Primary Outcome Measures
NameTimeMethod
Circulating levels of interleukin-1 (used as an indicative inflammatory cytokine) compared to baseline level before fluid bolus. 3.5 mL serum tubes are collected from the patients at the requisite timepoints, allowed to stand at room temperature for 30 minutes to clot then centrifuged at 800g for 10 minutes at 4 deg C. Serum and plasma samples are aliquotted, stored immediately at -80 deg C and subsequently analysed using ELISA.[1, 3 and 24 hours after fluid bolus]
Secondary Outcome Measures
NameTimeMethod
Inflammatory gene activation and expression measured using qPCR compared to baseline level before fluid bolus. At the requisite timepoints 2.5mL PAXGene tubes are collected. The PAXgene tube is placed immediately at 4 deg C before being transferred to -20 deg C with 72 hours, and then transferred to -80 deg C for long-term storage and subsequent qPCR analysis.[1, 3 and 24 hours after fluid bolus];Bacterial load compared to baseline level before fluid bolus. Bacterial load is measured from PAXGene tubes as above.[1, 3 and 24 hours after fluid bolus];Haemodynamic parameters (e.g. mean arterial pressure, systolic pressure, heart rate measured non-invasively using standard equipment) compared to baseline level before fluid bolus[1, 3 and 24 hours after fluid bolus];Mortality measured by review of medical records and, where necessary, telephone follow up[28 days from enrolment]
