Clinical value of ultrasound umbilical blood flow S/D combined with fetal heart rate monitoring in predicting intrauterine hypoxia

Objective To analysis of the clinical value of the peak ratio (S ≤ D) of flow velocity end-systolic to end-diastolic of umbilical blood by ultrasound combined with fetal Heart monitoring in predicting fetal intrauterine hypoxia.Methods From April2016 to August 2017, 174 pregnant women were selected. Ultrasound umbilical blood flow S/D and fetal heart rate monitoring were performed among the selected pregnant women. The above results were analyzed and compared with the diagnosis of fetal intrauterine hypoxia neonatal by Apgar score.Results Fetal heart rate monitoring showed that unresponsive type accounted for 10.92%.Ultrasound umbilical blood flow S/D≥3 accounted for 13.22%. Apgar score≤7 accounted for 10.34%. The detection rate of fetal distress in reactive type and S/D < 3 (3.47%) was lower than that in unresponsive type and S/D ≥3 (66. 67%). The difference was statistically significant (P<0.05).Conclusion Ultrasound umbilical blood flow S/D combined with fetal heart rate monitoring can predict fetal intrauterine hypoxia with high diagnostic accuracy. They are safe and non-invasive and can be used as an effective scheme for predicting fetal intrauterine hypoxia.
