What is Local Anesthetic Dose?

The local anesthetic dose refers to the maximum safe amount of medication that can be administered to a patient to produce local anesthesia or analgesia without causing systemic toxicity. Toxicity from local anesthetics can affect the central nervous system and cardiovascular system, being potentially fatal if not recognized and treated appropriately.
