Tranexamic Acid Use to Reduce Blood Transfusion in Pediatric Cancer Patients Undergoing Limb Salvage Procedure

Eligible participants undergoing limb salvage procedures will be randomized to receive either tranexamic acid (TXA) or placebo peri-operatively. The initial dose of tranexamic acid/placebo will be given at the initiation of surgical preparation. The second dose will be given 6 hours after the first dose (either intraoperatively or post-operatively). All doses will be given intravenously. Doses will be double blinded and randomized for each surgical procedure.
