Text: Compared with the supraclavicular and infraclavicular approaches, ultrasound-guided AXBs required a higher number of needle passes (6. 1 [SD, 2. 0] vs 2. 0-2. 6 [SD, 1. 1-1. 8] ; both P < or = 0. 001), a longer needling time (7. 4 mins [SD, 2. 2 mins] vs 4. 9-5. 5 mins [SD, 1. 9-4. 2 mins] ; both P < or = 0. 016), and a longer performance time (8. 5 mins [SD, 2. 3 mins] vs 6. 0-6. 2 mins [SD, 2. 1-4. 5 mins] ; both P < or = 0. 008).
