High-dose continuous infusion of tranexamic acid for controlling life-threatening bleed in advanced cancer patients

Abstract

Life-threatening bleeding although uncommon in palliative care is associated with significant distress among patients and family. The current guidelines emphasize the need for identification of a patient with early signs of bleeding and providing assurance and comfort care to patients and family in case of an event. There is very little known about the role of high dose of tranexamic acid, a lysine analog in controlling the bleeding irrespective of the underlying pathophysiology of the bleed. Tranexamic acid is known to competitively block the lysine-binding site of plasminogen and thus inhibit the activation of plasminogen to plasmin and at high-concentration tranexamic acid noncompetitively blocks plasmin, thus inhibiting the dissolution and degradation of fibrin clots by plasmin. Here, we discuss two case studies of patients who presented with massive bleed from the tumor site. With a high dose of continuous intravenous infusion of tranexamic acid, there was a complete arrest of the bleed with a reduction in the requirement for blood transfusion.
