Finding the best local anesthetic volume for pain relief after shoulder surgery
Optimal Effective Local Anesthetic Volume for Pain Relief Using Brachial Plexus Block Utilizing Continuous Reassessment Method for Arthroscopic Rotator Cuff Shoulder Surgery
This study is testing how much local anesthetic is best for reducing pain after shoulder surgery to see if it helps patients feel better with fewer side effects.

What this trial studies
This study investigates the optimal volume of local anesthetic used in brachial plexus blocks to manage post-operative pain in patients undergoing arthroscopic rotator cuff surgery. It employs a novel Continuous Reassessment Method to evaluate both the effectiveness of the block and any potential side effects, such as lung dysfunction. Patients will be assessed for pain relief using a verbal analogue scale 60 minutes after surgery, allowing for precise adjustments in anesthetic volume based on real-time feedback.
Who should consider this trial
Good fit: Ideal candidates include adults over 18 years old who are surgical candidates for arthroscopic rotator cuff surgery and have an ASA classification of I-III.
Not a fit: Patients with allergies to ropivacaine, chronic opioid use, or significant lung disease may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing shoulder surgery.
How similar studies have performed: Other studies have explored similar approaches to pain management with nerve blocks, indicating potential for success in this area.
