Design outcomes

Primary

Measure	Time frame
Incidence and severity of postoperative sore throat or pharyngodyniaTimepoint: 1 hr after Supraglottic airway device removal	—

Secondary

Measure	Time frame
Oropharyngeal leak PressureTimepoint: After successful supraglottic airway device insertion;To compare the insertion time and number of attempts required for insertion between the two groupsTimepoint: 3 Minutes after induction;To compare change in intracuff pressureTimepoint: after induction, 5 minutes after pneumoperitoneum, 5 minutes after stopping pneumoperitoneum and at the end of surgery;3. To compare respiratory mechanics peak airway pressure (Ppeak), plateau airway pressure (Pplat), PEEP, set TV (TV set), actual TV (TV act)Timepoint: after induction, 5 minutes after pneumoperitoneum, 5 minutes after stopping pneumoperitoneum and at the end of surgery;To compare dysphagia and post operative nausea vomiting between the two groups. Timepoint: 1 hr after surgery	—
