Intervention / Comparator Agent  
Type  Name  Details 
Intervention  ETT held at 18 cm from tip  Participants will be randomly allocated to one of two groups. In Group A, the anesthesiologist will hold the endotracheal tube at the 18 cm mark from the distal tip during direct laryngoscopy. In Group B, the anesthesiologist will hold the endotracheal tube at 26 cm mark from the distal tip. All patients will undergo standardized induction of general anesthesia and tracheal intubation using a Macintosh laryngoscope and appropriately sized endotracheal tubes. Intubations will be performed by trainee anesthesiologists under supervision. All other aspects of airway management and anesthesia technique will be standardized. The intervention is a one-time intraoperative manoeuvre. The total duration of the intervention is from insertion of the endotracheal tube into the mouth until successful intubation confirmed by capnography approximately 10–30 seconds

Brief Summary   This randomised interventional study aims to compare two different holding positions of the endotracheal tube(18cm versus 26 cm from the tip)during direct laryngoscopy for tracheal intubation in adult patients undergoing elective surgery under general anaesthesia. Participants will be randomly allocated to either group. The primary outcome is time to successful intubation, measured from the insertion of the laryngoscope to the appearance of a sustained end tidal carbon dioxide waveform. Secondary outcomes include intubation difficulty score, first pass success rate, number of optimisation manouvers, Cormack Lehane grade and airway related complications. The study seeks to identify whether tube holding position influences ease and efficiency of tracheal intubation.
