Brief Summary:
Hypothesis: Topical application of Tranexamic acid into the surgical wound during spine surgery will decrease the overall blood loss post-operatively. This reduction in blood loss will reduce the need for transfusion. In addition it will also significantly reduce the cost of the surgical procedure.
Specific Aim 1: The goal of this study is to quantitatively assess whether topical application of tranexamic acid placed into the surgical wound during lumbar spine surgery will decrease post-operative blood loss, thus lowering the need for blood transfusions. By reducing the number of transfusions participants can avoid the well-known complications associated with them. The investigators do not plan on measuring serum tranexamic acid levels.
Several meta-analyses and level I studies have shown that intravenous (IV) administration of tranexamic acid is effective in reducing postoperative blood loss and the need for transfusion.
Detailed Description:
Tranexamic acid, an antifibrinolytic agent, has been studied at great length across a myriad of medical specialties to reduce blood lost during these surgeries. Topical tranexamic acid administration reduces postoperative blood loss and proved safe in multiple types of surgeries -e.g. cardiothoracic, oral and maxillofacial, eye, ear and throat.(References: Fawzy and others \[et al\], Wong et al, Zufferey et al, Wang et al, Ipema et al).
Intravenous tranexamic acid administration has been shown to reduce postoperative blood loss and transfusion need in patients undergoing spinal surgery (Reference: Elwatidy et al). Some advocates have suggested that topical (i.e. local) administration might be preferred over intravenous application. Topical administration of tranexamic acid has some potential advantages as it leads to lower systemic absorption, and offers less concern over the risk of thromboembolic complications (References: Wong et al, Raveendran et al).
While systemic (intravenous) use of tranexamic acid has been studied in spine surgery, there has been little studied to show its effectiveness at reducing blood loss when used topically.
This study proposes to determine if the topical application of tranexamic acid into the surgical wound of posterior multi-level lumbar spine surgery will decrease postoperative blood loss, thus decreasing the need for potential transfusions. Tranexamic acid has been well documented for its safety and efficacy, the investigators believe that this agent will become an important tool to reduce the blood loss in spinal surgeries. It offers a reduction in blood loss and, ultimately, a decrease in the transfusion rates which pose risks to the subject and significant cost.
