Successful use of an EZ-blocker for lung isolation and management in a hemoptysis patient

When massive hemoptysis develops suddenly, patients typically die due to hypovolemia or airway obstruction. Intubation, endobronchial blocking, and elimination of blood clots are urgently required. However, existing double-lumen tubes and single endobronchial balloon systems are inadequate. We herein report successful EZ-blocker-mediated one-lung ventilation of a patient with a massive hemoptysis who required emergency life-saving surgery.
