II. Meeting, November 29th, 1878. W. IT. Byford, m. d., in the chair. Dr. Edward Warren Sawyer read the following report of a fatal case of Inversio Partialis Uteri Puerperalis. . Mrs. B , 38 Aldine square, aet. 35 years, of small, frail physique ; multipara, last labor five years ago. She fell in labor at midnight, Dec. 19, 1877 ; an hour afterward, I saw her for the first time. I was struck by the unusual size of the abdomen, which suggested multiple pregnancy. The lower extremities were very oedematous, and had been in this condition for several months. Upon examination, I found the os two-thirds opened, the vertex in advance, and still very high. Her pains, which returned with natural regularity and frequency, were short and sharp, lacking in force ; they were not well borne by the patient, who frequently demanded ether. At 2 a. m. the os was fully opened. Upon rupturing the membranes, there escaped the greatest quantity of liquor amnii I have ever encountered, the water inundating the bed and fall- ing upon the floor. Her abdomen soon assumed the size usual to this moment. The head was well engaged in the excavation, in the third position of the vertex (R. 0. P.), the anterior fontanelle occupying the centre of the field. In auscultating the tumor, I heard but one foetal heart, on the median line just below the umbilicus ; pulsations 144 in the minute. After wait- ing for several contractions of the uterus, which appreciably VI CHICAGO GYNECOLOGICAL SOCIETY. advanced the head, I began to allow the patient to inhale ether during the accession of each pain. During the intervals, she was quite conscious, and kept up an intelligible conversation with her husband and her attendant. The effect of this obstet- rical degree of anaesthesia was most happy ; the woman bore her pains without complaint, and they were noticeably increased in force, though still shorter and weaker than natural. At 4:30 a. m. the occiput had rotated forward, into the second position, and the head was well engaged in the outlet of the canal. I now carried the anaesthesia to the surgical degree for a moment, applied my short forceps, and delivered the head within ten minutes. All ether was discontinued from this moment. There was a pause of at least five minutes, when I became soli- citous for the infant, who did not close the gums upon my finger in the mouth, and so completed the extraction by hooking my finger into the leit axilla. During this time, the husband, under my direction, was compressing the uterus with both hands ; this compression he continued until relieved by me. The child required a vigorous slapping and cold douche before it would breathe. After the lapse of about ten minutes—the woman in the meantime seemed in a natural sleep—I passed my finger into the vagina, and found the placenta partly extruded through the mouth of the uterus ; I completed its delivery with less difficulty than usually obtains. The patient wakened at this moment, and simply said, “ Don’t.” I examined the abdomen, and felt the uterus very flaccid and reaching to the umbilicus, hut uniformly rounded. A few minutes later, not more than fifteen — the husband in the meantime keeping up compression—I noticed a pallor of the woman’s face, who opened her eyes and yawned. I quickly raised the bed-covering, and saw that a rather brisk haemorrhage was going on ; the pulse was rapid and very feeble. I put my hand upon the belly, but covld not plainly feel the outlines of the uterus. I sunk my hand deep downward, and had but little difficulty in compressing the aorta against the vertebral column, though the woman complained that my pressure was uncomfort- able ; this procedure completely arrested the haemorrhage. As INVERSIO PARTIALIS UTERI PUERPERALIS. soon as the nurse could pour a teaspoonful of Squibb’s fluid extract of ergot from a bottle, it was given to her. I called for ice, which was not in the house. While the husband went for ice, I slapped the abdomen with a cold wet towel. The dose of ergot was repeated twice in the next half hour. Ice was soon procured, and I hastened to rub the hypogastrium with a lump ; I also passed a lemon-shaped piece into the vagina as far as the mouth of the uterus, which presented nothing unusual. The uterus immediately contracted, and its outlines were easily made out through the abdominal parietes; the upper border was not now rounded upward, as the fundus usually is, but was represented by a straight, hardened edge, extending transversely across the hypogastrium, at a point nearly midway between the symphysis pubis and umbilicus. This edge was quite like the rim of a bowl. At either side, and resting upon this rim, a spherical body, continuous with a rounded cord, could be easily felt (the ovary and tube). It now flashed upon me that the fundus of the uterus had fallen downward into the cavity of the organ. This discovery was made about forty minutes after the delivery of the placenta, and some twenty-five minutes after I had once felt the fundus flaccid, but rounded upward. I ceased my compression of the aorta, and no more blood wTas lost. From this moment, the uterus was in a state of tonic spasm, as if