摘要
目的： 评价脑诱发电位（ＥＰ） 诊断亚临床型肝性脑病（ＳＨＥ） 的价值。方法： 对４８ 例肝炎后肝硬化患者进行三种ＥＰ检查， 并追踪１年观察临床肝性脑病（ＨＥ） 出现情况。结果： 三种脑诱发电位总异常２６例（５４％ ），其中听觉诱发电位 （ＢＡＥＰ） 异常１８例 （３８％ ）、视觉诱发电位（ＶＥＰ） 异常３ 例（６％ ）、体感诱发电位 （ＳＥＰ） 异常１０ 例 （２１％ ）， 以ＢＡＥＰ异常率最高。追踪观察１ 年的２９例患者中， １５例ＥＰ异常者出现ＨＥ１１ 例 （７３％ ）， 无ＥＰ异常１４例中， 出现ＨＥ４ 例（２８％ ） （Ｐ＜ ０．０５）。结论： 揭示ＢＡＥＰ对诊断ＳＨＥ最敏感， 同时三种ＥＰ检查可提高ＳＨＥ的检出率，
Objective: To explore the value of evoked potentials (EP) in early detection of subclinical hepatic encephalopathy (SHE) Methods: Evoked potentials were performed in 48 patients with liver cirrhosis and patients were followed up for one year for development of overt hepatic encephalopathy (HE) Results: Evoked potentials were abnormal in 26(54%) patients, 18(38%) with abnormal brainstem evoked potential (BAEP) 3(6%) with abnormal, visual evoked potential (VEP) in 3(6%) and 10(21%) with abnormal somatosensory evoked potential(SEP) Among 29 cases followed up for one year, 11 of 15(73%) with abnormal evoked potential developed HE, compared to 4 of 14 (28%)with normal evoked potential ( P <0 05) Conclusions: There was added advantage of performing three kinds of EP at the same time for improved detection of SHE, which helps to predict the development of HE
