Sodium-glucose cotransporter-2 inhibitors: an overview and perioperative implications

Purpose of review Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a relatively new class of drugs used in the management of diabetes mellitus. This review will highlight key pharmacologic characteristics of this class of drugs; discuss their potential role in management of patients with cardiac disease; and raise several perioperative concerns for anesthesiologists caring for patients on SGLT-2 inhibitors. Recent findings Recent trials have shown a strong mortality benefit in diabetic patients on SGLT 2 inhibitors especially in patients with a high cardiovascular burden. In addition, there is a reduction in HbA1c levels, blood pressure, weight and readmissions secondary to heart failure in this patient population. However, these drugs have been also associated with an increased incidence of adverse events, such as euglycemic ketoacidosis, urinary tract infections, acute kidney injury and limb amputations. Summary SGLT 2 inhibitors are being increasingly prescribed secondary to their significant salutatory effect in patients with type II diabetes mellitus. Although there are no perioperative consensus guidelines for management of patients on SGLT2 inhibitors, they should be discontinued at least 24–48 h prior to major surgeries. Their overall management in the perioperative period should be carried out on a case-to-case basis using a multidisciplinary approach.
