WHAT routes of parenteral medication administration require that aspiration be performed prior to injection of the medication EXCEPT?

Aspiration prior to injection is typically required for intramuscular (IM) injections and some subcutaneous (SC) injections, particularly in areas near major blood vessels. However, aspiration is generally not necessary for intradermal (ID) injections, intravenous (IV) injections, or when administering certain vaccines. The purpose of aspiration is to ensure that a blood vessel has not been inadvertently punctured, minimizing the risk of complications.
