Percutaneous dilational tracheostomy.

Tracheostomy is a commonly performed intervention with several benefits in the treatment of patients with chronic respiratory failure. Percutaneous dilational tracheostomy techniques have allowed bedside tracheostomy placement in the modern intensive care unit. Percutaneous dilational tracheostomy can be safely performed by interventional pulmonologists, medical intensive care physicians, and surgical specialists. When performed with the assistance of adjuncts, such as flexible bronchoscopy, the percutaneous dilational method has a favorable complication rate, efficiency, and cost profile compared with surgical tracheostomy.
