When the end is really the end? The extubation in the difficult airway patient.

Difficult airway management remains one of the most important sources of anesthesia related accidents; recent reviews and dedicated guidelines suggest that not only intubation, but extubation too is a critical phase in terms of potential accidents and serious complications. This paper will highlight some fundamental concepts regarding extubation related problems, focusing particularly on epidemiology, risk factors and time course of difficult extubation, suggesting some conceptual points to plan and manage patients in which a difficult extubation might be expected, including parameters and test to be performed to assess and predict such a situation.
