心理测验、视觉诱发电位检测亚临床肝性脑病的价值

探讨心理测验、视觉诱发电位检测在亚临床肝性脑病 (SHE)诊断中的意义。对 4 5例肝硬化患者及 30例正常人进行数字连接试验 (NCT) ,视觉诱发电位 (VEP)检测。研究其在亚临床肝性脑病诊断中的应用价值。肝硬化组NCT异常占 5 6 % (2 5 / 4 5 ) ,VEP异常占 4 9% (2 2 / 4 5 ) ,NCT和 (或 )VEP异常占 71% (32 / 4 5 ) ,两者均异常 33% (15 /4 5 ) ;对照组NCT异常占 30 % (9/ 30 ) ,VEP异常占 2 7% (8/ 30 )。两组比较差异有显著性意义 (P <0 0 5 )。NCT和VEP可用于诊断SHE ,联合检测可提高SHE检出率 ,对预防肝性脑病的发生有重要意义

The value of visual evoked potential and psychometric tests in detection of subclinical hepatic encephalopathy

To investigate the diagnostic values of psychometric test (PT)and visual evoked potential (VEP)in detection of subclinical hepatic encephalopathy (SHE).Number connection test(NCT)and VEP were performed in 45 patients with liver cirrhosis and in 30 healthy subjects as controls respectively.22 patients (49%) were found abnormal with VEP detection and 25 cases (56%)with NCT.In control group,9 cases (30%)were abnormal with NCT and 8 cases (27%) with VEP.The difference was significant in VEP and NCT between the patients group and control group (P<0.05).NCT and VEP were useful in diagnosis of SHE. There was added advantage of performing PT and VEP to detect SHE.
