Evaluation of the Comatose Patient

Abstract

The authors discuss the value of a prepared methodical plan of action in evaluating the comatose patient. They stress the importance of first recognizing and correcting any respiratory or circulatory failure, and then thoroughly assessing the history and results of physical examination. Laboratory tests which are likely to yield maximal information in the shortest possible time while causing the least discomfort to the patient should be selected. The finding of an obvious abnormality early in the evaluation does not justify an incomplete appraisal since other diseases may be coexistent, particularly if the coma has been present for considerable time. Timely discovery of the cause of coma often will permit institution of lifesaving therapy.
