ER shock showdown: less fluid, early pressors vs. standard care
NCT ID NCT04569942
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two strategies for treating septic shock in the emergency department. One group gets less IV fluid and starts blood-pressure-raising drugs (vasopressors) early. The other group gets more IV fluid first, then vasopressors if needed. The trial includes 1000 patients across Australia and New Zealand and tracks how many days they are alive and out of the hospital up to 90 days later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vasopressors (e.g., noradrenaline) and IV fluids
- What this could lead to
- If it works, this could show that using vasopressors early with less fluid is a better way to treat septic shock, potentially improving survival and recovery.
- What could go wrong
- This is a large phase 3 trial, but results may not apply to all sepsis patients. The best approach may depend on individual patient factors, and there are risks from both too little fluid and from vasopressors.

Inclusion Criteria: * Clinically suspected infection; * Systolic blood pressure (SBP) \<90 mm Hg or mean arterial pressure (MAP) \<65 mm Hg, despite a ⩾1000ml cumulative total bolus of IV fluid administered over a maximum of 60 minutes; including pre-hospital boluses; * Arterial or venous blood lactate \>2.0 mmol/L; * At least one dose of an intravenous antimicrobial has been commenced. Exclusion Criteria: * Age \<18 years; * Confirmed or suspected pregnancy; * Transferred from another acute care facility; * Hypotension suspected to be due to a non-sepsis cause; * \>2L total IV fluid administered (including prehospital fluids but excluding drugs and flushes); * More than 6 hours has elapsed since presentation to the ED or more than 2 hours has elapsed since last inclusion criterion has been met; * Treating clinician considers that one or both of the treatment regimens are not suitable for the patient or the study protocol cannot be delivered e.g. limitation of care, requirement for immediate surgery; * Death is considered imminent or inevitable; * Underlying disease that makes survival to 90 days unlikely; * Inability to follow patient up to day-90 e.g. unstable accommodation, overseas visitor; * Previously enrolled in this study.
