Ventilation strategy and anesthesia management in patients with severe tracheal stenosis undergoing urgent tracheal stenting.

Establishment of effective airway ventilation in patients with severe tracheal stenosis should be based on the cause, location, and severity of tracheal narrowing. Veno- arterial ECMO may be considered in patients with severe stenosis, if they are judged unable to tolerate conventional ventilation or jet ventilation.
