Brief Summary:
The study aims to demonstrate that dexmedetomidine is non-inferior to current best practice sedation with propofol/midazolam and daily sedation stops, in maintaining a target depth of sedation in long-stay intensive care unit (ICU) patients, and that dexmedetomidine, compared with current best practice, reduces the length of ICU stay.

Secondary Outcome Measures :
  1. Nurse's assessment of subject communication
  2. Duration of mechanical ventilation, weaning time and ventilator-free days in ICU
  3. Length of total hospital stay
  4. Functional recovery during hospitalisation
  5. Need for rescue medication to maintain sedation
  6. Frequency of delirium
  7. Frequency of organ failures and failure-free days
  8. Frequency of critical illness polyneuropathy
  9. ICU- and in-hospital survival
  10. Cost of care in the ICU
  11. Total cost of hospitalisation
  12. Blood levels of dexmedetomidine seen with long-term treatment
