Heparin sodium salt is widely used as an anticoagulant in medical settings. It is commonly administered to prevent and treat blood clots in conditions such as deep vein thrombosis, pulmonary embolism, and during surgeries like heart bypass procedures. In dialysis, it helps prevent clot formation in the dialysis machine and tubing. Additionally, it is used in blood transfusions and blood sample collection to maintain fluidity. Heparin sodium salt is also utilized in certain laboratory procedures to inhibit blood clotting in test samples. Its fast-acting properties make it a critical component in emergency and intensive care scenarios.
