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. 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. Repeated, long-term, perineural administration of dexmedetomidine with BPB may be suitable for alleviating refractory CRPS pain. © 2019 John Wiley & Sons Ltd.
