Design outcomes

Primary

Measure	Time frame
To find out if the below two USG parameters can predict difficult airway in adult obese and non-obese patients by correlating with Cormack and Lehane grading 1)DSHB - distance from skin to hyoid bone 2)DSEM - distance from skin to epiglottis, at the level of thyrohyoid membraneTimepoint: 10 minutes	—

Secondary

Measure	Time frame
To note the number of attempts for intubation. - Change of blade, use of stylet or bougie to aid intubation RTimepoint: 3 minutes	—
