Sequential lobar-lung-lobar isolation using a deflecting tip bronchial blocker

This case report describes the use of a bronchial blocker (BB) with a wheel-controlled tip (Cohen flexitip endobronchial blocker) to provide initially middle and lower right lobe isolation and then right lung isolation (RLI) during right lower lobectomy in a patient with compromised pulmonary function preoperatively. As predicted, RLI and one-lung ventilation were associated with worsening oxygenation. Toward the end of the surgery, RLI was converted back to middle and lower right lobe isolation and oxygenation returned to normal levels. The BB design made lobar isolation easier and enabled repositioning of the BB during surgery. The techniques used for BB insertion as well as lobar and lung separation are described.
