脑电图对肝硬化合并肝性脑病的诊断价值分析

摘要

Objective To explore the value of electroencephalogram (EEG) in the diagnosis of liver cirrhosis complicated with hepatic encephalopathy.Methods A total of 78 patients with liver cirrhosis complicated with hepatic encephalopathy admitted by the authors were selected and received EEG examination.The abnormal performance of EEG was observed and the relation between abnormal degree and stage of encephalopathy and Child-Pugh stage analyzed.Results All of the 78 patients had abnormal EEG;the mild group had no lethargy or coma cases.The constituent ratio of patients with lethargy or coma (100％) in the severe group was higher than that (35％) in the moderate group.There was significant difference among the three groups (P ＜ 0.05).The constituent ratio (6.3％) of Grade C (Child-Pugh grade) patients in the mild group was lower than that in the moderate group (52.5％) and the severe group (66.7％);the difference among the three groups was significant (P ＜ 0.05).Conclusion The abnormal degree of EEG can reflect the clinical staging and Child-Pugh stage of liver cirrhosis complicated with hepatic encephalopathy and has significant reference value in clinical diagnosis.%目的 探讨脑电图对肝硬化合并肝性脑病的诊断价值.方法 选取笔者收治的78例肝硬化合并肝性脑病患者,均行脑电图检查,观察其脑电图异常表现情况,并分析异常程度与脑病分期及Child-Pugh分级之间的关系.结果 78例均存在脑电图异常;轻度组无昏睡和昏迷患者,重度组昏睡期和昏迷期患者构成比(100％)高于中度组(35％),3组间比较均有显著性差异(P＜0.05);轻度组Child-Pugh分级C级患者的构成比(6.3％)低于中度组(52.5％)和重度(66.7％)组,3组间比较也均有显著性差异(P＜0.05).结论 脑电图异常程度可反映肝硬化合并肝性脑病患者的临床分期及Child-Pugh肝功能分级,对临床诊断具有重要的参考价值.
