目的 :探讨硬膜外阻滞用于分娩镇痛的镇痛效果及对产程的影响。方法 :选择 10 0例硬膜外镇痛分娩的初产妇作为观察组 ,将未采用任何分娩镇痛药物而进入产程的初产妇 10 0例作为对照组 ,分别观察产程、分娩方式、产后出血量和脐动脉血气。结果 :观察组镇痛后疼痛视觉模拟评分显著低于镇痛前 (P <0 0 1)。观察组脐动脉血 pH(7 32 8± 0 0 6 4)显著高于对照组 pH(7 2 6 3± 0 0 73) (P <0 0 1)。两组产程、分娩方式、产后出血量比较无显著性差异(P >0 0 5 )。结论 :硬膜外阻滞用于分娩镇痛安全有效 ,对母婴无不良影响。
Objective: To investigate the analgesic effect of epidural block for labor analgesia and the effect on labor process. Methods: One hundred and ten cases of primipara caused by epidural analgesia were selected as the observation group. One hundred cases of primiparas who did not use any analgesic drugs during labor were selected as the control group. The duration of labor, mode of delivery, amount of postpartum hemorrhage And umbilical artery blood gas. Results: Visual acuity scores of the pain group in the observation group were significantly lower than those before the analgesia (P <0.01). The umbilical artery pH (7 32 8 ± 0 0 6 4) in the observation group was significantly higher than that of the control group (7 2 6 3 ± 0 0 73) (P 0 01). There was no significant difference in labor, delivery mode and postpartum hemorrhage between the two groups (P> 0.05). Conclusion: Epidural blockade is safe and effective for labor analgesia and has no adverse effect on maternal and infant.
