Local tranexamic acid reduces surgical blood loss
Abstract
Tranexamic acid (TXA) is a synthetic lysine analog that reduces perioperative blood loss by blocking lysine-binding sites on plasminogen molecules. It has been reported to be effective in limiting blood loss and transfusion needs in various orthopedic surgeries and for pediatric patients at high risk of blood loss. Randomized controlled trials (RCTs) supporting the capacity of TXA to reduce blood loss and improve outcomes associated with various surgical procedures have increased fourfold in the 10 years since Evidence Corner addressed this topic, which highlighted the capacity of locally delivered TXA to reduce blood loss during orthopedic knee surgery and intravenously delivered TXA to reduce blood lost during elective cesarean sections. Research continues to explore whether the ideal method of TXA delivery is local or systemic. One systemic preoperative 10 mg/kg dose of TXA did not improve blood loss, wound healing, or pain-related outcomes associated with ambulatory foot and ankle surgery. However, repeated topical doses of TXA as well as combined systemic and topical doses improved blood loss, inflammation, and nutritional condition following hip arthroplasty. This installment of Evidence Corner reviews 2 recent studies exploring the effects of adding locally delivered TXA to intravenous (IV) systemic TXA during spinal surgery8 and confirming efficacy of a single dose of topical TXA on hip arthroplasty.
