Diabetic patients with fractures can have surgery, but they need to keep their blood glucose within a certain range (between 7.8 and 10 mmol/L). For diabetic patients, wounds caused by fracture surgery are prone to infection and delayed wound healing due to their high blood glucose levels. Fracture surgery, which may cause a stressful increase in blood glucose, can result in a significant increase in blood glucose if glycemic control is poor. The recommended glycemic control goal for most perioperative diabetic patients is 7.8 to 10.0 mmol/L. For a few patients, such as those with a low risk of hypoglycemia, those who are proposed to undergo cardiac surgery, and those who are undergoing other delicate surgeries, a more stringent glycemic control goal of 6.1 to 7.8 mmol/L may be recommended. For patients with serious comorbidities or high risk of hypoglycemia, the glycemic control goal can be relaxed to 10.0~13.9mmol/L. Diabetic patients can have fracture surgery, but they need to follow the doctor’s instructions for glycemic control and standardized treatment.
