Arm Description

Exenatide to be infused by intravenous method at 0.27 ng/kg/min (0.066 pmol/kg/min) over 3-6 hours. Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin, Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).

Experimental: IV Exenatide to be infused by intravenous method at 0.41 ng/kg/min (0.099 pmol/kg/min) over 3 to 6 hours. Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin,Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).

Placebo of IV normal saline solution as comparator. Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin, Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).

Outcomes

Primary Outcome Measures

The Primary Objective is to Determine the Ability of Intravenous Exenatide to: Maintain Intraoperative Euglycemia in Subjects With Initial Blood Glucose < 126 mg/dL in Surgical Subjects as Compared to Placebo,
Logistic regression analysis will be utizlized to determine maintenance of euglycemia (yes v no) for our primary analysis. A standard area under the curve (AUC) analysis will be performed for each time point to map out drug deposition. Assuming a standard 2 compartment model, 10 subjects per group is sufficient to accurately predict mean AUC. Our primary analysis should provide ample statistical power.

5. Study Description

Brief Summary
The purpose of this project is to study if intravenous Exenatide is effective at maintaining normal blood glucose levels and preventing low blood glucose levels during surgery.
Detailed Description
This is a single-center, block randomized, double-blind, placebo-controlled, dose-ranging study. Subjects will be randomized in equal proportions to one of three treatment arms: placebo of normal saline solution, 0.27 ng/kg/min (0.066 pmol/kg/min) IV Exenatide, and 0.41 ng/kg/min (0.099 pmol/kg/min) IV Exenatide. We will use a block number of 30 (please see power analysis) so that balance between each of the three groups will be maintained over the enrollment period. We will stratify the randomization scheme to ensure balance of diabetics and non-diabetics within the groups.
