Intravenous Exenatide (Byetta) During Surgery

"Exenatide to be infused intravenously at 0.27 ng/kg/min (0.066 pmol/kg/min) for a duration of 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)."

"Intravenous Placebo of NSS infused at same rate as drug comparator. Induction of anesthesia will be equal to Intubation time.
