Ultrasound-Guided Low-Volume Brachial Plexus Block in the Supraclavicular Region for Shoulder Reduction in the Emergency Department

Acute shoulder dislocation is a common and painful condition in the emergency department (ED). Procedural sedation is widely used to facilitate reduction but is associated with potential risks and resource use. Ultrasound-guided regional anesthesia has emerged as an alternative approach. This retrospective, monocentric observational study analyzes routinely collected clinical data from an orthopedic ED between February 2018 and February 2024. Adult patients with acute shoulder dislocation are included. The study evaluates the feasibility, safety, and clinical implementation of low-volume (approximately 5 ml local anesthetic) ultrasound-guided brachial plexus block in the supraclavicular region. Outcomes include procedural success, block-related complications, and temporal trends reflecting the adoption of the technique over time.
