AbstractClinicians inevitably encounter patients who meet the diagnostic criteria for the metabolic syndrome (MetS); these criteria include central obesity, hypertension, atherogenic dyslipidaemia, and hyperglycaemia. Regardless of the variations in its definition, MetS may be associated with adverse outcomes in patients undergoing both cardiac and non-cardiac surgery. There is a paucity of data concerning the anaesthetic management of patients with MetS, and only a few observational (mainly retrospective) studies have investigated the association of MetS with perioperative outcomes. In this narrative review, we consider the impact of MetS on the occurrence of perioperative adverse events after cardiac and non-cardiac surgery. Metabolic syndrome has been associated with higher rates of cardiovascular, pulmonary, and renal perioperative events and wound infections compared with patients with a non-MetS profile. Metabolic syndrome has also been related to increased health service costs, prolonged hospital stay, and a greater need for posthospitalization care. Therefore, physicians should be able to recognize the MetS in the perioperative period in order to formulate management strategies that may modify any perianaesthetic and surgical risk. However, further research is needed in this field. © The Author 2015. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. All rights reserved.
