This is a randomized, single-blind, single-center study comparing calculated total blood
loss, surgical drain output and hematoma formation in anticoagulated patients who receive 2
doses of Tranexamic Acid (TXA) versus control group undergoing anatomical and reverse total
shoulder arthroplasty. Patients will be randomized to either receive 2 doses of IV TXA, first
dose prior to surgical incision and second dose given 3 hours later or to the control group,
where no TXA will be administered.
