Endotracheal tube with movable blocker to prevent aspiration of intratracheal bleeding.
A newly developed endotracheal tube with a movable blocker was found to be lifesaving in patients with copious and persistent intratracheal bleeding. The cases of 4 patients are presented. In 3 patients, severe intratracheal bleeding was attributed to the extensive bronchopulmonary laceration caused by blunt chest trauma. In the remaining patient, the bleeding was due to rupture of the sutured site in the right pulmonary artery; the rupture was caused by a postoperative bronchopleural fistula. In these patients, spread of blood was completely prevented and pulmonary resection was performed safely by using the blocker in this new device.
