目的研究晚孕期胎儿大脑中动脉(MCA)与子宫动脉(UtA)的血流参数对胎儿宫内窘迫的诊断价值. 方法应用彩色多普勒超声对407例晚孕期单胎胎儿进行检查,按检查结果分缺氧高危组67例,健康组340例.分别记录两组胎儿的MCA及UtA的搏动指数(PI)、阻力指数(RI)、心室收缩期峰值流速/心室舒张期末血流速度(S/D).计算UtA血流参数与MCA血流参数的比值.对两组胎儿的各血流参数进行分析. 结果缺氧高危组胎儿UtA-PI、UtA-RI、UtA-S/D测值均高于正常组(均P＜0.01),MCA-PI低于正常组(P＜0.05),UtA与MCA血流参数的比值均高于正常组(均P＜0.01).以(UtA/MCA)-PI≥0.72,(UtA/MCA)-RI≥0.81,(UtA/MCA)-S/D≥0.74为标准,其预测胎儿缺氧的灵敏度为63.3%,特异度为90.2%. 结论 UtA血流参数与MCA血流参数的比值可在产前预测胎儿宫内缺氧.

Objective To evaluate the dinical value of MCA and UtA Doppler parameters for the predication of fetus hypoxia. Methods 407 singleton pregnancies at the third trimester were underwent Color Doppler,of which 67 cases were in high risk group and 340 cases were in control group.UtA-PI、UtA-RI、UtA-S/D、MCA-PI、MCA-RI and MCA-S/D were all measured.The ratio of UtA to MCA was calculated.All parameters were analyzed. Results In high risk group,UtA-PI,UmA-RI and UtA-S/D were all higher than that in control group(all P＜0.01),MCA-PI is lower than that in control group(P＜0.05),and the ratio of UtA to MCA was higher than that in control group(all P＜0.01).By the standards of(UtA/MCA)-PI ≥ 0.72,(UtA/MCA)-RI ≥ 0.81,and(UtA/MCA)-S/D ≥ 0.74,the predication sensitivity of fetus hypoxia was 63.3%,and the specificity was 90.2%. Conclusion The ratio of UtA to MCA could predict fetus hypoxia.
