Unusual foreign body airway obstruction after laryngeal mask airway insertion

Abstract

Airway obstruction during general anesthesia is fairly common. Foreign body causing obstruction of the laryngeal mask airway is uncommon but can confuse the anesthesiologist trying to troubleshoot the cause of inability to ventilate. We present a case of complete airway obstruction with a nematode caught in the vertical bars of the laryngeal mask airway after its insertion.
