Background: Preeclampsia is main cause of morbidity and mortality both mother and fetus. Preeclampsia occurs in 10-17% of pregnancies. Preeclampsia was divided into early onset preeclampsia is occur at less <34 weeks of gestation age and late onset preeclampsia is occur at >34 weeks of gestation age. Early and late onset preeclampsia have different etiology and should be considered as different disease as there are difference in clinical manifestation, maternal and perinatal outcome, prognosis and complication.Methods: An analytic observational study involving retrospective data done at RL Jalappa Hospital, Sri Devaraj Urs Medical College, Kolar. 217 women with singleton pregnancies with Pre eclampsia who were admitted and delivered in our hospital between June 2016 and May 2017 were recruited for this retrospective study.Results: The results showed that the incidence of EOPE (27.6%) was lower than LOPE (72.4%). Diastolic blood pressure is significantly higher in EOPE compared to LOPE. Complications in perinatal outcomes such as low birth weight (<2500 gram) are more in EOPE (98.3%) compared to LOPE (45.2%) and asphyxia is more on EOPE (11.7%) compared to LOPE (1.3%). Stillbirth in EOPE (15%) is more than LOPE group (3.2%).Conclusions: It is observed that EOPE incidence rate is lower than LOPE. Maternal and perinatal complications are greater in the EOPE group.
