肝硬变患者视觉诱发电位变化与肝性脑病的关系

RELATIONSHIP BETWEEN CHANGE IN VISUAL EVOKED POTENTIALS AND ONSET OF HEPATOENCEPHALOPATHY IN PATIENTS WITH CIRRHOSIS

本文对肝硬变患者33例进行了视觉诱发电位(VEP)测定,并与50名健康混合年龄组(其峰值8.74±3.43μV,峰时85.1±5.02ms)进行对照。结果:33例中峰值正常者12例,降低者20例(60.6％)。峰时延长者15例(45.5％)。结果反映肝硬变患者VEP有较大改变。测定VEP的变化有益于肝性脑病的早期诊断。

Visual evoked potentials (VEPs) were recorded in 33 patients with cirrhosis and 50 healthy subjects.The peak value was 8.74±3.43μV and the peak time 85.1±5.02 ms in the healthy group.Of 33.cirrhotics,the peak value in 18 cases was low and the peak time of 15 cases was prolonged as compared with those of the healthy controls.The results suggest that measurement of VEPS might be useful for early diagnosis of hepatoencephalopathy.
