剖宫产与顺产新生儿脐血血气分析结果的比较

Comparison of Cord Blood Gas of Newborns between Cesarean Section and Natural Delivery

目的探讨两种分娩方式下新生儿脐血血气分析结果的差异。方法 2010年1—10月分娩的252例无妊娠期合并症及并发症新生儿,胎儿超声影像检查正常,根据分娩方式的不同分为剖宫产组和顺产组,对其所测血气分析结果进行比较。结果剖宫产新生儿脐血的细胞外CO2分压、pH值、细胞外碱剩余、全血碱剩余、HCO3-浓度、H2CO3浓度、CO2总量、氧含量均要高于顺产新生儿,顺产新生儿脐血的血红蛋白浓度、红细胞比容要高于剖宫产新生儿,而在CO2分压、O2分压、血氧饱和度方面的差异无统计学意义。结论剖宫产和顺产新生儿的脐血血气参数存在差异,有必要分别制定不同分娩方式下血气参数的异常界定值。

Objective To explore the differences of cord blood gas between cesarean section and natural delivery.Methods From January to October 2010,252 newborns with normal fetal ultrasound examination and without complications were divided into cesarean section group and natural delivery group according to their delivery mode.Results p（CO2） in the extracellular,pH value,extracellular bases excess,blood bases excess,HCO3-concentration and the concentration of H2CO3,total CO2 and oxygen content in the cesarean group were higher than those in the natural delivery group,while the concentration of hemoglobin and HCT were lower.However,the indexes of p（CO2）,p（CO2）,and SO2 did not show statistical significance.Conclusion There are differences between of fetal cord blood gas between cesarean section and natural delivery,thus it is necessary to develop boundary points separately according to the mode of delivery.
