Design outcomes

Primary

MeasureTime frame
During the pre-anaesthetic evaluation airway assessment by 1. Conventional method a. Modified Mallampati (MMP) score b. Thyromental distance (TMD) 2. Ultrasonographic parameters a. Distance from skin to epiglottis (DSE) b. Hyomental distance ratio (HMDR) Induction of anaesthesia direct laryngoscopy will be done and Cormackâ??Lehane (CL) grade will be noted.Timepoint: 1. At the time of pre-anaesthetic evaluation airway assessment. 2. At the time induction of anaesthesia direct laryngoscopy will be done and Cormackâ??Lehane (CL) grade will be noted.—

Secondary

MeasureTime frame
1. ASA Grade- American society of anaesthesiologist classification of physical health 2. BMI-Basic metabolic index 3. Association between demographic variables and Cormac-Lehane Grading. Timepoint: 1. At the time of pre-anaesthetic evaluation airway assessment. 2. At the time induction of anaesthesia direct laryngoscopy will be done and Cormackâ??Lehane (CL) grade will be noted. 3. At the time of statistical data analysis.—
