Article Abstract
Purpose: To evaluate the effect of intraoperative tranexamic acid (TXA) on perioperative blood loss, transfusion requirements, and clinical outcomes in patients undergoing proximal femoral nailing (PFN) for intertrochanteric fractures.
Methods: A retrospective cohort study of 1,728 patients who underwent PFN fixation for intertrochanteric fractures between 2017 and 2024. Perioperative hemoglobin (Hb) dynamics, transfusion requirements, and clinical outcomes were compared between patients receiving 1-1.5 g intravenous TXA (n = 1,446) and controls (n = 282).
Results: The TXA group demonstrated reduced perioperative Hb decline (2.15 ± 1.40 vs 2.76 ± 1.57 g/dL, p < 0.001) and lower rates of Hb drop > 2 g/dL (47.9% vs 63.5%, OR 0.53, p < 0.001). TXA administration was associated with decreased transfusion requirements (7.1% vs 11.0%, p = 0.021). Multivariate analysis confirmed TXA as an independent protective factor against blood loss. Mortality rates showed no significant difference between groups.
Conclusion: Intraoperative TXA during PFN fixation was associated with reduced perioperative blood loss and transfusion requirements. These findings support TXA as an effective blood conservation strategy in elderly patients with intertrochanteric fractures.

Epiphany Dermatology, Dallas, Texas.
Background: Bleeding remains a frequent complication during Mohs micrographic surgery, particularly among patients receiving anticoagulant or antiplatelet therapy. The growing use of these medications has prompted increased exploration of adjunctive methods to improve perioperative hemostasis.
Objective: To systematically review the literature on topically and locally administered hemostatic agents used to reduce bleeding in Mohs micrographic surgery.

Use of Tranexamic Acid Reduces Opioid Consumption After Arthroscopic Rotator Cuff Repair.
J Shoulder Elbow Surg
September 2025
Keck School of Medicine of USC, University of Southern California, Los Angeles, California.
Background: Tranexamic acid (TXA) is an anti-fibrinolytic agent that has effectively reduced transfusion risk and minimized blood loss after total joint arthroplasty. TXA use has had mixed results on postoperative pain after arthroscopic rotator cuff repair (ARCR). The purpose of this prospective, double-blind, randomized, controlled trial was to examine the impact of TXA on prescription opioid consumption for three postoperative days in an outpatient population after ARCR.
