剥夺睡眠脑电图在小儿癫痫诊断中的价值

Value of Electroencephalogram(EEG) after Depriving Sleep in the Diagnosis of Epilepsy

目的探讨剥夺睡眠脑电图在小儿癫痫诊断中的价值。方法剥夺患儿睡眠使其在进行脑电图描记时较快进入自然睡眠,然后与清醒状态下描记的脑电图比较痫样放电的阳性率。结果两种状态下描记的脑电图痫样放电的阳性率分别为71.05%和30.95%,经卡方检验,差异有非常显著性(χ2=12.83,P<0.01)。结论剥夺睡眠描记的脑电图是提高癫痫诊断水平简单易行的方法。

[ Objective] To explore the value of electroencephalogram （ EEG） after depriving sleep in the diagnosis ot epilepsy. [Methods] The children were deprived of sleep before taking the EEG in order to enable them to fail asleep spontaneously while taking EEG. The EEG record was compared with that taken when they were awake to get the positive rate of epileptiform discharges. [Results] The positive rate of epileptiform discharges in the two situations were 71.05% and 30.95% respectively, the difference was significant （X^2 = 12.83, P 〈 0.01）. [ Conclusion] Electroencephalogram （EEG） after depriving sleep is a simple and practical method to diagnose epilepsy.
