151例儿童发作性疾病的24h动态脑电图监测

目的对儿童发作性疾病的脑电活动进行分析。方法对１５１例发作性疾病儿童应用２４ｈ便携式磁带记录脑电图（ＡＥＥＧ）进行监测。结果总异常率８０８％，痫样放电出现率７９５％。癫痫组痫样放电出现率７８８％，可疑癫痫组痫样放电出现率４５５％，两组之间有非常显著差异（Ｐ＜０００５）。ＡＥＥＧ痫样放电出现率明显高于常规脑电图（ＥＥＧ）；癫痫组与可疑癫痫组之间临床发作中所描记到的痫样放电出现率也有非常显著差异（Ｐ＜００１）。本组病人的痫样放电部位以全脑或一侧，或限局性一侧偏胜者多见，痫样放电时间以睡眠时期为主占７４２％，其中６７７％见于浅睡期。结论２４ｈ动态脑电图监测对于儿童发作性疾病的诊断有着非常重要的意义。

Twenty-four-hour ambulatory EEG monitoring in 151 children with paroxysmal disorder.

Objectives To analyse the clinical significance of AEEG in the children with paroxysmal disorder. Methods The 24-hour AEEG was monitored in the 151 children with paroxysmal disorder. Results Total abnormality rate of AEEG was 80.8%,and the epileptiform discharges was 79.5%.The epileptiform discharge was 78.8% in the epileptic group,and that was 45.5% in the suspected epileptic group.There was significant difference (P <0.005) betwen two groups.The detectability rate of epileptiform discharges by AEEG was higher than that by EEG.During clinical attack,the difference was also significant (P <0.001) about epilptiform discharges between the epileptic group and the suspected group.The abnormal waves were mostly seen on the total brain,or a lateral,or to be dominated on a lateral.The time of epileptiform discharges were mainly during sleep (74.2%). Conclusions AEEG is of important value to the diagnosis of children with paroxysmal disorder.
