Non-Crossover Study of the LMA Protector Versus Ambu AuraGain

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