自控硬膜外分娩镇痛对分娩结局的影响

The impact of patient controlled epidural analgesia on the outcome of delivery

目的探讨自控硬膜外分娩镇痛(PCEA)对产妇及新生儿的影响。方法选择符合入选条件的初产妇267例,其中实施PCEA者(实验组)131例,常规措施助产者(对照组)136例。比较两组的分娩方式、产程、催产素使用情况、产后出血量、胎儿宫内窘迫发生率及新生儿Apgar评分等的差异。结果实验组活跃期及第二产程较对照组显著延长(P<0.05),催产素使用率也明显高于对照组(P<0.05)。结论PCEA用于初产妇分娩镇痛可延长产程并可能对新生儿有一定的影响,建议用于痛阈值较低的孕妇。

Objective To assess the impact of patient controlled epidural analgesia（PCEA）for labor on the primipara and the neonate. Methods 267 nulliparous parturients were enrolled in the trial. 131 parturients in PCEA group received PCEA for labor of their own accord and 136 in control group received no labor analgesia. Data were collected about delivery mode, labor stage,oxytocics useness, postpartum hemorrhage,incidence of fetal distress and APGARS of the neonate. Results The duration of active phase and the second labor stage in PCEA group was longer than control group（P〈0.05）, useness rate of oxytocics was higher than control group（P〈0.05）. Conclusion PCEA used in labor analgesia of nulliparous parturients may delay the labor progress and have some impact on the neonate.
