ObjectiveTo study the efficacy and safety of preoperative intravenous tranexamic acid to reduce blood loss during and after elective lower-segment cesarean delivery.MethodsA single-blind, randomized placebo-controlled study was undertaken of women undergoing elective lower-segment cesarean delivery of a full-term singleton pregnancy at a center in Cairo, Egypt, between November 2013 and November 2014. Patients were randomly assigned (1:1) using computer-generated random numbers to receive either 1g tranexamic acid or 5% glucose 15 minutes before surgery. Preoperative and postoperative complete blood count, hematocrit values, and maternal weight were used to calculate the estimated blood loss (EBL) during cesarean, which was the primary outcome. Analyses included women who received their assigned treatment, whose surgery was 90 minutes or less, and who completed follow-up.ResultsAnalyses included 100 women in each group. Mean EBL was significantly higher in the placebo group (700.3 ± 143.9 mL) than in the tranexamic acid group (459.4 ±7 5.4 mL; P<0.001). Only six women, all in the placebo group, experienced an EBL of more than 1000 mL. There were no reports of thromboembolic events up to 4 weeks postoperatively.ConclusionPreoperative administration of tranexamic acid safely reduces blood loss during elective lower-segment cesarean delivery.
