Remember from anatomy that the skin is made up of the outer layer, called the epidermis. The second layer of skin is the dermis. The connective tissue under the dermis is called the subcutaneous tissue. This is where subcutaneous injections are given. The abdomen is a good site for subcutaneous injections because this is an area that has a lot of subcutaneous tissue. Using a needle 1/2 inch longer than a person's thumb is not an evidence-based method for measuring needle length needed for subcutaneous injection. The deltoid is a muscle, not a subcutaneous site. Disposing of needles and syringes into a garbage can creates a biomedical hazard and therefore is not appropriate.
