肝硬化患者亚临床肝性脑病的诱发电位检测

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，ＢＡＥＰ和ＳＳＥＰ异常率逐渐增高，分别为Ｃｈｉｌｄ－Ｐｕｇｈ Ａ级４１．７％和８．３％，Ｂ级４

Evoked potentials in diagnosis of subclinical hepatic encephalopathy in cirrhotic patients

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 .
