目的评价分娩时脐动脉血气分析的意义。方法选取100例于2011年3～10月在大连市妇产医院住院的单胎足月自然分娩孕妇100例,对50例脐血流异常(S/D>2.5)足月胎儿分娩时行脐动脉血气分析,50例正常(S/D≤2.5)脐血流足月胎儿相同条件血气分析对照,两组均常规行产前胎儿电子监护,产后专人Apgar评分。结果两组中胎儿电子监护异常情况出现率无显著差异(P>0.05),血气分析各项指标有显著差异(P<0.05)。结论脐血流异常而Apgar评分正常的新生儿有窒息可能,应结合Apgar评分和脐动脉血气分析来共同评价新生儿预后。
Objective To evaluate the significance of umbilical arterial blood gas analysis during labor. Methods A total of 100 pregnant women of single birth full term spontaneous delivery hospitalized in Dalian Maternity Hospital from March to October in 2011 were enrolled in this study. Fifty pregnant women with umbilical cord blood flow abnormalities (S / D> 2.5) Arterial blood gas analysis, 50 cases of normal (S / D ≤ 2.5) umbilical blood flow analysis of fetal blood under the same conditions, the two groups were routinely prenatal fetal electronic monitoring, postpartum Apgar score. Results There was no significant difference (P> 0.05) in the incidence of fetal electronic monitoring anomalies between the two groups, with significant differences in all the parameters of blood gas analysis (P <0.05). Conclusions Neonates with abnormal umbilical blood flow and normal Apgar score have the possibility of asphyxia. Apgar score and umbilical arterial blood gas analysis should be used to evaluate the prognosis of neonates.
