PRENATAL ANOMALIES. 5 pageefficacy of fetal therapeutics have been made from time to time with varying results.
Gusserow of Strasbourg tested for iodin, chloroform, and salicylic acid in the blood and secretions of the fetus after maternal administration just before death. In 14 cases in which iodin had been administered, he examined the fetal urine of 11 cases; in 5, iodin was present, and in the others, absent. He made some similar experiments on the lower animals. Benicke reports having given salicylic acid just before birth in 25 cases, and in each case finding it in the urine of the child shortly after birth.
At a discussion held in New York some years ago as to the real effect on the fetus of giving narcotics to the mother, Dr. Gaillard Thomas was almost alone in advocating that the effect was quite visible. Fordyce Barker was strongly on the negative side. Henning and Ahlfeld, two German observers, vouch for the opinion of Thomas, and Thornburn states that he has witnessed the effect of nux vomica and strychnin on the fetus shortly after birth. Over fifty years ago, in a memoir on "Placental Phthisis," Sir James Y. Simpson advanced a new idea in the recommendation of potassium chlorate during the latter stages of pregnancy. The efficacy of this suggestion is known, and whether, as Simpson said, it acts by supplying extra oxygen to the blood, or whether the salt itself is conveyed to the fetus, has never been definitely settled.
McClintock, who has been a close observer on this subject, reports some interesting cases. In his first case he tried a mixture of iron perchlorid and potassium chlorate three times a day on a woman who had borne three dead children, with a most successful result. His second case failed, but in a third he was successful by the same medication with a woman who had before borne a dead child. In a fourth case of unsuccessful pregnancy for three consecutive births he was successful. His fifth case was extraordinary: It was that of a woman in her tenth pregnancy, who, with one exception, had always borne a dead child at the seventh or eighth month. The one exception lived a few hours only. Under this treatment he was successful in carrying the woman safely past her time for miscarriage, and had every indication for a normal birth at the time of report. Thornburn believes that the administration of a tonic like strychnin is of benefit to a fetus which, by its feeble heart-beats and movements, is thought to be unhealthy. Porak has recently investigated the passage of substances foreign to the organism through the placenta, and offers an excellent paper on this subject, which is quoted in brief in a contemporary number of Teratologia.
In this important paper, Porak, after giving some historical notes, describes a long series of experiments performed on the guinea-pig in order to investigate the passage of arsenic, copper, lead, mercury, phosphorus, alizarin, atropin, and eserin through the placenta. The placenta shows a real affinity for some toxic substances; in it accumulate copper and mercury, but not lead, and it is therefore through it that the poison reaches the fetus; in addition to its pulmonary, intestinal, and renal functions, it fixes glycogen and acts as an accumulator of poisons, and so resembles in its action the liver; therefore the organs of the fetus possess only a potential activity. The storing up of poisons in the placenta is not so general as the accumulation of them in the liver of the mother. It may be asked if the placenta does not form a barrier to the passage of poisons into the circulation of the fetus; this would seem to be demonstrated by mercury, which was always found in the placenta and never in the fetal organs. In poisoning by lead and copper the accumulation of the poison in the fetal tissues is greater than in the maternal, perhaps from differences in assimilation and disassimilation or from greater diffusion. Whilst it is not an impermeable barrier to the passage of poisons, the placenta offers a varying degree of obstruction: it allows copper and lead to pass easily, arsenic with greater difficulty. The accumulation of toxic substances in the fetus does not follow the same law as in the adult. They diffuse more widely in the fetus. In the adult the liver is the chief accumulatory organ. Arsenic, which in the mother elects to accumulate in the liver, is in the fetus stored up in the skin; copper accumulates in the fetal liver, central nervous system, and sometimes in the skin; lead which is found specially in the maternal liver, but also in the skin, has been observed in the skin, liver, nervous centers, and elsewhere in the fetus. The frequent presence of poisons in the fetal skin demonstrates its physiologic importance. It has probably not a very marked influence on its health. On the contrary, accumulation in the placenta and nerve centers explains the pathogenesis of abortion and the birth of dead fetuses ("mortinatatite") Copper and lead did not cause abortion, but mercury did so in two out of six cases. Arsenic is a powerful abortive agent in the guinea-pig, probably on account of placental hemorrhages. An important deduction is that whilst the placenta is frequently and seriously affected in syphilis, it is also the special seat for the accumulation of mercury. May this not explain its therapeutic action in this disease? The marked accumulation of lead in the central nervous system of the fetus explains the frequency and serious character of saturnine encephalopathic lesions. The presence of arsenic in the fetal skin alone gives an explanation of the therapeutic results of the administration of this substance in skin diseases.
