Intradermal injection needle operation method

1. Bring all the supplies to the bedside, check and explain to the patient in order to obtain cooperation. Before doing the skin test, you should ask about the history of allergies in detail. If you have a history of allergies to the liquid that needs to be injected, you cannot do the skin test. You should get in touch with your doctor and try again after changing other drugs.

2. Use a 1ml syringe and needle to draw out the liquid and exhaust the air.

  3. Choose the palm side of the forearm (or the lower edge of the deltoid muscle), disinfect the skin with a 70% alcohol swab to dry, tighten the skin with the left hand, hold the syringe in the right hand, make the needle oblique face up, and pierce the skin into the skin at 5 to 15 degrees ( Figure 10-5).

  4. After the bevel of the needle enters the skin, flatten the syringe and inject 0.1ml of the liquid medicine. The amount of medicine must be accurate, so that a round raised skin is formed locally, the skin becomes white and the pores become larger.

5. After the injection, quickly pull out the needle, do not rub it, clean up the material, and observe the reaction on time.

6. For a control test, use another syringe and needle to inject 0.1ml of isotonic saline on the same part of the other forearm for 20 minutes, and then observe the reaction.
