Background: Placental abruption is defined as the complete or partial separation of a normally implanted placenta after 28 weeks of pregnancy but before delivery.It is a major obstetric complication associated with an increased risk of fetal and maternal morbidity & mortality globally. Aim: This study was conducted to examine the impact of the abruption severity and the onset-to-delivery time on the maternal and neonatal outcomes in cases of placental abruption. Material and methods: All the case sheets of the women who were diagnosed with placental abruption at 28 weeks of gestation and beyond in tertiary care hospital at R.L. Jalappa Hospital, Kolar from January 2018 to December 2022 have been reviewed. The fetomaternal outcome were recorded by the parity, gestational age, Hemoglobin at admission, risk factor of placental abruption, admission to delivery interval, mode of delivery, massive transfusion, Apgar score, ICU&NICU admission. All the data collected were entered into proformas for further statistical analysis.Data was analyzed with Microsoft Excel and Statistical Package for Social Sciences (SPSS) software version 22.0. Data was also represented using appropriate diagrams like bar diagram, pie diagram. Mean and standard deviation of the quantitative variables were measured. P value ≤0.05 was taken as significant. Results: In this study, Total 74 participants were included. Majority 40 (54.05%) of the total subjects were aged between 21 to 30 years. 34 subjects (45.94%) were booked. 44 (59.45%) subjects belonged to multigravida group. Most of the subjects belonged to the gestational age of 36-40 weeks accounting for 36 (48.64%) cases. In our study, 26 (35.13%) had Grade 2 abruption, 22 (29.72%) subjects had Grade 3A abruption. 38 (51.35%) subjects underwent LSCS, 30 (40.54%) had vaginal delivery. 12 subjects were admitted to ICU. 29 (63.05%) neonates were admitted in NICU. Conclusion: The severity of placental abruption is significantly correlated with poor fetal outcome and there were significant impact of severity of abruption and onset to delivery on maternal outcome.