completely ergotized. At no time could I detect the slightest relaxation, though I long- ingly watched for this event. I passed my hand into the vagina, and found the uterus unusually high ; the os was opened to the extent of about four centimeters, and rigid. A segment of the prolapsed fundus could be felt looking through, and in contact with the open mouth. The contrast in the feel of this circular area of spongy fundus, with the smooth covering of the vaginal portion of the cervix, made it of easy recognition. I shaped my hand into a cone, which I impinged against the fundus, through the os, at the same time making a 'point d'appui with my left hand upon the upper rim of the uterus, through the abdominal walls. In this manner I was enabled to exercise a degree of force in attempting to push the fundus upward, such CHICAGO GYNAECOLOGICAL SOCIETY. as I feared would tear the uterine tissue ; but I made no impres- sion upon it; the organ felt like cartilage. The patient fainted during this effort at replacement; the pulse disappeared from the wrist, and I rvas obliged to desist. A dose of morphia, with brandy, was given by the mouth, and brandy was also thrown into the rectum. The trunk was surrounded with bottles of hot water, and frictions faithfully used ; the foot of the bed wras also raised. In a half hour, these measures were rewarded by a marked improvement; the color had returned to her face, and the pulse was quite strong at the wrist. I now made a seeond attempt at replacement, but with the same futile result; the poor woman complained of pain, and again fainted. The respiration soon became sighing ; there was great jactitation, and our united efforts were required to keep her upon the bed. She wras deliri- ous, jumped from one side of the bed to the other, crying, “ I shall be uncovered,” and no efforts of ours could prevent her kicking herself naked. The ensemble constituted a scene which can never be effaced from memory. All efforts at resuscitation were kept up faithfully, but without avail. The unfortunate lady soon became moribund, and died very quietly at eight o’clock, about three hours after delivery, rather more than twTo hours after the inversion was recognized, and about one hour after the second effort at replacement of the fundus. Dr. Byford reached the house some ten minutes before dissolu- tion, and recognized the utter hopelessness of the case. The abdomen was examined fifty-five hours after death, and the uterus, which was preserved, was found in the state already described. Its tissue was not torn. There was no difficulty in replacing the fallen fundus at this time. The child was a male, and weighed ten pounds. Remarks. This accident, which is one of the gravest that can befall a puerperal woman is, fortunately, one of extreme rarity; since it occurred but “ once in upwards of 190,800 deliveries at the Rotunda Hospital. ” * * Playfair, Treatise of Midwifery, Philadel., 1876. INVERSIO PARTIALIS UTERI PUERPERALIS. The result in this case was not exceptional.* Of seven cases seen by Hamilton, “ in one single instance only the woman sur- vived the shocking accident.” f It is a common observation, that the loss of blood and shock are greater in the incompletely inverted uterus, when the fundus is grasped by the body, than when the organ is turned quite inside out. J The most common variety is the incomplete; § hence the great mortality attending the accident. The reflections suggested by the case in point are: first, as to the cause of the accident. The undue distension of the uterus by the liquor amnii undoubtedly weakened the uterine walls, so that, when the organ was emptied, the fundus could easily fall into the cavity of the body. This enfeeblement was recognized before delivery, through the short, sharp, weak pains. The almost universal observation made by the older authors, that inversion of the uterus is generally caused by the attendant dragging upon the cord of the undetached placenta, has abso- lutely no application here; for the placenta was entirely detached spontaneously. Second, as to the management of the accident. Writers agree upon the importance of immediate replacement of the inverted organ. Surely it is to the reposition of the organ that we are to look for a relief from dangerous shock, and security against haemorrhage. As a rule, according to authors, the imme- diate replacement of the fundus is not difficult. But an insur- mountable obstacle in the way of such success in this case was the condition of tonic spasm, which at first seemed due to the adminis- tration of ergot. One cannot refrain from expressing a regret at this point, though it is true that the effects of ergot -were indi- cated by the post-partum atony of the uterus. There is consola- tion in the fact, moreover, that some portion of the uterus is usually spasmodically contracted, when there is atony of the organ, when no ergot has been given. || This patient succumbed to the shock incident to having the * Velpeau, Traite de l’art des Accouhemens, Paris, 1835, f Hamilton, Outlines of Midwifery 1784.

