Clinical Trial Summary

The purpose of this study is to investigate a performance of initial positioning of left sided double lumen endobronchial tubes using peak inspiratory pressures difference between two lungs.


Description:

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.

Type Measure Description Time frame Safety issue
Primary Fiberoptic bronchoscopy view aucsultation under manual ventilation -> fiberopric bronchoscopy view check
peak inspiratory pressure difference under mechanical ventilation -> fiberoptic bronchoscopy view check
within 5 min after intubation
Secondary depth of double lumen tube aucsultation under manual ventilation -> A depth of DLT (incisor)
peak inspiratory pressure difference under mechanical ventilation -> A depth of DLT (incisor)
within 5 min after checking fiberopitics
