目的探讨胎膜早破患者妊娠分娩结局与引产时限的关系。方法 86例足月妊娠胎膜早破患者,随机分为观察组和对照组,每组43例。观察组于胎膜早破后24 h引产,对照组于胎膜早破后12 h引产,比较两组阴道分娩率、自然临产率、用药前宫颈成熟度改善情况及母婴结局。结果观察组阴道分娩率为90.7%,剖宫产率为9.3%,对照组阴道分娩率为69.8%,剖宫产率为30.2%,观察组患者剖宫产率明显低于对照组,阴道分娩率明显高于对照组,差异有统计学意义(P<0.05)。两组患者宫颈改善情况比较差异有统计学意义(P<0.05)。观察组与对照组在产褥感染、新生儿窘迫发生率及新生儿窒息方面比较差异无统计学意义(P>0.05)。结论足月胎膜早破具备引导分娩条件者应期待至24 h后进行引产,可以有效地提高阴道分娩率,降低剖宫产率。
Objective To explore the relationship between the outcome of pregnancy and childbirth and the time of induction of labor in patients with premature rupture of membranes. Methods 86 cases of premature rupture of membranes in term pregnancy were randomly divided into observation group and control group, 43 cases in each group. The observation group induced labor 24 hours after premature rupture of membranes and the control group induced labor 12 hours after premature rupture of membranes. The vaginal delivery rate, spontaneous labor rate, improvement of cervical maturity before treatment and maternal-infant outcome were compared between two groups. Results The rate of vaginal delivery was 90.7% in the observation group, 9.3% in the cesarean section, 69.8% in the control group and 30.2% in the control group. The cesarean section rate in the observation group was significantly lower than that in the control group, vaginal delivery The rate was significantly higher than the control group, the difference was statistically significant (P <0.05). There was significant difference between the two groups in cervical improvement (P <0.05). The observation group and control group in the puerperal infection, the incidence of neonatal distress and neonatal asphyxia no significant difference (P> 0.05). Conclusions Full-term premature rupture of membranes with guidance of labor conditions should be expected to 24 hours after induction of labor, can effectively improve the vaginal delivery rate and reduce the rate of cesarean section.
