目的 :探讨睡眠脑电图在小儿癫痫诊断中的意义。方法 :对 1998年 7月～ 1999年 7月疑为癫痫的患儿脑电图进行总结 ,对其中 130例确诊为癫痫的患儿进行自身对照回顾性研究 ,同一患者既作清醒状态脑电图 ,又作睡眠脑电图。睡眠脑电图均在自然或剥夺睡眠状态下进行。出现棘波、尖波、棘慢复合波、尖慢复合波或多棘慢复合波认为脑电图检查阳性。结果 :本年度疑为癫痫患者 6 0 5人次 ,清醒脑电图阳性率36 8% (99/ 2 6 9) ,睡眠脑电图阳性率 5 1 2 % (172 / 336 ) ,睡眠脑电图阳性率较清醒脑电图更高 (χ2 =12 5 ,P =0 0 0 0 4)。 130例中清醒脑电图阳性 38例 ,阳性率 2 9 2 % (38/ 130 ) ,同组患者睡眠脑电图阳性率净增加 92例(即不包括清醒阳性的 38例 ) ,净增 70 8% (92 / 130 )。结论 :睡眠脑电图能明显提高癫痫确诊率 ,疑为癫痫的患儿在作清醒状态脑电图同时应作睡眠脑电图。
Objective: To investigate the significance of sleep EEG in the diagnosis of pediatric epilepsy. Methods: EEGs of children with suspected epilepsy from July 1998 to July 1999 were summarized. A retrospective study of 130 children with epilepsy diagnosed as their own was conducted. The same patients were both treated with conscious electroencephalogram , But also for sleep EEG. Sleep EEG are in nature or sleep deprivation. Spike wave, spike wave, spinous slow complex wave, sharp slow complex wave or spine slow composite wave that EEG positive. Results: The number of patients with epilepsy was 655, the positive rate of sober EEG was 36.8% (99/269), the positive rate of sleep EEG was 52.2% (172/336), and the positive of sleep EEG The rate was higher than that of conscious EEG (χ2 = 125, P = 0 0 0 0 4). Of the 130 patients, 38 were positive in sober EEG, with a positive rate of 292% (38/130). In the same group, the positive rate of sleep EEG was increased by 92 (excluding 38 patients with clear positive), a net increase of 70 8% (92/130). Conclusion: Sleep EEG can significantly improve the diagnosis of epilepsy, suspected of epilepsy in children with awake EEG sleep apnea EEG should be.
