Efficacy of adjuvant dexmedetomidine in supraclavicular brachial plexus block for intractable complex regional pain syndrome: A case report with a 3-year follow-up

초록

What is known and objective Pain management for complex regional pain syndrome (CRPS) is challenging. When added to local anaesthetics, dexmedetomidine prolongs the duration of the block and improves analgesia. The effect of long-term dexmedetomidine use in the brachial plexus block (BPB) for CRPS is unknown. Case description Here, we describe a case of satisfactory pain relief after supraclavicular BPB with dexmedetomidine every 1-3 months over 2 years (10 treatments), in a patient with severe upper extremity CRPS-related pain. What is new and conclusion Repeated, long-term, perineural administration of dexmedetomidine with BPB may be suitable for alleviating refractory CRPS pain.
