[Complications of tracheostomy in patients with severe motor and intellectual disabilities and their management].
Some patient with severe motor and intellectual disabilities have a narrow mediastinum due to severe scoliosis or thoracic deformity. Complication of tracheostomy in these patients, such as granulation of the lower end of the cannula and tracheo-innominate artery fistulae, are difficult to treat. The causes of recurrent respiratory distress after tracheostomy in four patients with severe motor and intellectual disabilities were investigated, and its management was evaluated based on chest CT and bronchoscopy. In all patients, the lower end of the cannula was in contact with the site of tracheal stenosis, accompanied by granulation with arterial pulsation. In three patients, tracheomalacia as a complication of tracheostomy was also noted. In three patients, changing the cannula to fix its lower end proximally to the lesion, combined with stent placement in one patient with tracheomalacia, resulted in regression of the granulation and respiratory distress. However, one patient with severe tracheomalacia, who had been treated by stent placement alone, died of tracheo-innominate artery fistula. To prevent complications of tracheostomy in patients with severe motor and intellectual disabilities, it is important to select cannulas with a suitable length and angle. In the absence of severe tracheomalacia, use of custom-made short cannulas that can be fixed proximally to the site of stenosis and to the proximity of arteries are appropriate for this purpose.
