摘　　要：对３０例慢性呼吸衰竭的肺心病患者、２０例肺炎患者及３０例正常人同时进行脑干听觉、体感诱发电位检查。结果：肺心病组两种诱发电位异常率分别为８０％和８３％；肺炎组为２０％和２０％，经统计学检验，肺心病组较肺炎组有显著性差异（Ｐ＜０．０１）。认为诱发电位可作为慢性呼吸衰竭的肺心病患者脑功能障碍的敏感电生理指标，对肺性脑病的早期诊断有较大价值。The brain stem auditory evoked potential (BAEP ) and somatosensory evoked poten- tials (SEP) were studied on 30 patients with cor pulmonale with chronic respiratory insufficiency , 20 patients with pnenuonia and 30 healthy subjects as. control ,of the same age,at the same time. The re- sults were as follows : the abnormal ratios of BAEP and SEP for the group of cor pulmonale were 80% and 83% ,respectively ,whil. those for the group of pneumonia were 20% and 20% there. was signifi- ant statistical difference ( P < 0. 01 ) . For the cor pulmonale but not the Pneumonia. evoked potential was thought tobe sensitive physioloeical indices to brain dysfunction with respiratory failure lt may be valuable for early dignosis of pulmonary encephalopathy.
