  Purpose

Laryngeal mask airway is a widely used device in routine anesthesia for airway management during surgery. It consists of a tube with an inflatable cuff that is inserted into the mouth after induction of general anesthesia. The Proseal Laryngeal mask airway and the Laryngeal mask airway Supreme are two variants of the Laryngeal mask airway. The laryngeal mask airway Supreme is a newer version of the laryngeal mask airway.

The research is being done to compare two variants of the laryngeal mask airway: the Proseal laryngeal mask airway and the Laryngeal mask airway Supreme. This study will determine if the newer model, the Laryngeal mask airway Supreme, is easier to insert and is better positioned than the older model, the Proseal laryngeal mask airway. Both models are approved for use by the FDA, and are routinely used to assure the airway during general anesthesia.

Arms Assigned Interventions
Supreme LMA

Supreme Laryngeal mask airway is a new, single use laryngeal mask airway variant.

The choice of the airway device will be randomized by opening a sealed envelope immediately before induction. Both airway devices will be blindly inserted by an experienced attending anesthesiologist.

Device: Supreme Laryngeal mask airway
Supreme Laryngeal mask airway is a new, single use laryngeal mask airway variant
Device: Proseal laryngeal mask airway
Proseal is a multiple use, variant of the laryngeal mask airway
Active Comparator: Proseal LMA

Proseal is a multiple use, variant of the laryngeal mask airway.

The choice of the airway device will be randomized by opening a sealed envelope immediately before induction. Both airway devices will be blindly inserted by an experienced attending anesthesiologist.
