Conclusion
airway mucosal injury, dislocation
POSTOPERATIVE COMPLICATIONS
The present study found that not fixing the periportal end of the DLT is less likely to cause dislocation and misalignment of the bronchial cuffed end when moving the patient from a horizontal to a lateral position. It is also less likely to influence hemodynamics and cause airway mucosal injury, which makes it more conducive to intraoperative anesthesia management and the reduction in incidence of postoperative complications.
