RESUMO
We experienced 22 consecutive anaesthetic managements requiring one-lung ventilation for thoracotomy. We used our original connector, which enabled us to insert a bronchial blocker cut from Univent tube and fibreoptic bronchoscope into the single lumen tracheal tube without air leakage and instability. The bronchial blocker was easily introduced into the mainstem bronchus of the non-dependent lung. The pulmonary alveoli were well collapsed through air-vent inside the bronchial blocker, and we could offer good surgical field. When one-lung ventilation was finished during surgery, we removed the bronchial blocker with connector, and could insert a larger fibreoptic bronchoscope and a suction catheter into the single lumen tracheal tube. We could detach or exchange the bronchial blocker, when they are not functioning well. This method was excellent in the airway management for usual thoracotomy.
