Erythropoietin subcutaneous injection methods and sites

Erythropoietin can be administered via subcutaneous injection or intravenous infusion. The subcutaneous erythropoietin injection comes in a pre-filled syringe. Injection sites are typically areas of skin with rich blood circulation, such as the skin near the deltoid muscle of the upper arm or around the abdomen near the navel. The procedure should be performed by a trained professional, and the specific steps are as follows:

1. Check the production date and specifications on the erythropoietin packaging to ensure the medication is within its expiration date and the correct dosage strength. Tear open the protective film along the designated tear line and remove the prefilled syringe.

2. After drawing up the medication, slightly tilt the needle upward and slowly push the syringe plunger to expel air until a drop of solution appears at the needle tip.

3. Select the injection site and disinfect the area using an alcohol swab, wiping in a circular motion starting from the intended injection point. The disinfected area should have a diameter of at least 5 cm.

4. With one hand, gently pinch the skin at the injection site; with the other hand, insert the needle perpendicularly into the skin. Push the plunger to inject the medication into the subcutaneous tissue.

5. After completing the injection, withdraw the needle at the same angle used for insertion, then apply pressure to the puncture site with a cotton ball or swab to stop any bleeding. Patients receiving subcutaneous erythropoietin injections must strictly follow their doctor's instructions. The physician will determine the appropriate injection frequency and dosage. Additionally, patients need regular follow-up visits to the hospital to evaluate treatment effectiveness.
