Delirium is a frequent postoperative complication in elderly patients after non-cardiac surgery. We performed this updated meta-analysis to ascertain more precisely the efficacy of dexmedetomidine (DEX) on the incidence of postoperative delirium (POD) in elderly patients after non-cardiac surgery. ⋯ Perioperative dexmedetomidine reduces the incidence of POD in elderly patients after non-cardiac surgery, but this comes at the cost of an increased incidence of hypotension and bradycardia.
