Outcomes
Primary outcome [1] 279680 0
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.
Timepoint [1] 279680 0
1, 3 and 24 hours after fluid bolus
Secondary outcome [1] 294186 0
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.
Timepoint [1] 294186 0
1, 3 and 24 hours after fluid bolus
Secondary outcome [2] 294187 0
Bacterial load compared to baseline level before fluid bolus. Bacterial load is measured from PAXGene tubes as above.
Timepoint [2] 294187 0
1, 3 and 24 hours after fluid bolus
Secondary outcome [3] 294188 0
Haemodynamic parameters (e.g. mean arterial pressure, systolic pressure, heart rate measured non-invasively using standard equipment) compared to baseline level before fluid bolus
Timepoint [3] 294188 0
1, 3 and 24 hours after fluid bolus
Secondary outcome [4] 294189 0
Mortality measured by review of medical records and, where necessary, telephone follow up
Timepoint [4] 294189 0
28 days from enrolment

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will be identified by clinical staff working in the emergency department and , once informed consent is obtained, allocation will occur by logging on to a secure website that will randomise the patient to their treatment group. The staff identifying inclusion criteria is therefore unaware to which arm the patient will be randomised until after they consent the patient and log on to the website.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be randomised in real time utilising a web based randomisation system
Masking / blinding

Summary
Brief summary
Patients with sepsis have the potential to become very unwell in a rapid period. The progression from being moderately unwell to severely unwell may be due to the body’s immune system responding to the infection, rather than the infection itself.
A fundamental and accepted practice in the management of patients with suspected sepsis is the administration of intravenous fluids. There is no consensus that any particular fluid is better than the other. In particular, we do not know whether any time of fluid has a beneficial effect on this immune response to infection.
Hypertonic saline fluid has been shown in some animal and human studies to influence the immune response to infection. In this pilot study we will assess whether hypertonic saline has an advantage over normal saline in producing beneficial immunomodulation. If this can be shown, it will inform the design of a larger multicentre trial with clinical endpoints.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
Trial was envisaged, designed and approved before these requirements became commonplace.The PICF for this trial clearly states that only the investigators will have access to participant data, and it is unethical to now share these data
