Ultrasound-Guided Low-Volume Brachial Plexus Block in Supraclavicular Region for Shoulder Reduction in Emergency Department
Summary
This NIH ClinicalTrials.gov registry entry documents NCT07544485, a retrospective, monocentric observational study analyzing routinely collected clinical data from an orthopedic emergency department between February 2018 and February 2024. 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 for adult patients with acute shoulder dislocation. Outcomes assessed include procedural success, block-related complications, and temporal trends reflecting adoption of the technique over time.

What changed
This NIH ClinicalTrials.gov registry entry documents NCT07544485, an observational study analyzing the use of ultrasound-guided low-volume brachial plexus block in the supraclavicular region for shoulder reduction in the emergency department setting. The retrospective, single-center study collected data from February 2018 through February 2024 on adult patients presenting with acute shoulder dislocation. The study evaluates procedural success rates, block-related complications, and temporal trends in adoption of the technique.
For healthcare providers and clinical researchers, this registry entry documents the study parameters and methodology but does not establish compliance obligations or regulatory requirements. Emergency department clinicians and researchers studying regional anesthesia approaches to shoulder dislocation may wish to monitor this registry for publication of results upon study completion.

Ultrasound-Guided Low-Volume Brachial Plexus Block in the Supraclavicular Region for Shoulder Reduction in the Emergency Department
Observational NCT07544485 Kind: OBSERVATIONAL Apr 22, 2026
Abstract
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.
Conditions: Shoulder Dislocation, Joint Dislocation
Interventions: Ultrasound-guided brachial plexus block
