5180例新生儿听力筛查临床分析

Clinical analysis on 5180 newborn hearing screening cases

目的对新生儿听力筛查情况进行探讨,达到早发现、早诊断听力障碍的患儿,以便及时干预治疗。方法采用瞬态诱发耳声发射(transit evoked otoacoustic emission,TEOAE)听力筛查仪进行初筛,未通过的在生后42 d左右进行复筛,复筛未通过则转诊至上级医院进行确诊和治疗。结果听力筛查初筛率99.62%,初筛通过率96.53%;复筛率98.89%,复筛通过171例,复筛通过率96.07%;异常率0.58‰,异常发生率低于国内发生率(0.3%)。结论新生儿听力筛查十分重要和必要;TEOAE具有客观、敏感、准确、操作简便、无创等特点,是一种适用于临床的新生儿听力筛查首选方法,值得推广应用。

Objective To discuss and analyze newborn hearing screening and achieve early detection and diagnosis of newborn children with disaudia,so as to apply timely intervention and treatment.Methods Transit evoked otoacoustic emission（TEOAE） was used for initial screening,and rescreening was done 42 days after birth for those who fail the first time.Result The initial hearing screening rate was 99.62%,with a 96.53% passing rate.The rescreening rate was 98.89%,with 171 cases passed,or a passing rate of 96.07%.The abnormal rate was 0.58‰,which was lower than the national incidence rate（0.3%）.Conclusion Newborn hearing screening is very important and necessary,and being objective,sensitive,accurate,operationally easy,non-invasive,and etc.,TEOAE is the first choice for clinical newborn hearing screening,of which,extensive application should be promoted.
