Central nervous system (CNS)symptoms such as loss of responsiveness,disorientation,tremors,or seizures must be treated conventionally by ensuring oxygenation and ventilation,securing the airway to protect aspiration of gastric contents in patients at risk,administering anticonvulsants,and instituting Advanced Cardiac Life Support protocols in the case of cardiac arrest.While widely used,local anesthetics are not free from hazards.A recent FDA warning notes that the potential life-threatening complications,"such as irregular heartbeat,seizures,breathing difficulties,coma and even death," can occur when applied to a large area of skin or when the area of application is covered.An example of a newer treatment for local anesthetic toxicity is lipid emulsion rescue therapy,which has been used in isolated situations for bupivacaine toxicity.
