Intracutaneous injection
As intracutaneous injection (from latin intra =, in ' cutis = skin'; inicere infuse Abbr. I c, too.. Intracutaneously written) or intradermal injection refers to the injection of a liquid medicament into the dermis (dermis). The dermis is located below the epidermis and above the subcutis . Thus, intracutaneous injection must be differentiated from epicutaneous and subcutaneous injection.
indication
The intracutaneous injection is mainly used for allergy tests and the tuberculin test ( Mendel-Mantoux test ), since there are more defense cells (especially dendritic cells ) in the dermis than in the subcutaneous and intramuscular area.
It enables the treatment of hyperhidrosis , in which botulinum toxin is initiated intracutaneously.
Intracutaneous injection is also used to place a wheal in neural therapy and mesotherapy .
Injection technique
After applying a disinfectant solution and allowing it to take effect for at least 30 seconds, a fine cannula is used to puncture the skin almost parallel to the surface of the skin. The formation of a wheal and the lightening of the skin at the injection site indicate a correct intracutaneous injection.
Lancets or vaccination pistols can also be used for intracutaneous vaccination .
