Local anesthetic (LA) toxicity is the most fatal complication of peripheral nerve block techniques. Inadvertent intravascular administration or higher dose LAs above safety margins are the main causes of toxicity. In recent years, some case reports have been published in the literature about successful treatment of LA toxicity unresponsive to standard resuscitation efforts with lipid infusions. We aimed to report about a patient who suffered from a LA toxicity after sciatic + femoral nerve block for the removal of an infected knee prosthesis who was successfully treated with lipid infusion before development of cardiac arrest.
