Xu D, et al. - In this study, gelatin sponge, collagen sponge, and topical application of tranexamic acid (TXA) were assessed as hemostatic options for blood loss following posterior spinal fusion surgeries. Findings demonstrated that in patients undergoing posterior spinal fusion surgeries, collagen and topically applied TXA displayed efficacy as well as safety, while TXA showed better efficacy. Researchers also observed a significant reduction in the total amount of perioperative blood loss, with no increment in the incidence of related complications.
