In any case, the patient should be put to bed and fed carefully every two or three hours on milk, peptonized food or barley water. If this is not retained, albumin water may be given for twenty-four hours at regular intervals, or rectal alimentation may be tried after stopping all foods by mouth. Iced champagne, seltzer or Vichy, either alone or with milk, may be tried. A dry diet is sometimes effective, rusk, toast, toasted shredded wheat biscuit, crackers, etc., taken early in the morning, as one eats cheese. No exercise is permitted except such muscular and nervous excitation as may be derived from massage or the sedative bath. Drugs are sometimes of great value—the bromides, in full doses, or 1 m. doses of tincture of iodine, well diluted, every hour; or bismuth with hydrocyanic acid; or cocaine or oxalate of cerium. Occasionally good results are reported from a capsule of pepsin, 2 gr. and ¼ gr. silver nitrate given just before meals; and adrenalin in 10 drop doses may be considered. Extract of corpus lutea has been tried by Hirst with favorable results. Sinapisms to the epigastrium and ice bags to the spine have been found useful, and washing out the stomach is efficient at times. In washing out the stomach, be sure the stomach tube is _iced_ before it is introduced. When the case gets worse in spite of treatment and acidosis supervenes, bicarbonate of soda may be given in sixty grain doses every four hours, by rectum, if necessary, until the urine gives an alkaline reaction. Glucose as a readily assimilable carbohydrate may be given in doses up to 10 oz. of a 6 per cent solution (Eden) or sugar infusions by rectum, 1000 c.c. in twenty-four hours by drop method. _The obstetric treatment_ is the emptying of the uterus. To be effective the abortion must be done before the condition of the patient is desperate. It is most favorable before the febrile stage. If the vomiting persists in spite of treatment and is accompanied by emaciation, a pulse of over 100, albumin in the urine, with an increase of the ammonia output, the pregnancy should be terminated at once. If the patient can not go to a hospital, the nurse should prepare the room as described for operations. After emptying the uterus, the vomiting usually ceases but much labor is thrown upon the nurse in supplying nourishment and caring for an exhausted and whimsical patient. The back must be inspected daily for decubitus (bed sores) and her position changed frequently. A daily rub with alcohol and water (50 per cent) followed by an oil inunction will be valuable. The teeth and gums should be cleaned with gauze, wrapped around the finger and dipped in solution of boric acid. No brush should be used. [Illustration: Fig. 29.—Twins.
