Relationship between ductus venosus blood flow and chronic fetal distress

Objective:To explore the relationship between ductus venosus blood flow and chronic fetal distress.Methods:100 pregnant women (gestational weeks:37～41 weeks) were divided into two groups:control group (50 cases) and chronic fetal distress group (50 cases). All fetal ductus venosus blood flow parameters including ventricular systole,ventricular diastole,atrial systole,pulsatility index,resistance index were observed.All the neonatal outcomes including body weights,1 minute Apgar scores,pH values of umbilical vein,oxygen saturation of umbilical artery were observed.Results:①The peak values of ventricular systole,ventricular diastole and atrial systole in chronic fetal distress group were lower than those in control group,while pulsatility index and resistance index reversed (P0.05).②The body weight of neonates,Apgar score,pH value of umbilical vein and oxygen saturation of umbilical artery in chronic fetal distress group were lower than those in control group (P0.05).③There was negative correlation between ductus venosus blood flow parameters and body weight of neonates,Apgar score,pH value of umbilical vein,oxygen saturation of umbilical artery.Conclusion:The ductus venosus blood flow parameters change in children with chronic fetal distress,the monitoring of ductus venosus blood flow parameters can prevent bad perinatal outcomes.
