2358例新生儿听力筛查结果分析

An analysis on the results of hearing screening in 2358 neonates

目的了解耳声发射在新生儿听力筛查中的应用及筛查通过的情况，并探讨其影响因素。方法应用瞬间诱发性耳声发射（TEOAE）对2011年1月至10月期间在我院住院分娩的新生儿进行耳声发射听力筛查，连续2次筛查不通过者42d后复筛，复筛未通过者，3个月内做听力学诊断性检查项目以确诊，并做好资料登记。结果初筛率90．62％，初筛通过率88．08％；复筛率97．86％，复查通过率88．36％；听力障碍检出率1．70％。孕周是耳声发射听力初筛通过率的危险因素[B=1．524，Exp（B）=4．589，P〈0．05]，出生体重是耳声发射听力初筛通过率的保护因素[B=-0．647，Exp（，B）=0．523，P〈0．05]。高危儿是耳声发射听力复筛通过率的危险因素[B=0．374，Exp（B）=1．453，P〈0．05]。结论TEOAE可作为婴儿听力筛查测试和监测的重要方法，通过筛查能早期发现和早期干预婴儿听力障碍。高危情况对筛查通过率有影响。

Objective To investigate otoacoustic emission in newborn hearing screening and the pass rate of screening, and to explore the related influencing factors, Methods Transient evoked otoacoustic emission （ TEOAE ） was used for hearing screening in neonates who were born during the period of January 2011 to October 2011. The neonates who did not pass the two consecutive screening would do TEOAE on 42 days afte birth and those who still failed in the third screening would take audiologic diagnostic test. The data were noted. Results The primary screening rate was 90.62% and the pass rate of the primary screening was 88.08% the secondary screening rate was 97.86% and the pass rate of secondary screening was 88.36%. The detection rate of dysaudia was 1.70 %o. Gestational age was the risk factor of otoacoustic emission for primary hearing screening [B = 1.524, Exp （ B ） = 4.589, and P〈 0.05], while birth weight was the protective factor [B = - 0.647, Exp （ B ） = 0.523, and P 〈 0.05]. High risk infants was the risk factor of secondary screening [B = 0.374, Exp （ B ） = 1.453, and P 〈 0.05]. Conclusions TEOAE can be used as an important procedure for infant hearing screening and monitoring. Infant dysaudia can be found and intervented earlier by screening. High risk factors have an effect on he pass rate of screening.
