摘　　要：目的:探究腰-硬联合麻醉(CSEA)用于阴道分娩对产后盆底肌电生理功能及产程的影响。方法:选择2019年1月至2020年12月于佛山市南海区人民医院足月阴道分娩的初产妇100例,年龄21~30岁,根据是否采用CSEA镇痛分为CSEA组和对照组,每组50例。产后3个月检查盆底肌电生理功能,分析两组产妇盆底肌肌力分级情况、正常电生理功能情况及产程时间的差异性。结果:产后3个月,两组产妇Ⅰ类肌纤维、Ⅱ类肌纤维盆底肌力分级相比,差异无统计学意义(P>0.05);两组正常盆底动态压力、正常Ⅰ类肌纤维盆底肌力、正常Ⅱ类肌纤维盆底肌力、正常Ⅰ类肌纤维盆底肌疲劳、正常Ⅱ类肌纤维盆底肌疲劳等比较,差异无统计学意义(P>0.05)。CSEA组第一产程时间、第二产程时间、总产程等均低于对照组,差异有统计学意义(P<0.05)。结论:阴道分娩中实施腰-硬联合麻醉,能够缩短产妇分娩的时间,且不会对产妇的盆底肌电生理功能造成影响。Objective:To explore the effects of combined spinal-epidural analgesia(CSEA)during labor on postpartum electrophysiological function of maternal pelvic floor muscle and labor process.Methods:A total of 100 primiparas,aged 21-30 years,who delivered vaginally in Foshan Nanhai District People's Hospital from January 2019 to December 2020,were divided into CSEA group and control group according to whether CSEA was used for analgesia,with 50 cases in each group.The electrophysiological function of pelvic floor muscle was examined at 3 months after delivery,and the differences of pelvic floor muscle strength grade,normal electrophysiological function and labor process time between the two groups were analyzed.Results:Electrophysiology analysis at 3 month after delivery showed no significant differences between the two groups in muscle strength scores for type Ⅰ or type Ⅱ fibers(P>0.05).There was no significant difference between the two groups in normal pelvic floor dynamic pressure,normal type Ⅰ muscle fiber pelvic floor muscle strength,normal type Ⅱ muscle fiber pelvic floor muscle strength,normal type Ⅰ muscle fiber pelvic floor muscle fatigue,normal type Ⅱ muscle fiber pelvic floor muscle fatigue(P>0.05).The time of the first stage of labor,the second stage of labor and the total stage of labor in the CSEA group was shorter than that in the control group(P<0.05).Conclusion:Combined spinal-epidural anesthesia in vaginal delivery can shorten the time of delivery,and will not affect the electrophysiological function of maternal pelvic floor muscle.
