COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Healthy volunteers will receive a peripheral venous catheter and an arterial catheter. They will then receive a bolus of 13-labelled lactate (2.7mg/kg) and blood samples will be drawn continuously during the next two hours (not more than 100ml blood will be drawn).

Outcomes
Primary outcome [1] 300949 0
Enrichment of 13-lactate. Rate of appearance and rate of disappearance of endogenous lactate will be assessed by Gas Chromatography-Mass spectrometry (GC-MS)
Timepoint [1] 300949 0
Samples are taken at baseline and throughout the following two hours, every other minute the first hour and every fifth minute the second hour (t=0 and at time points: 2, 4, 6,... 56, 58, 60, 65, 70, 75... 110, 115, 120)
Secondary outcome [1] 331258 0
Normalization of lactate levels after bolus, defined as return to baseline levels (t=0).
Timepoint [1] 331258 0
Samples are taken at baseline and throughout the following two hours, every other minute the first hour and every fifth minute the second hour (t=0 and at time points: 2, 4, 6,... 56, 58, 60, 65, 70, 75... 110, 115, 120)

Summary
Brief summary
In order to study lactate kinetics in ICU patients with a minimally invasive technique we are performing this pilot study on healthy volunteers.
After a standard health form, medical examination and testing the fasting subjects will receive venous and arterial catheters. Base line samples are drawn and frozen. A bolus of stable isotopically labeled 13C-lactate will be given (2.7mg/kg body weight). Blood samples will be drawn at 37 time points throughout 2 hours (not more than 100ml blood al together). Samples will be analyzed at bedside analyzer and snap frozen for later analysis for relationship between 13C-labelled and normal lactate.
Subjects will monitored with ECG, pulsoximetry and blood pressure throughout the experiment.
