SUPraclavicular Block for Emergency Reduction of Upper Limb Injuries Versus Bier Block (SUPERB Trial)
The SUPERB trial compared ultrasound-guided supraclavicular block with Bier block for distal forearm fracture reduction in the ED. Both provided excellent pain relief, with supraclavicular block noninferior and offering longer analgesia. Safe, feasible, and well-tolerated, this trial supports expanding regional anaesthesia options for emergency physicians managing upper limb injuries.
