Tracheal Tube Cuff Pressure and Postoperative Hoarseness and Pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective observational study will enroll adults undergoing elective procedures with general anesthesia and orotracheal intubation at Hospital de Clínicas de Porto Alegre. Researchers will collect data on cuff pressure, tube characteristics, and patient factors to identify risk factors for tracheal mucosal injuries and related postoperative symptoms. Multivariate analysis will be used to derive a risk score for predicting tracheal injuries, with outcomes assessed up to 30 days after surgery. The goal is to better understand how intraoperative cuff management relates to postoperative throat and airway symptoms. The study does not involve an intervention beyond observation and data collection.
