Abstract
PARALDEHYDE, introduced into medicine by Cervello1 in 1882, rapidly became and has remained one of the most useful hypnotics in medical practice. Its quick, smooth action and relative safety frequently make it the hypnotic of choice in acute excitement and in situations where a quick hypnotic effect is desirable. It is commonly the favorite of the intern because of its wide dose range, quick, apparently physiologic action, freedom from serious toxic effects and uniform efficacy. It is useful for controlling insomnia, excitement, agitation, delirium, convulsions and even severe pain, in which its powerful hypnotic effect leads to relaxation and sleep. . . .
