【摘要】：目的:探讨新产程标准管理下硬膜外阻滞分娩镇痛产妇第二产程时长对新生儿Apgar评分及脐动脉血气分析等的影响。方法:回顾新产程标准在我院实行2年以来(2014年10月至2016年9月)第二产程持续时间≥3h的单胎、足月、头先露、无合并症初产妇且行硬膜外阻滞分娩镇痛的病例,去除死胎引产、胎儿畸形、前置胎盘、中转剖宫产病例,满足条件共91例为研究组(A组),根据第二产程持续时间长短将其分为3组:3~3.5h,共51例设为A1组;3.5~4h,共25例为A2组;≥4h,共15例为A3组。随机抽取同期在硬膜外阻滞分娩镇痛下阴道分娩且第二产程3h的符合入组条件的病例共160例作为对照组(B组)。回顾并收集4组产妇的病历资料,将A1组、A2组、A3组的新生儿Apgar评分及脐动脉血气分析结果与B组进行比较。结果:A1组新生儿低Apgar评分发生率高于B组(P0.05),脐动脉血气分析及转科治疗情况与B组相比无明显差异(P0.05)。A2组低1分钟Apgar评分(16%)、低5分钟Apgar评分(4%)发生率明显高于B组(分别为4.4%,0.6%)(P0.05);A2组脐动脉血气分析[pH 7.185±0.11,BE值(-5.81±3.1)mmol/L,乳酸(5.23±1.9)mmol/L]与B组[pH 7.275±0.08,BE值(-3.51±3.3)mmol/L,乳酸(2.95±3.1)mmol/L]相比,差异有统计学意义(P0.05),新生儿转科率高于A1组及B组;A3组低1分钟Apgar评分(46.7%)及低5分钟Apgar评分(26.7%)发生率明显高于B组及A1、A2组(P0.01);脐动脉血气分析[pH 7.135±0.08,BE值(-8.55±0.9)mmol/L,乳酸(7.85±1.5)mmol/L)]与B组及A1、A2组相比有显著差异(P0.01),新生儿转科及NICU率明显增加。结论:硬膜外阻滞分娩镇痛下第二产程3h新生儿低Apgar评分发生率升高;新生儿脐动脉血p H值下降,BE负值增大,乳酸含量增加,尤其第二产程≥3.5h后变化明显;新生儿短期不良结局发生率升高。
[Abstract]:Aim: to investigate the effect of epidural block on neonatal Apgar score and umbilical artery blood gas analysis in the second stage of labor analgesia under the standard management of new labor process. Methods: to review the cases of single fetus with duration of more than 3 hours in the second stage of labor since 2 years (from October 2014 to September 2016) in our hospital, who showed their heads first and did not have complications, and received epidural block for labor analgesia, and all the cases were performed with epidural block in the first trimester of labor in our hospital for 2 years (from October 2014 to September 2016). 91 cases of stillbirth induction, fetal malformation, placenta previa, and conversion to cesarean section were divided into three groups according to the duration of the second stage of labor: 3) 3.5 hours, 51 cases were set up as A1 group, and 91 cases were treated as study group (group A) according to the duration of the second stage of labor. There were 25 cases of A2 group and 15 cases of A3 group (鈮，
