開頭術直後痙攣の臨床的検討

Clinical Analysis of Immediate Postoperative Convulsion

I．はじめに

　われわれは術後痙攣の予防法を確立する目的で，先に破裂脳動脈瘤術後長期観察例における術後晩期痙攣について検討を加えた^2）が，今回は術後早期，特に術後24時間以内に起こる痙攣（これを外傷直後痙攣にならって，術直後痙攣と呼ぶ）について臨床例を対象に検討を加えたので，その頻度，臨床的特徴ならびにCT所見について報告する．

For the prevention and treatment of immediatepostoperative convulsion which develops within 24 hours after neurosurgical operation, clinical analysis of consecutive 1293 cases in Kyoto University Hospi-tal was done. Overall incidence was 3.1% and the incidence was highest in supratentorial craniotomy (5.7%). Previous history of convulsion was not con-tributory. In 77.5% of cases, the convulsion was developed within 6 hours after operation and focal convulsion was more often than the generalized one. Status epilepticus was often developed. Theincidence of convulsion was well correlated to the level of consciousness.
