A Study of Colour Doppler in High Risk Pregnancies
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Doppler ultrasound enables a better understanding of the hemodynamic changes and has therefore become one of the most important clinical tools for fetomaternal surveillance in high risk pregnancies. It can be credited with causing a significant decrease in perinatal mortality and morbidity. The objective of the study was to analyse the Doppler flow patterns by ultrasound in high risk pregnancies, and also compare these patterns with that of normal pregnancies. Material and methods: It is a randomized control trial study conducted among 100 pregnant women (50 study group and 50 control group) conducted from April, 2016 to November 2017. 50 Women with pregnancies deemed by the investigators to be at high risk namely preeclampsia, IUGR, other hypertensive disorders of pregnancies, gestational DM were selected for the study group whereas 50 women with normal pregnancies were selected in control group and their accurate GA was established by 2nd trimester scan. Patients were assessed for fetal wellbeing colour Doppler flow in umbilical artery and middle cerebral artery and middle cerebral artery. Results: In our study A/B ratio, resistance index, pulsatility index values in MCA steadily declined as compared to study group from 28-36 weeks of gestation with slight increase around 34-36 weeks. 90% cases were pre-eclampsia, 6% were gestational DM and 45 cases were PIH with IUGR. Mean birth weight at different gestational period were significantly less compared to study group. At 28-32 weeks of gestation misoprostol was preferred method of induction and after 36 weeks of gestation elective caesarean section was preferred route for delivery. Total 92% live births and 8% of them were still births were recorded. Conclusion: Non-invasive methods like color Doppler velocitometery is a valuable tool to assess fetal wellbeing.
