Objective To explore the effect of color Doppler flow imaging(CDFI)combined with non-stress test(NST)on the diagnosis of intrauterine distress in high-risk pregnant women in late pregnancy,to provide reference fdr clinical improvement of scientific and effective diagnosis scheme.Methods A total of 98 high-risk pregnant women in late pregnancy admitted to our hospital from January 2021 to March 2023 were selected as research objects.According to delivery results,pregnant women were divided into a distress group(37 cases)and a non-distress group(61 cases),all of which underwent CDFI and NST examination.Blood flow spectrum parameters[resistance index(RI),pulsation index(PI),systolic to diastolic flow rate ratio(S/D)],NST test results,and positive rate of the two groups were analyzed,and the receiver operating characteristic(ROC)was used to analyze the diagnostic efficiency of CDFI,NST,and combined test.Results The PI,RI,and S/D of middle cerebral artery(MCA)in the distress group were lower than those in no distress group,and the PI,RI,and S/D of the umbilical artery(UA)were higher than those in no distress group(P＜0.05).The abnormal rate of NST fetal heart monitoring in the distress group was higher than that in the non-distress group(P＜0.05).The positive rate of CDFI,NST and combined examination in the distress group was higher than that in the non-distress group(P＜0.05).ROC curve results showed that the AUC value of combined examination for fetaldistress was 0.894,the sensitivity was 95％,and the specificity was 93％,which were significantly higher than the single diagnostic efficacy of CDFI and NST(P＜0.05).Conclusion NST combined with CDFI has high diagnostic efficacy for fetal distress in high-risk pregnant women in late pregnancy,which can provide data support for early clinical intervention.
