A simple glucose insulin regimen for perioperative blood glucose control: the Vellore regimen.

In this study, we sought a simple, easily implemented method of intraoperative control of blood glucose in diabetic patients in a large multispecialty teaching hospital. The Vellore regimen, which offers the advantages of a combined glucose insulin and variable rate infusion was evaluated. For every 1 to 50-mg/dL increase in blood glucose concentration more than 100 mg/dL, 1 U of insulin was added to the injection port of a 100-mL measured volume set containing 5% dextrose in water. Hourly monitoring of blood glucose was performed. The blood glucose control was compared with the different existing techniques followed in the hospital in 204 randomized patients: 98 in the study and 106 in the control group. The study group had a mean +/- sd blood glucose value of 156 +/- 36 mg/dL, and the control group's value was 189 +/- 63 mg/dL (P = 0.003). The percentage of patients who were poorly controlled (outside 100 to 200-mg/dL range) decreased from 51% to 28% (no patient less than 60 mg/dL) with this regimen as compared with the control group in which it increased from 49% to 72% (10 patients less than 60 mg/dL) (P = 0.0013). We conclude that the Vellore regimen is simple, effective, and safe for intraoperative blood glucose control.
