不同月龄婴幼儿听性稳态反应和听性脑干反应的相关性分析

The Correlation between Auditory Brainstem Responses and Auditory Steady State Responses of Infants as a Function of Ages

目的了解不同月龄婴幼儿听性稳态反应和听性脑干反应反应阈的相关性。方法对象为299例(497耳)1～36月龄的婴幼儿,分为1～月龄组208耳,4～月龄组81耳,7～月龄组47耳,13～月龄组53耳,19～36月龄组108耳,将各组ABR反应阈均值分别与ASSR的2、4kHz反应阈及2、4kHz反应阈的平均值进行相关性分析。结果1～月龄组ABR反应阈与ASSR的2、4kHz反应阈及2、4kHz反应阈平均值相关系数分别为0.499、0.541、0.531;4～月龄组分别为0.678、0.705、0.726;7～月龄组分别为0.792、0.717、0.777;13～月龄组分别为0.934、0.880、0.915;19～36月龄组分别为0.817、0.810、0.867。结论1～18月龄婴幼儿听性稳态反应和听性脑干反应反应阈的相关性随月龄增加而增加,12月龄以上均为高度相关。

Objective To investigate the correlation between auditory steady state responses（ASSR） and click audiotory brainstem respone（cABR） of infants as a function of different ages below 36 months. Methods 299 infants（497 ears from 1 to 36 months） were divided into 5 groups： 208 ears in group 1（1～ month old）,81 ears in group 2（4～ months old） ,47 ears in group 3 （7～ months old）, 53 ears in group 4 （13～ months old）, and 108 ears in group 5 （19～36 months old）. The correlation analysis of the thresholds of 2 kHz and 4 kHz between ABR and ASSR were conducted, respectively with SPSS. Results In group 1, the correlation coefficient at 2 kHz between ABR and ASSR was 0. 499, the correlation coefficient at 4 kHz between ABR and ASSR was 0. 541, the correlation coefficient of the means of 2 kHz and 4 kHz between ABR and ASSR was 0. 531. In group 2, these three correlation coefficients were0.678, 0.705 and 0.726, for group 3, 0.792, 0.717 and 0.777～ for group 4, 0.934, 0.880 and 0. 915, for group 5, 0. 817, 0. 810 and 0. 867. Conclusion For infants of 1～18 months old, the correlation between ABR and ASSR increases as a function of ages.
