[Tracheotomy in brain injured patients: which patients? Why? When? How?].

The aim of this study is to determine, from the data available in the literature, the indications of tracheostomy in brain injured patients, the incidence and risk factors for complications and the follow-up required until decannulation. The incidence of tracheostomy is 10% in TBI and 50 to 70% in subpopulations with a Glasgow Coma Scale (GCS) below 9. Early complications are not specific. The most frequent late complication is laryngotracheal stenosis, which occurs in 15% and is more frequently observed in the most severe patients with major hypertonia. It is likely that tracheostomy, if needed, should be performed early and the prognosis as to whether it will be required, can be made at the end of the first week. The follow-up of these patients includes surveillance of multiresistant colonisations and systematic performance of fibroscopy before decannulation. Cuffless, small diameters, soft tracheostomy tubes, are preferred on the long-term unless the risk of aspiration remains high.
