ABSTRACT

Objective To study the value of P 300 in judging the true and false coma in patients with closed craniocerebral trauma. Methods The latency and amplitude of abnormal P 300 evoked by visual (image) stimulation were compared and analyzed between 237 cases with closed craniocerebral trauma.which were divided into coma,non coma,false coma and noclear group.Results There was very remarkable diffe rence in the latency and amplitude of P 300 between coma group and non coma group ( P 0 05). There was remarkable difference between the cases whose coma histories were unclear and non coma ( P
