What are the potential complications of local anesthesia?

The potential complications of local anesthesia include a variety of adverse effects that may arise during or after the procedure. Paresthesia refers to abnormal sensations such as tingling or numbness, which can occur if the nerve is irritated or traumatized during injection. Hematoma, or localized bleeding outside of blood vessels, can form at the injection site due to punctured blood vessels. Allergic reactions can range from mild to severe and may occur as a result of the anesthetic agent or other substances in the anesthetic solution. Systemic toxicity happens when local anesthetic agents enter the bloodstream, potentially leading to serious cardiovascular or central nervous system effects.

This set of complications comprehensively encompasses both immediate and delayed adverse effects that practitioners must be aware of when administering local anesthesia. Understanding these complications is vital for effectively managing patient safety and ensuring positive outcomes in dental or medical procedures.
