Brief Summary:
The purpose of the study is to determine whether dexmedetomidine is a more effective medication than haloperidol in the treatment of agitation and delirium in patients receiving mechanical ventilation in an intensive care unit Haloperidol is a medication conventionally used for this purpose
The investigators will study only patients who have recovered from their illness to the point that were it not for agitation and delirium they would no longer require mechanical ventilation
The investigators hypothesize that patients receiving dexmedetomidine will be able to discontinue mechanical ventilation earlier than those receiving haloperidol

Detailed Description:
Up to 80 of patients undergoing intensive care have delirium Early in the ICU stay delirium and agitation are usually prevented using analgesic and sedative drugs which essentially render the patient unconscious This is appropriate in the context of aggressive treatment of pathophysiological instability which often requires multiple painful procedures However after the underlying pathophysiological problem has resolved patients sometimes remain delirious and agitated This often requires ongoing heavy sedation which in turn necessitates continued mechanical ventilation and can worsen the temporarily masked delirium Prolonged mechanical ventilation increases the risk of ventilator associated pneumonia and other life threatening complications
The drug most commonly used to treat delirium is haloperidol which reduces hallucinations and unstructured thought patterns but also reduces the interaction with the environment Haloperidol has significant side effects including extrapyramidal reactions in 1-10 of patients neuroleptic malignant syndrome in which it is the cause in 50 of cases and prolonged QT syndrome which can precipitate fatal arrhythmias
An ideal sedative agent in this context would have fewer side effects relieve agitation without causing excessive sedation and be easily titrated An analgesic action might allow less opioid use also lessening delirium Early studies in other contexts suggest dexmedetomidine has all these properties
The investigators hypothesise that patients with ICU-associated delirium after the resolution of their underlying pathological process who receive dexmedetomidine will be able to be extubated earlier than those who receive haloperidol
