摘要
目的:探究多普勒超声检测孕晚期脐动脉血流动力学参数对胎儿窘迫的诊断价值。方法:选取2021年1月~2023年12月泉州市光前医院产科住院分娩的胎儿窘迫产妇115例作为观察组,另选取同期于泉州市光前医院产科接受分娩的健康孕妇115例作为对照组。所有孕妇均接受多普勒超声检测,包括脐动脉胎盘附着部、漂浮部、脐轮部的血流参数。对比对照组和观察组孕妇脐动脉胎盘附着部、漂浮部、脐轮部收缩期峰值流速与舒张末期流速比(S/D)、阻力指数(RI)、搏动指数(PI)的血流参数;受试者操作特征曲线分析S/D、RI、PI血流参数对胎儿窘迫的诊断价值。结果:观察组附着部S/D、RI、PI血流参数均显著高于对照组(P<0.05);观察组漂浮部S/D、RI、PI血流参数均显著高于对照组(P<0.05);观察组脐轮部S/D、RI、PI血流参数均显著高于对照组(P<0.05);联合S/D、RI、PI血流参数对胎儿窘迫的检测诊断率高于单独检测(P<0.05),且联合检测的特异度和敏感度均显著更高。结论:对于孕晚期孕妇而言,对其行多普勒超声脐动脉血流动力学参数检测,可提升临床胎儿窘迫的检出率和诊断价值。
Objective:To explore the diagnostic value of Doppler ultrasonography in detecting umbilical artery hemodynamics parameters in late pregnancy for fetal distress.Methods:A total of 115 women with fetal distress who gave birth in the Obstetrics Department of Quanzhou Guangqian Hospital from January 2021 to December 2023 were selected as the observation group,and 115 healthy pregnant women who gave birth in Quanzhou Guangqian Hospital Ultrasound Department during the same period were selected as the control group.The blood flow parameters of umbilical artery placenta attachment,floating part and umbilical wheel part were measured by Doppler ultrasound in all pregnant women.The blood flow parameters of umbilical artery,placenta attachment,floating,umbilical wheel,S/D,RI and PI were compared between control group and observation group.The diagnostic value of S/D,RI and PI flow parameters in fetal distress was analyzed by ROC.Results:Blood flow parameters of S/D,RI and PI in the attachment part of the observation group were significantly higher than those in the control group(P<0.05).The blood flow parameters of S/D,RI and PI in the floating section of the observation group were significantly higher than those of the control group(P<0.05).The blood flow parameters of S/D,RI and PI in the umbilical wheel in the observation group were significantly higher than those in the control group(P<0.05).The diagnostic rate of combined S/D,RI and PI blood flow parameters for fetal distress was higher than that of single detection(P<0.05),and the specificity and sensitivity of combined detection were significantly higher.Conclusion:For pregnant women in the third trimester,the detection rate and diagnostic value of umbilical artery hemodynamics parameters by Doppler ultrasound can improve the clinical fetal distress.
