The aim of this prospective observational study is to evaluate the effect of endotracheal cuff pressure management on postoperative complications in patients undergoing surgery under general anesthesia. Specifically, patients whose endotracheal cuff pressure is maintained at an optimal level using a manometer will be compared with those whose cuff pressure is assessed using the conventional palpation method.
The primary question the study aims to answer is whether maintaining endotracheal cuff pressure at an optimal level with a manometer reduces the incidence of postoperative airway-related complications compared with the classical palpation technique.
Patients aged 18-75 years
American Society of Anesthesiologists (ASA) physical status I-III
Body mass index (BMI) between 18 and 30 kg/m²
Undergoing surgery under general anesthesia
Patients younger than 18 years or older than 75 years
American Society of Anesthesiologists (ASA) physical status IV-VI
Patients undergoing head and neck surgery
History of chronic pulmonary disease (e.g., asthma, chronic obstructive pulmonary disease)
The study population will consist of adult patients aged 18-75 years, classified as American Society of Anesthesiologists (ASA) physical status I-III, with a body mass index between 18 and 30 kg/m², who are scheduled to undergo elective surgery under general anesthesia requiring endotracheal intubation. Only patients with successful intubation on the first attempt will be included.
