Study design
dislocation
A total of 148 patients who needed to insert a DLT and changed their position were selected and randomly divided into the perioral adhesive tape fixation group and the non-fixation group. The dislocation and misalignment of the bronchial cuffed end of the DLT were observed after the position of the two groups changed from horizontal to lateral position, so as to evaluate the preventive effect of non-perioral adhesive tape fixation on the dislocation of the bronchial cuffed end of the DLT. See Study design drawing.
