• Two children showed evidence of alpha-pattern coma (APC). One case followed a phenobarbital sodium overdose with complete recovery. The second case occurred subsequent to cardiopulmonary arrest with unfavorable outcome. These cases and others that we reviewed emphasize that the prognosis of APC in children, as in adults, is variable and appears to be related to the cause.
