Primary Outcome Measures

Name	Time	Method
1. POGO score <br/ ><br>The percentage of glottic opening (POGO) score corresponds to the percentage of the glottis visualized during laryngoscopy. A 100% value denotes visualization of the entire glottis from the anterior commissure of the vocal cords to the inter-arytenoid notch. If none of the glottic opening is visualised , then the value is stated as 0%. Percentage of view of the glottic opening between 0-100% will be noted according to the view obtained with VL in each group. <br/ ><br>Timepoint: The percentage of glottic opening (POGO) score shall be recorded in supine head flat position followed by head elevation of 4cm,6m and 8cm after induction of anaesthesia.
