Application value of the uterine artery blood flow parameters detected by Doppler ultrasound in predicting the high-risk pregnancy outcome

Objective:To investigate the clinical value of the uterine artery blood flow detected by Doppler ultrasound in predicting the high-risk pregnancy outcome.Methods:One hundred and twenty high-risk pregnancy patients and 100 normal pregnant women were divided into the observation group and control group, respectively.The peak systolic velocity/end diastolic velocity(S/D), uterine artery score, pulsatility index(PI) and resistance index(RI) between two groups were analyzed, and the ROC curve were established.The different S/D values of maternity, and the weight, growth restriction and proportion of suffocation of newborn in observation group were recorded.Results:The S/D value, PI and RI in observation group(2.93±1.04, 0.73±0.19 and 1.39±0.82) were significantly higher than those in control group(2.21±0.29, 0.54±0.12 and 1.08±0.37), respectively(P<0.01).In observation group, the newborn weight in puerperal with S/D value≥2.8(3 192±204)g was significantly lower than that in puerperal with S/D value<2.8(3 327±284 )g(P<0.01).In observation group, the growth restriction and asphyxia rates of newborn in puerperal with S/D value≥2.8(68.12% and 42.03%) were significantly higher than those in puerperal with S/D value<2.8(19.61% and 13.73%), respectively(P<0.01).The premature, SGA, PI, RI, SD and area under the ROC curve were gradually decreased in observation group.Conclusions:The high-frequency ultrasonic doppler of uterine artery can detect the hemodynamic parameters in high-risk pregnancy.The patient's condition can be determined by S/D value, which has certain clinic value.
