Tracheal flap after percutaneous dilatational tracheotomy

摘要

The incidence of granulomas and other posttracheotomy obstructive lesions ranges from 1.5% to 56%, depending on the criteria for examination (surveillance vs. obstructive symptoms). ~ Unlike cicatri-tial stenosis, granulomas and flaps can be effectively removed during rigid bronchoscopy after coagulation with laser or argon-plasma.General anesthesia with adequate muscle relaxation before intubation with the rigid scope is regarded as essential to avoid airway injury, and spontaneous-assisted or jet ventilation are the preferred methods to limit the risk of hypoxia and hypercapnia.
