Fetal Umblical Artery Doppler Indices in Healthy Pregnant Women in Yenagoa, Nigeria.
Introduction: The measurement of fetal umbilical blood flow using Doppler ultrasound is a well-established tool in the management of high-risk pregnancies and has resulted in improved outcomes. However, there is a paucity of data concerning the normal parameters in Nigeria. This study is aimed at assessing the fetal umbilical artery indices in pregnant Nigerian women. Methods: This was a cross-sectional prospective study carried out at the Niger delta university teaching hospital, silhouette radio diagnostic consultants Yenagoa and federal medical center. A total of 400 pregnant women between the gestational ages of 20 - 40 weeks were evaluated within a one-year period using a 2014 Philips HD 11 ultrasound machine equipped with a 3.5Mhz curvilinear probe having colour, pulsed wave and power Doppler facilities. Results: The mean age and BMI were 30 ± 6 years and 29.9±5.76 kg/m2respectively while the mean umbilical artery systolic velocity and end-diastolic velocities were 40.07± 8.99m/s and 17.44±6.37m respectively. The mean resistivity index (RI) is 0.57. There was a negative correlation of RI with Gestational age (P<0.05). Conclusion: Fetal umbilical artery Doppler parameters are an essential tool in the management of high-risk pregnancies and have resulted in an improved outcome. This study is to serve as a baseline for further studies with a larger sample size.
