Background: Accurate management of the foetal blood flow & condition is important in order to prevent or reduce perinatal morbidity, mortality & unwanted intervention in pregnancy. Doppler velocimetry helps to identify normal and abnormal flow in foetal arterial and venous circulation. Aim: To evaluate the role Doppler in third trimester pregnancy to predict the foetal outcome, its role in predicting the need of intervention & to compare the role of different Doppler parameters. Material & Methods: An observational, descriptive follow-up study was conducted in our hospital. Various Doppler indices related to Umbilical & Uterine artery and DuctusVenosus were studied & compared for sensitivity & specificity. Results: Four hundred subjects in third trimester of pregnancy were study participants. Half of the subjects had normal Amniotic Fluid Index. Apgar score (AS) was more than or equal to 7 in 55.25% patients. Two (0.5%) subjects with abnormal PI had an AS of 0; 220 (55%) subjects with normal PI has AS of 7 to 10. The S/D ratio of uterine artery was normal in 50% subjects with normal AS & abnormal in 1% subjects with AS of 0. Among all best sensitivity (96.64%) & specificity (99.54%) was noted in Pulsatility Index (PI) of Umbilical artery (placental end). Conclusion: Umbilical artery Doppler &DuctusVenosus waveform indices appear to be the best predictor of poor perinatal outcome. Doppler ultrasound is one of the most important clinical tools of feto-maternal surveillance in pregnancy.
