the prognosis. This is well shown by the statistics of Lohlein. Thus, of eighty-three cases where the first convulsions occurred before or during the first stage of labor, 40*5 per cent of the patients died. Of * Lohlein, Bemerkungen zur Ekhimpsiefrage, Ztschr. f. Geburtsh. und Gynaek., Bd. iv, Heft 1, p. 89. f Hofmeier, loc. cit. | Braun, Lehrbuch der gcs. Gynaek., p. 833. 570 THE PATHOLOGY OF LABOR. fifteen cases where the first stage was completed, but one patient died. Eclampsia, which develops first in childbed, usually pursues a favor- able course. Ldhlein reports eight cases, with one death, which, how- ever, was the result of infection. The longer the labor the more difficult the delivery ; the deeper the coma and the greater the insufficiency of the kidneys the more de- pressing is the outlook. It is very rare for the convulsions to cease previous to the expulsion of the child. According to C. Braun, after delivery in thirty-seven per cent the convulsions cease entirely, in thirty-one per cent they become feebler, while in thirty-two per cent they continue for a time with un- diminished severity. In childbed it is of favorable import when copious diuresis sets in, and is followed by the disajDpearance of tlie albumen and of the oedema. As regards the children of eclamptic women, it is estimated that fully one half are born dead, a result probably due to asphyxia from the accumulation of carbonic acid in the blood of the mother. As the results depend upon the number and duration of the attacks, it is evident that the danger is greatly lessened after the completion of th^ first stage of labor. Pathology and Etiology. — As in discussions upon eclampsia it is evident that the treatment advocated by physicians is governed almost exclusively by theoretical considerations, it becomes of the utmost importance to place before the student an exact statement of known facts, with an attempt to estimate at their true value the deductions which various observers have drawn from them. Now, in the first place, in reviewing the foregoiug history of the disease, we are brought face to face with the very striking coincidence in the vast majority of cases between renal insufficiency and the con- vulsive seizures. This insufficiency may or may not be associated with albuminuria, though the two go jiretty constantly together. The honor of first drawing attention to the relations between albuminuria and puerperal convulsions belongs to Dr. John C. AV. Lever, who re- ported in Guy's Hospital Reports, second series, 1842, fourteen cases, in ten of which the urine was examined. Albumen was found in greater or less quantity in nine cases ; in the post-mortem made in the tenth case the death was discovered to have been due to acute memngitis.* These observations were followed by others from British physicians, among whom may be mentioned Simpson, Garrod, Cormack, and Eses; and in France treatises upon the subject Avere iDublished by Cohen and Delpech, and by Devilliers and Eeguault. * Vide Tyson, The Causal Lesions of Puerperal Convulsions, Philadelpliia, 1879. To this excellent summary I desire to acknowledge my indebtedness for a deal of labor saved, as regards the search for references. ECLAMPSIA. 571 In 1851 Frerichs pointed out clearly the close resemblance between the convulsions occurring in pregnancy and the ur^emic convulsions of Bright's disease. After reviewing the evidence with scientific pre- cision, he concluded that " true eclampsia occurs only in pregnant women suffering with Bright's disease, and it bears to the latter the same causal relation as convulsions and coma in Bright's disease in general ; it is the result of the uraemic intoxication, with which also in its mode of manifestation it agrees." To this view Braun, in the same year, and Wieger, in 1854, brought effective support by the pub- lication of a great number of observations confirmatory, both in re- spect to the clinical features and the j^ost-mortem appearances, of the uraemic origin of puerperal convulsions. In 1857 Braun published one of the most meritorious treatises upon midwifery to be found in any language. In this work the new doctrine was presented with so much skill and clearness that since then, in the minds of the great body of practitioners, the terms eclampsia and uraemia have come to be regarded as synonymous. In order to understand the present position of the question, it is necessary to review the objections which the uremic theory has had to encounter. Among its earliest opj)onents was Seyfert, of Prague, who occupying the vantage-ground as director of the maternity hospital of that place, second only in size to the great maternity at Vienna, furnished the clinical counter-experiences which have since proved the most effective weapons in the hands of those who have regarded the new doctrine as specious and heretical. The facts which, he insisted, invalidated the claims of Frerichs and Braun were as follows : * 1. That convulsions may occur without albuminuria. 2. That the albuminuria is in many cases the effect and not the cause of the convulsions. 3. That in many fatal cases the kidney-lesions were absent or wholly insignificant. 4. That convulsions are rare in chronic Bright's disease which had existed prior to pregnancy. 5. That in true ursemia, such as necessarily is produced by the sujjpressiou of urine when, in uterine cancer, the ureters are invaded, convulsions do not occur. That, in the main, these propositions are correct, hardly admits of question. But, in drawing conclusions from these, unnecessary stress is laid upon the presence or absence of albumen in the urinary secre- tion. It is the renal insufficiency, it should be fixed in the mind, and not the albuminuria, which is associated with convulsions. The mere * As T hiive copied this list from notes taken from the lectures of Seyfert, delivered in the summer session of 18G5, I shall not consider it necessary to more than incidentally refer to the corroborative testimony since advanced m support of their validitv. 5Y2 THE PATHOLOGY OF LABOR. absence of albumen from the urine does not even exclude the existence of Bright's disease. Braun is careful to note that in certain cases of fatal eclampsia, in spite of the absence of albuminuria, the post-mortem examination revealed amyloid degeneration of the kidneys and of the heart-structures ; and, again, in others, of atroi)hy of both kidneys, where the dropsy, and the albumen, and casts, wliich had been present earlier in pregnancy, had entirely disappeared at the moment the con- vulsions occurred. Bailly has shown that not rarely albuminuria in pregnant women may disappear for several hours and then reappear once more, so that it is possible for an examination to be made during the short period when the urine ceases to be albuminous. On the other hand, chronic nephritis does not necessarily imply in- sufficiency of the renal secretion. Seyfert reported over 70 cases where women suffering from Bright's disease became pregnant ; only two of these had convulsions. Every observer has seen similar instances of immunity. Nephritis in pregnancy brings with it its own peculiar dangers. Of forty-six cases, chronic in character, reported by Ilof- meier, only one third of the patients had eclampsia, but one half died. Including acute and chronic cases together, Braun estinuitcs that only sixty in the hundred develop uriemic convulsions. Ilofmeier found, in five thousand births recorded upon the history-books of the Berlin Clinic 137 cases of nephritis entered. Of these, 104 patients only were attacked with eclam])sia. Professor Bamberger* reports from autopsies of the " allgemeinen Krankenhaus " in twelve years 2,430 cases of Bright's disease, of which 152 were found in puerperal and pregnant v/^omen, viz., 80 acute cases, 56 chronic cases, and IG cases of atrophy ; puerperal eclampsia was recorded in 23 instances. Flaischlen f found in examining 1,000 cases of pregnancy that albu- men was present in twenty-six. In five of the cases the patients suf- fered from catarrh of the bladder, and in two chronic nephritis was diagnosed, leaving nineteen per thousand in whicli albuminuria was dependent upon pregnancy. Of 537 cases (205 primipars, 242 multi- paras) observed during labor or immediately after childbirth, albumi- nuria was present in 93 women, of whom 73 were primiparte and only 20 were multipara. As the estimated frequency of eclampsia is only 1 to 500 cases of pregnancy, the mere presence of albumen is not neces- sarily of grave prognostic importance. Lohlein examined the records of thirty-two autopsies made upon eclamptic women, and found in eight, or in twenty-five j^er cent of the entire number, that dilatation of one or both ureters coexisted with renal disturbances. He, therefore, pertinently inquires how far sim- * Bamberger, Ueber Morbus Brightii und seine Beziehungen zii anderen Krank- heiten, Volkraann's Saraml. klin.

ECLAMPSIA. 573 plo mechanical obstruction of the ureters may explain the apparent development of urEemic manifestations in certain cases without the warning furnished by albumen in the urine. Finally, it is not claimed by even the most stalwart champions of the urtemic nature of eclampsia that the convulsions which occur dur- ing pregnancy and labor are invariably the result of the same cause. Thus, Tyson says : " There are no reasons why we should exclude from the causes of the convulsions in the puerperal state those which op- erate to produce convulsions in the non-puerperal condition." So- called cases of eclampsia without albuminuria, i. e., without unemia, are admitted by Braun and Spiegelberg, and referred by them to reflex stimulation of the vaso-motor and convulsive centers (Krampfcentren). They advocate, however, separating them off into a class by them- selves under the title of acute epilepsy, or eclamptiform attacks, a distinction they believe warranted by their rarity and their benio-u be- havior. The objection drawn from the insignificance of the kidney changes, frequently observed in post-mortem examinations, loses most of its force when we remember that in a large proportion of cases the reten- tion of excrementitious materials is due to acute suppression. Thus, in the 104 cases of eclampsia reported by Hofmeier, the kidney symp- toms developed suddenly. This sudden suspension of the urinary se- cretion can only result, Spiegelberg* argues, from disturbances in the renal circulation. A rapidly developed affection of the vessels would leave no marked post-mortem traces, and would, in cases of recovery, disappear as quickly as it had come. Were the kidney troubles due principally, as was formerly supposed, to pressure of the gravid uterus upon the renal veins, the kidneys should, in. post-mortem examinations, exhibit evidences of congestion ; whereas, usually they are, on the con- trary, found to be pale and anaemic. Besides, in cases of pressure from ovarian and pelvic tumors it is usually the ureters and not the veins which are implicated. The precise nature of the circulatory changes is not, of course, definitely known. Spiegelberg suggests that either the walls of the vessels are altered in such a manner as to interfere with the process of diffusion, or that a reflex contraction of the vessels due to a peripheral stimulus operates to cut off the blood-supplies to the kidneys. Frankenhaeuser, having demonstrated a direct connec- tion by means of the sympathetic nerve between the ganglia of the kidneys and the nerve-filaments of the uterus, had likewise suggested in effect that the albuminuria of pregnancy was due not to pressure but to the excitation of the uterine and renal nerve plexuses. Cohnheim supposes that the renal changes of pregnancy are due primarily to reflex contraction of the arterioles of the kidney, and that the albuminuria and the epithelial degeneration are secondary phe- * Spiegelberg, Lehrbuch, p. 561. p^^^ THE PATHOLOGY OF LABOR. nomena. Experimentally, Litten has shown that similar resnlts follow upon the temporary narrowing of the renal afferent vessels by means of ligatures.* The statement contained in the fifth proposition relates to a curi- ous fact, which has since received confirmation from the pathological investigations of Cornil and Kanvier. In a very large proportion of women who had died from uterine cancer the ureters were found oc- cluded, with attendant dilatation and in some cases with hydrone- phrosis. Of these Cornil wrote : " With these obstacles to the excretion of urine we expected uraemic symptoms to be manifested, but they were not. Although the attention of M. Charcot and myself was fixed upon this point, we never saw either the epileptiform convulsions or the coma peculiar to uremic poisoning." A very different interest attaches itself, however, to the inquiry as to the causes of the outbreak of convulsions. It is well known that not every case of nephritis, or even of kidney insufficiency, is followed by eclampsia, though convulsive attacks are much more common in the uriBmia of pregnant than of non-pregnant women. Frerichs be- lieved he had found the secret in supposing a ferment to develop in the blood, which converted the urea into carbonate of ammonia. In 1870 Spiegelberg reported an examination of the blood of an eclamp- tic woman by the latest methods, and demonstrated the presence of ammonia in quantities sufficient to give color to the supposition of Frerichs ; but, subsequent investigations proving negative, he con- cluded that " ammoniiemia is to be regarded as one of the rarest causes of convulsions." An apparently much more scientific explanation was afforded by the now well-known Traube-Rosenstein theory, which maintained that eclampsia took place when, in persons rendered hydraemic by the loss of albumen, the aortic pressure was suddenly increased, the increased pressure giving rise successively to oedema of the brain, then to sec- ondary compression of the vessels, and finally to acute anasmia. An anaemic condition of the hemispheres would, it was predicted, produce coma, while convulsions would ensue if the condition extended to the motor centers. The plausibility of this hypothesis was increased by the widespread acceptance of the doctrine taught by Andral and Gavarret, that the blood of all pregnant women is hydra3mic, and by the fact that the existence of increased blood-pressure during the pains seemed naturally to account for the frequency of convulsions in labor. For a number of years after the announcement of the Traube-Rosenstein theory it received from me complete acceptance; but my faith became after- ward weakened by failing to find at post-mortem examinations the an- * OsTHOFF, Beitrage zur Lehre von der Eclampsie und Uraemie, Sammlung klin. Vortrage, No. 206, p. 1911. ECLAMPSIA. 5Y5 ticipated brain- changes, viz., oedema, anaemia, and flattening of the convohitions. In nineteen examinations, Lohlein reported these alter- ations in but a single case. In his Lehrbuch der Geburtshtilfe Spiegel- berg sums up the objections in a somewhat contemptuous fashion. First he asks why, if the pathogenetic symptoms, as assumed, are in- variably present, eclampsia is of such rare occurrence, and in what way the theory in question affords any explanation of eclampsia in pregnancy and childbed : then he denies that eclamptic women are for the most part hydrgemic, that hydrgemia and arterial pressure are capable of inducing cerebral anaemia, and that the clinical evidences afforded by the pulse and pupils are those produced by oedema. Angus Macdonald reported in 1878 that in the examination of the brain in eclamptic persons he found the meninges congested and the venous sinuses filled with blood, while at the same time there Avas marked ana3mia in the deeper layers of the brain-structure. The ven- tricles, in place of being empty, as should have been the case accord- ing to the Traube-Rosenstein theory of oedematous swelling, were found filled with serum. In place of the doctrine of secondary com- pression, he expressed his belief that the anaemia resulted from arterial contraction due to irritation of the vaso-motor centers from excremen- titious principles retained in the circulation by the insufficiency of the kidneys. The ingenious theory of Macdonald, however, still leaves unexplained the absence of convulsions in cases where the tissues are necessarily loaded with urea, and their occurrence in instances where either no kidney lesions were present, or where the kidney and cere- bral symptoms were coincident. The disposition to ascribe conAiilsions to cerebral ansemia is based upon the experiments of Kussmaul and Tenner, who demonsti'ated that convulsive twitchings might be produced in animals by tying the carotids or by opening the large vessels of the neck and allowing them to bleed to death. It is, of course, anticipated that anaemia due to systole of the arterioles would be followed by the same results. The phenomena of convulsions are twofold, viz., loss of consciousness and tonic and clonic contractions. Loss of consciousness is easily to be ac- counted for by anaemia of the hemispheres, precisely as in cases of ordinary syncope. Convulsions occur, however, when the brain is re- moved, if only the pons Varolii and the medulla oblongata are pre- served. Deiters has shown that the motor fibers of the extremities and the trunk have their first central terminations in the pons. Noth- nagel * has proved that a collection of ganglionic cells in the substance of the pons furnishes the motor center from which the convulsive im- petus takes its departure. According to Schroeder van der Kolk, the groups of gray matter for the cranial nerves are situated in the floor * NoTHNAGEL, Ileber den epileptischen Anfall, Volkraann's Samral. klin. Vortr,, Xo. 39, p. 313. 576 THE PATHOLOGY OP LABOR. of the fourtli ventricle and in tlie substance of the medulhi oblongata. Any influence producing contractions of the arterioles through the vaso-motor nerves would necessarily produce both coma and convul- sions. As, however, convulsions may take place without loss of con- sciousness, Nothnagel concludes that the same cause which acts indi- rectly through the vaso-motor nerves may independently set in action the centers of muscular movements. The foregoing considerations have led writers to divide convulsions into two classes, viz., those due to centric causes and those proceeding from peripheral irritation. In both, cerebral anaemia plays an impor- tant part. In the overwhelming proportion of cases, uremia is re- garded as the fountain and origin of the evil, the term urmnia signify- ing, of course, the action, not of a single constituent of the urine, but of all the excrementitious principles, combined with that of increased arterial tension. Whether, in exceptional cases, carbonate of ammonia or cerebral oedema is present, is a matter of slight moment. The role played by peripheral irritation is not, however, to be overlooked. Without ureemia, though rarely, peripheral irritation can provoke eclampsia. In uremic cases the greater proportion develop during labor. In Lohlein's collection, a hundred and six in number, ninety- three of the patients were parturient. Spiegelberg has frequently seen convulsions awakened in the placental period by the mechanical irritation of the uterus during the employment of the Crede method of expression. It may be assumed that the special source of irritation is derived from uterine contractions, which the observations of Braxton Ilicks and Frommel show are not confined to the time of actual labor, ])ut occurs spontaneously during the entire duration of j)regnancy, aiul continue through the retrograde changes of tlie childbed period. Osthoff,* indeed, concludes that all cases of eclampsia have equally a •reflex origin. Thus, an irritation jiroceeding from the uterus may be transmitted through the sympathetic nerves to the kidney alone, ex- citing contraction of the arterioles or, when sufficiently intense, it may travel upward to the vaso-motor center in the medulla oblongata, and be followed by contractions of the arterioles of the entire body. Evidence of such general contraction is sujjplied by the high tension and slug- glishness of the pulse, while the resulting anaemia of the great nerve- centers furnishes the occasion of the epileptic attack. The advantage of this formula as a working hypothesis is that it renders intelligible what the uraemic theory has failed to do, the occur- rence of eclampsia without kidney lesion, the frequent presence of kid- ney derangement without eclampsia, and the special gravity of eclamp- sia when complicated by kidney derangement. In questioning the * Osthoff, Beitrage zur Lehre von der Eclampsie unci Uraemie, Volkmann'sehe Saramlung klin. Vortrage, No. 29G. ECLAMPSIA. 577 connection between uraemia and eclampsia, the danger to life from the retention in the circulation of excrementitious materials is in no wise disputed. Convulsions occur more commonly in primiparge than in multi- parfB, especially in elderly primiparas, in twin pregnancies, and in women with contracted pelves. They may occur epidemically in con- sequence of atmospheric conditions, which probably interfere with the functions of the skin, and thus indirectly increase the labor thrown upon the kidneys. Treatment. — The occasional examination of the urine of pregnant women is to be regarded as an indispensable precaution. Faint traces of albumen are not infrequently found in the urine of women with harmless catarrhal affections of the bladder. Persistent albuminuria calls for special prophylactic treatment ; for, though convulsions are not to be regarded as the necessary consequence of nephritis, the pres- ence of renal disease immensely increases the danger of sudden acute suppression. Nephritis is, moreover, apt to be aggravated by the pregnant state, and Hof meier has shown that in a considerable pro- portion of the cases which have their origin in pregnancy the kidney- lesions, contrary to the accepted belief, do not disappear spontaneously after parturition. Flaischlen has, however, recently challenged Hof- meier's conclusions. The true renal lesion of pregnancy he regards as due to anasmia of reflex origin, the primary consequence of which is anatomically an alteration in the epithelium of the glomeruli, and clinically albumen in the urine without sediment. In its subsequent course degenerative changes take place in the epithelium of the cana- liculi, and great quantities of albumen with cylinders and epithelia are found in the urine. It occurs first about the middle, or, more fre- quently, toward the close of pregnancy. As distinguished from chronic nephritis, in which the specific gravity of the urine is low and the quantity increased, the specific gravity is high and the quantity dimin- ished. The transition of this form into chronic nephritis he regards as not proved, and a priori improbable.* Every precaution should be taken, therefore, to remove from albu- minuric patients all sources of mental excitement, to ward off attacks of indigestion, and to defend them from colds. In oedema of the face, the extremities, and the labia majora, a strict milk diet should be en- joined, and the tincture of the chloride of iron, in full doses, should be given at least four times a day, both for its diuretic and for its hsem- atinic properties, and likewise to improve the tomis of the weakened vessels. If the milk diet is badly supported by the patient, she should be instructed to drink freely of the natural alkaline waters possessing mildly diuretic properties, such as the Vichy, the Selters, the Buffalo lithia-water, the Poland water, and others of like action. To remove * Ztschr. f. Geburtsh. unci Gynaek., vol. viii, p. 354. 37 578 THE PATHOLOGY OF LABOR. the transuded serum, the skin should be compelled to aid the kidneys, either by means of the Turkish bath or, where the latter is not avail- able, by the wet-jDack. Mild laxatives, such as the Friedrichshall, the Hunyadi, or the Saratoga Avaters, are useful in constipation of the bowels. If cerebral symptoms threaten the outbreak of convulsions, the nervous irritability should be held in check by rectal injections of chloral and the bromide of potassium (thirty grains each), and a hy- dragogue cathartic should, be promptly administered. Free catharsis unloads the blood of urea, diminishes the arterial tension, and relaxes the arterioles. The immediate results are usually in the highest degree satisfactory. The pain in the head, the sensory disturbances, the stomach troubles disappear, and the patient becomes calm or sinks into a gentle sleep. Lohlein recommends placing the woman in the latero-prone position, in order to diminish as much as possible the pressure upon the ureters and upon the renal veins. So far writers are practically unanimous. Whatever differences exist between them relate not to principles, but to the means best adapted to accomplish the end in view. When, however, in sjiite of palliative measures and hygienic precautions, the uraemic symptoms have steadily progressed until the central nervous system has become involved, the question comes uji for decision whether to i:)ersevere in a plan of treatment designed merely to ward off impending danger, or whether to place the patient without delay in a position of relative safety by the induction of premature labor. The weight of authority, it seems to me, is favorable to procrastination, the interruption of pregnancy being regarded as an extreme measure, justifiable only in cases of utmost peril. But premature labor with the indications thus limited, is not likely to save many lives. My own convictions are clear that, so soon as grave cerebral symptons develop, the period of folded hands has passed. The relief to be obtained from chloral and catharsis is, as a rule, of short duration, and we can not go on giv- ing chloral and cathartics to the end of gestation, nor are we sure that the first fortunate results can be reduplicated. Moreover, it is necessary to take cognizance of the well-being of the foetus, which is threatened by the continued circulation of urea in the maternal blood. The induction of premature labor by means of the bougie, aided, if needful, by the vaginal douche and the dilating bags of Barnes, is at- tended with but moderate risk if resorted to after the uraemic symp- toms have been got fairly under control ; if employed as a last re- source, where other therapeutical measures have failed, its use is still justifiable, though it then partakes rather of the nature of a forlorn hope. The indications for treatment during the outbreak are for the most part the same as laid down for uremic symptoms unattended by con- ECLAMPSIA. 579 vulsions, viz., to lower the arterial tension, to diminish to the fullest extent practicable the irritation of the vaso-motor and convulsive cen- ters, and to restore to the kidneys their normal functions. Spiegel- berg claims that these three indications are most completely fulfilled by venesection. Professor Fordyce Barker pleaded for the restoration of the lancet in the management of puerperal convulsions, insisting upon the unmistakable clinical evidences favorable to its employment. In my student-days in Paris, at the Hopital des Cliniques, where the an- cient usage was in full favor, I well remember my first feelings of alarm at the vigor of the treatment in vogue ; but, after carefully watching the cases to the end, I was led to conclude that the claims of bleeding in eclampsia rested upon a substantial foundation. The special advantage of venesection lies in the rapidity of its ac- tion ; incidentally it favors absorption and renders the patient more susceptible to the influence of other remedies. It forms, therefore, naturally the first step in the treatment of convulsions. The quantity of blood to be withdrawn varies from eight to sixteen ounces, accord- ing to the vigor, and, to some extent, according to the size, of the indi- vidual. In the May number of the American Journal of Obstetrics, 1871, Dr. H. Fearn, of Brooklyn, contributed an article on Veratrum Viride in Large Doses, as a Substitute for Bloodletting in Puerperal Convulsions, in which he recom- mended the tincture of veratrum in doses varying from fifteen minims to a tea- spoonful, repeated every five or ten minutes until the pulse became soft, or vomiting set in. For several hours after the convulsions are arrested he ad- vises the veratrum to be administered in smaller doses, in order to keep the pulse below fifty to the minute. He claims that the large doses are devoid of danger so long as the convulsions continue. According to Kenyon,* who has recently contributed two cases successfully treated by veratrum, " the drug is quickly absorbed, and enters the circulation rapidly. It enters the vasa vasorum, and through them impairs the sensibility of the vaso-motor nerves, the blood- vessels thus losing their tonicity and power of contraction " — all good argu- ments for its use in convulsions if its safety can be established. After bleeding, narcotics and anaesthetics should he resorted to, with a view of preventing the renewal of the convulsions. Chloroform and morphine have long been tested in practice, and have sustained their claims to professional favor. From one sixth to one fourth of a grain of morphine should be injected hypodermically, the same quantity to be repeated in an hour in case of the convulsions returning. Chlo- roform was formerly recommended in full anaesthetic doses, so as to completely paralyze the motor centers. As, however, experience has shown that complete and prolonged anaesthesia is in itself a source of danger, it is advisable, except in cases where labor is nearly at a close, * Kenyon, Treatment of Convulsions with Veratrum Viride, N. Y. Med. Jour., October, 1879, p. 370. 580 TPIE PATHOLOGY OF LABOR. to restrict the chloroform to the pains, and to the restlessness which is often the preliminary of a fresh seizure. The discovery of chloral has added another invaluable agent to our list of available antispasmodics and anfesthetics. It is my present practice, after beginning with chloroform, to administer thirty grains, each, of chloral and bromide of potassium by the rectum, and to sus- pend the chloroform so soon as the sedative effects of the latter agents become developed. The frequency with which the chloral should be given depends upon the frequency and violence of the attacks. A single dose will sometimes exercise a restraining influence for hours, while in other cases in the course of an hour or two the dose will require to be repeated. As a subsidiary measure, with a view to the ultimate relief of the kidneys, the lower bowel should be cleared out with an enema, and a cathartic (a drop of croton-oil, or calomel and Jalap in case the patient is able to swallow) should be given by mouth. Breus* warmly recommends the use of the hot bath as a prophy- lactic measure in the renal affections of pregnancy, and as a measure of treatment in conjunction with chloral during the eclamptic attack. The plan he recommends consists in placing the patient up to the neck in a bath of a temperature at first of about 102°, which should be gradually increased to 110° or 112° Fahr. The bed for the reception of the patient should be spread with two blankets covered by a warmed sheet. After a half-hour the patient should be removed from the bath, wrapped in a warm sheet, and placed upon the bed. She should theu be enveloped in the blankets with only the face free, and two more blankets should be laid above the preceding. In a few minutes profuse perspiration sets in, and should be maintained for from two to three hours The covers should then be removed gradually. Foi thirst he gives soda or other sparkling waters. After the sweating, the patients ordinarily sleep a few hours, when they feel well. A comatose condition is no contra-indication, but renders the procedure more difficult. The diaphoresis rapidly diminishes the dropsical symp- toms, and is followed by a decided diminution in the amount of albu- men in the urine. As convulsions which occur after the advent of labor have a tend- ency to recur so long as the labor continues, and in the larger propor- tion of cases cease after the birth of the child, every obstetrical re- source compatible with the safety of the mother should be employed to hasten delivery. In the early part of the first stage the pains, if sluggish should be stimulated by catheterization of the uterus. Braun advocates rupturing the membranes, as he claims that the escape of the amniotic fluid often diminishes the frequency and violence of the convulsions. The water-bags of Dr. Barnes, if necessary, should be * Breus, Zur Therapie der puerpcnileii Eeliiiiipsie. Arch. f. Gvnaek., vol. xix, p. 219. POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA. 581 used to promote the dilatation of the cervix. Incisions through tlie border of the os externum and accouchement force are unnecessary. After the first stage is completed, if no mechanical disproportion exists between the head and the pelvis, a careful attempt to extract the child with forceps should be made. Every precaution should be used to avoid injuring the softs parts. Obstetrical aid is only warrantable where it can be employed without detriment to the mother. In in- strumental cases, with the head high in the pelvis, I have had every reason to feel satisfied with the Tarnier forceps, exchanging it, how- ever, for one of English pattern so soon as the head is brought to the floor of the pelvis. When convulsions occur during pregnancy, the question as to the advisability of at once provoking labor is by no means settled. The material upon which to form an opinion is limited, as in most cases labor-pains occur spontaneously (as a consequence of the convulsions). Where medical treatment alone is employed it is certain that, in the absence of labor-j^ains, a certain proportion recover, and pregnancy may go on to comi)letion. On this account it is commonly advised not to introduce labor as a complication into a state of affairs already sufficiently dangerous and difficult to manage. So far as my own experience goes, however, the practice of waiting upon Nature has proved uniformly disastrous, while the induction of labor has furnished me with a certain proportion of recoveries. Braun declares he has known but one patient to recover between the fourth and sixth months of pregnancy except where abortion had taken place. The question is one, however, concerning which there exists a reasonable degree of doubt, and which can not be settled by the hap-hazard experiences of individuals. In the treatment of convulsions during the childbed period the agents used should be opium, chloral, veratrum, or digitalis. Chloro- form and venesection should be employed with extreme caution, if, indeed, they are ever entitled to confidence at that time. CHAPTER XXXI. POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA.

The haemorrhages which occur immediately after the birth of the child may have their origin in the uterus, the vagina, or the vulva. It is customary, however, to consider those which spring from lacera- gg2 THE PATHOLOGY OF LABOR. tions in a chapter by themselves, and to apply the term post-partum to those hemorrhages only which arise from the placental site. Unlike other grave complications of childbirth, ^jos^^ar^iow haem- orrhage is not an uncommon event. It may follow the simplest of labors, and, in case of an unprepared physician, it may carry his patient in a few moments to the brink of death.- It is impossible to conceive a tragedy more terrible than this. Occurring, as the accident does, suddeiily, without warning, in the period of joy that follows the birth of a living child, the sudden shifting of the scene becomes appalling. If the mother dies at such a time, the luckless attendant who stands at her bedside, a nerveless spectator, need never expect forgiveness ; nor can he shield himself behind the recorded ill-successes of others. Every competent accoucheur knows in his own heart that he has no right to shirk his personal responsibility in cases of fatal jjost-jjartuni hsemorrhage, or to meanly throw the blame upon Providence. The treatment of post-partum haemorrhage is one of the most sat- isfactory departments of obstetrical practice. In no other emergency is the saving of life so little dependent upon chance, and so much upon intelligent human intervention. Successful treatment is, however, less the result of a . familiarity with the various procedures extolled by writers, than of a correct understanding of the mechanism by means of whicli the arrest of the ha?morrhage is to be effected.

