Retroclavicular Approach vs Infraclavicular Approach for Plexic Bloc Anesthesia of the Upper Limb: a Multi-centric Non-inferiority Randomised Controlled Trial

Detailed Summary

Locoregional anesthesia provides several advantages over general anesthesia in terms of postoperative pain, decreased postoperative opioid needs and reduced recovery time for patients undergoing orthopaedic surgery. For upper limb surgery, the coracoid infraclavicular brachial plexus block is generally preferred because of its simplicity and effectiveness but, needle visibility remains a challenge because of the angle between the ultrasound beam and the needle. The retroclavicular approach for brachial plexus anesthesia requires an angle between the needle and the ultrasound beam that is less steep than the angle required to perform an infraclavicular coracoid block. This approach has already been proven effective and safe in the past. The general objective is to provide a formal comparison between the retroclavicular approach and coracoid infraclavicular approach for brachial plexus anaesthesia. This study will delineate the differences between the two techniques.
