分娩镇痛对经产妇产程及产后早期盆底肌力的影响

Effect of childbirth analgesia on postpartum labor and early postpartum pelvic floor muscle strength

目的:探讨硬膜外麻醉用于分娩镇痛对于经阴道分娩的经产妇的产程及产后早期盆底肌力的影响。方法:选取2019年1-7月足月并于分娩后6~8周复查的经产妇160例,根据分娩时是否进行分娩镇痛分为无痛组和有痛组。通过回顾其产程时间及应用PHENIX 2诊断系统对患者产后盆底肌力进行综合评级。评判经产妇产程及产后早期盆底肌力的情况。结果:无痛组总产程时间长于有痛组,差异有统计学意义(P<0.05);两组产后6~8周Ⅰ类慢肌纤维的肌力及Ⅱ类快肌纤维的肌力评级比较,差异无统计学意义(P>0.05);两组间盆底肌异常率比较,差异无统计学意义(P>0.05)。结论:分娩镇痛可使经产妇产程时间延长,但对产后早期盆底肌力无影响。

Objective:To investigate the effect of epidural anesthesia for labor analgesia on the delivery process and the strength of pelvic floor muscles in the early postpartum period.Methods:160 cases of full-term pregnant women from January to July in 2019 and reexamined 6~8 weeks after delivery were selected.According to whether labor analgesia is performed during labor,they were divided into the painless group and the painful group.By reviewing the labor process and using Phenix 2 diagnostic system,the pelvic floor muscle strength was comprehensively graded.We evaluated the labor process and pelvic floor muscle strength in early postpartum period.Results:The total labor duration of the painless group was longer than that of the painful group,the difference was statistically significant(P<0.05).There was no significant difference in the muscle strength of typeⅠslow muscle fiber and typeⅡfast muscle fiber between the two groups(P>0.05),and there was no significant difference in the abnormal rate of pelvic floor muscle between the two groups(P>0.05).Conclusion:Labor analgesia can prolong the duration of labor,but has no effect on pelvic floor muscle strength in the early postpartum period.