The torn arterial twigs retract spontaneously, the patulous mouths of the veins become plugged with fibrinous clots, while the so-called ve- nous sinuses, which are simply channels lined with endothelium, with- out valves or walls, become bent, flattened, and obliterated under the compression exerted by the muscular structures of the uterus. The first requisite against ha?morrhage is the maintenance of firm uniform contraction of the uterus. The contractions, which persist with lessened force after the birth of the child, during their continu- ance alone suffice to prevent haemorrhage from the placental site. The two diagrams borrowed from Professor Breisky serve to illustrate the mechanism by which this is effected. In the transition from a to h the uterus, which shortly before harbored the entire ovum, becomes reduced to a body not larger than the two fists. But the duration of the contractions is short, with an ever-increasing interval between them. If their cessation were followed by the return of the uterus from h to a, the blood would once more rush into the sinuses, the mouth of the veins would open, the thrombi would be washed out by the pressure brought to bear upon them, and flooding would of neces- sity ensue. That this does not take place is owing to the same force which in labor keeps the uterus closed upon its contents during the descent of the foetus— viz., tonic retraction. POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA. 583 The tonic retraction of the uterus is in part the consequence of shortening of the muscuUir fibers, and in part of tlieir rearrangement, a tliickening of the uterine walls resulting, as the cell-elements, in place of standing end to end, assume a position more nearly parallel to one Fig. 223. another. Retraction is a permanent acquisition of the uterus, and alone suffices to prevent the occurrence of haemorrhage. The differ- ence between it and contraction is exhibited by the difference in the consistence of the liost-partum uterus during and between the pains. The contracted uterus is hard and firm like a billiard-ball, while the retracted organ is relatively soft and relaxed. The two properties, though distinct, are not, however, independent of one another. When- ever the contractions are good, the retraction is well marked also. Whatever diminishes the contractile powers of the uterus is followed .by a corresponding falling off as regards its retraction. In cases where the muscular structures of the uterus fulfill their normal functions, the formation of thrombi is of subordinate impor- tance as a means of arresting haemorrhage. Confined to the adherent portion of the decidua serotina, they impart an uneven surface to the placental site. Thrombi which extend to the intermuscular veins are pathological. It is only when the uterus is flabby, and the muscular action is in default, that the thrombi exercise any marked influence in the control of haemorrhage, and even then they bear so close a rela- tionship to puerperal thrombosis as to approach dangerously near to the confines of pathology. The causes of post-partum haemorrhage are to be sought for in dis- turbances of the mechanism by which haemorrhage is normally pre- vented. Disturbances of Contractility. — Contractions of the uterus may fail gg^ TtlE PATHOLOGY OF LABOR. from lowering of the muscular irritability. Atony follows most fre- quently exhausting labor, artificial deliveries, rapid evacuation of the uterus, especially in multiparse, where the failure to contract has often the significance of a prolonged pause, excessive distention (hydram- nios, twins), profuse haemorrhages, collapse, nervous depression, and severe general ailments. Again, in other cases, the functional disturbance may proceed from some abnormal condition of the muscular fiber. Thus, the defects of contractility may spring from incomplete development, as in anoma- lies of formation, in textural changes due to some antecedent disease or puerperal condition, especially as to the result of many previous confinements, or finally from inflammatory infiltrations having their source in the bruising of the lower uterine segment during labor. The contractions of the uterus may be mechanically interfered with over limited areas by retained portions of the placenta and of the membranes, by peritoneal adhesions, by tumors in the walls of the uterus or in the uterine appendages, or by a distended bladder or rectum. Disturbances of Retractility.— AVe have already seen that the tonus of the muscular fibers is lowered, and that their rearrangement is in- complete, whenever the uterine contractions are in default. At the same time the retraction of the uterus may be directly hindered by mechanical causes, especially by those which, like the placenta, the ■membranes, or coagula of blood, when retained in the uterine cavity, prevent, in spite of continued contractions, a sufficient closure of the veins. Disturbances in Thrombus Formation. — The disturbances whicli interfere with the formation of thrombi occur for the most part in those cases in which, owing to the defective action of the muscular structures, the blood-stream arrives at the mouths of the vessels with unchecked rapidity. As a consequence, coagulation does not take place, or the coagula are of soft consistence, and ofter but feeble resist- ance to any sudden increase of blood-pressure, or become mechanically detached by restless movements on the part of the patient, or by strain • ing with the abdominal muscles. Outlying Causes of Post-partum Haemorrliage.— The remote causes of post-partum haemorrhage — i e., those not immediately connected with the uterus — all act by indirectly interfering with either the con- tractility or the tonus of the muscular fiber, or with the thrombus for- mation. This they do by influences exerted either through the nerv- ous system or through the circulation. Thus, the muscular irrita- bility may be impaired by general debility, by wasting diseases, from impoverishment of the blood due to suffering and muscular effort, from psychical impressions, and from the external influences of heat and vitiated air. The normal tonus of the uterine muscles may be over- POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA. 585 come, and the formation of thrombi disturbed, by any condition of the circuhitory system associated with increased pressure in the venous or arterial trunks. The pressure in the uterine veins may be augmented by the patient's getting up suddenly in bed, by acts such as coughing, laughing, sneezing, vomiting, and defecation, in which the abdominal muscles are called into play, and by all the conditions which pro- duce chronic congestion of the pelvic organs. Increase of arterial tension as a cause of haemorrhage is rare. Breisky mentions a case where, in a multipara without valvular heart-disease, the cause of the haemorrhage was apparently due to intense palpitation of the heart associated with the hard, incompressible pulse indicative of arterial fullness.* Treatment. — It is not necessary to dwell upon prophylactic meas- ures. As has been shown in the survey of the causes of post-partum hcemorrhage, they comprise everything that has been said concerning the proper management of labor. Methods of securing Uterine Contractions. — It is my own practice, and one I would urge upon others, to make provision in the simplest of cases against the possible occurrence of hajmorrhage. In the be- ginning of the second stage, I examine my Davidson syringe to make sure that the valves are in good working order. I then direct a small table to be set by the bedside of my patient, and place upon it a bowl containing pieces of ice of about the size of a hen's-egg, brandy, sul- phuric ether, neutral perchloride of iron, carbolic acid, ergot, a solu- tion of morphia, a can of iodoform gauze, and a hypodermic syringe filled with a fluid extract of ergot or two grains of ergotin in solution. Within easy reach I likewise have placed a pitcher of hot water, another of cold water, an empty basin containing the Davidson, or, still better, a fountain syringe, and a bed-pan. All this requires but a few moments' time, and it is of no mean advantage to feel, in case haemorrhage follows the birth of the child, that all the appliances for prompt action are in order and close at hand. If hemorrhage takes place, in spite of the fact that the uterus has been carefully guarded by external pressure during the period of de- livery, draw the pillows from under the head of the patient, direct the nurse to open the windows, and ijiject the ergot contained in the hypo- dermic syringe into the outer surface of the thigh. Ergot by the mouth acts too slowly to prove of service in the face of a great emer- gency; besides, in many patients ergot by the mouth excites nausea, and is not absorbed by the stomach ; hypodermically its action is, as a * The foregoing description is little more than a transcript of the principles enunciated in Breisky's clinical lecture, Ueber die Behandlung der puerperalen Blutungen (Volkmann's Samml. klin. Vortr., No. 14, 1871). I have found them of the utmost service to me in practice during the ten years past, and believe with Breisky that they furnish the key to successful prophylaxis and treatment. 586 THE PATHOLOGY OF LABOR. rule, rai^idly developed. Then introduce the hand into the uterus. If a full bladder interferes, draw off the urine with a catheter. The introduction of the hand into the uterus I believe to be a matter of the utmost importance. When combined with external pressure it stimulates the uterus to contract. The placenta, if ad- herent, should be detached with the tips of the fingers ; if loose within the uterine cavity, it should be withdrawn slowly, taking care to re- move the membranes entire. Bits of placenta or strips of membrane should be carefully scraped from the uterus, remembering that this is most easily effected during the contraction of the organ. Even if the placenta and membranes are expelled apparently entire, it is still de- sirable to pass the hand into the uterus to clear out clots, and to make sure that no part of the ovum has been left behind. Once I lost a hospital patient by neglecting this rule. The hemorrhage was checked by compression, and upon careful inspection of the placenta and mem- branes I convinced myself that everything had come away. The pa- tient died on the eighth day, of se^jticaemia. The autopsy revealed the presence of a small placenta siiccenturiata, of the existence of which, aside from the haemorrhage, there had not been the slightest indication. So soon as the uterus has been emptied of everything capable of preventing contraction and retraction from taking place, withdraw the Fig. 234.— Bimanual compression of uterus. (Breisky.) hand into the vagina, and, with the index and middle fingers in the posterior cul-de-sac, press the cervix forward toward the body of the uterus. With the external hand grasp the uterus through the abdomi- nal walls, compress it firmly and push it downward toward the pelvis and forward against the pubic bone. By this manoeuvre the cervix is closed, the uterine walls are brought into contact with one another, and con- POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA. 587 tractions are stimulated by the direct irritation of the large cervical ganglion and by the kneading of the fundus. Breisky states that in many cases it is j^ossible to combine compression of the aorta with the foregoing maniijulation. If bimanual compression fails to speedily secure contractions, with- out removing the internal hand, pieces of ice may be slipped into the vagina,. and thence pushed upward into the uterine cavity. With rare exceptions the uterus responds at once to the stimulus of cold applied to its inner surface. Should it not do so, however, the bed-pan should be placed under the hips, and boiled water of about 112" Fahr. should be injected into the uterus, care being taken to expel previously all air from the tube of the syringe. The injection should be made slowly and without force, allowing the fluid to escape joari passu with its introduction. The most important factor in the arrest of haemorrhage unques- tionably consists in acting promjitly upon the first signal of danger. If through lack of preparation profuse haemorrhage should occur, the overcoming of the resulting atony may tax to the utmost the re- sources of the attendant. As an effective remedy against this condi- tion the per-salts of iron added to the intra-uterine douche still enjoys professional favor. It is, however, many years since I have found it necessary to resort to their use. This I consider fortunate, for, though there is abundant testimony as to the efficacy of the per-salts of iron in post-pa rfum haemorrhage, the arrest of the flow appears, in some cases at least, to have been achieved at too dear a price. Barnes refers the haemostatic effect of the iron — 1. To its direct action in coagulating the blood in the mouths of the vessels ; 3. To its action as a powerful astringent on the inner membrane of the uterus, whereby the surface becomes corrugated and the mouths of the vessels are coustringed ; 3. To the fact that it often provokes some amount of contractile action of the muscular wall. Trask, in recommending the substitution of tinct- ure of iodine for the solution of the perchloride of iron, maintains that it is the third mode of action that should be placed first in the order of importance. This corresponds with my own experience. In two cases Avhere Monsel's solution was used the uterus contracted promptly, and the injection was followed by no disturbing effects. In the third the uterus remained large and flaccid, notwithstanding the haemorrhage was arrested. For two days the patient did well; on the third the lochia became excessively offensive, the respirations stertorous, and the pupils dilated ; general paralysis ensued, and death followed within twenty-four hours of the attack. Although no autopsy was made, it was clear to me at the time that the coagulation had followed the ves- sels to the substance of the uterus, and that the fatal result was due to the absorption of septic material by the large, soft thrombi, which, by their disintegration, became the means of conveying infection to 588 THE PATHOLOGY OF LABOR. the remoter portions of the organism. Barnes formerly used the per^ chloride of iron after preliminary removal of the clots, in the propor- tion of one of iron to three of water. Most German authorities rec- ommend the iron in a much more dilated form, and using it in no fixed proportion, but simply to pour the iron, following Seyfert's pre- scription, into the water until the latter assumes a deep wine-color. In his later writings Barnes seems to regard a mixture of one part of per- chloride to ten or twelve of watBr as adequate. Wallace * praises vinegar as a certain and safe remedy for post-jxtr- tum haemorrhage : " I pour a few tablespoonfuls into a vessel," he says, " dip into it some clean rag or a clean pocket-handkerchief. I then carry the saturated rag with my hand into the cavity of the ute- rus, and squeeze it ; the effect of the vinegar flowing over the sides of the cavity of the uterus and the vagina is magical. The relaxed and flabby uterine muscle instantly responds. The organ assumes what I will term its gizzard-like feel, shrinking down upon and compressing the operating hand, and in the vast majority of cases the ha?morrhage ceases instantly. Should one aj^plication fail to secure a sufficient con- traction, the rag can be withdrawn, and a second or even a third can be made, until the uterus shall contract sufficiently to stop the flow of blood." Probably the farad aic current is a most efficient agent in securing contractions of the uterus, but, unlike vinegar and hot water, a bat- tery is rarely on hand when needed. An olive-shaped bulb electrode should be introduced into the uterus, and the other pole, a flat disk, pressed upon the fundus ; or both poles may be applied directly over the uterus through the abdominal walls. I have in a number of instances seen Dr. I. E. Taylor succeed in instantaneously causing the uterus to contract by slapjiing the lower part of the abdomen smartly with a wetted towel. Compression of the aorta through the abdominal walls is capable of rendering temporary service. The method has been objected to on theoretical grounds : first, because the compression is brought to bear equally upon the vena cava as upon the aorta ; and, second, because the pressure does not cut off the blood which goes to the uterus through tlie aortic uterine arteries. As a clinical fact, however, it is indisputable that the pressure does, temporarily at least, check the hasmorrhage, a result attributed by Frankenhaeuser to the simulta- neous stimulation of the aortic uterine plexus, as that portion of the sympathetic nerve is termed which overlies the large vessels of the trunk situated in the lumbar region. The application of ice to the abdomen, or allowing a stream of cold water to fall from a height upon the hypogastrium, however efficacious they may prove as means of arresting hemorrhage, are open to the * Trans. Am. Gynaecol. Soc, vol. iii. POST-PARTUM HEMORRHAGE AXD RETAINED PLACENTA. 589 grave objection that they add to ah*eady existing shock and to the prostration produced by the loss of blood. Methods of securing Uterine Eetraction. — Uterine contractions afford only a temporary safeguard against hemorrhage. It is uterine retraction that prevents recurrence. At first the hand furnishes the most available means of exercising external compression. It likewise possesses the advantage of being an intelligent instrument, capable of conveying to the accoucheur instant warning of any tendency to relax- ation. But, even after retraction is secured, its maintenance should not be left to chance. Before leaving his patient, the physician should provide some means of subjecting the uterus to sustained and equable pressure. The usual method consists in surrounding the anteverted organ with folded napkins or rolled stockings, and then applying a bandage tightly to the abdomen to keep them in position. Unless skillfully executed, this method accomplishes little more than to dis- locate the uterus laterally. I have been in the habit of using a round bag of rubber covered with brown muslin, which I i:)artial]y fill with cold water, and apply over the uterus. The dry cold is of value as a means of exciting contraction, while the hydrostatic pressure is evenly distributed over the fundus of the uterus, and helps to fix it in the median line. A reliable compress may be improvised in any house- hold by partially filling a sack with moistened sand or common salt. More recently Diihrsseu * has advocated the packing of the uterine cavity with iodoform gauze. The method he pursues is as follows : When the uterus does not respond to kneading and an ergotin injection, he first, with the patient placed crosswise in bed, washes out the vagina and uterus with a three-per-cent solution of carbolic acid, then passes the fingers into the uterus to make sure that it is empty, and finally, with the cervix drawn to the vulva with volsella forceps, or under the guid- ance of two fingers passed to the cervix, a strijD of iodoform gauze is pushed by means of uterine forceps to the fundus and cavity of the uterus until the latter is completely filled. The result is said to be the immediate arrest of hemorrhage due to the intra-uterine comj^ression, and the contraction of the uterine muscle. Dr. Polk has tried the method in the Bellevue Hospital, and has been favorably impressed with its efficacy. Diihrssen advises that the packing be extended from the uterus to the vagina to control hemorrhages due to lacera- tions, but in tears of the cervix as well as in those about the vulva, the practitioner will find the suture the safest, the simplest, and the most certain haemostatic. Treatment of Anaemia.— In consequence of excessive loss of blood, the surface of the body becomes blanched, cold, and bedewed with clammy perspiration ; a feeling of muscular prostration is experienced, * DuHRSSEX, Ueber die Behandlung der Blutungen post-partum, Volkmann'sche Sammhing, No. C-IT. 590 THE PATHOLOGY OF LABOR. with distress in the prrecordial region ; thirst follows the rapid absorp- tion of serum from the parenchymatous organs to make good the loss of fluid in the blood-vessels ; the pulse becomes small and frequent, the respiration rapid, and air-hunger is developed as the result of the deficient amount of oxygen carried by the attenuated blood-stream to the tissues and the medulla oblongata. AVith these general symptoms are associated special ones due to disturbances of the nerve-centers, as restless movements from side to side, yawning, vomiting, perversions of the special senses, fainting, and convulsions. Now, it is to these latter symptoms, indicative of intense cerebral anaemia, and directly imperiling the life of the patient, that treatment requires to be especially addressed. The pillows should be withdrawn from the head, the foot of the bed should be raised, hot bottles should be placed to the extremities, and warm cloths to the head ; if syncope occurs, the abdominal aorta should be compressed to reserve the entire blood-mass for the upper portion of the trunk and the brain ; cerebral congestion should be promoted by opiates (thirty drops of laudanum by the mouth, or ten minims of Magendie's solution hypodermically in- jected), and the flagging heart should be stimulated by hypodermic injections of sulphuric ether, brandy, or whisky. The syringe should be filled with the agent chosen, and the injection should be made deep into the subcutaneous cellular tissue on the outer ])art of the thigh. The effect upon the circulation is almost instantly manifested. Ex- cept in cases whicli have passed beyond all possiliility of recovery, the pulse reappears at the wrist, often, however, to fade away again in a few minutes. The stimulant injections in many cases require to- be re- peated a number of times before the circulation becomes re-established. So long, however, as there is a perceptible response to the stimulus, tlie case is never to be regarded as hopeless. Dr. Gaspar Griswold has employed successfully in a number of cases, where the heart had apparently beat for the last time, intra- venous injections of ammonia, using for the purpose a five-per-cent solution (the officinal solution diluted with equal parts of water), and injecting with a hypodermic syringe from fifteen drops to a half- drachm into one of the superficial veins of the forearm. In the collapse resulting from excessive hemorrhage, the restoration of blood to the circulation by transfusion is theoretically the rational mode of treatment. In practice, however, the difficulties of the tech- niqiie, the hesitation of bystanders to furnish the required blood, com- bined with the somewhat unsatisfactory outcome of transfusion experi- ments, are all obstacles to its employment. More favorable results have, however, been obtained by substituting weak solutions of common salt for blood in cases where transfusion has been'^ndicated. Although -the saline solution can not replace blood, it has been proved to be a harmless agent, and capable of performing a useful part by so far restor- POST-PARTUM HAEMORRHAGE AND RETAINED PLACENTA. 59 1 ing the meclianicul conditions of circulation as to furnish a basis for analeptic treatment. The transfusion apparatus needed is of the sim- plest character, viz. : A glass funnel, a piece of rubber tubing eighteen inches in length, and a canula of glass or metal for introduction into the vein selected. The strength of the solution employed should not exceed five to six grains to the pint (0-6 per cent to 0-75 per cent). Before ojierating the instruments, the utensils, and the solution should be thoroughly sterilized. The temperature of the solution should be from 100°-103°. The amount injected varies from a pint to a quart. The transfusion should take place slowly, under a pressure of from ten to eighteen inches. The ordinary time required is from fifteen to thirty minutes. When the process is ended a double ligature should be applied to the vein, and the wound should be covered with an anti- septic dressing.* After the heart's action has once been established, the efforts of the physician should next be directed to the filling of the emptied vessels and the restoration of the arterial tension. With the restoration of the cardiac pulsations, the absorption from the stomach is very active and rapid. To avoid vomiting, however, it is necessary that fluids adminis- tered by the mouth should be given in small quantities and at brief intervals. I usually begin Avith either hot strong tea, without milk, or with brandy-and-water (1 : 2), at first a teaspoonful at a time, repeating the quantity every minute, then giving a tablespoonf ul of any warm liquid every five minutes, carefully testing the capacity of the stomach to dispose of its contents, withholding everything with the first premo- nition of nausea, until milk, broths, tea, gruel, and the like are found to be tolerated in ordinary quantities. Fluid nourishment should be continued hourly, with ice and water in the intervals, according to the thirst experienced, until the radial pulse is restored to its normal full- ness. For the successful management of these cases it is necessary that the physician assume the entire charge. It is not possible to give direc- tions to a nurse which may not at any moment require modification. In cases of excessive loss of blood a tourniquet to each femoral ar- tery, a roller bandage, or, better still, an Esmarch bandage applied the length of the lower extremities, may be temporarily employed with a view to saving the limited amount of blood in the circulation for the important organs of the trunk and for the nerve-centers. Where the pulse is extremely rapid, the subcutaneous injection of one fiftieth of a grain of digitalin is reported to act favorably by caus- ing contractions of the arterioles and of the uterus. O^nates should be administered from time to time during convales- cence, the frequency and quantity depending upon the intensity of the headache which acute anaemia induces. * Otto Leichtexsterx, Ueher Koohsalz infusion bci Verblutungen, Yolk- maun'sche, Sammhing, No. 25, Xeue Fol^c, p. 253. 592 THE PATHOLOGY OF LABOR. The Puerperal Haemorrhages.— Ha?morrliages occurring after the first day following confinement are the result either of the separation of the thrombi from the placental site or of a congested condition of the endometrium. Before the consolidation of the thrombi is completed, the mouths of single vessels may be opened by any sudden increase of pressure in the uterine vessels. A relaxed state of the uterus, obstacles to retrac- tion, fecal accumulations, and malpositions of the uterus predispose to the occurrence of haemorrhage. Common causes of late haemorrhages are sitting up or leaving the bed at too early a period, exertions in car- ing for the infant, and straining at stool. In the case of a small, thin woman who flowed profusely in the second week, I found the uterus crowded backward and downward to the pelvic floor by the compress, which had been too tightly bandaged upon tlie abdomen by the indis- creet zeal of the nurse. Where portions of the ovum have been allowed to remain behind in the uterus, they may lead to the formation of fibrinous polypi, which, as in the non-puerperal uterus, occasion a vascular condition of the mucous membrane, and become the cause of protracted bleeding. The treatment of late haemorrhages consists in rest in the horizon- tal position, in carefully regulated diet, in emptying both bladder and rectum, in the correction of displacements, and in the use of hot vagi- nal injections. In excessive anteve'rsion a compress above the pubes is indicated ; in retro-displacements, lifting the uterus into position, maintaining it in place by a suitable pessary, is often at once followed by relief. If other causes can be excluded the uterine cavity should be explored, and retained bodies, if found present, should be removed. When the cervix is patulous this can be accomplished by the finger ; if the cervix is partially closed, or if inflammation be present, the wire curette, can be used, as after abortion, without preliminary dilatation. In curetting the uterus the operator should be mindful of the delicacy of the newly forming mucous membrane, and should feel carefully for the offending bodies. If the bleeding continues the uterine cavity may be tamponed with iodoform gauzeN- Retaixed Placenta. Retained placenta is so frequently a cause of hindered uterine re- traction that a few words concerning the etiology and treatment of the condition form an appropriate appendix to the discussion of post- partum haemorrhage. Cases of so-called placental retention are often simply the result of injudicious management. Thus, they may be caused by pulling in such a way upon the cord as to draw the center of the placenta into the cervix, so that, without allowing air to pass by the placenta to the uterine cavity, extraction is rendered impossible; or, Avhen Crede's POST-PARTUM HEMORRHAGE AND RETAINED PLACENTA. 593 method is practiced, the operator may, by pressing the fundus forward against the pubes instead of downward in the axis of the pelvis, pro- duce an acute anteflexion, with stenosis of the lower uterine canal. True retentian may be due to the^ large size of the placenta or to pathological adhesions, either of the placenta itself or of the chorion. An adhe rent_j )lacenta is of rare occurrence, and can usually be traced to a bygone endometritis. Separation normally takes place in the areolar layer. If the glandular walls which constitute the septa of the areola consist of tough intercellular substance instead of soft tissue abundantly supplied with cells, the separation does not take place, and the placenta remains adherent. The thick bands which have to be severed in removing the placenta are in general the straight trunks of the villi, which run from the chorion to the serotina, the separation taking place not in the decidual but in the fetal layer. In placentitis the bands consist of thickened decidual tissue extending between the cotyledons. In either case the serotina is left nearly or quite entire; in some instances, owing to their firm attachment, whole lobules may be left behind. Adhesions of the chorion may be due to thickening of the septa in the areolar layer ; to defective involution of the cell-layer of the decidua, thickened portions of which in consequence remain attached to the separated chorion ; to secondary adhesions from consolidated masses of fibrine, the remains of apoplectic effusions into the decidua ; and, perhaps, to excessive development of villi upon portions of the smooth chorion, from which proceed thick bands which are firmly united to the decidua (Spiegelberg). Adhesions of the chorion inter- fere with the separation of the placenta only when situated high up or around the placental border. The Artificial Separation of the Placenta.— AVhenever compression of the uterus proves unavailing to procure the expulsion of the pla- centa, the operator should seek to aid the delivery by the resources of art. To leave the placenta within the uterus not only exposes the patient to the risks of haemorrhage, but to the even greater danger of decomposition and of septic poisoning. A digital examination will indicate the proper course to be pursued. If the placenta be found covering the os, a finger should be introduced to bring down a placen- tal border. If no adhesions exist, moderate tractions upon the cord will then suffice to deliver the placenta. Spiegelberg recommends using the vaginal finger as a pulley to cause the tractions upon the placenta to be made in a vertical direction. If tractions upon the cord are insufficient, or if the cord begins to tear, the outer hand should make counter-pressure upon the fundus, while the fingers of the vaginal hand are passed upward into the uter- ine cavity. At first a point should be selected where the placenta is already partially detached, and the fingers should be employed to roll 38 594 THE PATHOLOGY OP LABOR. the placenta away from the uterine wall. If the attachment of the placenta is firm, the fingers should be extended with the back of the hand to the uterus, and the separation attempted by a side-to-side movement, as in cutting the leaves of a book. Contractions are here of great service, as they both facilitate the separation and serve to ren- der distinct the border-line between the placenta and the uterus. Hildebrandt advises following the cord upward and separating the placenta with the hand covered by the membranes, as a means of avoiding the dangers of infection and of injuring the internal uterine surface. Spiegelberg says that in his experience this method has suc- ceeded only where the placental attachment was loose and the separa- tion easy. Bands should be divided by pressing them between the thumb-nail and the index-finger. When the placenta is situated upon the anterior wall, the patient should be placed upon the side. When the placenta is everywhere adherent, a thickened border should be chosen as the point for commencing the detachment. In a very thin, diffused pla- centa, it has been proposed by Ilohl to inject the vessels through the umbilical vein. The operati9n of separating the placenta should never be per- formed hurriedly. Every pains should be taken to avoid injuring the uterine surface, and as little jjlacental tissue as j)0ssible should be left behind. When the detachment of the placenta is completed, it should be grasped from above in the full hand, and its expulsion should be effected by external pressure. If portions of the membranes are torn away during delivery, they should be sought for and carefully re- moved. In every case of artificial placental delivery the cavity of the uterus should subsequently be thoroughly irrigated with warm carbolized water. CHAPTER XXXII.

Situation.— Varieties.— Frequency.— Causes of haemorrhage.— Clinical features.— Prognosis. — Diagnosis.— Treatment.— Accidental haemorrhage.- Inversion of the uterus. Situation.— Normally the placenta, as we know, is situated at the fundus and upon the side walls of the uterus. It is said to be prcBvia when it occupies that portion of the uterus which is subject to disten- tion during labor, or, in other words, to the spherical surface of the PLACENTA PREVIA. 595 lower portion of the uterus. Its clinical importance is proportioned to the extent of the placental segment which overlaps the os internum. Hence it is customary to distinguish — Varieties. — 1. Placenta prcBvia centralis, where, after the dilata- tion of the OS internum has become complete, the placenta only can be felt. 2. Placenta jircevia partialis, where, with dilated os, there is recog- nizable a portion of the membranes, as well as a segment of the pla- centa. 3. Placenta prcBvia lateralis, or marginalis, where the placental border stretches down to, but not beyond, the margin of the inner cer- vical ring. Observations which tend to prove the attachment of the placenta in part to the cervical mucous membrane are unquestionably erroneous. The fact, first stubbornly insisted upon by Professor I. E. Taylor, has, at least among jDhysiologists, passed beyond the realm of dispute. Kuhn,* who investigated the subject in conjunction with Carl Braun, found that in no case was the placental portion which occupied the cervical canal adherent to the canal-walls, but that in all post-morteni examinations the remains of the jilacenta prgevia materna ended by a sharp border-line at the os internum. An exact central implantation of the placenta is extremely rare, though its occurrence is not impossible. Usually in the so-called cen- tral form not more than one sixth to one fourth of the placental sur- face overlaps the os internum. The smaller segment is oftener found upon the left side (37 :56, statistics of L. Muller).f Owing to the deficient thickness of the decidua in the vicinity of the internal os, the placental villi grow with less profusion at that point, while by way of compensation in more favored localities they attain to an excessive development. The placenta thus assumes a char- acteristic uneven appearance. If the atrophic conditions exist over a wide extent, the surface of the placenta is, as a rule, correspondingly increased. Another peculiarity not devoid of practical interest is the frequency w^th which the placenta is found adherent to the uterine walls. Of 142 cases, L. M tiller showed that in 56 adhesions existed. The inser- tion of the cord into the placenta is usually eccentric, often marginal, and sometimes velamentous. As a consequence, prolapsed funis is a common accompaniment of the anomaly. Fortunately, placenta praevia is of rare occurrence. Miiller, by add- ing together the statistics of various investigators, found reported 813 * Braun, Lehrbuch der ges.

Sci., 1856, vol. viii) and of most of the later writers, up to date of publication. 596 THE PATHOLOGY OF LABOR. instances in 876,432 births, or not quite one case in a thousand. Since the opening of the Emergency Hospital in this city there have been between 1,500 and 1,600 women confined in that institution. So far there has been no case of placenta praevia. Lomer,* on the other hand, estimates the minimum frequency in Berlin at one in 723 births. Etiology. — The causes are unknown. The proportion of multiparte to primipara3 is very large (6 : l).f Placenta prsevia is most frequent in women who have borne children with great rapidity, and in preg- nancies shortly following abortions, conditions which favor relaxation of the uterine walls, dilatation of the cavity, and defective development of the decidua. Miiller advances the theory that the descent of the ovum is effected by contractions of the uterus soon after conception. Such expulsive pains naturally lead to abortion. In certain cases, how- ever, where the reflexa is absent, we have seen that the ovum may be forced downward into the cervical canal, and lingering there may give rise to " cervical pregnancy." Placenta prajvia Miiller believes to be due to an abortion begun at an early period, but arrested at the lower uterine segment to which the villi attach themselves, and enable the rescued ovum to continue its development. Ingleby relates two curi- ous cases where the orifices of the Fallojjian tubes opened near the os internum, in one of which placenta praevia occurred three times, and in the other ten times. Clinical Features. — The chief clinical importance of placenta prae- via results from the mode of its detachment during labor. In normal positions the separation of the placenta is elfected by virtue of the uterine contractions after the foetus has for the most part been ex- pelled. In placenta praevia the separation is due to the stretching to which the lower uterine zone is subjected in its conversion from a half- sphere to a cylindrical canal, to permit the passage of the child. The extent of unavoidable separation in advance of delivery is consequently measured by the dimensions of the child's head, the largest circumfer- ence of which is estimated as equivalent to a circle with a diameter of four and a half inches. According to Duncan, the plane at which spontaneous detachment ceases is reached at a distance of two and a half inches by following the curve of the lower segment, and of one inch and a half if measured in the direction of the uterine axis. Whereas, in normal labor, the contractions of the uterus which determine pla- cental separation close at the same time the orifices of the torn vessels, tlie stretching of the lower segment in placenta praevia leaves tlie mouths of the sinuses gaping, from which the blood pours until the * Lomer, Combined Turning in the Treatment of Placenta Praevia, Am.

PLACENTA PR.EVIA. 597 stream is arrested either by art or by the supervention of syncope. Ag the haemorrhage in such cases is the natural sequence of cervical dila- tation, its occurrence during labor was termed by Rigby " unavoida- ble " in contradistinction to hajmorrhages from detachment of the pla- centa when situated near the fundus, where the separation is attributable to " accidental " causes. The hemorrhages of placenta pra3- via are not, however, limited to the parturient period. Indeed, there is no time in pregnancy when they may not occur. When we consider that every jar of the body affects the lower seg- ment with more force than the fundus, and that the thinned walls of the utero- placental vessels are subject to increased pressure in placental presentations, it becomes evident that a very slight occa- sion is sufficient to produce rupture and haemorrhage. Thus placenta praevia is a common cause of the pseudo-menstru- ation of pregnancy; it creates a pre- disposition to abortion, and, later in gestation, to premature labor, the haem- orrhages being due probably in the first instance to accidental causes and not to labor-pains. Not every case of haemorrhage is, however, fol- lowed by labor. Indeed, in many instances thrombi form in the open vessels, the bleeding becomes arrested, and pregnancy goes on for a time undisturbed. The tables of Miiller show that in complete pla- centa previa the first hsemorrhage occurs with the greatest frequency between the twenty-eighth and thirty-sixth weeks, while in the in- complete form it takes place most commonly after the thirty-second week. In placenta praevia lateralis, haemorrhages are sometimes absent up to the time of labor. Cases of pregnancy, and in part of labor, without hemorrhage have been observed where the death of the foetus has been followed by atrophic changes in the placenta. The recur- rence of haemorrhage is oftentimes prevented by secondary shrinkage of the placenta, due to pressure from the effused blood or to throm- bosis of the vessels which supply the implicated cotyledons. The hemorrhages of placenta previa are usually sudden without premonitory warnings, without pain, often without any apparent occa- sion, sometimes occurring at the time of urination, sometimes during sleep. The quantity of blood lost in a single hemorrhage depends upon the extent of the placental separation. The first outpouring may Fig. 225.— Diagram shoving the unavoid- able placental separation as a conse- quence of cervical dilatation. gQg THE PATHOLOGY OP LABOR. lead to intense anemia, and if repeated at a short iiiterval may cause death. It is estimated that from one to three pounds of blood may be lost in a single attack, and from four to five pounds in the course of labor (Miiller). As a rule, however, the haemorrhages of pregnancy are at first moderate in character, increasing in violence with each rep- etition. A very formidable variety is the so-called '^ stillicidium," where the blood issues drop by drop for days and even weeks in suc- cession. The most violent hemorrhages occur generally in the earlier part of the first stage of labor. As a rule, the extent of the haemor- rhage is proportioned to the area of the placental segment attached to the uterine surface subject to distention. The hemorrhage generally ceases when the separation of the cotyledons is completed and, after the rupture of the membranes, the pressure of the presenting part is brought to bear upon the bleeding surface. During the height of the pains, too, the haemorrhage is for the moment arrested (Spiegel- berg).* The number of abnormal presentations in placenta praevia is very large. Thus, in Miiller's statistics, in 1,148 cases there were 272 trans- verse and 107 breech presentations. The frequency of the anomalies is partly attributable to the large proportion of premature labors, and partly to the width and lax condition of tlie lower segment, and the consequent want of stability in the foetus. During the first stage of labor the pains are apt to be feeble and the dilatation tardy. The causes of inertia are to be found in the thin- ning of the muscular structures in the lower segment from the enor- mous development of the utero-placental vessels ; in the attachment of the placenta over the os, which mechjinically hinders dilatation ; and in the fact that the ovum does not press directly upon the sensitive nerves of the cervix. Secondary weakness often follows the continued losses of blood and the prolongation of the first stage. "When the ob- stacle afforded by the placenta to dilatation has been overcome, and, consecutive to rupture of the membranes, the uterus retracts, in many cases the scene speedily changes, and, in place of ineffective contrac- tions, normal and often powerful pains develop. As a rule, quite early in labor the cervix is found soft and dilat- able ; but to this rule there are numerous exceptions. Strictures and rigidity Miiller computes to exist in about twelve per cent of the cases. Where the loss of blood in labor is continuous the woman grows restless and complains of headache and vertigo ; the respirations become short, interrupted, and sighing, and the pulse small, weak, and thready. Toward the close unconsciousness develops, the brow is bedewed with * This view was first advanced by Fountain in the Am. Jour, of the Med. Sci. It has since been advocated by Duncan, Jiidell. Frankel, Spiegelberg, and others. Miiller and Kuhn, however, dispute it, as justified neither by theory nor by ob- servation. PLACENTA PR.EVIA. 599 cold, clammy perspiration, and finally convulsions usher in the fatal termination. Even after labor is over the danger is not ended. Post-partum hem- orrhage may result from atony of the placental surface of the uterus, or, after good contractions have been apparently secured, sudden re- laxation may follow, and the blood pour out in a torrent, so that the patient becomes a corpse before assistance can be rendered. Again, in childbed the imperfect contraction of the uterus at times allows the lochia to form a stagnant pool at the fundus, whence an ichorous dis- charge flows constantly downward over the thinned walls and open mouths of the vessels at the placental wound. The feeble circulation predisposes to the formation of thrombi, which, when poisoned and disintegrated, are conveyed into the general circulation and give rise to the dreaded symptoms of pyemia. Mtiller found in two hundred and seventy-three of his cases specific information given regarding the puerperal state. " Puerperal fever " was recorded of seventy-nine pa- tients, with fifty-four deaths. Prognosis.— The prognosis of placenta praevia is necessarily ex- tremely unfavorable. As many as one mother in four dies during or shortly after delivery. Including deaths from puerperal jirocesses, Mtiller estimates the total mortality at not less than from thirty-six to forty per cent. Nearly two out of three of the children are born dead. More than one half of those born living die within the first ten days. In general terms it may be stated that the prognosis is the more seri- ous the earlier the hemorrhages begin in pregnancy, the more profuse the flow, and the shorter the intervals between the attacks. During labor favorable conditions are a vertex presentation, good pains, rapid dilatation, and an unbroken constitution. The maternal mortality is twice as great in placenta previa centralis as in placenta previa later- alis. In the city there is the special danger of infection ; in the coun- try, of delay in obtaining medical assistance. Finally, it is impossible to analyze the statistics of j^lacenta previa without coming to the con- clusion that the result depends in a large measure upon the personal qualities of the physician. A self-possessed man, cool, resolute, with clear ideas of the anatomical conditions to be dealt with, will, if sum- moned in season, apjjarently dejjrive even placenta previa of a good share of its terrors. Diagnosis. — There are no signs by which placenta previa can be recognized in the first half of pregnancy. It may occasion abortion, which is then characterized by the absence of pain, both previous to the hemorrhage and during the period of expulsion. As a rule, the ovum is expelled entire without rupture of the membranes. In the second half of pregnancy, a hemorrhage occurring suddenly, without ostensible cause and without wariiing, shoiild always be regarded with suspicion. Upon digital exploration in placenta previa the vaginal gQQ THE PATHOLOGY OF LABOR. fornix is found soft and boggy, and occasionally thicker upon the one side than upon the other, where the placental presentation is incom- plete ; ballottement is obscure ; the cervix is long, wide, and soft, and contains at times vessels which pulsate distinctly ; the cervical canal permits the passage of the finger to the os internum, which at first offers resistance, but yields to gentle force. The diagnosis is rendered positive only in cases where the lower surface of the placenta is actu- ally felt through the cervix, its rough, spongy, granular texture suf- ficiently distinguishing it from clots and other possible sources of de- ception. Treatment. — The history of placenta praevia brings into prominence the central point to be kept steadily in view in practice, that there is no safety for the mother so long as pregnancy continues. In a very large proportion of cases, accidental haemorrhage occurring in the first half of pregnancy leads to abortion, the management of which does not differ from that cf abortions which take place in normal attachments of the placenta. Of the one hundred and twenty-eight deaths from placenta praevia collected by Miiller, not one occurred previous to the seventh month. In the latter half of pregnancy, hemorrhage likewise leads to premature expulsion of the ovum with such frequency that it is reckoned that only one third of all cases reach the end of gestation. Most authorities advise, in the presence of the haemorrhages of ad- vanced pregnancy, that the physician maintain an attitude of expect- ancy, postponing active interference, except in cases where the loss of blood assumes alarming proportions, until the spontaneous advent of labor. This policy is recommended partly in the interest of the child, and partly because of the tendency in premature labor to rigidity of the cervix, a complication which always in placenta praevia enhances the risks of delivery. The wisdom of delay is, however, open to seri- ous question. The fatality of placenta prajvia is due not so much to the impotence of obstetrical art as to the losses of blood which occur suddenly in the absence of professional assistance. The first haemor- rhage, which serves as a warning as to the patient's condition, is fortu- nately in most instances slight. With each recurrence, however, the flow becomes more profuse. If the haemorrhages begin before the child is viable, the chances of saving its life are in any event too small to offset for a moment the welfare of the mother. Haemorrhages occur- ring as early as the seventh month are, as a rule, the result of complete placental presentation. To trifle witli such cases is the best way to maintain the present mournful statistics. After the thirty-second week it is safe to say that the child's life is less imperiled by the in- duction of premature labor than by exposing it to the dangers of con- tinued gestation. On theoretical grounds, therefore, the induction of premature labor is to be regarded as obligatory so soon as the diagnosis of placenta PLACENTA PREVIA. 601 jiraevia is established, or at least with the occurrence of the first haemor- rhage. The practical results of this measure in the hands of its advo- cates * plead still more effectively in its behalf. Thus, Dr. Gaillard Thomas f reports eleven cases, with but two deaths, one resulting from post-partum hoemorrhage coming on several hours after delivery, and one from puerperal fever. Hecker X lost three cases in forty, Hoff- mann two cases in thirty, and Spiegelberg four cases in seventy-four early deliveries.* More recently Murphy || has reported fifteen cases without a single death. In this connection I can not help quoting the following impressive remarks of Dr. Barnes : " If the pregnancy have advanced beyond the seventh month it will, as a general rule, I think, be wise to proceed to delivery, for the next htemorrhage may be fatal ; we can not tell the time or extent of its occurrence, and, when it oc- curs, all, perhaps, that we shall have the opportunity of doing will be to regret that we did not act when we had the chance." In the management of placenta praevia it is very desirable that the practitioner should have a perfectly clear idea of the nature of the task he has to perform. The birth of the child can not take place without preliminary expansion of the cervix. The cervix can not ex- pand without detachment of the placenta. The principal objective point of treatment, therefore, is the haemorrhage which occurs during the stage of dilatation. Plans for restricting the flow within narrow limits have been proposed without number by masters of the obstetric art. The best plans are those which at the same time contribute to shorten labor. The choice must be determined by conditions which necessarily vary in different cases. The physician has at the outset to particularly inform himself as to whether labor has begun or remains to be inaugurated, as to whether the placenta praevia is complete or in- complete, as to whether the presentation is normal and the pains are good, as to whether the membranes have ruptured or are intact, and as to the length and dilatability of the cervix. If the cervix is long, narrow, and rigid, and the membranes are entire, the vaginal tampon should be lesorted to as a temporary expe- dient. The tampon strengthens the pains, and, by the compression it exerts, causes coagulation of the blood which escapes from the uter- ine vessels. Professor I. E. Taylor advises packing the vagina with a surgical bandage, leaving one end outside the vulva, by means of which it can be withdrawn without difficulty. Braun, after many years' ex- * Premature labor in profuse or continuous haemorrhage has received the in- dorsement in this country of Thomas, Taylor, Parvin, Pallen, and Taber Johnson. t Trans, of the N.

