Diarrhœa is sometimes an exceedingly troublesome symptom during pregnancy. It not only weakens the patient and thus tends indirectly to induce abortion by destroying the life of the fœtus, but it acts also in a more direct manner by exciting uterine contractions, particularly when accompanied, as is frequently the case, with tenesmus. The diarrhœa which is met with in pregnant women is not so frequently, as has been supposed, the result of irritation from the uterus, producing simply an increased peristaltic action of the bowels without any considerable derangement of their functions; by far the most usual form is connected with a very deranged state of the alimentary canal; the evacuations are offensive and generally very acrid; the liver is torbid or secretes an unhealthy bile, so that at length a state approaching to dysentery is produced. Even if the patient go to the full term of utero-gestation, she is much reduced, and is ill able to make those exertions which will be required during labour. If the motions, though frequent, are scanty in proportion to the ingesta, or if scybala are occasionally expelled, one or two doses of castor oil will be required; a few drops of Liq. Opii Sedativ. may be added with advantage to allay the irritability of the bowels, after which, equal parts of blue pill, or Hydr. c. Cretâ, and Dover’s powder, will excite the liver to a healthier action, and still farther control their inordinate activity. If the disposition to tenesmus be troublesome, a small injection of starch and opium will afford relief. If the stomach will bear it, a rice-milk diet for a day or two is desirable; it is a gentle demulcent to the irritable intestines, and has a slightly constipating effect.
Pruritus pudendi to a very distressing degree occasionally comes on during pregnancy, and though in most instances a very manageable form of disease, yet if its nature be not properly understood it proves exceedingly obstinate, and much suffering is the result. It appears to be essentially different from the common prurigo, being an aphthous state of the lining membrane of the vagina and skin which covers the perineum and external organs. There is great heat and redness of the parts, which are more or less swollen, and from the scratching which the intense itching demands, the cuticle, where it has been raised by the pustules, becomes abraided, so that severe excoriations, and, where there has not been sufficient attention to cleanliness, even ulcerations may be produced. The pustules on the external parts frequently attain a considerable size, being more distinct than in the vagina, which is usually incrusted with one confluent mass of aphthæ; whereas, on the perineum and margins of the labia we have seen them as large as peas. These cases for the most part yield to the tepid Goulard lotion, or solution of borax.
Where the patient is plethoric, and the system in a state of considerable excitement from the irritation, blood-letting will be necessary, followed by cooling saline laxatives; and if there be much inflammation of the parts, leeches will prove of great service. In every case the bowels ought to be attended to, for constipation will greatly increase the inflammation, and the obstinacy of the disease. It is to Dr. Dewees that we are indebted for first pointing out the real cause and nature of this troublesome affection.[46]
Aphthæ of the vagina are not unfrequently met with in cases of uterine disease, where the discharge is extremely acrid, but the prominent symptom, viz. the intense pruritus, is absent. The aphthous vagina of pregnancy is not a common affection.
Salivation is another affection which is occasionally, though rarely, met with in pregnancy. It is usually attended with morning sickness, constant nausea, and deranged bowels, and may reduce the patient excessively: attention to the state of the bowels, followed by gentle alteratives and tonics, generally gives relief.
