摘要 目的 评价应用视觉、体表感觉诱发电位作为诊断肺性脑病的辅助定量指标。方法  5 0例肺源性心脏病患者 ,其中肺性脑病 11例 ,非肺性脑病 39例和 2 0例正常者进行了视觉、体表感觉诱发电位的检测。结果 体表感觉诱发电位除P60 潜伏期肺脑组与Ⅱ型呼衰组有显著性差异外 ,其余各波潜伏期肺脑组与Ⅱ型呼衰组组间差异无显著性。而同时视觉诱发电位P10 0 潜伏期肺脑组同非肺脑组及正常组相比较差异皆有显著性 (P <0 0 5 )。结论 视觉诱发电位P10 0 和体表感觉诱发电位P60 潜伏期的延长作为一项辅助定量指标 。 Objective To evalue application of visual,somatosensory evoked potentials as auxiliary quantitative parameter in the diagnosis of pulmonary encephalopathy.Methods 39 nonencephalophathic and 11 encephalopathic patients with cor pulmonale and 20 controls were assessed simutaneously with VEP and SEP.Results SEP:The latency of P 60 was found to be significantly increased in the encephalopathic patients compared with type Ⅱ respiratory failure,there were no difference in other latency of wave.VEP:The latency of P 100 in encephalopathy group differs greatly from those in nonencephalopathy group and normal subjects( P <0 05).Conclusion The delays in the P 100 latency (VEPs)and P 60 latency (SEPs)as auxiliary quantitative marker may help to detect early and predict state of an illness.
