In cases where the gastritis is both acute and persistent, in which nausea and vomiting are incessant, and the weakness of the patient progressive, it may be necessary in order to give the stomach rest, and at the same time to maintain the strength, to resort to nutrient enemata. In using these two important things must be borne in mind, namely that the absorbent powers of the mucous membrane of the rectum are slight and slow, and also that irritation may easily be set up. The foods selected for nutrient enemata should be, therefore, easily absorbed and bland. It has been found by experiment that albumen, peptones, starch, and fat in the form of an emulsion, are all absorbable in the rectum. It is well, however, to administer the albumens and starch predigested, and hence peptonised beef-tea and peptonised milk gruel, or maltine with peptonised milk, are the most useful foods for rectal alimentation. Not more than from one to three ounces should be injected at the time, warmed to the temperature of the body. A long tube carefully oiled should be used, and to obtain the best results the rectum should be washed out with lukewarm water an hour before the enema is administered (Yeo). In cases where more solid food can be retained and absorbed in the rectum, Leube's meat and pancreatic paste may be injected. This is made by mincing two to four ounces of meat with a half to one ounce of fresh pancreas free from fat. Pestle in a mortar with a small amount of lukewarm water till the whole is reduced to a smooth paste, of a consistence sufficiently fluid to pass up the tube of the enema. It should be injected warm. Life cannot be maintained for long on nutrient enemata, and their continued use may provoke obstinate diarrhoea; but they may prove of great value in cases of acute gastritis or of ulcer of the stomach, when it is of the utmost importance to give the stomach absolute rest while still maintaining the strength of the patient.
