目的:探索重症监护病房(NICU)新生儿听力筛查模式,初步了解听力损失在此类人群的患病情况。方法:采用自动听性脑干反应(AABR)2阶段筛查方案,即NICU新生儿在出院或转入普通病房前以AABR进行听力初筛,未通过者出院1个月后门诊接受AABR复筛。复筛仍未通过者,3个月内转诊到我院儿童听力中心,进行全面的听力学诊断评估。结果:对2007-09-2008-08从NICU出院的824例新生儿进行了听力筛查,70例(8.5%)未通过出院前的AABR初筛,其中55例(78.6%)1个月后接受了AABR复筛,9例未通过。后者经全面的听力学诊断评估,3例确诊患不同程度的感音神经性听力损失,1例患听神经病。听力损失总患病率0.48%。结论:AABR两步法可能是NICU新生儿合适的听力筛查模式;本组新生儿听力损失患病率低于已往文献报道。
Objective: To explore neonatal hearing screening mode in intensive care unit (NICU) and to understand the prevalence of hearing loss in such population. Methods: AABR 2 stage screening scheme was adopted, that is, NICU newborns were tested with AABR before leaving hospital or general ward, and those who failed to receive AABR screening one month after discharge . Re-screening has not yet passed, within 3 months, referral to our hospital children’s hearing center, a comprehensive diagnostic assessment of hearing. Results: A total of 824 newborns discharged from the NICU during 2007-09-2008-08 underwent hearing screening. Seventy (8.5%) did not pass pre-discharge AABR screening, of which 55 (78.6%) were 1 month later AABR re-screening, 9 failed. The latter was evaluated by a comprehensive audiological diagnosis, with three patients diagnosed with sensorineural hearing loss to varying degrees and one patient with auditory neuropathy. The total prevalence of hearing loss 0.48%. Conclusion: The AABR two-step method may be suitable NICU neonatal hearing screening model; the prevalence of neonatal hearing loss in this group is lower than previously reported in the literature.
