Carinal resection with two high-frequency jet ventilation delivery systems.

A 76-yr-old man underwent carinal resection for squamous cell carcinoma through the right posterolateral thoracotomy approach. Ventilation was maintained by the use of two high-frequency jet ventilators, each attached to a separate catheter during the time of resection and reconstruction of the tracheal carina. These catheters were introduced through the endotracheal tube and positioned into the left and right main bronchi at the beginning of the tracheal resection. Then, conventional ventilation was replaced by high-frequency jet ventilation (HFJV) with different ventilatory variables for each lung. During two-lung jet ventilation there was good oxygenation, normocapnia and no cardiovascular complications. The principle advantage of using two separate high-frequency ventilators is that it allows for maximum ventilatory efficiency with lungs of different compliance.
