由空气传递的声音刺激对胎儿呼吸及胎动的影响

采用回顾性研究方法考察了由空气传递的声音刺激对未足月与足月胎儿的呼吸性运动与胎动的影响.结果发现,胎儿通过呼吸运动的变化(如呼吸运动加速、减缓、停止/停顿等)及胎动来对外界刺激作出反应;而且这种反应在不同胎龄的胎儿间有显著的不同胎龄大的或足月的胎儿在有声音刺激条件下的呼吸运动变化比胎龄小的更多.

EFFECT OF AIRBORNE SOUND ON FETAL BREATHING AND MOVEMENT

The present study is a retrospective review and coding of the videotapes of 49 fetuses at different gestational age. The purpose of this study was to examine changes in fetal breathing movement over gestational age in response to airborne sound stimulation. The result showed that the changes in fetal breathing and body movements were modulated by sensory stimulation. And there were differences in changes of breathing and body movement between fetuses in different gestational age. That is, fetuses from 35 weeks to term were more sensitive to response to the airborne stimulation than fetuses from 32 weeks to 34 weeks.
