A method for addressing right upper lobe obstruction with right-sided double-lumen endobronchial tubes during surgery: a randomized controlled trial

摘要

BackgroundA right-sided double-lumen tube (R-DLT) tends to obstruct the right upper lobe intraoperatively due to anatomical distortion during surgery. If the R-DLT is poorly matched with the patient’s airway anatomy, it will not be possible to correctly replace the tube with a fiberoptic bronchoscope (FOB). In our study, we aimed to explore an efficient method for difficult repositioning caused by right upper lobe occlusion during surgery: repositioning the R-DLT from the right main bronchus into the left main bronchus. The current study was designed to assess the efficacy and safety of this method.
