Tight glycaemic control (TGC)
Conventional glycaemic control (Control)
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.
Conventional glycaemic control aims to control blood sugar less than 250 mg%. Insulin was given bolusly if the blood sugar more than 250 mg%.
