摘要
目的观察新产程标准下初产妇产后早期盆底肌肌电值及产科影响因素,为临床预防和治疗提供理论依据。方法收集229例无剖宫产指征初产妇一般资料、产科相关资料及产后6~8周行盆底表面肌电筛查的肌电检测数据,对相关数据进行单因素及Logistic回归分析。结果新产程标准下经阴道分娩初产妇产后早期Ⅰ类肌纤维持续收缩平均肌电值、Ⅱ类肌纤维快速收缩最大肌电值、耐力测试平均肌电值普遍下降,其异常率分别是84.7%、70.3%、83.0%。Logistic回归分析表明器械助产(OR=6.541,P=0.002)、第二产程时间≥2h(OR=1.732,P=0.010)是影响阴道分娩产妇盆底肌肌电异常的独立危险因素。结论新产程标准下经阴道分娩初产妇产后早期盆底肌肌电值普遍异常,受器械助产、第二产程时间≥2h影响。
Objective To observe the early postpartum electromyographic （EMG） value of pelvic floor muscle and its ob- stetrical influencing factors for prirnipara under new labor criteria. Method Collect the general information, obstetrical in- formation and EMG detection data from EMG screening on surface of pelvic floor. Make single factor analysis and Logistic regression analysis. Result The average EMG value on continuous contractions of type I muscle fiber, max EMG value on rapid contraction of type Ⅱ muscle fiber and average EMG value on endurance test all reduce. The abnormal rates are 84. 7 %, 70. 3 %and 83 %. Logistic regression analysis shows that instrument--associated delivery （OR= 6. 541, P= 0, 002） and time of the second stage of labor≥2 h （OR = 1.7a2, P= 0. 010） are independent risk factors of EMG abnormality on pel- vic floor muscle for vaginal delivery puerperants. Conclusion There is a general early postpartum EMG abnormality on pel- vic floor muscle for vaginal delivery puerperants under new labor criteria, which is affected by instrument--associated deliv- ery and time of the second stage of labor≥2 h.
