Treatment and study plan

The cuff of endotracheal and endobronchial is collapsed

Device

The diameter of double-lumen tube at the cuff of endotracheal and endobronchial when the cuff is collapsed as the diameter of double-lumen tube and select a double-lumen tube that matches the patient's trachea and bronchial innerdiameter based on this diameter

The cuff of endotracheal and endobronchial is inflated

Device

The diameter of double-lumen tube at the cuff of endotracheal and endobronchial when the cuff is inflated as the diameter of double-lumen tube and select a double-lumen tube that matches the patient's trachea and bronchial innerdiameter based on this diameter

Primary outcomes
