    ObjectivesTo determine the efficacy of intraoperative treatment with low dose tranexamic acid in reducing the rate of perioperative transfusions in patients undergoing radical retropubic prostatectomy.DesignDouble blind, parallel group, randomised, placebo controlled trial.SettingOne university hospital in Milan, Italy.Participants200 patients older than 18 years and undergoing radical retropubic prostatectomy agreed to participate in the trial. Exclusion criteria were atrial fibrillation, coronary artery disease treated with drug eluting stent, severe chronic renal failure, congenital or acquired thrombophilia, and known or suspected allergy to tranexamic acid.InterventionsIntravenous infusion of tranexamic acid or equivalent volume of placebo (saline) according to the following protocol: loading dose of 500 mg tranexamic acid 20 minutes before surgery followed by continuous infusion of tranexamic acid at 250 mg/h during surgery.Main Outcome MeasuresPrimary Outcomenumber of patients receiving blood transfusions perioperatively. Secondary outcome: intraoperative blood loss. Six month follow-up to assess long term safety in terms of mortality and thromboembolic events.ResultsAll patients completed treatment and none was lost to follow-up. Patients transfused were 34 (34%) in the tranexamic acid group and 55 (55%) in the control group (absolute reduction in transfusion rate 21% (95% CI 7% to 34%); relative risk of receiving transfusions for patients treated with tranexamic acid 0.62 (0.45 to 0.85); number needed to treat 5 (3 to 14); P = 0.004). At follow-up, no patients died and the occurrence of thromboembolic events did not differ between the two groups.ConclusionsIntraoperative treatment with low dose tranexamic acid is safe and effective in reducing the rate of perioperative blood transfusions in patients undergoing radical retropubic prostatectomy.
