Design outcomes

Primary

Measure	Time frame
Oropharyngeal leak Pressure with head in the neutral, flexed, extended and rotated to left positionTimepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA	—

Secondary

Measure	Time frame
Difference between inspired & expired volumeTimepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA;Difference between leak pressure & airway pressureTimepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA;End tidal CO2Timepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA;Expired tidal volumeTimepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA;failed placement of SADTimepoint: During Insertion, within first 10 mins;Peak airway pressureTimepoint: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA;successful placement in the first attemptTimepoint: During insertion, within first 5 mins;Time to insert SADTimepoint: From taking Laryngeal mask Airway in hand to Obtaining square shaped capnogram on the monitor,within 5 mins	—
