Postop Complication With Euglycemic Diabetic Ketoacidosis in a Patient Receiving Empagliflozin

Abstract

Euglycemic diabetic ketoacidosis (EDKA) is an uncommon diabetic complication with increasing prevalence and is associated with the use of sodium-glucose co-transporter 2 inhibitors (SGLT2i).We report the case of a 77-year-old female patient with type 2 diabetes mellitus, treated with metformin/linagliptin and empagliflozin, who initiated a slurred speech and altered level of consciousness in the postoperative period of a cholecystectomy. On observation, the patient presented with Kussmaul breathing and mucosal dryness and was ketotic. Laboratory exams showed metabolic acidosis with an elevated anion gap, normoglycemia, and positive ketonemia. Fluid replacement with dextrose solution and continuous insulin infusion were initiated, with progressive clinical and laboratory improvement. On discharge, she showed resolution of symptoms, and empagliflozin was discontinued from her usual medication.Despite the warnings of European and American medical agencies in 2015/2016, EDKA remains a challenging diagnosis due to its unspecific and insidious symptoms.
