“ENDOTRACHEAL TUBE CUFF PRESSURE MONITORING USING PREFIXED VOLUME AIR VERSUS MANOMETER IN GENERAL ANAESTHESIA”

Background And Objective: The endotracheal tube (ETT) cuff seals the airway, preventing leakage and aspiration of pharyngeal contents into the trachea during ventilation. The Endotracheal tube cuff (ETT) endorses effective mechanical ventilation by ensuring a seal within the subglottic tracheal structures. Maintaining an appropriate intracuff pressure is critical for optimal mechanical ventilation, avoiding difculties caused by under ination or over ination of the cuff. The purpose of this study is to compare the ETT cuff pressure and its variation with the prexed volume air method of cuff ination and employing a pressure manometer in terms of cuff pressure variation, under ination, and over ination. This study included 100 adult patients over the age of 18 who underwent elective Methods: surgery. Patients were randomized using prospective comparative study into 2 groups of 50 each: Group A - cuff inated by Prexed volume air; Group B - cuff inated by pressure manometer. Cuff pressures were monitored on a regular basis. Under ination of an ET tube cuff is dened as a cuff pressure less than 25 cm H2O and over ination as a cuff pressure greater than 35 cm H2O. The cuff Results: pressure assessed at different time intervals was statistically signicant in this study. At each interval, the cuff pressure in Group B was within the safe range. Patients in Group A, on the contrary hand, had cuff pressures that were above the normal range. Routine use of cuff pressure manometer at regular intervals helps to maintain cuff pressure a Conclusion: t a safe range and prevents abnormal variations in mechanically ventilated patients in elective surgeries.
