基层医院新生儿听力筛查方法与评定标准的建立

Establishment of method and evaluated criteria for newborn hearing screening in the gross-roots hospital

目的 :探讨新生儿听力筛查的最佳方法与相关标准。方法 :应用Cepella耳声发射仪对 12 77例(2 5 5 4耳 )新生儿作瞬态诱发耳声发射 (TEOAE)测试。以 4个频带中 3个频带信噪比≥ 3dB为通过标准。结果 :通过率为 89.4%,测试时间以产后 2d以上为佳。结论 :TEOAE是新生儿听力筛查的首选方法 ,频带信噪比≥ 3dB为最适当的筛查标准。

Objective:To study a optimal method and pass criterion for newborn hearing screening.Method: Transient evoked otoacoustic emissions(TEOAE) was used for hearing screening in 1 277 (2 554 ears) newborns.The pass criterion was definned as signal-noise-ratio(SNR) ≥3 dB in 3 of 4 frequency bands.Result: Pass rates were 89.37 %.The best tested time at 2～4 days after birth.Conclusion: TEOAE may be an ideal method for newborn hearing screening, SNR≥3 dB for freqnency bands was the appropriate pass criteria.
