ABSTRACTIntroduction: During intubation, the cuff pressure the endotracheal tube seals the trachea avoiding aspiration of gastric material. In robotic surgery, the combination of deep Trendelenburg position, capnoperitoneo, hypothermia and time of the procedure can lead to changes in endotracheal tube cuff pressure, increasing tracheal morbidity. Objective: To determine the changes in endotracheal tube cuff pressure during the transoperative period in patients undergoing prostactomy due to robotic surgery. Material and methods: Thirty patients were included. Surgical times and endotracheal tube cuff pressure values were measured after the induction of anesthesia (basal T), 120 minutes after initiating CO2 insufflation (T2h), at 240 minutes (T4h) and prior to extubation (final T.), all measurements were made with a single manometer. A statistical significance associated with a value of p ≤ 0.05 was considered. Results: The age of the patients was 65.53 ± 5.92 years, the position of trendelenburg with ≥ 30o 53.3%, the anesthetic and surgical time was 377.3 ± 67.9 min 326.7 ± 77.4 min, respectively. The measurements of the cuff were at two hours 29.6 ± 5.8 cmH2O, at four hours 28.7 ± 7.6 cmH2O and at extubation 18.5 ± 7.5 cmH2O. The pressure of the ETT cuff was higher in the group that presented obesity p ‹ 0.05. In this investigation no changes related to the capnoperitoneum and temperature were presented.
