Continuous insulin infusion improves postoperative glucose control in patients with diabetes mellitus undergoing coronary artery bypass surgery.

Abstract: Postoperative glucose control directly affects the incidence of deep sternal wound infection and death after patients with diabetes have undergone coronary artery bypass grafting. We compared the effect upon glucose control of continuous insulin infusion with that of glucometer-guided insulin injection after coronary artery bypass. Our prospective, randomized, controlled study involved patients with diabetes mellitus who underwent coronary artery bypass grafting in our hospital from January 2001 through January 2003. Immediately after surgery, patients were randomly assigned to receive continuous insulin infusion or conventional glucometer-guided injection to maintain blood glucose at a level between 150 and 200 mg/dL. The adequacy of postoperative blood glucose control and clinical outcome were evaluated. Of 93 patients studied, the incidence of sternal wound infection was 3.9% among infusion patients and 4.8% among injection patients (P=0.587). There was no significant difference in mortality rates (infusion, 3.9%; injection, 2.4%; P=0.573). Satisfactory blood glucose levels were achieved in significantly more patients undergoing infusion than injection (64.7% vs 28.6%, P <0.001). In the injection group, significantly more blood glucose measurements were required to achieve control (23.4 vs 16.5, P=0.001), and good control was attained much sooner in the infusion group (21.4 vs 30.5 hr, P=0.013). We conclude that continuous insulin infusion provides better control of postoperative blood glucose levels after coronary artery bypass grafting in patients with diabetes than does glucometer-guided insulin injection.
