Summary
A standard interscalene nerve block is performed with long acting local anesthetic
(bupivacaine or ropivacaine in concentrations varying from 0.25% to 0.75%). The purpose of
this study is to investigate the effect of the addition of perineural dexamethasone (4mg) to
a standard ropivacaine solution (0.5%) on analgesic duration of low dose interscalene block
compared to ropivacaine alone for interscalene block with systemic dexamethasone.
Ropivacaine is not an intervention as a local anesthetic is pre-requisite to performing a
nerve block.
