Givena case of valvular disease that must be subjected to operation, thechances are better with an anesthetic, as the pain and mental shockare worse for the heart than is the anesthetic. (See SuprarenalGland.) Untoward Effects and their Treatment.—Vomiting after the use ofchloroform develops in about 15 per cent, of cases. Alarming effectsproduced by this drug are far more apt to appear in males than infemales, the relative proportion being about 6 to 1. Sometimesduring the administration of chloroform the heart or respirationsuddenly ceases, and in some cases this change is preceded by apeculiar shade or cloud which passes over the face of the patient; butdeath may come suddenly and without warning. If untoward effectsappear, the anesthetic must be at once withdrawn and artificialrespiration resorted to. Injections of ether and brandy should be.
