Predictive Value of Fetal Umbilical Blood Flow Monitoring and Fetal Heart Rate Monitoring in High-Risk Pregnancy
Objective To explore the predictive value of fetal umbilical blood flow monitoring and fetal heart rate monitoring in high-risk pregnancy.Methods From March 2021 to March 2023,the clinical data of 180 high-risk pregnant women admitted to the department of obstetrics and gynecology,Air Force Medical Center,PLA were retrospectively analyzed.All the eligible subjects were monitored by fetal umbilical blood flow and fetal heart rate.According to the results,the subjects were divided into four groups:Group A,Group B,Group C and Group D.The childbirth indicators of the research subjects(cesarean section,fetal distress,umbilical cord entanglement,oligohydramnios,meconium contamination,Apgar score within 1 minute after birth);umbilical blood flow indicators[umbilical artery blood flow S/D value,umbilical artery vascular resistance index(RI),umbilical artery pulsation index(PI)]were compered.Results The incidence of adverse delivery in group D was the highest in cesarean section(79.17%),fetal distress(50.00%),umbilical cord entanglement(50.00%),oligohydramnios(70.83%),and meconium contamination(100.00%),which was significantly higher than that in group A and group B(P<0.05).The Apgar score of 8-10 within 1 minute after birth in Group A was higher than that in Group B,C,D(P<0.05).The Apgar score of 8-10 points within 1 minute of birth of newborns in Group B and C was higher than that of group D(P<0.05).The umbilical artery blood flow index(S/D,RI,PI)in Group D was higher than that in Group A,B,C,the difference was statistically significant(all P<0.05).Conclusion The application of fetal umbilical blood flow monitoring and fetal heart rate monitoring in high risk pregnant women can improve the accuracy of prediction of adverse pregnancy outcomes.It is helpful to the treatment and management of perinatal period,and reduce the occurrence of adverse delivery outcomes,improve the quality of delivery.
