Brief Summary:
This study seeks to determine whether varying the dose of insulin and glucose in diabetic patients during coronary bypass surgery will improve outcomes in these patients.

Condition or disease Intervention/treatment Phase
Glycemic Control Drug: A IV Insulin drip Drug: B Low Dose GIK Drug: C High Dose GIK Phase 1

Detailed Description:
Our previous study has shown that maintaining serum glucose between 120-180mg/dl in the perioperative period during CABG surgery in diabetic patients improves outcomes. The purpose of this trial is: (1) to determine whether outcomes can be improved by altering the content of glucose or insulin in these solutions (2)to determine the effect of these solutions and glycemic control on the inflammatory response of arterial and venous conduits used during surgery, (3) to determine whether the beneficial effects of improved glycemic control can be correlated with changes in the inflammatory response.

Arm Intervention/treatment
Active Comparator: B Low dose GIK
This group will have low doses of glucose and insulin
Drug: B Low Dose GIK
These patients will receive D5W+80unitsInsulin+40mEqKCL IV to keep blood glucose between 120-180mg/dl

Active Comparator: C High Dose GIK
This group will have high doses of insulin and glucose
Drug: C High Dose GIK
This group will receive D20W+160units IV insulin to keep blood sugar between 120-180mg/dl

Active Comparator: A Insulin
This group will receive only an intravenous insulin infusion
Drug: A IV Insulin drip
These patients will receive 100units of insulin in 100ml of saline intravenously to keep blood glucose between 120-180mg/dl.

Primary Outcome Measures :
  1. glycemic control, postoperative morbidity, inflammatory markers [ Time Frame: 24 hours following surgery ]
  2. glycemic control [ Time Frame: 24 hours following surgery ]

Secondary Outcome Measures :
  1. free fatty acid levels [ Time Frame: 24 hours following surgery ]