Intrauterine amputations are of interest to the medical man, particularly those cases in which the accident has happened in early pregnancy and the child is born with a very satisfactory and clean stump. Montgomery, in an excellent paper, advances the theory, which is very plausible, that intrauterine amputations are caused by contraction of bands or membranes of organized lymph encircling the limb and producing amputation by the same process of disjunctive atrophy that the surgeons induce by ligature. Weinlechner speaks of a case in which a man devoid of all four extremities was exhibited before the Vienna Medical Society. The amputations were congenital, and on the right side there was a very small stump of the upper arm remaining, admitting the attachment of an artificial apparatus. He was twenty-seven years old, and able to write, to thread a needle, pour water out of a bottle, etc. Cook speaks of a female child born of Indian parents, the fourth birth of a mother twenty-six years old. The child weighed 5 1/2 pounds; the circumference of the head was 14 inches and that of the trunk 13 inches. The upper extremities consisted of perfect shoulder joints, but only 1/4 of each humerus was present. Both sides showed evidences of amputation, the cicatrix on the right side being 1 inch long and on the left 1/4 inch long. The right lower limb was merely a fleshy corpuscle 3/4 inch wide and 1/4 inch long; to the posterior edge was attached a body resembling the little toe of a newly-born infant. On the left side the limb was represented by a fleshy corpuscle 1 inch long and 1/4 inch in circumference, resembling the great toe of an infant. There was no history of shock or injury to the mother. The child presented by the breech, and by the absence of limbs caused much difficulty in diagnosis. The three stages of labor were one and one-half hours, forty-five minutes, and five minutes, respectively. The accompanying illustration shows the appearance of the limbs at the time of report.
Figure 10 represents a negro boy, the victim of intrauterine amputation, who learned to utilize his toes for many purposes. The illustration shows his mode of holding his pen.
There is an instance reported in which a child at full term was born with an amputated arm, and at the age of seventeen the stump was scarcely if at all smaller than the other. Blake speaks of a case of congenital amputation of both the upper extremities. Gillilam a mentions a case that shows the deleterious influence of even the weight of a fetal limb resting on a cord or band. His case was that of a fetus, the product of a miscarriage of traumatic origin; the soft tissues were almost cut through and the bone denuded by the limb resting on one of the two umbilical cords, not encircling it, but in a sling. The cord was deeply imbedded in the tissues.
The coilings of the cord are not limited to compression about the extremities alone, but may even decapitate the head by being firmly wrapped several times about the neck. According to Ballantyne, there is in the treatise De Octimestri Partu, by Hippocrates, a reference to coiling of the umbilical cord round the neck of the fetus. This coiling was, indeed, regarded as one of the dangers of the eighth month, and even the mode of its production is described. It is said that if the cord he extended along one side of the uterus, and the fetus lie more to the other side, then when the culbute is performed the funis must necessarily form a loop round the neck or chest of the infant. If it remain in this position, it is further stated, the mother will suffer later and the fetus will either perish or be born with difficulty. If the Hippocratic writers knew that this coiling is sometimes quite innocuous, they did not in any place state the fact.
The accompanying illustrations show the different ways in which the funis may be coiled, the coils sometimes being as many as 8.
Bizzen mentions an instance in which from strangulation the head of a fetus was in a state of putrefaction, the funis being twice tightly bound around the neck. Cleveland, Cuthbert, and Germain report analogous instances. Matthyssens observed the twisting of the funis about the arm and neck of a fetus the body of which was markedly wasted. There was complete absence of amniotic fluid during labor. Blumenthal presented to the New York Pathological Society an ovum within which the fetus was under going intrauterine decapitation. Buchanan describes a case illustrative of the etiology of spontaneous amputation of limbs in utero Nebinger reports a case of abortion, showing commencing amputation of the left thigh from being encircled by the funis. The death of the fetus was probably due to compression of the cord. Owen mentions an instance in which the left arm and hand of a fetus were found in a state of putrescence from strangulation, the funis being tightly bound around at the upper part. Simpson published an article on spontaneous amputation of the forearm and rudimentary regeneration of the hand in the fetus. Among other contributors to this subject are Avery, Boncour, Brown, Ware, Wrangell, Young, Nettekoven, Martin, Macan, Leopold, Hecker, Gunther, and Friedinger.
