Outcomes
Primary outcome [1] 269188 0
To determine whether the addition of exogenous glucose-dependent insulinotropic polypeptide (GIP) to glucagon-like peptide-1 (GLP-1) has a glucose-lowering effect in critically ill patients (as measured by area under the curve)
Timepoint [1] 269188 0
Blood glucose will be measured at 15min intervals between t=0-270min
Secondary outcome [1] 279091 0
To establish if exogenous GIP, with concurrent GLP-1 has an additive insulinotropic effect in the critically ill.
Timepoint [1] 279091 0
Plasma Insulin measured at t=0, 30, 60, 90, 120, 150, 210 and 270 min

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients admitted to the Intensive Care Unit (ICU) of the Royal Adelaide Hospital will be screened. Next of kin will be approached for informed consent.
Study drug ,synthetic GIP and GLP-1 and placebo 0.9% saline and synthetic GLP-1 will be reconstituted by the Royal Adelaide Hospital Department of Pharmacy, as a solution in 4% albumin. Randomisation will be performed by the Department of Pharmacy, so that on each study day the investigators receive the study drug in a glass bottle coved by black plastic, therefore allocation concealment is maintained.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer sequence generation by the department of pharmacy.
Masking / blinding
Blinded (masking used)
