Outcomes
Primary outcome [1] 266650 0
Organ Dysfunction will be measured using the sequential organ dysfunction assessment tool. This tool requires clinical and laboratory based data that is obtained routinely as part of standard care.
Timepoint [1] 266650 0
0, 6, 24 and 72 hours after trial enrolment
Secondary outcome [1] 276144 0
Sublingual microcirculation will be assessed using the microvision microscan sublingual microcirculation video microscope. Four measures of microcirculation will be calculated using this equipment; capillary density, microvascular flow index, percent of perfused capillaries and perfused capillary density.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients eligible for inclusion will be consented and enrolled while in the Emergency Department. This is an unblinded study. Random allocation concealment will be implemented through the use of serially numbered, tamper-evident envelopes. The envelopes contain group assignment, study instructions and data sheets
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation sequence will generated with the aid of random allocation software . Permuted block randomisation with variable block sizes will be used.
Masking / blinding
Open (masking not used)

Summary
Brief summary
Individuals who present to the Emergency Department with severe infections are treated with fluids in the vein to maintain optimal blood volume, keep the heart working properly, and keep tissues well oxygenated. There are a number of fluids that Emergency Physicians can provide to patients including saline and 4% albumin. Further work is required to determine which of these fluids is most effective in improving the outcome of patients with severe infection.

This project aims to determine whether 4% albumin solution is superior to crystalloid solutions for fluid resuscitation of patients presenting to the Emergency Department (ED) with septic shock. A randomised controlled trial is proposed, in which 100 patients will be enrolled over 2 years, each assigned to receive either 4% albumin or crystalloid fluids for the first six hours of resuscitation in the ED. All other aspects of care will be common to both groups and according to evidence-based guidelines. A variety of outcomes will be measured, including organ dysfunction scores, inflammatory markers and measures of circulation.
