Electrodissection Tonsillectomy With Laryngeal Mask

Oropharyngeal oxygen and volatile anesthetic agent concentration during the use of laryngeal mask airway in children

“…When compared with an ETT, placement of a laryngeal mask airway is generally easier, obviates the need for direct laryngoscopy, and may be associated with lesser airway trauma and subglottic complications during the postoperative course. The reported applications of the laryngeal mask airway now include surgical in the oropharynx such as the adenotonsillectomy .…”

“…Despite these advantages, the laryngeal mask airway may not seal the airway as well as a cuffed ETT, thereby allowing for contamination of the oropharynx with anesthetic gases and oxygen . Aside from the concern about exposure of healthcare providers to anesthetic gases, contamination of the oropharynx with a high concentration of oxygen may pose an increased risk of airway fire.…”
