Recurring brachial plexus neuropathy in a diabetic patient after shoulder surgery and continuous interscalene block.

IMPLICATIONS: The performance of regional blockade on a patient with a preexisting neurologic condition or a history of neurologic complications after regional anesthesia is controversial. We present a case of recurring brachial plexus neuropathy in a diabetic patient after two shoulder procedures performed 4 mo apart. In both cases, the patient underwent intensive physical therapy with continuous postoperative interscalene analgesia.
