Eclampsia is a very grave complication of pregnancy, and it was formerly supposed to be uraemia. The disease is characterized by convulsions, loss of consciousness, and coma. It occurs, commonly, in the second half of gestation, but it has been observed as early as the third month. About 70 to 80 per centum of the cases are in primiparous women. The convulsions may come on altogether unexpectedly, but commonly the attack begins with symptoms of toxaemia. Eclampsia may occur before, during, or after parturition. When it comes before term it usually ends in spontaneous or artificial abortion, but at times the woman dies undelivered. Now and then she may recover and be delivered at term.
The kidneys are usually affected, even in those cases in which albuminous urine is not found. There is also a hemorrhagic inflammation of the liver; and oedema and congestion of the brain, with or without apoplexy, are other symptoms of the disease. There are other lesions, but the chief are in the kidneys, liver, and brain.
The aetiology of the disease is not yet known, and there are very many theories offered to explain it. The prognosis is always serious, and the condition is one of the most dangerous found in pregnancy. The mortality varies, but it is about from 20 to 25 per centum in the women, and from 33 to 50 per centum in the children. It is impossible to determine [{53}] the prognosis in particular cases, but a large number of quickly recurring convulsive seizures, with a weak, thready pulse, and a high temperature usually indicate a fatal ending. Apoplexy, oedema of the lungs, and paralysis also, as a rule, end in death.
If the uterus is emptied during the convulsions, these cease either immediately or soon after delivery, in from 66 to 93 per centum of the cases, and the maternal mortality then is about 11 per centum. With the expectant treatment, in convulsive cases, about 28 per centum of the women die, although a use of aconite in these cases may better the prognosis.
Pernicious vomiting (hyperemesis gravidarum) is another complication of pregnancy, which sometimes results fatally if the uterus is not emptied. There are cases, especially those with high fever, which end in death despite all treatment. Here, again, the aetiology of the disease is not known. There is commonly an element of hysteria in the condition, and in such a case moral suggestion often has a curative effect Any bodily irritation is to be removed. Eye-strain alone is enough to cause persistent vomiting. It is very difficult to decide when premature labour is absolutely indicated, because some very bad cases recover spontaneously when all hope is lost.
Hydramnios, or an excessive quantity of liquor amnii, may so distend the uterus as to cause grave danger to maternal life, and if the child is viable the uterus should be emptied.
Intrauterine hemorrhage brought on by a premature separation of the placenta is a very dangerous condition: 32 to 50 per centum of the mothers die, and 85 to 94 per centum of the children. In a marked hemorrhage the only way to save the mother is to empty the uterus, so that it may contract and thus close the patulous vessels.
Placenta praevia is a placenta implanted in the neighbourhood of the internal os of the uterine neck. This is a very perilous condition, calling for the induction of premature labour. The medical treatment is artificial abortion as soon as the condition is diagnosed in any stage of gestation; but this is, of course, in conflict with the decrees of the Holy Office. Under expectant treatment about 40 per centum of [{54}] the mothers die, and 66 per centum of the children. Those children that are born alive commonly die within ten days after delivery. The great foetal mortality is due to premature birth and asphyxiation. Skilful obstetricians get much better results, but skilful obstetricians are unfortunately rare.
When the grave complications enumerated above occur in the early months of pregnancy, before the foetus is viable, the Catholic physician, since by the natural law and the decisions of the Holy Office he is forbidden to induce artificial abortion, must withdraw from the case. If there is no other physician to attend to the woman, he must let her die. He can not withdraw without explanation, and in many cases the explanation of the condition will promptly result in the calling in of a physician who has no scruple in inducing this abortion, no matter how reputable he may be. The universal medical doctrine is to induce abortion in cases where abortion will save the mother's life and the foetus is "too young to amount to anything." This is looked upon as legitimate abortion by the very best men that do not recognise the authority of the Holy Office: they deem the position of the Catholic physician in these cases as altogether erroneous, or even criminal.
The position of the Catholic moralists on craniotomy has turned the attention of many non-Catholic physicians to the immorality of the act, which formerly was deemed entirely permissible. Probably the same good result will be effected in the matter of abortion.
