Fracture of tracheostomy tubes. Pathogenesis and prevention.

The literature relating to fractured tracheostomy tubes is reviewed and a further case reported. The factors which are known to predispose to this accident include the materials used in the manufacture of the tracheostomy tube and the actual manufacturing processes. Others are the chemical processes which result from the prolonged contact of the tracheostomy tube with respiratory secretions, the methods employed in the care and re-sterilization of the tubes, and the ageing and deterioration that result from prolonged usage. Some preventative measures are suggested.
