Objective: This study aims to analyze the causes of postoperative transition from euglycemic diabetic ketoacidosis (EDKA) to diabetic ketoacidosis (DKA), summarize clinical nursing experiences, enhance the recognition and management of such complications, and improve patient prognosis. Methods: A detailed case analysis was conducted on a patient who developed EDKA early after breast cancer surgery, which subsequently transitioned to DKA. A multidisciplinary team (MDT) consultation was employed to formulate a personalized nursing plan. Specific methods included comprehensive clinical data collection, monitoring of blood glucose, urine ketones, and blood ketone levels;implementing dynamic insulin adjustment strategies;providing dietary education and psychological support;and guiding dietary adjustments through nutritional consultations. Results: Through personalized observation, blood glucose management, dietary management, psychological care, and wound care, the patient’s blood and urine ketone levels returned to normal, the flap healed well, and blood glucose was maintained within the normal range. The patient is currently undergoing postoperative adjuvant chemotherapy. Conclusion: For postoperative patients with unexplained nausea, vomiting, and dehydration, regardless of diabetes history, timely testing of blood glucose, blood ketones, blood urea nitrogen, creatinine, electrolytes, and blood gas analysis can facilitate early detection of EDKA. Additionally, personalized management of blood glucose, diet, psychological care, and wound care is crucial for the prevention and treatment of EDKA.
