A vial of<unk>  sodium for injection<unk>  acts as an anticoagulant, preventing the formation of clots and extension of existing clots within the blood. While<unk>  itself does not break down clots that<unk> ave already formed (unlike tissue plasminogen activator), it allows the body's natural clot lysis mechanisms to work normally to break down clots that<unk> ave formed.<unk>  is generally used for anticoagulation for the following conditions: * Acute coronary syndrome, e.g., NSTEMI * Atrial fibrillation * Deep-vein thrombosis and pulmonary embolism * Cardiopulmonary bypass for<unk> eart surgery * ECMO circuit for extracorporeal life support *<unk> emofiltration * Indwelling central or peripheral venous catheters<unk>  and its low-molecular-weight derivatives (e.g., enoxaparin, dalteparin, tinzaparin) are effective in preventing deep vein thromboses and pulmonary emboli in people at risk, but no evidence indicates any one is more effective than the other in preventing mortality. In angiography, 2 to 5 units/mL of unfractionated<unk>  saline flush is used to prevent the clotting of blood in guidewires, sheaths, and catheters, thus preventing thrombus from dislodging from these devices into the circulatory system .