Thus, Spiegelberg's complete death-rate reached sixteen per cent. II Murphy, Brit. Med.

I use cotton, made into disks, and dampened in a two-per-cent sokition of carbolic acid, crowding it into the upper portion of the vagina with the aid of a Sims speculum. The choice does not appear to be material if due attention be jiaid to the carrying out of aseptic details. Having once introduced the tampon, the physi- cian should not leave his patient until the labor is ended. After at most four hours the tamjjon should be removed, and, after rendering the vagina thoroughly aseptic, the cervix should be examined. A second introduction of the tampon is rarely necessary, or, owing to the dangers of septic infection, expedient. So soon as the os will permit the passage of the finger, the vaginal plug should be discarded. The operator will then have to choose between one of two jjlans of action, viz., dilatation of the cervix by means of water-bags, or version by Braxton Hicks's method. If dilata- tion is decided upon, a Barnes rul^ber-bag, expanded sufficiently to render the border of the os externum tense, fulfills admirably the prin- cipal indications. It acts as an efficient tampon, it strengthens the pains, and it dilates the cervical canal. As the latter expands, a larger-sized dilator should be introduced. It is important, in order to prevent hemorrhage, to maintain the tension of the external orifice. On account of the softening which exists in the lower uterine segment as a result of placenta previa, in a large proportion of cases the cervix can be stretched with the utmost facility. If no ui'gent symptoms call for immediate interference, it is desirable to render the dilatation complete. It is not, however, always necessary. Indeed, Barnes, Taylor, Spiegelberg, and Braun advise to proceed boldly with the de- livery so soon as the os externum has expanded to the size of a half- dollar, as by that time the expansion of the os internum is very nearly completed, and as the soft cervical canal does not offer sufficient re- sistance to materially interfere with the extraction of the child. The distinguished success of the authorities mentioned in the field of prac- tice under consideration lends great weight to their recommendations. It is, however, more than probable that exceptional training and ex- perience count in their case for quite as much as the plans of proced- ure they individually favor. At any rate, in reviewing the statistics of Trask and Miiller it becomes evident that rigidity of the cervix is not a rare event in placenta praevia, and that the acconchemcnf force, performed with a rigid cervical canal, is perhaps, next to doing nothing, the most responsible cause of the mournful results they have placed on record. Jungbluth (Die Behandlung der placenta praevia, Volkmannsche Samm- lung, No. 3,35), advocates the use of large sponge tents, rendered aseptic by careful preparation, {inde p. 360), in placenta praevia. He claims in their favor that they cause active uterine contractions, and act as an efficient tampon, so PLACENTA PREVIA. 603 that complete dilatation of the cervix can be secured without loss of blood. He directs that the attendant shall first ascertain the direction and width of the cervix and the distance of the os externum from the placenta. He then selects a tent to correspond. With a sharp knife the tent should be cut across so that when introduced its length shall not exceed that of the canal by more than an inch. The abtruncated tent is to be seized in ovum forceps, the cut end is to be dipped for a moment in hot water, and then, under the guidance of two fingers in the vagina and with counterpressure from above, the tent is to be pushed up the canal to the placenta, and held in place for ten to fifteen minutes, by which time the expansion is sufficient to tampon the lower uterine segment. Jung- bluth claims that if at the outset the external parts, the vagina, the instru- ments, and the hands of the operator are surgically clean, the tent after its in- troduction may be left eight or ten hours in situ without the slightest risk of sepsis. Sometimes one, sometimes as many as three or four, sponge cylinders are requisite. If unfilled spaces are left, small tents should be inserted to secure a complete tamponing effect. In no case should a vaginal tampon be used. A comj^ress to the vulva will show if any leakage occurs. In that case it is an in- dication that the tents have been faultily placed. They should then be removed, and new ones should be introduced. A renewal of the tents is likewise re- quired when, as the cervix softens and dilates, the finger can be pushed at the border u])ward to the placenta. The vagina should be then washed with carbolic-acid solution (two per cent), the hands disinfected, and the sponges withdrawn by a leverage movement. In the partially expanded cervix three or four cylinders tied together should be introduced and held in place in the manner already described. A third renewal is rarely necessary. In answer to the objection that the method is troublesome, Jungbluth argues that trouble is of small consideration when life is at stake. After the cervix has been duly prepared the membranes should be ruptured, and a part of the amniotic fluid should be permitted to escape. Then, if the j^lacenta possesses a lateral or a marginal attach- ment, if the pelvis is of normal size and the pains strong and regular, and if the head present, or at least can be brought down and fixed at the pelvic brim- by external manipulations, the further progress of the case may be left to Nature. Haemorrhage will then be prevented by the pressure of the foetus in its descent through the utero-vaginal canal. At first the method of expression advocated by Kristeller is capable of rendering important service by promoting the speedy en- gagement of the child's head. Ergot, too, cautiously administered, is useful in strengthening the uterine contractions. Even if tonic con- traction follow from its employment — an unlikely event in placenta prtevia — the effect would be to close the sinuses and to furnish a fresh barrier against haemorrhage. The forceps may be applied under the same circumstances, and with the same restrictions, as in other con- ditions. Where, however, the head is movable, the patient ansemic, and hfemorrhage persistent, version, as furnishing the more rapid mode of delivery, would receive the preference. QQ^ THE PATHOLOGY OF LABOR. In cases of complete attachment of the placenta there should be no trifling with half-way measures. If the cervix is long and rigid, the vaginal tampon should be employed as a preliminary measure. When the cervical tissues have become softened, and dilatation has beo-un, the tampon should be removed. At this stage Barnes recom- mends separating at once that portion of the placenta which is attached above the inner orifice of the cervix. By so doing, " we remove an obstacle to the dilatation of the cervix, for the adherent placenta acts as an impediment." The operation is performed as follows: "Pass one or two fingers, as far as they will go, through the os uteri, the hand being passe" into the vagina if necessary; feeling the placenta, insinuate the finger between it and the uterine wall ; sweep the finger around in a circle, so as to separate the placenta as far as the finger can reach. . . . Commoi\ly some amount of retraction of the cervix takes place after this operation, and often the haemorrhage ceases." * Next put in a Barnes dilator and rapidly expand the cervix. Mean- time try and bring the breech down into the lower uterine segment by external palpation. Both Taylor and Braun have found external ver- sion easy, on account of the inert conditions of the uterine walls. When the cervix has been sufficiently stretched to admit of delivery, two fingers should be introduced, the placenta should be separated, the memlu'anes ruptured, and an extremity should be seized without passing the entire hand into the uterus. Extraction should then follow, the pressure of the foetus preventing any considerable amount of haemorrhage. Usually the right hand is chosen to seek the feet, as the placenta more frequently overlaps the left side. Often a hint is furnished by the fact that the overlapping portion of the placenta is separated to a greater extent than the main body. Many times, however, it will be necessary to change the direction of the fingers before the edge of the placenta is reached. If external version can not be effected, the opera- tor should push the hand forward into the uterus to find an extremity. The arm acts during the search as a temporary tampon. Ha?morrhage, which follows the withdrawal of the arm, will be arrested by the de- scent of the breech. The accidental rupture of the membranes before the cervix is pre- pared for artificial delivery is hardly likely to occur in cases of placenta praevia comi)leta. In cases of marginal implantation, dilatation with water-bags should be employed in such a way as to compress the open sinuses from which bleeding takes place. * Barnes, Obstetrical Operations, p. 503. The artificial separation of the placenta is unquestionably of service where it can be accomplished without dif- ficulty. Much time should not, however, be lost in fruitless efforts, nor is it de- sirable to persist if the separation can not be accomplished smoothly. Behm, Hofmeier, and Lomer all urge in such cases passing the fin<;ers directly through the placental tissue. The most alarming hsemorr"haf5~Teases when the leg is brought down. PLACENTA PREVIA. 6O5 In 1861 Braxton Hicks recommended for the treatment of placenta praevia turning the child by the two-finger method in an early stage of labor, and, after rupture of the membranes, bringing down the breech to tampon the bleeding vessels. This practice has been followed with distinguished success by Hof meier * and Behm f and in the University Hospital for AVomen, in Berlin. The cases reported from the latter institution by Lomer| were 101, operated upon by nine different assist- ants, with a total of 7 deaths. Hofmeier reported 37 cases with 1 death, and Behm 35 cases with no maternal death. Thus, in 178 cases occurring in the practice of 11 individuals, there were 8 deaths, a mor- tality of but 4-5 per cent. But Lomer had no death in 16 cases. The addition of these latter to those of Hofmeier and Behm gives in the practice of three individuals only 1 death in 93. To be sure, the life of the child is made, by this premature version, a secondary considera- tion. Hofmeier reports an infantile mortality of 67 per cent, that of Behm was 80 per cent, while in Lomer's report the fetal death-rate was only 50 per cent. However, many of the reported deaths were in non-viable children, or were cases where the death of the child occurred long prior to birth, Hofmeier advocates following up version by the slow extraction of the child. By this means he has succeeded in ending labor in the course of from half an hour to one hour and three quarters. Behm counsels awaiting the spontaneous expulsion of the child, or at least the complete dilatation of the cervix. Lomer says : " In our cases we exert gentle tractions now and then, until the cervix is completely dilated, and we then slowly increase the number and strength of the tractions." Lomer sums up the advantage of the method as follows : 1. It does away with the tampon, and the conse- quent dangers of infection. 2. It allows us to operate early. 3. It arrests haemorrhage with great certainty. 4. It gives time for the patient to rally, for the cervix to dilate, and for pains to set in. It therefore prevents post-partum hemorrhage. I have recently had occasion to test this plan in a case of placenta previa completa, and am prepared to speak most strongly in its favor, as both mother and child were saved, though I still believe that a certain amount of preliminary dilatation with Barnes's bags tends to enhance the chances of the child without endangering the life of the mother. After the birth of the child, the danger of post-j^artum hemorrhage must be kept in mind. Every preparation should be made in anticipa- tion of its occurrence. If bleeding persists after the fundus is felt to * Hofmeier. Zur Behandlung der Placenta Pnevia, Ztschr. f.

II Q^Q THE PATHOLOGY OP LABOR. be firmly contracted, a speculum should be introduced, and the open sinuses of the lower segment should be swabbed with cotton soaked in some styptic form of iron, as recommended by Engelmann (vide Post- partum Hemorrhage). Ergot should be given for several days, as the danger of late hemorrhages is specially great following placenta previa. The utmost cleanliness and the use of disinfectant vaginal douches must be insisted on during the childbed period, as the exposure of the placental wound to the lochia, which constantly flow over it, renders the patient especially liable to septic infection. HEemorrhage from Normally Implanted Placenta.— The placenta, even when implanted over the upper polar circle, the safe placental seat of Dr. Barnes, may become detached to a greater or less extent during pregnancy or labor, and may then furnish a flow of blood that either remains internal and concealed or may find its way between the decidua vera and reflexa, and thus escape into the vagina. The hemorrhages from this variety of placental separation are termed " accidental," in contradistinction to the " unavoidable " form, which is the accompaniment of placenta previa. The circumstances under which concealed hemorrhage takes place are given by Goodell * as follows : (a) When the placenta is centrally detached, and the blood accumulates in the cul-de-sac formed by the firm adhesion of its margins to the uterine wall, (b) When the pla- centa is so detached that the blood escapes into the uterine cavity behind the membranes near the fundus, {c) When membranes are ruptured near the detached placenta and the effused blood mingles with the liquor amnii. {d) When the presenting part of the foetus so accurately plugs up the maternal outlet that no existing hemorrhage can escape externally. ' The causes of internal hemorrhage, when such can be determined, are for the most part similar to those considered in connection with abortion. Thus, the circumstances leading to placental detachment Goodell found to be irregular uterine contractions, external violence, and undue exertion ; in seven the causes were purely emotional, and ten took place during sleep. It occurs more frequently in multipara and in the latter months of pregnancy. The symptoms are an alarming state of collapse, pain often excess- ive, absence or extreme feebleness of the pains of labor, marked dis- tention of the uterus, sometimes a lateral bulging of the uterine walls, a show of blood, a serous discharge, and blood in the liquor amnii. The diagnosis in the concealed form may be extremely embarrass- ing. The pain is often that of flatulent colic. The accident likewise * Goodell. On Concealed Accidental Hapmorrhage of the Gravid Uterus (Am. Jour, of Obstet., August, 1869, p. 281). This paper serves as a mine from which most subsequent writers have drawn their data. PLACENTA PRiEVIA. G07 presents many features which resemble those of ruptured uterus ; but rupture, by contrast, rarely occurs until after the escape of the waters, the presenting part then receding from the os, and the uterus dimin- ishing in size. The prognosis is very unfavorable. Goodell reports : " Out of one hundred and six tabulated cases, fifty-four mothers perished ; and out of one hundred and seven children, six alone are known to have been saved." I have had a case since his paper, where, after labor, I re- moved at least a basinful of firm clots from the uterine cavity, and yet both mother and child survived. In cases of external ha3morrhage the diagnosis is easy and the prognosis more favorable, the latter probably because the walls are less flaccid than in the concealed form. The treatment consists in the subcutaneous injections of ergot, in dilatation of the os with Barnes dilators, in rupture of the membranes, and in version. In my own case, to which I have referred, the Barnes dilator acted capitally, not only enabling me to expand the cervix, but exciting the uterus to contract vigorously. The serious symptoms set in after the membranes were ruptured, and compelled me to deliver with forceps. In another case I should certainly first dilate, and, after ruptiire of the membranes, should choose version and speedy extraction, and should avail myself of a skilled assistant, whose duty it should be to compress the uterine walls externally during the act of delivery. Inversio Uteri. — Inversion of the uterus is a rare occurrence. Braun states that, of two hundred and fifty thousand births in the clinics respectively under the charge of 8paetli and himself, not a sin- gle complete inversion has come to their notice. There was one case in one hundred and ninety thousand confinements at the Eotunda Hospital in Dublin. The production of inversion is favored by a large, relaxed uterus, the result of overdistention, of rapid delivery, or of haemorrhage. The immediate cause may be either pressure exerted from above or traction Irom below. The first may^jproceed from straining efforts, especially in a sitting or kneeling position, or from attempts at pla- cental expulsion before u^erme contractions have been secured ; the second may proceed from 'a_short or coiled cord during expulsion, from tractions upon the cord after the child is born, or simply from the weight of the placenta. HennTg^*^ concludes that the attachment of the placenta to the fundus, instead of a more lateral implantation, is an active cause of the accident. Inversion may be partial or complete. In the former the fundus })resents a saucer- or cup-like depression ; in the latter the entire * Hennig. Ueber die Ursachen der spontanen Inversio Uteri, Arch. f. Gynaek., Bd. vii, p. 491. 608 THE PATHOLOGY OF LABOR. fundus descends into the vagina ; in extreme instances the cervix may be inverted to tlie vaginal attachment. Dr. I. E. Taylor maintains a mechanism for a certain number of cases, which consists in a rolling out of the cervix, with gradual implication of the body and fundus. The symptoms of inversion are shock and haemorrhage. The shock is evidenced by the small pulse, coldextremities, vomiting, and sunken features, and is due, in part at least, to the sudden diminution of the intra-abdominal pressure and consequent plethora of the abdominal veins; the haemorrhage results from imperfect contraction, and is therefore proportioned to the extent of the uterine paresis. Spontaneous reduction of incomplete inversion is not uncommon. Cases of spontaneous reduction of the complete form have likewise been observed, referable, accord- ing to Spiegelberg,* to retrac- tion of the ligaments acting upon the uterus while in a re- laxed condition. The diagnosis is not diffi- cult. The inverted uterus can only be mistaken for a fibrous polypus, but liy careful external and bimanual palpation the de- monstration of the absence of the uterine tumor above the symphysis would guard against this error. Tlie prognosis depends u})on the promptitude of the operator in restoring the fundus to its normal position. Still, accord- ing to Crosse's f statistics, one third of the patients died either at once or within a month of the occurrence of the accident. Treatment consists in pressing the fundus upward with the fingers or with the closed fist. To avoid tearing the uterus from its vaginal attachments, care should be taken to employ counter-pressure with the disengaged hand upon the upper border of the funnel-shaped depres- sion. If the placenta is detached to any great extent, its separation should be completed before replacement ; if adherent, no time should be lost, but placenta and fundus should be pushed back together. If the cervix is contracted about the inverted portion, an anaesthetic should be given, and taxis should be employed. I can speak from ex- * Spiegelberg.

In a case seen by me in conjunction with Dr. Henry E. Crarapton, of New York city, thirty-six hours after delivery, I succeeded, afttr several fruitless efforts, in restoring the uterus by the following method : First, the fundus was pressed upward through the cervical ring by the thumb and fingers. The partially reinverted uterus was clearly felt through the thin abdominal parietes, but it was found impossible to Fig. 227. — First stage of replacement.

The hand was therefore held steadily in place, with no attempt at a forward movement, for about ten minutes. This was done with the intent to procure a relaxation of tho constriction by means of continuous press- ure. Then the thumb was withdrawn, and the circular uterine fold, which still hung deep into the vagina, was pressed up on one side by the fork formed by the thumb and index-finger. Finally, by indent- ing the raised fold by the thumb, and at the same time making counter- pressure upon the uterine ring through the abdominal walls, I was en- abled to push the entire mass by the ring, and had the pleasure of feel- ing the remainder of the inverted organ roll spontaneously into posi- 39 g-j^Q THE PATHOLOGY OF LABOR. tion. Tlie diagrams drawn for me by my friend, Dr. L. M. Yale, will help to make intelligible the mechanism of the manoeuvre. If the reinversion proves successful, the hand should be allowed to remain within the uterus, and external pressure should be employed until contraction is secured. The subsequent treatment does not differ from that for uterine atony, already considered in connection with post-particm hemorrhage. CHAPTER XXXIII. RUPTURES OF THE GENITAL CANAL. Rupture of the uterus. — Etiology. — Patliological anatomy.— Symptoms and diag- nosis. — Treatment. — Prophylaxis. — Treatment after rupture. — Rupture limited to the peritoneal covering of the uterus. — Perforation from pressure. — Lacera- tions of the vaginal portion. — Laceration of the vagina. — Laceration of the vulva. — Thrombus of the vulva and vagina. — Rupture of the pelvic articula- tions. The genital canal may be ruptured in any portion of its course. Thus, lacerations may take place through the perina?um and posterior vaginal wall, in the vestibulum, in the fornix of the vagina, in the cervix, in the uterus, and in the pelvic articulations. Rupture of the Uterus. — Ruptures of the uterus, for the most part at least, start from the lower segment, and thence extend upward to- ward the body and fundus, or downward toward the vagina. They are termed complete when the rent extends through to tlie abdominal cavity, and incomplete when confined to either the muscular layers or to the peritonaeum. Bandl reported 19 cases in 40,614 labors (1 : 2,137), occurring in nine years in the Lying-in Hospital at Vienna. Jolly, in Paris, found 230 cases in 782,741 labors (1:3,403), but he excluded from his list lacerations of the cervix. Harris, whose authority as a statistician is of the highest, estimates in the United States one case of ruptured uterus to four thousand births. I found 47 deaths from this cause recorded in New York between 1867 and 1875 inclusive, or about one death in six thousand labors. But it is hardly probable that these figures rep- resent anything like' the actual mortality ; for, whereas in 1875 eleven deaths were returned, there were but four recorded in 1867, and none in the years 1871 and 1872. It is not likely, moreover, that the 47 cases include any other than spontaneous ruptures, as naturally very few physicians are brave enough to record as such ruptures due to violent obstetric manoeuvres. Hugenberger estimated the mortality from ruptured uterus at 95 RUPTURES OF THE GENITAL CANAL. 611 per cent, C. Brann * at 89 per cent. Their statistics were made up from hospital records. Jolly reported in civil practice 100 saved in 580 cases ; but this Harris f believes to be too favorable a showing, as the proportionate loss is much less in published than in unpublished cases. Of late years the treatment of this condition has, however, furnished somewhat better results, and a careful study of the circumstances which favor its production is capable of at least furnishing the ground- work of a rational prophylaxis. Etiology. — Rupture of the uterus may take place spontaneously as the result of defective resistance offered by the uterine walls to the pressure of the ovum, or it may owe its origin to some external mechanical force. Kupture of the fundus is a very rare exception. It may take place under special abnormal conditions, as in the one-horned uterus, in imbedded myomata, when cicatrices exist as the re- sult of previous Ca^sarean sec- tion, and in retrograde changes of the uterine walls. It is the great merit of Bandl J to have shown that nearly all ruptures begin in the lower seg- ment, and are preceded by an ab- normal thinning and distention of that portion of the uterus situ- ated between the ring which bears his name and the os ex- ternum. In normal labor it will be remembered that during a pain the fundus and body thick- en, while the lower segment is stretched by the ovum. So long as no obstacle exists which hinders the progression of the ovum or the fcetus, this process ends in the conversion of the uterus and vagina into one continuous canal. In such cases the contraction ring is often but slightly indicated, and is found in the neighborhood of the pelvic brim. If, however, the descent of the foetus is prevented by any cause, the resistance of the ligaments which hold the uterus in position is over- * Braun, Lehrbuch der gesammt.

Fig. 228. — Diagram showing dangerous thinning of the lower segment, owing to the non- descent of the head in contracted pelvis. (Bandl.) gj^2 THE PATHOLOGY OF LABOR. come by the retraction of tlie fundus and body, and as a consequence the contraction ring is withdrawn upward, the lower segment is thinned, and in extreme cases nearly the entire uterine contents may occupy the distended passive inferior segment. Under these circum- stances it is possible at times to detect by palpation the contraction ring a hand's-breadth above the pubes, or even in the neighborhood of the umbilicus. The stretching of the tissues is most pronounced in the upper portion of the lower segment, diminishing below until the vagi- nal portion is reached, which, of course, is not subjected to tension. Now, when, as the result of the birth of any considerable portion of the child into the obstetrical cervix — as the stretched lower uterine segment has been termed by Spiegelberg — the tissues of the latter are distended so as to form little more than a membranous covering, the conditions which threaten rupture are established. Thus, contrac- tility is impaired; with each recurring pain, the child, driven still farther from the uterine cavity, increases the pressure upon the already enormously distended lower segment ; gradually the thinned tissues separate ; the presenting part of the child is forced into the opening ; at the height of a pain complete separation of the muscular tissues takes place ; the peritoneum is lifted up from the underlying tissue, and finally, in the majority of cases, is torn through, permitting tlio partial or complete passage of the child into the peritoneal cavity. The emptied uterus then contracts, and the expulsive pains cease. The conditions which specially lead to a dangerous attenuation of the lower uterine segment are the pressure of a hjdrocephalifi head, a neglected shoulder presentation, and where the descent of the child is hindered by pelvic contraction, by cicatricial tissue or by tumors obstructing the parturient passage. Rupture is favored whenever augmented pressure, as in lateral obliquity and anteflexion of the uterus, and in transverse presentations, is brought to bear upon a limited area of the already overdistended tissues. There are very great individual differences in the distensibility of the uterine and cervical tissues. In Avomen who have borne many children, rupture may occur before any great degree of stretching has been reached. In the case of which the post-mortem appearances are given in Fig. 229, spontaneous rupture occurred in the tenth preg- nancy. Labor commenced at noon, and the membranes, wliich had begun to protrude through the vulva, broke near midnight. The pains then became slow and feeble. At about three o'clock in the morning sudden collapse occurred. On my arrival, thirty minutes later, I found the pulse scarcely perceptible, the breathing hurried, and the extremi- ties cold. As the head was well down in the pelvis, I applied forceps, and extracted without effort a dead child weighing ten and a half pounds. Previous to the collapse the patient had felt comfortable. At the moment of its occurrence a distinct snapping sound was heard by RUPTURES OF THE GENITAL CANAL. 613 the hospital physician, Dr. J. D. Griffith, who sat several yards distant from the bedside. The patient stated that she felt a sensation as though a warm fluid was pouring into the abdominal cavity. As the pelvis was ample and the presentation normal, and as there was no irregularity of the labor-pains, tlie rupture could only be accounted Fig. 829— Case of ruptured uterus (anterior surface), a, body of uterus ; 6, ring of Bandl ; C-, thrombus, shining through the peritonaeum. for by assuming a vulnerability of the uterine tissues, and probably a clamping of the anterior lip between the head and the pelvic wall. On the other hand, so great is the distensibility of the tissues in certain cases that the foetus may pass entire from the uterus into the cavity of the obstetrical cervix without laceration ensuing. Bandl found that of 54G cases of rupture but sixty-four were in primiparge. Their preponderance in multij^arae is for the most part Q^^ THE PATHOLOGY OP LABOR. the result of the laxity of the round and lateral ligaments of the uterus, which offer accordingly but slight resistance to the recession of the contraction ring ; of the stretched condition of the abdominal parietes, which jjermits obliquities and anteflexion to take place ; and ■of the separation of the recti muscles, which interferes with the use of the abdominal compress. Of course, the loss of vitality over limited areas, resulting from the compression to which the uterine walls are frequently subjected in deformed pelves, enhances the disposition to rupture. It is likewise obvious that the existence of extreme cervical distention should not be overlooked in cases where operations are rendered necessary. The old prejudice against all operations within the uterine cavity while the cervix is undilated is based in great measure upon the real danger of laceration which proceeds from the association in many cases of tlie foregoing condition with difficult labor. Pathological Anatomy. — Kupture may occur in any point of the obstetrical cervix. More commonly it takes place upon the side. Owing to the right lateral obliquity of the uterus, and the greater frequency in shoulder presentations of head-left positions, the left side is oftener affected than the right. The laceration may follow any direction. Longitudinal tears occur usually in shoulder presenta- tions, or where the head is of disproportionate size ; the circular rents are for the most part limited to generally contracted pelves. The combination of a transverse with a longitudinal tear, the two meeting at a right angle, is not uncommon. It has been maintained on theo- reotical grounds that spontaneous rupture is arrested by the contraction ring. This is certainly the rule where tiiere has been no art interven- tion, but cases reported by myself and others show that exceptionally the rent may extend through the ring to the fundus when there has been no interference. When the uterine walls possess unusual distensibility, a laceration may take place in the peritonaeum while the muscular structures remain intact. Again, in some cases, ow- ing to an excessive elasticity of the peritonaeum, the latter does not give way even when the child has partially escaped from the uterine cavity. These incomplete ruptures are more likely to occur upon th(! sides of the uterus, at the site of the folds of the broad ligament, though, owing to the relatively loose attachments of the peritonaeum at the lower segment, incomplete ruptures are not necessarily confined to these points. The peritoneal wound is usually more extensive than the uterine, but this rule has its exceptions. When the peritonaeum is late m giving way the opening may be of small dimensions. Some separation of the peritoneum from the underlying structures is usually found in the neighborhood of the rupture. Its extent is dependent upon the degree of tension to which the membrane was subjected before laceration took place. At the body of the uterus the RUPTURES OF THE GENITAL CANAL. (515 close connection between tlie peritonaeum and the externul musculur layer renders a separation at that point an impossibility. In the case represented by Fig. 229 the peritoneum was, on the other hand, dissected away anteriorly by effused blood as far as the umbilicus. Hfematomata are the rule in incomplete ruptures ; in complete ones they are also found in cases where the peritoneum has been late in giving way — i. e., after a cavity of considerable size lias been formed by its detachment. The borders of the laceration are ragged. The body of the uterus rises high up in the abdominal cavity, and is inclined to the side opposite to that at which the rupture has taken place. Symptoms and Diagnosis. — The occurrence of rupture may often- times be foreseen and guarded against by the early recognition of ex- cessive cervical distention. The development of the latter is possible in any case of obstructed labor. Unless the abdominal walls are very thick, the boundary between the firm, hard body of the uterus and the thinned lower segment, in the form of a transverse or an oblique furrow, may be made out by palpation through the abdominal walls. Upon the sides the round ligaments, even between the pains, have the feel of tense cords. Usually the stretching of the cervix is associated with violent pain, with increased rapidity of pulse, and an anxious expression of countenance. If rupture occurs, the uterus inclines to the opposite side, the present- ing part recedes, and often vomiting^ets in. When the rupture takes place gradually, violent manifestations are exceptional. The pains even then may continue, and force the foetus into the abdominal cavity. In cases of sudden rupture the pains cease instantly, and symptoms of collapse usually make their appearance.* Vomiting, prostration, the cool skin, the rapid pulse, the drawn features, all point to internal haemorrhage and shock. Blood flows from the vagina, and the present- ing part recedes from the joelvic brim. Certainty in diagnosis is reached when the uterus upon palpation is found to be empty and the outlines of the child can be made out through the abdominal coverings. If rupture takes place after the presenting part has become fixed in the pelvis, internal exploration is often out of the question previous to the birth of the child. Usually, however, the existence of the rent is easily made out by the examining hand. *I employ here the term "usually" because in one instance a patient was brought to the Bellevue Hospital in a fairly good condition. On examination I found the child in the uterine cavity, but the head had receded, and, to my surprise, my hand passed through a large rent to the intestines. Winckel (Lehrbuch der Geburtshiilfe, p. 5G3) ascribes sudden symptoms of collapse to the direct introduc- tion of large quantities of poison germs into the abdominal cavity, whereas in cases of traumatism without mycosis the result depends upon the suddenness of the oc- currence and the quantity of blood lost. Q^Q THE PATHOLOGY OF LABOR. The passage of the child through the opening into the abdominal cavity is usual ; but to this rule there are exceptions. I have seen three cases, two complete and one incomplete, where the child remained within the uterus in spite of the existence of extensive laceration. The symptoms of incomplete rupture are, at the time of its occur- rence, of less severity than the foregoing. The pain and collapse, the cessation of uterine contractions, and the recession of the presenting part are usually absent. Often the rupture may have existed for some time without appreciable phenomena pointing to its existence. The frequent pulse is the most constant sign. As incomplete ruptures have almost always a lateral situation, large vessels are apt to be injured and the internal haemorrhage to be profuse. In rare cases subperitoneal emphysema, due to the entrance of air or gases arising from putrefaction, may be recognized by the hand or by the ear on the anterior surface or upon the sides of the uterus, and ex- tending sometimes into the iliac regions. Treatment — Prophylaxis. — In view of the serious prognosis in cases of uterine rupture, the question of prophylaxis is one of peculiar in- terest and importance. The outcome of Bandl's demonstration regard- ing the etiology of the accident is to place in a clear light the responsi- bility of the physician for its occurrence. If it can not always be foreseen and prevented, there is no excuse for the accident when the development of the recognizable conditions which lead to it is over- looked, or where palpable warnings are neglected. In multiparte with contracted pelves, where, as a consequence of previous pregnancies, the ligaments are lax and the lower segment is soft and distensible, it is desirable, so soon as the child is viable, to induce premature labor, and thus to diminish the disjoroportion be- tween the head and the pelvis. If the conditions described by Bandl begin to develop during labor, lateral obliquities should be corrected, either by placing the patient upon the side to which the presenting part is turned, or by fixing the uterus with compresses and a bandage in the median line. In hydro- cephalus, puncture should be resorted to at an early period. If the recession of. the body of the uterus continues, and the head is movable, version should be performed, provided always that it can be accomplished without violence. In the introduction of the hand, every pains should be taken to correctly appreciate the additional strain to which the cervical tissues are subjected. When an extremity has been seized, and tractions are made, the contraction ring which separates the body from the lower segment interferes alike with the descent of the breech and the ascent of the head into the fundus. If rude force is employed, the increased pressure that temporarily is ex- erted upon the side of the cervix, which is bulged by the presenting part, can easily give rise to rupture. To avoid any unnecessary strain RUPTURES OF THE GENITAL CANAL. 617 during version, counter-pressure should be made over the fundus of the uterus by a trained assistant, while the operator controls the direc- tion of the head by means of his free hand laid upon the abdominal wall. If the head is fixed in the pelvis, the forceps is usually available. If, however, the head is movable and version contra-indicated, the for- ceps is not likely to help the child, and is nearly certain to injure the mother. In a few cases it is possible to press the head into the pelvis by force exerted with the two hands from above the pubes. If craniotomy becomes necessary, Bandl advises seizing the head in the forceps before using the perforator, as even mod- erate pressure upward in the tense state of the cer- vix may lead to laceration. In neglected shoulder l)resentations, pains should be taken to ascertain whether the child is living before performing version. This can at times be ac- complished by passing the hand upward near the shoulder and feeling for pulsations of the cord. In all extreme cases, the continued retraction of the uterus, by limiting the placental area, is apt to produce fetal asphyxia. If the child is living, the conditions are usually such that version can still be performed, provided care be taken at the same time to press the head from without toward the uterine axis. Excessive distention of the cervix develops much more slowly in primiparae than in women who have had previous confine- ments. If the child is dead, or where version is impracticable, decapi- tation should be employed to release the patient from further danger. Treatment after the Occurrence of Rupture. — If rupture is sus- pected to have taken place, the child should be delivered without de- lay. The means of delivery should be selected with the view to enlarge the opening as little as possible. In vertex presentations, if the diag- nosis is clear, it is advisable to perforate and extract with the cranio- clast, as the child is rarely born alive where rupture has taken 2:)lace. If the head only has passed through the rent, if the os is dilated, and if the feet are felt near the pelvic brim, the withdrawal of the child Fig. 230. -Retraction in a case of shoulder presentation. (Bandl.) g^g THE PATHOLOGY OF LA15011. by version is usually effected without difficulty. If, however, the pel- vic contraction is extreme, if the cervix is rigid, or if so large a portion of the foetus has passed into the peritoneal cavity that its withdrawal is liable to increase the size of the laceration, it is doubtless better to incise the abdomen at the linea alba, and deliver through the artificial opening. There is not only less shock, but the opening into the ab- domen enables the operator to remove effused blood and amniotic fluid from the peritoneal cavity. Still, the not uncommon impression that the ruptured uterus furnishes a promising field for abdominal surgery does not take into account that in many of the cases where laparotomy is clearly indicated, the patient is practically moribund. The employ- ment of the suture to close the uterine wound, in view of recent Cesa- rean successes, sounds reasonable ; but it must be remembered that, with ragged borders infiltrated with blood, with the stripping of the peritonaeum, and with air or gases sometimes infiltrated into the sub- peritoneal connective tissue, the conditions for union are in no wise comparable to those which exist when a clean incision is made into a perfectly normal muscular organ. However, in the cases gathered by Harris for the United States, there were 53i^ per cent of recov- eries. The supravaginal amputation of the uterus, wiih suture of the peri- tonaeum below the ligature, promises fairer results, though the deep situation of the tear makes it difficult to secure a healthy pedicle. Godsen collected seven cases, all of which terminated fatally, but more recently Slavjansky, Krassowsky-Halbertsma, jMermann, Fontana, Coe, "VViedow, and Kehrer have each reiwrted a recovery under seemingly desperate conditions.* If the abdomen is opened, even when hesitation is felt about the deep suture or ablation, there should be none concerning the em- ployment of the peritoneal suture, by means of which the complete rupture is converted into an incomplete one with its more favorable prognosis. When the child can be removed by the natural passages without an increase of the laceration, and the latter is confined to the lower seg- ment, in all cases where rupture is incomplete, or where the uncer- tainty as to the extent of the injury leads the physician to shrink from abdominal section, clots in the vicinity of the opening should be re- moved by the hand, firm contractions should be excited by manual pressure, and every pains should be taken to secure by irrigation an antiseptic condition of the genital tract. As death, when not due to shock or haemorrhage, is most frequently the result of septic changes in the retained fluids, a priori drainage ought to prove an essential aid to treatment. The correctness of this prevision has been realized by successes obtained through its instru- * Vide paper by H. C. Coe, M. D., Med. Record, Nov. 2, 1889. RUPTURES OP THE GENITAL CANAL. 619 mentality by Frommel,* Mosbach, Graefe, Felsenreic]i,t Hecker,J and Mann.* The plan recommended by the latter, based upon the experi- ence of Gustav Braun's clinic, consists in taking a large-sized piece of drainage tubing, and bending it in the middle, so as to leave the ex- tremities of equal length. A large opening should then be made at the arch, which is to be introduced through the point of rupture, and the descending branches of the tube should be fastened together to prevent the formation of a bridge of tissue between them during the process of healing. The upper end of the drainage apparatus should be passed from a half-inch to an inch beyond the torn borders of the uterine wound, and the lower ends stitched with silk to the posterior commis- sure. Over the vulva and the apparatus there should be placed an antiseptic dressing, which should be changed several times daily. After the first four or five days, by which time it may be assumed that pro- tective adhesions will have formed in the neighborhood, a regular irri- gation of the wound with a two-per-cent solution of carbolic acid should be carried out, with a view to prevent a septic poisoning from the decomposition of the pus and the lochia. More recently, in the discussion before the Geburtshiilflich Gynaekolo- gischen Gesellschaft,|| of Vienna, it was recommended to secure drain- age, either as above, by rubber tubing, or by means of lamp wicking (fifty threads) prepared with iodoform, while the vagina was loosely packed with iodoform gauze. Drainage should be sujiported by every means calculated to maintain uterine contractions and check haemor- rhage. These objects are best secured by manual compression of the uterus, either with or without conjoined pressure of the aorta, to be continued if necessary for hours. Before leaving the patient a grad- uated compress should be placed around the uterus, to maintain firm uterine contractions, or, what I regard as preferable in these and analo- gous cases, a rubber water-bag, which adjusts itself to the contour of the uterus and is hardly less effective than the hand itself. In the Vienna discussion alluded to Dr. Fleischman stated that in eighteen cases of anterior rupture, five of which had been treated by drainage, all died ; whereas, of fourteen cases of posterior rupture, of five treated by drainage all recovered. In certain of the reported cases of recovery where drainage was eni- * Frommel. Zur Aetiologie unci Therapie der Utenisruptur, Ztschr. f. Geburtsh. und Gynaek., Bd. v.

