Causes. Prominent among these are injuries which have been inflicted upon the intestines, compression of the colon, or rectum, perforation of the stomach or bowels, either by violence or some pre-existing disease, thus allowing the discharge of blood, urine, bile, or fecal matter into the abdominal cavity; also abortion, over-exertion, and exposure to wet or cold. As acute peritonitis is always a grave disease, involving more or less danger to life, it is the wisest course to employ a physician and trust the case to his management. The same remark is equally applicable to the chronic form of the disease.
Chronic Peritonitis. Like the acute, it may be either circumscribed or general. This form is sometimes, though rarely, a sequel of the acute. When it appears independently of the acute, it is generally associated with some cutaneous affection pertaining to the abdominal cavity, and the inflammation is induced by the tumor. If chronic peritonitis be connected with the tubercular diathesis, tubercles may be discovered upon the surface of the stomach and alimentary canal, and may also be found in the lungs and brain.
When the affection is not tubercular there will appear in the abdominal cavity an effusion of serous fluid of greater or less quantity, mingled with blood and pus. When such an effusion takes place, the abdomen gradually increases in size, or becomes smaller than is natural. There is pain, attended by soreness upon pressure, and the patient becomes emaciated.
Inflammation of the peritoneum is frequently an accompaniment of puerperal fever, which is a disease peculiar to childbirth, and which may arise from cold, or be communicated from one parturient patient to another by midwives.
Treatment. In the remedial management of acute peritonitis, it is obviously necessary to use some agent which will at once influence and change the congested state and inflammatory condition. One of the best agents employed to make a decided impression upon the vascular system, subdue inflammation, and modify its action, is the fluid extract of veratrum viride, administered in full doses, and repeated until the system shows its effects in a decided manner. Warm fomentations applied to the abdomen are sometimes very serviceable, and are objectionable only because of their liability to dampen the bed-clothes. When the abdomen will bear a thick, warm poultice, apply it, and then cover the entire surface with oiled silk. The tincture of opium, in doses sufficient to relieve pain and quiet the peristaltic action of the intestines, is generally necessary.
EPIDEMIC CHOLERA.
This is an epidemic disease, supposed to be due to an impalpable specific poison, but as to the exact nature of this poisonous matter nothing definite is known.
This plague first made its appearance on our continent in 1834. Owing to its great fatality, it is a disease much to be dreaded.
Symptoms. These are well defined. It is characterized in its earlier stages by pain in the stomach and bowels, especially in the umbilical region, nausea, vomiting, diarrhea; later, the purging is excessive, and the matter dejected resembles rice-water, and contains white, solid, curd-like matter. The patient loses strength, and sinks rapidly. The secretory organs fail to perform their functions normally, the skin is sometimes moist, but oftener cold and dry; but little if any bile is found in the excretions, and the urine voided is very scanty. There is general nervous derangement, as indicated by the spasmodic contraction or cramping of the muscles. This first attacks the extremities, but soon affects the entire body, and gives rise to excruciating pains. The head is affected by singing, roaring, disagreeable noises in the ears, the pulse is feeble, but quick, the nails are of a bluish color, the tongue is coated white, the eyes are sunken, and the patient has a corpse-like appearance; the temperature of the body rapidly falls, the surface becomes deathly cold, and, unless the disease is promptly arrested in its course, speedy dissolution follows. The disease is rarely prolonged beyond twenty-four hours, and sometimes terminates within three or four hours after its first attack.
Treatment. The kind of medicine required depends upon the severity of the attack and stage of the disease. In all cholera epidemics, there are premonitory symptoms, such, as an uneasy sensation at the pit of the stomach, and a rumbling of the bowels. This is apt to be followed by a painless diarrhea, which occasions no alarm, and the patient pays but little attention to it. Herein is the great and dangerous mistake. The patient is already in the stage of invasion, which must be promptly arrested, or he will suddenly be precipitated into the stage of collapse. The patient should lie down, and have placed about him bottles filled with hot water, thereby exciting warmth upon the surface of the body. At the same time, administer two teaspoonfuls of the Extract of Smart-weed. If the symptoms are urgent, repeat the dose every fifteen minutes. Brandy, thickened with sugar, may also be given. In either the stage of invasion or collapse, the leading indication is to establish reaction by promoting perspiration. Bathe the feet in water as hot as can be borne, give the Extract of Swart-weed freely, and thus endeavor to excite profuse diaphoresis. No time should be lost, for delays are dangerous. When the reaction is established, the patient should remain quiet, and not attempt to exert himself.
