性别和年龄对脑干诱发电位的影响研究

Effects of Sex and Age on the Brainstem Auditory Evoked Potentials(BAEP)

目的 探讨性别和年龄对脑干听觉诱发电位的影响。方法 检测 53例 ( 10 6耳 )正常人的BAEP ,用多元线性相关分析和逐步回归分析对其进行分析。结果 2 0～ 58岁期间的正常人Ⅲ波潜伏时、Ⅰ -Ⅲ及Ⅲ -Ⅴ峰间期与年龄有线性相关 ,但相关不高 ;Ⅰ、Ⅲ波潜伏时及Ⅲ -Ⅴ峰间期与性别有线性相关关系 ,其相关性亦不高 ,Ⅴ波潜伏时及Ⅰ -Ⅴ峰间期与性别有线性相关关系 ,其相关较高 ;女性各波潜伏时及峰间期均较男性短 ,其中以Ⅴ波潜伏时表现更为明显 ,比男性短 0 2ms。结论 性别和年龄是影响BAEP的两个主要生理因素。在临床应用时 ,如能排除其影响 ,诊断则更客观。

Objective To study the effects of sex and age on the Brainstem Auditory Evoked Potentials(BAEP).Methods 53 normal subjects' BAEP(106 ears) were examed.Multiple liner correlation and stepwise regression were used for statistical analysis.Results Wave Ⅲ latency and Ⅰ-Ⅲ,Ⅲ-Ⅴ interpeak latencies had correlation with age.All latencies and interpeak latencies(except Ⅰ-Ⅲ) had correlation with sex.All latencies and interpeak latencies were shorter in female than in male,for wave Ⅴ,this phenomenon was particularly obvious.Wave Ⅴ latency was about 0.2ms shorter in female than that in male.Conclusions Sex and age are major physiological factors on BAEP.If we pay colse attention to them in clinical application,the diagnosis is more objective and accurate.
