Abstract
BACKGROUND: This study aimed to evaluate the efficiency of constant dose intravenous administration of tranexamic acid (TXA) in reducing postoperative blood loss, hemoglobin (Hb) concentration, and the number of transfusions in revision hip arthroplasty (RHA). METHODS: The study included 145 consecutive patients who had undergone RHA: a TXA group (75 patients) who received two doses of TXA (1.0 g 15 min before skin incision and 1.0 g during wound closure) and a no-TXA group (70 patients). Percentage blood loss and quantitative blood loss were calculated. RESULTS: The percentage blood loss (23.82 ± 10.6% vs. 39.17 ± 15.1%; P < 0.001), Hb drop (2.9 ± 1.14 g/dL vs. 4.22 ± 1.4 g/dL; P < 0.001), and total blood loss (1030 ± 477 mL vs. 1736 ± 761 mL; P < 0.001) were significantly lower in the TXA group than in the no-TXA group on postoperative day 1. Percentage blood loss (37.5 ± 10.4% vs. 43.1 ± 12.5%; P < 0.01), Hb drop (4.64 ± 1.5 g/dL vs. 5.22 ± 1.6 g/dL; P < 0.01) and total blood loss (1639 ± 543 mL vs. 1908 ± 681 mL; P = 0.02) were significantly lower in the TXA group than in the no-TXA group on the 5th postoperative day. The blood transfusion requirements were lower in the TXA group than those in the no-TXA group (30.7% vs. 71.4% of patients; P < 0.001), with a lower transfusion per patient ratio of 0.55 in the TXA group and 1.4 in the no-TXA group. No postoperative complications were associated with TXA administration, including deep-vein thrombosis and pulmonary embolism. CONCLUSION: Administration of TXA is an effective method to reduce perioperative blood loss, Hb drop and the number of transfusions in RHA.
