Preoperative Maximum Inspiratory Pressure and Outcomes After Interscalene Block in Obese Patients
- Conditions
- Dyspnea After Interscalene Nerve Block
- Registration Number
- NCT06549244
- Lead Sponsor
- University of North Carolina, Chapel Hill
- Brief Summary
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.
