Various causes of endotracheal tube obstruction during general anesthesia exist. Herein, the case of a 77-year old male patient, with tracheal deviation, who was intubated with an endotracheal tube in the emergency room, without a Murphy eye, is reported. He was transferred to the operating room for the removal of a subdural hematoma. The endotracheal tube suddenly became obstructed during flexion of neck for the craniotomy procedure. The distal bevel of the endotracheal tube, without Murphy eye, was discovered to have come into contact with the tracheal wall, with the airway being obstructed during the fiberoptic bronchoscopy. Shortly after extubation of the obstructed tube, an armored tube, with a Murphy eye, was reintubated, after which the respiration pattern immediately returned to normal.
Key Words: endotracheal tube obstruction; Murphy eye; tracheal deviation