The shock may have been augmented, under the circum- stances, by the loss of blood ; but I have more than once seen a greater hgemorrhage with no appreciable effects upon the woman. Discussion. Dr. Miller : The subject introduced this evening by Dr. Sawyer, is one of more than ordinary interest to every accoucheur. The report of the case is admirable, and the specimen presented adds greatly to its value. I have no criticism to offer in regard to the management of the case, for it was faultless. The acci- dent happens but seldom. It was fortunate that in this case it occurred under the immediate observation of one so competent to comprehend its gravity from the initial stage, and who could pre- sent to us so clearly its complete history. The causes of inversion of the uterus are various — generally, I believe, mechanical; not always so, however. I can appreciate that inversion may take place as follows : The uterus in a state of complete inertia, from long continued labor, from too sudden delivery of the child, or from over-distension, as in Dr. Sawyer’s case, a slight cause may produce depression and end in inversion. That cause may be the increased weight of that portion of the uterus upon which the placenta was developed, if near the fundus, together with the other condition which obtains at the site of placental development, namely, the projection inward of that part of the uterus. The structure of the uterus, immediately surrounding the placental site, in the condition assumed, could offer no resistance to the further settling internally by gravity of this heavy circumscribed portion of the uterus — depression hav- ing occurred, inversion would follow. Another possible cause of inversion mayjibe mentioned, though not strictly applicable to the case reported this evening. When the uterus is in a state of complete inertia, and the placenta has been detached, and has lodged within the os uteri, the cavity of the uterus, as is usual in such cases, remains large, and is filled with blood. The extraction of the placenta will act as a piston upon the volume of blood in the cavity of the uterus, and this, in turn, will act upon the flaccid wall of the uterus ; the fundus INVERSIO PARTIALIS UTERI PUERPERALIS. may follow this forcible extraction of blood, till depression is pro- duced. Then inversion may be completed by the uterus itself. I am not certain that attempts at compressing the uterus may not produce a dimpling of the organ that will lead to inversion, especially if performed carelessly, or by a person not familiar with the physiology of uterine contraction. It appears to me that inversion is liable to be caused by the injudicious application of force to the uterus in a state of inertia. Dr. Roler : The case presented for discussion is an interest- ing one, but the cause of the inversion cannot be determined, as the attending physician has no knowledge of the exact moment of its occurrence. The delivery of the placenta evidently had nothing to do with the accident, as manipulation immediately afterward detected the outline of the uterus in a flaccid state, the fundus being near the umbilicus. Ergot w7as administered, and firm pressure applied both over the uterus and upon the abdomi- nal aorta. A little later, wThen contraction suddenly occurred, the cup-shaped depression was easily recognized by the hand over the abdominal parietes. The fundal sinking must have taken place before contraction set in, as symmetrical action of all the muscular fibers would in- sure safety against such an accident. The condition of ergotism may have been the chief cause of failure in the attempted repo- sition of the uterus, but the administration of the drug was clearly indicated, and Dr. Sawyer did as any intelligent physician would have done under the circumstances. I fully endorse the remarks of Prof. Miller with reference to careful manipulation in the removal of the placenta, even after uterine action has thrust it into the vagina. Leisliman, J. Matthews, Duncan, and others, state that if left alone it usually presents edgewise during expulsion, hut I think the bedside experience of every physician proves that, without meddlesome interference, it is often found foetal surface foremost, and “impacted” in the vagina. Of late years I have always, when removing it, waited until I found the uterus well contracted above the pubis. It ought to be brought out edgewise and slowly. Traction upon the cord would cause a vacuum above, which would be filled with blood from the open sinuses, or if atony was CHICAGO GYNAECOLOGICAL SOCIETY. present, possibly by depression of some part of the uterine wall. In regard to the forces which operate to bring about complete inversion, I would like to state my doubts as to the ability of the organ, by any contractile power, to invert itself. I am aware that it has become an accepted doctrine that the introverted part may be seized by the remaining portion, and be carried downward, thus completing the process by its own action. I do not think it has been satisfactorily proven by any one who has written on the subject. In what way can any expulsive force be developed when the fundus is not acting ? It is a matter of common experience when the uterus fails to contract