Design outcomes

Primary

MeasureTime frame
To determine the association between Wilsons score and the ultrasound airway parameters (DSE, DSH, Tongue thickness) in predicting difficult airwaysTimepoint: Wilson score will be assessed 1 day before surgery and Ultrasound of the upper airway on the day of surgery—

Secondary

MeasureTime frame
To identify the optimal cut-off values for these ultrasound parameters. To investigate gender wise differences in airway parameters. To evaluate the correlation between USG parameters & modified Cormac Lehane grading.Timepoint: 1 day prior to & on the day of surgery—
