Despite improvements in surgical techniques and perioperative care, the high incidence of postoperative surgical site infections remains a major problem in patients undergoing major abdominal surgery (liver, pancreatic and colorectal surgery).

Using the hyperinsulinemic-normoglycemic clamp technique, i.e. continuous infusion of insulin combined with dextrose titrated to "clamp" blood glucose between 4 and 6 mmol/L, we successfully established and preserved normoglycemia during the perioperative period. Our objective of this study is to determine if the maintenance of perioperative normoglycemia by a hyperinsulinemic normoglycemic clamp reduces the rates of incisional and space/ surgical site infections following abdominal surgery (liver, pancreatic and colorectal surgery).

Primary Outcome Measures:
  • Surgical site infection [ Time Frame: for 30 days after surgery ] [ Designated as safety issue: No ]
    Surgical site infections will be defined according to the CDC's NNIS system.

Secondary Outcome Measures:
  • Surgical morbidity [ Time Frame: 30 days after surgery ] [ Designated as safety issue: No ]
    Surgical morbidity in the 30 days following the operation will be assesse as per Clavien score.

Estimated Enrollment: 540
Study Start Date: February 2012
Estimated Primary Completion Date: January 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Standard glucose management Other: Standard glucose management
Blood glucose levels will be treated by a standard insulin sliding scale.
Active Comparator: Hyperinsulinemic normoglycemic clamp Other: Hyperinsulinemic normoglycemic clamp
Patients will receive an IV infusion of 2 mU/kg/min (0.12 U/kg/hour) starting in the operating room. Dextrose 20% will be titrated to maintain blood glucose between 4 and 6 mmol/l. At the end of surgery, the insulin infusion will be stopped and the dextrose infusion weaned off in the postanesthesia care unit.
