The duration and severity of the attacks vary widely. Some patients are very ill and for a long time, even requiring an abortion before showing signs of improvement, while others recover in a few days if wisely managed. If a patient once suffers from neurotic vomiting, she is very likely to have it in subsequent pregnancies, particularly if the circumstances of her life remain unaltered. =Toxemic vomiting= is regarded by some doctors as a very grave and very rare complication of pregnancy, which is usually fatal; by others as simply a severe form of the very common “morning sickness,” which they believe is always toxic, no matter how mild; while still others, as already stated, doubt the occurrence of such a condition as toxemic vomiting of pregnancy. I mention these differences of opinion in order that the nurse may be aware of their existence and be prepared to adjust herself whole-heartedly to the different methods of treatment for which they are responsible. For no matter what else may vary, the earnestness and sincerity of the nurse’s attitude must be a veritable Gibralter of reliability. The chief =symptoms= of toxemic vomiting, in addition to persistent vomiting, as described by those who recognize its occurrence, are coffee-ground vomitus; a diminished amount of urine, possibly containing albumen, acetone bodies and casts; coma and sometimes convulsions. The disease may run its course swiftly and the patient die in a week or ten days, or it may persist less acutely for weeks, in which case there is extreme emaciation and prostration. In those cases which come to autopsy there is a definite and characteristic, central necrosis of the liver lobule. The =treatment= and nursing care vary widely because so little is definitely known about the cause, and because of the varieties of theories concerning it which are held by different obstetricians. Some believe that prompt emptying of the uterus is about the only course which is effective, while others feel that because of the probable toxicity of the patient it is advisable also to stimulate all of the excretory organs. Accordingly, they give free purges, colonic irrigations, hot packs and copious amounts of sugar and saline solution by mouth, rectum, intravenously and by infusion. Corpus luteum, too, is sometimes given hypodermically two or three times weekly. Although this treatment is not in universal use or favor, some patients seem to be given absolute relief by its administration.
