摘　　要：目的分析不同孕龄超声脐动脉血流参数与胎儿窘迫的关系。方法选择2019年10月至2021年3月扬州大学医学院附属沭阳医院进行产前检查的136名孕妇作为研究对象,根据孕龄将其分为4~12+周组(38名)、13~27+周组(41名)、28~40周组(57名)。比较三组胎儿窘迫发生率,脐动脉学参数[搏动指数(PI)、阻力指数(RI)、收缩期峰值流速/舒张末期流速(S/D)];分析不同孕龄脐动脉血流参数与胎儿窘迫的相关性。结果三组胎儿窘迫发生率比较,差异有统计学意义(P<0.05)。4~12+周组PI、RI、S/D值高于13~27+周组和28~40周组,且13~27+周组PI、RI、S/D值高于28~40周组,差异有统计学意义(P<0.05)。不同孕龄PI、RI、S/D与胎儿窘迫的发生率呈正相关(r>0,P<0.05)。结论不同孕龄产妇脐动脉血流参数PI、RI、S/D值存在差异,PI、RI、S/D值与胎儿窘迫发生率呈正相关。Objective To analyze the relationship between ultrasound umbilical artery blood flow parameters and fetal distress at different gestational ages.Methods A total of 136 pregnant women who underwent prenatal examination in the Affiliate Shuyang Hospital,College of Medicine,Yangzhou University from October 2019 to March 2021 were selected as the research objects.According to the gestational age,they were divided into 4-12+weeks group(38 pregnant),13-27+weeks group(41 pregnant),and 28-40 weeks group(57 pregnant).The incidence of fetal distress,parameters of umbilical artery(pulse index[PI],resistance index[RI],and peak systolic flow rate/end diastolic flow rate[S/D])were compared among three groups;the correlation between umbilical artery blood flow parameters of different gestational ages and fetal distress was analyzed.Results There was statistical difference in the incidence of fetal distress among three groups(P<0.05).PI,RI,and S/D values in 4-12+weeks group were higher than those in 13-27+weeks group and 28-40 weeks group,and PI,RI,and S/D values in 13-27+weeks group were higher than those in 28-40 weeks group,and the differences were statistically significant(P<0.05).The incidence of fetal distress was positively correlated with PI,RI,and S/D values at different gestational ages(r>0,P<0.05).Conclusion PI,RI,and S/D values of umbilical artery blood flow were different in different gestational ages,and PI,RI,and S/D values were positively correlated with the incidence of fetal distress.
