PURPOSE

This study aimed to assess the effects of topical tranexamic acid (tTXA) in spinal surgery to provide reliable clinical evidence for its usefulness.

METHODS

The PubMed, EMBASE, Medline, and Cochrane Central Register of Controlled Trials databases were comprehensively searched to identify randomized controlled trials and non-randomized controlled trials evaluating the effect of tTXA on blood loss during spine surgery. The observation indexes were intraoperative blood loss, total blood loss, output and duration of postoperative drainage, postoperative hematological variables, length of postoperative hospital stay, blood transfusion rate, and complication rate.

RESULTS

A total of 21 studies involving 1774 patients were included. Our results showed that the use of tTXA during spinal surgery significantly reduced the total blood loss, postoperative drainage volume, postoperative transfusion rate, duration of postoperative drainage, and postoperative hospital stay, and increased the serum hemoglobin concentration, thereby providing better clinical outcomes for surgical patients. However, tTXA had no effect on intraoperative blood loss and associated complications.

CONCLUSION

On the basis of the available evidence, the present results provide strong clinical evidence of the clinical value of tTXA in spinal surgery and provide an important reference for future research and clinical decision-making.
