Describe the vastus lateralis site used for injections.

Understand the Problem

The image provides information about the vastus lateralis site used for injections. It outlines several key points, including its recommendation when the ventrogluteal site is unsuitable, its location covering the anterolateral aspect of the thigh, the method of dividing the thigh into thirds, and its suitability for infants and children with poorly developed gluteal muscles.

Answer

The vastus lateralis site is on the anterolateral thigh, in the outer middle third, suitable for infants/children when ventrogluteal site is not an option.

The vastus lateralis site is located on the anterolateral aspect of the thigh. The thigh is divided into thirds, and the injection is given in the outer middle third. It is recommended when the ventrogluteal site cannot be used, and it is especially suitable for infants and children with poorly developed gluteal muscles.

More Information

The vastus lateralis is a safe and effective site for intramuscular injections because it is a large muscle that is relatively free of major blood vessels and nerves. It is also easily accessible, making it a convenient site for both patients and healthcare providers.

Tips

A common mistake is not identifying the correct landmarks for the injection site. Failure to administer the injection in the outer middle third of the vastus lateralis muscle could increase the risk of pain, nerve damage, or other complications.
