【摘要】：目的:探討不同年齡正常聽(tīng)力新生兒和嬰幼兒聽(tīng)性腦干反應(yīng)(ABR)波潛伏期的特點(diǎn)及變化規(guī)律,為準(zhǔn)確評(píng)估新生兒及嬰幼兒的聽(tīng)力情況提供參考。方法:選取2010年3月~2013年3月間在該院進(jìn)行聽(tīng)力檢查且結(jié)果正常的新生兒和嬰幼兒153名(306耳),將其按不同年齡段分組進(jìn)行ABR測(cè)試,同時(shí)選取18~25歲的正常青年人19名(38耳)為對(duì)照組,對(duì)比組間各波潛伏期和波間期的變化情況。結(jié)果:ABR波Ⅰ、Ⅲ、Ⅴ潛伏期時(shí)間隨著新生兒和嬰幼兒月齡的增大而逐漸變短,其中波Ⅰ潛伏時(shí)間1~7日組、30~59日組、2~4個(gè)月組明顯長(zhǎng)于對(duì)照組;波Ⅲ潛伏時(shí)間1~7日組、30~59日組、2~4個(gè)月組、5~7個(gè)月組明顯長(zhǎng)于對(duì)照組;波Ⅴ潛伏時(shí)間1~7日組、30~59日組、2~4個(gè)月組、5~7個(gè)月組、8~10個(gè)月組、11~13個(gè)月組、14~16個(gè)月組明顯長(zhǎng)于對(duì)照組;以上差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。ABRⅠ~Ⅲ、Ⅰ~Ⅴ波間期分別于8~10個(gè)月、17~19個(gè)月起和對(duì)照組之間差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05),Ⅲ~Ⅴ波間期至20~24個(gè)月時(shí)和對(duì)照組比較差異有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:新生兒和嬰幼兒ABR檢測(cè)結(jié)果應(yīng)當(dāng)結(jié)合不同月齡和各波潛伏期、波間期等指標(biāo)進(jìn)行綜合分析,不能直接參照正常成人標(biāo)準(zhǔn)。
[Abstract]:Objective: to investigate the characteristics and changes of auditory brainstem response (ABR) wave latency in neonates and infants with normal hearing of different ages, and to provide reference for accurate evaluation of hearing status in neonates and infants. Methods: from March 2010 to March 2013, 153 neonates and infants (306 ears) with normal results were selected and divided into different age groups for ABR test. At the same time, 19 normal young people (38 ears) aged 18 years and 25 years old were selected as the control group to compare the changes of wave latency and wave interval between the two groups. Results: the latency time of ABR wave 鈪，
