简要总结
This research study is designed to better understand post-operative complications as related to the tightness of blood sugar control. It is also hoped that we may learn that a more liberal control of your blood sugars is not inferior to the current strict glucose control. Our ultimate goal is to evaluate if there is any change in the rates of complications between the two groups. We will be comparing the current strict blood glucose control with a more liberal target for blood sugars.
详细描述
Hyperglycemia is commonly encountered following cardiac surgery, whether a patient has a history of diabetes or not. Hyperglycemia has been associated with increased perioperative morbidity and mortality; several studies have demonstrated that glycemic control utilizing insulin protocols improves operative mortality, lowers operative morbidity (mediastinitis, atrial fibrillation), and improves long-term survival. However, the optimal target for serum glucose has not been established in post-CABG patients.
Methods:
All CABG patients will be consented prior to surgery. Inclusion criteria for non-diabetic patient is a random fingerstick blood glucose (FSBG) above >150 mg/dL prior, during, or immediately following surgery. All patients with history of diabetes mellitus (Type 1 or Type II) will be immediately eligible for inclusion.
Following CABG surgery, if the patient was started intra-operatively on an insulin infusion, then that patient will be randomized to one of two treatment target groups: Group 1 [Blood Glucose (BG): 80 mg/dL-120 mg/dL] or Group 2 [BG: 121-180 mg/dL]. The randomization design will be a 1:1 allocation of patients between the two groups, with both diabetic and non-diabetic patients enrolled in both arms of the study. Patients will be maintained on an electronic-based protocol of intravenous insulin for a minimum of 72 hrs postoperatively. Patients remaining in the CVICU greater than 72 hrs will have their intravenous insulin continued until transfer to the step-down unit.
The Glucommander© will be programmed to adjust the insulin drip to one of these two target groups. The nursing staff will not be blinded to treatment group allocation. The primary endpoint with be a composite of operative death, major adverse cardiac events (MACE: death, myocardial infarction, re-vascularization), STS Defined Major Morbidity (re-operation, Cerebrovascular accident, Deep Sternal Wound Infection/Mediastinitis, Prolonged Ventilatory Support (> 24 hrs), Acute Renal Failure), and prolonged inotropic support. The pre-specified sub-group analysis will compare perioperative outcome of patients with diabetes vs non-diabetic patients.
