[Value of the EEG in the prognosis of post-anoxic coma following cardiocirculatory arrest].
The EEGs of 26 patients who remained at least 6 hours in coma after cardiovascular arrest were analyzed. The first EEG was recorded within few days after reanimation, classified in a 5-grade scale of increasingly severe impairment and compared with the final clinical outcome. ⋯ Grade II and III findings have no definite prognosis: the EEG should be repeated one or two days later, a favorable outcome is to be expected only with rapid improvement of the tracing. Grade IV and Grade V findings have a very serious prognosis: complete recovery has been described episodically, most in the pediatric population and with findings of alpha-coma.
