Pak Postgrad Med J Jan ;31(3):146-50.

Background: Placenta Previa is one of the major obstetric complication. It is a serious condition that may lead to severe morbidity and mortality. The risk of cesarean and blood loss, particularly, in emergency cesarean section. Objective: To compare the mean blood loss and need for blood or blood products with emergency versus elective cesarean section in females with placenta previa. Study design: Cohort study. Settings: Department of Obstetrics & Gynaecology. Duration: 3 months (April to June 2020). Method: Sample size of 70 patients were enrolled in the study through Non Probability, Consecutive Sampling. Patients of age 20-40 years, presented >24 weeks of pregnancy, with diagnosis of placenta previa were included. Then females were booked and were followed-up in OPD till delivery. Emergency cesarean section was done if active labor and bleeding started while elective cesarean was done on given date for delivery. Intraoperative blood loss and need for blood or blood components transfusion was noted. Data was recorded on proforma and analyzed by using SPSS version 22. Results: The mean age of females in emergency group was 30.80 ± 4.36 years and mean age of females in elective group was 31.06 ± 3.76 years. The mean gestational age of females at delivery in emergency group was 35.74 ± 2.89 weeks and in elective group was37.54 ± 0.70 weeks. The average blood loss during emergency caesarean section was 1471.43 ± 891.65 ml while during elective cesarean section, average blood loss was 1042.86 ± 402.41 ml (p<0.05). In emergency caesarean group, 7 (20%) did not require blood transfusion while 28 (80%) required blood transfusion. In elective caesarean group, 21 (60%) did not require blood transfusion while 14 (40%) required blood transfusion (p<0.05). Conclusion: Though this study, we found significantly higher blood loss and need for blood transfusion in emergency caesarean section as compared to elective caesarean sections for placenta previa.
