Comparison of Endotracheal Cuff Pressure Changes with Head and Neck in Extension Position

Background:The cuff of the endotracheal tube is inflated when general anesthesia is administered to provide a sufficient seal and avoid micro-aspiration.Complications may arise from overinflating the cuff, which lowers mucosal perfusion.The present study investigates how variations in head and neck posture affect intracuff pressure.Methods: It is parallel group research that is not randomized.Included were fifty adult patients, ages twenty to sixty, who were scheduled for elective GA surgery with endotracheal intubation.Patients having neck extension surgery have to be in one of the categories.Patients in Group 1 underwent head and neck procedures while in a neutral supine posture.A manometer was used to measure intracuff pressure first with the head and neck in the neutral supine position and then with the head and neck extended.The head and neck were instantly put back in neutral.At 15 and 30 minutes, the intracuff pressure was measured again.Result: The findings indicated a considerable rise in pressure between the neutral and extension positions.Although there was no discernible difference between the groups, a considerable incremental pressure rise was seen in both the neck in the neutral position and the neck extended.Conclusion: Cuff pressure rises noticeably with head extension and then progressively over time.Continuous monitoring and management of the endotracheal tube's cuff pressure is necessary when the head position is altered for extended surgical operations.
