Primary hypothesis: Dexmedetomidine is equal or superior to haloperidol and placebo in the treatment of psychomotor confusion in patients who are recovering from heart surgery.

Study design:

Multi-centre, prospective, randomised, placebo-controlled double-blind study of dexmedetomidine vs. haloperidol for treatment of psychomotor confusion after cardiac surgery. Data will be analyzed in two steps: The primary comparison is between placebo and dexmedetomidine. If the effect of dexmedetomidine is significant, a secondary comparison between dexmedetomidine and haloperidol will follow.
