Effectiveness of Continuous Glucose Monitoring System Among Cardiac Surgery Patients

Effectiveness of Continuous Glucose Monitoring System Among Cardiac Surgery Patients

The aim of this study is to assess the level of glycemic control and the incidence of surgery-related complications in cardiac patients post-surgery when Continuous Glucose Monitoring (CGM) is utilized, as compared to traditional methods of arterial/venous blood sampling and Point-of-Care Testing (POCT) for glucose monitoring.

Inclusion Criteria:

• Subjects waiting for Elective Cardiac Surgery (CABG, Cardiac Valve Operation, Congenital heart anomaly surgery, aortic surgery, etc.)

• Subjects over the age of 18

• Patients with type 2 diabetes

• Patients with prediabetes

  1. HbA1c 5.7% or more
  2. fasting blood glucose 100 mg/dL or more
  3. 2 hours 75g-OGTT 140 mg/dL or more

Exclusion Criteria:

• Emergency surgery patients

• Patients performing co-operation other than cardiac surgery

• Patients with type 1 diabetes

• Total Pancreatectomy patients

• Patients with high surgical severity (STS score of 8 or more or EURO score of 5 or more)

• Patients who do not consent to the study

• Severe patients who are deemed difficult to continue research during surgery (excluded at the researcher's discretion)

  1. Cases where severe weight gain and severe edema occur after surgery
  2. Cases where the surgery time is significantly longer than average
  3. Cases where cardiopulmonary bypass is used more than once during surgery

• Others who are deemed unsuitable for research progression at the researcher's discretion
