Trial Title: A Comparison of Dexmedetomidine and Haloperidol in Patients With Intensive Care Unit (ICU)-Associated Agitation and Delirium

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Patients will be eligible for the study if, in the opinion of the treating clinician, they continue to require mechanical ventilation only because their degree of agitation requires such a high dose of sedative medication (midazolam or propofol, the only commonly used specific sedatives in our unit) that extubation is not possible.~Exclusion Criteria:~* Patients who could not be extubated even if delirium or agitation were corrected. This will include:~  * Patients receiving high dose opioid analgesia (\>20 m/morphine/day)~ * Patients shortly to return to the operating theatre~ * Patients undergoing repeated invasive procedures, in whom it is desirable to maintain deep sedation.~ * Patients likely to require ongoing airway protection or control, or ventilatory support (for example, spinal patients with an inadequate vital capacity)~* Known allergy to haloperidol or alpha2 agonists
