摘　　要：目的探究超声检测主要动脉血流参数在胎儿窘迫(FD)预测中的效能。方法选择2021年5月至2023年5月许昌市人民医院收治FD孕妇120例作为观察组,选取同期于许昌市人民医院检查正常孕妇100例作为对照组。两组均行超声检查,比较两组脐动脉(UA)、大脑中动脉(MCA)相关血流参数[血流阻力指数(RI)、搏动指数(PI)、收缩末期峰值与舒张末期峰值比值(S/D)];将FD组根据胎儿严重程度分为轻度组(73例)和重度组(47例),比较两组UA及MCA的血流参数。比较观察组与对照组的RI_(MCA/UA)、PI_(MCA/UA)、S/D_(MCA/UA)水平,分析RI_(MCA/UA)、PI_(MCA/UA)、S/D_(MCA/UA)对FD的诊断价值。结果观察组UA中的RI、PI、S/D均高于对照组(P<0.05),而MCA的RI、PI、S/D均低于对照组(P<0.05);轻度组UA中的RI、PI、S/D均低于重度组(P<0.05),而轻度组MCA的RI、PI、S/D均高于重度组(P<0.05);观察组的RI_(MCA/UA)、PI_(MCA/UA)、S/D_(MCA/UA)水平均低于对照组(P<0.05);采用ROC曲线分析发现,RI_(MCA/UA)、PI_(MCA/UA)、S/D_(MCA/UA)联合诊断FD时的AUC为0.935,高于单一指标的0.881、0.892、0.879。结论超声检测UA及MCA血流参数对临床诊断FD具有较高效能,可帮助判断胎儿宫内状况,提高诊断准确率。Objective To explore the predictive efficiency of main arterial blood flow parameters by ultrasonography in fetal distress(FD).Methods A total of 120 pregnant women with FD and 100 normal pregnant women in Xuchang People’s Hospital were enrolled as observation group and control group from May 2021 to May 2023.The both groups underwent ultrasonography.The blood flow parameters[resistance index(RI),pulsatility index(PI),ratio of peak systolic velocity to end diastolic velocity(S/D)]of umbilical artery(UA)and middle cerebral artery(MCA)were compared between the two groups.According to the severity of FD,pregnant women in observation group were divided into mild group(73 cases)and severe group(47 cases),blood flow parameters of UA and MCA were compared between the two groups.The levels of RI_(MCA/UA),PI_(MCA/UA)and S/D_(MCA/UA)were compared between observation group and control group.The diagnostic value of RI_(MCA/UA),PI_(MCA/UA)and S/D_(MCA/UA)for FD was analyzed.Results RI,PI and S/D of UA in observation group were higher than those in control group(P<0.05),while RI,PI and S/D of MCA were lower than those in control group(P<0.05).RI,PI and S/D of UA in mild group were lower than those in severe group(P<0.05),while RI,PI and S/D of MCA were higher than those in severe group(P<0.05).The levels of RI_(MCA/UA),PI_(MCA/UA)and S/D_(MCA/UA)in observation group were lower than those in control group(P<0.05).ROC curves analysis showed that AUC of RI_(MCA/UA)combined with PI_(MCA/UA)and S/D_(MCA/UA)in the diagnosis of FD was 0.935,greater than that of single index(0.881,0.892,0.879).Conclusion Blood flow parameters of UA and MCA by ultrasonography have high clinical diagnostic efficiency for FD,which is beneficial to determine fetal status and improve diagnostic accuracy rate.
