Shoulder Nerve Block Experience After Keyhole Surgery
Official title: Patient Experience of Benefits and Limitations of Single Injection Peripheral Nerve Block for Shoulder Surgery: A Cross-sectional Survey
Run by University Health Network, Toronto · NCT07641842 · Data updated 2026-11-12
This study asks adults who had outpatient shoulder arthroscopic surgery with a single-shot nerve block to share their pain and recovery experiences to see if a nerve catheter might help some patients longer after surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older undergoing outpatient arthroscopic shoulder surgery with a single-shot nerve block at the participating Toronto hospitals, able to communicate in English.
✕Probably not a fit
Patients who do not anticipate rebound pain or who are not considering catheter-based pain relief would have no expected benefit.

What this trial studies
This cross-sectional survey at Toronto Western Hospital and Women’s College Hospital collects patient experiences following keyhole shoulder surgery with an initial single-shot nerve block and general anesthesia. It aims to identify whether extending pain relief with a nerve catheter could reduce rebound pain compared to the standard single-shot block. Participants must be adults able to communicate in English and undergoing outpatient arthroscopic shoulder surgery. The study discusses pain, recovery, and potential subgroups that may benefit from continuous nerve block infusion. No specific interventions are described beyond collecting patient-reported information.
Why it matters
Potential benefit: If successful, findings could help tailor pain management after shoulder surgery by identifying who might benefit from a continuous nerve block.
How similar studies have gone: Previous evidence suggests longer-duration nerve block may reduce rebound pain, but this study focuses on patient experiences rather than a randomized comparison.
