the tip opening angle to the left: After fixing the position of the tracheal catheter, the opening of the tip of the blocker will be adjusted to left under the guidance of the fiber bronchoscope.
the tip opening angle to the right: After fixing the position of the tracheal catheter, the opening of the tip of the blocker will be adjusted to right under the guidance of the fiber bronchoscope.
Study summary
This trial is a practical, multicenter, prospective, parallel grouping, randomized controlled,two-arm study. This study will be conducted in three centers including the First Hospital of China Medical University, Seoul National University Hospital and the University Clinical Center of Serbia. The investigators aim to investigate the effect of different occlusion angles of disposable tracheal blocker on right one-lung ventilation
