【摘要】:目的:探讨不同年龄正常听力新生儿和婴幼儿听性脑干反应(ABR)波潜伏期的特点及变化规律,为准确评估新生儿及婴幼儿的听力情况提供参考。方法:选取2010年3月~2013年3月间在该院进行听力检查且结果正常的新生儿和婴幼儿153名(306耳),将其按不同年龄段分组进行ABR测试,同时选取18~25岁的正常青年人19名(38耳)为对照组,对比组间各波潜伏期和波间期的变化情况。结果:ABR波Ⅰ、Ⅲ、Ⅴ潜伏期时间随着新生儿和婴幼儿月龄的增大而逐渐变短,其中波Ⅰ潜伏时间1~7日组、30~59日组、2~4个月组明显长于对照组;波Ⅲ潜伏时间1~7日组、30~59日组、2~4个月组、5~7个月组明显长于对照组;波Ⅴ潜伏时间1~7日组、30~59日组、2~4个月组、5~7个月组、8~10个月组、11~13个月组、14~16个月组明显长于对照组;以上差异均有统计学意义(P0.05)。ABRⅠ~Ⅲ、Ⅰ~Ⅴ波间期分别于8~10个月、17~19个月起和对照组之间差异无统计学意义(P0.05),Ⅲ~Ⅴ波间期至20~24个月时和对照组比较差异有统计学意义(P0.05)。结论:新生儿和婴幼儿ABR检测结果应当结合不同月龄和各波潜伏期、波间期等指标进行综合分析,不能直接参照正常成人标准。
