目的探讨剥夺睡眠诱发试验对癫痫的诊断价值。方法对180例临床诊断为癫痫的患儿进行常规脑电图和剥夺睡眠脑电图,比较两者痫样放电率及与癫痫类型的关系。结果与常规脑电图比较剥夺睡眠脑电图可提高脑电图痫样放电率(痫样放电率从30%提高到76%,P<0.01)。并观察到精神运动性癫痫阳性率高。结论剥夺睡眠脑电图可明显提高痫样放电检出率,应作为癫痫患儿的常规检查。
Objective To investigate the diagnostic value of sleep deprivation-induced test on epilepsy. Methods 180 cases of clinical diagnosis of epilepsy in children with routine electroencephalogram and deprivation sleep EEG, epileptiform discharge rate and the relationship between the type of epilepsy. Results Compared with conventional electroencephalography, sleep deprivation electroencephalogram improved the EEG discharge rate (epileptiform discharge rate increased from 30% to 76%, P <0.01). And observed the high rate of motor-positive seizures. Conclusion Sleep deprivation electroencephalography can significantly improve the detection rate of epileptiform discharge, should be used as routine examination in children with epilepsy.
