Cuffed tube tracheostomy in the dog.

A surgical technique of performing tracheostomy in dogs requiring prolonged intubation with either cuffed or uncuffed tubes is described. Cannulae used in humans are anatomically unsuitable for the dog. The cannula and cuff described in this paper did not predispose to severe mechanical trauma to the trachea and we attempted to minimize factors that may predispose to tracheal damage during the period of intubation and the subsequent development of late tracheal injuring after extubation. A simple method of humidification in these healthy dogs proved adequate; neither tenacious tracheobronchial secretion nor the retention of secretions were seen.
