Retroclavicular Block in Vascular Surgey

Status Not yet recruiting

Clinical Trial Summary

The retroclavicular (coracoid) approach for brachial plexus anesthesia is recognized for its facility and simplicity to perform . 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.

Clinical Trial Description

Regional anesthesia (RA) offers several advantages over general anesthesia (GA) for upper limb orthopedic surgery. One of the advantages is the improvement in postoperative pain, which leads to decreased use of postoperative opioids needs and reduces the recovery time for patients . A variety of approaches for regional blockade for upper extremity surgery have been described. 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 . ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
