Abstract
-
Intraoperative airway obstruction is usually manifested as high peak inflation pressures and decreased exhaled tidal volume. The simultaneous occurrence of increased peak inflation pressure and unchanging plateau pressure generally indicates a mechanical obstruction of the tracheal tube. We experienced a reinforced tube obstruction after intraluminal bulging of the tube. A 59 year-old woman was scheduled for a neck mass excision and ventral hernia repair. The patient was intubated with a 7.0 mm new reinforced tube without any problems. Three hours later, signs of airway obstruction presented, and passage of a suction catheter failed. Examination with the naked eye showed a partial obstruction by intraluminal bulging of the inner layer of the tube. We report this case of partial airway obstruction with a reinforced tube.
