Design outcomes

Primary

MeasureTime frame
Sensitivity, specificity, PPV, NPV and AUROC of USG measured airway parameters (HMDN, HMDE/HMDN, HMDR/HMDN, DSE, TT) in determining difficult direct laryngoscopy. Timepoint: After performing the direct laryngoscopy—

Secondary

MeasureTime frame
1. Sensitivity, specificity, PPV, NPV & AUROC of USG measured airway parameters (DSE, TT) in predicting difficult mask ventilation. 2. Mean Standard Deviation (SD) cut off values of USG measured airway parameters (DSE, TT) in predicting difficult mask ventilation. 3. Mean SD cut off values of USG measured airway parameters (HMDN, HMDE/HMDN, HMDR/HMDN, DSE, TT) in predicting difficult direct laryngoscopy. Timepoint: After performing the direct laryngoscopy—
