Role of tranexamic acid in reducing blood loss during and after caesarean section

Introduction: Association between caesarean section and intra operative and post operative bleeding is known. Post-partum hemorrhage is still a leading cause for maternal morbidity and mortality. This study will evaluate the efficacy and safety of tranexamic acid in reducing the blood loss after placental delivery following lower segment caesarean section (LSCS) and note any adverse effects. Materials and Methods: A total of 100 women, who underwent elective or emergency primary caesarean section at term between 37 and 41 weeks have been studied prospectively. They were divided into two groups. In the study group of 50, tranexamic acid 1 gm IV was given 20 minutes before making incision for caesarean section and the control group of 50 did not receive tranexamic acid. Statistical Analysis: For quantitative outcomes, the t-test was used to test for difference in the two groups. For categorical outcomes, chi square and odds ratio with 95% confidence interval were used as applicable. Results: The patient characteristics, namely age, height, weight, gestational age and gravidity in two groups were similar which was statistically insignificant. Hemoglobin decreased slightly after birth in both groups but no statistical difference between two groups was noticed. There was no episode of thrombosis in the study. Tranexamic acid significantly reduced the quantity of the blood loss from time of placental delivery to 2 hours postpartum (P Conclusion: A safe dose of tranexamic acid has an effective role in reducing blood loss during LSCS without causing adverse reaction. Thus, drug can be used effectively in reducing maternal morbidity and mortality during LSCS.
