Endotracheal tube obstruction during anesthesia can have many causes. Hyperinflation of the remaining lung after a pneumonectomy can severely displace the trachea, and attachment of an endotracheal tube tip to the wall of a deviated trachea may also cause severe airway obstruction. The right lung of the patient was removed 3 years ago due to lung cancer. Compensatory hyperinflation of the left lung and severe right-sided tracheal deviation was seen on a chest X-ray. An armored endotracheal tube without Murphy's eye was used. Two hours after beginning the operation, peak airway pressure and PETCO2 began to increase gradually. A wheezing-like sound was heard. Bronchospasm was suspected, but signs of a spasm were not relieved by medications. The signs completely disappeared after pulling the tube 2 cm proximal. The position of the tube should be confirmed by fiberoptic bronchoscopy or chest X-ray after intubation when the trachea is deviated.
Key Words: Complications: airway; endotracheal tube obstruction; Equipment: tubes, endotracheal
