What type of bevel is used for intradermal injections?

Intradermal injections require a short bevel needle to ensure that the medication is deposited just beneath the surface of the skin without penetrating too deeply. A short bevel allows for a more controlled and precise needle insertion, which is crucial in this type of injection as it targets the dermis – the layer of skin just below the epidermis.

Using a short bevel minimizes the risk of the needle going too deep, which could lead to subcutaneous injection or even intramuscular injection, neither of which would achieve the desired effect of an intradermal injection. This technique is commonly used for allergy tests and tuberculosis screening, where a localized response at the injection site is necessary for accurate assessment.

The other bevel types, such as long bevel, double bevel, and flat bevel, are more suitable for other types of injections or procedures, focusing on either deep tissue penetration, greater fluid delivery speed, or different angles of entry, which are not appropriate for intradermal injections.
