OBJECTIVE: In a fulminant porcine sepsis model, we determined the kinetics of hypoxia induced changes in relation to sepsis parameters and markers of organ damage. METHODS: Female pigs were challenged by live Escherichia coli and samples were analysed up to 4 hours. Bone marrow reactions were determined by analysing immature forms of peripheral blood cells by a hematology analyser and light microscopy. Platelet mitochondrial membrane depolarisation was determined by flow cytometry. RESULTS: Core temperature, modified shock index and lactate levels all became significantly elevated compared to baseline values at 4 hours in septic animals. At 2 hours already the reticulocyte count, nucleated red blood cell count and the absolute number of dysplastic platelets became significantly elevated. The platelet mitochondrial membrane depolarisation was significantly decreased by 2 hours in septic animals compared to the baseline values and to control animals. No massive organ damage was evident during the 4-hour observation period, but uric acid levels in septic animals became significantly elevated already by 2 hours. CONCLUSIONS: In this Escherichia coli induced porcine model, severe sepsis was evident by conventional criteria at 4 hours while several - mostly hypoxemia induced - biomarkers were already altered by 2 hours.
