Overview
Brief Summary
The purpose of this study is to determine whether the leak pressure of the recently introduced laryngeal mask airway, Ambu AuraGain performs superior to the established laryngeal mask LMA Supreme in surgical patients undergoing general anesthesia. This leak pressure is the pressure at which a gas leaks around the airway, which is a key marker of efficacy and safety of its use; a higher leak pressure suggests a better seal between the artificial airway and patient's airway.

Outcomes
Primary Outcomes
Oropharyngeal leak pressure (OLP) for each airway device after insertion
Time Frame: Within 2-3 minutes after laryngeal mask insertion before start of surgery.
OLP is defined as 'the anesthesia circuit pressure at which a gas leak occurs around the SAD'.
Secondary Outcomes
- Satisfaction of patient and the anesthesiologist with the device(After 1hr in the post anesthesia care unit (PACU))
- Postoperative nausea and vomiting (PONV)(at 1 hr, 2hr and 24 hrs after the surgery)
- Phrayngolaryngeal complications(at 1 hr, 2hr and 24 hrs after the surgery)
