Double-lumen tube for ventilation in severe kyphoscoliosis

The presence of kyphoscoliosis can adversely affect gas exchange because of restriction to gas flow and reduction of lung volume. The effects become more exaggerated during positive-pressure ventilation due to the uneven distribution of ventilation. The use of a double-lumen tube helps to reduce the ventilation perfusion mismatch that occurs because of positive-pressure ventilation. We report a patient with severe kyphoscoliosis who underwent repair of an atrial septal defect, in whom a double-lumen tube was used for ventilation and the conduct of general anesthesia.
