Background: Interscalene Blockade is widely used to ensure analgesia in surgery involving the shoulder. Both i.v. and perineural dexamethasone seem to be able to prolong the block duration and can therefore be used to reduce the use of analgesics. However most of the studies focusing on dexamethasone as an additive use large volumes (20 ml) of local anesthetic agent. Larger volumes may be associated with a higher rate of complications. Therefore the hypothesis of this study is to prove whether dexamethasone is also able to prolong the pain free time when given together with a low volume (10 ml) of anesthetic agent. Methods: The study was conducted as a prospective, double-blinded randomized trial. Patients with arthroscopic surgery of the shoulder were included in our study. The blockade was performed using ultrasound guidance to ensure a low rate of block failure. We used eight milli.. View More»
