What are two signs of local anesthetic toxicity?

Local anesthetic toxicity can manifest in various ways, particularly affecting the central nervous system and, in severe cases, the cardiovascular system. Dizziness and seizures are significant signs of toxicity that arise from the impact of local anesthetics on the central nervous system. When local anesthetics are administered, they work by blocking nerve transmission to provide pain relief. However, if the anesthetic enters the bloodstream in excessive amounts or if the patient has certain underlying vulnerabilities, it can lead to neurotoxic effects. Dizziness may occur as a result of altered brain function or neurological overstimulation, while seizures indicate severe central nervous system involvement. These physiological responses can pose serious risks if not identified and treated promptly. Other signs of toxicity, though present in the remaining options, are either less critical or more common but not specific to local anesthetics. Recognizing dizziness and seizures as key indicators enables dental professionals to respond appropriately and mitigate risks associated with local anesthetic administration.
