摘　　要：目的:针对胎儿宫内缺氧,分析应用彩色多普勒超声检测大脑中动脉和脐动脉的阻力指标值对临床诊断的影响。方法:回顾性选取2022年1月~2023年12月本院产检提示胎儿缺氧产妇130例纳入观察组,同时另取同一时期本院产检提示胎儿正常的130例产妇纳入对照组,对照组和观察组均通过彩色多普勒超声检查阻力指标,即收缩期峰值流速和舒张期流速比值(S/D)、搏动指数(PI)、阻力指数(RI),并对大脑中与脐动脉阻力指标检查指标工作特征曲线(ROC)进行观察。结果:观察组大脑中动脉的RI、PI、S/D值均较对照组低(P<0.05);观察组脐动脉中的RI、PI、S/D值均较对照组高(P<0.05);观察组大脑中动脉与脐动脉的RI、PI、S/D值均较对照组低(P<0.05);ROC曲线分析结果显示,胎儿缺氧实施彩色多普勒超声对大脑中动脉与脐动脉的RI、PI、S/D值进行检查具有一定的临床诊断价值,且三项指标分别诊断与联合诊断的AUC均>0.800。结论:对于疑似胎儿宫内缺氧的临床诊断中,应用彩色多普勒超声检测脐动脉与大脑中动脉的阻力指标值,发现中动脉的RI、PI、S/D值呈异常下降趋势,而脐动脉阻力指标值均呈异常升高趋势,可为后续治疗提供参考依据。Objective:For fetal intrauterine hypoxia,the effect of applying color Doppler ultrasound to detect the resistance index value of middle cerebral artery and umbilical artery on clinical diagnosis was analyzed.Methods:Retrospectively selected from January 2022 to December 2023 our hospital suggest fetal hypoxia maternal 130 cases into the observation group,while the same period during the fetus of 130 cases into the control group,control group and observation group through color Doppler ultrasound resistance index,namely peak systolic flow rate and diastolic flow rate ratio(S/D),beat index(PI),resistance index(RI),and in the brain and umbilical artery resistance index check index working characteristic curve(ROC).Results:Compared with control group,RI,PI and S/D values of middle cerebral artery were lower in observation group(P<0.05).Compared with control group,the values of RI,PI and S/D in umbilical artery were higher in observation group(P<0.05).Compared with the control group,RI,PI and S/D values of middle cerebral artery and umbilical artery were lower in observation group(P<0.05).The results of ROC curve analysis showed that the RI,PI and S/D values of fetal hypoxia,and the AUC of diagnosis and combined diagnosis of the three indexes were>0.800.Conclusion:In the clinical diagnosis of suspected fetal intrauterine hypoxia,the resistance values of umbilical artery and middle cerebral artery were detected by color ultrasound,and found that the RI,PI and S/D values of middle artery showed an abnormal decreasing trend,while the resistance values of umbilical artery all showed an abnormal increasing trend,which could provide a reference for subsequent treatment.
