Is this trial a fit for you?
✓Likely a good fit
Adults with BMI over 30 undergoing surgeries longer than one hour using a video laryngeal mask, ASA I–III, without anticipated difficult airway.
✕Probably not a fit
Patients with BMI under 30, pregnancy, or anticipated difficult airway may not be the target and could have different responses.

What this trial studies
This observational study examines how administering rocuronium, a muscle relaxant, before using a video laryngeal mask affects postoperative sore throat in procedures longer than one hour. It also looks at whether rocuronium influences middle ear pressure, oropharyngeal leak pressure, and other airway-related factors. Participants are adults with BMI over 30 undergoing surgery with VLMAs for at least 60 minutes. Data will be collected at the end of surgery and during the immediate postoperative period to compare outcomes with and without the muscle relaxant, within the specified eligibility criteria.
Why it matters
Potential benefit: If rocuronium reduces sore throat or stabilizes airway pressures, patients could experience less postoperative discomfort and improved recovery after surgeries using VLMAs.
How similar studies have gone: Previous research in airway management has shown variable effects of neuromuscular blockers on postoperative throat symptoms and airway pressures, making this area exploratory.
