目的:通过对产程中的镇痛效果及对母婴结局影响的观察,探讨分娩镇痛的必要性。方法:选择接受分娩镇痛的100例产妇为试验组,未接受分娩镇痛的100例为对照组。采用视觉模拟疼痛评分(VAS)评价两组活跃期和第二产程的疼痛感受及两组的产程、分娩方式、新生儿窒息、产后出血、尿潴留的发生情况。结果:试验组活跃期和第二产程的VAS与对照组相比明显低,差异有统计学意义(P<0.05);试验组与对照组相比无产程延长、新生儿窒息等(P>0.05);产后出血、产后尿潴留的发生率差异无统计学意义(P>0.05);试验组的顺产率提高,剖宫产率下降,两组相比差异均有统计学意义(P<0.05)。结论:分娩镇痛能有效减轻分娩疼痛,安全有效,对产程、母婴结局无不良影响,且能有效地降低剖宫产率。 OBJECTIVE: To explore the necessity of analgesia during labor by observing the analgesic effects of labor and the effects on maternal and infant outcomes. Methods: 100 maternal women receiving labor analgesia were selected as the experimental group, while 100 women who did not receive analgesia during labor were selected as the control group. Visual acuity pain score (VAS) was used to evaluate the pain perception in both active and second stage of labor and the incidence of labor, mode of delivery, neonatal asphyxia, postpartum hemorrhage and urinary retention in both groups. Results: Compared with the control group, the VAS in the active phase and the second stage of labor in the experimental group was significantly lower than that in the control group (P <0.05). Compared with the control group, the VAS in the experimental group was prolonged without labor and neonatal asphyxia (P> 0.05 ). There was no significant difference in the incidence of postpartum hemorrhage and postpartum urinary retention between the two groups (P> 0.05). The incidence of postpartum hemorrhage and postpartum urinary retention was not significantly different (P> 0.05) . Conclusion: Labor analgesia can effectively relieve the pain of childbirth, is safe and effective, has no adverse effect on labor process and maternal and infant outcomes, and can effectively reduce the cesarean section rate.
