Comparison of the effectiveness of traditional mask ventilation technique with Tracheal Tube in Pharynx in patients having Anticipated difficult Ventilation: A prospective randomised Open-Label Crossover Trial

This study is a prospective, randomized, open-label crossover trial comparing the effectiveness of traditional mask ventilation with the tracheal tube in pharynx (TTIP) technique in patients with anticipated difficult mask ventilation. The primary objective is to compare expired tidal volumes achieved by both methods, while secondary outcomes include other ventilation parameters, success rate, order of effectiveness, and adverse events. A total of 148 adult patients undergoing elective surgery under general anaesthesia will be enrolled, selected based on predictors like obesity, beard, edentulism, elderly age, and snoring. Following standard induction with fentanyl, propofol, and rocuronium, patients will be ventilated using both methods in a randomized sequence. TTIP involves blind insertion of an endotracheal tube into the pharynx to bypass common causes of upper airway obstruction. The study aims to determine whether TTIP can be a reliable alternative to mask ventilation in managing anticipated difficult airways.
