Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This randomized, open-label, controlled trial will be performed in adult (\>18 years old) patients scheduled for elective open abdominal aortic aneurysm repairs and open hepatobiliary procedures including liver resections, pancreatectomies, duodenectomies, gastrojejunostomies, choledochojejunostomies and hepaticojejunostomies) at the Royal Victoria Hospital (RVH), McGill University Health Centre (MUHC), Montreal, QC, Canada.

Inclusion criteria: above 18 years old, scheduled for elective open abdominal aortic aneurysm repairs and open hepatobiliary procedures.

Exclusion criteria: inability to give consent, current wound infection, previous surgery at the same site within the preceding 30 days, allergy to insulin.

RECRUITMENT

Initial contact prior to surgery will be made by a research team member not involved in the care of the patient who will explain the research project and obtain written consent.

Consenting patients will then be randomized with the assistance of a computerized randomization system.

Standard glucose management

Arterial-blood glucose levels will be checked at induction of anesthesia and every 30 - 60 min thereafter with an StatStrip Xpress® (Nova Biomedical, MA, USA) ( A blood glucose level above 10 mmol/l will be treated with a 2U bolus of IV insulin (Humulin® R regular insulin, Eli Lilly and Company, Indianapolis, IN) followed by a 1 U/hour drip infusion adjusted according to a standard sliding scale

Group Type PLACEBO_COMPARATOR

Standard glucose management

Intervention Type OTHER

Blood glucose levels will be treated by a standard insulin sliding scale.

Hyperinsulinemic normoglycemic clamp

The blood glucose level will be checked prior to intubation. A 2U bolus of IV insulin will be given if blood glucose level is higher than 6 mmol/l, followed by an IV infusion of 2 U/kg/min (0.12 U/kg/hour). Dextrose 20% (D20W®) will be titrated to maintain blood glucose between 4 and 6 mmol/l. Blood glucose levels will be measured at 5-30 min intervals with a to ensure normoglycemia. At the end of surgery, the insulin infusion will be stopped, and the dextrose infusion weaned off in the post anesthesia care unit.

Group Type ACTIVE_COMPARATOR

Hyperinsulinemic normoglycemic clamp

Intervention Type OTHER

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.
