摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗观察孕妇在第二产程低流量吸氧对胎儿脐动脉血pH值以及妊娠结局的影响。
〖HTH〗方法〖HTSS〗〖KG*2〗将1 100例初产妇随机分为观察组和对照组各550例,观察组在宫口开全时给予鼻导管持续低流量吸氧(2 L/ min),对照组给予鼻导管空气吸入,胎儿娩出后即刻检测脐动脉血pH值,并统计妊娠结局相关指标。
〖HTH〗结果〖HTSS〗〖KG*2〗观察组胎儿窘迫率、新生儿窒息率、阴道助产率、剖宫产率、产后出血率、胎儿脐动脉血pH值与对照组差异均无统计学意义(P>005)。
〖HTH〗结论〖HTSS〗〖KG*2〗孕妇在第二产程低流量吸氧不影响胎儿脐动脉血pH值,且对妊娠结局没有影响。

Abstract: [Abstract] Objective〖HTSS〗〓To assess the effect of the use of low flow  maternal oxygen during the second stage of labor on the umbilical cord artery pH and pregnancy outcome. 
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓In this randomized controlled trial(RCT), 1 100 women undergoing the second stage of labor who had no complications were randomly allocated to receive either oxygen at a flow rate of  2 L/min or sham at a flow rate of  0 L/min by the nasal cannula. Management of labor were similar in the two groups. Primary outcome was umbilical cord artery pH, and other pregnancy outcomes were recorded.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓There were no significant differences between the two groups in the fetal distress rate, neonatal asphyxia rate, instrumental vaginal delivery rate and cesarean section rate.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The use of 2 L/min maternal oxygen during the second stage of labor could not affect the umbilical cord artery pH,and could not improve the pregnancy outcome.