Drainage in the cases referred to was employed in complete as well as in incomplete ruptures.

Rupture limited to the Peritoneal Covering: of the Uterus.— This very rare form requires but brief mention. In all but ten cases have been reported. It occurs nnder apparently normal conditions, without premonitory symptoms. It is supposed to be due to deficient elasticity of the peritonaeum, and may take place during either pregnancy or labor. Death in the known cases resulted from internal hoemorrhage, from peritonitis, or from shock (Spiegelberg). Perforation from Pressure.— In stud}'ing the influence of the con- tracted pelvis, we have already had occasion to consider the origin of circumscribed losses of substance in the uterus due to the pressure of the pelvic walls. In the present connection it is only necessary to state that they are more frequently followed by recovery than the ruptures, in favorable cases exudation closing the opening and the necrosed tissue passing away through the vagina. Lacerations of the Vaginal Portion of tlie Cervix. — Lacerations at the OS externum of moderate extent are the nearly constant concomi- tant of physiological labor. The " show " of monthly nurses consists of mucus tinged with blood furnished from the slight tears which are produced during the passage of the head through the cervical orifice. At times, however, these lacerations may assume a pathological impor- tance, reaching upward to the vaginal junction, or even, in extreme cases, stretching outward through the upper portion of the vagina. At the time of their occurrence, they give rise to no special symptoms. After the birth of the child, they may become the source of post-jyar- tmti haemorrhage, or they may interfere with involution, and during childbed expose the patient to the risks of infection. In after-life they furnish the foundation of a multitude of uterine disorders (Emmet). They occur most frequently in primiparae, especially elderly ones ; in oedema of the cervix ; in cases where the anterior lip, pushed downward by the occiput, is caught between the head and tlie pubic walls, and thus is prevented from retracting simultaneously with the posterior lip ; and as a consequence of obstetrical operations. Severe lacerations extending above the vaginal junction are most frequently produced in pelvic deliveries, where the head is extracted by force through an imper- fectly dilated os. Most commonly these lacerations follow a longitudinal direction. In rare cases, where there is extreme rigidity of the os externum, or where, after the escape of the amniotic fluid, the head distends the an- terior lip without pressing upon the os, a transverse rent may occur through which the child may pass. Sometimes a longitudinal tear may be combined with one running transversely, the lip then hanging by a pedicle to the uterus, or the entire lip may be torn off. Isolated cases RUPTURES OF THE GENITAL CAXAL. 621 of so-called annular laceration have been reported, where the transverse rent has extended through the whole vaginal portion, so that the lower segment has been detached in the form of a ring. In these cases hsem- orrhages very rarely if ever occur. In addition to the ordinary principles which should govern the management of every labor, Bandl lays great stress upon the pushing up of the confined anterior lip as an important prophylactic measure. Haemorrhage due to cervical laceration should be controlled by clos- ing the rent with silver or catgut sutures. In view of the bad light by which the operation has usually To be performed, the suggestion of Schroeder, to draw the cervix with the volsella forceps outside the vulva, while an assistant pushes the uterus down into the jDelvis from above, is worthy of being borne in mind. With the wounded parts thus exposed, the reparative operation advocated presents scarcely appreciable difficul- ties to even the least surgical of attendants. If no hemorrhage occurs, cervical lacerations are rarely recognized except by physicians who take pains to invariably investigate the j^ost- partum condition of every patient. As a rule, with strict antisepsis they heal rapidly during involution. Nevertheless, it is my present cus- tom to close all extensive lacerations with a continuous catgut suture. After the expulsion of the placenta the operation is easy, is devoid of risk, and is followed by speedy union of the torn surfaces. For the gynaecological expert Veit recommends the passage of the sutures without the aid of the speculum, by the touch alone. This he accom- plishes by means of a needle seized at right angles with a long-handled needle holder. The needle he passes first through the anterior, and then through the posterior lip, under the guidance of two fingers of the left hand, while the fundus is depressed by an assistant from above. Traction upon the first suture materially aids in the introduction of the others. Lacerations of the Vagina. — Vaginal lacerations vary in gravity according to their extent and position. In the upper part of the canal they are, as a rule, continuous with ruptures begun in the uterus or in the vaginal portion. In contracted pelves, where, owing to excessive retraction, the head fills the vagina without entering the pelvic brim, isolated lacerations of the vagina may follow the same general causes as those which give rise to rupture of the uterus. Per- haps the most common vaginal lesion is that produced by the un- guarded blades of the forceps when applied diagonally in j)lace of directly to the sides of the child's head. In the lower portion of the canal these lacerations heal speedily without serious symptoms, provided cleanliness be maintained from the first. Lacerations of the fornix only are of great importance on ac- count of their proximity to the peritonaeum, and because of the exposure of the parametrium to septic absorption. The immediate closure, there- g22 THE PATPIOLOGY OF LABOR. fore, of these rents with silver sutures ought to be attempted. Owing to the laxity of tlie tissues, the difficulties of reaching the wound are not excessive, while the dangers to be forestalled are of a peculiarly threatening character. The orio'in and nature of fistulous communications with the blad- der and the rectum have already been considered in connection with the pathology of labor. Eesulting for the most part from necrosis due to pressure, they are rarely the immediate sequela? of childbirth, the sloughing of the dead tissue taking place during the course of the puerperal period. The treatment in such cases belongs properly to the domain of gynaecology. The closure by suture is only available as a plan of treatment in cases where complete laceration through the tissues into the neighboring organs takes place during labor, as the consequence of rudely performed obstetrical operations. Lacerations of the Vaginal Orifice.— Owing to the small size of the vaginal orifice, tears through the mucous membrane and erosions of the vulva, and, in primiparge, the rupture of the frenulum, are to be accounted as the almost inevitable consequences of childbirth. They are the principal cause of the external soreness experienced after labor. In healthy localities they heal rapidly, and are of but trivial impor- tance. Of greater moment are deep perineal lacerations and those of the vestibulum. Lacerations of the Vestibulum. — Tears limited to the mucous mem- brane are usually found after labor at the sides of the clitoris. In exceptional cases these tears may involve the underlying erectile tissue (bulbs of the vestibule), and become the source of profuse or, when overlooked, even of fatal haemorrhage. The blood, which may be either venous, arterial, or of mixed origin, spurts in jets or oozes as from a soaked sponge. The recognition of the lesion is easy upon inspection. It should always be thought of as a possible cause of post- partum haemorrhage in every case where the flow continues after the contraction of the uterus. The bleeding may be temporarily arrested by pressing the tissues with the finger against the inner surface of the pubic bones until the expulsion of the placenta. Ligatures to the bleeding vessels, owing to the complexity of the structures, are of no avail. In slight cases a stream of cold water is a sufficient haemostatic. In others, the bleeding requires to be checked by one or two deep sutures introduced so as to bring the torn surfaces into apposition. If the bleeding appears to come from one or two points, the jiinccx liemosta- tiqnes are of service. Styptics and astringents are usually effective, but they possess the drawback of augmenting the pain and soreness. Lacerations of the Perinaeum.— In the chapter upon the :Manage- ment of Normal Labor, the nature, origin, and prevention of perineal lacerations have already been considered. The diagnosis is made by a RUPTURES OF THE GENITAL CANAL. 623 careful inspection of the genital organs after delivery. The extent of the lesion is estimated by including the recto-vaginal septum between the thumb and index-finger. The treatment of perineal laceration consists either in keeping the woman in bed until the wounded surfaces cicatrize, or in bringing the parts into apposition by means of sutures, with the intent to secure primary union. The first plan is sufficient if the wound be of slight extent. If, however, the rupture extends to the sphincter ani, and involves the entire perineal body, the vagina is left without support, rectocele or cystocele ensues,^ the uterus sinks downward and becomes displaced backward, and in the end prolapsus is apt to result. If the sphincter ani and the recto-vaginal wall are involved, inability to re- strain the bowels adds to the discomfort of the patient. This sequence of symptoms, so familiar to gyngecologists, forms an urgent plea for the resort to surgical means to repair the injury. Only a very credu- lous j)erson really believes that he has witnessed union by first inten- tion in extensive ruptures, as the result of tying the knees together and enjoining rest upon the side. The action of the transversi-peri- naei muscles tends to draw the torn surface apart. Moreover, the necessity of separating the knees in passing urine, and to enable the nurse to cleanse the genitalia, makes it impossible to keep them in contact for any lengthened period. To the immediate operation there is no valid objection. It is not difficult, it is not extremely painful, and its performance, as a rule, diminishes the risks of infection and shortens the puerperal period. It is true that the object aimed at may not be attained. If labor has been conducted in accordance with antiseptic principles, if no syphilis ex- ists, and the vitality of the tissues has not been impaired by cedema or long-continued pressure, failure is the exception. The argutnent that the operation is in itself a confession does not deserve discussion. For its performance the patient should lie upon her back, with her hips well over the edge of the bed. Two assistants to hold the knees are of great convenience. In ojjerations requiring the introduction of not more than three or four sutures angesthesia may be dispensed with. In lengthy operations, such as are necessitated by lacerations extending up the posterior vaginal wall, ether should be given in place of chloroform, and its administration should be intrusted to an experi- enced person only. It can not be too often repeated that anaesthesia after labor calls for the exercise of extreme caution. The wound should be prepared by carefully washing away blood and clots with warm carbolized water. For lacerations not extending through the sphincter ani I use Peaslee's needle, which is furnished with an eye at the point, and is set in a wooden handle. It possesses the advantage of strength, a quality of no mean importance in making the circuit of the redundant tissues with which we have to deal after 624 THE PATHOLOGY OP LABOR. labor. I use the silver suture, and after repeated trials have not been able to convince myself that it can be equally well replaced by silk. The first suture should be passed just in front of the anus. It should be entered and brought out about a half -inch from the rupt- ured borders. The others should follow at from one third to one half inch intervals. Each suture should make the entire circuit of the wound. This can be readily accomplished by guiding the point of the needle through the residue of the perineal body Avith two fingers in the anus and with the thumb upon the vaginal surface. To secure a stronger hold for the last suture, the needle should be made to enter the vagina above the upjjer angle of the rent, and the wire should be made to traverse a portion of undenuded tissue before completing the circuit. In closing the wound, great pains must be taken not to twist the sutures too tightly, as in that case they are apt either to cut out or to produce sloughing. Sometimes, in rents extending through the sphincter ani and the recto-vaginal septum, the simple perineal sutures will effect a satisfac- tory union. Thus, in a patient at the Emergency Hospital, with a laceration extending nearly to the cervix, and whose condition pre- cluded a lengthy operation, I obtained an excellent result by passing a single wire above the angle of the wound, and twisting the ends out- side the perineum. As a rule, however, it is desirable to adjust the edges with great care, first closing the rent upon the rectal side, then bringing together the split in the mucous membi'ane upon the vaginal side with transverse sutures, and finally bringing the lower borders of the perinaeum together by a separate operation. This disposition is the so-called triangular suture of Simon.* It requires fine needles, a needle-holder, an adjuster, a wire-twister, and, in fact, all the para- phernalia of the gynecologist. The length of the operation renders necessary an anaesthetic, which should be ether rather than chloro- form. The disgusting condition of a patient with laceration through the recto-vaginal septum, where the healing process has been the result of granulation, justifies the attempt to secure immediate union. The requirements in the way of after-treatment are very simple. The urine should be drawn every four to six hours with a catheter, until the patient is able to pass her water spontaneously ; the bowels should be kept open with salines ; and the knees should be tied loosely, to remind the woman of the desirability of keeping them in contact. The wound should be kept scrupulously clean. Whenever urine has been passed the perineum should be washed with warm carbolized water, then dried, and sprinkled with iodoform. Pads of iodoform gauze should be placed to the sides of the sutures to prevent them from causing ulceration of the adjacent soft parts. A little opium * Vide Garrigues's excellent paper entitled The Ob.stetric Treatment of the Permsura, Am. Jour, of Obstet., April, 1880. RUPTURES OF THE GENITAL CAXAL. ^25 may be given, if the pain experienced is considerable. Pain in child- bed from any cause helps to depress the vitality. The perineal sutures should be left a week in situ. Many ^Jromising cases are spoiled by removing the sutures too early. The vaginal sutures may be allowed to remain until the external union is sufficiently solid to permit the introduction of the speculum. Catgut sutures for the rectum are to be preferred when they can be obtained of good quality, as they obviate the necessity of future removal. For the more superficial lacerations of the perineum the serves fines invented by Vidal de Cassis, and extensively used in Vienna, have been warmly advocated in this country by Professor M. D. Mann,* and by Garrigues.f My own experience with them has not been fortu- nate ; but the better results from their use in the hands of their sup- porters recommend them to trial. Thrombus of the Vagina and Vulva. — Hfemorrhagic effusions into the external organs of generation occur with greatest frequency in the labia majora, more rarely in the labia minora, and occasionally be- tween the superficial and median fasciae of the perineum. These ex- travasations may form tumors beneath the subcutaneous or submucous tissues of the vulva or vagina, which vary in size from that of a hen's egg to that of a child's head. As a rule, the blood is poured out into the cellular tissue seated below the diaphragm of the pelvis. The ex- travasation may, however, stretch upward along the vagina to the cel- lular tissue of the uterus, then posteriorly beneath the peritoneum to the kidneys, and around in front to the navel and laterally to the iliac fossae (Winckel). The source of the hasmorrhage may be venous or arterial. The vessel from which the hsemorrhage takes place is usu- ally situated in the lower portion of the vagina ; in less frequent cases, in the vulva. Symptoms. — The first sensation experienced at the time of the rupture is usually one of intense pain, proportioned to the size of the tumor and the rapidity of its formation, though in a case witnessed by Professor Barker J this symptom was absent. As the effusion con- tinues, swelling of the vulva, usually upon one side, results, and the skin becomes blue and nearly translucent. The patient complains of pain, and feels faint, while her lips and cheeks grow white. If the sac contains fluid blood, fluctuation is detected ; after coagulation the tumor has a soft, boggy feel. If the tension increases, the skin may yield, the blood and coagula escape, and, if no means be adoj^ted to arrest the hemorrhage, the patient may die in a few minutes from acute anemia. If the thrombus be of small size and situated low down, the after- * Manx, The Immediate Treatment of Superficial Rupture of the Perinaeum, Am. Jour, of Obstet., November, 1874. f Garrigues, Ioc. cit. % Barker, Puerperal Diseases, p. 58. 40 Q2Q THE PATHOLOGY OF LABOR. symptoms may be of slight importance. The fluid may be absorbed, the walls of the cavity unite, and the tumor disappear entirely. Tu- mors of larger size produce symptoms referable to pressure, such as back-ache, rectal obstruction, and ischuria. The vagina may be so narrowed as scarcely to permit the passage of the finger. Rupture, if not immediate, usually occurs spontaneously in the course of a few days, and is, as a rule, preceded by necrosis of a portion of the de- tached mucous membrane. The most frequent point of spontaneous rupture is at the junction of the larger and smaller labium. If the necrosed tissues become gangrenous, death from septicemia may result. Winckel * sums up the various terminations of thrombus as follows : 1. Death from hsemorrhage, with or without precedent rupture; 2. Death from decomposition of the sac contents, with consecutive sep- ticemia or septico-pyagmia, most frequently after rupture or opening of the sac ; 3. Eupture and recovery ; 4. Rupture, with formation of fistula? ; 5. Absorption without rupture, followed by recovery. Diagnosis. — The diagnosis is simple. The rapid development and increase of the tumor, its bluish color, its elastic or fluctuating char- acter, the sharp pain, and the acute anaemia, occurring independently of uterine hemorrhage, sufficiently point to a sanguineous effusion into the subcutaneous cellular tissue. The extent of the tumor must be determined by rectal and vaginal exploration. It is only at the begmuing that it will be found possible to ascertain the seat of the hemorrhage, whether in the vulva, vagina, or perineum. Sometimes, after rupture and the discharge of the clots, the bleeding vessel may be detected. Etiology. — The formation of the thrombous tumor, with rare excep- tions, takes place during or shortly after labor. If the vessel rupture in advance of the presenting part, the effusion may be immediate and furnish an obstacle to delivery, or the descent of the foetus may check the hemorrhage for a time, to break out afresh after the labor is ended. In rupture due to necrosis consequent upon pressure, the hemorrhage does not, of course, take place until sloughing occurs. Rupture may follow excessive straining, rapid dilatation of the genital canal, or direct injuries. A varicose condition of the veins does indeed create a pre- disposition to rupture, but is by no means a frequent factor in the pro- duction of the accident. Thus, it was present in but six of the fifty cases collected by Winckel. Prognosis. — The prognosis of vaginal thrombus is serious. Deneux reported twenty-two deaths in sixty cases, a mortality evidently ex- cessive ; Winckel reported six deaths in fifty cases ; Barker reported two deaths in twenty-two cases; and Scanzoni one death in fifteen cases. But statistics like these are apt to give rise to a misleading impression. A thrombus |jer se is rarely a dangerous complication. It * WixcKEL, Die Pathologic unci Therapie des Wochenbetts, 2te Auflage, p. 132. RUPTURES OP THE GENITAL CANAL. G27 may, however, become so either because after rupture no means are adopted to limit the amount of haemorrhage, or because, in unhealthy localities, the tense membrane covering the tumor is liable to become gangrenous, and the vast vaginal wound furnishes at once a congenial soil for the multiplication of septic germs, and an absorbent surface by which the septic poison generated is afforded a ready entry into tiie adjacent cellular tissue. Thus, Barker reports nine cases in pri- vate practice, in all of which the patients recovered. Of thirteen cases in hospital practice, two patients died of puerperal fever. The prognosis is likewise less favorable in cases where there exists at the same time extensive separation of the peritonseum. Treatment. — The conditions of successful treatment are restriction of the haemorrhage and the prevention of septicaemia. Early recogni- tion of the accident is very desirable. So soon as effusion is recognized the forceps should be applied, and the head should be extracted as sjieedily as is consistent with the preservation of the integrity of the maternal tissues. To quote from Professor Barker's excellent treatise : " The exciting cause of the acci- dent is the arrest of the circulation by the mechanical pressure of the presenting part of the foetus. The sooner the pressure is removed, the sooner the danger will be over and the less will be the injury to t!ie parts." Moreover, as we have seen, the head in its descent acts as a tampon, by means of which the haemorrhage, whether external or in the submucous tissue, is temjiorarily held in check. If the tumor in advance of the head is so large that the delivery can not be accom- plished Avithout impairing the vitality of the sac-walls, the danger should be averted by incising the thrombus and turning out the coagula. Haemorrhage after the birth of the child is apt to be very profuse, especially if the sac has been opened either by spontaneous rupture of its coverings or with the knife. So long as the sac-walls are intact, the pent-up blood exercises a considerable pressure upon the bleeding ves- sel. For this reason it is well to cover an opening, if one hapijens to have formed, with lint soaked in a solution of one of the per-salts of iron. The continuance of internal haemorrhage should then be checked by means of a water-bag (a large Barnes dilator will suffice) intro- duced into the vagina and distended with ice-water. The hydrostatic pressure rarely requires to be maintained for longer than half a day, during which time it should be repeatedly removed for a few moments to allow the vagina to be cleansed by disinfectant injections. The urine should be drawn with a catheter during the first forty-eight hours, as every straining effort is to be carefully guarded against. A tamjion of linen rags, or of cotton, is inadmissible on account of the tendency it possesses to excite rapid decomposition in the lochial dis- charges. Immediate opening of the thrombus, followed by em]] tying g28 THE PATHOLOGY OF LABOR. the sac and filling the cavity with lint soaked in astringent solutions, are measures which should, on account of the suppuration likely to be thereby excited, be reserved for cases v/here milder procedures have proved ineffective. The ultimate opening of the sac, after the hemorrhage has once been arrested, is rarely to be avoided. Still, cases are on record where tumors the size of a man's fist have disappeared by absorption. As this is the most favorable mode of termination, every effort should be made to secure such a result. To this end quiet should be enjoined, cold should be employed, and pain should be subdued by opiates. If, however, the tumor increases in size, the skin becomes greatly dis- colored, and vesicles form upon its surface, it is better to anticipate threatened gangrene or rupture by incision. If the circumstances per- mit of delay, it is better to wait three to four days to make sure of the stoppage of bleeding. The best point for laying open the tumor is upon the inner surface of the labium majus. The incision should be two to three inches in length. After turning out the clots the cavity should be irrigated with a bichloride solution (1 to 3,000) and should then be packed with iodoform gauze. Rupture of the Pelvic Articulations.* — Rupture of the pelvic ar- ticulations may take place spontaneously where either inflammation or excessive relaxation of the joints exists at the time of labor. More commonly it is the result of difficult forceps operations performed in cases of contracted pelves. The risk of the occurrence of this accident is especially great when the forceps is applied to the head at the brim and forcible tractions are made in a direction anterior to the pelvic axis. The symphysis is the articulation which is principally exposed to this form of injury, though it is obvious that no increase in the capa- city of the pelvis consequent upon the separation of the symphysis is possible without simultaneous rupture of at least one of the sacro-iliac synchondroses. At the symphysis the rupture is apt to be complete, at the synchondroses the rupture is usually confined to the anterior surface. It may take place in the median line, or upon the side, be- tween the cartilage and the pubic bone. If the injury be slight, the synovial cavity of the symphysis may not be injured. At the synchon- droses, opening of the joint-cavity is inevitable. An excessive degree of the lesion is accompanied by laceration of the vagina, the bladder, and the intervening connective tissue. Occasionally the rupture of the joint is announced by a perceptible sound, by intense pain, and, as the result of the increase in the pelvic space, by rapid advance of the head. In the lighter forms, however, which make up the bulk of the cases witnessed, there are no distinct- * Ahlfeld, Die Verletzungen der Beckengelenke wahrend d. Geburt ui^d im Wochenbett, Schmidt's Jahrbiicher, Bd. 169, 1876, p. 185; Spiegelbero, Lehr- buch, p. 636. PROLAPSE OF THE FUNIS, ETC. 629 ive symptoms at the time of the accident. The pathognomonic sec- ondary manifestations are outward rotation of the thighs and localized pain, increased by movement of the limbs and relieved by fixation of the pelvis. Objective evidence of rupture at the symphysis is afforded by the movements produced at the articulation by alternate pressure upon the ends of the pubic bones and by combined internal and ex- ternal examination. If the rent extends to the vagina, the laceration may be detected by the touch. Separation of the sacro-iliac synchon- droses is rendered probable if violent pain is excited by alternately pressing the anterior portions of the ilia together and then drawing them apart from one another. Bladder disturbances are rare except in cases where the separation at the symphysis is complete, or where the rupture is followed by inflammation and the formation of pus. The treatment consists in sujsporting the pelvis by means of a suit- able bandage, in keeping the patient upon her back, and in maintain- ing strict cleanliness. The bowels should for a time be kept confined. As regards the first indication, Spiegelberg says an ordinary towel properly folded and fastened at the pubes, with care taken to avoid pressure upon the crests of the ilia, will answer all the requirements. Eupture of the pelvic articulations, when not complicated by other lesions, or by puerperal infection, run for the most part a favorable course. During convalescence the patient should wear some form of permanent bandage, such as has been recommended in cases of relaxa- tion of the pelvic symphyses. CHAPTER XXXIV. PROLAPSE OF THE FUNIS, ETC. Prolapsed funis. — Asphyxia neonatorum. — Collapse and sudden death during labor and childlied from thrombosis, from embolism, and from entrance of air into the circulation. — On the extraction of the child in case of death of the mother in pregnancy or labor. — Tympanites uteri. Whex the cord is felt within the membranes next to the present- ing part, a funis presentation is said to exist. After the membranes have ruptured, the cord descends into the vagina, in front of the pre- senting part, and is then said to be prolapsed. Generally the cord occupies one of the hollows upon the sides of the promontory ; less frequently it descends opposite the lateral walls of the pelvis; the site in front of the promontory or behind the pubes is very excep- tional. As regards the frequency of the accident, the experience of individ- uals varies widely. Churchill collected 98,512 cases of labor in which g30 THE PATHOLOGY OF LABOR. it occurred 401 times, or in the proportion of one to 245*5 cases. Dr. Christisen, of Wyandotte, Michigan, met witli it 23 times in 1,516 cases. Meachem met with it 10 times in 931 cases. Mr. Bland met with it, on the other hand, but once in 1,897 cases.* Prolapse of the cord occurs only in cases where the presenting part does not completely occlude the lower uterine segment. It is favored by a long cord, by a deep placental site, by the insertic velamentosa, by oblique and breech presentations, by prolapse of the extremities, by hydramnios, by multiple pregnancies, and, above all, by the con- tracted pelvis. On account of the more frequent concurrence of these conditions in multiparae, the accident is oftener found in them than in primparffi. Duncan f has called attention to what he terms " expression of the cord," i. e., where the cord is squeezed out of the uterus long after the escape of the liquor amnii. Of this phenomenon he says that, during labor and after the discharge of the waters : " All parts of the foetus are propelled, but not at the same rate . . . ; and the rate of progress of parts will vary according to the resistance. More mobile parts will have, in consequence of that mobility, less resistance to encounter, and it is plain that the limbs and the cord are the most mobile of the* solid parts." The diagnosis of prolapsed funis is easy. If necessary, the loo]! can be drawn outside of the vagina. Previous to rupture it forms a smooth, round, compressible, mobile body, not to be confounded with any other floating object liable to be encountered within the ovum. AYhen the pulsations of the umbilical vessels are distinctly felt, the child is dem- onstrated to be alive. In the second stage, however, the pulsations may cease for a moment during a pain, to return again in the ensuing interval. As the heart sometimes continues to beat for a few minutes after the circulation in the cord has ended, it is proper to carefully auscultate before assuming death to have taken place (Spiegelberg). The prognosis, so far as regards the children, is extremely unfavor- able, more than one half dying during labor. This fatality is owing to the pressure to which the cord is subjected during the passage of the child through the pelvis. There are, however, a variety of cir- cumstances which substantially modify the extent of the danger. Thus, in transverse presentations the cord is scarcely or not at all exposed to pressure. In breech presentations the prognosis is good, owing to the soft consistence and small size of the pelvic extremity, and to the fact that, where the life of the child is in peril, the conditions are such as to permit of speedy extraction. * These statistics I have borrowed from an article on the Presentation of the Funis, by Dr. J. G. Meachem, reprinted from The Transactions of the State Medical Society of Wisconsin 1880. t Duncan, On Expression of the Cord, Obstet. Trans., vol. xxi, p. 302. PROLAPSE OF THE FtJ:NlS, ETC. 631 The most serious cases are those where prolapse occurs as a compli- cation of head presentations. Engelmann found that the infant mor- tality in the latter was sixty-four per cent, while in footling presenta- tions it was but thirty-two per cent. Favorable conditions in head presentations are a large, roomy pelvis and preservation of the mem- branes until cervical dilatation is completed. Of unfavorable import are a deep placental site, a contracted pelvis, and early rupture of the membranes. Treatment. — From the foregoing it will be seen that the one indi- cation for treatment in this anomaly is to relieve the cord from press- ure. The conduct of the physician in each individual case will depend upon the presentation and the modifying circumstances. If the head presents, so long as the membranes remain intact, and the dilatation of the cervix is incomplete, an expectant attitude should be maintained. Premature rupture should be guarded against by placing the patient in the latero-prone position, by forbidding her to strain, and by supporting the membranes by means of a moderately distended Barnes dilator introduced into the vagina. It is not ra^-e in this class of cases, as the head descends, for the cord to be withdrawn upward into a place of safety. The more complete the dilatation be- fore rupture, the more rapid the subsequent delivery of the child, and the greater the chance, therefore, of preserving its life. If, however, upon auscultation, there are signs of failing heart-action, an attempt should be made to push the cord upward with the fingers through the membranes. In case of success, in order to prevent a relapse, the sac should be ruptured, and the head should be brought down so as to fill the cervical canal. " ' After rujiture of the membranes, if the cervix is well dilated, the pains are good, and the head enters quickly into the pelvic cavity, the case may be left to Nature. Spiegelberg mentions five cases, in his own practice, where the birth of the child took place so rapidly that no harm resulted from the descent of the cord. If the pains are feeble, and speedy progress is not made, the forceps should be applied. If, after dilatation of the cervix, the head remains high and mov- able above the brim, the forceps should not be employed. It is then dangerous to the mother, and offers but scant hope of proving of serv- ice to the child. The choice in such cases falls either upon reposition of the cord or v^ersion. Reposition of the prolapsed cord, as the milder procedure, should be first attempted. The reposition is most easily accomplished in the knee-chest position, as has been beautifully demonstrated by Gaillard Thomas.* . By the simple plan of reversing the direction of the uterine axis, all the conditions which had previously favored the descent of the * Thomas, Postural Treatment of Prolapsed Funis, Trans, of the Xew York Acad, of Med., 1858. ^32 THE PATHOLOGY OF LABOR. cord are made to promote its return into the uterine cavity. Thus the intra-abdominal pressure is removed, tlie amniotic fluid is retained, the liead is easily pushed to one side so as to permit the introduction of the hand, and the cord tends to glide by its own weight over the de- clivitv furnished by the anterior wall to the fundus. The loop should be seized in the hollow of the hand, and should be carefully sheltered from pressure. It should be shoved beyond the greatest circumference of the head, and, where possible, to the back of the child's neck. As in all cases where the hand has to be passed through the cervix, the uterus should be sustained by pressure from without. AYith the ad- vent of a pain, all manipulation should cease, to be renewed, however, as relaxation follows. If the replacement proves successful, the hand should be withdrawn gradually, while the head becomes fixed in the lower segment. This latter result may frequently be expedited by judiciously directed external pressure. As a precaution against relapse, the patient should be placed in the latero-prone position, with the hips elevated by a pillow. The Postural Trentment of Prolapse of the Funis.— K. F. .T. Birubaum* finds that quite frequent mention has been made by authors of the advantages to be derived from posture in the treatment of cases of prohipsed funis. Tlie works of Camper, published about the middle of the seventeenth century, and referred to by Kiestra, he had no means of obtaining access to. Deventer t considers the subject of prolapsed funis in extenso, takes up its different modifications, its effect upon parturition and the life of the child, and the treatment it demands. In cases where the cord was pressed against either ilium, he directed to place the woman upon the corresponding side, with raised pelvis, and with the hand (right hand if on the left side, and vice versa) to lift the head, replace the cord, then, as seemed advisable, either to bring the head into the pelvis, or to turn and extract by the feet. When the cord was pressed against the pubes or the sacrum, he advised that the midwife should place the woman upon her knees with her body thrown forward, and that, in this position, the accoucheur should raise the head and return the cord ; if the woman should be too weak for this, she should be placed upon the side with one limb drawn up under the body. John Mowbray | advises that the woman, if strong enough, should be placed upon her knees and elbows in cases where the cord lies next the sacrum or the pubes. Henry Bracken, a pupil of Boerhaave,* proposed returning the funis in head presentations, with the woman placed upon the knees, and afterward to bring the fetal head into the pelvis. Ludwig Wilhelm von Knoer || devoted a long chapter to funis presentations. He says: "Introduce the hand so soon as the membranes rupture, and, according to the position of the child, perform either podalic or cephalic version, placing the woman at the same time upon * Monatsschr. f.

