Design outcomes

Primary

Measure	Time frame
Intubation Difficulty Scale Score (IDS) which is a seven point scoring system as described by Adnet comprising of: Number of attempts of tracheal tube passes Number of operators Number of alternative techniques (bougie, change of blade size) Glottic exposure (Cormack and Lehane grade minus 1) Lifting force required during laryngoscopy Necessity for Laryngeal pressure Vocal cord mobility Timepoint: At the time of intubation	—
