目的:了解新生儿先天性听力障碍发病率,探讨新生儿听力筛查的影响因素及有效的听力健康管理。方法:正常新生儿生后48h利用耳声发射进行初筛,未通过者42天后复筛;高危儿生后42天初筛,未通过者1个月后复筛;正常新生儿及高危儿两次均未通过者,进行脑干听力诱发电位测试明确诊断。结果:正常新生儿听力初筛率99.27%,复筛率98.26%;高危儿初筛率98.25%,复筛率90.47%。正常新生儿听力筛查初筛阳性率9.79%,复筛阳性率6.24;高危儿听力初筛阳性率18.84%,复筛阳性率15.29%。24822例进行听力筛查的新生儿中听力障碍发病率2.78%,干预率62.00%。结论:新生儿听力筛查、诊断和干预是一个系统工程,早发现、早干预可降低因聋致残。重点随访高危儿、定期追踪、有效的管理可提高复筛率与干预率。但应注意听力筛查的假阴性及局限性。
Objective: To understand the incidence of congenital hearing disorders in neonates, to explore the influencing factors of neonatal hearing screening and effective management of hearing health. Methods: Normal neonates were initially screened by otoacoustic emission 48h after birth, and those who failed to pass the test were resumed after 42 days. The high-risk babies were screened at 42 days after birth and those who failed the screening were screened one month later. The normal newborns and high-risk babies Were not passed, brainstem auditory evoked potentials test a clear diagnosis. Results: The normal newborn hearing screening rate of 99.27%, the rate of 98.26% screening; high risk screening rate of 98.25%, 90.47% screening rate. The positive rate of normal neonatal hearing screening was 9.79%, and the positive rate of double screening was 6.24. The positive rate of hearing screening of high-risk children was 18.84% and the positive rate of second screening was 15.29%. In 24822 newborns with hearing screening, the prevalence of hearing impairment was 2.78% and the intervention rate was 62.00%. Conclusion: Newborn hearing screening, diagnosis and intervention are a systematic project. Early detection and early intervention can reduce deafness and disability. Focus on high-risk children follow-up, regular follow-up, effective management can improve the rate of screening and intervention rate. But should pay attention to false negative hearing screening and limitations.
