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.

This study aimed to evaluate the effects on the dislocation and misalignment of the cuffed end of a double-lumen endobronchial tube (DLT) when a patient moves from a horizontal to a lateral position without fixation. A total of 148 patients who had undergone video-assisted thoracoscope surgery were enrolled and randomly divided into two groups: a group in which the periportal end of the DLT was fixed with tape (group I; After lateral position, the dislocation rate of group I and group II was 44.6% and 20.2%, and the misalignment rate was 27.0% and 8.1%, respectively, the incidence of dislocation and misalignment was significantly lower in group II than in group I after the change to a lateral position ( A DLT without periportal fixation is less likely to be displaced and poorly aligned when the patient moves from a horizontal to a lateral position, which could facilitate intra-operative management and reduce the incidence of postoperative complications. 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.
