摘要
目的 探讨非听力因素对新生儿听性行为反应的影响 ,为提高新生儿行为测听法的灵敏度和特异性提供参考。方法 10 2名正常新生儿按分娩方式分为顺产组 4 2例 ,剖宫产组 6 0例 ,经瞬态诱发性耳声发射 (transientevokedotoacousticemission ,TEOAE)测试 ;后声场给声 ,刺激声分别为 3kHz纯音、高频窄带噪声及白噪声 ,声强为 90dBSPL分析恒定强度下眼睑反应、头颈反应、面部反应、肢体反应的引出率。结果 10 2名新生儿均可引出良好的TEOAE波形。眼睑反应的引出率两组无差异 ,高频窄带噪声的头部反应引出率顺产组高于剖宫产组 (P <0 .0 5) ,3kHz纯音和白噪声的面部反应引出率顺产组明显高于剖宫产组 (P<0 .0 1) ,三种刺激声的肢体听反应引出率顺产组均高于剖宫产组 (P <0 .0 1)。结论 除听力因素外 ,其他可能导致新生儿宫内缺氧的因素有可能对新生儿听性行为反应产生影响 。
Objective To study the effect of non hearing factors on auditory behaviors in newborns. Methods 102 newborns (42 in the normal labor group and 60 in the cesarean section group) were studied. Behavioral audiometry was carried out in the sound field in the newborns who passed the TEOAE screening. Irritant tones included pure tone (3kHz), high pass narrowband noise and white noise. The initiation rates of four behaviors were the rates of auropalpebral responses, head responses, facial responses and body responeses. Results TEOAE wave forms were initiated in all the newborns. The initiation rate of auropalpebral responses had no significant difference between the two groups. The head response rate evoked by high pass narrowband noise was higher in the normal labor group than that in the cesarean section group (P< 0.05 ). The facial response rate evoked by 3kHz pure tone and white noise in the normal labor group was higher than that in the cesarean section group. The body response rates of three acoustic stimuli in the normal labor group were higher than that in the cesarean section group (P< 0.01 ). Conclusion The factors of fetal anoxia might affect the auditory behaviors of newborns as well as auditory factors. Auropalpebral response is an index and the most sensitive one in newborn behaviors.
