作者对３６名肝硬化患者进行了脑诱发电位（ＥＰ）的检测，其中检查视觉诱发电位（ＶＥＰ）２３例，脑干听觉诱发电位（ＢＡＥＰ）３２例，正中神经体感诱发电位（ＳＥＰＳ）２２例，有３３例同时进行了数字连接试验（ＮＣＴ），３０及３６例分别检查了血氨及脑电图。结果表明３０例无肝性脑病（ＨＥ）表现的患者有１８例（６０％）出现三项ＥＰ中任一项以上的异常，部分伴有ＮＣＴ时间的延长，其异常率与肝功能损害的程度有关，而血氨及脑电图（ＥＥＧ）与正常对照组无明显差异，提示ＥＰ及ＮＣＴ对亚临床型肝性脑病（ＳＨＥ）有一定的诊断意义，而血氨及ＥＥＧ的诊断价值不大。
Thirty-six patients with cirrhosis were evaluated for brain evoked potential (EP). Among them, 23 were visual evoked potential (VEP), 32 were brainstem auditory evoked potential (BAEP), 22 were median nerve somatosensory evoked potential (SEPS) , There were 33 cases of simultaneous digital connectivity test (NCT), 30 and 36 cases of blood ammonia and electroencephalogram were examined. The results showed that in 30 patients with no hepatic encephalopathy (HE), 18 patients (60%) had any one of three EP abnormalities, some were accompanied by the prolongation of NCT, the abnormality rate and the extent of liver dysfunction , While there was no significant difference between blood ammonia and electroencephalogram (EEG) and normal control group, suggesting that EP and NCT have some diagnostic significance for subclinical hepatic encephalopathy (SHE), while the diagnostic values of blood ammonia and EEG are not significant .