symmet- rically, in any stage of labor, that the expulsive process is arrested. In irregular contractions, even the detached placenta is held in vice-like grasp until artificially removed. If the introverted part contracts, it shortens itself merely. If the encircling portion acts, the further descent must certainly be arrested by the grasp of the circular fibers. Are not the incomplete varieties owing to this fact ? When general atony exists, the weight of the descend- ing portion, aided by the straining on the part of the patient, will easily carry the fundus into the vagina. Irregular contraction is doubtless a primary condition in many cases, of incomplete inversion, the placental area being the para- lyzed portion, and sinking downward either from spontaneous or artificial causes. Yet, even in these cases, it can easily be under- stood how the shock thus produced, together with haemorrhage, might subsequently cause general relaxation and allow further descent of the fundus. Dr. Merriman was very much interested in the case, which had been reported in so clear and minute a manner. These dangers, although rare, were liable to occur at any time, and there was need to observe as closely as possible all circumstances connected with them, that the causes of the trouble might be more perfectly understood. He did not remember having seen an explanation offered for the first step in the process of inversion, namely, that of depression, except; 1st, the presence of a polypus; 2d, drawing upon an adherent placenta; 3d, pressure from above; but these were evidently not the only causes. Dr. Barnes gives as a circumstance frequently connected with this INYERSIO PARTIALIS UTERI PUERPERALIS. difficulty, the attachment of the placenta to the fundus uteri. Since the placenta undergoes absolutely no detachment during the strong contractile efforts of the uterus during labor, it seems probable that the placental seat is less affected generally by uterine contraction. If, then, the attachment should be at the fundus uteri, and an unusually relaxed state of the uterus exist, a very little pressure would be sufficient to start a depression which, once started, would readily go on from the contractile efforts of the uterus itself. He thought of one other explanation. If irregular contrac- tions should occur, they might affect only the external fibers of the uterine fundus, and it would readily be seen that this circum- stance would cause the wall of the uterus to bulge inward, thus producing the initial step in the process of inversion. He thought, in this connection, that the effect of ergot, which is so liable to produce irregular contractions of the uterus, should be carefully watched. Dr. Nelson : It has not been my fortune yet to see a case of puerperal inversion of the uterus, but I can readily understand that the piston-like action of the placenta, referred to by Dr. Miller, might be, in a relaxed condition of the uterine walls, a cause of partial or complete inversion, if the cord were drawn upon while the uterus was thus relaxed. For this reason I make it a rule never to attempt to remove the placenta until the uterus is contracting firmly. Then, if gentle traction on the cord, or the presenting portion of the placenta, does not readily extract it, and especially if it seems to be firmly held, while the foetal sur- face presenting at the os shows that it is at least partly detached, I bore through the presenting placental mass with the forefinger, to allow the air to pass through the placenta, and thus destroy this sucker-like action, and then the contents of the uterus may be readily removed. But until this is done, or in some way the air allowed to get behind the placenta, traction upon it or the cord will simply drag downward the uterus and its contents until the uterine contractions excited thereby expel the contents. I do not recollect to have seen this procedure described in any of the books, but I have, for several years, found it to greatly facilitate the removal of the placenta. CHICAGO GYNAECOLOGICAL SOCIETY. Dr. Sawyer’s exact description of this case suggests also another possible cause of inversion, when the uterine walls are dis- tended and relaxed, namely, pressure upon the uterus through the abdomninal walls by an assistant, especially if unskilled. For I well remember, in assisting Dr. Roler in a footling case, under ether, while pressing firmly upon the fundus of the uterus to hasten the delivery of the head and so save the child, I dis- tinctly felt the walls of the uterus dimple under the pressure, especially when too great force was momentarily exerted by the thumbs and finger points in attempting to relieve the hand, and while the uterus was not firmly contracting. Indeed, the inertia of the uterine walls was the very reason for using these vigorous external means to hasten delivery Dr. Sawyer describes the compression of the aorta from the outside, which seems to have been satisfactory in his case ; but, if the abdominal walls contain much adipose tissue, it might be more difficult. Following the teachings of my preceptor, Dr. Storer, of Boston, I should prefer to pass the hand directly into