对１９例重度窒息新生儿进行了视觉诱发电位（ＶＥＰ）测定，并与脑干听觉诱发电位（ＢＡＥＰ）进行了对比研究。重度窒息儿ＶＥＰ异常表现为：波整体或部分缺失、潜伏期延长。其中缺氧缺血性脑病（ＨＩＥ）患儿ＶＥＰ异常阳性率８７．５％，同期ＢＡＥＰ异常阳性率仅为５３．３％，说明ＶＥＰ对窒息后急性期脑损伤敏感性高，与临床诊断有较高一致性，是评定重度窒息儿急性期脑损伤的一种较好辅助检查手段。

19 cases of severe asphyxia neonatal visual evoked potentials (VEP) were measured and compared with brainstem auditory evoked potentials (BAEP) were compared. Severe asphyxia children with abnormal VEP performance: wave in whole or in part, the incubation period is prolonged. Among them, the positive rate of VEP abnormalities in children with hypoxic-ischemic encephalopathy (HIE) was 87.5%, and the positive rate of abnormal BAEP was only 53.3% in the same period, indicating that VEP was sensitive to acute brain injury after asphyxia and was associated with clinical diagnosis Higher consistency, is to assess severe acute respiratory syndrome in children with a better auxiliary examination means.
