Primary Outcome Measures:
  • nosocomial infection [ Time Frame: within the first 30 day after surgery ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • morbidities and all causes mortality [ Time Frame: within the first 30 days after surgery ] [ Designated as safety issue: Yes ]
    morbidities defined as hypoglycaemia (blood sugar less than 60 mg%), Stroke (focal neurological deficit confirmed with CT or MRI), acute renal failure (rising of creatinine)

Arms Assigned Interventions
Experimental: Tight glycaemic control (TGC) Drug: TGC blood sugar 80-150 mg%
TGC used hyperinsulinaemic normoglycaemic clamp with modified glucose-insulin-potassium to control blood sugar. The insulin (HumulinTM R, Lilly pharma, Germany) was diluted with normal saline to the concentration 1 IU. mL-1 and was infused continuously throughout the operations at a fixed rate of 0.3 IU. kg-1.h-1 but the maximal rate was 20 IU/ h. A separate mixture of glucose 25% (A.N.B Laboratories, Thailand) 50 mL, potassium chloride (Nida pharma, Thailand) 20 mEq and magnesium sulfate (Atlantic, Thailand) 2 gm was infused at 0.75 mL.kg-1.h-1 and was adjusted to maintain blood glucose levels 80-150 mg/dL.
Other Name: intensive glycaemic control
No Intervention: Conventional glycaemic control Drug: Conventional glycaemic control
Conventional glycaemic control aims to control blood sugar less than 250 mg%. Insulin was given bolusly if the blood sugar more than 250 mg%.
Other Name: Control group

Detailed Description:
Hyperglycaemia develops frequently in patients undergoing cardiac surgery, especially following cardiopulmonary bypass (CPB). Recent evidence suggests that acute hyperglycaemia adversely affects immune function, wound healing and cardiovascular function.