the uterus, and compress the aorta through the thin uterine walls. I have not found it difficult to introduce the hand into the uterus immediately after delivery, and the aorta can certainly be as safely compressed in this way upon the spine. Furthermore, the hand itself, in the uterus, will be a powerful means of exciting the uterine contraction, and should any portion of the walls be inverting, it would be in the best possible position to detect and replace it. It is also in position to detach the placenta, if this may have been the cause of the haemorrhage, or to remove clots resulting from the haemorrhage. I have had occasion to compress the aorta in this way but once, and saw no bad results. As the tetanic contraction of the uterus wras described in Dr. Sawyer’s case following the use of ergot, the query came to mind* will the use of ether, carried to complete anaesthesia, in such cases, overcome the action of the ergot ? I would also like to ask the members of the society what their experience is in the use of the corn ergot—the fluid extract of ustilago maidis ; will it produce, in full doses, these same tetanic contractions which the rye ergot frequently does? I have used the fluid extract of ustilago in my obstetric practice during the INVERSIO PARTIALIS UTERI PUERPERALIS. past year and a half, using it as I would the rye ergot, in doses of half a teaspoonful and more, and I have not yet seen the severe contractions occasionally produced by the rye ergot; neither is it as liable to disturb the stomach as that—perhaps because the taste is usually not as disagreeable to the patient. Dr. Jones said that he had little to add to what had already been said as to the etiology of inverted uterus. During the discussion, it had occurred to him that possibly, as in early abortions, a certain balooning of the upper vaginal and lower uterine ligamentous structures might occur after parturition, which would draw apart the inert walls of the womb, and suffer the flaccid fundus and upper segment of the organ to fall into the cavity thus made. Then, under the stimulus of invagination, active contraction, grasping the inverted portion, might be set up, which would tend to complete the “ perversion,” or render it impossible for the attendant to effect its reinstate- ment. It was possible that the ergot administered in the case reported might have proved a disadvantage, but that it had any- thing to do with the causation of the accident, he could not believe. He agreed with other speakers in thinking inversion due mainly to uterine inertia, and that the uterus was not prima- rily active. As for the commonly assigned cause—traction upon the funis— he averred his constant practice of that forbidden means of delivering the placenta, but always with the premise of normal uterine contraction. A case of puerperal inversion of the uterus had never occurred in his own pi’actice. Dr. Fitch : I regret exceedingly that I did not arrive in time to hear the opening of this discussion, and the history of the case presented by Dr. Sawyer. My experience in puerperal inversion of the uterus has been very limited ; indeed, in an active practice of twenty-seven years a case has never occurred under my own administration. The only case I ever saw was in consultation. About twenty- two years ago, I was called to see a woman four or five days sub- sequent to her delivery. I found the patient of light complexion and frame, pale and haggard countenance, pulse 130 to 140, and feeble ; skin cold, and covered with a clammy perspiration. Her CHICAGO GYNAECOLOGICAL SOCIETY. labor was apparently normal. No excessive haemorrhage had occurred, and no great degree of pain ; yet there was constant vomiting, and great prostration. The physician in attendance had made no diagnosis, but supposed she had “child-bed fever.” I proceeded to make an examination per vaginam. The uterus was low in the pelvic cavity; os open to the size of a silver dollar, and a hard, somewhat roughened convex body pre- senting, which I at once suspected to be the fundus uteri. I immediately applied firm pressure with two fingers against this body, and counter pressure upon the abdomen, for the space of five minutes ; the body gradually receded from the os, and sud- denly left my fingers, with a decided thud ; at the same instant the uterine tumor appeared in the hypogastrium. The vomiting ceased at once ; reaction quickly came on, and the patient made a good recovery. In regard to the influence of ergot in the production of this accident, I believe that its action is upon the entire organ, pro- ducing uniform contraction of its muscular walls ; therefore can- not favor the accident. My judgment is based on the use of it in probably 75 per cent, of all the cases I have attended during the past twenty years. I believe it is useful in assisting the delivery of the placenta; and further, by producing tonic contrac- tion, it thoroughly empties the uterus, and prevents accumulation of blood in its cavities. For these purposes it is given from 10 to 20 minutes before the completion of the second stage of labor. I have entertained the opinion that acute puerperal inversion