Ventilation through an extraglottic tracheal tube: a technique for deep extubation and airway control

Editor—Tracheal extubation after general anesthesia is a critical event of an anaesthetic, probably more important than induction and intubation of the airway; minor complications can result in significant morbidity and even mortality.¹² Both the Fourth National Audit Project and the ASA closed claims analysis reported complications from extubation.³⁴ The Difficult Airway Society developed a systematic approach to anticipated easy extubations and to those deemed difficult. Asleep extubation (commonly referred to as deep extubation), as opposed to awake extubation, is in a different arm of the Difficult Airway Society algorithm from the easy airway extubation.⁵
