The correct method is 100ml plus half a branch.

The concentration of the drug needs to depend on the specific environment.

The clinical application of heparin is generally intravenous injection or intramuscular injection: 05000 ~ 10000 units/time, 4 ~ 12 hours, 1 time.

Intravenous drip: 65,438+0 ~ 20,000 units are added to 5% glucose water or physiological saline, and drip once every 24 hours, with 20 ~ 50 drops per minute.

Heparin sodium injection is a low molecular weight heparin with high anti-ⅹ A (100 i.u./mg) activity and low anti-Ⅱ A or antithrombin (about 28I.U./mg) activity.

The dosage of heparin sodium injection required for different indications does not prolong the bleeding time.

Extended data

The use of heparin sodium:

1. Prevent thrombosis and embolism, such as deep vein thrombosis, myocardial infarction, pulmonary embolism, thrombophlebitis and postoperative thrombosis.

2. Treat disseminated intravascular coagulation (DIC) caused by various reasons, such as bacterial septicemia, early placental abruption and cytolysis of malignant tumor, except for DIC caused by snake bite.

Early application can prevent the consumption of fibrinogen and other coagulation factors.

3. Other anticoagulants in vivo and in vitro, such as cardiac catheterization, cardiopulmonary bypass in heart surgery, hemodialysis, etc.
