ABSTRACT

Local anaesthetic (LA) toxicity is the most fatal complication of peripheral nerve block techniques. Accidental intravascular application or use of doses above the safety range are the most common cause of toxicity. Bupivacaine is a long-acting LA frequently used for long procedures or those associated with significant post-procedural pain. Fatal central nervous system and cardiovascular system toxicity are described. In this paper, we reported a young patient who showed LA toxicity symptoms 7 h after an infraclavicular peripheral block.
