Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Glucagon-like peptide-1 at 1.2pmol.kg.min infused at 1ml/min between t=0-270min. Participants will cross-over to the other arm (i.e. GLP-1 to control and vice-versa) on the next consecutive day (as GLP-1 is rapidly metabolised with a t1/2 < 5mins)
Intervention code [1] 3994 0
Treatment: Other
Comparator / control treatment
Cross-over study
Cross-over treatment is 4% albumin infusion (which has no effect on blood glucose) infused at 1ml/min between t=0-270minutes
Control group
Active

Study design
Purpose of the study
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. Synthetic GLP-1-(7-36) amide is reconstituted by the Royal Adelaide Hospital department of pharmacy, as a solution in 4% albumin. Randomisation is performed by the department of pharmacy, so that on each study day the investigators receive the study drug in a glass bottle covered by black plastic.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer sequence generation
Masking / blinding
Blinded (masking used)
