Description of intervention(s) / exposure
A 60ml Intraduodenal infusion at 120ml/hr of liquid nutrient mixed with 13C-triolein and 3-OMG infused into healthy volunteers

Treatment: Other
Comparator / control treatment
The control group consists of healthy volunteers. This group is age and sex matched with critically ill patients who have previously been studied by the investigators using the same method between 2010 and 2011.

Historical

Outcomes
Primary outcome [1] 287995 0
The primary outcome will be lipid absorption in the healthy population, which can then be compared to the data that the investigators have already obtained in the critically ill, mechanically ventilated population.
Lipid absorption is derived from end-expiratory breath samples (10mL) for the measurement of the 13C-Triolein by-product, 13CO2, which will be taken throughout the study.
Timepoint [1] 287995 0
At baseline, 5, 15, 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 and 360 minutes after the commencement of the infusion.
Secondary outcome [1] 299225 0
Glucose absorption as derived from the area under the 3-OMG concentration curve, peak concentration and time to peak. This will be measured from venous blood samples(5ml).
Timepoint [1] 299225 0
At baseline, 5, 15, 30, 45, 60, 90, 120, 150, 180, 240, 300 and 360 minutes after the commencement of the infusion.
Secondary outcome [2] 299226 0
Plasma concentration of motilin measured from venous blood samples (4ml).
Timepoint [2] 299226 0
At baseline, 30 and 240 minutes after the commencement of the infusion.

Summary
Brief summary
The purpose of this study is to understand how healthy people absorb glucose (sugar) and lipids (fat) from their small intestine. This information can then be compared to information we are collecting about nutrient absorption in Intensive Care Unit patients. We hypothesize that absorption will be reduced in Intensive Care Unit patients compared to healthy volunteers.
