Disconnection technique
The double lumen tube is introduced into the glottis under direct laryngoscopy. After the bronchial cuff had passes the vocal cords, the tube is rotated counterclockwise 90° and advanced until a slight resistance was encountered. One lung ventilation is initiated after the lumen of operative lung is clamped and opened.
The brochial blocker (BB) is introduced through the endotracheal tube to the desired bronchus under fiberoptic bronchoscopy (FOB) vision by turning the device's steering wheel. The BB cuff is inflated with air under FOB vision with the volume necessary to seal the bronchus and initiate one lung ventilation. And then, dependent lung is ventilated.
Disconnection technique; 1) before initiating OLV, we turned-off the ventilator and fully opened the adjustable pressure limiting valve allowing both lungs to collapse, and 2) after loss of the carbon dioxide trace on the capnograph, 3) inflated the BB cuff with air, and 4) turned-on the ventilator allowing only dependent-lung reventilation.
