Australasian Resuscitation In Sepsis Evaluation: FLUid or Vasopressors In Emergency Department Sepsis

The ARISE FLUIDS study is a multicentre, randomised, parallel group clinical trial of a restricted fluids and early vasopressor strategy compared to a larger initial IV fluid volume and later vasopressors for the haemodynamic resuscitation of patients with septic shock presenting to the ED. It will be conducted in hospitals in Australia and New Zealand with 1000 patients recruited over a 3-year period. Each patient meeting all of the inclusion and none of the exclusion criteria will be randomised to receive haemodynamic resuscitation using either a restricted fluid and early vasopressor regimen (vasopressors arm) or a larger initial fluid resuscitation volume (fluids arm) followed by later introduction of vasopressors (if required). The intervention will be commenced in the ED and delivered for at least 6 hours, and up to 24 hours post-randomisation if admitted to the ICU or other critical care area where the study protocol can be faithfully delivered. Treatment will revert to usual care as determined by the treating clinician when the patient is transferred to a non-critical care ward. All enrolled participants will be followed up and assessed for the defined study outcomes. Participants will be identified using a systematic approach to screening and assessment of patients with possible sepsis presenting to the ED in accordance with standard clinical practice.
