The use of tranexamic acid in spine surgery
Patients undergoing surgical procedures of the spine with associated large volume blood loss often require perioperative blood conservation strategies. Synthetic antifibrinolytic medications such as tranexamic acid (TXA) may reduce blood transfusion requirements and postoperative complications following spinal procedures. Studies investigating the role of TXA in spine surgery have presented promising results and have proven its safety and efficacy. However, further investigation is needed to determine the optimal dosing regimen of TXA. In this article, we provide an overview of the basic science and pharmacology of TXA. A comprehensive summary of the findings from clinical trials and a review of the literature that demonstrate the risks and benefits of TXA in spine surgery are also presented.
