Hypertensive disorders are the most common medical complications of pregnancy (7.15%). Doppler analysis of umbilical artery S/D ratio PI and RI, absent or reversal of EDV were evaluated and follow up results studied in severe preeclampsia women between 26 to 40 weeks. Doppler analysis of Uterine Artery and Middle Cerebral Artery is also studied. Doppler study guides in decision making and follows up in severe preeclampsia and guides in reducing perinatal morbidity and mortality. Period of Study: This is a prospective randomised study conducted at Niloufer Hospital for Women and Children Red Hills Hyderabad from September 2011 to June 2014. Material and Methods: 100 pregnant women with severe preeclampsia who attended Antenatal Out-Patient Department and got admitted in Emergency ward underwent Umbilical artery velocimetry by means of a Colour doppler vision (6000 Toshiba corp Tokyo Japan) using 3.5_5 MHZ Trasabdominal traducer. Results: Total number of 100 women were studied. In this 60 women had foetuses with abnormal umbilical artery flow velocimetry and 40 had normal umbilical artery flow velocimetry. The average birth weight and diagnosis to delivery interval were lower in foetuses with abnormal umbilical artery doppler. Admission to neonatal intensive care unit is high. The APGAR score at 1 minute is <7 in 20 women with abnormal umbilical artery doppler compared to 17 women with normal umbilical artery doppler. Compared to 32 women with normal umbilical artery doppler, the APGAR score is more than 7 in 31 women with abnormal umbilical artery Doppler. P = 0.639647 and chi-square statistic = 0.2192, the result is statistically not significant at p-value < 0.05, implying that APGAR scores are not dependent on doppler findings alone. Conclusion: Doppler study guides obstetrician to assess the physiological status of the foetus and it helps in identifying the changes in the foetal circulation. This study suggests that doppler assessment of foe to placental circulation including umbilical artery is a better prognostic indicator in severe PE and helps in timely intervention. The foetuses with normal artery flow velocimetry area at a lower risk of having poor APGAR score than those with abnormal velocimetry and NICU admissions are less with normal umbilical artery flow velocimetry. The average birth weight of neonates with abnormal umbilical artery was lower compared to neonates with normal umbilical artery velocimetry.
