[Thoracoscopic surgery using a new bronchial blocker].

We report use of a new bronchial blocker through a single-lumen endotracheal tube to achieve one-lung ventilation to perform thoracoscopic operation in patients in whom placement of the double-lumen tube failed and difficult intubation is predicted. The bronchial blocker tube was placed into the aimed bronchus under the bronchoscopic vision and the cuff of the blocker was inflated to achieve one-lung ventilation. In all of the 4 patients, the bronchial blocker could be inserted and placed safely, quickly, and exactly under the fiberoptic flexible bronchoscopic vision to perform thoracoscopic operation without any complications. The new bronchial blocker tube through the indwelling endotracheal tube may have advantages in situations where placement of double-lumen endotracheal tubes is technically impossible or inappropriate. The use of the new bronchial blocker tube will, however, require careful evaluation in larger series.
