Article scientifique 2022 Anglais

Résumé

BACKGROUND: Objective to assess the value of preoperative tranexamic acid (TXA) in reduction of intraoperative and postoperative blood loss in high-risk cesarean delivery (CD). METHODS: A double blind randomized controlled trial included 160 high risk women who underwent elective lower segment CD. They were equally randomized to receive either 1 g of TXA or placebo 15 min before surgery. The primary outcome was Intraoperative blood loss. RESULTS: The estimated blood loss was significantly higher in the placebo group when compared to TXA group (896.81 ± 519.6 vs. 583.23 ± 379.62 ml, P < 0.001). Both postoperative hemoglobin and hematocrit were lower (9.2 ± 1.6 and 27.4 ± 4.1 vs. 10.1 ± 1.2 and 30.1 ± 3.4, P values < 0.001and 0.012 respectively) and their change percentages (15.41 vs. 7.11%, P < 0.001) were higher in the placebo group when compared to TXA one. The need for further ecbolics was higher in placebo group when compared to TXA group (46.25 vs. 13.75%, P < 0.001). CONCLUSION: Preoperative TXA is safe and effective in reducing blood loss during and after high-risk CD. TRIAL REGISTRATION: ClincalTrial.gov ID: NCT03820206 .
