Effectiveness of Tranexamic Acid in Reducing Blood Loss During Femoral Nail Surgery

Overview

This clinical study aims to evaluate the safety and effectiveness of administering a single intravenous dose of tranexamic acid (TXA) before surgery to reduce blood loss in patients undergoing open intramedullary nailing for femoral shaft fractures. In many resource-limited settings, including Uganda, this surgical approach is common due to lack of fluoroscopic equipment, and it is known to be associated with significant perioperative blood loss. Tranexamic acid is an antifibrinolytic agent that helps stabilize blood clots and is widely used to reduce bleeding in major surgeries such as joint replacements and spinal procedures. However, its role in trauma-related open femoral surgeries in low-resource settings remains underexplored. This study investigates whether preoperative intravenous TXA can safely reduce blood loss and transfusion needs during and after surgery in patients with isolated femoral shaft fractures managed at Mulago National Referral Hospital.

This is a prospective, open-label, single-arm cohort study designed to assess the safety and effectiveness of preoperative intravenous tranexamic acid (TXA) in adult patients undergoing open intramedullary nailing for femoral shaft fractures in a resource-limited hospital setting. The study enrolled 43 adult participants with isolated, closed femoral shaft fractures scheduled for surgical fixation at Mulago National Referral Hospital. Each participant received a single dose of intravenous tranexamic acid (15 mg/kg), administered over 10 minutes approximately 10 minutes prior to skin incision. The dose was prepared and delivered by the anesthetist in the operating theatre. The primary objective of the study is to estimate perioperative blood loss, assessed by comparing preoperative hemoglobin concentration (taken 2 hours before surgery) to postoperative hemoglobin (taken 72 hours after surgery). Secondary objectives include assessing the proportion of patients requiring blood transfusions and documenting any adverse events associated with TXA administration, such as hypotension, nausea, or allergic reactions. Surgical procedures were performed using either antegrade or retrograde open intramedullary nailing techniques. Standard perioperative care was provided, including preoperative antibiotics and either spinal or general anesthesia. All blood draws were conducted under aseptic conditions. Transfusion decisions followed standard clinical protocols based on clinical signs and hemoglobin thresholds. This study is intended to inform clinical practice in low-resource settings by providing data on the potential utility of tranexamic acid in orthopedic trauma surgery where blood conservation is especially critical.
