Case ReportsSubdural anesthesia as a complication of an interscalene brachial plexus block. Case report.
Interscalene brachial plexus block is performed in the groove between the anterior and middle scalene muscles at the level of C6, just over the transverse process. Injection occurs within 1-2 cm of the dural sleeve and could be misdirected into the epidural, subdural, or subarachnoid spaces. ⋯ The case represents a partial injection of local anesthetic intended for the interscalene brachial plexus into the subdural space. The diagnosis is based on the normal evolution of the block into full motor and sensory anesthesia of the ipsilateral brachial plexus that evolved into a patchy, sensory, and motor block involving many dermatomes outside the brachial plexus, with minimal sympathetic block, and evidence of a normal interscalene block on emergence from general anesthesia. Subdural injection must be considered when unusual motor and sensory block occurs after interscalene block, especially after a time interval too long for epidural or subarachnoid injection, or with minimal evidence of sympathetic block, after suspected high central block injection.

Clinical TrialInterscalene brachial plexus block for shoulder surgery.
To evaluate the efficacy of interscalene brachial plexus block as the primary anesthetic for shoulder surgery, the influence on blood loss, and the rate of complication. ⋯ Interscalene anesthesia is an effective anesthetic for elective shoulder surgery that may decrease intraoperative blood loss with a low complication rate.
