目的：分析癫癎患者脑电图癎样放电的相关因素及临床意义。方法：对用２４ ｈ 便携式磁带记录脑电图（ＡＥＥＧ） 检出癎样放电的１６２ 例癫癎患者进行相关因素分析。结果：在临床表现为全面性发作患者，ＡＥＥＧ 可检出有明确定位价值的颅内局灶性异常。睡眠时期癎样放电检出率为８０ ％ ，癎样放电主要出现于ＮＲＥＭⅠ—Ⅱ期（７９ ％ ） ，清醒期及睡眠期均出现癎样放电的７４ 例患者中其局灶性异常（６７ ％ ） 均出现于睡眠期，癎样放电仅出现于睡眠期患者的ＡＥＥＧ 局灶性异常率为８２ ％ （４５／５５） 。结论：ＡＥＥＧ 对癫癎有重要的诊断价值，对于检出有夜间发作倾向的部分性癫癎的癎样放电意义更大。
Objective: To analyze the related factors and clinical significance of EEG discharge in epileptic patients. Methods: Correlation analysis was performed on 162 epileptic patients with 24 h portable magnetic recording electroencephalography (AEEG). RESULTS: In patients with a complete clinical presentation, AEEG could detect focal intracranial lesions of definite localization. During the sleep period, the positive rate of discharge was 80%. The discharge was mainly in NREMⅠ-Ⅱ (79%), while in the 74 patients in both awake and sleep-like discharges, the abnormality was 67% ) All appeared in the sleep stage. Only 70% of patients with AEEG appeared abnormal discharge rate (82%, 45/55). Conclusion: AEEG has important diagnostic value for epilepsy, and is more meaningful for detecting partial discharge of partial epilepsy with tendency of nocturnal seizures.
