Abstract

Study Design: Nonrandomized, prospective, and case-controlled study. Purpose: To evaluate the efficacy and cost-effectiveness of topically applied tranexamic acid (TXA) during different phases of spine surgery. Overview of Literature: Perioperative blood loss is the leading cause of postoperative anemia associated with prolonged stays in hospital and long recovery times. The direct and indirect costs involved pose a significant economic challenge in developing countries. There is no consensus for topical use of tranexamic acid in spine surgery.
Methods
Patients requiring a single-level TLIF were divided into two groups. In the TXA group (n=75), the wound surface was soaked with TXA (1 g in 100 mL saline solution) for 3 minutes after exposure, after decompression, and before wound closure, and in the control group (n=175) using only saline. Intraoperative blood loss drain volume was recorded on each of the first 2 days immediately after surgery. An estimated cost analysis was made on the basis of the length of hospital stay and the blood transfusion.
Results
IBL for the control group was 783.33±332.71 mL and for intervention group 410.57±189.72 mL (p <0.001). The operative time for control group was 3.24±0.38 hours and for intervention group 2.99±0.79 hours (p <0.695). Hemovac drainage on days 1 and 2 for control group was 167.10±53.83 mL and 99.33±37.5 mL, respectively, and for intervention group 107.03±44.37 mL and 53.38±21.99 mL, respectively (p <0.001). The length of stay was significantly shorter in the intervention group (4.8±1.1 days) compared to control group (7.0±2.3 days). The cost of treatment in the intervention group was US dollar (USD) 4,552.57±1,222.6 compared with that in the control group USD 6,529.9±1,505.04.
Conclusions
Topical TXA is a viable, cost-effective method of decreasing perioperative blood loss in major spine surgery with fewer overall complications than other methods. Further studies are required to find the ideal dosage and timing.
