目的:探讨新生儿听力普遍筛查方案中不同的初筛时间的效果。方法:选取我院2009年9月1日到2011年12月31日收治的3500例新生儿,按照随机分配的方法,将其分为A组与B组,A组为出生3日新生儿,共2200例,B组为出生30日新生儿,共1300例。分别在出生后第3d、第30d时给予畸变产物耳声发射听力筛查。1个月后复筛未通过者,复筛为阳性者,转至听力评估中心诊断。结果:经过筛查后,A组初筛合格率为82.3%,复筛合格率86.1%。B组初筛合格率94.2%,复筛通过率63.5%。两组新生儿的初筛合格率、复筛合格率、总合格率对比,存在显著性差异(P<0.05);A组转诊率为1.71%,B组转诊率为1.80%,两组对比无显著性差异(P>0.05);5例新生儿最终确诊属于听力损失。结论:针对新生儿听力普遍筛查,在出生后30d时筛查,可增加初筛合格率,减少复筛例数,节省筛查成本,值得临床推广应用。
Objective: To investigate the effects of different screening time in neonatal hearing screening program. Methods: 3500 newborns admitted to our hospital from September 1, 2009 to December 31, 2011 were randomly divided into group A and group B. Group A was born on the 3rd newborn, A total of 2200 cases, B group was born on the 30th newborn, a total of 1300 cases. Distortion otoacoustic emission hearing screening was given on the 3rd day and the 30th day after birth respectively. After 1 month failed to pass the screening, re-screening was positive, to the hearing assessment center diagnosis. Results: After screening, the pass rate of screening in group A was 82.3% and the pass rate of rescreening was 86.1%. The pass rate of screening in group B was 94.2%, the pass rate of screening was 63.5%. There was a significant difference (P <0.05) between the two groups of screening rate of newborn screening, passing rate of screening, the total pass rate (P <0.05); the referral rate was 1.71% in group A and 1.80% in group B, There was no significant difference between the two groups (P> 0.05). The final diagnosis of 5 newborns was hearing loss. Conclusion: According to the common hearing screening of newborns, screening at 30 days after birth can increase the pass rate of primary screening, reduce the number of re-screening and save the screening cost, which is worthy of clinical application.
