Relationship between severe preeclampsia hemodynamics of fetal umbilical artery and perinatal prognosis

Objective To probe the relationship between severe preeclampsia hemodynamics of fetal umbilical artery and perinatal prognosis.Methods Color Doppler flow imaging was applied to detect the systolic and diastolic velocity ratios(S/D),pulsatility indices(PI) and resistance indices(RI) of umbilical artery of 100 severe preeclampsia pregnant women(observed group) and 100 normal pregnant women(control group) in same period.At the same time,the intrauterine growth of the fetus were observed and the perinatal outcomes were followed up.Results The rate of fetal umbilical artery hemodynamic abnormalities and the rate of adverse perinatal outcome of observed group was significantly higher than that of control group(P0.005).Among the observed group,the rate of adverse perinatal outcome of abnormal fetal umbilical artery hemodynamic group was significantly higher than that of normal group(P0.05).Conclusion Due to disturbance of placenta-fetal circulation,the blood flow resistance of fetal umbilical artery among the severe preeclampsia women was increased,so it was correlated with adverse perinatal grognosis.It was some clinic value to predict perinatal prognosis that umbilical artery hemodynamic change among severe preeclampsia women detected by Color Doppler.
