    AbstractWe performed a randomized double-blind study on the effect of tranexamic acid on postoperative blood loss and blood transfusions in 39 primary THR operations. Tranexamic acid was given at the end of the operation and 3 hours later. Ultrasound examination 1 week later was performed to measure the occurrence of deep hematomas. In contrast to previous findings in knee arthroplasty, the administration of tranexamic acid failed to give a significant reduction in the postoperative blood loss. This lack of effect was possibly related to the fact that the drug was administered too late. In 11 of the 20 patients receiving tranexamic acid, blood transfusion was not necessary, this being the case in 4/19 in the placebo group (p = 0.05). The occurrence of postoperative deep venous thromboses was similar in the tranexamic acid and placebo groups.
