Anaesthesia and tracheobronchial stenting for central airway obstruction in adults Conacher IDBr J Anaesth 2003[Mar]; 90 (3): 367-74In the last decade, stents suitable for the management of tracheobronchial stenoses and obstruction have evolved from bulky prostheses requiring tracheal resection to small devices that are self-expanding and can be inserted using fibreoptic techniques. The experience base for this review is more than 100 patients between 1989 and 2001 who have been anaesthetized for stent insertion. Early cases required rigid bronchoscopy for the routine of insertion. Anaesthetic techniques have evolved from those that were designed and developed for laser surgery in the central airways. The advent of modern devices now extends the variety of anaesthetic management techniques that can be used. But the original one, based on the requirement for use of a rigid bronchoscope, is best for dealing with complications and extracting problem stents. The most frequent complication of the processes of stent insertion has been respiratory failure because of carbon dioxide retention, consequent on obstruction with secretions in the area of the carina. The nature of central airway problems suggests that anaesthesia induction, management and teaching should not be founded on the conventional model-base of upper airway obstruction.|*Stents/adverse effects[MESH]|Adult[MESH]|Airway Obstruction/*therapy[MESH]|Anesthesia/*methods[MESH]|Bronchial Diseases/diagnostic imaging/therapy[MESH]|Bronchoscopy/methods[MESH]|Constriction, Pathologic/therapy[MESH]|Equipment Design[MESH]|Humans[MESH]|Intubation, Intratracheal/methods[MESH]|Laryngeal Masks[MESH]|Postoperative Complications/therapy[MESH]|Preoperative Care/methods[MESH]|Radiography[MESH]|Tracheal Stenosis/diagnostic imaging/therapy[MESH] |
