简要总结
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.
详细描述
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.
