Abstract

Background: Infraclavicular brachial plexus block is a suitable regional anesthesia technique for hand, wrist and elbow operations and it is usually performed in conjunction with nerve stimulation. We aimed to compare the onset times of sensory block with equipotential 0.25% bupivacaine and 0.5% bupivacaine.
Methods: This prospective double-blinded randomized controlled study was conducted on 60 patients, aged > 18 years, with ASA physical status I–III, and scheduled for upper extremity surgery with infraclavicular brachial plexus block. The participants were randomized into two equal groups; group I in which ICB performed with 0.25%, 20 mL bupivacaine and group II in which ICB performed with 0.5% 20 mL bupivacaine.
Results: Regarding the block performance, group II showed earlier onset time and longer duration of sensory and motor blocks compared to group I (P
