Background & Method: The aim of this study is to study Observational retrospective study on maternal and fetal Outcome in preeclampsia in pregnancy. Result: In our Study over 980cases. 200 patients was of severe preeclampsia. 780 was mild to moderate preeclampsia. Out of with 100 have macerated iud. 400 have live birth. 200 have preterm birth. Neonatal Death 20. Birth asphyxia 160. In our study maternal age of mostly 20 to 35 taken. Mostly patient were reffered with poor antenatal counseling and coverage. They only have one to two antenatal visit. Maximum cases 60% of preeclampsia seen at age of 26 to 35, >35 age 25 % cases and 15% below 26. In elderly primi almost 60% cases have preeclampsia. Eclampsia is mostly associated with young age primi. Complications like HELLP syndrome mostly associated with severe preeclampsia. Conclusion: Preeclampsia and eclampsia continue to be significant causes of maternal and fetal morbidity and mortality.Though prevention is not possible, it is important to recognise early warning symptoms and signs so that life threatening complications can be averted. Provision of quality antenatal health care services, increasing patient awareness about warning symptoms, investigations, timely delivery and intensive monitoring in the intrapartum and postpartum period have the potential to improve maternal and perinatal outcome. Education and empowerment of women and accessible health care especially to the socioeconomically deprived and rural population is the need of the hour.
