RESUMEN
Objective To evaluate the dinical value of MCA and UtA Doppler parameters for the predication of fetus hypoxia. Methods407 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. ResultsIn 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%. ConclusionThe ratio of UtA to MCA could predict fetus hypoxia.
