检查了25例肝硬化患者脑干听觉、视觉及体感诱发电位(BAEP、VEP、SEP).结果显示B、C级肝硬化及肝昏迷患者BAEP的Ⅲ,Ⅴ波潜伏期及Ⅰ—Ⅲ、Ⅰ—Ⅴ波间潜伏期,VEP的P_(100)波潜伏期,SEP的P_(40)、N_(50)、P_(60)及N_(75)波潜伏期延长,且随病情加重而渐延长,P_(10c)波潜伏期表现最明显。A级肝硬化患者已存在VEP及SEP的异常。表明肝硬化患者在发生临床肝昏迷之前已存在脑电活动异常,VEP可反映肝硬化的严重程度.SEP则是一较敏感的指标。
The brainstem auditory, visual and somatosensory evoked potentials (BAEP, VEP, SEP) were examined in 25 patients with cirrhosis.The results showed that the latency of Ⅲ and Ⅴ waves of BAEP in patients with cirrhosis and hepatic coma and the latency of Ⅰ-Ⅲ and Ⅰ- The incubation period of V wave, P_ (100) wave latency of VEP and the latency of P_ (40), N_ (50), P_ (60) and N_ (75) waves of SEP were prolonged and gradually increased with the increase of P_ ) The most obvious wave latency performance. Patients with grade A cirrhosis have abnormal VEP and SEP. It shows that there are EEG abnormalities in cirrhotic patients before clinical hepatic coma and VEP can reflect the severity of cirrhosis.SEP is a sensitive index.
