HABITUAL MISCARRIAGE.—Experience teaches that women who have had one miscarriage must be more careful than other prospective mothers if they would escape a repetition of the accident. Persons who know themselves to be subject to miscarriage should regard no precaution as too burdensome. Not only should they avoid motoring, driving, railroad journeys, sea voyages, and every kind of strenuous exertion, they must accept every opportunity to be quiet and rest. Often such hygienic care yields sufficient protection; but occasionally medicine is also necessary.

A number of causes are at hand to explain habitual miscarriage, but, in fairness, it must be acknowledged that physicians are not able to interpret all cases. With one class of patients the muscle fibers of the womb are peculiarly irritable, whereas in another its lining proves incapable of firmly anchoring the ovum. Moreover, derangements of organs which do not belong to the reproductive group may be responsible for the habit.

It is a curious fact that the accident is most likely to occur when menstruation would be expected were the individual not pregnant. Obviously, extraordinary precaution is advisable at such times, and if the patient would avoid even the slightest risk, she should not leave her bed. The same purpose will not be served by sitting quietly in a chair, nor by reclining on a couch; complete relaxation and composure are secured only when one lies flat on the back, loosely attired in sleeping garments. I have known several persons with a tendency toward miscarriage who overcame it in this way. Recently one of them who had been delivered prematurely on two former occasions, and who was anxious for a successful issue to her third pregnancy, was willing to remain in bed practically the whole period of gestation. She had her reward; a well-developed infant was born at full term, and has continued to thrive.

Prolonged rest in bed, some will say, is debilitating. While that may be true to a degree, untoward effects can always be avoided by systematic massage of the extremities. The abdomen should not be subjected to such manipulations, for they will occasionally provoke painful contractions of the uterus and defeat the purpose of staying in bed.

Patients who are not disposed to undergo a long period of enforced rest, no matter what profit may be promised, should at least consent to keep in bed during that period of pregnancy at which a previous miscarriage took place. We know that the event is particularly apt to recur at such a time. Specifically, it is important to remain in bed one week before and one week after the date in question.

When pregnancies follow one another in rapid succession, the liability to miscarriage is notably increased. A natural interval between births has been provided, an interval which depends upon the mother nursing her child. Ideally, menstruation, and with it the ripening of the ova (egg-cells), does not occur while the breasts are active; but when the infant does not suckle, the ovaries regularly resume their function in a very short time. Since the circumstances attending miscarriage always deprive the mother of the opportunity of nursing, another pregnancy may quickly ensue unless these facts are appreciated.

Those who anticipate the possibility of a premature interruption of pregnancy should realize that the marital relation is inadvisable after conception has taken place. For others, who have no reason to expect irregularity in the course of pregnancy, such a precaution is unnecessary. None the less, women who marry late in life or who first conceive toward the time of the menopause will do well to follow the same rule. The risk of accident may be very slight, but conservative persons will not assume it when the likelihood of subsequent conception is doubtful.

Not infrequently the fundamental reason for habitual miscarriage lies in some anatomical abnormality which a surgical operation alone can correct. As the necessity for interference can be determined only after a careful examination, recommendations of wide application are not possible. Nothing short of painstaking study of each case will afford a basis for advice and action.

SYMPTOMS.—Very definite warning usually precedes a miscarriage, but the threatening symptoms vary greatly in severity and duration. If appropriate measures are taken promptly, these symptoms may disappear with no harmful result Everyone concedes that bleeding and pain are the chief indications of impending miscarriage, although an occasional patient, profiting by former experience, may find other signs prophetic in her own case.

Mature women, accustomed to the regular monthly function of their sex, are prone to treat with indifference a slight discharge of blood occurring during pregnancy. Indeed, it is widely believed that menstruation frequently continues after conception. In point of fact, however, it is very unusual in early pregnancy, and becomes entirely impossible after the fourth month. Accordingly, whenever vaginal bleeding is noticed, some other explanation should be sought; and the patient who would adopt the wisest plan should assume that she is threatened with miscarriage. There are other possibilities, but these are for her doctor to consider.
