为探讨脑干听觉诱发电位（ＢＡＥＰ）对新生儿缺氧缺血性脑病（ＨＩＥ）预后的判断价值，采用诱发电位仪检测５９例正常足月新生儿和５６例ＨＩＥ患儿在１２０ｄｂｐｅＳＰＬ纯音刺激下的ＢＡＥＰ。结果：ＨＩＥ组Ⅰ、Ⅲ、Ⅴ波波幅均显著低于正常组；除Ⅰ波潜伏期显著延长外，Ⅲ、Ⅴ波潜伏期及ⅠⅢ、ⅢⅤ、ⅠⅤ峰间期与正常组无显著性差异，但少数患者潜伏期、峰间期、Ⅴ／Ⅰ比值异常。对１０例临床、ＣＴ和ＢＡＥＰ异常均相符的患儿随访一年，全部有后遗症。说明ＢＡＥＰ波幅、潜伏期对ＨＩＥ的诊断、预后判断和疗效观察均有重要意义
In order to explore the value of brainstem auditory evoked potential (BAEP) in predicting the prognosis of neonatal hypoxic-ischemic encephalopathy (HIE), 59 normal full-term neonates and 56 HIE infants were induced by 120 dbpeSPL pure tone stimulation BAEP. Results: The amplitude of Ⅰ, Ⅲ and Ⅴ wave in HIE group were significantly lower than those in normal group. Except for the significant prolongation of Ⅰ wave latency, the latency of Ⅲ and Ⅴ wave and the peak of Ⅰ Ⅲ, Ⅲ V and Ⅰ V were not significantly different from those of normal group Significant differences, but a small number of patients in the incubation period, the peak period, â ... ¢ 1 ratio abnormalities. 10 cases of clinical, CT and BAEP abnormalities were followed up for one year, all with sequelae. Explain BAEP amplitude, latency of the diagnosis of HIE, prognosis and efficacy of observation are of great significance
