Inadvertent subdural spread complicating cervical epidural steroid injection with local anaesthetic agent

Anaesth Intensive Care. 2003 Oct;31(5):570-2. doi: 10.1177/0310057X0303100512.

Abstract

Although cervical epidural steroid injection with local anaesthetic is considered a safe technique and widely practiced, complications may occur. We report a patient experiencing unexpected delayed high block, moderate hypotension and unconsciousness eight to ten minutes after an apparently normal cervical epidural steroid injection. The most probable diagnosis was a subdural block. Anatomical peculiarities of the epidural and subdural space in the cervical region increase the risk of subdural spread during cervical epidural injection. Fluoroscopic guidance is important during cervical epidural injection to increase certainty of correct needle placement, thus minimizing the risk of complications.
