As tranexamic acid (TXA) becomes more prevalent, all patients are receiving the same dose and
method of delivery regardless of their pre-operative risk of transfusion. Therefore, the aim
of the study is to determine whether or not repeated dosing of oral or a different method of
delivery like intravenous (IV) TXA reduces the post-operative reduction in hemoglobin,
hematocrit, number of transfusions, and postoperative blood loss following open spine
surgery.
