摘要： 本文探讨了胎儿大脑中动脉（MCA）、脐动脉（UA）的彩超参数联合胎心监护对胎儿宫内缺氧的预测价值。选取孕妇400例，根据有无胎儿宫内缺氧分为病例组（72例）和对照组（328例），比较了两组的MCA与UA阻力指标比值（MCA/UA），包括阻力指数（RI）、搏动指数（PI）以及收缩期峰值流速与舒张末期血流速度比值（S/D），分析各参数对胎儿宫内缺氧的评估价值。结果显示，病例组MCA的RI、PI、S/D小于对照组，而UA的RI、PI、S/D高于对照组，且病例组MCA/UA各参数值均低于对照组（P<0.05）。胎心监护提示病例组胎心异常率显著高于对照组（P<0.05）。ROC曲线提示MCA/UA的RI预测胎儿宫内缺氧的曲线下面积为0.628，PI的曲线下面积为0.661，S/D的曲线下面积为0.598。胎心监护评估胎儿宫内缺氧与临床诊断的一致性Kappa检验值为0.661，彩超联合胎心监护评估的一致性Kappa检验值为0.798。将彩超参数MCA、UA与胎心监护联合用于胎儿宫内缺氧的预测，能提高评估准确性，便于尽早采取处理措施。

Abstract: In this paper, the predictive value of the middle cerebral artery (MCA) and umbilical artery (UA) combined with fetal heart monitoring for intrauterine hypoxia were investigated. A total of 400 pregnant women were selected. The patients were divided into case group (72 cases) and control group (328 cases) according to with or without intrauterine hypoxia. The ratio of MCA to UA resistance index (MCA/UA), including RI, PI, and the ratio of systolic peak velocity to end-diastolic flow velocity (S/D), were compared between the two groups to analyze the evaluating effect of the parameters on intrauterine hypoxia. The RI, PI and S/D of MCA in the case group were smaller than that in the control group, while the RI, PI and S/D of UA were higher than that in the control group, and the data of MCA/UA in the case group were lower than that in the control group (P<0.05). Fetal heart monitoring indicated that the abnormal rate of fetal heart in the case group was significantly higher than that in the control group (P<0.05). The ROC curve indicated that the area under the curve predicted by RI, PI and S/D of MCA/UA was 0.628, 0.661 and 0.598, respectively. The consistency between fetal cardiac monitoring and clinical diagnosis on intrauterine hypoxia was 0.661, while the consistency between color Doppler ultrasound combined with fetal cardiac monitoring and clinical diagnosis was 0.798. In conclusion, the use of color Doppler ultrasound parameters of MCA, UA and fetal heart monitoring in the prediction of intrauterine hypoxia can improve the accuracy of evaluation and facilitate early treatment.
