Assessment of endotracheal tube cuff pressure after tracheal intubation during general anaesthesia

Background and purpose: The cuff of tracheal tube is important and secures the airway during anaesthesia. This study evaluates the effect of endotracheal tube cuff pressure after tracheal intubation during general anesthesia. Materials and methods: This is a descriptive observational study that recruits 500 ASA physical status I and II patients undergoing elective surgery under general anaesthesia. The tracheal cuff pressure was asessed using manometer instrument 10 min after tracheal intubation. Results: It has been observed that at a mean intracuff pressure of 92 ±131 cm H20 more than 95% of patients were over-inflated. There was no significant association between the cuff pressure and how experienced were the anaesthesiologists (p<0.05). Conclusion: Routine method to inflate the tracheal tube cuff is not suitable during induction of anesthesia, because it results in over-inflation.
