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
Yes, the dorsogluteal site of injection is associated with a higher risk of skin and tissue trauma, muscle fibrosis or contracture, haematoma, nerve palsy, paralysis, and infections such as abscesses and gangrene. Injections into the deltoid site in the arm can result in unintentional damage to the radial and axillary nerves include pain, redness, and inflammation around the injection site, which are almost always mild and last only a few days at most. The dorsogluteal site of injection causes skin and tissue trauma, muscle fibrosis or contracture, haematoma, nerve palsy, paralysis, abscesses and gangrene. Injection in the gluteal muscle cause damage to the sciatic nerve, Yes - there is a risk of infection from bacteria or other organisms present in the environment or on the skin prior to the injection.

Injections into the deltoid site in the arm can result in unintentional damage to the radial and axillary nerves. In rare cases when not performed properly, the injection may result in shoulder dysfunction. 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.

The dorsogluteal site of injection is associated with a higher risk of skin and tissue trauma, muscle fibrosis or contracture, haematoma, nerve palsy, paralysis, and infections such as abscesses and gangrene. Furthermore, injection in the gluteal muscle poses a risk for damage to the sciatic nerve, which may cause shooting pain or a sensation of burning. Sciatic nerve damage can also affect a person's ability to move their foot on the affected side, and other parts of the body controlled by the nerve. Damage to the sciatic nerve can be prevented by using the ventrogluteal site instead, and by select As with any injection which pierces the skin, there is a risk of infection from bacteria or other organisms present in the environment or on the skin prior to the injection.
