Design outcomes

Primary

MeasureTime frame
To correlate Thyromental height test with ease of direct laryngeal visualization as assessed by Cormack-Lehane grading.. Timepoint: Difficulties in visualization of the vocal cords during laryngoscopy and intubation, usually graded as Cormack &Lehane grade III and IV and classified as ââ?¬Å?difficultââ?¬? Grade I: Full view of the glottis. Grade IIa: Partial view of the glottis is visible. Grade IIb:Arytenoids or posterior part of the vocal cords only just visible. Grade III: Only epiglottis is visible. Grade IV: No glottis structures visible .—

Secondary

MeasureTime frame
To correlate clinically mallampati grading, sternomental distance, thyromental distance with direct laryngeal visualization as assessed by Cormack Lehane grading. 2.To assess time taken for endotracheal intubation. 3.To correlate TMHT with the incidence of difficult intubation. Timepoint: Difficulties in visualization of the vocal cords during laryngoscopy and intubation, usually graded as Cormack &Lehane grade III and IV and classified as ââ?¬Å?difficultââ?¬? Grade I: Full view of the glottis. Grade IIa: Partial view of the glottis is visible. Grade IIb:Arytenoids or posterior part of the vocal cords only just visible. Grade III: Only epiglottis is visible. Grade IV: No glottis structures visible .—
