摘要
目的:探究胎心监护联合超声脐动脉血流动力学指标对宫内窘迫的临床预测效果。方法:选取2020年4月~2022年4月本院收治的孕晚期高危妊娠孕妇共计104例,全部研究对象均进行电子胎心监护以及超声脐动脉血流动力学检查,以上述研究对象的最终分娩结果(是否发生胎儿窘迫)作为诊断金标准;探究上述两种检测方案应用于宫内窘迫的预测效能;根据研究对象是否发生宫内窘迫将其划分为窘迫组(n=35)、非窘迫组(n=69);比较两组研究对象游离段脐动脉收缩期最大血流速度/舒张末期血流速度比值(S/D)、阻力值(RI)以及搏动指数(PI)水平。结果:在全部104例研究对象中,最终发生宫内窘迫者35例;未发生宫内窘迫者69例。在两种评估方案中,胎心监测对宫内窘迫预测的灵敏度为85.71%、特异度为86.96%、准确率为86.54%;脐动脉血流超声对宫内窘迫预测的灵敏度为91.43%、特异度为89.86%、准确率为90.38%;两种检测方法联合预测宫内窘迫的灵敏度为94.29%、特异度为92.75%、准确率为93.27%;结果对比可知,两种方法联合预测宫内窘迫的灵敏度、特异度以及准确率显著高于单一方法的预测。对比结果显示,窘迫组研究对象的脐动脉以及大脑中动脉的S/D、RI以及PI水平均高于非窘迫组(P<0.05)。结论:胎心监护联合超声脐动脉血流动力学相比单一项目,具有更高的灵敏度、特异度以及准确率,具有较高的应用价值。
Objective:To explore the predictive efficacy of fetal heart monitoring combined with ultrasound of umbilical artery hemodynamics for intrauterine distress.Methods:A total of 104 high risk pregnant women in the third trimester were selected from April 2020 to April 2022.All of them were monitored by electronic fetal heart rate monitoring and hemodynamics ultrasound examination of umbilical artery,to explore the predictive efficacy of fetal heart rate monitoring combined with umbilical artery hemodynamics ultrasound in the diagnosis of fetal distress.The subjects were divided into distress group(n=35)and nondistress group(n=69)according to the occurrence of intrauterine distress,the ratio of maximum systolic velocity to end diastolic velocity(S/D),resistance(RI)and pulsatility index(PI)of umbilical artery and middle cerebral artery in late pregnancy.Results:Of the 104 cases,35 cases had intrauterine distress and 69 cases had no intrauterine distress.The sensitivity,specificity and accuracy of fetal heart rate monitoring were 85.71%,86.96%and 86.54%,respectively.The sensitivity,specificity and accuracy of UCB were 91.43%,89.86%and 90.38%,respectively.The sensitivity,specificity and accuracy of the two methods were 94.29%,92.75%and 93.27%respectively,the sensitivity,specificity and accuracy of the two methods were significantly higher than those of the single method.The results showed that the S/D,RI and PI of umbilical artery and middle cerebral artery in the group of distress were significantly higher than those in the group of non-distress(P<0.05).Conclusion:Fetal heart monitoring combined with ultrasound of the umbilical artery hemodynamics for intrauterine distress has higher sensitivity,specificity and accuracy than a single item,and is of higher application value.
