Ultrasound-guided supracondylar radial nerve block for Colles Fractures in the ED

All adult patients referred to the emergency department (ED) with distal radius fractures were asked to provide informed consent for participation in the study when the performer of USG-guided nerve block was on duty. A single emergency physician (EP), experienced in bedside ultrasound using the M7 model ultrasound machine with 5- to 12-MHz high-frequency linear transducer (Mindray Bio-Medical Electronics Co, Shenzen, China), performed USG-guided supracondylar nerve block with an average 10 mL 2% lidocaine for each patient; this procedure required 5.5 minutes on average when he is on duty.
