Large airway complications in COVID-19 pneumonia.

COVID-19 pneumonia can cause respiratory failure which requires specialist management. However the inflammatory nature of the condition and the interventions necessary to manage these patients such as endotracheal intubation and tracheostomy can lead to large airway pathology which may go unrecognised. We describe five of the 44 (11%) consecutive patients referred to our specialist ARDS team between April and June 2020 with confirmed COVID-19 pneumonia who developed diverse large airway pathology which comprised of: supraglottic oedema, tracheal tear, tracheal granulation tissue formation, bronchomalacia, and tracheal diverticulum. Large airway pathology may be underappreciated in severely ill patients with COVID-19 pneumonia and should be considered in patients with unexplained air leak, prolonged need for mechanical ventilatory support, and repeated failed extubation or decannulation. If suspected, such patients should be managed by a team with expertise in large airway intervention and early specialist advice should be sought.
