Abstract：Objective:To evaluate the practical value of ultrasonic doppler flow imaging of umbilical artery on prenatal examination.Methods:Umbilical artery blood flow was detected with ultrasonic doppler flow imaging in 260 gravidas(pregnant age ranging from 37 to 42 weeks),and S/D value of the umbilical artery blood flow imaging and results of non stress test(NST) were compared with birth weight,contamination of amniotic fluid,entanglement or shortage of umbilical cord,and birth asphyxia.Results:In 69 cases with abnormal S/D value,there were 8 infants(11.6%) with low birth weight,30(43.5%) with contamination of amniotic fluid,20(29.0%) with entanglement or shortage of umbilical cord,and 12(17.4%) with birth asphyxia.The incidence of perinatal complications in abnormal S/D group was much higher than that in normal S/D group.Conclusion:Ultrasonic doppler flow imaging of umbilical artery may play an important role in judging the fetal abnormality;when combined with NST,it is able to enhance the quality of prenatal care and predict the perinatal prognosis.