Van Kitgen has certainly been the most ardent partisan of postural methods of treat- ment. In his work entitled Anzeigen der mechanischen Hulfen bei Entbin- dungen, published in 1830, he recommends them in a great variety of circum- stances, but not then for prolapsed funis ; but in his Lehr- und Handbuch der Geburtshiilfe fiir Hebammen (Mainz, 1838) he says: "When the funis presents, the midwife should instantly send for the accoucheur; meanwhile she should herself place the woman, if strong enough, upon her knees and elbows, and attempt the replacement of the cord ; if the woman is too weak to admit of this, she should be placed upon her side, with elevated pelvis. That side should be chosen upon which the funis is not situated. If the manipulation is successful, the posture should be maintained to prevent a recurrence of the jjro- lapse." He recommends the position upon the elbows and knees for cases of prolapsed funis and transverse presentations in breech or foot presentations, also where the head is movable above the brim, and where there is no attainable presenting part. He advises returning the funis high up with the hand, and then to let it fall into the uterus, where it would no longer be subjected to pressure. After reposition, place the woman upon her side, with raised pelvis. Sometimes the postural method suffices without any manipulations. Kiestra f advises the position upon the knees and elbows in cases where the cord is felt near the head previous to rupture of the membranes, to prevent the occurrence of prolapse. After the rupture of the membranes, he says, the same position should be employed to facilitate the return of the cord, and should be main- tained until the head is fairly engaged in the pelvis. Where the position could not be endured long enough, he counseled placing the woman in a half-kneel- ing, half-recumbent posture, with the sides supported by cushions. Theobold, in 1860, hit upon the same idea. He considered the most favorable condition for the return of the funis was to place the woman upon her head, but, in view of the difficulty attending the execution of this manojuvre, compromised the matter by suggesting the position upon the elbows and knees. The advantages of the postural method in the treatment of pro- lapsed cord are beyond all question. It is, however, difficult to per- suade the woman to long maintain so constrained an attitude, and the cases are not rare where, in spite of gravity, the cord is exjjressed from the uterine cavity. Efforts at replacement should not, therefore, be long continued. It is impossible to handle the cord for any lengthy period without enfeebling the force of the fetal heart. So soon, there- fore, as it becomes evident that nothing is to be gained by further per- sistence, the hand should be pushed up to the feet, and the safety of the child should be secured by speedy extraction. In cases of con- tracted pelvis the question of version must be decided with reference to the interests of the mother, as a difficult breech delivery complicated by prolapsed funis offers but a sorry prospect of saving the life of the child. * Grundlegung zur Ilebamnien-Kunst, Flensburg and Leipsic, 1756. t Ncderl. Weekbl., April, 1855. 634 THE PATHOLOGY OF LABOR. If the membranes rupture and the cord is prolapsed while the cer- vix is still narrow and rigid, an attempt should first be made to push back the cord with two fingers after placing the woman in the genu- pectoral position. As a rule, however, instrumental replacement will be necessary. I have been in the habit of employing for the purpose, as recommended by Dudan, a large English catheter, which possesses the advantage of forming one of the ordinary properties of the phy- sician. The method of using the instrument is as follows : A piece of tape should first be fastened loosely around the cord, the stylet should then be made to emerge at the e3'e of the catheter, and a loop of the tape should be placed in the angle it forms. By returning the stylet and pushing it forward to the extremity of the tube, the band is held firmly. After replacing the prolapsed cord, the catheter is readily de- tached by the witlidrawal of the stylet. Brauu von Fernwald, who is the author of tlie best of the repositors made expressly for the pro- lapsed cord, says that the catheter is almost the only instrument to which he now resorts. Instrumental replacement is apt to prove a veritable labor of Sisy- phus. As one loop is pushed up another comes down, or the entire mass is returned with infinite trouble to the uterus only at once to be i^ro- jected into the vagina. Roberton has proposed a handy plan for such Cases, which certainly merits a trial. It consists in first passing a piece of twine doubled through an elastic catlieter, so that the loop makes its appearance at the eye. Through tliis loop, a loop of the cord should be drawn. The ends of the twine should then be knotted to prevent them from slipping; the catheter should be armed with a stylet, and should be pushed upward into the uterus, carrying the cord with it. After introducing the catheter, the stylet should be withdrawn, and the instrument should be left behind to keep the cord from again prolapsing. In one case Dr. Ashford* succeeded in attaching the cord to a Gariel pessary. The latter was then carried into the uterus, and in- flated to prevent its expulsion. If neither the cord can be returned nor the child extracted, it is proper to try by Braxton Hicks's method to convert the head presenta- * F. A.

Of course, if the prolapsed funis is associated with pelvic contraction, the rule here- tofore given to consult first the safety of the mother remains the guid- ing one in practice. In face presentations version is indicated, as, owing to the imper- fect manner in which the face closes the uterine orifice, replacement of the cord is not likely to prove successful. If the opening through which the cord makes its way into the vagina is produced by a pro- lapsed extremity, the latter, of course, should be pushed back after the cord has been returned. In footling cases the pressure on the cord does not begin until long after the extremities can be reached and utilized for extraction. In full breech cases, where the size of the pre- senting part might interfere with the funic circulation, where it is pos- sible to return the cord with the hand it is equally practicable to bring down an extremity. In cross-births, before the shoulder becomes wedged in the pelvis the cord is in no danger. No treatment is there- fore necessary, except that indicated by the faulty presentation. Suspended Animation or Asphyxia Neonatorum. Definition. — The term suspended animation is applied to such grades of congenital asphyxia in the living new-born child as are not incompatible with the continuance of its life. A larger number of males than of females are borne asphyxiated, and the children of primi- parae are more liable to this condition than those of multipara. Etiology. — A perfect comprehension of the etiology of suspended animation must be based upon thorough knowledge of the physiology of intra-uterine life and of the conditions necessary to its preservation. During the period of gestation the child remains in a state of apnoea, and the respiratory function necessary to its development is performed by the placenta. So soon, however, as the child is born, in normal cases, the thorax expands, the diaphragm contracts, and pulmonary res- piration is established. The premature establishment of pulmonary respiration while the child is still in the utero-genital passage, owing to the absence of an atmospheric medium, is followed by asphyxia, and is the usual cause of still-births. The reason of the first respiratory movement in the child, whether prior or subsequent to its "birth, has long been a subject for speculation. Omitting earlier views, at present two theories contend for supremacy. The one formulated by Schwartz maintains that in all cases the respira- tory act is due to disturbed placental circulation, and the consequent lack of oxygen in the blood of the child. Preyer, on the other hand, in- sists that respiration is a reflex movement provoked by cutaneous stim- uli. He admits, however, that a venous condition of the blood favors 4 : g36 THE PATHOLOGY OF LABOR. the action of external stimuli by increasing the irritability of the respira- tory centres. As a contribution to the solution of the questions in dispute, Otto Eno-strom* has recently reported a series of experiments made by him upon gravid rabbits and guinea-pigs, in Preyer's laboratory. The ani- mals were strapped to a board, and were then immersed in a saline solu- tion (six per cent), which was kept at blood-heat by a special apparatus. The head of the animal was placed above the fluid. A small incision was then made in tlie abdominal wall, through which a uterine coruu was allowed to escape into the saline fluid. The uterine walls were next opened opposite the mesenteric attachment at the point of least vascularity. As there was no haemorrhage to stain the saline fluid, it was possible to observe the foetuses through the membranes in the clear amniotic fluid. When this experiment was performed with address and dexterity, the exposed foetus remained in a state of apnoea, and the blood in the umbilical vein possessed a bright-red color, in marked con- trast with dark hue of the blood in the umbilical arteries. If now the cord was compressed through the membranes by the thumb and index-finger of the warmed hand, or by self-closing compress- ing forceps applied to the cord near to the placenta, and as far from the foetus as possible, respiration followed in from three to six seconds, and continued until death supervened from asphyxia. The same results followed when the umbilical vein was pricked with a needle, or was divided by scissors. Again, in other cases, to avoid the criticism that external stimuli were not absolutely excluded by the manipulations em- ployed, the mother was asphyxiated by carbonic-acid gas, or poisoned by woorari, or bled to death by opening the carotid. Here, too, soon after the blood in the umbilical vein became of a venous hue, respirations occurred as heretofore, though all manipulations were carefully avoided. It is, therefore, demonstrated that fetal respirations are excited, in the absence of external sources of irritation, so soon as the blood in the umbilical veins becomes darkened, or is cut off from the foetus. On the other hand, in another series of cases, where the amniotic sac was exposed under a blood-warm saline fluid, and the apnoea was not disturbed, Engstrom gently pricked the extremities of the foetus with a needle. Reflex movements were excited, but the apnoea continued. When, however, deep puncture was made, the alae nasi dilated, the mouth opened, and thoracic inspiration was evoked. The effect was, however, momentary, and the apncea returned. Again, in order to reduce the disturbance of the placental circulation to a minimum, Engstrom, following a method invented by Preyer, seized the head of a foetus with the thumb and index-finger through the abdominal walls, and then cut through the abdominal coverings, the uterine walls, and amniotic sac to the nose of the animal. The nose * Ueber die Ursachen der Ersten Athembewegungen. PROLAPSE OF THE FUNIS, ETC. 637 was then lifted above the saline fluid and exposed to the atmosphere. By means of powerful currents of induced galvanism applied to the nasal organ, respiratory movements were excited, but ceased when the current was removed. It seemed doubtful, however, whether inspiratory acts did occur in either series of experiments so long as the placental circulation was completely undisturbed. The existence of apnoea in the foetus is not conclusive evidence that the opening of the uterus or the compression of the uterine walls produces no derangement in the blood- currents of the placenta. The results were often negative at the begin- ning of the experiment, but, as the blood in the umbilical vein darkened, the electric and mechanical irritants produced more and more marked effects. From these experiments it becomes evident that when the placental respiration is suspended, the accumulation of unknown materials in the blood is capable of exciting the respiratory center in the medulla oblongata of the foetus without the aid of peripheral stimuli ; but that the latter are capable of exciting the respiratory act before the internal stimuli have increased sufficiently to induce independent action. Again, it is a familiar fact that in moderate degrees of asphyxia in the new-born, after the irritability of the medulla has been lowered to a point at which no response follows from the venous condition of the blood, ex- ternal stimuli are still capable of exciting respiratory movements. Engstrom found, too, that when the foetus had breathed in the amniotic sac, after respirations had ceased, and after the blood in the umbilical vein and arteries had become of the same blue color, and the nose and lips had become cyanotic, it was still possible to excite res- pirations in some cases by opening the amnion and lifting the head so as to expose it to the air, and in others by pinching the nostrils, the ears, and the mouth. For the sake of convenience, I shall take the liberty of recalling at this point the peculiarities of the fetal circula- tion. The arterialized blood in the umbilical vein empties partly into the portal vein, and is first distributed to the liver, and in part passes by the ductus venosus into the inferior vena cava. The mingled venous and arterial currents then enter the right auricle, and are in early pregnancy directed by the Eustachian valve across the right auricle to the left auricle, and thence pass to the left ventricle. As the heart contracts, the blood is driven from the left ventricle to the aorta, and is thence distributed by the large vessels which spring from the latter to the head and upper extremities. The blood returned from the upi)er portion of the body by the superior vena cava enters the right auricle, where it passes in front of the Eustachian valve to the right ventricle. With the advance of gestation, however, a gradual disappearance of the Eustachian valve takes place, so that a part of the blood from the in- ferior cava enters with that of the superior cava into the right ventricle. The contraction of the right ventricle forces the blood into the pul- g38 THE PATHOLOGY OF LABOR. monary artery, which distributes an insignificant quantity to the hmgs, while the main current passes through the ductus arteriosus to the aorta, by which it is distributed to the lower portion of the body. Now, though the greater part of the regenerated placental blood is distributed to the head and upper part of the body, it is mingled largely with venous blood returning from other organs, and that which goes to the respiratory center in the medulla oblongata is of a character which would cause dyspnroic manifestations in self-breathing individuals. During labor, especially in the last stage, the placental aeration of the blood is interfered with by the uterine contractions, and in its passage through the pelvis the surface of the child is subjected to pressure and friction. At birth the body is exposed to the air. These combined causes as a rule are followed by pulmonary respiration, though in some instances of lowered irritability of the medulla pro- longed apnoea follows the birth unless the child is made to cry by vigorous slapping. As the chest expands in the act of inspiration the lungs fill with air, and the blood from the pulmonary artery pours into the opened pulmo- nary vessels. The pressure in all the vessels of the body is diminished, though in the thorax a partial compensation takes place from the aspi- ration of blood from the veins which enter the intrathoracic sjDace. The diminution of .pressure is greatest in the pulmonary artery. The current which empties into the aorta becomes of feeble force, and final- ly ceases altogether. The ductus arteriosus gradually closes, and the pulmonary circuit becomes complete. The withdrawal of the blood from the pulmonary artery and the force of aspiration lower the tension in the aorta. The heart beats more slowly. The resulting diminished arterial pressure is most felt in the extremities. The pulsation of the umbilical arteries as a consequence ceases, and the placental circulation is suspended. In the asphyxia of new-born infants the suspended animation is, with few exceptions, preceded by intra-uterine respirations. The causes of the latter are to be found in tetanic contractions of the uterus and the consequent diminished blood-supply to the placenta, in premature detachment of the placenta, in compression of the cord, in acute anae- mia, and in the sudden death of the mother. Of these, the compres- sion of the cord is by far the most common. The first effect of the compression of the cord is to arrest the cir- culation in the umbilical arteries. The pressure in the aorta is thereby augmented, and increased work is thrown upon the left ventricle of the heart. Except in cases where the mouth and nasal passages are closed by pressure, with the expansion of the chest, due to the irritation of the medulla by the increased venosity of the blood, amniotic fluid, meco- nium, and mucus are aspirated into the air-passages. When the com- pression of the cord is temporary the circulation may be restored, and PROLAPSE OF THE FUNIS, ETC. 639 the apnoea may again return ; but in cases where the respirations con- tinue, the capilhiries of the kings fill with blood from the pulmonary artery, the intrathoracic venous congestion is increased, and the heart action is lowered. As the irritability of the medulla sinks, the res- pirations fail, the cavities of the heart fill with venous blood, the lungs are congested, and in some instances subpulmonary ecchymoses result from overdistention of the pulmonary vessels. Outside the thoracic cavity, the venous trunks are often distended with blood. This second- ary venous stasis is most marked in the vessels of the neck, head, and brain, but to a less degree venous stases are likewise observed in the abdominal organs and in the capillaries of the skin. Suspended animation may exceptionally occur without antecedent intra-uterine respiration. This is the case when disturbance or arrest of the placental functions takes place in foetuses so immature that their medullary centers can not respond to the irritation of insufficiently oxygenated disassimilative products by originating the nervous impulse necessary for the production of respiratory movements. Another cause of suspended animation unattended by intra-uterine respiration is, ac- cording to Schultze, a very slow progress of the placental respiratory dis- turbance, and a consequent gradual diminution of the amount of oxy- gen in the fetal blood. The deficiency in oxygen is at first so slight as not to stimulate the medullary center, and when the deficiency be- comes more marked, the irritability of the medulla has been so much depressed that it is no longer capable of originating a respiratory im- pulse. In this case the foetus dies or passes into a condition of sus- pended animation without having breathed at all.* Compression of the fetal brain due to a contracted pelvis, to intracranial haemorrhage, to the use of the forceps, f or to delivery in breech positions, may occa- sion death or suspended animation without exciting respiratory move- ments. The rationale of such cases is as follows : Cerebral compres- sion reduces or even arrests the heart's action by irritating the pneu- mogastric nerve. The placental respiratory function is thus impaired, the fetal blood is consequently deprived of oxygen, and the irritability of the medulla so reduced that the latter can no longer originate re- spiratory movements. J If intracranial extravasations are located upon, the convexity of the cerebrum, they are comparatively innocuous, since the medulla is not compressed. Their most pernicious effect is natu- rally observed when they are situated at the base of the brain. Morbid Anatomy. — Schultze recognizes two stages of suspended animation, which correspond to the terms asphyxia livida and pallida, usually employed to designate these respective conditions.** The * Schultze, op, cit., pp. 103 et seq. + DoHRN, Arch. f. Gynaek., Bd. vi. 1874. p. 365. X Frankenhauser, Monatsschr. f. Geburtsk., Bd. xv, 1860, p. 368. * Schultze, op. cit., pp. 6, 130, 147. u g^Q THE PATHOLOGY OF LABOR. boundary line between the two stages is marked by the loss, on the part of the muscles, of their tonic contractility. In the first stage the muscular tone is still jn-eserved. ' Although there are no spontaneous muscular contractions, the extremities are not completely relaxed, nor does the head drop. Reflex movements are easily produced by surface irritation. The skin is dusky red or cyanotic, the cutaneous vessels are turgid, the conjunctivae injected, and the eyeballs protruding. The cardiac and umbilical pulsations are slow but forcible. The umbilical vessels are fully distended. Respiratory movements usually occur only after a certain interval. They are at first feeble, superficial, and at- tended by facial contortions, but soon become more powerful. The increased deficiency in oxygen, occasioned by delivery, often furnishes to the medulla, in this stage of suspended animation, a stimulus of sufficient intensity to cause spontaneous respiratory movements. The same result is attained by irritation of the surface. If respiration does not ensue from either cause, the child passes into the second stage of asphyxia. In the second stage of suspended animation, or asphyxia pallida, the children are exceedingly anaemic. The conjuctivse are without luster; the surface is col^; the sphincters are relaxed; the limbs, head, and lower jaw hang loosely down. Reflex^moyements do not occur. The cardiac beats are frequent and, feeble. The umbilical pulse is almost or quite imperceptible. The umbilical vessels are empty. Either no spontaneous respiratory movements occur or they are few, snapping, and produced by the diaphragm, without the par- ticipation of the facial, nasal, or maxillary muscles. The respirations are ineffectual, since a post-mortem examination reveals little or no air in the bronchi, which are usually filled witli fluid matter, and since no rales are heard during the respiratory efforts. The medulla is so completely paralyzed that the stimulus of the increased deficiency in oxygen, attendant upon delivery, merely produces these futile respira- tory efforts. Should artificial means succeed in restoring the child, the first signs of its resuscitation will be refilling of the cutaneous capillaries and returning muscular tonicity. The morbid anatomical features of suspended animation vary according as that condition has or has not been attended by intra-uterine respiration. In the latter case the blood is dark and uncoagulated. The pulmonary vessels are widely distended. The lungs are enlarged, heavy, and of a dark-red color. Numerous pulmonary, subpleural subpericardial, and suben- docardial ecchymoses are present. The pulmonary extravasations are more extensive than in cases of asphyxia accompanied by intra-uterine respiration, for the reason that, in the latter, the aspirated fluids offer a certain support to the distended capillaries. Pulmonary congestion and ecchymosis may be absent if the inspirations were ineffectual, in- frequent, and of short duration. The obstruction of the pulmonary PROLAPSE OF THE FUNIS, ETC. 641 circulation further produces venous congestion of the surface, of the abdominal organs, and of the encephalon resulting in subconjunctival, meningeal, and cerebral hemorrhages. Ecchymoses may also be found beneath and upon the pericranium. Aside from the extrava- sated blood, no foreign matters are found in the bronchi. The absolute proof that the asphyxia of still-born children, or of those born in a moribund condition, was attended by iutra-uterine respiration consists in the discovery, within the bronchi, of substances introduced by tho- racic aspiration. When the proof is lacking, inspiration may still have occurred, but the entrance of foreign bodies has been prevented through occlusion of the nose and mouth by portions of the membranes, or by close appositian to them of the maternal soft parts. The quan- tity of aspirated material will depend upon its character and the force of the inspirations. The tough cervical mucus penetrates only to the trachea and primary bronchi. The liquor amnii, containing meconium, vernix caseosa, and blood and downy hairs, may even reach the ter- minal bronchioles. If air had found an entrance into the uterine cavity, it is also present in the bronchi, and, exceptionally, in the stomach and duodenum. The dilatation of the Eustachian tubes, as a consequence of the first inspirations, permits, in some instances, ac- cording to Wendt, * the penetration of liquor amnii into the middle ear. The pulmonary ecchymoses are less numerous and extensive in asphyxia attended by intra-uterine respiration than in the other va- riety, for reasons above stated, but congestion and extravasations in the abdominal and cerebral organs are quite as constant and important. Diagnosis. — An important diagnostic symptom of beginning as- phyxia is diminished frequency of the fetal he art-beat s, due to inhibi- tion of the placental respiration.. This has no significance if it be manifest only during the pains, since it is then a physiological occur- rence due to the mechanical compression of the foetus or to expression of the placental blood into the fetal vessels. If it persist, however, during the interval between the pains, and be jirogressive, it is of seri- ous import, betokening either considerable compression or irritation of the medulla by an excess of deoxygeuated blood. The diminished frequency is sometimes succeeded by increased rapidity of the cardiac contractions, indicating p.arah'sis^ of the pneumogastric, and, conse- quently, a more advanced stage of suspended animation, f This in- creased rapidity is, probably, invariably preceded by the diminished frequency of the heart's action already alluded to. The evacuation of meconium is also diagnostic of asphyxia, provided it be not merely the result of the mechanical compression exerted upon the child in breech presentations. The appearance of the meconium is, probably, due to the increased intestinal peristalsis attendant upon asphyxia, although, * Spiegelberg, Lehrbueh. p. 667. f HuTER, itloiiatsschr. f. Geburtsk., Bd. xviii, 1862, Supplem. Heft, p. 48. 41 g^2 THE PATHOLOGY OF LABOR. perhaps, in part occasioned by relaxation of the sphincters and com- pression of the abdomen by the contracting diaphragm. The dis- charge of meconium, accordingly, usually attends that form of sus- pended animation in which intra-uterine respiration has occurred, and is absent in those cases of gradually induced asphyxia unaccompanied by respiratory efforts. The differential diagnosis between these two varieties is completed, after delivery, by the detection of bronchial rales, due to the aspiration of intra-uterine fluids, in all cases of intra- uterine respiration except those in which the external air-passages were occluded. The discharge of meconium is sometimes not in- dicative of any pathological condition. Schultze * detected intra-uter- ine respiration by abdominal auscultation, as well as by intra-uterine palpation, and numerous observers have heard the vagitns uteriims, or intra-uterine cry, which bears testimony to the entrance of air into the uterus, and to the occurrence of respiratory movements, f When de- livery has been partially accomplished, the diagnosis of asphyxia is easily made from the failing fetal pulse, the cyanosis, the forcible re- spiratory efforts, and the relaxation of the child's muscles. Prognosis. — The prognosis depends largely upon the grade of the asphyxia, although the cause of the latter is of still greater signifi- cance. Suspended animation which is not accompanied by intra- uterine respiration offers the best prospects for resuscitation. The chances are smaller if inspiration has occurred, and the worst prog- nosis is afforded by the occurrence of resi:)iration when the nose and mouth are occluded, on account of the graver derangement of the fetal circulation, and the more abundant pulmonary extravasations. The presence of aspirated foreign substances clouds the j)rognosis by interfering with efforts at artificial respiration, and by acting as the exciting cause of atelectasis and of lobular pneumonia. The prognosis is also rendered grave by the occurrence of intracranial haemorrhages. The mortality of asphyxiated children in the first eight days after delivery is, according to Poppel's statistics,^ seven times greater tlian that of children born unasphyxiated, and the mortality in the first week in direct proportion to the duration and gravity of the sus- pended animation. Treatment. — The indications for treatment are in all cases to clear out the air-passages, to restore the i/ritability of the medulla, to in- crease the force of the heart-contractions, and to relieve the plethora of the heart and of the blood-channels of the thorax. In cases Avhere the muscular tonus is preserved these indications are, as a rule, easily fulfilled ; aspirated fluids and mucus should be cleared * Schultze, op. cit.. p. 127. t Kristeller, Monatsschr. f. Gehurtsk., Bd. xxv. 1865, p. 321 ; Baetschee, Ibid., Bd. ix, 1857, p. 294; Mayer, Ibid., Bd. xxv, 1805, p. 341. X PoppEL, op. cit., p. 57. PROLAPSE OF THE FUNIS, ETC. 643 from the fauces with the finger. If the nasal passages are obstructed, mouth-to-mouth insufflation should be employed. The child should be made to cry by flagellation, and the respiratory movements should be further stimulated by alternately immersing the child in hot and cold water. So far the procedure is a familiar one, but in a good number of cases we know that in a few days the skin becomes dusky, the heart action feeble, and the child has been temporarily restored to life only in the end to die of atelectasis. As a means of guarding against this fatal sequence, due in part to imperfect expansion of the lungs, in part to lobular congestion, there is no method that rivals the one of Schultze. Schultze directs that the child should be grasped in such a manner that the operator's thumbs rest, on either side, upon the anterior tho- racic wall, while the index-finger occupies the axilla, and the remaining fingers are placed diagonally across the back. The child is then al- lowed to hang at arm's lengtli between the knees of the obstetrician, its face being turned to the front. In this position the pectoral muscles are made to draw the superior ribs upward, the abdominal muscles draw the inferior ribs downward, and the weight of the liver causes the descent of the diaphragm. By this means the capacity of the chest is increased, and inspiration is produced. The child is next swung up- ward, until the arms of the operator reach an almost horizontal posi- tion. The swinging motion is then arrested, flexion occurs in the child's lumbar spinal region, its head is directed downward, and its lower extremities fall slowly toward the obstetrician until the whole weight of its body rests upon his thumbs. In this way the chest and abdomen are powerfully compressed, the diaphragm is forced upward, and an efficient expiration results, and any retained adventitious mat- ters are expelled from the air-passages. An inspiration is now pro- duced by reversing the direction of the swing and returning the child to its former position of complete extension, by which manoeuvre the chest is made to expand and the diaphragm to descend. By this method not only is good aeration of the lungs secured, but the forcible expiration expels the materials aspirated from the bronchial tubes. A still more important action, according to Schultze, is the re- lief of the overloaded vessels as a result of the compression of the entire thoracic contents. Thus, as expiration is produced by the upward swing, the blood is pressed from the left ventricle into the aorta, and from the right auricle into the right ventricle. The emptying of the left ventricle makes room for the contents of the left auricle, and per- mits the return current from the pulmonary veins. From the right ventricle the surplus blood finds a passage into the aorta through the ductus arteriosus. With the inspiratory swing blood is aspirated from the peripheral vessels into the blood-channels of the thorax. The as- pirated blood is, however, venous, as the semilunar valves prevent re- g^^ THE PATHOLOGY OP LABOR. gurgitation from the aorta. By alternating the expiratory and in- spiratory swinging movements the pump-working of the heart is mechanically set in action. As the blood-streams pass through the heart cavities, the systole increases in force and the arterial tension is restored. In cases of deep asphyxia, in which muscular tonicity is lost, and the heart movements are scarcely perceptible, the methods at first em- ployed should involve the minimum degree of disturbance to the child. Active movements are, as a rule, speedily followed by the extinction of heart pulsations. The child should be laid upon a table and covered warmly. After clearing the fauces and nasal passages a No. 8 English elastic catheter should be passed, under the guidance of the fingers of the left hand, through the larynx into the trachea, and aspirated matters should be carefully removed by suction. Meantime, at intervals insufflations through the tube into the bronchial tubes should be employed. After each insufflation the chest walls should be compressed with the hand, to produce expiration. By this means, little by little, the blood re- ceives oxygen, and the returning irritability of the medulla is mani- fested by occasional spontaneous respiratory movements. When the color returns to the skin, and the heart's action is restored, artificial respiration should be maintained, at first by means of Sylvester's method, which is preferable to that of Schultze in feeble children, as it involves less exposure and less violent manipulations. In Sylvester's method * the child is placed upon its back with the shoulders raised sufficiently to prevent the chin from falling forward on the breast. The tongue is drawn forward to maintain a free entrance of air into the windpipe. To imitate the movements of deep inspiration, the operator grasps the arms above the elbows, and, raising them upward by the sides of the head, he extends them gently and steadily upward and forward for a few moments. At the same time the feet should be fixed. According to Champneys, the effect produced is more than twice as great when the arms are everted as when the* arms are in- verted. This he attributes to the mode of insertion of the pectoralis major muscle into the outer lip of the bicipital groove, eversion natu- rally rendering this more tense. Expiration is effected by turning down the arms and pressing them gently but firmly against the sides of the chest. When the process has been repeated a few times, the warm bath should be employed to prevent undue refrigeration of the cutaneous surface.

In prematurely de- livered asphyxiated children these methods are inapplicable, since the thoracic walls are so yielding as not to undergo the changes of form requisite to the success of the methods described. In such cases insuf- flation, through the catheter, following aspiration, of the foreign bodies in the air-passages, is the oi^y available treatment. If the efforts at resuscitation be successful, the child must, for the first few days after its birth be kept particularly warm and be regularly nourished.* Collapse and Sudden Death during Labor and Childbed. We have already had frequent occasion to mention collapse during or following labor as a sequence of hemorrhage, or of injuries to which the genital passages have been subjected. Syncope is not an uncom- mon result of exhaustion following prolonged labor, or even normal labor in women with exceptionally sensitive nervous organizations. Again, it may be caused by the cerebral anaemia produced by the re- cession of blood from the nerve-centers when the intra-abdominal pressure is suddenly diminished by the rapid emptying of the uterus. Temporary syncope, if followed by complete restoration of the normal circulation, has no positive prognostic significance. Where, however, the pulse continues feeble and rapid, it should be, even in the ab- sence of other grave symptoms, a subject of profound concern. The arteries then gradually become empty, while the large venous trunks fill with blood, and the sluggish current predisposes to the formation of thrombi. Apart from such rare accidents as ceVebral apoplexy, or heart rupt- ure, or fatal endings from hemorrhage, from pulmonary congestions and oedema, from eclampsia, from inversion and rupture of the uterus, and acute septicaemia, the causes of sudden death are to be found in pulmonary embolism, in the entrance of air into the circulation, and in shock. On Thrombosis and Embolism. — Thrombi owe their importance to the disposition they possess to disintegrate and form emboli, which are swept along by the circulation until arrested by the diminished caliber of the peripheral vessels. A small clot forming in the left side of the heart may block up an artery in the brain or in either an upper or lower limb. The symptoms of the lesion in the latter case are the absence of pulsation in the artery below the thrombus, with pain, coldness of the surface, paralysis of the nerves of motion and sensibility if the * The substitution of Sylvester's method for those of Marshall Hall and Schroe- der, as given in the first edition of this work, is due to the very careful and satis- factory investigations of Francis Henry Charapneys in reference to the amount of ventilation secured by the dififerent methods of artificial respiration. (Med.-Chir. Trans., vol. Lxiv.) 646 THE PATHOLOGY OP LABOR. arterial obstruction be sudden and complete, and in some cases gan- grene of the extremity affected.* Of much more common occurrence are venous thrombi. Indeed, it may be stated that thrombosis of the veins furnishes the most fre- quent cause of sudden death in labor and during the puerperal period. As a rule, the clotting takes place in the femoral, the pelvic, or the uterine veins. Spiegelberg f states that the emboli which become de- tached during or shortly after labor proceed from clots formed at the site of the placenta. When the placenta is partially detached during labor, or the uterus does not properly contract after the birth of the child, sudden haemor- rhage, followed by syncope or marked weakening of the heart's action, may lead to the formation of large, soft clots, extending from the open mouths of the sinuses in the direction of the heart. These, by sudden movements, by the douche, or under a powerful contraction, such as oftentimes follows the rupture of the membranes or the expulsion of the foetus, may be set adrift from their moorings, and be washed up- ward through the vena cava to the right side of the heart, and thence to the branches of the pulmonary artery. It has been assumed, though not without question, that, owing to the large proportion of fibrin in the blood during pregnancy and child- bed, it is possible, when the heart's action is feeble, for spontaneous coagulation to take place in the pulmonary artery. This theory, originally broached by Meigs, has been warmly supported by Playfair and Barker. Clinically, many striking facts have been adduced in its support. Playfair argues that, when dyspnoea precedes phlegmasia doleus, the same causes which have led to throml)osis of the femoral veins have antecedently been at work in the formation of coagula in the pulmonary artery. But the post-mortem evidence of such a connexus is not conclusive. Dr. Mary Putnam Jacobi has reported the case of a patient, dying five hours after labor, where precordial oppression and dyspncea had been marked, and yet no lesions whatever were found at the autopsy to account for these symptoms. Nor is it possible, when we consider the frequency with which thrombosis of the uterine veins precedes that of the veins of the thigh, to be sure, in the absence of ^ post-mortem examination, that the dyspnoea observed by Pla^-fair may not have been due to an embolus from a clot formed in a uterine vessel. I would not, however, deny the possibility of Playfair's hypothe- sis. I only wish to emphasize the fact that, so far as the evidence goes, it lacks the positiveness of a scientific demonstration. According to all ordinary experience, the force of the blood-current in the pulmonary artery, except in the death agony, is sufficient to prevent spontaneous * Barker, The Puerperal Diseases, p. 257 ; Barnes, Thrombosis and Emboli of Lymg-in Women, Obst. Trans., vol. iv, p. 30. t Spiegelberg, loc. cit., p. 661. PROLAPSE OF THE FUNIS, ETC. 647 coagulation from taking place. Virchow has, however, pointed out that any of the few minor veins opening into the right auricle may be the seat of the primary thrombus, and give rise to a large secondary thrombus within the auricle. (Savage.) The symptoms of stoppage in a large pulmonary vessel are intense dyspno?a, air-hunger (to use an expressive German term), fluttering heart-action, a feeble, rapid pulse, a cold skin, and striking pallor of the countenance. Death may follow in a few minutes, or, where the main trunk is free, the more violent symptoms may in the course of a half-hour subside, to return, however, with the slightest movement or without apparent cause, the patient dying in a few days from abnormal lowering of the temperature, from dyspnoea, and cyanosis ; or, after a succession of attacks, the thrombus may be absorbed, and, as I have once seen, complete recovery may take place. The Entrance of Air into the Circulation.*— The passage of air from the uterine cavity into the circulation is rendered possible by the presence of open sinuses, or of sinuses closed by soft, easily detached thrombi. These conditions are always present previous to delivery in case of partial separation of the placenta, and in the puerperal state, especially in the latter, when, owing to debility resulting from the undue prolongation of labor, the expulsion of the ovum has been fol- lowed by imperfect retraction. Air may be forcibly driven into the uterus by means of the uterine or even the vaginal douche. For this veason the siphon syringe should be discarded from midwifery practice. The objection to the continu- ous stream furnished by a vessel placed at a height above the patient, based upon the insufficient force of the current, is purely theoretical. It is not necessary that the nozzle of the syringe should be intro- duced directly into the uterine cavity for accidents to occur. AVienerf has reported from Spiegelberg's clinic a case where collapse followed the use of the vaginal douche, though the tube was free from air, the hydrostatic pressure having forced air which had previously entered the vagina up into the uterus. When, therefore, the douche is employed to induce premature labor, the stream should at first be propelled gently, and the vulva should be parted to permit the egress of con- tained air. Less familiar than these cases of forced air injection are well- accredited instances of spontaneous entrance of air into the uterine sinuses. This accident is rendered possible by the diminution of the intra-abdominal pressure in certain body postures. Of these, the three familiar to us through gynaecological experiences are, respectively, * Vide Kezmarsky, Ueber Lufteintritt in die Bhitbahnen durch den puerperal. Uterus. Avch. f.

