Trial ID or NCT#
The purpose of this study is to determine whether the use of dexmedetomidine, a selective α2-adrenergic receptor agonist with sedative, analgesic, and antinociceptive properties, would be associated with a lower incidence of delirium when compared to propofol and midazolam. We hypothesize that sedation with dexmedetomidine following cardiac surgery with CPB will be associated with a lower incidence of postoperative delirium.
