目的:了解新生儿听力筛查工作的结果。方法:应用畸变产物耳声发射(DPOAE)技术对新生儿进行听力普遍筛查,未通过者在满月或产后42天用同样的方法进行复查,仍未通过者,转诊用脑干诱发电位(ABR)技术检查,并跟踪随访。结果:2006年7月～2007年11月共有新生儿1804例可供筛查,接受筛查1648例,通过1129例,初筛率91.35%,通过率68.51%。需42天内复筛者519例,实际复筛336例,通过315例,复筛率64.74%,复筛通过率93.75%。经ABR检查确诊为新生儿先天性听力障碍3例(5只耳),新生儿先天性听力障碍在本组资料中的发生率为1.82‰。结论:开展新生儿听力筛查非常必要,耳声发射技术适用于临床快速筛查新生儿听力。通过筛查可及早发现先天性听力障碍儿童,及早干预,利于婴幼儿言语-语言及心理行为的健康发育。
Purpose: To understand the outcome of neonatal hearing screening. Methods: Normal hearing screening was performed on neonates with Distortion Product Otoacoustic Emission (DPOAE) technique. Those who failed the procedure were reviewed by the same method 42 days after the full moon or postnatal period, and those who had not passed were referred for brainstem response ABR) technical inspection, and follow-up. Results: From July 2006 to November 2007, a total of 1804 newborns were screened, 1648 were screened, and 1129 were screened. The screening rate was 91.35% and the passing rate was 68.51%. In 42 days, 519 patients were screened, 336 patients were screened through 315 cases, the rate of re-screening was 64.74%, and the rate of rescreening was 93.75%. In 3 cases (5 ears) of congenital hearing impairment confirmed by ABR examination, the incidence of congenital hearing impairment in neonates was 1.82 ‰ in this group. Conclusion: Neonatal hearing screening is necessary. Otoacoustic emission technique is suitable for rapid clinical screening of neonatal hearing. Early detection of early detection of congenital hearing loss in children through early intervention is conducive to the healthy development of verbal - language and psychological behavior in infants and young children.
