Objective: To compare topical intravenous tranexamic acid (TA) in total knee arthroplasty regarding blood loss and transfusion.
Methods: Ninety patients were randomized to receive TA intravenously (20 mg/kg in 100 mL of saline; group IV), topically (1.5 g in 50 mL of saline, sprayed over the operated site, before release of the tourniquet; topical group), or intravenous saline (100 mL with anesthesia; control group).
Background: Tranexamic acid (TXA) is widely used in orthopedic surgery to reduce perioperative bleeding. Since TXA inhibits fibrinolysis, there is concern that it may increase the risk of thromboembolic events.
Objectives: To verify the prevalence of deep venous thrombosis (DVT) in patients receiving TXA during total knee arthroplasty and to compare topical with intravenous administration of the drug.
