Clinical Value of Ultrasound Umbilical Blood Flow S/D Value Monitoring in Predicting Fetal Intrauterine Hypoxia
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.
