改良新产程模式管理硬膜外麻醉无痛分娩产程对母婴结局的影响

Effect of improved new mode of labor management epidural anesthesia painless labor on maternal and infant outcomes

目的探讨应用改良新产程模式管理硬膜外麻醉无痛分娩产程对母婴结局的影响。方法选取2018年1月-2020年2月在长春市妇产医院自愿行硬膜外麻醉无痛分娩的单胎初产足月妊娠产妇220例为研究对象,随机分为观察组和对照组,每组各110例。观察组产妇应用改良新产程模式管理无痛分娩,对照组产妇应用新产程模式管理产程无痛分娩。观察两种产程管理模式管理产程对母婴结局影响。结果观察组产妇潜伏期、加速期及第二产程时间均较对照组明显缩短,差异均有统计学意义(均P<0.01)。两组产妇剖宫产率和产后出血率比较,差异无统计学意义(P>0.05)。观察组产妇阴道助产率明显低于对照组,差异有统计学意义(P<0.05)。观察组产妇产后出血量明显少于对照组,差异有统计学意义(P<0.05)。观察组新生儿脐动脉血pH值<7.2比例低于对照组,差异有统计学意义(P<0.05)。结论采用改良新产程模式管理的硬膜外麻醉无痛分娩产妇产程时限明显缩短,阴道助产率降低,产后出血量明显减少,新生儿脐动脉血pH值<7.2比例明显降低,因此改良新产程模式管理产程,可有效保证母婴安全。

Objective To explore the effect of epidural anesthesia and painless labor process on maternal and infant outcomes.Methods From January 2018 to February 2020,220 single term pregnant women who voluntarily underwent epidural anesthesia for painless delivery in Changchun Obstetrics-Gynecology Hospital were selected as study subjects and randomly divided into observation group and control group,with 110 cases in each group.The observation group applied the improved new labor process mode to manage painless labor,while the control group applied the new labor process mode to manage painless labor.To observe the effect of two labor process management modes on maternal and infant outcomes.Results The incubation period,acceleration period and second labor time of the observation group were significantly shorter than those of the control group,and the differences were statistically significant(P<0.01).The comparison of cesarean section rate and postpartum hemorrhage rate between the two groups showed no statistically significant difference(P>0.05).The rate of vaginal delivery in the observation group was significantly lower than that in the control group,and the difference was statistically significant(P<0.05).The amount of postpartum bleeding in the observation group was significantly less than that in the control group,and the difference was statistically significant(P<0.05).Observation group neonatal umbilical arterial blood pH<7.2 the proportion was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion The duration of labor was shortened,the rate of vaginal delivery was decreased,the amount of postpartum bleeding was decreased,and the proportion of umbilical artery blood pH<7.2 was significantly lower in neonates.Therefore,the improved new labor process mode can effectively ensure the safety of mother and child.
