[Experience with one-lung anesthesia using balloon catheter for patients with terminal tracheostomy].

We experienced two cases of lung cancer with terminal tracheostomy. Conventional double lumen tubes such as the Broncho-Cath or the Robertshaw were not applicable for one-lung anesthesia for these cases because of anatomical reasons due to the total laryngectomy. One left lower sleeve lobectomy and a right middle lobectomy were performed under one-lung ventilation using an occlusion balloon catheter that was introduced through a seath placed in the spiral type tracheostomy tube through a plastic connector. This method has three advantages: 1) a spiral type tracheostomy tube is easily fitted for the deformed trachea. 2) an occlusion balloon catheter with an extra lumen at its tip enables the airway aspiration and the inflation of the lung. 3) air leakage around a catheter is completely prevented by the use of a catheter introducer. The present method was concluded to be superior to the prior technique with the Forgaty catheter as an endbronchial blocker.
