U.S., Oct. 16 -- ClinicalTrials.gov registry received information related to the study (NCT07216820) titled 'Interscalene vs Phrenic-sparing Blocks in Obesity and Effect of Maximum Inspiratory Pressure' on Oct. 13.
Brief Summary: The goal of this clinical trial is to learn whether a phrenic-sparing nerve block can lower early breathing problems after shoulder surgery in adults with obesity, and whether a simple breathing-strength test (maximum inspiratory pressure, MIP) helps identify who is at higher risk. The main questions are:
Does the phrenic-sparing approach reduce breathlessness or oxygen need in the recovery room (30-60 minutes after arrival)? Do patients have similar pain control and opioid use compared with the standard intersca...
