Assessment of fetal wellbeing by color Doppler ultrasonography in severe pre-eclampsia patients

Abstract

Background: By seeing and analyzing blood flow in both maternal and fetal veins, color Doppler ultrasound is a useful technique for evaluating fetal health, especially in high-risk pregnancies. Objective: Color Doppler ultrasound is used to evaluate the fetal health in patients with severe pre-eclampsia. Methodology: 50 randomly chosen individuals between the ages of 16 and 35 who had Doppler sonography of their umbilical, middle cerebral, and uterine arteries performed between weeks 29 and 40 of pregnancy participated in this prospective study. Prior to then, each patient's informed permission was obtained. After that, a thorough history and clinical examination are performed on each patient. This six-month study was carried out in the Department of Obstetrics and Gynecology at the Dhaka Medical College Hospital (DMCH), Dhaka, from December 22, 2023, to June 21, 2024. After data collection is complete, statistical analysis will be performed. Result: Accordingly, 70%, 68%, and 62% of the patients in my study had aberrant color Doppler blood flow indices for 70% of deliveries at 34±3.7 weeks gestation, while 30% of deliveries occurred at 38±1.6 weeks gestation, with normal color Doppler indices. Of the 50 patients who participated in my study, 5 (10%) experienced spontaneous NVD, 15 (30%) experienced NVD during induction, and 30 (60%) underwent caesarian section. Of the 34 patients (68%) with aberrant umbilical artery blood flow indices, 33 patients (66%) had babies that were undersized for gestational age. Conclusion: Evaluation of color Doppler maternal uterine artery, fetal middle cerebral and umbilical artery is useful tool for diagnosis of IUGR and prediction of adverse fetal wellbeing.
