Seizure complicating interscalene brachail plexus block

Abstract

We describe a case of seizure occurring immediately after completion of interscalene brachial plexus block, using 20mls mixture of 10mls of 0.5% bupivacaine and 10mls of 2% lidocaine with adrenaline for post operative analgesia. Seizure occurred despite negative test aspiration and non response to the use of 0.5mls of 2% lidocaine with adrenaline as intravascular markers, Seizures was aborted with the use of 10mg diazepam. We conclude that this seizure was due to inadvertent intravascular deposition of the mixture of local anaesthetic agent used despite the precautionary measures.