In child- birth, under favoring conditions, the sudden rupture of the membranes which had previously distended the vagina, or the rapid extraction of the child, may be followed by the ingress of air into the uterus itself, in some cases doubtless the recession of the uterus after its evacuation favoring the occurrence of the accident. The entrance of air into the uterus does, of necessity, do harm, or the harm may be limited to the production of endometritis; still there are recorded cases where the aspiration of air has been followed by almost instant death. The post-mortem examinations of cases of death from air entering the uterine sinuses show but little blood in the left side of the heart ; frothy blood from the cut surfaces of the uterus ; air in the uterine veins, the vena cava, the right side of the heart, and at the orifice of the pulmonary artery ; the lungs anaemic, and containing frothy serum ; the brain pale and infiltrated with serum. Corresponding to these anatomical conditions, the hands during life were cold, the pulse scarcely perceptible, the face blue and livid, consciousness was lost, and the respirations were labored and jerky, with all the symptoms of intense dyspna3a. Nerve Exhaustion and Shock. — Twenty years ago these pathological states played a conspicuous part in the etiology of sudden death during childbirth. Now the fashion has changed. Such terms as " nervous apoplexy " and " idiopathic asphyxia," which were employed as synon- ymous expressions, belong to an almost forgotten nomenclature. None the less the need remains to account for a class of cases in which death takes place without recognizable organic lesions. Instances of death attributed to heart paralysis are to be found in the collections of McClintock * and Mordret ; f but to these objections have been made, either that the post-mortem confirmation of the diag- nosis was lacking, or that the examination was lacking in the com- pleteness necessary to shut out other possible causes of death. Baart de la Faille, J however, has more recently collected thirteen cases of collapse in which the occurrence of embolism and the entrance of air could with every probability be excluded. Cases where the absence of all symptoms of pulmonary obstruction furnish certain evidence that neither of these causes was operative may be found scattered through medical literature.* In the absence of visible lesions, or the characteristic symptoms of the conditions to which death in childbed is usually referred, we have * McClintock, Dublin Med.

PROLAPSE OF THE FUNIS, ETC. 649 the right to attribute the melancholy issue to the same causes which, outside of childbed, produce identical phenomena. In the torpid form of shock the features are pinched, the eyes sunken and surrounded by dark rings, the skin possesses a marble pallor, the hands and lips are blue, the extremities are cold, sweat stands upon the brow, the pulse is thready and scarcely perceptible, while, in contrast to cases of pulmonary obstruction, the breathing, though it may be shallow, is not difficult or labored, and, in spite of the extreme prostration of the physical forces, the sphincters remain closed, and both consciousness and sensibility are preserved. Sometimes these earlier symptoms are followed by a stage of excitement in Avhich the face, with the exception of the mucous membranes, becomes reddened, the eyes grow bright, the patient becomes restless, complains of constant thirst, and bids her friends farewell in anticipation of speedy death ; but, in spite of the reviving color, the pulse continues too rapid to be counted, the skin never regains its normal temperature, and the hopes of speedy restora- tion to health are dashed by the gradual or sudden suspension of the beatings of the heart. Modern pathological investigation refers the phenomena of shock to a reflex paralysis of the vaso-motor, and especially of the splanchnic nerves, whereby the great mass of the blood is withdrawn from the sur- face, and collects in the trunks of the coeliac, the mesenteric, and the renal veins. Hence, the skin becomes cold, and is devoid of color save at the points where a bluish hue is imparted by the stagnant blood still lingering in the veins ; the muscles, deprived of blood, feebly respond to the impulses of the will ; the empty vessels of the brain explain the sluggish intelligence, the nausea, the vomiting, and the indifference of the patient ; and, finally, during the diastole, the heart, pale and con- tracted, receives but little blood, and the radial pulse fades to nothing- ness because of the corresponding small amount of fluid propelled dur- ing the systole into the arterial vessels.* From works on military surgery we learn that it is in the defeated army, among homesick soldiers, at the close of a wearisome war, after great exertions and deprivations, that shock is developed in its severest forms ; that the finer the organization, the more readily the manifesta- tions occur ; that they are promoted by sudden losses of blood, and are in a special degree evoked by abdominal injuries. It certainly would be singular if similar conditions in childbed were not followed by similar results. After labor, the nervous system of the woman is depressed by pain, starvation, and loss of sleep. The sud- den emptying of the uterus is followed by a recession of blood from the head to the venous trunks of the abdomen. Haemorrhage, followed by weakening of the heart's action, tends still further to increase the venous stasis. In the old days of torture, shock often mercifully put * Fischer, Ueber den Shok, Volkmann's Sararal. klin. Vortrage, No. x. Q^Q THE PATHOLOGY OF LABOR. an end to the victim's anguish. Women in childbirth are at times subjected to pain exceeding that of the rack and the thumbscrew ; and the wonder is not that the circulation should occasionally show signs of marked and even fatal disturbance, but that the nervous system, at- tacked from so many directions, should, in the rule, triumph over the adverse forces. Treatment. — The treatment of pulmonary embolism, whether due to air or a disintegrated thrombus, is necessarily for the most part pro- phylactic. The proper precautions for avoiding the accidents described are sufficiently indicated in the preceding discussions as to their etiol- ogy. It is proper to remember that the nervous organization of woman loses in powers of resistance as the penalty of a higher civilization and of artificial refinement, and that it becomes, therefore, imperatively necessary for the physician to guard her from the dangers of excessive and too prolonged suffering. Especially I would raise my voice in warning against the current opinion that the length of the first stage of labor before the rupture of the membranes is a matter of indiffer- ence. In pulmonary embolism the violence of the symptoms at the outset of the attack is often out of proportion to the real gravity of the lesion. A small embolus or air entering the lungs, finely subdivided, may produce symptoms of dyspnoea which may be of temporary dura- tion. In all cases, therefore, warmth should be applied to the surface, and every effort should be made to maintain tiie action of the heart. To this end injections of ether beneath the skin, and of ammonia into the veins, are to be counted as most powerful adjuvants. In shock, opium, atropia, and digitalis are theoretically indicated, and yet large doses of the latter drug, as have been sometimes recommended, are not unattended with risk, and may precipitate the final catastrophe. Extraction of the Child in Case of Real or Apparent Death OF the Mother during Pregnancy or Labor. Death of the mother during pregnancy or labor may be threatened, or may actually result, either suddenly or slowly, from various morbid conditions which have been previously considered. Although sudden death of the mother is more frequent at the time of delivery, in con- sequence of haemorrhage, exhaustion, eclampsia, or rupture of the ute- rus, it may occur at any time, particularly when due to pulmonary and cardiac affections, or to cerebral embolism. It is our present object to consider the methods of treatment best adapted to the preservation of the child's life in those cases necessa- rily attended by death of the mother, and to the preservation of both mother and child whenever there is any probability of such a result. Our inquiry may therefore be limited to those cases in which the child is unquestionably living, and its viability undoubted. While the PROLAPSE OF THE lUNIS, ETC. 651 majority of recent authors upon this subject have recognized the pro- priety of adopting prompt measures for the immediate extraction of the child after the mother's decease, the same unanimity has not pre- vailed either in regard to the propriety of operative interference before the mother's death, or as to the most appropriate methods of opera- tion. Schroeder * is content with the statement that, in case of ma- ternal demise during parturition, efforts should be made to extract the fa3tus per vias nafnrales by version or the forceps. In the event of failure to accomplish delivery by this method, he advises immediate re- sort to the Caesarean section. SiDiegelberg f recommends the Caesarean section for all cases of maternal death, excepting those occurring in the second stage of labor, as the surest method of preserving fetal life. He makes no provision for those cases in which the mothers are appar- ently dead, although actually in a state of syncope or asphyxia. Both he and Max Runge J recommend the Cesarean section, even in cases of impending death of the mother, in the child's interest, and dispar- age efforts at extraction through the natural passages. Duer ^ con- cludes («) that no operative procedure should be undertaken until there is absolute certainty of the mother's death ; (b) that, death of the mother being assured, the Caesarean section should be performed with dispatch if the fetal head be above the pelvic brim ; (c) that, if the head have engaged in the brim, the question of resort to the Ca?sarean section or to extraction ^^er vias nafnrales becomes debatable. He condemns the practice advocated by Rizzoli and Esterle, of resorting to forced de- livery when the mother's death is imminent. One of the most recent and comprehensive articles on the subject of artificial delivery jper vias naturales is that of Thevenot,|| who, re- ferring its original introduction to Schenk and Eigaudeaux, and its development to Rizzoli, Heymann, and Depaul, ardently advocates its adoption, to the exclusion of the Cesarean section. This method he declares to be applicable {a) to those cases with normal pelvic confor- mation in which the mother is dead, the labor somewhat advanced, the OS dilated or dilatable, and the head at the superior strait ; {h) to cases in which labor was only commencing, or had not begun at the time of death ; (c) to cases frequently occurring, according to the author, of apparent death of the mother (her real condition being that of syn- cope), whether labor had or had not begun at the time of her apparent decease ; and {d) to cases of impending maternal death.

Thevcnot cites fifteen cases of accoucliement force employed upon women at the point of death, in which thirteen infants were alive at birth, and six lived permanently. Five of the fifteen mothers, who were apparently mori- bund, recovered, and in three other cases the original diseases were re- tarded, and their most distressing symptoms temporarily relieved. Tympanites Uteri. — If air enters the uterine cavity previous to the birth of the child, the dangers are not confined to its passage into the venous circulation. Even when this latter accident does not occur, the patient's condition in a lingering labor is perilous in the extreme. The essential condition for the admission of air is rupture of the mem- branes. As a result in many though not in all cases untimely re- spiratory efforts are excited in the child. In very rare instances it is said that the cry of the child, vayitus uterinus^ has been heard within the nterus. Death speedily follows premature respiration, and, under the combined influence of air, heat, and moisture, decomposition rapidly develops. * The gases generated by putrefaction are some- times of enormous volume, and the uterus furnishes a tympanitic resonance upon percussion. As a result of prolonged labor, of the dis- tention of the uterine walls, and of septic poisoning, the pains become feeble and the patient suffers from dyspnoea, owing to the pressure upon the diaphragm by the enlarged uterus and the colon, which like- wise is found distended with gases. A stinking discharge, sometimes mingled with gas-bubbles is always present. The prognosis depends upon the intensity of the process and the length of time allowed to elapse before operative measures are em- ployed to remove the source of danger. Of sixty-four women, accord- ing to Staude's report, thirty-two died, eighteen had severe puerperal affections, and only fourteen recovered without further complications. The indications for treatment are, to extract the child as soon as prac- ticable when air has once entered the uterine cavity, to wash out the uterus with disinfectant fluids, to use all available means to secure continued retraction of the uterus, and follow every antiseptic pre- caution during the puerperal period. * Staude found putrefactive changes developed in foetuses born from three to twenty-one hours after the access of air to the uterus.

Definition. — Puerperal fever is an infections disease, due, as a rule, to the septic inoculation of the wounds which result from the separation of the decidua and of the placenta, and from the passage of the child through the genital canal in the act of jaarturition. To maintain this definition it is, however, necessary to group by themselves cases of childbed fever dependent upon causes which are operative in the non-puerperal condition, though the latter imparts to those causes oftentimes an exceptional activity and virulence. In this category are to be placed especially scarlatina, typhus, typhoid, and ma- larial fevers. It is to be borne in mind that the zymotic fevers may pro- voke in the puerperal woman the same inflammatory lesions commonly associated with puerperal fever.* This is in accordance with the well- known surgical experience that a febrile paroxysm from any cause exerts an unfavorable influence upon a wounded surface. Like all brief statements, the writer is well aware that the foregoing definition is necessarily imperfect, and stands in need of further lim- itations to meet the requirements of exactness. Exceptions, however, either apparent or real, will be noted hereafter in their proper connec- tions. Frequency. — In a careful search through the records preserved by the Health Department of New York city, I found that from 1868 to 1875, inclusive, the total number of deaths for nine years was 248,533. Of these, 3,342 were from diseases complicating pregnancy, from the accidents of child-bearing, or from diseases of the puerperal state ; or, in other words, 1 : 75 of all the deaths occurring during that period was * Hervieus, Traite clinique et pratique des maladies puerperales, pp. 1073 etseq. g^j. DISEASES OF CHILDBED. the result of the ijerformance of what we are in the habit of regarding as a physiological function. The deaths from miscarriage, from shock, from prolonged labor, from instrumental delivery, from convulsions, from hasmorrhage, from rupture of the uterus, and from extra-uterine pregnancy, and deaths from eruptive fevers, from phthisis, and from inflammatory non-puer- peral affections complicating childbirth, made a total of 1,395, or about 42 per cent of the entire number. The remaining 1,94:7 cases, vari- ously reported as puerperal fever, puerperal peritonitis, metro-peritoni- tis, phlebitis, phlegmasia dolens, pyaemia, and septicemia, represent the very serious sacrifice of life resulting from inflammatory processes which have their starting-point in the generative apparatus. If we apply the general term puerperal fever to this class of cases, it will be seen that the yearly average of deaths between the years mentioned was 215 -5, and that the malady was the cause of nearly one one-hundred-and- twenty-seventh of all the deaths occurring in the city. More recently statistics have been prepared for me from the same sources by my friend Dr. Rutson Maury for the five years from 1885 to 1889, inclusive, which show that the reported deaths from puerperal sepsis were 1,105, or an annual average of 221. The population of New York in 1870 was 942,292 ; in 1875, 1,1G9,- 305 ; in 1885, 1,553,730 ; in 1890, 1,755,292, It will be seen, therefore, that the ratio of deaths has by no means kept pace with the increase of the city's population. A portion of this betterment is doubtless attributable to reforms in the management of our lying-in hospitals. "Whereas, formerly these institutions furnished nearly one sixth of the fatal cases of puerperal sepsis, they now, when properly equipped and organized, afford the safest places of refuge for parturient women. There has likewise been, without doubt, an improvement in results among the well-to-do classes. Among these there is a widely diffused belief that puerperal fever is a preventable disease, and that for its occurrence tlie physician should be held responsible, and this leads to greater painstaking on the part of the latter, even when he is disinclined to accept the deductions from mod- ern scientific teaching. Among the poor, in their own homes, I do not believe that the dangers of childbed have been perceptibly lessened, for in Dr. Maury's statistics it appears that even in the past five years one tenth of the deaths in women between the ages of fifteen and forty-five are due to causes connected with childbirth, and that one twentieth of the deaths among women in the child-bearing period are due to puer- peral sepsis. Max Boehr,* in his now-famous statistics, reckons that one thirtieth of all married women in Prussia die in childbed. The Puerperal * Untersuchungen iiber die Haufigkeit des Todes im Wochenbett in Preussen, Zeitschr. f. Geburtsk. und Gynaek, vol. iii, p. 82. PUERPERAL FEVER. 655 Fever Commission* appointed by the Berlin Society of Obstetrics and Gynaecology arrived at the conclusion that from 10 to 15 per cent of the deaths occurring in women during the period of sexual activity were due to childbed fever, and that this disease destroyed nearly as many lives as small-pox or cholera. But puerperal fever differs from either small-pox or cholera in that the latter presses largely upon the aged and the very young, while the former gathers its victims exclu- sively from a selected class — viz., from women in adult life, the moth- ers of families, whose loss, as a rule, is a public as well as a private calamity. Before proceeding to consider the nature of puerperal fever, it is desirable to first recall the anatomical lesions with which it is associated. These, it will be found, are for the most part inflammatory processes, having their starting-point in injuries of the genital passage produced by parturition, complicated in many cases by septic changes in the blood, by secondary degeneration of parenchymatous organs, and at times by phlegmonous and erysipelatous affections in remote as well as in the ad- jacent serous and cutaneous tissues. Morbid Anatomy. — The primary lesions connected with puerjjeral fever are so various that the student will find it convenient to classify them according as they are situated in the mucous membrane of the utero-vaginal canal, the parenchyma of the uterus, the pelvic cellular tissue, the peritonasum, the lymphatics, or the veins. Not, indeed, that such an arrangement is strictly in accordance with clinical expe- rience — as a rule, the inflammatory processes are rarely limited to a single tissue — but because the prognosis and treatment are determined in great measure by the tissue-system which is predominantly affected. The significance of puerperal inflammations, wherever seated, likewise depends upon whether they are local and circumscribed or whether they present a spreading character. Personally, I have found the following classification, based on that of Spiegelberg,f of great utility as a means of keeping in mind the principal points to Vv'hich inquiry should be directed in estimating the significance of the febrile conditions of childbed : 1. Inflammation of the genital mucous membrane. — Endocolpitis, endometritis, and salpingitis. a. Superficial, suppurative. h. Ulcerative (diphtheritic). 2. Inflammation of the uterine parenchyma, and of the subserous and pelvic cellular tissue. a. Exudation circumscribed. b. Phlegmonous, diffused ; with lymphangitis and j)ya3mia (l3'm- phatic form of peritonitis). *Zeitschr. f. Geburtsk. und Gynaek, vol. iii, p. 1. f Ueber das Wesen des Puerperalfiebers, Volkmann's Samml. klin. Vortr., No. 3, 656 DISEASES OF CHILDBED. 3. Inflammation of the peritonaeum covering the uterus and its appendages. — Pelvic peritonitis and diffused peritonitis. 4. Phlebitis uterina and para-uterina, with formation of thrombi, embolism, and pyaemia. 5. Pure septicsemia. — Putrid absorption. Endocolpitis, Endometritis and Salpingitis.— In the superficial sup- purative form of inflammation the mucous membrane of the vagina is swollen and hypertemic, the papillae are enlarged, and the discharge is profuse ; in the vaginal portion of the cervix the labia uterina are oedematous and covered with granulations Avhich bleed at the slightest touch ; in the cavity of the body there are increased transudation of serum and abundant pus-formation. The deep structures of the uterus are usually not affected. Sometimes the inflammation extends to the tubes — scdpingitis — or, passing outward through the fimbriated ex- tremities, it may spread over the adjacent peritonaeum. The small wounds at the vaginal orifice are at times converted into ulcers with tumefied borders. These so-called puerperal ulcers are covered with a grayish-white layer. They are associated usually with oedematous swelling of the labia. Under favorable sanitary conditions the layer, which consists in the main of pus-cells and necrosed tis- sue, is thrown off, and the surface heals by granulation. The ulcera- tive form of inflammation is very rare outside of crowded hospitals. Diphtheritic ulcers are situated with greatest frequency in the neighborhood of the posterior commissure, or around the vaginal ori- fice. In rarer instances they are found upon the anterior wall and in the fornix of the vagina, in the cervix, and upon tlie site of the pla- centa. The borders are red and jagged ; the base is covered with a yellowish-gray, shreddy membrane ; the secretion is purulent, alkaline, and fetid ; and the adjacent tissues are cedematous. From the vulva they may extend to the perinteum, or pursue a serpiginous course down the thighs. In the uterus and about the cervix they vary as re- gards size, and are either of a rounded shape or form narrow bands. The intervening portions of tissue which have not undergone destruct- ive changes swell and stand out in strong relief. Where the entire inner surface has become necrosed, it is often covered with a smeary, chocolate-brown mass, which, when washed away with a stream of water, leaves exposed either the deepest layer of the mucous membrane or the underlying muscular structures. Not infrequently the inflammatory process extends to the tubes, which swell and become tortuous. The tubal canal fills with pus, or in diphtheritic forms, with a fetid, brownish, ichorus material. The dis- tention is most marked at the ampulla?. Usually the fimbriated ex- tremities of the tubes are closed by adhesive inflammation. Sometimes, however, they remain patent, and permit the purulent secretion to spread over the adjacent peritonaeum. PUERPERAL FEVER. 657 Metritis and Parametritis. — In ulcerative endometritis, and even in the extreme suppurative form, the parenchyma of tlie uterus likewise becomes involved. The changes which are designated under the term metritis consist, in the first place, of oedematous infiltratiou of the tis- sues. As a consequence, the organ contracts imperfectly and becomes soft and flabby, so that sometimes, upon post-mortem examination, it bears the imprint of the intestines. In diphtheritic endometritis, the destructive process may attack the muscular tissue, and give rise to losses of muscular substance — a condition known as necrotic endometritis or putrescence of the uterus. Inflammatory changes are rarely lacking in the intermuscular con- nective tissue, which exhibits, in j^laces, serous or gelatinous infiltration, with, afterward, pus-formation, and with here and there small abscesses. The sero-purulent infiltration of the connective tissue is specially marked beneath the peritoneal covering of the uterus either behind or along the sides at the attachment of the broad ligaments. In the same situations the lymphatics, which normally are barely perceptible to the naked eye, are sometimes enlarged to the size of a quill, and are characterized by varicose dilatations occurring singly or presenting a beaded arrangement. In the substance of the uterus the dilated ves- sels are liable to be mistaken for small abscesses. The pus-like sub- stance contained in the lymphatics is composed of pus-cells and of micrococci. From the cellular tissue surrounding the vagina, or that beneath the peritoneal covering of the uterus, the inflammation may spread by contiguity of tissue between the folds of the broad ligament, and thence pass upward to the iliac fossae. Usually the process is uni- lateral. After the inflammation has crossed the linea terminalis it may take a forward direction, above the sheath of the ilio-psoas muscle, to Poupart's ligament, or it may creep upward, following the course according to the side affected, of the ascending or descending colon, to the region of the kidney. It is rare for inflammation of the cellular tissue to travel around the bladder to the front. In such cases it pur- sues its course between the walls of the bladder and the uterus, and along the round ligament to the inguinal canal. In a few cases the cellulitis mounts above Poupart's ligament, between the peritonaeum and the abdominal wall. The course of the inflammation is not simply fortuitous, but fol- lows prearranged pathways in the connective tissue. Konig* and Schlesinger f have shown that when air, water, or liquefied glue is forced into the cellular tissue between the broad ligaments the injected mass has a tendency to invade the iliac fossae. In Schlesinger's ex- periments, if the canula of the syringe was inserted into the anterior * Arch, fler Heilkunde, 3 Jahrg., 1862. t Gvnaekologische Studien, No. 1. 42 g^g DISEASES OF CHILDBED. layer of the broad ligament, the glue spread between the folds to the abdominal end of the Fallopian tube ; thence, following the track of the vessels, it passed to the linea terminalis ; and finally mounted up- ward along the colon or swept forward to Poupart's ligament, until the advance wjis stopped at the outer border of the rotind ligament. If the injection was made to the side of the cervix through the posterior layer at the junction of the cervix and the body, the posterior layer gradually bulged out, the peritonaeum was lifted from the side wall of the pelvis, and the glue passed beyond the vessels to reach the iliac fossa. If the injection was made to the side of the cervix through the anterior layer, the glue passed between the bladder and the uterus, and forward along the round ligament to the inguinal canal, while another portion of the fluid passed between the layers of the broad ligament, and reached the peritoneal covering of the side walls behind the round ligament. If the injection was made in the m^edian line, in a peritoneal fold of Douglas's cul-de-sac, the fluid traveled forward upon one side along the round ligament, and thence to the posterior wall of the bladder. The term parametritis, introduced into use by Virchow, is, proper- ly speaking, limited to inflammation of the connective tissue imme- diately adjacent to the uterus, the older one of pelvic cellulitis furnish- ing a more comprehensive designation for cases where, as a consequence of a progressive advance from the point of departure in the genital canal, the remoter regions have likewise been invaded. Connective- tissue inflammation presents, as the first essential characteristic, an acute cedema, the fluid which fills the gaps and interspaces consisting of transuded serum rendered opaque by the presence of pus-cells or pos- sessing a gelatinous character. In the mild, uncomplicated cases, the oedema disappears rapidly. Where the cell-collections are of mod- erate extent, the entire process may vanish without leaving a trace of its existence. If the cell-elements, on the other hand, are present in great abuadance, they, as a rule, first undergo fatty degeneration, and, after the absorption of the fluid portion, form a hard tumor composed of a fine granular detritus, which under favorable circumstances like- wise, after a few weeks, becomes absorbed. In rare cases, abscess-for- mation in the tumor results. In the cellulitis resulting from the more intense forms of septic infection, and especially when complicated by diphtheritis, the tissues seem as if soaked with dirty serum, and contain scattered yellowish deposits, which soon present, even to the naked eye, the appearance of pus-collections. This sero-purulent cedema is always associated with lymphangitis, the lymphatic vessels possessing varicose dilatations and beaded arrangements similar to those already described in the uterine tissue. The foregoing changes are most distinct in the firm connective tissue adjacent to the uterus and at the hilum of the ovary, while they PUERPERAL FEVER. 659 are less clearly traced in the loosor structure of the broad ligament (Spiegelberg). In favorable cases the infliimmation is circumscribed, or at least is limited, by the nearest lymphatic glands. In cases of more severe in- fection it spreads rapidly, and justifies the title bestowed upon it by Virchow of parametritic malignant erysipelas. Pelvic and Diffused Peritonitis. — Inflammation of the pelvic peri- toui^um may proceed from severe attacks of catarrhal endometritis, the inflammatory process either traversing the uterine tissue or passing through the Fallopian tubes to the adjacent serous membrane ; in cases of cellulitis it may follow the penetration of pus corpuscles and coccus forms through the lymphatic intersjiaces and between the endothelia into the peritoneal cavity. As a rule, pelvic peritonitis is not attended with much exudation. The latter is situated upon the folds of the peritongeum limiting the cul-de-sac of Douglas, upon the ovaries, and upon the broad ligaments. In favorable cases it consists of fibrinous flakes and fluid pus. If the latter is abundant, it may become encysted by the formation of adhe- sions between the pelvic organs. General peritonitis may result from the extension of a pelvic perito- nitis, from the introduction of infectious materials into the abdominal cavity as a consequence of rui)tures of the uterus or vagina or of per- foration of walls of pus collections, whether contained in the tubes or in the pelvic cavity, or from the transport of poison through the lym- phatics into the peritoneal sac. In the first cases, which are character- ized by the formation of pus and fibrin, the intestines are distended and the diaphragm is pushed upward. The process begins with capil- lary injection of the peritonaeum, with exudation upon the dejDcndent portions of the abdominal space, and with the appearance of leucocytes about the vessels and in the exudate. This is followed by fibrinous exu- dation upon the intestines, which unites them loosely together. The endothelial cells of the abdominal sac swell and their nuclei multiply ; later, the exudate increases and becomes purulent or watery, but is al- ways mixed with fibrin. The enlarged endothelial cells strip off, the peritoneal and intestinal walls swell and are infiltrated with leucocytes and cells from the division of the connective-tissue corpuscles. By a continuance of this process granulation tissue is produced, which unites adjacent tissues. The watery constituents of the exudation are then absorbed, or pus collections persist, surrounded by pyogenic membranes. These encysted collections may undergo caseous changes or become ichorous, or may perforate into an intestine, the bladder, the vagina, or through the navel. In the so-called peritonitis lymphatica the inflammatory symptoms are at the outset lacking. The abdominal cavity is found filled with a thin, stinking, greenish or brownish fluid composed of serum and micrococci. g^Q DISEASES OF CHILDBED. The intestines are lax and cedematous, and tlie muscular structures are paralyzed, with the resulting tympanitic distention. The peritoneal covering of the intestines is devoid of luster and covered with injected patchest or is stained of a dark-brown color. Death often ensues be- fore the occurrence of exudation. Septic forms of pelvic inflammation are often associated with oophoritis, the dilated lymphatics either extending to the substance of tlie ovaries, where they may lead to the production of small abscesses, or, as a result of blood dissolution, the organs become soft, pulpy, and infiltrated with discolored serum, and present haemorrhagic spots dis- tributed over the surface. Phlebitis and Phlebo-thrombosis.— The formation of throml)i in the uterine and pelvic veins is sufficiently common during the puerperal period. The coagulation may result from compression or from enfee- blement of the circulation. A predisposition to its occurrence is created by relaxation of the uterine tissue. A normal thrombus is in itself harmless. In time it becomes organized, and the occluded vessel is converted into a connective-tissue cord, or a channel may form through it which permits the passage of the blood-stream. When, however, septic microbes obtain access to a thrombus, it undergoes rapid disin- tegration, and the particles get swept away into the circulation until arrested in the ramifications of the pulmonary artery. Wherever these poisoned emboli happen to lodge, inflammation is set up in the adjacent tissues, and abcesses result (pya?mia nniltiplex). Sometimes countless collections of pus may form in the lungs. Less commofily abscesses are found in the liver or spleen, originating either from emboli which have already made the pulmonary circuit, or from thrombi in the i)ulmonary veins. Inflammation of the veins (phlebitis) sometimes occurs when the ves- sels have to traverse tissues in or near the uterus infiltrated with puru- lent or septic materials. The endothelium then undergoes prolifera- tion, and thrombosis is produced. Phlebitic thrombi do not necessarily break down, and may in that case act as a barrier to the progression of septic germs into the circulation (Spiegelberg). As a rule, however, under the influence of inflammation and infection, they become con- verted into puriform masses. The thrombi grow by accretion in the direction of the heart. They may extend from the uterus through the internal spermatic, or through the hypogastric and common iliac veins, to the vena cava. Sometimes the thrombus may be traced back to the placental site. Septicaemia. — From these local conditions, sooner or later, secondary affections develop in distant organs. The general affection is, in great part at least, likewise of local origin. Sometimes, however, where the poison, which enters tlie system through the lymphatics and veins, is very active and abundant, death may follow from acute septicaemia PUERPERAL FEVER. 661 before the changes in the sexual organs have had time to develop. The fatal result, in these cases, is probably due to paralysis of the heart. After death, jmst-moi'tem decomposition rapidly sets in, the blood is sticky, and swelling is found in the various parenchymatous organs. The secondary affections consist in the metastatic abscesses already noticed as produced by infected emboli, in circumscribed purulent collections due to the conveyance of septic materials into the blood- current through the lymphatics, in ulcerative endocarditis, in inflam- mations of the pleura, the pericardium, and the meninges, and in purulent inflammation of the Joints. Saprsemia (Putrid intoxication). — This term was invented by Matthews Duncan to apply to the fever which results from the absorp- tion into the blood of sepsin and the ptomaines, the products of putre- faction, in distinction from the febrile forms due to the entry into the circulation of bacteria capable of reproduction. In saprsemia the fever and general symptoms rapidly disappear when the source of poison supply, usually the uterine cavity, has been washed clean and thoroughly disinfected. A study of the nature of puerperal fever will best show how inti- mately these seemingly distinct processes are linked together. Earlier Views concerning- the Nature of Puerperal Fever.* — Ac- cording to the teachings of Hippocrates, Galen, and Avicenna, of Ambrose Pare, of Sydenham, and of Smellie, the fevers of puerperal women were attributable to the suppression of the lochia. For twenty centuries this doctrine was accepted almost without dispute, the best clinical observers confounding a symptom which is often lacking with the cause of the disease itself. In 1686, Puzos f taught that milk, circulating in the blood, is at- tracted to the uterus during pregnancy and to the breasts after con- finement, but tliat milk metastases may form in other parts, and produce the symptoms of malignant or intermittent fever. In 1746 A. de Jussieu, Col de Villars, and Fontaine advanced in support of this theory the fact that they had found, on opening the abdomen in women who had died from an epidemic which raged that year in Paris, a free lactescent fluid in the lower portion of the abdominal cavity and clotted milk adherent to the intestines. This doctrine, which seemed to be based upon, and to accord with observation, found many adherents in France. It lost ground, however, when, in 1801, Bichat pointed out the true nature of the abdominal effusions of women who had died in childbed, and demonstrated that they were to be found likewise in peritoneal inflammations occurring in men and in non- puerperal women. * For data given, and for a great variety of historical information, vide Her- viEux, Traite clinique et pratique des maladies puerperales. f Premier memoire sur les depots lacteux. QQ,2 DISEASES OF CHILDBED. While, during the second half of the eighteenth century, the doc- trine of milk metastasis held full sway in France, in England and Germany the dominant leaders in medicine referred the causes of puerperal fevers to inflammations of the womb and of the pei'itonaium. With the advances made in pathological anatomy in the beginning of the present century, France taking the lead, stress was likewise laid upon inflammations of the veins and of the lymphatics. The vitality of the doctrine of local inflammations is well shown by the records kept by the Health Board of this city, where a large proi)ortion of the deaths returned from childbed fever are entered under the head of metritis, of peritonitis, of metro-peritonitis, and of puerperal phle- bitis. In opposition to the doctrines of the so-called localists, the theory that puerperal fever is an essential fever, and as much a distinct dis- ease as typhus fever, typhoid fever, or relapsing fever, has been strenu- ously advocated by some of the most distinguished clinical teachers who have devoted their attention to obstetrical science. Fordyce Barker, in his classical work upon the Puerperal Diseases, states the arguments against the local origin of tlie diseases as follows : 1st, that puerperal fever has no characteristic lesions ; 2d, that the lesions which do exist are often not sufficient to influence the progress of the disease or to explain the cause of death ; 3d, that there may be inflammation, even to an intense degree, of any of the organs in which the principal lesions of puerperal fever are found, and yet the disease will lack some of the essential characteristics of puerperal fever ; 4th, that the lesions are essentially different from spontaneous or idiopathic inflammations of the tissues where these lesions are found ; 5th, that puerperal fever is often communicable from one patient to another through the medium of a third party, and that this is not the fact in regard to simple inflammations in puerperal women. However, neither Barker nor those who entertain views similar to his question the local origin of many febrile affections in childbed, but claim that purely local inflammations have each their characteristic symptoms, which differ from those of true puerperal fever ; tliat puer- peral fever is a zymotic disease of unknown origin ; and that local lesions, where they coexist, are not the primary source of trouble, but are secondary to changes in the blood. In 1850 James Y. Simpson* published a short paper On the Analogy between Puerperal and Surgical Fever. This article may well be regarded as the foundation of the modern doctrine concerning puer- peral fever, and is well worthy of perusal at the present day; for, though in the then existing state of pathology many of the links were wanting which have since raised the argument to nearly a mathemati- cal demonstration, the paper furnishes a brilliant example of the * Edinburgh Medical Journal. PUERPERAL FEVER. 663 scientific foresight wliicli is able to discern the truth even where tlie evidence lacks completeness. In 1847 Semmelweis, who was at that time clinical assistant to the Lying-in Hospital at Vienna, made the startling assertion that " puer- peral patients were chiefly attacked with puerperal fever when they had been examined by the physicians who were fresh from contact with the poisons engendered by cadaveric decay ; that fever ensued in the practice of those who, after post-mortem examination, washed their hands in the usual manner, whereas no fever or but few cases of disease followed when the examiner had previously washed his hands in a solu- tion of chloride of lime." In the face of insult, ridicule, and abuse Sem- melweis maintained this position for years, almost unaided, with fanatical persistency. It was easy for his opponents, for the most part man- agers of the great lying-in asylums, to show from clinical experiences the weakness of so one-sided a theory. But the employment of the equivocal demonstration /r/Z^-Ms in nno,faIsus in omnihns, served only as a temporary defense against the laxity which prevailed in hospital management only a quarter of a century ago. Though Semmelweis died with no other reward than the scorn of his contemporaries, it is impossible at the present day to so much as contemplate the abuses he attacked without a shudder. In 1800 Semmelweis published the result of his ripened experience in a treatise entitled Die Aetiologie, der Begriff und die Prophylaxis des Kindbett-fiebers, in which, abandoning his earlier exclusive posi- tion, he maintained that puerperal fever arises from the absorption of putrid animal substances, which produce first alterations in the blood, and secondly exudations. He distinguished between cases in which the infection was introduced from some external source, and which he believed to be the most frequent variety, and those where the poison was generated in the system. The sources from which the infection is derived he believed to be — 1st, from the dead body, regardless of age, sex, or disease, no matter whether the latter is of puerperal or non- puerperal origin, the virulence depending upon the stage of decom- position ; 2d, diseased persons, whose malady is associated with decom- position of animal tissue, no matter whether the affected person suf- fers from childbed fever or not, the decomposing matter alone furnish- ing the product from which infection is derived ; 3d, physiological animal substances in the process of decomposition. As carriers of infection, he regarded the fingers and hands of the physician, midwife, or nurse, sponges, instruments, soiled clothing, the atmosphere, and, in brief, anything which, after being defiled with decomposing animal matter, was brought into contact with the genitals of a woman during or subsequent to parturition. Absorption takes place from the inner surface of the uterus or from traumata in the genital canal. Infection seldom occurs in pregnancy, because of the closure of the os internum, QQ^ DISEASES OF CHILDBED. the absence of wounded surfaces, and because of the rarity with which examinations are made; during dilatation infection is common, but exceptional during the period of expulsion, because the inner uterine surface is at that time rendered inaccessible by the advance of the child; in the placental and puerperal period infection occurs from utensils and instruments, but chiefly through the access of atmospheric air when the latter is loaded with decomposing organic matter. In rare instances, auto-infection may result from spontaneous decomposi- tion of the lochia, of bits of decidua, of coagula of blood, of necrosed tissue, or in consequence of severe instrumental labors. In a v/ord, puerperal fever was, according to Semmelweis, no new specific disease, but a variety of pyemia. The Nature of Puerperal Fever as regarded from the Standpoint of Modern Investigation. — The older beliefs in the suppression of the lochia and the metastases of milk have long since been relegated to the domain of old nurses' lore, and do not call for serious discussion. The localist theory, that puerperal fever is a metritis, a peritonitis, a phle- bitis, or an inflammation of the lymphatics, is, as mortuary records show, still adhered to by many practitioners, and, as we have seen, is Justified by the fact that puerperal fever is, with rare exceptions, asso- ciated, at some period of its progress, with certain inflammatory pro- cesses which have their starting-point in the generative apparatus. But the localist theory leaves out of view the existence of blood-poison- ing, and yet the coexistence of a blood-poison with the local lesions is an essential feature of puerperal fever. It was this defect which gave to tlie advocates of the specificity of puerperal fever their real impor- tance. Modern investigation has, however, proved that the puerperal poison is septic in character, and that puerperal fever is really a surgical fever, modified, however, by the peculiar physiological conditions which belong to the puerperal state. Thus, it has been found that, in the human subject, and in expari- ments made upon animals, septic poisons introduced into the system following or near delivery produce lesions similar to those found in puerperal fever. As a further coincidence, it has been noticed that, as in puerperal fever, the lesions from direct septic poisoning have nothing characteristic about them, producing in one case pyaemia, in another partial peritonitis, in another general peritonitis, in another diphtheritis, while in others the lesions are comparatively trivial, these differences being due to variable facta, such as the qualities of the septic poisons, the points of entry into the organism, and the resistance offered by the invaded tissues. There is one experimental point of extreme practical importance in connection with puerperal septicaemia— viz., that if the injection of a septic fluid be made directly into a vessel, toxic effects speedily follow, but are transitory, unless the amount of the fluid be large, or its viru- PUERPERAL FEVER. 665 eq 93 0,0 oo CO cB- ip CO Co CD oo 8§ "^^ A Po oo PQ I >- ^ Z ^ Q X! ^^ •o CS " 2 h( s ;^ Oj r O O D.

