The goal of this multi-center, pragmatic, randomized controlled trial is to assess the effectiveness of continuous glucose monitoring (CGM) compared with conventional monitoring in enhancing surgical outcomes for diabetic patients. The main questions it aims to answer are:
* To assess the effectiveness of CGM compared with conventional monitoring in reducing the comprehensive complication index (CCI) for patients with diabetes or impaired glucose tolerance (IGT) within 30 days after surgery. * To analyze the impact of different age groups, types of surgery, preoperative levels of HbA1c, and preoperative 24h glycemic variations on the improvement of surgical outcomes under the CGM model.
Participants will receive CGM prescribed by the attending physician for at least 6 hours before surgery. Glucose monitoring should be continued until the 7th day after surgery or discharge.
The investigators will compare conventional monitoring group to see if CGM could reduce the CCIs for patients with diabetes or impaired glucose tolerance within 30 days after surgery.
Patients aged above 18 years;
Patients with diabetes mellitus or impaired glucose tolerance;
Expected major thoracic and abdominal surgery (except cardiac surgery; including endoscopic surgery and robotic surgery), open orthopedic surgery, neurosurgery;
Volunteered for this study and written informed consent.
The patient refused;
The time between wearing CGM sensor and surgical skin incision cannot meet 6 hours or more;
Expected monitoring time less than 72 hours in CGM group;
Patients had comorbidities that affected the evaluation of endpoints;
