摘　　要：目的 分析产后盆底肌电生理评估中快肌收缩最大值及慢肌收缩平均值的影响因素。方法 选取2020年1月—2021年2月于南通大学第二附属医院及盐城市大丰人民医院行盆底肌电生理评估的产后妇女1 153例,对其住院分娩时的检查资料、住院信息及分娩记录进行回顾性分析。结果 本研究中,快肌收缩最大值正常组576例,异常组577例;慢肌收缩平均值正常组351例,异常组802例。产后盆底肌电生理评估中快肌收缩最大值正常组与异常组中分娩孕周、顺产比例、第一和第二产程时长、会阴裂伤比例、会阴侧切率及新生儿出生体重比较,差异有统计学意义(P<0.05);慢肌收缩平均值正常组与异常组中产前体重指数(BMI)、甘油三酯水平、产钳助产比例、顺产比例、第二产程时长、会阴裂伤比例及新生儿出生体重比较差异有统计学意义(P<0.05)。结论 孕期做好产前宣教,避免过期妊娠,控制胎儿体重,加强产程管理,避免产程过长及提高接产技术等,可能对减少产后盆底的损伤有一定作用。Objective To analyze the factors influencing the maximum value of fast muscle contraction and average value of slow muscle contraction in electrophysiological assessment of pelvic floor after delivery.Methods A total of 1 153 postpartum women who underwent pelvic floor electrophysiological assessment in the Second Affiliated Hospital of Nantong University and Yancheng Dafeng People′s Hospital from January 2020 to February 2021 were selected, and their hospitalization information and delivery records were retrospectively analyzed.Results Among the 1 153 subjects, 576 were in the normal maximum value of fast muscle contraction group and 577 were in the abnormal group. Furthermore, there were 351 in the normal average value of slow muscle contraction group and 802 in the abnormal group. There were statistical differences between the normal maximum value of fast muscle contraction group and the abnormal group in gestational age, the proportion of vaginal delivery, the length of the first and second stages of labor, the proportion of perineal laceration, the rate of perineal lateral resection and the newborn birth weight during postpartum pelvic floor electrophysiological evaluation(P<0.05). There were statistical differences between the normal average value of slow muscle contraction group and the abnormal group in prenatal BMI, triglyceride level, the proportion of forceps assisted delivery, the proportion of vaginal delivery, the length of second labor, the proportion of perineal laceration and newborn birth weight(P<0.05).Conclusions Prenatal education during pregnancy can avoid overdue pregnancy and control fetal weight. Strengthening the management of labor process, avoiding long labor process and improving delivery technology may play a certain role in reducing postpartum pelvic floor injury.
