摘要： 目的 探讨新产程标准管理下合理选择入院时机对低危初产妇产程及分娩方式的影响。 方法 收集2017年1月至2018年12月于温州医科大学附属第一医院产科住院分娩的低危初产妇的临床资料,总计1 057例,按孕妇入院时宫口扩张情况分为两组:宫口扩张<3 cm为A组(n=913),宫口扩张≥3 cm为B组(n=144)。采用病例-对照研究方法对两组临床资料进行单因素及多因素二元Logistic回归分析,分析入院时机对初产妇产程干预、产程及剖宫产率等妊娠结局的影响。 结果 A组孕妇体质量指数(BMI)(F=5.489, P=0.019)大于B组,分娩孕周(F=6.776, P=0.009)、胎儿出生体质量(F=9.721, P=0.002)均大于B组;A组孕妇有更高的无痛分娩比率(χ2=38.145, P<0.001),产程中催产素(χ2=10.416, P<0.001)、间苯三酚使用率(χ2=6.481, P<0.001)高于B组,第一产程时间(F=51.05, P<0.001)、总产程时间(F=49.76, P<0.001)、住院日(F=40.613, P<0.001)较B组孕妇长。A组宫产率(χ2=3.929, P=0.047)、产后出血量(F=6.724, P=0.01)、胎儿窘迫率(χ2=5.085, P=0.024)高于B组。多因素回归分析提示早入院(宫口扩张<3 cm)是第一产程(OR=3.347, 95%CI=2.062~5.431)、总产程(OR=3.792, 95%CI=2.292~6.271)时间延长的独立危险因素。 结论 宫口扩张≥3 cm入院可减少不必要的医疗干预,缩短产程时间,降低剖宫产率,改善母婴妊娠结局。

Abstract: Objective To explore the effects of admission time on labor duration and delivery mode among primiparas under new partogram. Methods A retrospective analysis was conducted on the data of 1 057 primiparas during January 2017 and December 2018. The subjects were divided into group A(n=913, cervical dilatation <3 cm)and group B(n=144, cervical dilatation ≥3 cm). The effects of admission time on delivery mode and obstetric outcomes were explored using univariate and multivariate Logistic regression analyses. Results Compared with group B, group A had larger BMI(F=5.489, P=0.019), longer gestational weeks(F=6.776, P=0.009), heavier fetal weight(F=9.721, P=0.002); higher rate of painless delivery(χ2=38.145, P<0.001), higher usage rate of oxytocin(χ2=10.416, P<0.001)and phloroglucin(χ2=6.481, P<0.001); longer first labor duration(F=51.05, P<0.001), total labor duration(F=49.76, P<0.001)and hospitalization(F=40.613, P<0.001); higher rate of Cesarean section(χ2=3.929, P=0.047), higher incidence of fetal distress(χ2=5.085, P=0.024), and larger amount of postpartum bleeding(F=6.724, P=0.01). Multiple Logistic analysis revealed that early admission was independently associated with prolonged first stage of labor(OR=3.347, 95%CI=2.062-5.431)and total duration of labor(OR=3.792, 95%CI=2.292-6.271). Conclusion Admission when cervical dilatation ≥3 cm could avoid unnecessary interventions, shorten the stage of labor, reduce the high rate of Cesarean delivery and improve the pregnancy outcomes.
