title: How to decannulate tracheostomised severe head trauma patients: a comparison of gradual vs abrupt technique.
abstract: Tracheostomy is a common surgical procedure performed in patients with severe head injury to facilitate prolonged airway and ventilatory support. Decannulation is the procedure of removing the tracheostomy tube either gradually by downsizing the tube or abruptly in a single sitting. This prospective study was done to evaluate gradual vs abrupt techniques for successful decannulation in tracheostomised severe head trauma patients in Post Graduate Institute of Medical Education and Research (PGIMER), a central government tertiary centre in Chandigarh, India. A total of 118 patients, recruited over one and half years duration were arbitrarily divided into 2 groups: Gradual and Abrupt. Particulars were taken. Time since tracheostomy, timing of decannulation, Glasgow Coma Scale, amount of secretions, breath holding time, CXR and STN radiographs and cough reflex were all assessed. Follow up was done at one month to classify those who were re-tracheostomised or re-intubated as decannulation failures. Sixty-eight patients were decannulated gradually and 50 abruptly. Of the various factors assessed, only cough reflex, number of suctioning required per day, X-ray STN and use of antibiotics for more than 7 days were found to be statistically significant. One hundred and fourteen patients, 67 out of 68 in the GD group and 47 out of 50 in the AD group, had successful outcome. The study showed that success or failure of decannulation is independent of mode of decannulation.
