[Expert consensus on the clinical application of intravenous insulin infusion (2026 edition)].

Intravenous insulin infusion remains a cornerstone of clinical glycemic management. It is extensively utilized across diverse multidisciplinary settings, including hyperglycemic crises, the perioperative period, critical illness, and nutritional support. Standardizing intravenous insulin infusion protocols across various clinical departments is essential for improving the overall prognosis of patients with diabetes and its associated comorbidities. Initiated by the National Clinical Research Center for Endocrine and Metabolic Diseases (Changsha), the National Diabetes Prevention & Control Center (DPCC), and the Diabetes Society of China National Health Association, the "Expert Consensus on the Clinical Application of Intravenous Insulin Infusion (2026 edition)" was developed through the collaborative efforts of experts in endocrinology, cardiology, general medicine, emergency medicine, critical care, nursing, and clinical pharmacy. By integrating multidisciplinary efforts, and in accordance with the standards and procedures of the grading of recommendations, development and evaluation (GRADE) system, 7 clinical questions and 9 recommendations were proposed regarding the clinical application of intravenous insulin infusion, including its clinical indications, operating procedures, precautions, and other relevant aspects. Its implementation aims to bridge the gap in clinical practice between endocrine and non-endocrine departments (including surgical and primary care units), thereby enhancing the standardization of intravenous insulin infusion and ultimately improving the overall therapeutic outcomes and prognosis for patients with diabetes and related metabolic disorders.
