entGlycemic control has been found to improve clinical outcomes following Coronary Bypass Surgery. This study tests the hypothesis that obtaining tighter glycemic control(80-120mg/dl) as opposed to more moderate control (120-180mg/dl) will further improve outcomes.

Arms Assigned Interventions
Active Comparator: 1Moderate Glycemic Control
Patients will receive an insulin drip to keep blood glucose levels between 120-180mg/dl
Drug: IV Insulin drip
IV insulin drip at 100units insulin in 100ml saline designed to keep blood glucose between 120-180mg/dl
Active Comparator: 2Aggressive Glycemic Control
Patients will receive an insulin drip designed to maintain serum glucose between 80-120mg/dl
Drug: Insulin
IV insulin drip to keep serum glucose between 80-120mg/dl.

Detailed Description:

150 diabetic patients will be randomized to achieve aggressive glycemic control (80-120mg/dl) vs moderate control (120-180mg/dl) using intravenous insulin infusions beginning at anesthetic induction and continuing for 18 hours following surgery.
