Descriptive study of blood transfusion practices in women undergoing cesarean delivery

Abstract

To study the blood transfusion practices in women undergoing cesarean delivery at a tertiary care centre in northern India. This was a prospective study conducted in 1769 women who underwent cesarean section at a tertiary centre hospital from May 2008 to November 2009. A comprehensive predesigned proforma was filled in for each woman. Data related to antenatal, intrapartum and postnatal events was recorded and compared between women receiving blood transfusion during cesarean section and women not receiving blood transfusion. The cesarean section rate was 26% and the blood transfusion rate was 12.21%. The overall crossmatch transfusion ratio in our study was 5.46:1. After multiple regression logistic analysis factors, like placenta previa (OR 15.19, 95% CI 9.28-24.82), anemia (OR 9.93, 95% CI 5.17-19.06), blood loss >1000 mL (OR 5.97, 95% CI 4.32-8.24), abruptio (OR 4.18, 95% CI 2.02-8.62), intraoperative complications, like uterine incision extension, uterine atony, hysterectomy (OR 2.69, 95% CI 1.70-4.24), general anesthesia (2.48, 95% CI 1.70-3.61) and inadequate antenatal supervision (OR 1.59, 95% CI 1.05-2.42) were found to be significantly associated with a higher risk for blood transfusion during cesarean section. Routine crossmatching of blood for all women prior to cesarean section needs to be reviewed. Cesarean sections performed on women with high risk factors for blood transfusion can have sudden and significant blood loss and thus adequate blood arrangement prior to cesarean section is justified only in this group of women and not in all women.
