ARISE FLUIDS trial finds restrictive fluids with early vasopressors yields equivalent 90-day survival while reducing pulmonary edema in septic shock

Brief summary
In the ARISE FLUIDS randomized trial of 1,000 emergency department patients with septic shock, early vasopressor initiation combined with restrictive fluid volumes showed no difference in 90-day survival compared with liberal fluids, but significantly lowered pulmonary edema rates.
What NurseJet pulled from the source
Clinical equipoise has persisted regarding whether early septic shock resuscitation should emphasize large intravenous fluid boluses or prompt vasopressor administration with fluid restriction. The multicenter ARISE FLUIDS trial randomized 1,000 adult emergency department patients presenting with septic shock to either a restrictive fluid protocol with early vasopressors or a higher-volume fluid protocol with later vasopressors for up to 24 hours (analyzing 963 patients in the intention-to-treat population). Patients in the restrictive vasopressor group received a median of 1,108 mL less intravenous fluid over the first 24 hours (median difference -1,108 mL; 95% CI -1,395 to -850 mL) and had an 18.9 percentage point higher rate of vasopressor exposure. At day 90, the median days alive and out of the hospital was identical between groups (76 days vs 76 days; difference 0.0 days; 95% CI -2.7 to 2.7; P = 1.00). However, the restrictive fluid strategy significantly lowered the incidence of new-onset pulmonary edema compared with the liberal fluid arm (0.6% vs 5.0%; P < 0.001).
Why this matters for nurses
Emergency and critical care nurses frequently administer rapid fluid boluses during early sepsis alerts, sometimes facing fluid overload, worsening gas exchange, and acute respiratory decompensation. This trial demonstrates that initiating vasopressors early while restricting total fluid intake provides equivalent 90-day survival while avoiding excess fluid overload and reducing pulmonary edema nearly eightfold.
Bedside takeaway
In 1,000 ED patients with septic shock, early vasopressors with fluid restriction matched 90-day survival (76 vs 76 days alive and out of hospital) while reducing pulmonary edema (0.6% vs 5.0%).
Key takeaways
- Multicenter randomized trial evaluated 1,000 adult emergency department patients with septic shock assigned to fluid restriction plus early vasopressors versus higher-volume fluid resuscitation.
- Median days alive and out of the hospital at day 90 was identical across groups (76 days in both arms; P = 1.00).
- The restrictive protocol delivered a median of 1,108 mL less intravenous fluid during the initial 24 hours of resuscitation.
- Pulmonary edema occurred in significantly fewer patients in the restrictive vasopressor group compared to the higher-volume fluids group (0.6% vs 5.0%; P < 0.001).
Practice implications
- Closely monitor fluid responsiveness rather than relying on routine reflex large-volume crystalloid boluses in septic shock. Coordinate early central or peripheral vasopressor infusion per unit protocol when mean arterial pressure remains refractory, and auscultate lung fields frequently to assess for early signs of pulmonary congestion.
Limitations & cautions
- Conducted in emergency departments in Australia and New Zealand where baseline resuscitation practices and early critical care access may vary from other international healthcare systems; unblinded clinical intervention.
