新生儿听力筛查影响因素分析探讨

The research on the hearing screening of the neonatus

目的探讨新生儿听力筛查有效模式,为早期诊断和干预提供合理的措施。方法采用丹麦MADSEN公司生产的筛查型耳声发射仪,对14400例新生儿进行听力测试,初次筛查异常者42d进行复筛,仍异常者测试听性脑干诱发电位确诊。结果初次筛查通过12620例,通过率为87.64%,42d复筛通过1762例,累计通过率99.88%。3个月复查累计通过率99.96%,未通过发生率0.04%。结论新生儿听力筛查有助于及早发现听力障碍患儿,并进行及时有效的干预,但日龄长短等原因会导致假阳性存在。

Objective To investigate an effective newborn hearing screening protocol for the early diagnosis and intervention of newborn hearing loss.Methods 14400 newborn hearing screening was performed based on transient evoked otoacoustic emission（TEOAE） with screening Echo-Screen（MEDSEN,Denmark）.Neonates with a refer at the first screening were retested,and those with a refer at the retest were referred to auditory brainstem response（ABR）.Results 12620 cases neonates（87.64%） passed the test for the first time and 1762 cases（total 99.88%） passed the second test.Among the subjects,6 cases（0.04%） were diagnosed as hearing loss at different degrees based on the ABR test.Conclusion Neonatal hearing screening is helpful for finding neonates with hearing impairment as early aspossible and providing the corresponding intervention.TEOAE is found to be a prefered hearing screening method in neonates because of its shortcut,non-invasiveness and accuracy.