was unnecessary ; and that, when it did occur, it was usually due to neglect in the management of the delivery, or by too active interference. To avoid this accident, as well as post-partum haemorrhage, I am in the habit of pursuing the following course: As soon as the child’s head is delivered, I direct the nurse, or other con- venient person, to apply the hand to the hypogastrium, and follow the receding walls of the abdomen, with pressure directed upward and backward. The person is retained in that position till I have attended to the child, tied and severed the cord. I then place the patient on her back, and apply my free hand to the abdomen, over the uterus, grasping the organ with the thumb and INVERSIO PARTIALIS UTERI PUERPERALIS. twTo or three fingers, with the little finger resting on the fundus, for the purpose of promptly detecting any depression or dimpling. If the uterus does not contract promptly, I squeeze it forcibly. As soon as contraction occurs, I apply traction on the cord, equal to a weight of one half lb. to six lbs., at the same time pressing the lateral walls of the uterus, for two purposes: 1st, to assist in the expulsion of the placenta ; 2d, to sustain these walls in apposi- tion, and thus prevent inversion. Should dimpling be felt, I at once desist from traction; or should tearing be felt in the cord, traction should cease. 1 have never torn off a cord or inverted a uterus. Dr. Etheridge remarked that the specimen before the society seemed an unusually large puerperal uterus. Dr. Jackson had nothing to add to what had already been said in reference to inversion of the uterus. He had never been so unfortunate as to encounter a case in his own practice, and the specimen now before the society was the first he had ever seen. He only desired to express his surprise at the opposing views to which utterance had been given in reference to what should con- stitute the proper treatment of the third stage of labor, in its bearings upon the causation of the accident in question. One gentleman considered it dangerous to make pressure upon the fundus of the uterus in order to aid the expulsion of the placenta, while another thought this method the best and most favorable. Several regarded traction by the cord as highly dangerous, while others again, on the other hand, habitually delivered by pulling at the cord, and only limited the strength of the pull by the strength of the cord. A number were in the habit of administering a dose of ergot to aid the expulsion of the placenta, while another was afraid to give it lest it should not be expelled at all. Inversion of the womb was usually considered to be a very rare complication of labor ; and yet, after listening to this discussion, it seemed wonderful that it was not a very common one. He thought the efficiency of some of the alleged causes was exaggera- ted. Certainly traction of the cord was. If it ever caused in- version, it must be only in exceptional cases; for he believed that fully 90 per cent, of all placentae wrere delivered by more or 24 CHICAGO GYNAECOLOGICAL SOCIETY. less traction by the funis. His own impression was, that puer- peral inversion occurs usually from a passive, inert, relaxed con- dition of the uterine walls, produced by over-distension, as in the case described by Dr. or from some other causes. Dr. W. H. Byford believed that mere atony of the uterus was not a sufficient cause of inversion of the uterus. This con- dition might be a predisposing cause, and it was probably in this state of the womb that pulling on the cord and other injudicious efforts to deliver the placenta were rightly blamed as causes of inversion. He thought, however, that inversion more frequently resulted from irregular contraction of the uterus, in the sense that some of its fibers were acting strongly, while others were not contracting at all. In other words, there was partial, instead of general atony ; one or more patches, limp and flabby, prolapse into some part of the globular arch of the contracting organ, and thus form the dimple so generally supposed to be necessary as a start toward inversion. The vehemence of contraction which this intruding portion would cause, is recognized by most writers as sufficient to complete the displacement. This state of partial atony must occupy fibers partially paralyzed by some circum- stance existing during gestation, or occurring at the time of labor. In the case of Dr. Sawyer, reported with so much intelligence and minuteness, the condition of the uterus anterior to delivery was sufficient to account' for a weakened state of the fibers. There was a very considerable dropsy of the chorion, and the uterus contained an extraordinary amount of liquor amnii. This fact, interpreted, means that the fibers were stretched. In normal pregnancy the uterine fibers are not stretched ; the whole organ is hypertrophied, and the actual addition of tissue, or growth of the muscles of the uterus, form a receptacle for the ovum that contracts uniformly and with vigor for the expulsion of its con- tents. Now, if an abnormal amount of fluid is secreted, it is accommodated not by a further increase of the muscular