Randomized Controlled TrialA randomized comparison between 3 combinations of volume and concentration of lidocaine for ultrasound-guided infraclavicular block.
This prospective, randomized, observer-blinded study compared 3 combinations of volume and concentration using the same total dose of lidocaine for ultrasound-guided infraclavicular block. ⋯ Using an identical dose (525 mg) of adrenalized lidocaine for ultrasound-guided infraclavicular block, we found no differences in onset time among 3 commonly used concentrations (1%, 1.5%, and 2%). Further studies are required to determine the optimal combination of volume and concentration of lidocaine for other ultrasound-guided approaches to the brachial plexus.
