【摘要】 目的了解不同严重程度肝硬化患者亚临床肝性脑病的发生率及其临床意义。方法对３０例无临床肝性脑病的肝炎后肝硬化患者同时进行脑干听觉、视觉和短潜伏期体感诱发电位（ＢＡＥＰ、ＶＥＰ、ＳＳＥＰ）检测。结果三种脑诱发电位检测以ＢＡＥＰ异常率（４６．７％）高于 ＶＥＰ和 ＳＳＥＰ（均为 ３６．７％）；随着肝病程度加重，ＢＭ和 ＳＳＥＰ异常率逐渐增高，分别为 Ｃｈｉｌｄ－ Ｐｕｇｈ Ａ级４１．７％和８３％，Ｂ级４６．７％和４６．７％，Ｃ级６６．７％和１００％，而ＶＥＰ则无此倾向。三种脑诱发电位异常的形式主要为波峰潜伏期延迟和波峰消失。结论脑诱发电位检测有助于肝硬化患者亚临床肝性脑病的诊断及预后判断，对临床肝性脑病的预防亦有一定的指导意义。更多还原

【Abstract】 Aim To evaluate the prevalence of subclinical hepatic encephalopathy (SHE) in hospitalized cirrhotic patients with different seventy. Method Brain stem auditory, visual and short -- latency so,aomatosensory evoked potentials (BAEP, VEP, SSEP) were examined in 30 cirrhotic patients without overt hepatic encephalopathy. Results The abnormality was more frequently detected by BAEP (46. 7% ) than by VEP and SSEP (both were 36. 7% ). The abnormal rates were correlated with the seventy of the liver disease in BAEP and SSEP: Child - Pugh class A patients were 41. 7% and 8. 3 %, class B patients both were 46 .7%, and class C patients were 66. 7% and 100%, respectively. But, there was no such tendency in VEP. The Main forms of abnormality were prolonged latency of the waves or decreased, even disappeard amplitudes. Conclusion Exdrination of brain evoked potentials is helpful for the detection of SHE and estimation of the prognosis in cirrhotic patients .更多还原