tissue forming the uterine globe, but the organ is distended, and the muscular wall becomes thinner by the distension. Thus stretched and thinned, for perhaps weeks before confinement, the fibers become weaker, and the labors succeeding this state of things are INVERSIO PARTIALIS UTERI PUERPERALIS. precisely the kind described by Dr. Sawyer. The contractions are painful and inefficient, the fibers acting discordantly until the foetus is expelled or removed, as it was in this case. It is almost certain that the efficiency of some portions of the fibers is more impaired than that of others. It is well known that in uteri thus over-distended we have the hour-glass contraction — the incomplete contraction — accompanied by.haemorrhage, etc., and why not also inversion ? If the ergot had any injurious influence in the reported case, it was not in causing the inversion, but in rendering the fibers more resistent to efforts at reposition. Dr. Byford further said that the treatment instituted by Dr. Sawyer was such as would sug- gest itself to most intelligent obstetricians. It was quite apparent, however, from the tenor of the discus- sion to-night, as well as the diverse theories of inversion promul- gated by writers on obstetrics, that there is yet much to be learned in reference to this most interesting subject. With reference to the cause of death, he thought there could be no doubt but that it was due to shock, and the haemorrhage was not sufficient to contribute materially to that end. In ex- pressing this opinion, he would remind the society that the over- whelming influence of shock upon the nervous system depended as much upon the incapacity of certain persons to rally from ner- vous depression, as upon the force of the causing influence. What would kill some persons would not, on account of the inscrutable elasticity possessed by others, have any effect upon them. Dr. Sawyer: I feel indebted to the Fellows for the full and very intelligent discussion which my report has elicited, as well as for the very charitable willingness which has been shown to exonerate me from responsibility in the unfortunate termination of the case. The only point which was raised in my mind upon reflection, was concerning the administration of ergot; not that its use in any degree caused the inversion; there is not one fact which could suggest such a presumption, but that the condition of tonic spasm of the uterus, which prevented the immediate reduc- tion of the displaced organ, might have been excited by the drug. I am assured, however, by the remarks which have been made, that such a spasm might have been induced by the presence of CHICAGO GYNAECOLOGICAL SOCIETY. the fundus in the cavity of the uterus. In this they are con- firmed by no less an authority than W. Tyler Smith, a reference to whom has been made in my report. The remark made by Prof. Miller, viz: that the fundus may be indented by the tips of the fingers, when compression of the uterus is injudiciously made, I hold to be of paramount import- ance. In this connection I may be permitted to allude to the dangers attending Crc-de’s method of expressing the placenta. In using this method, we are instructed to seize the uterus in both hands, and to squeeze out the after-birth. Practically one does not compress the uterus uniformly in all its axes ; the abdominal parietes render the posterior surface of the organ inaccessible, and the tips of the fingers are forced to press upon the fundus. Nowq under certain conditions, is it not reasonable to suppose that the paralyzed fundus may be indented in this manner ? In fact, I have no question but that, in the case under discussion, the point of departure was in the compression which was used under my direction. The plan of compressing the abdominal aorta from within the uterine cavity, alluded to by Dr. Nelson, has long found a place in the literature of the subject, and is spoken of by Cazeaux. IVhen the uterus is large, the procedure has the advantage claimed for it, namely, that of quickly recognizing any descent of the fundus. But it is an agonizing operation. Moreover, in order to compress the artery, the hand must be carried above the fourth lumbar vertebra, or nearly to the umbilicus, and this interferes with the proper retraction of the uterus. On this account, I give prefer- ence to compression through the abdominal parietes. Concerning the cause of puerperal inversion, all observers have remarked that unusual distension of the uterus, as exists in some cases of multiple pregnancy, and in drops}7 of the amnion, is a condition which favors the accident. But upon the initial step in the process of inversion, the profession seems divided. One class of observers hold that it is a condition of irregular contrac- tion of the uterus, whereby it is inverted; in other words, that the process is an active one in its very beginning. Prof. Byford has very clearly given us the modus operandi of this process, for which he has expressed his preference. It is especially dwTelt INVERSIO PARTIALIS UTERI PUERPERALIS upon by W. Tyler Smith, its author, who has likened the process to inversion and intussusception of the