胎儿听力产前检测42例研究

The research on fetal hearing in prenatal period

目的 减少聋哑儿的出生率 ,在超声实时观察下监测胎儿听器发育情况。方法 用木鱼声和拨浪鼓声刺激孕 2 1～ 39周的胎儿 ,观察其反应。结果 用 75 2 1± 1 76dBSPL的拨浪鼓声刺激胎儿 ,胎心及胎动变化均无显著差异 (P >0 0 5 ) ;用 87 0 1± 2 14dBSPL的木鱼声刺激胎儿 ,胎心及胎动变化均有显著性差异 (P <0 0 0 1) ,并有惊跳反应。结论 木鱼声 超声法安全、简便、敏感、快速、可靠 ,便于推广。

Objective To reduce the birthrate of fetus who would be deaf and mute and monitor the development of fetal auditory organs that was observed with ultrasonography.Method The fetuses at gestational ages from 21 to 39 weeks were stimulatated by the sound of wooden fish and rattle-drum.Results There is no significant difference in the changes of the embryocardia and quickening in the fetus who were stimulatated by rattlt-drum sound with 75.21±1.76 dB SPL.There is significant difference in the changes of the embryocardia and quickening in the fetus who were stimulatated by wooden fish sound with 87.01±2.14 dB SPL and the fetuses had jumpings.Conclusion The sound of wooden fish-ultrasonic is safe,simply,sensitive,fast,trustful.Therefore it is worth spreading.
