CLINICAL VALUE OF FETAL HEART RATE MONITORING COMBINED WITH UMBILICAL ARTERY BLOOD FLOW MONITORING FOR LATE TRIMESTER OF PREGNANCY

Objective To explore the clinical value of fetal heart rate monitoring combined with umbilical artery blood flow monitoring for late trimester of pregnancy and prognosis.Methods 264 cases of pregnant women received fetal heart nonstress test and measuring of umbilical artery blood flow and the fetal intrauterine growth was observed.Results 42.0% of newborns in the abnormal fetal heart rate group showed bad prognosis and the rate of cesarean delivery was 60.0%,which was higher than that in the normal fetal heart rate group(P0.01).47.2% of newborns showed bad prognosis.in the umbilical artery blood flow S/D≥3 group and the rate of cesarean delivery was 69.4%,which is higher than that in the S/D3 group.The positive prediction rates confirmed by fetal heart rate monitoring and umbilical artery blood flow monitoring were 42.0% and 47.2% respectively,and the combined positive prediction rate was 70.8%.Conclusion Fetal heart rate monitoring combined with umbilical artery blood flow monitoring can improve the accuracy of diagnosing fetal intrauterine growth to discover fetal distress early and can contribute to fetal prognosis.
