为评价心理测验和脑诱发电位检查诊断亚临床型肝性脑病 (SHE)的价值 ,对 36例肝炎肝硬化患者进行心理测验和三种脑诱发电位 (EP)检查 ,并追踪 1年观察临床肝性脑病 (HE)出现情况。结果心理测验异常 16例(42 % ) ,EP总异常为 18例 (5 0 % )。心理测验和 /或诱发电位异常 2 8例 (77% ) ,两者均异常者为 11例 (31% % )。追踪观察 1年的 34例患者中 ,2 6例心理测验和 /或脑诱发电位异常者出现临床肝性脑病 19例 (73% ) ,无心理测验和 /或脑诱发电位检查异常 8例中 ,出现临床肝性脑病 2例 (2 5 % ) (P <0 0 5 )。结果表明同时进行心理测验和脑诱发电位检查可提高SHE检出率 ,检测SHE对预测肝性脑病的发生有临床价值
To assess the value of psychometric tests and brain evoked potentials in the diagnosis of subclinical hepatic encephalopathy (SHE), 36 patients with cirrhosis of the liver were subjected to psychological tests and three kinds of brain evoked potential (EP) tests and followed up for 1 year to observe clinical liver Encephalopathy (HE) occurs. Results Sixteen patients (42%) had abnormal psychological tests, and 18 patients (50%) had total EP abnormalities. There were 28 cases (77%) of psychological tests and / or evoked potentials abnormalities, 11 cases (31%) of them were abnormal. Of the 34 patients who observed for 1 year, 26 (73%) had clinical hepatic encephalopathy in 26 patients with abnormal psychological tests and / or brain evoked potentials. Of the 8 patients who did not have psychological tests and / or abnormal evoked potentials of brain evoked potentials, There were 2 cases of clinical hepatic encephalopathy (25%) (P <0 05). The results show that both psychological tests and brain evoked potential test can increase the detection rate of SHE, SHE on the prediction of the occurrence of hepatic encephalopathy has clinical value
