BACKGROUND: Percutaneous tracheostomy (PT) in patients with coronavirus disease (COVID-19) included several critical steps associated with increased risk of aerosol generation. We reported a modified PT technique aiming to minimize the risk of aerosol generation and to increase the staff safety in COVID-19 patients. METHODS: PT was performed with a modified technique including the use of a smaller endotracheal tube (ETT) cuffed at the carina during the procedure. RESULTS: The modified technique we proposed was successfully performed in three critically ill patients with COVID-19. CONCLUSIONS: In COVID-19 critically ill patients, a modified PT technique, including the use of a smaller ETT cuffed at the carina and fiber-optic bronchoscope inserted between the tube and the inner surface of the trachea, may ensure a better airway management, respiratory function, patient comfort, and great safety for the staff.