intestine, upon the one hand, and speaks of its relations to spasmodic rigidity of the os uteri, and so-called hour-glass contraction with retention of the placenta. It may be said, in support of the active process, that the virgin uterus has been known to Invert itself by unceasing contraction of the organ. Another class of observers believe the first step in the process to be passive, so far as the uterus is concerned, and that the fundus falls into the body by its own weight, or is pushed, or drawn down- ward through some external force. I am impelled to accept the latter as correct. It is true that I can only speak upon the authority of a single case, but it will be conceded that the opportunity for observation was as good as it was rare. At a given moment, I felt the outlines of the sym- metrical but flaccid uterus, its fundus reaching nearly to the um- bilicus. Shortly afterward, the organ had contracted, and its fundus was gone. Now, what occurred in that short interval ? Of course positive knowledge is precluded, because the fundus of the uterus cannot be inspected, and my hand was not in the cavity of the organ. Bnt of one thing I feel convinced, namely, that there was no contraction, partial or complete, of the uterus be- fore the fundus had fallen. In reality, the recognition of the con- traction and the discovery of the absence of the fundus were sim- ultaneous. From this moment, however, till the last, the uterus was in a state of tonic spasm. Had the victim survived the shock, I can easily understand how this contraction may have propelled the fundus, and have made the inversion complete. There is one other condition which I think can have an influ- ence in determining this accident. Dr. Merriman has called our attention to a predisposing cause laid down by Barnes, namely, the location of the placenta at the fundus. I desire • to ask the Fellows if it ever occurred to them that the location of the pla- centa at the fundus is extremely infrequent, quite as accidental, and, it may be, as rare as its location in the cervical zone? Per- haps in this fact Dr. Jackson, and others, may find one explana- tion of the great rarity of puerperal inversion of the uterus. I CHICAGO GYNAECOLOGICAL SOCIETY. have many times determined the location of the placenta, through the uterine souffle, but have never yet found the area of the great- est intensity of the souffle to be at the highest part of the uterus. I regret that the location was not ascertained in the case before us. The usual site of the placenta, in the right or left lateral half of the uterus, upon its anterior or posterior wall, 1 hold is not a matter of chance, but is determined by a condition of the uterus which obtains in the very earliest days of pregnancy.— You will recall that when the impregnated ovule reaches the cav- ity of the uterus, it finds the lining of the organ, the decidua, so swollen that the walls of the uterus are in apposition, and no cav- ity can be said to exist. Observation has shown, however, that the nearest approach to an unoccupied space within the uterus, is at the superior angles of the organ. When the ovum escapes the uterine opening of the Fallopian tube, it is not impelled to insin- uate itself between the apposed deciduae, but attaches itself natur- ally at the upper angle of the body, where, as we have just seen, there is the most room. It is the attachment of the ovum which determines the location of the placenta. After the third month of pregnancy, the fundus of the uterus contributes most in forming the increasing cavity of the body. So disproportionate is this growth that, at the end of pregnancy, the Fallopian tubes seem to be attached to the uterus in its lower third, instead of near the superior point, as in the unimpregnated state. The placental site remains the same, and though it may increase in size by its own growth, it can never be carried up- ward by the gradual ascent of the fundus. I am aware that when the empty uterus contracts upon itself after delivery, the highest border of the uterus very nearly approaches the placental site ; still then the greatest portion of the latter will be inferior to a line drawn between the uterine opening of the Fallopian tubes. If my reasoning is well founded, the conservative design of nature must be acknowledged ; for we are told by Barnes that a momentary paralysis of the placental site usually exists after labor, and Prof. Miller has said that the uterine tissue is thicker and heavier at that point. I cannot but think that this paralyzed, heavy area would very frequently descend from its normal plane, INVERSIO PARTIALIS UTERI PUERPERALIS 29 if the site were at the highest part of the uterus. But, grace to the fact that the site is mostly upon the side of the spheroid, its tendency is to fall outward. I am not aware that these views have been expressed by others, but I have held and communicated them to my class for three years, and have confirmed the observation concerning the usual site of the placenta by many auscultatory examinations. I desire again to thank the society for the interest which has been shown in the subject and specimen introduced by me.
