Tracheal Cuff Pressure and Postoperative Complications

This prospective observational study aims to identify risk factors for tracheal mucosal injuries caused by orotracheal tube use during the intraoperative period in patients undergoing elective surgeries at the Hospital de Clínicas de Porto Alegre. The study will recruit patients sequentially for elective procedures requiring general anesthesia and orotracheal intubation. Primary outcomes include symptoms such as hoarseness, pharyngolaryngeal pain, cough, and hemoptysis, assessed up to 30 days post-surgery. A risk score for tracheal injuries will be derived.
