287例热性惊厥患儿的脑电图分析

EEG analysis of 287 children with febrile seizures

目的:探讨热性惊厥(FS)患儿的脑电图特征.为临床诊断及治疗提供参考。方法:对航空总医院2016~2019年进行脑电图检查的287例FS患儿的2h高清视频脑电图予以回顾性分析。结果:男176例(61.3%),女111例(38.7%)。高发年龄为1~3岁。正常脑电图164例.正常率为57.1%.异常脑电图74例,异常率为25.8%.界线性脑电图49例,界线率为17.1%。FS患儿74例异常脑电图中,发作间期痫样放电为额区放电18例,颞区放电4例.枕区放电19例,Rolandic区放电13例,广泛脑区放电20例。结论:脑电图对评价FS后的患儿是否持续存在脑波异常及脑功能损害有临床指导意义。

Objective:To detect the characteristics of electroencephalogram(EEG)of children with febrile seizures(FS)so as to provide reference for clinical diagnosis and treatment of FS.Methods:The 2-hour high-definition video EEG records of 287 children with FS from 2016 to 2019 in Beijing Aviation General Hospital were retrospectively analyzed.Results:There were 164 cases with normal EEG,(the normal rate:57.1%);74 cases with abnormal EEG,(the abnormal rate:25.8%),and 49 cases with borderline EEG,(the borderline rate:17.1%).Boys accounted for 61.3%and girls for 38.7%.The highest incidence age is 1~3 years old.Among 74 children with FS,the epileptiform discharges in interphase were as follows;18 in frontal area,4 in temporal area,19 in occipital area,13 in Rolandic area and 20 in extensive brain area.Conclusion:EEG is of clinical significance in evaluating continuous abnormal EEG and brain function damages in children with FS.
