Design outcomes

Primary

MeasureTime frame
To compare thyromental height (TMH) and sonographic hyomental distance ratio (HMDR) in predicting difficult endotracheal intubation in adults undergoing elective surgery under general anaesthesia.Timepoint: Thyromental height and Sonographic hyomental distance ratio will be measured preoperatively. Intraoperatively, Cormack Lehane grading and Percentage of glottic opening scoring will be done.—

Secondary

MeasureTime frame
To compare these two tests viz thyromental height and sonographic hyomental distance ratio with other established tests of airway assessment viz: modified Mallampatti test (MMT), thyromental distance (TMD) and sternomental distance (SMD).Timepoint: The established tests of airway assessment viz: modified Mallampatti test (MMT), thyromental distance (TMD) and sternomental distance (SMD) will be assessed in the preoperative setting.—
