For an intradermal (ID) injection, you'll typically use a needle with a length of 1/4 inch to 1/2 inch and a gauge of 25-27. According to the provided reference, intradermal injections are administered into the dermis, just below the epidermis, using a tuberculin syringe.
Here's a breakdown:
- Needle Length: 1/4 to 1/2 inches
- Needle Gauge: 25-27
Why These Specific Sizes?
The specific needle size is crucial for ensuring the medication is delivered into the dermis.
-
Length: The short length (1/4 to 1/2 inch) ensures the needle doesn't go too deep into subcutaneous tissue.
-
Gauge: The smaller gauge (25-27) minimizes trauma to the skin and reduces the risk of bleeding.
