【摘要】 目的 探讨热性惊厥(FC)患儿异常脑电图(EEG)与临床特征的关系,以及和以后FC的再发及移行为癫痫(EP)发作的关系。方法 记录158例6个月～6岁患儿FC后EEG。结果 EEG异常率与性别无关;3岁以后首发FC的EEG异常率较3岁以内的高;FC再发者EEG异常率较首次FC发作者高;FC大多发生于体温≥38.5℃,但初发体温<38.5℃,EEG异常发生率明显增高;局灶性发作和FC发作持续时间≥15min者的EEG异常率较全身性发作及发作持续时间<15min者高;有阳性家族史者EEG异常率明显升高。其中有6例FC经过2～5年的随访,最后诊断为EP。结论 FC患者EEG的异常率与阳性家族史及临床特征有明显关系,EEG对FC的早期分类诊断和进行预防性治疗有指导意义。
