Summary
This study will compare perineural dexamethasone 2mg and perineural mixture of dexamethasone
2mg plus dexmedetomidine 50mcg DX plus DXD as adjuvants to local anesthetics for
ultrasound-guided infraclavicular brachial plexus blocks (ICBs). The protocol is designed as
a superiority trial and hypothesizes that the mixture of both drugs results in longer block
duration. Furthermore, since analgesic and sensory duration can be influenced by the intake
of pain medications and surgical trauma to small cutaneous nerves, respectively, motor block
duration was selected as the main outcome to better target the action of both adjuvants on
the brachial plexus.
