摘要
为了探讨育龄妇女妊娠期脑干听觉传导路和视觉传导路的改变，观察其脑干听觉诱发电位（BAEP）及脑干视觉诱发电位（VEP-P）的变化。方法 选择最近3年来在本院做孕前检查、产前检查并在本院分娩的生育期妇女398例，在孕前、妊娠早期、妊娠晚期分别为其作3次BAEP检查和VEP-P检查。并将3次检查的结果两两对比，作配对样本均数t检验对比分析。结果 妊娠晚期的BAEP检查Ⅰ波、Ⅲ波、Ⅴ波，VEP-P检查P100各波潜伏时均值都延迟，而其他2次检查各波潜伏时均值都正常。前后3次检查的各潜伏时对比：孕前和妊娠早期对比差异无统计学意义（P＞0.05），妊娠晚期和孕前对比、妊娠晚期和妊娠早期对比差异均有统计学意义（P＜0.05）。结论 妊娠晚期，生育期妇女的BAEP的Ⅰ波、Ⅲ波、Ⅴ波潜伏时延迟，VEP-P检查P100潜伏时延迟，脑干听觉传导路和视觉传导路的传导减慢。
To investigate the change of brainstem auditory pathway and visual pathway during pregnancy in women of childbearing age,and observe the changes of brainstem auditory evoked potentials(BAEP)and brainstem visual evoked potentials(VEP-P).Methods 398 women of reproductive age who did pre-pregnancy physical examination,prenatal examination,and childbirth in our hospital during the last 3 years were selected.BAEP and VEP-P examinations were performed before pregnancy,in early pregnancy,and in late pregnancy respectively.And the results of three tests were compared with each other by the paired sample mean t test.Results In the third trimester of pregnancy,the mean values of latent time of I wave,III wave,and V wave of BAEP and P100 of VEP-P were all delayed,while those at the other two time points were normal;there were no statistically significant differences between pre-pregnancy and early pregnancy(P>0.05),but there were statistically significant differences between late pregnancy and pre-pregnancy,late pregnancy and early pregnancy(P<0.05).Conclusions In the third trimester of pregnancy,the mean values of latent time of I wave,III wave,and V wave of BAEP and P100 of VEP-P in the pregnant women are all delayed,and the conduction of auditory and visual pathways in brainstem slow down.
