Maintenance of bronchopulmonary hygiene is mandatory for preventing complications of respiratory therapy in the hospitalized patient. Removal of secretions from the tracheobronchial tree is crucial. Conventional therapy, designed to assist in dislodging airway secretions, includes chest physical therapy, incentive spirometry, transnasal endotracheal suctioning and bronchoscopy. Minitracheostomy was first described by Matthews and Hopkinson for recurrent endotracheal suctioning in 1984. Since then there have been few papers about it, but they report good results with low morbidity. Despite this, its use is not popular in routine clinical work. We report our experience with minitracheostomy in the prevention of sputum retention. We conclude that its use is easy, safe and very effective in preventing postoperative and post-traumatic respiratory complications.
