About the study

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 different method of delivery like intravenous (IV) TXA reduces the postoperative reduction in hemoglobin, hematocrit, number of transfusions, and postoperative blood loss following open spine surgery. The regimen that utilizes multiple doses of oral TXA will significantly minimize post-operative blood loss and transfusion requirements compared to the use of a single dose regimen. Furthermore, oral TXA will be as efficacious as intravenous delivery of TXA.
