Design outcomes

Primary

Measure	Time frame
-To note down the change in laryngeal exposure (percentage of Glottic Opening {POGO} scoreTimepoint: At baseline, the time of Laryngoscopy and intubation	—

Secondary

Measure	Time frame
To compare in both groups- • Cormack Lehane Grading • Time required for intubation (TRI) • Number of intubation attempts • Number of Operators • Number of Alternative techniques (Stylet, Bougie-Guided intubation) • Lifting force required (Normal/ Increased) • Need for external laryngeal maneuver • First pass intubation success • Vocal cord mobility (Abducted/ Adducted) • Effort during intubation (assessed based on Numeric rating scale, 0 being no effort, 10 being maximal effort), and • Complications during intubation (esophageal intubation, hypoxia, and hypotension) will be recorded. Timepoint: At baseline, the time of Laryngoscopy and intubation	—
