脑电图在肝性脑病早期诊断中的作用评价

目的探讨脑电图(electroencephalogram,EEG)监测在肝性脑病(hepaticencephalopathy,HE)早期诊断中的价值。方法180例child肝功能分级均为C级、无明显脑病症状的肝硬化患者均进行EEG描记分析,根据EEG结果分为EEG明显异常,即广泛轻—中度异常组(A组)和EEG无异常或边缘性异常组(B组);随访观察两组HE的发病情况。结果180例肝硬化患者中,A组有114例,其中并发HE者11例;B组有66例,其中并发HE者2例。A组HE的发生率明显高于B组(P<0.05)。结论EEG在HE的早期诊断中具有重要价值。

Early diagnostic value of electroencephalogram is hepatic encephalopathy

Objective To evaluate the early diagnosis value of electroencephalogram(EEG) in hepatic encephalopathy(HE). Methods All the 180 cirrhosis patients without HE symptom whose liver function ranked as level Caccording to Child-pugh's standard received EEG examination and there after divided into Group A(widely mild to moderate abnormal EEG) and Group B(normal or marginal EEG).The incidence of HE in Group A and Group B was compared with each other.Results Among the 180 cirrhosis patients, there 11 HE patients in Group A(114/180) and only 2 HE patients in Group B(66/180). The HE incidence in Group A was higher than that in Group B(P<0.05).Conclusions EEG played an important role in the early diagnosis of HE.
