Outcome of coma in children.

Coma following a hypoxic-ischemic event is a serious condition and common reason for admission to the pediatric intensive care unit. Because coma has a high rate of mortality and morbidity in children, and the clinician may be unsure of the outcome very early in the course, it is important to have strategies to define prognosis. Although most studies have been conducted in adults, we review factors predicting outcome from coma of nontraumatic causes in infants and children. We consider the relation between physical findings, commonly accessible laboratory tools, and outcome, and comment on some newer techniques that may become more available for clinical purposes.
