An observational study in Dyspnea After Interscalene Nerve Block, sponsored by University of North Carolina, Chapel Hill. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-08-12.
Sponsored by University of North Carolina, Chapel Hill · Observational
The study aims to explore if Maximum Inspiratory Pressure can predict postoperative breathlessness in obese patients receiving interscalene blocks for shoulder surgery.
The main question is: does baseline Maximum Inspiratory Pressure have any association with postoperative breathlessness after interscalene blocks in class 2 or higher obese patients (BMI>35).
Preoperative and postoperative lung volumes, pressures, breathlessness score and respiratory outcomes will be measured on participants already receiving shoulder surgery with interscalene blocks.
656 studies on the registry are indexed under Dyspnea; 153 are open to participants now.
This study's enrollment of 45 is below the median of 122 across 204 observational studies indexed under Dyspnea.
