摘　　要：目的 探讨彩色多普勒血流成像(CDFI)联合无应激试验(NST)对孕晚期孕妇胎儿宫内窘迫诊断效能的影响,以期为临床完善科学有效诊断方案提供可参考依据。方法 选择我院2021年1月至2023年3月收治的孕晚期孕妇98例作研究对象,依据分娩结果将孕妇分为窘迫组(37例)、未窘迫组(61例),进行CDFI、NST检查,统计2组血流频谱参数[阻力指数(RI)、搏动指数(PI)、收缩期与舒张期流速比值(S/D)]、NST检查结果、阳性率,并使用受试者工作特征(ROC)曲线分析CDFI、NST以及联合检查诊断效能。结果 窘迫组大脑中动脉(MCA)的PI、RI、S/D低于未窘迫组,脐动脉(UA)的PI、RI、S/D高于未窘迫组(P<0.05);窘迫组NST胎心监护异常率高于未窘迫组(P<0.05);窘迫组CDFI、NST、联合检查的阳性率高于未窘迫组(P<0.05);ROC曲线结果,联合检查胎儿宫内窘迫的AUC值是0.894、灵敏度95%、特异度93%高于CDFI、NST单一诊断效能(P<0.05)。结论NST联合CDFI对于孕晚期孕妇胎儿宫内窘迫的诊断效能较高,可为临床早期干预提供数据支持。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 for 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 fetal distress 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.
