Tranexamic Acid and Vitamin K Administration in Bleeding Patients

Tranexamic Acid Administration

• The recommended dosage of TXA for bleeding patients is 1g administered intravenously over 10 minutes, followed by an infusion of 1g over 8 hours 1
• TXA should be administered as soon as possible after significant bleeding is identified, ideally within 3 hours of injury onset for maximum efficacy 2

Vitamin K Administration

• Vitamin K can be administered both intramuscularly (IM) and intravenously (IV) 3
• IV administration is preferred in urgent situations requiring rapid reversal of anticoagulation 3
• For patients on oral vitamin K antagonists (VKAs) with major bleeding or requiring urgent procedures, the recommended reversal protocol includes intravenous four-factor prothrombin complex concentrates (4F-PCCs) and 5 mg intravenous vitamin K 3

Precautions and Monitoring

• Monitor for potential adverse effects of TXA, such as thromboembolic events, especially in elderly patients 2
• Evaluate clinical response through decreased bleeding and stabilization of hemoglobin levels 2
• Monitor coagulation parameters, especially in patients with massive bleeding 2

Special Considerations

• Carefully evaluate implementing permissive hypotension in managing selected elderly trauma patients 3
• Tissue perfusion should be constantly monitored by base excess level, arterial lactates, urine output, and neurologic assessment 3
