摘　　要：目的分析彩色多普勒超声血流显像检测收缩期峰值流速/舒张末期流速(S/D)值预测胎儿宫内缺氧的应用价值。方法选取2022年1月-2023年12月信丰县中医院收治的疑似胎儿宫内缺氧产妇26例作为研究对象,并将其纳入研究组,另选择同期正常产妇26例作为对照组。两组均行超声脐血流检测。比较两组S/D值正常率、脐血流收缩期末血流速度(Vs)、舒张期末血流速度(Vd)、搏动指数(PI)、脐动脉阻力指数(RI)、S/D值。并以妊娠结果为金标准,分析超声脐血流S/D值预测胎儿宫内缺氧的价值。结果研究组S/D值正常比例低于对照组(P<0.05);研究组Vs、S/D、RI、PI水平高于对照组,而Vd水平低于对照组(P<0.05);研究组26例产妇妊娠结果显示有24例为胎儿宫内缺氧,超声脐血流S/D值检测诊断发现26例患者中有24例阳性患者(真阳性23例),阳性预测值为95.83%、阴性预测值为50.00%、灵敏度为95.83%、特异度为50.00%、检出准确度为92.31%。结论超声脐血流S/D值检测在胎儿宫内缺氧预测中具有一定的应用价值,具有较高的准确率、敏感度、阳性预测值。Objective To analyze the application value of peak systolic velocity/end diastolic velocity(S/D)value detected by color Doppler ultrasound blood flow imaging in predicting fetal intrauterine hypoxia.Methods A total of 26 pregnant women with suspected intrauterine hypoxia admitted to Xinfeng County Hospital of Traditional Chinese Medicine from January 2022 to December 2023 were selected as the study subjects and included in the study group,and 26 normal pregnant women during the same period were selected as the control group.Ultrasound umbilical blood flow detection was performed in both groups.The normal rate of S/D value,end-systolic blood flow velocity(Vs),end-diastolic blood flow velocity(Vd),pulsatility index(PI),umbilical artery resistance index(RI)and peak-to-valley ratio of blood flow velocity(S/D)were compared between the two groups.The value of ultrasound umbilical blood flow S/D value in predicting fetal intrauterine hypoxia was analyzed with pregnancy results as the gold standard.Results The normal proportion of S/D value in the study group was lower than that in the control group(P<0.05).The levels of Vs,S/D,RI and PI in the study group were higher than those in the control group,while the level of Vd was lower than that in the control group(P<0.05).In the study group,26 cases of maternal pregnancy results showed that 24 cases were fetal intrauterine hypoxia.Ultrasound umbilical blood flow S/D value detection and diagnosis found 24 positive patients(23 true positive patients)in 26 patients,the positive predictive value was 95.83%,the negative predictive value was 50.00%,the sensitivity was 95.83%,the specificity was 50.00%,and the detection accuracy was 92.31%.Conclusion Ultrasound umbilical blood flow S/D value detection has certain application value in the prediction of fetal intrauterine hypoxia,with high accuracy,sensitivity and positive predictive value.
