22例肝硬化病人按Pugh-Child方法分为A,B,C级。每例病人均给予诱发电位检查(包括视觉诱发电位、脑干听觉诱发电位和体感诱发电位),并检查了30例正常人作为对照。结果表明,与正常对照相比,A级病人都有视觉诱发电位VEP的异常(P<0.05),随着肝硬化程度的加重,异常程度更为显著(P<0.001),而脑干听觉诱发电位和体感诱发电位与正常对照比较仅有轻度改变,所以视觉诱发电位对早期肝硬化的诊断及肝功能的判断有一定意义。
Twenty-two patients with cirrhosis were divided into A, B and C according to Pugh-Child method. Each patient was given evoked potentials (including visual evoked potential, brainstem auditory evoked potentials and somatosensory evoked potentials), and examined 30 normal subjects as a control. The results showed that compared with the normal control group, patients with grade A had abnormal visual evoked potential (VEP) (P <0.05), with more severe cirrhosis (P <0.001), and brainstem auditory evoked Potential and somatosensory evoked potentials compared with the normal control only mild changes, so the visual evoked potential of the early diagnosis of cirrhosis and liver function has some significance.
