Design outcomes

Primary

MeasureTime frame
Proportional Difference in Cormack Lehane grading in two laryngoscopy positions- sniffing position (SP) versus position attained by horizontal alignment of external auditory meatus- sternal notch line (AM-S)Timepoint: 5 minutes—

Secondary

MeasureTime frame
Determine difference in Intubation Difficulty Scale (IDS) between two positionsTimepoint: Within 5 minutes from achieving testing position;Determine difference in mean intubation time taken while performing laryngoscopy in SP position versus position attained by alignment of AM-STimepoint: Within 5 minutes of testing position;Determine mean pillow height required for alignment of AM-S positionTimepoint: 15 minutes after achieving AM-S position—
