Heparin Sodium Subcutaneous Injection Methods and Sites

Heparin sodium is primarily used to treat or prevent venous thrombosis. It is generally administered in a formal medical setting, with subcutaneous injections given under the guidance of a qualified physician, typically in the abdominal area. The specific procedure is as follows:

1. First, the doctor evaluates the patient's condition and treatment plan to determine whether the patient can tolerate subcutaneous injection.

2. The patient should lie flat and the injection site—usually the anterior-lateral or posterior-lateral abdominal wall—should be identified.

3. The doctor disinfects the injection site with alcohol or iodophor to prevent infection.

4. The doctor draws up heparin sodium into a syringe and expels all air from the syringe.

5. The doctor pinches the skin at the injection site with the thumb and index finger, inserts the needle perpendicularly into the skin fold, fully advancing the needle into the fold. After completing the injection, the needle is withdrawn.

6. Finally, apply gentle pressure with a dry cotton swab for several minutes to stop bleeding.
