脑干听觉诱发电位早期诊断化脓性脑膜炎听力损害的评估

EARLY DIAGNOSIS OF HEARING LOSSASSOCIATED WITH PURULENT MENINGL-TIS BY BRAINSTEM AUDITORY EVOKEDPOTENTIALS

应用脑干听觉诱发电位（ＢＡＥＰ）对４０例化脓性脑膜炎患儿进行检测，其中３３例为＜２岁幼婴。结果表明，１５例ＢＡＥＰ异常，１０例显示周围性听路损害，３例脑干中枢性听路损害，２例混合损害。１０例随访１年，３例完全恢复，１例部分恢复，６例仍异常。提示ＢＡＥＰ对早期诊断新生儿、幼婴化脓性脑膜炎的听力损害、判断性质、预后的监测具有重要临床价值。

For the early diagnosis of hearing loss,40 childrenwith purulent meningitis were detected by brainsternauditory evoked potentials。 Fifteen cases(37.5%)wereabnormal in BAEP findings。 Among them,10 casespresented impairment in peripheral auditory pathway,3cases,impairment in brainstem auditory pathway and 2cases, complex defects of both auditory pathways One-year follow-up studies showed that 3 patients recoveredcompletely,1 recovered partially,while 6 were stillabnormal。The result suggests that BAEP is valuable in theearly diagnosis of hearing loss,early medical interven-tion and prediction of the prognosis of infants with puru-lent meningitis。
