Clinical Trial Summary

The main objective of the study is to demonstrate the efficacy of Dexmedetomidine on the prolongation of analgesia obtained by interscalenic bloc of the brachial plexus and intravenous injection of Dexamethasone (efficacy objective).

Description:

This is an interventional, comparative, randomized, controlled study versus reference treatment, in 2 parallel groups, double blind (patient and evaluator), multicenter, aiming to demonstrate the superiority of This is an interventional, comparative, randomized, controlled study versus reference treatment, in 2 parallel groups, double blind (patient and evaluator), multicenter, aiming to demonstrate the superiority of Dexmedetomidine over the absence of Dexmedetomidine, in adjuvantation of a loco regional anesthesia (interscalenic bloc of the brachial plexus + intravenous injection of Dexamethasone), on the prolongation of the analgesia, following a surgery of the rotator cuff of the shoulder under arthroscopy.

Patients will be randomized into 2 groups according to the treatment received:

• Dexmedetomidine;

• Nothing (control arm). The investigator (anesthesiologist) who will perform the randomization will not be blinded to the treatment.
