An unanticipated complication of a novel approach to airway management.

Background: The King LT (King Systems Corporation, Noblesville, IN) is a rescue airway device that is gaining favor in the pre-hospital setting. Unlike other rescue airway devices, such as intubating laryngeal mask airways, the King LT does not allow for the placement of an endotracheal tube through the device. Emergency physicians who receive patients with the King LT in place will be presented with the challenge of converting to a definitive airway.
