A Prospective, Randomized Comparison Between Double-, Triple-, and Quadruple-Injection Ultrasound-Guided Axillary Brachial Plexus Block
Regional Anesthesia and Pain Medicine, 05/10/2012
Tran DQH et al. – Double–, triple–, and quadruple–injection ultrasound (US)–guided perivascular axillary brachial plexus block (AXB) result in comparable success rates and total anesthesia–related times. Because it requires fewer needle passes, the double–injection technique provides a simple alternative for US–guided AXB.
