小儿高热惊厥临床与脑电图特征

THE CLINICAL AND EEG FEATURES ON CHILDREN WITH FEBRILE CONVULSION

目的:观察小儿热性惊厥发病年龄、症状、脑电图表现及小儿热性惊厥预后的脑电图表现。方法:对2007年～2012年80例小儿高热惊厥从发热当时、热退后1周、10天时分别进行脑电图检查,观察脑电图演变,从特征上并结合惊厥发作的次数、发作的年龄、发作持续的时间来预判断病情可能的发展方向。结果:发作当时EEG异常率80%,1周35%,10天25%。异常表现为高波幅慢波异常者11例,出现散在、局限性慢波异常者6例,呈棘-尖-慢复合波者3例。结论:高热惊厥患儿临床及脑电图演变有一定的规律,可根据这个规律在临床上早期判断病情的发展方向。

Objective：To observe the age of onset,symptoms,change of EEG of children with febrile convulsion and change of EEG of prognosis. Methods： From 2007 to 2012,EEG of 80 patients with febrile convulsion were examined respectively at that time of heating,a week and 10 days after the fever has gone. The EEG evolution was observed from the characteristics and combined with the number of attack, the age,the duration of attack to judge preliminarily direction of development of the disease. Results： The abnormal rate of EEG was 80% in attack,35% in a week and 25% in 10 days. In abnormal change,11 cases were slow wave of high amplitude,6 cases were scattered limitations slow wave,3 cases were spike and sharp slow-wave complex. Conclusion： In children with febrile convulsion,clinical and EEG evolution has certain rule. According to this rule we may determine the direction of development of the disease in the early stage.
