摘　　要：目的探讨热性惊厥患儿脑电图异常率与热性惊厥复发、日后癫痫发作的关系。方法回顾性分析196例热性惊厥患儿的临床表现、预后与脑电图异常的关系,并探讨影响热性惊厥患儿继发癫痫(EP)的危险因素。结果本组196例患儿EEG正常118例(60.20%),异常78例(39.80%)。EEG异常率与患者年龄、惊厥家族史、发热温度、热性惊厥类型、发作类型、发作次数及惊厥持续时间有密切关系(P<0.01)。196例患儿有78例(39.80%)复发,8例(4.08%)转为癫痫。脑电图异常组热性惊厥复发频率高于正常组,但差异无统计学意义(P>0.05),两组癫痫发生率差异有统计学意义(P<0.01)。结论脑电图对观察热性惊厥患儿的脑功能状态、预后评估及早期发现癫痫有重要价值。Objective To study the relationship between the abnormal rate of electroencephalogram （EEG） and the relapse of febrile convulsion （FC） and later epileptic seizure. Methods We retrospectively analyzed the relationship among the clinical manifestations,evolution,and abnormal electroencephalogram in 196 children with febrile convulsion. And the risk factors of secondary epilepsy were detected. Results The normal rate and the abnormal rate of EEG were 60.20% （118/196） and 39.8% （78/196）,respectively. The abnormal rate of EEG was closely related to age,family history with epilepsy,fever temperature,FC type,type of spasm,frequency of FC,and duration of FC （P0.01）. There were 78 cases （39.80%） to recur,and 8 cases （4.08%） to turn to epilepsy. The recrudescence of FC in abnormal EEG group was higher than that in normal EEG group and no statistically significant difference was found between the two groups （P0.05）. There were statistically significant differences in the incidence rate of epilepsy between the two groups （P0.01）. Conclusions Electroencephalogram may be of great value to early diagnosis of epilepsy,judgment of brain function,and prognosis of FC.
