Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The block has been well described in the anesthesia community since it was first introduced by Hebbard and Royse in 2007 . In 2017, Luftig . first described the block's use in the ED setting for a variety of indications . Because of its different needle entry point, the retro clavicular (RCB) approach offers an almost perpendicular needle-ultrasound (US) beam angle.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Dexamethasone is a corticosteroid drug that has been used as an adjuvant to reduce postoperative pain.
The use of peri neural dexamethasone (i.e. dexamethasone added to the local anesthesia solution) as an adjuvant to peripheral nerve block to improve analgesia provided by local anesthetic alone . Peri neural dexamethasone, as an adjuvant to peripheral nerve block, has been associated with faster onset of anesthesia , longer duration of anesthesia/analgesia decreased postoperative pain intensity and decreased postoperative analgesia requirements compared with local anaesthetic alone . The exact mechanism by which dexamethasone reduces pain is not known. The decrease in pain intensity and the prolonged analgesia attained with the use of perineural dexamethasone may be the result of a local, or systemic action, or both . Dexamethasone may act locally on glucocorticosteroid receptors to induce vasoconstriction, thereby decreasing systemic absorption of local anaesthetics . Other potential mechanisms of action include suppression of C-fibre transmission of pain signals and direct action on the nerve cell to reduce neural discharge . Dexamethasone may act systemically by reducing the inflammatory response caused by surgical tissue injury .
