Determination of DLT bronchial cuffed end dislocation
Before intubation, a mark (L 0.5) was made on the DLT at 0.5 cm from the upper edge of the bronchial capsule. The patient was moved from a horizontal to a lateral position 10 min after double-lumen endobronchial intubation, as required for the surgery, at which time fiberoptic bronchoscopy was performed again and the position of the DLT determined. The DLT’s position was adjusted so that the L 0.5 line was level with the carinal in the normal position. If the position deviation exceeded 0.5 cm, the DLT was judged to be dislocated at the bronchial cuffed end [
