Observational: LMA Supreme
An appropriately sized LMA Supreme will be prepared by removing all air from the cuff while applying manual pressure. A water soluble non-local anesthetic containing lubricant gel will be applied to the fully deflated airway before insertion. A 1 cm column of the gel will be preloaded into the gastric port of the LMA Supreme for the Gel Test.
The cuff will be inflated with a manometer to a pressure of approximately 30cm H2O. If a significant leak is detected, the cuff will be inflated in increments of 5cm H2O until a satisfactory seal is obtained. The final cuff pressure will be recorded. The lungs will then be gently inflated by applying manual pressure to the anesthesia circuit bag while observing the gel column in the LMA Supreme gastric port for movement.
