Design outcomes

Primary

Measure	Time frame
Proportion of patients with successful first-attempt intubation with video laryngoscope vs hybrid technique using both video laryngoscope and flexible bronchoscope in adult patients with predicted difficult intubationTimepoint: Immediately after completion of the first intubation attempt	—

Secondary

Measure	Time frame
Time taken in seconds (Mean ± SD) for tracheal intubation in first attempt in both the groupsTimepoint: Time from introduction of laryngoscope to the appearance of first square wave capnographic trace in first attempt;Proportion of patients with failed intubation in both the groupsTimepoint: After completion of 2 allowed intubation attempts in each patient.;Proportion of patients requiring Optimal External Laryngeal Manipulation for achieving successful intubation in both the groupsTimepoint: Assessed at the time of intubation attempt;Proportion of patients with oro-dental trauma in both the groupsTimepoint: Assessed during or immediately after intubation	—
