Does the periportal end of a double-lumen endobronchial tube need to be fixed to prevent dislocation of the cuffed end caused by a change in position? A randomized controlled trial.

Through a randomized controlled trial, this study innovatively found that no double-lumen endobronchial tube (DLT) peripheral tape binding can prevent the dislocation and misalignment of the DLT bronchial cuffed end in patients undergoing thoracic surgery from horizontal to lateral position.
