Objectives

Narrative objectives1

Tranexamic acid (TXA) has been used to reduce perioperative bleeding in various surgery because of its antifibrinolytic effect. Recently, the patients undergoing orthopedic surgery in our hospital received a loading dose of TXA (1000 mg) before surgery followed by 100 mg/hour until the end of surgery. The purpose of this retrospective study is to evaluate the efficacy of TXA administration on the perioperative blood loss in patients undergoing knee arthroplasty or hip arthroplasty.

Results

A total of 135 patients were included during the study period. 63 patients for the control group and 72 patients for the TXA group. The demographic data were similar between the two groups. The intraoperative infusion, the postoperative transfusion, delta Hb, and estimated blood loss were significantly reduced in the TXA group, although there were no significant differences in the volumes of intraoperative transfusion and blood loss.
