5%碳酸氢钠联合缩宫素静脉滴注在分娩中的应用

目的探讨5%碳酸氢钠静脉滴注在产妇分娩过程中宫缩乏力伴极度疲劳应用的疗效。方法将2009年7月～2010年3月在我院经阴道分娩出现宫缩乏力伴极度疲劳的初产妇300例,随机分为观察组和对照组,各150例。观察组在静滴缩宫素后,在第一产程中测定产妇血二氧化碳结合力(CO2CP)并给予5%碳酸氢钠200 mL快速静滴;对照组仅给予缩宫素静脉滴注,观察两组宫缩情况、血CO2CP值、产程进展、产后出血及新生儿窒息率。结果观察组显效率及总有效率明显优于对照组(P<0.05);观察组产妇血CO2CP明显高于对照组,产程时间、产后出血率及新生儿窒息率均低于对照组(P<0.05),且有效提高阴道分娩率。结论在产妇极度疲劳伴宫缩乏力情况下应用碳酸氢钠联合缩宫素,能有效改善产妇酸中毒情况并加速产程进展,减少产后出血。

The application of 5% Sodium Bicarbonate co-infusion of oxytocin in the delivery

Objective To explore the effect of 5% Sodium Bicarbonate infusion during delivery in maternal uterine inertia associated with the application of extreme fatigue.Methods 300 primipara patients appeared vaginal delivery with uterine inertia and extreme fatigue from July 2009 to March 2010 in our hospital were randomly divided into two groups,observation group and control group,each had 150 cases.In the observation group,patients were given 5% Sodium Bicarbonate 200 mL by rapid intravenous infusion after intravenous infusion of oxytocin in the first stage to determine maternal blood CO2CP;the control group were given intravenous infusion of oxytocin,the contraction,the blood CO2CP value,the progress of labor,postpartum hemorrhage and neonatal asphyxia were observed.Results The efficiency rate and total efficiency rate in the observation group were better than those of the control group(P < 0.05);in observation group,the maternal blood CO2CP was higher than that of the control group,the time,labor,postpartum hemorrhage and neonatal asphyxia were lower than those of the control group(P < 0.05),and effectively improved the rate of vaginal delivery.Conclusion In the extreme fatigue associated with maternal uterine inertia case of sodium bicarbonate co-oxytocin,can effectively improve the situation of maternal acidosis and accelerate the progress of labor and reduce postpartum hemorrhage.
