儿童颅脑外伤后癫疒间发作的脑电图及其随访

目的探讨儿童被家长击打头部后癫疒间发作的脑电图及随访脑电图的变化。 方法商丘市第二人民医院于1990-1999年，对36例头部被家长击打后癫疒间发作患儿行脑电图检查并进行3~8年的随访。 结果36例中脑电图异常32例(889%)，其中有疒间样放电者28例(875%,28/32)；随访脑电图异常消失22例(687%,22/32)，疒间样放电消失18例(643%，18/28)。常规记录即有疒间样放电、背景节律以慢波为主、临床发作较晚(>1周)者疒间样放电较难消失(均P<005)。首次脑电图有疒间样放电者临床发作较难控制(P<005)，随访脑电图疒间样放电不消失者临床发作更难控制(P<001)。 结论儿童头部被家长击打后癫疒间发作的脑电图异常率高，疒间样放电消失与否与疒间样放电的特点及临床发作早晚有一定关系，且对临床预后产生较大影响，应引起重视。

The epileptic seizure EEG of the children's heads hit by parents and the follow up.

To investigate the EEG which causes epileptic seizure after children's heads are hit by parents and the following changes. MethodsFrom 1990 to 1999,we recorded EEG of 36 cases of the children's heads hit by parents and epileptic seizure.We followed them for three to eight years. ResultsAmong the 36 cases there were 32 abnormal cases(889%).Among them there were 28 epileptiform discharge(875%,28/32).When we followed them up,we found there were 22 abnormal disappearance(687%,22/32) and 18 epileptiform discharge disappearance(643%,18/28).It was hard to make the epileptiform discharge disappear for the patients whose routine tracing had epileptiform discharge,background activity(slow wave) and epileptic seizure mach later ( >1week ) ( P<005).It was very difficult to control the epileptic seizure which contained the epileptiform discharge in the first EEG(P<005).It was more difficult to control the epileptic seizure whose epileptiform discharge didn't disappear in the EEG (P<001). ConclusionThe abnormal rate of the EEG is very high when the children's heads are hit by parents,which causes epileptic seizure.The epileptiform discharge appearance or disappearance is connected to the its features and the time when it causes epileptic seizure.And it affects the clinical prognosis deeply.We must attach importance to it.
