目的评价可行走分娩镇痛在潜伏期应用的临床效果及对子宫收缩力和新生儿阿氏评分的影响。方法对确已临产无内科合并症初产妇共50例。随机分为二组。Ⅰ组:宫口开张1 cm左右;Ⅱ组:为正常对照组未采用分娩镇痛。观察镇痛起效时间,子宫收缩力的变化,总产程、产后出血量、分娩结局及新生儿阿氏评分。结果Ⅰ组与Ⅱ组相比总产程无差异。第一产程中Ⅰ组于Ⅱ组相比子宫收缩力显著降低,P<0.05,催产素使用率为100%。二组间产后出血、新生儿阿氏评分无显著差异。结论舒芬太尼合并低浓度的罗哌卡因应用于无痛分娩,有明显的分娩镇痛作用,不增加产后出血量,对新生儿的阿氏评分无影响。
Objective To evaluate the clinical effect of ambulatory labor analgesia applied in the incubation period and its effect on the uterine contractility and neonatal Asperger’s score. Methods do have no medical complications of primipara total of 50 cases. Randomly divided into two groups. Group Ⅰ: cervix opened about 1 cm; Ⅱ group: normal control group did not use labor analgesia. Observation of analgesic onset time, changes in uterine contractility, total labor, postpartum hemorrhage, delivery outcomes and neonatal Asperger score. Results There was no difference in total labor between Ⅰ group and Ⅱ group. In the first stage of labor, group Ⅰ had significantly lower uterine contractility compared with group Ⅱ, P <0.05, and the rate of oxytocin was 100%. Between the two groups postpartum hemorrhage, neonatal Ah’s score no significant difference. Conclusion Sufentanil combined with low concentration of ropivacaine for painless childbirth has obvious labor analgesic effect, does not increase the amount of postpartum hemorrhage, and has no effect on the neonatal Aspergillus score.
