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 The laryngeal mask airway Supreme is a newer version of the laryngeal mask airway.
