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.

Eligible Conditions
  • Shoulder Pain

Screening ~ 3 weeks
Treatment ~ Varies
Follow Up ~recovery (immediately post-surgical, up to 3 hours)
