1. Wash your hands.
2. Reassure the patient and explain the procedure.
3. Uncover arm completely.
4. Have the patient relax and support his arm below the vein to be used.
5. Apply tourniquet and look for a suitable vein.
6. Wait for the vein to swell.
7. Disinfect skin.
8. Stabilize the vein by pulling the skin taut in the longitudinal direction of the vein. Do this with the hand you are not going to use for inserting the needle.
9. Insert the needle at an angle of around 35 degrees.
10. Puncture the skin and move the needle slightly into the vein (3-5 mm).
11. Hold the syringe and needle steady.
12. Aspirate. If blood appears hold the syringe steady, you are in the vein. If it does not come, try again.
13. Loosen tourniquet.
14. Inject (very) slowly. Check for pain, swelling, hematoma; if in doubt whether you are still in the vein aspirate again!
15. Withdraw needle swiftly. Press sterile cotton wool onto the opening. Secure with adhesive tape.
16. Check the patient's reactions and give additional reassurance, if necessary.
17. Clean up; dispose of waste safely; wash your hands.