Wygodzky finds that the greatest number of coils of the umbilical cord ever found to encircle a fetus are 7 (Baudelocque), 8 (Crede), and 9 (Muller and Gray). His own case was observed this year in Wilna. The patient was a primipara aged twenty. The last period was seen on May 10, 1894. On February 19th the fetal movements suddenly ceased. On the 20th pains set in about two weeks before term. At noon turbid liquor amnii escaped. At 2 P.M., on examination, Wygodzky defined a dead fetus in left occipito-anterior presentation, very high in the inlet. The os was nearly completely dilated, the pains strong. By 4 P.M. the head was hardly engaged in the pelvic cavity. At 7 P.M. it neared the outlet at the height of each pain, but retracted immediately afterward. After 10 P.M. the pains grew weak. At midnight Wygodzky delivered the dead child by expression. Not till then was the cause of delay clear. The funis was very tense and coiled 7 times round the neck and once round the left shoulder; there was also a distinct knot. It measured over 65 inches in length. The fetus was a male, slightly macerated. It weighed over 5 pounds, and was easily delivered entire after division and unwinding of the funis. No marks remained on the neck. The placenta followed ten minutes later and, so far as naked-eye experience indicated, seemed healthy.
Intrauterine fractures are occasionally seen, but are generally the results of traumatism or of some extraordinary muscular efforts on the part of the mother. A blow on the abdomen or a fall may cause them. The most interesting cases are those in which the fractures are multiple and the causes unknown. Spontaneous fetal fractures have been discussed thoroughly, and the reader is referred to any responsible text-book for the theories of causation. Atkinson, De Luna, and Keller report intrauterine fractures of the clavicle. Filippi contributes an extensive paper on the medicolegal aspect of a case of intrauterine fracture of the os cranium. Braun of Vienna reports a case of intrauterine fracture of the humerus and femur. Rodrigue describes a case of fracture and dislocation of the humerus of a fetus in utero. Gaultier reports an instance of fracture of both femora intrauterine. Stanley, Vanderveer, and Young cite instances of intrauterine fracture of the thigh; in the case of Stanley the fracture occurred during the last week of gestation, and there was rapid union of the fragments during lactation. Danyau, Proudfoot, and Smith mention intrauterine fracture of the tibia; in Proudfoot's case there was congenital talipes talus.
Dolbeau describes an instance in which multiple fractures were found in a fetus, some of which were evidently postpartum, while others were assuredly antepartum. Hirschfeld describes a fetus showing congenital multiple fractures. Gross speaks of a wonderful case of Chaupier in which no less than 113 fractures were discovered in a child at birth. It survived twenty-four hours, and at the postmortem examination it was found that some were already solid, some uniting, whilst others were recent. It often happens that the intrauterine fracture is well united at birth. There seems to be a peculiar predisposition of the bones to fracture in the cases in which the fractures are multiple and the cause is not apparent.
The results to the fetus of injuries to the pregnant mother are most diversified. In some instances the marvelous escape of any serious consequences of one or both is almost incredible, while in others the slightest injury is fatal. Guillemont cites the instance of a woman who was killed by a stroke of lightning, but whose fetus was saved; while Fabricius Hildanus describes a case in which there was perforation of the head, fracture of the skull, and a wound of the groin, due to sudden starting and agony of terror of the mother. Here there was not the slightest history of any external violence.
It is a well-known fact that injuries to the pregnant mother show visible effects on the person of the fetus. The older writers kept a careful record of the anomalous and extraordinary injuries of this character and of their effects. Brendelius tells us of hemorrhage from the mouth and nose of the fetus occasioned by the fall of the mother; Buchner mentions a case of fracture of the cranium from fright of the mother; Reuther describes a contusion of the os sacrum and abdomen in the mother from a fall, with fracture of the arm and leg of the fetus from the same cause; Sachse speaks of a fractured tibia in a fetus, caused by a fall of the mother; Slevogt relates an instance of rupture of the abdomen of a fetus by a fall of the mother; the Ephemerides contains accounts of injuries to the fetus of this nature, and among others mentions a stake as having been thrust into a fetus in utero; Verduc offers several examples, one a dislocation of the fetal foot from a maternal fall; Plocquet gives an instance of fractured femur; Walther describes a case of dislocation of the vertebrae from a fall; and there is also a case of a fractured fetal vertebra from a maternal fall. There is recorded a fetal scalp injury, together with clotted blood in the hair, after a fall of the mother: Autenrieth describes a wound of the pregnant uterus, which had no fatal issue, and there is also another similar case on record.
