Design outcomes

Primary

MeasureTime frame
To find out the sensitivity, specificity, positive predictive value and negative predictive value of ultrasonographic airway assessment parameters; Skin soft tissue thickness at level of Hyoid bone, Skin soft tissue thickness at level of vocal cords, distance from skin to epiglottis midway and ratio of the depth of the Pre-Epiglottic space to the distance from the epiglottis to the mid-point of the distance between the vocal cords (E-VC) for predicting a difficult airway.Timepoint: 1.ULtrasound examination of airway will be done before endotracheal intubation 2. Intubation Difficulty score (IDS) assessment will be done during laryngoscopy and intubation—

Secondary

MeasureTime frame
To develop a scoring system for ultrasonographic airway assessment parameters, which best predicts a difficult airway.Timepoint: Scoring system will be developed after analysis of data of all recruited patients—
