Brief Summary:
The LMA Supreme is a new extraglottic airway device which brings together features of the LMA ProSeal, Fastrach and Unique. We test the hypothesis that ease of insertion, oropharyngeal leak pressure, fiberoptic position and ease of gastric tube placement differ between the LMA ProSeal and the LMA Supreme in paralyzed anesthetized patients

Condition or disease Intervention/treatment Phase
Paralysis Device: LMA Supreme Device: LMA ProSeal Not Applicable

Detailed Description:
The LMA Supreme is a new extraglottic airway device which brings together features of both the LMA ProSeal (high seal cuff, gastric access and bite block - to facilitate ventilation, airway protection and airway obstruction, respectively), the LMA Fastrach (fixed cuve tube and guiding handle - to facilitate insertion and fixation) and the LMA Unique (single use - prevention of disease transmission). The new features are that the airway tube incorporates a drain tube within its lumen to shorten and straighten its path, it is oval-shaped to match the shape of the mouth and to reduce rotation in the pharynx, the inner cuff has been strengthened to prevent airway obstruction from infolding and epiglottic fins have been added to prevent airway obstruction from epiglottic downfolding. In the following randomized, crossover study, we test the hypothesis that ease of insertion, oropharyngeal leak pressure, fiberoptic position and ease of gastric tube placement differ between the LMA ProSeal and the LMA Supreme in paralyzed, anesthetized patients