The modern records are much more interesting and wonderful on this subject than the older ones. Richardson speaks of a woman falling down a few weeks before her delivery. Her pelvis was roomy and the birth was easy; but the infant was found to have extensive wounds on the back, reaching from the 3d dorsal vertebra across the scapula, along the back of the humerus, to within a short distance of the elbow. Part of these wounds were cicatrized and part still granulating, which shows that the process of reparation is as active in utero as elsewhere.
Injuries about the genitalia would naturally be expected to exercise some active influence on the uterine contents; but there are many instances reported in which the escape of injury is marvelous. Gibb speaks of a woman, about eight months pregnant, who fell across a chair, lacerating her genitals and causing an escape of liquor amnii. There was regeneration of this fluid and delivery beyond term. The labor was tedious and took place two and a half months after the accident. The mother and the female child did well. Purcell reports death in a pregnant woman from contused wound of the vulva. Morland relates an instance of a woman in the fifth month of her second pregnancy, who fell on the roof of a woodshed by slipping from one of the steps by which she ascended to the roof, in the act of hanging out some clothes to dry. She suffered a wound on the internal surface of the left nympha 1 1/2 inch long and 1/2 inch deep. She had lost about three quarts of blood, and had applied ashes to the vagina to stop the bleeding. She made a recovery by the twelfth day, and the fetal sounds were plainly audible. Cullingworth speaks of a woman who, during a quarrel with her husband, was pushed away and fell between two chairs, knocking one of them over, and causing a trivial wound one inch long in the vagina, close to the entrance. She screamed, there was a gush of blood, and she soon died. The uterus contained a fetus three or four months old, with the membranes intact, the maternal death being due to the varicosity of the pregnant pudenda, the slight injury being sufficient to produce fatal hemorrhage. Carhart describes the case of a pregnant woman, who, while in the stooping position, milking a cow, was impaled through the vagina by another cow. The child was born seven days later, with its skull crushed by the cow's horn. The horn had entered the vagina, carrying the clothing with it.
There are some marvelous cases of recovery and noninterference with pregnancy after injuries from horns of cattle. Corey speaks of a woman of thirty-five, three months pregnant, weighing 135 pounds, who was horned by a cow through the abdominal parietes near the hypogastric region; she was lifted into the air, carried, and tossed on the ground by the infuriated animal. There was a wound consisting of a ragged rent from above the os pubis, extending obliquely to the left and upward, through which protruded the great omentum, the descending and transverse colon, most of the small intestines, as well as the pyloric extremity of the stomach. The great omentum was mangled and comminuted, and bore two lacerations of two inches each. The intestines and stomach were not injured, but there was considerable extravasation of blood into the abdominal cavity. The intestines were cleansed and an unsuccessful attempt was made to replace them. The intestines remained outside of the body for two hours, and the great omentum was carefully spread out over the chest to prevent interference with the efforts to return the intestines. The patient remained conscious and calm throughout; finally deep anesthesia was produced by ether and chloroform, three and a half hours after the accident, and in twenty minutes the intestines were all replaced in the abdominal cavity. The edges were pared, sutured, and the wound dressed. The woman was placed in bed, on the right side, and morphin was administered. The sutures were removed on the ninth day, and the wound had healed except at the point of penetration. The woman was discharged twenty days after, and, incredible to relate, was delivered of a well-developed, full-term child just two hundred and two days from the time of the accident. Both the mother and child did well.
Luce speaks of a pregnant woman who was horned in the lower part of the abdomen by a cow, and had a subsequent protrusion of the intestines through the wound. After some minor complications, the wound healed fourteen weeks after the accident, and the woman was confined in natural labor of a healthy, vigorous child. In this case no blood was found on the cow's horn, and the clothing was not torn, so that the wound must have been made by the side of the horn striking the greatly distended abdomen.