In other words, the eliminating organs sufUce, under ordinary conditions to re- move from the blood an amount of septic fluid which would prove fatal if injected into the tissues. To produce similar results the injections into the blood need to be repeated at intervals. This experience leads us to the conclusion that, in the tissues, septic poisons possess the capacity of self-multiplication, and that from the local inflammation set up a supply is formed from which poisonous matter is continuously poured into the circulation. The capacity of self-multiplication with which septic materials are endowed has been found to be the property of certain parasitic bodies termed bacteria. The prevailing pathogenic organisms in puerperal- fever cases, according to the researches of Doleris, consist of bacilli or rods, and of micrococci in the varieties of monococci or single points; of diplococci, double points; and of streptococci or chain and wreaths. Staphylococci are sometimes found in parametritic abscesses, or even in the uterine cavity. It is conceded, however, that the stre2)tococci are the important factors in the production of infection. Without entering upon diflficult and unsettled questions concerning the manner in which disease germs accomplish their destructive work during the puerperal period, it may be stated that, in the first place, they generate, as one of their vital functions, toxic substances which kill the tissues, excite inflammations, produce fever, and give rise to nervous disorders. The bacilli are the agents of putrefaction. Their action is local. They attack dead tissue only (clots, bits of placenta, shreds of mem- brane, portions of decidua). They do not themselves invade the tis- sues. The products of putrefaction contain certain poisons termed ptomaines, which when they enter the circulation, cause a general in- toxication. AVhen the offending substances are removed from the uterine cavity, the systemic symptoms disappear. The instinct which prompts the employment of the disinfectant douche in cases where there is a stinking lochial discharge is a sound one, but it is a common clinical observation that in many cases the symptoms continue thereafter unabated, and that, likewise, in severe and even in fatal forms of puerperal fever the lochia are free from odor. True infective puerperal fever has no direct connection with putre- factive organisms. It is the product of the streptococci, which not only are in themselves highly poisonous, but possess the faculty of PlaU IK Microscopic Sections in Puerperal Endometritis. (Bumm.)

It is surmised that when they are thus associated, the putrid endometritis excited by the one furnishes a con- genial soil which favors the multiplication of the other. DESCRIPTION OF PLATE IV.

Arborescent distribution. Earely the streptococci pass from the uterine cavity by the Fallo- pian tubes to the periton.eal sac. This probably only happens when the tubes have been rendered patent by antecedent disease. In many instances the action of the streptococci is confined to the inner surface of the uterus. In these cases and in those of ordinary putrid endome- tritis a layer of leucocytes forms next to the necrosed tissues which acts as a w^all to prevent the penetration of the germs into deeper-lying structures. In the event of general infection, this barrier has been feebly developed, and was easily broken through by the invading host. In the lymjihatic form of septicaemia tlie streptococci pass, sometimes, through the narrow gaps between the muscular fibers to the peritoneal surface of the uterus, or, more frequently, they enter the canalicular spaces in the connective tissue forming the framework of the genital canal which is continuous with subperitoneal connective tissue of the pelvis. From the canalicular spaces they enter the lymphatics. Cel- lulitis is excited by their presence, and the lymphatic glands become inflamed and enlarged. In the walls of the uterus the lymphatics are, in places, found distended with cocci, which excite inflammatory processes in the neighborhood followed by necrosis of the muscular structures, by migration into the softened tissue of masses of leucocytes, and by the formation of small sequestered abscesses (Bunim).* In pernicious forms they produce a sero-purulent oedema, which spreads rapidly with a wave-like progress after the manner of erysipe- las ; or, in milder cases, the progress of the disease germs is arrested by * BuMM, Histologische Untersuchungen ueber die puerperale Endometritis. Arch, f. Gynaek. Bd. xl, pp. 398 et. seq. gg3 DISEASES OP CHILDBED. the lymphatic ghiuds or the resistance offered by the tissues themselves, and the ordinary circumscribed phlegmon is produced. By the lym- phatics which accompany the vessels of the Fallopian tubes they reach the ovaries (puerperal ovaritis), and by the broad ligaments they pass to subperitoneal tissues of the iliac and lumbar regions. Through the same system they are conveyed to the great serous cavities of the body. In the peritontfium they give rise, unless death occurs too speedily, to pya3mic peritonitis, which, unlike the traumatic form, is attended with but little pain. The wide stomata upon the abdominal surface of the diaphragm allow the facile entrance of the organisms into its lym- phatics. Waldeyer found, in diaphragmitis, the lymphatics of the dia- phragm filled with bacteria. And thus, following the lymphatic sys- tem, the frequency, in severe types of puerperal fever, of inflammation of the serous membranes of the peritoufeum, the plural, the pericardi- um, the meninges, and the Joints finds an easy explanation. Nor is it altogether accident which determines in different cases the precise serous membranes which are affected. The widespread ramifications of the lymphatic system would naturally give rise to eccentric inflammations in place of those following the apparent continuity of tissues. When the streptococci infect wounds about the vulva and in the va- gina the resulting process is apt to be local unless the germs possess an unusual degree of virulence. As regards their effect upon wounds of the cervix, the question is still open to debate, but here, too, it is prob- able that the tendency is to the formation of circumscribed inflamma- tions. The streptococci are detected with difficulty in the blood during life. A few hours after death they swarm in that fluid. That they do, how- ever, enter the general circulation during life is incontestable. Steurer writes : " As the kidneys are the great filters of the human system, I never neglected to examine them, and almost invariably found micro- cocci filling the arterioles and glomeruli." This is in correspondence with what occurs in other septic diseases, and accounts for the albumi- nuria and interstitial nephritis which often supervene in the advanced stages. They are likewise found in the liver and in the spleen. Doleris assures us that in puerperal fever, by repeated trial, especially after a chill, he has never failed to demonstrate their presence in the circula- tion. They do not, however, multiply in the blood during life. AVhen they come in contact with the red corpuscles, the corpuscles stick to- gether and form larger or smaller clots in the blood. They then are no longer able to pass through the minute capillary networks, but are arrested in the vessels (Koch). The micrococci in the resulting infarc- tions multiply and migrate into the vessels and cellular tissue of the neighborhood. Thus fresh foci of infection are formed. Or, by their destructive action they may, when situated near the serous surfaces, penetrate into the serous cavities, and in this way indirectly occasion PUERPERAL FEVER, 669 peritonitis, pleurisy, memngitis, and purulent inflammations of the joints. When the micrococci enter directly into the circulation they sometimes, in passing through the heart, adhere to the endocardium and the valves, where they cause exudation and ulceration, and give rise to the so-called endocarditis ulcerosa puerperalis. The red globules of the blood undergo changes of shape, assume a stellate aspect, and rap- idly disappear. The white globules are greatly increased in numbers, and the blood itself becomes nearly colorless. A certain amount of light is thrown upon these blood changes by Doleris, who added mi- crococci to the fresh blood of a frog and watched the ensuing changes under the microscope. The micrococci could be seen in the act of pen- etrating the red globules, which thereupon lost their color and became shrunken, and, following the discharge of the organisms, which mean- time had multiplied in an astonishing manner, little or nothing of the original globules remained. The thrombotic form of infection has been studied by Bumm in the veins which spring from the placental site. He found that the migra- tory movements of the cocci from the endometrium followed the axis of the thrombus, and thence spread outward toward the vein walls. The latter then became infiltrated with round cells, which quickly made their way into the canal of the vessel. A disintegration of the clot was associated with these occurrences, and thus the vessel became filled with a detritus composed of leucocytes, of parasitic organisms, and of the debris of the thrombus. In other instances, according to Doleris, micro- cocci derived from the blood are deposited upon the central extremities of the clots ; beyond these depots a fresh inflammation is set up, fol- lowed by fibrinous coagulation. Thus the micrococci become impris- oned between two plugs. The same process may be repeated until a series of abscesses is formed. For a time no mischief may ensue- Finally, however, the resistance of the outworks is overcome, an embo- lus becomes detached, and an infectious abscess is opened into the blood — an event which is announced by an intense chill and the familiar sys- temic derangement. In septic diseases death takes place from apncea, partly from the inability of the blood-corpuscles to carry oxygen to the tissues — and partly from paralysis of the nerve centers. In estimating the susceptibility to sepsis in the puerperal state it is necessary to take into account the blood changes induced by pregnancy, the effects of shock and exhaustion in protracted labors, the frequency of haemorrhage, the deep situation of puerperal wounds, the presence of clots, decidua, and dead tissue in a state of disintegration or decom- position, the ease with which deleterious matters are absorbed by the wide lymphatic interspaces, the serous infiltration of the pelvic tissues, the exaggerated size of the lymphatics and veins, and the proximity of the peritoneal cavity. Q^Q DISEASES OF CHILDBED. Samuel,* in speaking of the immunities and dispositions to septic poisoning, says : " The statistical frequency of septic puerperal dis3ase is due tothe length of the parturient canal, to the fact that through this long passage there must pass all the pathological and physiological excretions, and to the soiling of these parts with fingers, instruments, and secretions which have become the bearers of sepsis." He found, on the other hand, that it was extremely difficult to produce a progress- ive ichorous condition by daily painting an open stump with a septic fluid,t though the same was readily obtained when an infinitesimal quantity of septic fluid was injected underneath a fascia. We have seen that when septic organisms are introduced into the uterine cavity there are individual difi'erences in the ensuing results. Thus, in many cases, their action is limited to the production of local inflammatory troubles and to self -limited systemic disturbances, while in others they overcome all resistance and lead to the most far-reaching changes in the blood, in the circulatory apparatus, in the parenchyma- tous organs, and in the serous cavities. The reason for these differences are to a certain extent a matter of conjecture. It is, however, admitted that the virulence of disease germs may be modified by culture experi- ments, or by seemingly accidental conditions. Bumm maintains that what is termed virulence is an acquired power of bacteria to withstand the destructive influences upon them of the saps and tissues, and to multiply within the living body. That the innate powers of resistance to morbific agencies differs in individuals seems probable. Kehrer re- minds us that, before the antiseptic period, it was not uncommon for a practitioner fresh from an autopsy upon a puerjieral woman who had died of lymphatic peritonitis, to examine patients in labor with hands which had been simply washed in soap and water, and that of the women thus infected a certain number had violent or even fatal forms of sepsis, while others were scarcely perceptibly affected. Doubtless, when the uterus is firmly contracted, the clots in the orifices of the placental veins are small, and the invasion of cocci is hindered by the compression of the lymphatic sj^aces, and vice versa. With a flabby, re- laxed uterus, the soft thrombi and the widely dilated absorbents furnish favorable conditions for the spreading of infection. While insisting upon the septic character of puerperal fever and its association with the presence of streptococci, it is not pretended that inflammations of the pelvic organs in childbed may not proceed from other causes. Indeed, I have myself witnessed cases where peri- tonitis has seemingly started from old intraperitoneal adhesions, or was secondary to ulcerative processes in the caecum or the descending colon. I am inclined, likewise, to agree with Genzmer and Volk- *Ueber die Wirkung des Fiiiilniss-Processes auf den lebenden Organisraus. Arch, f. exp. Pjithologie. vol. i, p. 343. t Loc. cit., p. 339. I PUERPERAL FEVER. 671 maun * tliat there is such a thing as an aseptic surgical fever due to the absorption of the products of physiological tissue-changes at the seat of injury. In surgical cases, even where the precautions of Listerism have been faultlessly observed, febrile movements of considerable in- tensity, but of no prognostic signification, are of frequent occurrence. AVhile, in puerperal women, we can never exclude the possibility of the septic infection of puerperal wounds, it is in accordance with clinical experience to assume that a higli fever belonging to the aseptic class may coincide with a septic process of insignificant proportions. General Symptoms. — As in other infectious diseases, there is, from the time of the entry of the poison into the system up to the outbreak of fever, a distinct period of incubation. The first febrile symjDtoms usually occur within three days of the birth of the child. An attack coming on a few hours after childbirth is indicative of infection dur- ing or previous to labor. The third clay is the one upon which, ordi- narily, the beginning of the fever is to be anticipated. After the fifth day an attack is rare, and at the end of a week patients may be regarded as having reached the point of safety. Apparent exceptions to this rule are j^robably referable to cases of mild parametritis, in which the initial fever and the pain were insufficient to attract attention to the existence of local inflammation. The symptoms of puerperal fever vary with the character of the local afCections, and with the extent to which the general system par- ticipates in the disturbed action. The different groups of j^uerperal processes possess the following pathognomic symptoms — viz., increased temperature, enlargement of the spleen, disturbed involution, and sensitiveness of the uterus upon pressure (Braun). In most cases, the fever is ushered in by chilly sensations or by a well-defined chill. This symptom, however, does not possess much prognostic importance. A chill is significant of a sudden change be- tween the temperature of the skin and that of the surrounding me- dium. It may, therefore, be absent in pernicious forms of fever, pro- vided only that the temperature changes are inaugurated slowly, whereas it may follow a trifling increase of the body heat if, as some- times happens in sleep, the moist skin is exposed to cool currents of air. Eepeated chills indicate phlebitis and pyaemia. In order to grasp the many symptoms of puerjoeral fever it is neces- sary to keep separately in mind the clinical features of each of the local processes, although in fact the latter rarely occur singly, but to a greater or less extent in combination with others. The Symptoms of Endometritis and Endocolpitis.— The uncompli- cated catarrhal inflammation of the uterus and vagina is the most fre- quent and the mildest of the diseases of childbed. In endometritis the * Genzmer and Volkmann, Ueber septisches und apeptisches Wundfieber, Samml. klin. Vortriige, No. 131. 672 DISEASES OF CQILDBED. uterus is large, flabby, and sensitive upon pressure ; the after-pains are often unusually severe, involution is retarded, and the lochia become fetid, remain sanguinolent for a longer period than usual, and at the outset may be temporarily suspended. Sometimes the large intestine is distended with flatus. In endocolpitis the vaginal discharge is thin and purulent, the patient experiences pain and burning in the acts of defecation and urination, and, where the wounds of the vulva and vao-ina assume an ulcerative character, there is often found at the same time inflammatory oedema of the labia. The fever in these cases is ushered in frequently, but not always, by chilly feelings, and the tsmperature reaches its height usually upon the evening of the third or fourth day, is remittent, almost intermit- tent in character, and rarely exceeds 102° to 103° Fahr. In mild forms the occurrence of the fever is often overlooked, or is referred to dis- turbance produced by the secretion of the milk. In severer attacks the febrile symptoms may continue from three to seven days. At the end of a week the swelling of the labia subsides, the discharge becomes thick, and ulcers, if present, begin to assume a healthy granulating appearance. In diphtheritic ulcerations, and in endometritis due to decompos- ing remains of the ovum, the local condition is often complicated by the invasion of the neighboring tissues. The Symptoms of Parametritis and Perimetritis (Pelvic perito- nitis *). — The symptoms of these two alfeetious, as would be naturally expected from the proximity of the peritonaeum to the pelvic con- nective tissue, for the most part overlap. It must be very rare for one form to occur entirely independent of the other. For this reason it will be found convenient to consider first the symptoms common to both morbid processes, and subsequently to direct attention to what are believed to be points of distinction between them. During the period of incubation there are usually no prodromic symptoms Elevations of temperature in the course of the first twelve hours following labor are equally frequent under perfectly normal con- ditions. Suspicious symptoms are disturbed sleep, excessively painful after-pains, and a pulse of 80 to 90. The beginning of the fever occurs, in 90 per cent, within the first four days of childbed ; most frequently upon the second or third day, and taking place upon the fourth day in scarcely 12 to 15 per cent of the cases. If five days have elapsed without fever, the period of dan- ger, with very rare exceptions, may be regarded as having passed. At the outset the fever, especially in perimetritis, is ushered in by * The following clinicjil history, together with the statistical details, is borrowed in great part from the description of Olshaiisen (Ueber puerperale Parametritis und Perimetritis, Volkmann's Samml. klin. Vortr., No. 28), the exactitude of which 1 have had abundant opportunity to verify. PUERPERAL FEVER. 673 chilly sensations or by an intense chill. The temperature rises rap- idly, though the highest point is usually not reached before the sec- ond, and in rare cases not before the third day. In most cases, the heat in the axilla exceeds 103°, and may even mount up to 105°. The decline occurs gradually, the fever ending in 70 per cent in the course of a week, in 20 per cent in two weeks, and only in 10 per cent ex- tending beyond that period. Protracted cases indicate abscess formation. The fever does not, however, always pursue a regular course. In place of progressively declining until the termination is reached, the high temperature of the second day may be attained upon one or more occasions. The morning remissions are at first slight, but become marked as the disease approaches its close. In cases of long duration the morning hours are often free from fever, a circumstance calculated to mislead a physician who sees his patient but once a day. A pulse of 80 to 90 beats, a disturbed sleep, lack of appetite, and sensitiveness to pressure upon the sides of the uterus are, however, symptoms which should serve as a warning of some disturbing cause, and should lead the physician to renew his visit in the latter part of the day. If, from a mistaken notion that the morbid process has come to an end, the patient is allowed prematurely to resume her household duties, the pains across the abdomen and along the hip and thigh return, and an examination reveals the existence of exudation in the pelvic cavity or upon an iliac fossa. Errors of this kind are most frequent in cases of parametritis as- sociated with slight peritoneal inflammation, as the local pain is then insignificant, and the initial chill, happening on the third or fourth day, is apt to be ascribed to engorgement of the breasts. Relapses after the complete disappearance of febrile disturbance occur in 15 to 20 per cent. They are usually shorter, but sometimes more obstinate, than the original attack. As a rare exception may be mentioned cases with evening remissions and morning exacerbations. In circumscribed pelvic inflammations the pulse rarely exceeds 120 beats to the minute. A pulse of 140, of more than half a day's dura- tion, betokens severe septic complications, and is therefore of evil omen. In some cases the slow pulse observed after labor makes its influence felt in the first day or two of the fever, so that the curious phenomenon may be witnessed of a temperature of 104° coinciding, for a time, with a pulse ranging between 50 and 70 beats to the minute. As regards other symptoms, headache and sleeplessness are rarely absent. Profuse sweating follows the first febrile attack, and frequent- ly recurs during the course of the disease. Pain is present at the onset in the majority of cases, and is then usually most violent. The spontaneous pain, which is due to the affection of the peritonaeum, subsides in great part in the course of one or two days, but the sides of the uterus remain sensitive to pressure. 43 Q^^ DISEASES OF CHILDBED. In the rare cases of pure parametritis, however, this symptom may be absent altogether. The pain, like that from the inflammation of serous membranes, is of a lancinating character. Sometimes it is asso- ciated only with the contractions of the uterus. After-pains occurring under unusual circumstances, as in primipara? or after the third day, are to be regarded with suspicion. Vomiting occurs occasionally, but is comparatively rare, unless the peritonitis becomes diffused and spreads to the region of the stomach. The appetite is lost, and only returns, as a rule, with the departure of the fever. The tongue is coated and moist, and constipation is com- mon. In other cases there is diarrhoea, with rumbling in the bowels, but without pain or tenesmus. The urinary secretion is rarely inter- fered with, and, when this is the case, it indicates the extension of the inflammation to the peritoneum covering the bladder. Most cases of perimetritis and parametritis terminate in five or ten days, the fever and other symptoms gradually subsiding. When, as may happen in exceptional instances, the temperature falls suddenly from a high degree to one below the normal level, the body grows icy cold, the pulse becomes small and irregular, and symptoms of collapse develop. But, in twelve to twenty-four hours, the symptoms of collapse subside, and the disease reaches its end with a disappearance of the alarming manifestations. If the fever subsides within a week, exudation is somewhat rare. Its continuance beyond that date should lead to a careful exploration of the pelvic organs. The exudation is usually demonstrable in the course of the second week or at the beginning of the third week. It is recognized, according to its location, by external or by internal ex- amination, or, where the deposit is considerable, by both methods. In many cases the deposit is extra-peritoneal, and is situated between the folds of the broad ligament, above and to the sides of the vaginal cul-de-sac. It has generally a rounded form, though with less con- vexity than fibrous and ovarian tumors. Sometimes, however, the tumor is flat below, like a board. It seldom exceeds in size that of a large apple. In fresh exudations the sensation produced is often that of a hard tumor surrounded by a softer layer, due to continued succu- lence of the soft parts. In a few weeks they may reach or exceed tlie hardness of a fibroid tumor. The older the tumor, unless suppuration sets in, the less sensitive it becomes. Often the exudation extends to the pelvic walls. The uterus, as a rule, is fixed, and, in cases of large tumors, becomes pushed toward the opposite side, while, as a conse- quence of later shrinkage,, the fuudus may be drawn permanently toward the affected side. The cul-de-sac of the vagina is rendered broader and flatter by the pressure of the deposit, or, Avhen the tumor is deep enough, the vagi- nal surface may be rendered convex. Behind the uterus the exudation PUERPERAL FEVER. 675 is, as it were, flattened antero-posteriorly, and in some cases it may be felt in tlie form of rigid bands between the posterior ligaments which inclose the cul-de-sac of Douglas. The ante-uterine tumors have a spherical shape and depress the vagina anteriorly. Tumors situated in the iliac fossa have a more or less convex form, and may be of such considerable size that the swelling may be recog- nized by the eye through the abdominal walls. As the exudation be- tween the broad ligaments may, in these cases, have been slight from the beginning, or may have subsequently disappeared by absorption, the iliac tumors have often, apparently, a spontaneous origin. Sometimes the uterus is surrounded by exudation, and the entire pelvis appears as though it were a mold filled with a solid mass. The fornix is then often pressed downward, and irregular rounded massed are to be felt through the vaginal walls. The recognition of parametritic tumors through the abdominal coverings is possible when they are situated above Poupart's ligament, in the upper portion of tlie broad ligaments, and in the iliac fossae. Unquestionably many supposed parametritic tumors have been really cases of salpingitis with accompanying intraperitoneal deposit of lymph. The pain and the functional disturbances in the pelvic organs de- pend upon the size and situation of these inflammatory deposits. Of the functional troubles, may be mentioned frequent and painful mic- turition, obstinate constipation and difficult defecation, contractures of the ilio-psoas muscles when the exudation is seated beneath the sheath or between the muscle and the pelvic bones, disturbances of motility in the abductor muscles, paresis of the lower extremities, and radiating pains in the upper portion of the thigh and in the renal and lumbar regions, produced by pressure upon the obturator, the crural, the cutaneous, and the sciatic nerves. So long as fever is present, the exudation rarely diminishes. If ab- sorption takes place in one point, growth almost certainly follows in some other direction. When, however, the apyretic period is reached, the exudation, as a rule, disappears rapidly, so that often in the course of six weeks no trace of its existence remains. In a smaller number, the solid mass may persist for months or even years. After the fever has departed the patient usually feels well. The sleep and appetite return, the night-sweats disappear, the pulse often falls to 50 or 60 beats, and the temperature is in many cases, for a time, subnormal in character. Where the fever persists for from five -to six weeks, there is always a suspicion of abscess formation. With the exception of afternoon fever and night-sweats, the patient may feel very comfortable. Then the exudation becomes sensitive, the spontaneous pains recur, sleep is lost, and locomotion, defecation, and urination occasion acute suffer- ere DISEASES OF CHILDBED. ing. The fever becomes violent, chills announce the presence of pus, and finally, about the seventieth or eightieth day, perforation of the abscess takes place. The usual seat at Avhich the pus is discharged is Just above Poupart's ligament ; next, in frequency, perforation takes place into the colon, and in rare instances into the bladder, the uterus, and vagina. Fortunately, of very rare occurrence is the discharge of pus into the peritoneal cavity, which is naturally followed by acute peritonitis. Another likewise unfrequent but most dangerous acci- dent is the septic infection of the abscess — an occurrence referred by Olshausen to the diffusion of intestinal gases through the Avails of the tumor. In suppuration of parametritic exudations the pus commonly forms in small scattered collections, and rarely gives rise to large abscesses. Although parametritis and perimetritis are usually found associated together, there are always cases in which the one form of inflammation so far predominates over the other as to justify an attempt to establish a clinical distinction between them. In the beginning of the attack, sharp pain, high fever, and tym- panitic distention of the lower abdomen are symptomatic of inflamma- tion in the pelvic peritonaeum. AVhether the cellular tissue is simul- taneously implicated can only be determined by a digital examina- tion after the abdominal sensitiveness has subsided. The absence of the objective signs of cellulitis would then contribute to prove that the case had been one in which the peritonaeum had l)een in the main affected. On the other hand, moderate fever, pain elicited only on pressure, and tympanitic distention confined to the colon, coinciding with exudation between the folds of the broad ligament, would be in- dicative of a nearly pure cellulitis. A palpable exudation is by no means the necessary product of peri- toneal inflammation. Indeed, in many cases, the distinctive symptoms of the latter may be present for from four to eight days, and may then subside without leaving a trace of its existence at the pelvic brim. The demonstration of a fluid effusion by noting the change of level, upon shifting the position of the patient, is rarely possible, either be- cause the quantity is too small or because it quickly becomes confined by pseudo-membranous adhesions between the intestines. Bandl * mentions as a sign of local peritonitis, sometimes notice- able, a number of resistant points or tumors near the pelvic brim or above one of the iliac foss«, due to a matting together of the intestines or to their adhesion to the uterine appendages. They are distinguished from solid tumors by their emitting a tympanitic sound upon percus- sion, and by their changing position in consequence of an accumulation of urine in the bladder or of faces or gases in the bowels. Again, all tumors may be reckoned as intraperitoneal which very rapidly form * Handbuch der Frauenkrankheiten, red. von Billroth, 5ter Abschnitt. PUERPERAL FEVER. 677 behind or to the side of the uterus from inclosed exudation-products, and which at the same time rise far above the level of the pelvic brim. If, however, they- start from the cul-de-sac of Douglas, and do not much exceed the linea terminalis, or if they occupy an iliac fossa, it becomes very difficult to decide whether they are of intra- or extra- peritoneal origin. The peritoneal exudation, however, long remains soft and fluctuating. It arises, as a rule, behind the uterus, and does not exhibit a tendency to spread to the sides or to the anterior or pos- terior pelvic walls. Still more difficult is it to decide as to the seat of exudations met with beneath the abdominal walls. When diffused and continuous with a pelvic deposit, the diagnosis is uncertain. It is only safe to as- sume the peritoneal origin of extravasations of a rounded form, of a fluctuating consistence, and when they are situated high uj) and are disconnected from exudation at the pelvic brim. An opening of the abscess through the navel would indicate a peritoneal source, while the discharge through the abdominal parietes would point to a seat in the connective tissue. After the perforation of an abscess, the fever and pain subside ; the wound, if external, either closes in the course of one or two weeks, or fistulas form which become the source of protracted suppuration. In psoas abscesses, the exudation extends beneath the sheath of the muscle or between the iliacus and the bone. In puerperal patients, they proceed from an inflammation originating in the broad ligament. They are situated too deep to be easily palpated. The pains they occasion are referred rather to the hip or knee than to the abdomen. The contracture of the psoas muscle furnishes a diagnostic sign which distinguishes this form from the superficial abscesses of the iliac fossa?. The pus eventually is discharged beneath Poupart's ligament, in the lower portion of the inguinal fossa, at some point upon the crest of the ileum, or exceptionally along the thigh. Often the discharge is main- tained for months. The Symptoms of General Peritonitis (Suppurative). — This form generally begins with the usual symptoms of pelvic inflammation, but the tenderness, which at first was limited to the side of the uterus, grad- ually spreads over the entire abdomen. The abdominal pain is of a tearing, lancinating, sometimes colicky character. It is increased by the slightest bodily movement, by jarring of the bed, or even by the weight of the bedclothes. As a consequence of the peritoneal inflammation and of the ac- companying exudation, the muscular walls of the bowels become para- lyzed, and tympanitic distention results from the accumulation of gases. In the dependent portions of the peritoneal cavity it is often possible to demonstrate, by percussion, the presence of fluid exudation, though distinct fluctuation is rarelv to be made out. The size of the abdomen g/j.g DISEASES OF CHILDBED. is due much more to the tympanites than to the amount of effusion. Sometimes the liver, with the diaphragm, is pushed by the swollen bow- els to the level of the fourth or third rib, and exercises such a degree of compression upon the posterior portion of the lungs as to place the patient in danger of suffocation. The respirations are jerky and at- tended with a moaning sound. The loss of muscular power in the intestines permits the contents of the middle portion to pass unchecked toward the duodenum, and thence, upon accidental contractions of the abdomen, tliey may jjass to the stomach and be ejected by vomiting. The first vomited matter has a dark-green color, and that ejected afterward presents the color of in- testinal matter. Constipation at the outset may be subsequently fol- lowed by colliquative diarrhoea. The fever begins, as a rule, though not always, with an intense chill, the temperature rises to 104°, and the pulse becomes small, hard, and resistant. Its frequency rapidly increases, varying from 1"^0 to KiO beats to the minute. The skin is sometimes dry, sometimes drip])ing with perspiration. In fatal cases, as the end approaches, the tempera- ture frequently falls, while tlie pulse becomes more rapid, the face as- sumes a pinched, anxious exjjresrfion, sweat gathers upon the foreliead, the extremities grow icy cold, and the patient dies in collapse. The duration of peritonitis averages not more than from four to six days. In cases of recovery the pulse imi)roves, the vomiting ceases, and the tympanites disappears. The diffuse exudation tlien becomes con- verted into circumscribed tumors, which, on palpation, are felt on the side of the pelvis and extending upward to the level of the umbilicus. Upon internal examination, the uterus is often found (lej)ressed by tiie weight of the fluid, which likewise may bulge the nd-de-sac of Douglas into the pelvic cavity. Sometimes the exudation may ]>ecome encysted above the pelvis and leave the contents of the latter free. In still otiier cases, the uterus may become attached high up to the abdominal walls, so that the vaginal portion disappears and tlie os is reached with diffi- culty. The peritoneal exudation may, as in pelvic inflammations, become absorbed and disappear. When, however, it is surrounded by loops of intestines, it is apt to undergo purulent and septic changes, and the ab- scesses may then become discolored and filled with stinking gases. The patient, whose previous improvement has been watched with delight, now loses appetite, the pulse becomes frequent, the strength fails, and death may follow from septic fever or from rupture of abscess into the abdominal cavity. In the pyaimic form — a still more deadly variety of peritonitis — the symptoms differ materially from those which have been recounted. As, however, it constitutes only a single one of the pathological PUERPERAL FEVER. 679 changes connected witli the poisoning of the blood througli the lym- phatic system, its consideration belongs properly to the stndy of the sep- tic infection. The Symptoms of Septicaemia Lymphatica (Septic).— The symptoms of blood-poisoning in the infectious diseases of childbed vary to a con- siderable extent according to the channel through which the septic •germs enter the general circulation. In the murderous epidemics which prevail in lying-in hospitals the lymphatics are, as a rule, the vessels primarily invaded. It is to this form that the cases already described belong, where, with diphtheritic patches upon the utero-vaginal canal and sero-purulent oedema of the parametrium, there are associated pye- mic peritonitis and deformation of the blood-corpscules ; or where, fol- lowing the migrations of the round bacteria, the serous cavities become successively involved, septic vegetations gather upon the heart, and the glomeruli of the kidneys become choked with micrococci. The lym- phatic form of septicsemia develops soon after labor, and is always ushered in by a chill. The temperature rises to 104° or even higher, and the pulse is thin and frequent. The abdomen swells rapidly, without being especially painful. Indeed, painless distention of the intestines is one of the characteristics of an acute invasion of the lymphatics. Peritoneal effusion is absent in cases which run a rapid course, and is distinctly recognizable only in a peritonitis of long continuance. The effusion is not so much due to exudation as to a transudation of serum with which micrococci are commingled. At the same time the tongue is moist, but slightly coated, and at times quite clean. Sometimes there is diarrhoea, due to catarrh or to a diphtheritic affection of the colon. When the bowels have been constipated, the administration of a pur- gative may provoke discharges which it may be found difficult to arrest. The skin is bathed in perspiration. At the beginning and during the course of the disease, bleeding at the nose is not of infrequent occur- rence. Toward the end, tlie pulse runs up to 140 to 160 beats, while in many cases the temperature falls. Immediately after death the heat of the body may for a short time exceed the highest point reached dur- ing life. The respirations are superficial and jerky. In many instances the face, the neck, and the fingers are blue from defective oxygenation of the blood. At the same time, the skin becomes clammy and the ex- tremities cold. The sensorium, in cases which run a rapid course, is usually affect- ed at an early period. The patients appear somnolent, are restless in bed, have light delirium, and respond only when spoken to loudly. As a rule, they make but little complaint, and, were it not for the dyps- noea, would have nothing to disturb their sense of comfort. Very few, even as death approaches, have any idea of the danger that threatens them. Now and then, in place of stupor, great restlessness, ggQ DISEASES OF CHILDBED. and even a maniacal condition, is developed. Albumen is usually found in the urine. Pleurisy, so frequently associated with lymphatic septicaemia, is fre- quently double, more rarely single, and begins, as a rule, with sharp pain in the side and an aggravation of the previous dyspnoea. Pericar- ditis is less frequent, and occurs usually, without symptoms, toward the close of life. The joint affections are characterized by redness and swellino-, and by pain, Avhich is sometimes so great that touching the inflamed part suffices to arouse the patient from sopor. Sometimes fluctuation is felt, but death occurs before perforation and discharge of the pus. The most frequent ending is death, which follows in from two to twenty-one days, and, as a rule, between four and seven days, liecovery is, however, possible. The Symptoms of Septicaemia Venosa (Phlebitis uterina, Pyaemia metastatica).— The putrid infection of a thrombus at the placental site may take place within twenty-four to forty-eight hours after labor. Usually, however, the approach is insidious, and the disease develops from an apparently insignificant endometritis or parametritis ; or the patient, with the exception, perhaps, of a tired feeling, of slight chilly sensations, and of profuse perspiration, may not have been conscious of any indisposition for days preceding the attack, or even until the first getting up from childbed. The initial chill, in typical cases, is charac- terized by its violence and duration. In some cases it may last for hours. It is accompanied and followed by high temperature, the fe- brile attack ending with profuse perspiration as in intermittent fever, with which it is apt to be confounded. The fall in temperature often assumes the form of a prolonged remission. In many cases, the pulse rises and falls with the variations in the body heat, while, in others, it remains permanently above the average. A frequent pulse is always a suspicious symptom in childbed, even where the other symjitoms are apparently normal. Erratic chills announce the lodgment of emboli in distant organs. With the formation of metastatic abscesses in the lungs and other parenchymatous organs, the t3']3ical character of the disease changes. In place of chills occurring at irregular intervals, followed by remis- sions and periods of apparent improvement, the fever is continuous, the pulse becomes small and rapid, while sopor, slight delirium, a dry skin, a dry, brown, cracked tongue, and a moderately tymjianitic abdomen, give the case the appearance of one of typhus fever. Peritonitis is present in hardly one third of the cases. The abdo- men is therefore flat and soft, and often is not sensitive upon pressure. Icterus, due to disintegration of the blood-corpuscles, is an ominous symptom. Death usually occurs in the second or third week. In the typhus- PUERPERAL FEVER. 681 like cases, however, it may follow the first attack speedily. Recovery is possible where the organs secondarily affected are not of too great im- portance. A combination of the lymphatic and venons forms of septicaemia is not uncommon in cases running a protracted course. The Symptoms of Pure Septica3mia.— Under the title of pure septi- caemia should be placed cases in which the absorption of morbific ma- terials into the blood gives rise to symptoms of intense blood-poisoning without the development of local lesions. A common exaniiDle of this form is met with in the fever which results from the presence in the uterus of decomposing coagula or portions of retained ovum, the fever subsiding with the removal of the disturbing cause. The symptoms are often similar to those produced by the injection of putrid materials containing rod-like bacteria into the vessels of animals. As the long bacteria do not possess the capacity of self -reproduction in the blood, to produce fatal results the quantity of putrid fluid injected must be large or be frequently repeated. This form is said not to be inoculable. In like manner we sometimes meet with cases of intense septic poisoning followed by speedy death, in which the post-mortem examination re- veals only changes in the blood and softening of the parenchymatous organs.

