A Randomized Non Crossover Study of the GuardianTM Versus SupremeTM Laryngeal Mask Airway

A Randomized Non Crossover Study of the GuardianTM Versus SupremeTM Laryngeal Mask Airway

The investigators test the hypothesis that ease of insertion, oropharyngeal leak pressure, fiberoptic position and ease of gastric tube placement differ between the GuardianTM and the LMA SupremeTM in paralyzed, anesthetized patients.

The GuardianTM is a new extraglottic airway device which brings together features of both the LMA ProSealTM (high seal cuff, gastric access and bite block - to facilitate ventilation, airway protection and airway obstruction, respectively) and the LMA UniqueTM (single use - prevention of disease transmission). In the following randomized, non-crossover study, the investigators test the hypothesis that ease of insertion, oropharyngeal leak pressure, fiberoptic position and ease of gastric tube placement differ between the GuardianTM and the LMA SupremeTM in paralyzed, anesthetized patients.
