A difference between extrauterine and intrauterine maturation on BAEP has not been established, remaining a subject of controversy. The present study involved 76 children, aged between 36 and 37 weeks (conceptional age), with an extrauterine life duration of equal to or less than 2 weeks (N = 46) or more than 2 weeks (N = 30). The latencies for waves III and V, and the I-III and I-V intervals were significantly shorter for the neonates with a greater extrauterine life duration. An explanation for this finding is discussed: the head size is significantly smaller in the group with a greater extrauterine life duration. An influence of extrauterine life duration on BAEP is thus shown, but it seems to reflect the anatomical consideration and not to peripheral auditory system maturation.
宫外成熟与宫内成熟在脑干听觉诱发电位(BAEP)上的差异尚未确定,仍是一个有争议的话题。本研究纳入了76名年龄在36至37周(孕龄)之间的儿童,其宫外生存时间等于或小于2周(N = 46)或大于2周(N = 30)。宫外生存时间较长的新生儿,其波III和波V的潜伏期以及I-III和I-V间期明显更短。文中讨论了这一发现的解释:宫外生存时间较长的组中头部尺寸明显更小。因此显示了宫外生存时间对BAEP有影响,但这似乎反映了解剖学因素,而非外周听觉系统的成熟。
