Abstract : Preeclampsia remains one of the leading causes of maternal and perinatal morbidity and mortality. The present study was conducted to know the relationship between placental location after 28 weeks and occurrence of preeclampsia and FGR., and to compare the outcome of pregnancy with non-lateral (central) and laterally implanted placenta. Place of study: Niloufer hospital, Osmania medical college, Hyderabad. Study period: 18 months. Study design: Longitudinal Observational hospital-based. Procedure of data collection: In this study 200 singleton pregnant women who have come to NILOUFER Hospital, and who were willing to participate in the study were taken. In this study the location of placenta and placental doppler was determined from 28weeks of gestational age. The placenta was classified as non-lateral when it was equally distributed between right and left irrespective of being anterior, posterior, and fundal in position. When 75% or more mass of placenta waste wards one side it was described as lateral. Study analysis: The results of the study will be compiled, tabulated and analyzed by MICROSOFT EXCEL. All 200 patients were followed till delivery for occurrence of preeclampsia as per guidelines. All data was analyzed and statistical significance was determined by Chi-square test and value of p<0.05 was considered statistically significant. Out of 200 patients, 110 members had lateral placenta and 90members had central placenta. Out of 110 members with lateral placenta, 29 patients had preeclampsia and remaining 81, are normal. Out of 90 patients with central placenta, 11 patients developed preeclampsia and remaining 79 are normal. Incidence of preeclampsia in lateral placenta (110) in this study was 26.36%. Incidence of preeclampsia in central group (90) in my study is 12.22%. In this study after applying the Chi Square test, the value is 6.118 and the P value is <0.05 which is statistically significant. Incidences of preeclampsia, IUGR and birth asphyxia were found to be higher in laterally localized placenta cases when compared with those in central localized placenta. This association should prompt the clinician for preeclampsia and IUGR in pregnant women with laterally localized placentas.
