Postoperative delirium (POD) is a frequently occurring complication after cardiac surgery. Its occurrence is associated with worse outcomes of patients, including increased morbidity, prolonged hospital stay, increased medical cost, and higher mortality. It is also associated with long-term cognitive decline and decreased quality of life. However, until recently, pharmacological interventions that can effectively prevent its occurrence are still limited. The purpose of this study is to investigate whether perioperative dexmedetomidine use can decrease the incidence of postoperative delirium in patients undergoing cardiac surgery.
