  Purpose

Epidural anesthesia has been found to manipulate the hyperglycemic response to surgery. It is unclear, however, whether the preoperative metabolic status of the surgical patient plays a role in the degree of this hyperglycemic response. For instance, the presence of low insulin sensitivity before surgery could predispose the individual to an altered metabolic response after surgery. In this case, it would be appropriate to identify adequate interventions that attenuate the response to surgical stress and facilitate the recovery process.

The aims of this research projects are the following:

  1. To determine the extent in which epidural local anesthetics, initiated before surgery and continued after surgery, improves insulin secretion in patients with preoperative low insulin sensitivity.
  2. To understand which measures of postoperative recovery are sensitive to the restoration of insulin secretion in this particular group of patients

Primary Outcome Measures:
  • Hyperinsulinemic-euglycemic clamp [ Time Frame: up to 2 days after surgery ]
    The Hyperinsulinemic-euglycemic clamp is the gold standard for measuring insulin sensitivity. Patients receive a 2 hour infusion of glucose and insulin, which is adjusted throughout the study period in order to maintain a blood glucose concentration at 5.5mmol/L. The test will take place one week before surgery and on the second postoperative day.


Enrollment: 30
Study Start Date: November 2012
Study Completion Date: November 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: General Anesthesia
Patients will receive general anesthesia alone followed by intravenous morphine for postoperative pain control. This techniques is safe and is standard procedure for colorectal surgery.
Procedure: Anesthesia
Patients will be randomized to receive either epidural or general anesthesia for pain management throughout their surgery.
Experimental: Epidural Anesthesia
Patients will receive general anesthesia plus epidural anesthesia followed by epidural analgesia for postoperative pain control. This techniques is safe and standard procedure for colorectal surgery.
Procedure: Anesthesia
Patients will be randomized to receive either epidural or general anesthesia for pain management throughout their surgery.
