[Generalized seizure during placement of an axillary plexus block]

Abstract

A young patient experienced a generalized seizure during the placement of an axillary plexus block. The mechanisms, essentially the presumed intravascular administration, which led to the local anesthetic toxicity as the cause of this event, are discussed. This case is an example of how visualization of the anatomy by ultrasound can give a false impression when certain details are not respected. It is assumed that the main mechanism in this case was venous compression by the ultrasound transducer.