Causes of Puekperal Fever. The Atmosphere.— Micrococci multiply in hospitals when organic materials favorable to their growth are present in sufficient quantities. Perrin, Quenquand, and others have shown that the hospital wards in Paris, especially those upon the surgical and maternity divisions, con- tain an infinite number of vibrios, bacteria, and all the coccus forms (Charpentier). Robin has demonstrated the existence of albuminoid matters in water condensed upon vessels containing freezing mixtures and placed in overcrowded wards of hospitals. When the results of crowding become manifest, these albuminoid matters not only impart a fetid odor and putrefy with great rapidity, but rapidly impart putre- faction to healthy muscle and normal blood with which they are gg2 DISEASES OF CHILDBED. brought into contact. Pasteur was able, by the microscopic examina- tion of the lochia from patients in the services of Ilervieux and Lucas- Champonniere, to predict, from the character of the contained organ- isms, an impending attack of fever in advance of the slightest symptom betokening danger. The quality of the agents which pervade the air where hospital patients are confined is an important element in the genesis of febrile outbreaks. The bacterium termo, which causes putrefaction, is not in itself, as we have already mentioned, a source of danger. A stinking odor is not necessarily incompatible with a low mortality rate. The importance of the common forms of bacteria, according to Pasteur, re- sults from the fact that by their power to consume oxygen they pave the way for the active development of the pernicious germs, nearly all of which thrive only in media in wliicli that element has been materi- ally diminished. Again, there is reason to believe that the same germs are not always equally active for evil. The resistance of micrococci to carbolic and salicylic acids is found, experimentally, to depend in a measure upon the nature of the vehicle in whicli they are cultivated (Buchholz). The action of septic fluids varies, too, with the age of the infusions, with the materials employed, and with the conditions under which the poison-germs are generated. It was unquestionably the lochial discharge whicli, before the days of antisepsis, made it such a difficult task to keep a maternity ward in a healthful condition. Putrid blood has been found to be the most favorable material for septic experiments. In the summer months, so long as the windows were open and the air was diluted by the continu- ous passage of fresh currents, the patients usually enjoyed immunity from puerperal fevers. In the autumn, so soon as it Ijccame necessary to close the windows partially, on account of the cool nights, it was not uncommon for the more trivial disturbances, such as so-called milk fever, the hospital pulse, and catarrhal affections of the genitalia, to manifest themselves. Through the months of February, March, and April the mortality was usually greatest. During the winter months there was, as a rule, crowding of patients, insufficient ventilation, stag- nation of the air, and the rapid accumulation of disease-germs. That the later winter months should prove the most perilous is in accord- ance not only with the theory of continuous accumulation, but with the experimental fact that weeks sometimes elapse before a decompos- ing substance acquires the highest degree of virulence. Apart from the nosocomial malaria of hospitals, there is reason to believe in the influence, at times, of certain general widespread atmos- pheric states which affect the entire community. In the year 1871 the mortality from childbed in Xew York was 399 ; in 1872, 503 ; in 1873, 431 ; in 1874, 439 ; and in 1875, 420. Now, the excess in the deaths for 1872 was due wholly to an increase in the cases of mctria, PUERPERAL FEVER. 683 those from ordinary accidents remaining nearly the same as in the preceding years. The disease certainly did not extend into the city from the hospitals serving as foci, for the mortality at Bellevue Hos- pital was hardly more than half the usual average. There was no especial mortality that year from either diphtheria, erysipelas, or scar- latina, but the aggregate mortality was the largest known in the his- tory of the city. There are no positive data connecting the civil deaths from puerperal fever in 1872 with parasiticism, but the prevalence of epizootics, of epidemic catarrhal affections, of peculiarly fatal forms of pneumonia and other diseases which are now attributed to the presence of minute organisms in the atmosphere, renders such a soi;rce highly jirobable. It is proper to say here that, though the argument is very strong in favor of regarding the genitalia of puerperal women as the exclusive point of entry of infectious materials into the system, it seems impos- sible at the present time to make all the facts coincide with such a theory. I have the records of a number of cases occurring during an epidemic of puerperal fever in which patients were either attacked with fever previous to parturition, or in whose cases the unusual length of labor, the frequency of post-jjartum hemorrhage, and the imperfect contraction of the uterus immediately after confinement, were signs of some abnormal influence exercised upon the economy at an early period of labor previous to the existence of traumatism. That deleterious ma- terials may find other channels for entering the system than a wounded surface is evidenced by the cachectic condition not unfrequently pro- duced in physicians by too assiduous attendance in dissecting-rooms and places in which post-mortem examinations are conducted. One severe and rapidly fatal case of puerperal fever which occurred in Belle- vue Hospital I find it impossible to attribute to any other cause than that the woman, for five months previous to her confinement, served as a helper in a lying-in ward. The post-mortem examination dis- closed no special local lesions, but her symptoms were those of in- tense septicaemia. French writers report instances of toxemic condi- tions developing in young midwives during puerperal-fever epidemics. While we are not prepared to go as far as Tarnier, who says, " It is probable that the hmgs, by their extent and activity, offer conditions most favorable to absorption, and that often, if not always, it is by them that poisoning occurs," it does not yet seem time to give up the idea that, under exceptional circumstances, the respiratory and the digestive tracts may allow the passage of materials of a septic char- acter. Inoculation.— Unquestionably the most frequent source of puer- peral fever is by inoculation ; and yet, no longer than thirty years ago, the doctrine was combated as a pernicious heresy by both Meigs and Hodge, of Philadelphia, at that time regarded as the best authorities gg^ DISEASES OF CHILDBED. upon obstetrical questions in this country. Hodge, addressing his students, said : " The result of the whole discussion will, I trust, serve not only to exalt your views of the value and dignity of our profession, but to divest your minds of the overpowering dread that you can ever become, especially in women under the extremely interesting circum- stances of gestation and parturition, the ministers of evil— that you can ever convey, in any possible manner, a horrible virus, so destruct- ive in its effects and so mysterious in its operations as that attributed to puerperal fever " ; and Meigs, in his letters to students, writes : " I prefer to attribute them to accident or to Providence, of which I can form a conception, rather than to a contagion of which I can not form any clear idea, at least as to this particular malady." Con- trasted with these rhetorical utterances, in an essay published in 1843, by Prof. Oliver Wendell Holmes, entitled " Puerperal Fever as a Private Pestilence," the opposing testimony in favor of contagion was presented with equal literary and scientific skill. The evidence was complete and conclusive, and has exercised a most beneficial in- fluence upon the practice of midwifery in America. With his many claims to our admiration and esteem, there is probably no title which Professor Holmes wears with greater pride than th^t of pioneer in a movement that has done so much to prevent the slaughter of innocent women and the wrecking of happy homes. The ordinary carriers of infection are unquestionably the unclean hands, instruments, utensils, clothing, wash material, and the like which are brought in contact, during or after labor, with the genitals of the female. Barnes and other English writers lay considerable stress upon cases of puerperal fever due neither to contagion nor to atmospheric con- ditions, but to the poisoning of the patient by her own secretions. There is justification for this view in the fact that even normal lochia contain bacteria, and, when inoculated into animals, produce in them affections of an ichorrhfemic and septictemic nature. When death takes place, the tissues of animals thus treated are found to be filled with round bacteria. Furthermore, the disease artificially produced is in itself infectious, and can be continuously propagated in other ani- mals. But it may be asked, " Does not tliis admission cut both ways? How is it possible, if even normal lochia possess virulent qualities, that childbed is ever unattended by accessions of fever ? " To this we can only answer that the reasons for immunity in ordinary cases are only known in part. Karewski * and other experimental investigators have shown that the virulence of the lochia increases proportionately to the number of days that have transpired since the birth of the child, and * Experimentelle Untersuchun£:en iiber die Einwirkungen puerperaler Secrete auf den thierischen Organismus, Zeitschr. f. Geb. und Gvnaek., Bd. vii, 2ter Th., S. 331. PUERPERAL FEVER. 685 that, during the first three days, the locliia are comparatively harmless. Meantime, the retraction of the uterus, the closure of the sinuses, and the formation upon the wounded surfaces of protecting granulations, all act as natural barriers to the penetration of poison-germs. But, aside from these reasons, there is undoubtedly an unknown quantity calling for further investigation, which, in the absence of positive knowledge, we are content to term the predisposition of the individual patient. The vagina after childbirth possesses all the conditions most favorable for the production of putrefaction, viz., the access of air, fostering warmth, and stagnating fluids charged with dead tissue. It is probable that the first of these needful conditions is, in normal la- bors, happily wanting in the uterine cavity. In these days of intra- uterine medication it is well to bear in mind the relatively greater frequency of infection through vaginal and cervical wounds, as com- pared with that which takes place through the denuded intra-uterine surface. The term auto-infection may, with propriety, be employed as a distinctive appellation to designate those attacks of fever which, in the absence of any demonstrable cause, occur in the early days of childbed, and which there, quoad vitam, pursue a favorable course, and to cases of so-called late infection — i. e., where, after the fifth day, the accidental opening of a healing wound permits the tardy absorption of poisonous secretions ; but with the reserve that the primary cause is, in point of fact, atmospheric, and the predisposing condition the susceptibility of the individual. Cases of auto-infection are in this country extremely rare, if not unknown altogether, in salubrious or rural districts. Seasons. — On another occasion I have shown that in New York city the death-rate from puerperal fever is nearly twice as great during the six months from December to May, inclusive, as from June to November. The greatest mortality occurred in February and March, comprising . rather more than one fourth the entire amount. The smallest number of deaths occurred in September and October, in which months but one thirteenth of the entire number took place. Social State. — That puerperal fever, in its harvest of death, does not spare the wealthy and well-to-do classes is too familiar a truth to be worthy of discussion. That, however, the Avealthy do enjoy special immunities as compared with the less-favored members of society, I have shown by comparisons made between sections of the city which, though lying side by side, exhibit in a marked degree the two extremes of wealth and poverty. Thus, the mortality among the representatives of the lower social strata, in proportion to population, was from three to six times as great as that among the more fortunate classes. Relations to Zymotic Diseases. — In investigating, some years ago, the nature, causes, and prevention of puerperal fever,* I prepared, * Trans, of the International Med. Congress, Philadelphia, 1876. ggg DISEASES OF CHILDBED. from the statistics of the Health Board of New York city, tables ex- tendino- over a period of nine years to answer the inquiry as to whether tliere was any relation between the frequency of deaths from scarlatina, diphtheria, and erysipelas and those from metria. Previous to their publication, I was anticipated in my deductions by a paper upon the same subject by Matthews Duncan.* Neither Duncan nor myself found any such relation existing between the statistical frequency of puerperal fever and the zymotic diseases mentioned. There was, how- ever, nothing in our investigations to invalidate any direct testimony which tends to show that, in individual cases, a real connection between puerperal fever and the zymotic diseases may exist. Indeed, it seems to me to be fairly established that a poison may be conveyed from patients suffering from either of the foregoing morbid processes which may be absorbed by the puerperal woman, and may, in her, give rise to an infectious fever possessing an intense degree of virulence. Prevention, — Doleris formulates the indications for effective pro- jihylaxis as follows : 1, prevent the introduction of germs (antisepsis before confinement) ; 2, paralyze their action (antisepsis after confine- ment) ; 3, shut up the doors — veins, lympluitics, and Fallopian tubes (employment of means which promote uterine contraction). The results in the application of these rules are best shown in the modern statistics of lying-in hospitals. The records of the Health Board between the years 1868 to 1875, inclusive, showed that at that time nearly one sixth of the deaths from metria in New York city were contributed by the hospitals. To cite a single example : In the year 1873 there were 449 births in Bellevue Hospital ; there were 2") ma- ternal deaths, 15 of which were the result of septic infection. The proportion of one death from sepsis to thirty cases of childbirth was at that time the usual one in the maternities of tliis country and of Europe, reported differences being rather of bookkeeping than of fact. There was always, likewise, a large unreckoned contingent of patients with pelvic inflammatory troubles which ended in recovery. In 1874, between the 1st of January and the 11th of June, of lOG patients confined, 31 died of puerperal fever. Similar fatal epidem- ics were, at that time, of not infrequent occurrence in the best ap- pointed maternities. During the years 1885 to 1889, inclusive, 837 Avomen have been confined in the Emergency Hospital, and there have been 10 deaths, i. e., nearly 1 to 82. A glance at the record shows that these cases are the best illustrations of the difficulties with which the institu- tion has to contend, and of the value of the antiseptic principle. * On the Alleged Occasional Epidemic Prevalence of Puerperal Pyaemia, or Puerperal Fever and Erysipelas. Edinburgh Mod. Journal, March, 1876, p. 774. Recent observations have shown that morphologically the streptococci of erysipelas and those of puerperal fever are indistinguishable. PUERPERAL FEVER. ggT Thus, there were five deaths from eclampsia. The patients were all sent to the hospital after the convulsions had gained full headway. One was a case of placenta previa. The labor had been lengthy and the htemorrhages profuse before the patient was admitted. One was a case of Cesarean section, performed on account of the obliteration of the cervix and vagina by cancer. A patient was sent to the Emergency in labor, with delirium tre- mens. She died twenty-four hours after delivery. There were two deaths following version in neglected shoulder presentations. Both women had been in labor several days previous to admission. The children were dead, and decomposition had set in. In two cases the women had been respectively two and one half and four days in labor when admitted. The children were dead. There was a stinking discharge and commencing decomposition of the foetus. In tAvo cases the high-forceps operation had been performed surrep- titiously by unqualified persons. In both instances, the lower uterine segment was ruptured, and death speedily followed. In a twin pregnancy, where one child was delivered by forceps and the second by version after a long labor, death occurred from sep- ticaemia. There remains one other case, concerning which no record has been preserved. Thus, of the sixteen deaths, one, or possibly two, can be construed as due to puerperal fever. I have ventured to offer these particulars because there is no pre- tense that the Emergency is a model for imitation. It has no fans for ventilation ; no provision for a rotation of wards. It is intended for the homeless class. It receives constantly women with high temper- atures due to infection before their entrance, or who have been days in labor, or who have been subjected to unavailing attempts at artificial delivery by outside physicians. It therefore furnishes an excellent test of the value of modern antiseptic methods. Now, the regulations by which these results have been obtained are comparatively simple. The patient, on her entrance into the hospital, receives a full bath. A rectal injection is given. The lower abdomen, the inner surfaces of the thighs, the pudenda, and the anus are scrubbed with soap and water, then washed with plain water, and finally cleansed with a 1 : 1,000 solution of corrosive sublimate. The vagina is first douched with soap and water, and then with a 1 : 5,000 solution of corrosive sublimate. In operative cases these douches are repeated before and after the introduction of the hand or instru- ments. The Bellevue Hospital internes, while on duty, are not per- mitted to visit the dead-house or the erysipelas pavilion. They are not allowed to assist at surgical operations, nor to take part in the dressing of wounds. When in attendance upon a case of labor, both interne and ggg DISEASES OF CHILDBED. nurse wash their hands and forearms with soap and water, with pure water, and with corrosive-sublimate sokitiou (1 : 1,000), Before an internal examination is made, the hands are freshly washed with the bichloride solution. Infrequent examinations are recommended. In- struments are placed in a 2-per-cent solution of carbolic acid. After they have been used, they are boiled and polished for future service. The Crede method of expelling the placenta is employed. Ergot is given to secure good uterine contractions. In all cases after labor the vagina is douched with the bichloride solution (1 : 5,000). In cases of protracted labor, of high-forceps operation, of version, or of any manipulations by means of which air is admitted to the uterine cavity, the douche, after preliminary vaginal irrigation, is extended to the uterine cavity. The external parts are then dusted with iodoform, and are covered with a piece of gauze freshly wet with bichloride solu- tion (1 : 5,000). Outside is placed a pad of oakum. The dressing is changed once in six hours, at which time the genitals are scrupulously cleansed. During childbed no vaginal douches are given. In the main, the plan of treatment carried out is tluit introduced by Garrigues at Charity Hospital five years ago. Its success is attested not only by the absence of deaths due to septic infection, but by the morbidity in the wards. The temperatures rarely rise above 100^°, and, as a rule, do not reach 100°. But the plan of treatment presup- poses intelligent instruments. For us these are supplied, on the one hand, by the training-school for nurses ; on the other, by the hospital interne, who enters upon his duties thoroughly familiar with the re- quirements of surgical cleanliness. The occasional appearance on the scene of an individual who uses his " common sense " — i. e., one who does not believe there is any harm in witnessing an autopsy, or in visit- ing a companion in the erysipelas ward, or in holding the pus basin in an operation for pyo-thorax — is almost certainly followed by tempera- ture elevations, which add fresh testimony to the efficacy of a rigid observance of antiseptic regulations. It is, however, to be acknowledged that there is by no means una- nimity among authorities in relation to certain of the rules prescribed. Thus, the pad to the vulva is sneered at, by many, as savoring of the heresy that the air can become the source of contagion. For my own part, I believe an antiseptic dressing and pad are of immense service in hospital practice, where patients are aggregated together, as a means of preventing the decomposition of the lochia. The latter is inevitable upon the external parts when the ordinary napkin is employed. It seems to me incontrovertible that the air does thereby become contami- nated, and it is doing violence to the evidence to deny the pernicious influence of a germ-laden atmosphere upon puerperal wounds. The argument that such an admission has a tendency to weaken the per- sonal responsibility of the physician is childish. Aside from the fact PUERPERAL FEVER. 0g9 that science is based upon truth, and not upon teleological considera- tions, the belief in a twofold origin of puerperal fever simply doubles his responsibility. To be sure, Leopold* found that of 427 patients in the Dresden Maternity, who had not been examined or treated with corrosive sublimate previous to confinement, only 7 had a rise of tem- perature, and this fact taken by itself would seem to indicate that direct contact alone is capable of producing infection. But these patients were confined under favorable sanitary conditions. Szabo,f on the contrary, during an epidemic of fever in the Pesth Maternity, gave orders that no examinations should be made. Of 90 patients con- fined under these conditions, more than one third had febrile disturb- ances ; and two of the patients, upon whom, in one case, sutures and, in the other, serres-fines were employed for perineal laceration, died. The researches of Ott J and Thomen * show that in healthy women the bacteria contained in the lochia are found, not in the upper por- tion of the vagina, but near the introitus, which would certainly indi- cate that they are ordinarily derived from external sources. At any rate, since the use of the pad at the Emergency Hospital, it has been possible to do away with the old-time rotation of wards, and the febrile temperatures, which once were so marked a feature of the winter months, when the windows were closed, are now no longer observable. The subject of prophylactic douches, during labor, has likewise been one of endless contentions. In private practice they are certainly needless. Their employment at the Emergency has not, however, been the result of theory, but has been the outcome of the condition of the patients admitted, most of them having been examined previously by not overfastidious midwives or physicians. The differences which divide obstetrical authorities concerning the ante-partum douche is not so much the result of conflicting experiences as of doctrinal convictions. Thus, Barnes, Ahlfeld, Kaltenbach, and others, have shown that, in spite of every pains taken to exclude con- tact-infection, temperature elevations will occasionally occur in child- bed. These febrile disturbances they regard as the product of a materies morli^ existent in the genital canal prior to labor ; or, to use a term which at present is not only a designation, but a war-cry, such cases are due to auto-infection. It is a matter of common agreement that, in severe cases of puerperal infection, the utero-vaginal canal swarms with bacterial forms, and that, of these, the streptococcus pyo- genes is the most certain accompaniment of specific inflammatory * Leopold, Dritter Beitrag zur Verhiitung der Kindbiltfiebers, Arehiv f.

When convalescence sets in, the coccus forms correspond- ino-ly disappear from the lochial discharges. But the vagina at all times contains a varied assortment of bacterial germs. Nothing would seem simpler, therefore, than the deduction that these germs are al- ways potential sources of evil. As a logical outcome of this doctrine, its extreme supporters insist upon a complete sterilization of the vagina in every case of labor as an ordinary prophylactic precaution. Thus, Steffeck * advises the irrigation of the vagina during labor, at two-hour intervals, with a litre of corrosive-sublimate solution. To increase its efficiency he introduces two fingers into the vagina to scrub, during the douche, first the vaginal mucous membrane and then the interior of the cervix. Doderlein f recommends that the vagina be first rubbed thoroughly with a preparation of creolin and molliu, and then be irri- gated, for ten minutes, with a creolin solution. Fortunately, these suggestions, which would have a tendency to handicap fatally the employment of antiseptic measures in midwifery, have not been received with much favor, even by the partisans of the doctrine of auto-infection. But, on the other hand, the pathogenic character of the germs contained in the vagina has been disputed. Thus, Artemieff I says that " the lochia of perfectly healthy puerperal women contains no micro-organisms." Bokelmann ** maintains that a healthy, normal puerperal woman is a priori to be regarded as aseptic. He objects to attempted sterilization on the ground that the measures emjDloyed mechanically delay the progress of labor by the removal of the normal vaginal mucus, and at the same time render more vulner- able the tears, the excoriations, and the surfaces from which the epi- thelium has been detached. Kaltenbach,|| althougli a defender of auto-infection, states that in easy, rapid, births the germs are carried away by blood, amniotic fluid, and the passage of the child ; but in tardy labors, or in case of the premature rupture of the membranes, the entrance of germs into the uterine cavity is facilitated, and many may remain in the uterus and become a source of danger. Diseases resulting from auto-infection are lighter in character than those due to inoculation. Infection is first preceded by putrefaction. A complete destruction of germs is unne- cessary ; those that remain in ittero are rendered harmless by ordinary injections. Even Winter states that, in the present condition of our * Steffeck, Ueber Disinfection des weiblichen Genital-canals, Zcitschrift flir Geburtskunde, vol. xv, p. 395. f Doderlein und GCnther, Disinfection des Geburts-canals, Archiv fur Gynakologie, vol. xxxiv, p. 111.

PUERPERAL FEVER. qqi bacteriological investigations, it is not right to carry out the attempts at complete sterilization recommended by Steffeck and Doderlein. In private practice, under ordinary conditions, the presence in the vagina of infectious forms of bacteria is hardly conceivable, except in cases where they have been directly imported by the finger or by in- struments. This statement is based both upon microscopic investiga- tions and upon clinical experience. So far, it has not been possible, m the rare instances where beaded cocci have been found in the vaginal secretions, ante-partum, to obtain by pure cultures a product capable of giving rise to spreading inflammations ; and in rural districts, even with not overcleanly surroundings, immunity from infectious puer- peral diseases is the rule. That, however, the vagina, which is not a hermetically closed tube, should, like the atmosphere, contain germs capable of producing putrefaction is hardly doubtful. Under healtliy conditions the uterine cavity, on the contrary, contains no bacterial forms, and it is not invaded by them in normal parturition, a fact at- tributed to their feeble migratory power and to the downward current of the secretions.

With 7 full page Colored Plates and 203 Illustrations. Cloth, $6.00 , sheep, $7.00 ; half morocco, $7.50. soi.r> o:NrLY by sxjbscripxion'. Azaerican Medico-Surgical Bulletin: " This work is in every sense of the word a new book ; for, while the best work of other authors in this and other countries has been di'awn upon, especially that in tlie form of monoi^raphs and in the flies of paediatric literature, the majority is derived trom the author's own clinical observations. Obsolete dicta handed down from te.xt -book to te.\t-book are here conspicuously absent, and nothing has been accepted which has not been carefully tested. ... It is not veuturinar too much, after a careful perusal of these pages, to predict for tliis volume a pre-eminent and lasting position among the treatises upon this subject. We heartily recommend that it iiud a place not only in the library of every physician, but wide open at the elbow of every man who desires to deal intelligently with the problems which confront liim in the treatment of infants and children intrusted to his care." ITashviUe Journal of Medicine : " This mainiflecnt work is one of the most valuable recent contributions to medical liter- ature. It will rapidly win its way to a front rank with other standard works upon kindred subjects. It is as nearly complete as a treatise upon tliis subject can be." Virginia Medical Semi-Monthly : " When one recalls the teachings of a decade or two ago and compares the inculcations of to-day, he can scarcely help recognizing that ' old thing's have passed away, and all things have become new.' The volume befoi-e us is practically the record of information obtained by the author from eleven years of special study and practice, so that nearly every subject is presented from the standpoint of personal observation and experience. The information given is therefore reliable, for Y)r. Holt is a close observer and a careful student of his ripe experience. ... In short, this book appears to us to be the best all-round, up-to- date book for practitioners and students of children's diseases that we know of." Medical Progress : " The work before us is one which reflects great credit upon the distinguished author. r>r. Ilolt has long been known as a most industrious and painstaking investigator, and in this volume he sustains that reputation. The work, we may say in a sentence, is fully up to the requirements of the times, and there is no advance known to piediatrics which has not been fully dealt with according to its merits." D. APPLETON AND COMPANY, NEW YORK. TPIE MENOPAUSE. A CONSIDERATION OP THE PHENOMENA WHICH OCCUR TO WOMEN AT THE CLOSE OF THE CHILDBEARING PERIOD, WITH INCIDENTAL ALLUSIONS TO THEIR RELATIONSHIP TO MENSTRUATION. ^Iso a Particular Consideration of the Premature {especially the Artificial) Menopause. By ANDREW F. CURRIER, A. B., M. D., NEW YOKK CITY. 12mo, 28Jf pages. Cloth, $2.00. " Such a universally important topic as the menopause deserves the extended consideration given it in this volume. The author takes the ground that this period of woman's life is not so fraught with danger as taught in previous works on the subject. He also corrects the prevalent idea of an intimate relationship be- tween cancer and the menopause. Artificial menopause is carefully considered. It is a most valuable book, and should be in the hands of every physician." — Nash- ville Journal of Medicine and Surgery. " This is a remarkably interesting treatise upon a subject but scantily dealt with by writers upon general medicine. The author has taken great pains to make a thorough study of the topic, and his conclusions are arrived at by logical methods of reasoning. He shows, what many medical men have long suspected, that the climacteric is not of itself a cause of disease, and that normally it passes by with- out observable effect." — Northwestern Lancet. " This is a sensible, honest book. Through it the author has made a contribu- tion to medical literature of more than ordinary value. This conclusion is reached not because of the great intrinsic value of the facts adduced, but because ^very page bears the earnuii'ks of conscientious research. If Dr. Currier has not given us more scientific knowledge than we possessed before, it is, we are convinced, be- cause such knowledge is unavailable." — Medical News. " The monograph before us is certainly one which has been long demanded by the medical profession. . . . Taken altogether this is a most excellent little book, which we can heartily recommend to all physicians as the latest and most advanced and consequently the best on the subject." — St. Louis Medical and Surgical Journal.
