What is the #1 danger when using the dorsogluteal site for IM injection?

The primary danger of using the dorsogluteal site for intramuscular (IM) injections is the potential for damage to the sciatic nerve. This site is located in the upper outer quadrant of the buttock, which is near the path of the sciatic nerve. If the injection is not performed correctly, or if the needle is inserted at the wrong angle or depth, it could result in hitting the sciatic nerve. This can lead to severe complications, including nerve damage or pain.

The anatomical proximity of the sciatic nerve to the injection site makes this risk particularly high, which is why many healthcare professionals are encouraged to use alternative sites for IM injections, such as the ventrogluteal site. Understanding the anatomy and the risks associated with each injection site helps practitioners to minimize complications and ensure patient safety.
