Summary
Interscalene brachial plexus block provides excellent but time limited analgesia. Intravenous
dexamethasone increases the analgesic duration of a single-shot interscalene block with
ropivacaine for shoulder arthroscopic surgery. We want to evaluate the effect of two
different doses (dexamethasone 10 mg i.v. vs 4 mg i.v. vs placebo) on the analgesic duration
of a single-shot inter scalene block. Our study hypothesis is that dexamethasone 4 mg i.v. is
equivalent to dexamethasone10 mg i.v. in prolonging the analgesic duration of a single-shot
interscalene block with ropivacaine.
