About this study

If both lungs have relatively equal volumes and the double lumen tube is in a satisfactory position, peak inspiratory pressure between two lungs is similar or equal when each lumen is sequentially clamped while ventilating each lung with the same tidal volume. We are going to investigate a performance of this method by fiberoptic bronchoscopy view and depth of double lumen tube, and compare with an conventional auscultation method.

Treatment and study plan

Pressure difference

Procedure

Peak inspiratory pressures difference between two lungs

Primary outcomes

Fiberoptic bronchoscopy view

Time frame: within 5 min after intubation
- aucsultation under manual ventilation -> fiberopric bronchoscopy view check
- peak inspiratory pressure difference under mechanical ventilation -> fiberoptic bronchoscopy view check

Secondary outcomes

depth of double lumen tube

Time frame: within 5 min after checking fiberopitics
- aucsultation under manual ventilation -> A depth of DLT (incisor)
- peak inspiratory pressure difference under mechanical ventilation -> A depth of DLT (incisor)
