What are two key things to do when administering local anesthetic?

• A. Aspiration & slow deposition
• B. Use of vasoconstrictor alone
• C. Rapid deposition
• D. No needle aspiration

Answer: (A)

The essential safety practices when giving local anesthetic are preventing intravascular injection and controlling how the drug is delivered. Aspiration means pulling back on the syringe plunger after you place the needle to check for blood. If blood appears, the needle is in or near a vessel, so you reposition and recheck before injecting. This step minimizes the risk of injecting a large amount of anesthetic directly into the bloodstream, which can cause serious toxicity. Depositing the anesthetic slowly is the other key step. By delivering small amounts over a period of time, you avoid a rapid rise in the drug’s plasma level, promote better diffusion into the tissues, and give yourself a chance to detect any early adverse signs. Rapid deposition can lead to sudden high plasma concentrations and less predictable anesthesia. Using a vasoconstrictor can help with prolonged effect and reduced bleeding, but it does not replace the need for aspiration or slow deposition. No-aspiration injections ignore a critical safety check and significantly raise the risk of intravascular administration, which is why that option is not appropriate.
