Heparin sodium is a sodium salt of glucan aminosulfate extracted from pig intestinal mucosa, which can be effective in many important links in the process of blood coagulation system. It has anticoagulation effect in vivo and in vitro, and is mainly used for in vitro anticoagulation, treatment or prevention and treatment of thrombosis.

　　Notes for medication introduced by heparin manufacturers:

　　Heparin sodium needs to be used in sufficient amount and in sufficient stages. Do not arbitrarily reduce the amount and stop the medication, otherwise it will affect the effect.

　　Heparin sodium injection does not respond to oral treatment and can be administered intravenously or intravenously, as well as by means of influencing subcutaneous injection. Subcutaneous injection should deepen the fat layer, if repeated injection, injection site should be replaced. Do not move the needle when injecting, do not rub the injection site, and avoid injecting the drug with other drugs.

　　Coagulation should be monitored strictly during medication, especially in patients with liver and kidney insufficiency.

　　For those with a sensitive constitution, medication should be tested first. If there is no special reaction, you can continue to take the medication.

　　Heparin sodium can interfere with the determination of prothrombin time and time. If the determination is needed, the test should be repeated 4 hours after the use of heparin sodium.

　　If heparin sodium is less effective because the antithrombin disk in the plasma is down, plasma or antithrombin I can be injected.

　　Heparin sodium metabolism is agile, if excessive use of heparin sodium, then timely withdrawal can be used, such as severe excessive, use fish sulfate sperm protein slow intravenous neutralization.
