Experimental
Placebo Comparator
Exentatide 0.27 ng/kg/min
Exentatide 0.41 ng/kg/min
Placebo IV NSS
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).
