Design outcomes

Primary

Measure	Time frame
Comparing the difference in oropharyngeal leak pressure with changes in head and neck positions using the LMA Protector airway deviceTimepoint: After induction and 5minutes after neutral head position,5minutes after flexion head position,5minutes after extension head position,5minutes after right lateral position and 5minutes after left lateral head position.	—

Secondary

Measure	Time frame
1.To study the insertion time of LMA Protector 2.To study the number of attempt required for insertion 3.To study the ease of insertion of the device 4.To study hemodynamic variations in different head & neck positions 5.To study fiberoptic assessment of glottic view through the device. 6.To study post-operative complications such as sore throat, stridor or hoarseness, dental trauma, any other relevant complications.Timepoint: 1.After insertion of LMA device 2.After insertion of LMA device 3.After indertion of LMA device 4.5minutes after each head position flexion,extension,neutral,right lateral,left lateral head position 5.30 minutes after insertion of LMA device 6.Immediately after removal of LMA tube to 48 hours after removal to tube	—
