硬膜外阻滞麻醉镇痛对产程的影响

为探讨硬膜外阻滞麻醉镇痛对产程的影响，将100例初产妇随机分为观察组（行硬膜外阻滞麻醉分娩）和对照组（正常分娩）各50例，观察两组产妇的总产程及第一产程时间，活跃期宫口扩张速率和胎头下降速率。结果观察组产妇的部产程及每产程时间均较对照组明显缩短；宫口扩张和胎头下降速率较对照组显著增快（均P＜0．01），表明硬膜外阻滞麻醉用于分娩镇痛的同时能明显促进产程进展。

Effect of Epidural Block Anesthesia Analgesia on Stages of Labor

In order to study the effect of epidural block anesthesia analgesia (EBAA) on stages of labor, 100 primiparae were randomly divided into observation group (delivery with EBAA) and control group (routine delivery) equally. The total stages of labor, the first stage of labor, uterine orifice expansion rate and descending rate of fetal head in the two groups were observed. The results showed that the total stages of labor and the first stage of labor in the observation group were obviously shortened as compared with those in the control group (P<0.01), while the uterine expansion rate and descending rate of fetal head in the observation group increased significantly (P<0.01). It was suggested that EBAA could promote the progress of labor.
