Dexmedetomidine reduces postoperative delirium after joint replacement in elderly patients with mild cognitive impairment
2016
Background and aims
Postoperative delirium (POD) is a common and serious surgical complication among the elderly, especially in those with amnestic mild cognitive impairment (aMCI). Dexmedetomidine (DEX) is neuroprotective for delirium. In this study, we determined the effect of intravenously administered DEX during general anesthesia on POD in elderly aMCI patients undergoing elective hip joint or knee joint or shoulder joint replacement surgery.
