is it meant for any specific populations?
In some populations, a change in injection site, needle length, or technique is necessary; for  example, in very young people or frail elderly people, a normal length needle may be too long to safely inject in the desired muscle

the three most commonly used sites for intramuscular injections are The deltoid muscle of the upper arm, the gluteal muscle of the buttock, in infants, the vastus lateralis muscle of the thigh does this have any complications? Yes, the most frequent complications of a deltoid injection include pain, redness, and inflammation around the injection site, which are almost always mild and last only a few days at most. why is it taken? In medicine, it is one of several methods for parenteral administration of medications.
For example, in very young people or frail elderly people, a normal length needle may be too long to safely inject in the desired muscle. For this reason, in these people, a shorter needle is recommended to decrease the risk of injecting too deep.

To help infants and children cooperate with injection administration, the Advisory Committee on Immunization Practices in the United States recommends using distractions, giving something sweet, and slow lateral swaying. In people who are overweight, a 1.5-inch needle may be used to ensure the injection is given below the subcutaneous layer of skin, while a -inch needle may be used for people who weigh under . In any case, the skin does not need to be pinched up prior to injecting when the appropriate length needle is used.