Richard, quoted also by Tiffany, speaks of a woman, twenty-two, who fell in a dark cellar with some empty bottles in her hand, suffering a wound in the abdomen 2 inches above the navel on the left side 8 cm. long. Through this wound a mass of intestines, the size of a man's head, protruded. Both the mother and the child made a good convalescence. Harris cites the instance of a woman of thirty, a multipara, six months pregnant, who was gored by a cow; her intestines and omentum protruded through the rip and the uterus was bruised. There was rapid recovery and delivery at term. Wetmore of Illinois saw a woman who in the summer of 1860, when about six months pregnant, was gored by a cow, and the large intestine and the omentum protruded through the wound. Three hours after the injury she was found swathed in rags wet with a compound solution of whiskey and camphor, with a decoction of tobacco. The intestines were cold to the touch and dirty, but were washed and replaced. The abdomen was sewed up with a darning needle and black linen thread; the woman recovered and bore a healthy child at the full maturity of her gestation. Crowdace speaks of a female pauper, six months pregnant, who was attacked by a buffalo, and suffered a wound about 1 1/2 inch long and 1/2 inch wide just above the umbilicus. Through this small opening 19 inches of intestine protruded. The woman recovered, and the fetal heart-beats could be readily auscultated.
Major accidents in pregnant women are often followed by the happiest results. There seems to be no limit to what the pregnant uterus can successfully endure. Tiffany, who has collected some statistics on this subject, as well as on operations successfully performed during pregnancy, which will be considered later, quotes the account of a woman of twenty-seven, eight months pregnant, who was almost buried under a clay wall. She received terrible wounds about the head, 32 sutures being used in this location alone. Subsequently she was confined, easily bore a perfectly normal female child, and both did well. Sibois describes the case of a woman weighing 190 pounds, who fell on her head from the top of a wall from 10 to 12 feet high. For several hours she exhibited symptoms of fracture of the base of the skull, and the case was so diagnosed; fourteen hours after the accident she was perfectly conscious and suffered terrible pain about the head, neck, and shoulders. Two days later an ovum of about twenty days was expelled, and seven months after she was delivered of a healthy boy weighing 10 1/2 pounds. She had therefore lost after the accident one-half of a double conception.
Verrier has collected the results of traumatism during pregnancy, and summarizes 61 cases. Prowzowsky cites the instance of a patient in the eighth month of her first pregnancy who was wounded by many pieces of lead pipe fired from a gun but a few feet distant. Neither the patient nor the child suffered materially from the accident, and gestation proceeded; the child died on the fourth day after birth without apparent cause. Milner records an instance of remarkable tolerance of injury in a pregnant woman. During her six months of pregnancy the patient was accidentally shot through the abdominal cavity and lower part of the thorax. The missile penetrated the central tendon of the diaphragm and lodged in the lung. The injury was limited by localized pneumonia and peritonitis, and the wound was drained through the lung by free expectoration. Recovery ensued, the patient giving birth to a healthy child sixteen weeks later. Belin mentions a stab-wound in a pregnant woman from which a considerable portion of the epiploon protruded. Sloughing ensued, but the patient made a good recovery, gestation not being interrupted. Fancon describes the case of a woman who had an injury to the knee requiring drainage. She was attacked by erysipelas, which spread over the whole body with the exception of the head and neck; yet her pregnancy was uninterrupted and recovery ensued. Fancon also speaks of a girl of nineteen, frightened by her lover, who threatened to stab her, who jumped from a second-story window. For three days after the fall she had a slight bloody flow from the vulva. Although she was six months pregnant there was no interruption of the normal course of gestation.
Bancroft speaks of a woman who, being mistaken for a burglar, was shot by her husband with a 44-caliber bullet. The missile entered the second and third ribs an inch from the sternum, passed through the right lung, and escaped at the inferior angle of the scapula, about three inches below the spine; after leaving her body it went through a pine door. She suffered much hemorrhage and shock, but made a fair recovery at the end of four weeks, though pregnant with her first child at the seventh month. At full term she was delivered by foot-presentation of a healthy boy. The mother at the time of report was healthy and free from cough, and was nursing her babe, which was strong and bright.
All the cases do not have as happy an issue as most of the foregoing ones, though in some the results are not so bad as might be expected. A German female, thirty-six, while in the sixth month of pregnancy, fell and struck her abdomen on a tub. She was delivered of a normal living child, with the exception that the helix of the left ear was pushed anteriorly, and had, in its middle, a deep incision, which also traversed the antihelix and the tragus, and continued over the cheek Date: 2014-12-29; view: 779
