What this trial studies

This clinical trial investigates the effectiveness of the ultrasound-guided retroclavicular approach to the infraclavicular region (RAPTIR) brachial plexus block for providing anesthesia during upper limb orthopedic surgeries. The RAPTIR technique is designed to deliver reliable and dense anesthesia with a single injection, making it a potentially advantageous option for various surgical procedures. The study aims to evaluate the outcomes of this nerve block in terms of pain management and overall patient satisfaction. Participants will receive the retroclavicular block prior to their surgical procedures to assess its efficacy.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management for patients undergoing upper limb surgeries.

How similar studies have gone: Previous studies have shown success with similar ultrasound-guided nerve block techniques, indicating a promising approach for pain management.
