Objective:Discussion on the EEG and its relation with clinical characteristic in children with febrile convulsions.Methods:We analyzed retrospectively the relationship among the clinical manifestation, evolution and abnomal electroencephalogram in 95 children with febrile convulsion. Results:The abnormality rate of EEG was 32.63%in one-two week;The EEG abnormality rate in children with the relapse times of FC and age under three years was significantly higher ,which in children with low body temperature was ignificantly higher than that in children with high body temperature and statistics significance is exist. 73 cases were simple FC,22 were complicated FC. The abnormality rate of EEG with epilepsy was 3.82% ,27.28%. Conclusion:The indidence of EEG is related with sex and the abnormality rate is interrelated with age,recurrent FC and body temperature. Complicated FC is easy to develop into epilepsy.% 目的：探讨小儿热性惊厥(febrile convulsions, FC)脑电图(electroencephalogram, EEG)特点与临床的关系.方法：回顾性分析93例热性惊厥患儿临床表现及EEG 特点.结果：93例患儿发作后1-2周后EEG 异常率为32.63%；按年龄分组其中<3岁组及抽搐反复发作组异常率高；高热惊厥组及低热惊厥组EEG有显著性差异.73例表现为单纯性热惊厥,22例表现为复杂性热惊厥,EEG出现痫样放电的异常率分别是3.82%、27.28%.结论：EEG 发生率与性别相关；EEG异常率与年龄、抽搐时体温、发作次数等有关.复杂性热惊厥转为癫痫的可能性大.
