What is the best initial management of a toxic reaction to a local anesthetic?

Explanation:
In a toxic reaction to a local anesthetic, the priority is to support airway, breathing, and circulation. Start by providing high-flow oxygen to ensure maximal oxygen delivery to the brain and heart, and position the patient to maintain a clear airway and effective ventilation. This stabilizes the patient while more specific treatments are planned. Other options don’t address the immediate safety needs: antibiotics have no role in an acute LAST event, and urgent surgery is not indicated. Epinephrine may be used later if cardiovascular instability develops, but it isn’t the first step. If symptoms progress to seizures or cardiac complications, manage seizures with benzodiazepines and escalate to lipid emulsion therapy as part of the evolving treatment strategy.
