Heparin sodium is crude heparin sodium extracted from the mucosa of the small intestine of healthy pigs. Because it contains a large amount of protein, nucleic acid, microorganism and other impurities, it needs physical and chemical extraction and separation process to get heparin with complete structure, and then make heparin raw material. While heparin sodium in vivo or in vitro, has a rapid anticoagulant effect, mainly on the formation of fibrin, but also can reduce platelet aggregation.
Indications for heparin sodium:
1. Prevent thrombosis and embolism, such as deep venous thrombosis, myocardial infarction, pulmonary embolism, thrombophlebitis and postoperative thrombosis, etc.
2. Treatment of DIC caused by various causes, such as bacterial sepsis, early placental dissection, and lysis of malignant tumor cells, except for DIC caused by snake bite. Early application prevents the depletion of fibrinogen and other clotting factors.
3. Other anticoagulants in vivo and in vitro, such as cardiac catheterization, cardiopulmonary bypass, hemodialysis, etc.
