摘要:

目的:探讨新产程管理标准下第二产程时长对实施无痛分娩母儿结局的影响。方法:选择2016年6月至2017年6月在东南大学附属中大医院产科足月实施无痛经阴道分娩的单胎初产妇进行研究。将产妇按第二产程时长不同进行分组,即第二产程时长≥2 h的设为观察组(A组),同时根据第二产程时长延长的程度将A组细分为A1组(第二产程时长≥2 h且<3 h)、A2组(第二产程时长≥3 h);第二产程时长<2 h的设为对照组(B组)。对两组母儿结局的临床资料进行比较。结果:共有623例孕妇纳入研究,其中A组273例(A1组148例,A2组125例),B组350例。A1组、A2组和对照组两两比较产钳助产率、会阴侧切率、产后出血率、新生儿窒息率、新生儿住院率等差异均无统计学意义(P>0.05)。结论:新产程管理中无痛分娩初产妇第二产程时长的延长并未增加对母儿不良结局的影响。

Objective:To study the effect of the second stage labor time in the new labor management on outcomes of fetus and primiparas under painless labor. Methods:From June 2016 to June 2017 in Department of Obstetrics, Zhongda Hospital, Southeast University southeast university, primiparas with full-term pregnancy and single embryo under painless vaginal delivery were selected for the study. According to the second stage labor time, all primiparas were divided into three groups, namely group A1(2 h ≤ t<3 h), group A2(t ≥ 3 h) and group B(t<2 h). The clinical data of three groups of fetus and primiparas were compared. Results:A total of 623 cases of primiparas were included in the study, with 148 cases in group A1, 125 cases in group A2, and 350 cases in group B. There were no statistically significant differences in forceps midwifery rate, episiotomy rate, rate of postpartum hemorrhage, neonatal asphyxia rate and neonatal hospitalization rate among the three groups(all P>0.05). Conclusion:Extension of the second stage labor time of the new labor management does not increase influence on bad outcomes of fetus and primiparas under painless labor.
