#4-82E. Rethinking Resuscitation: Vasopressors vs. Fluids in Early Septic Shock (NEJM, 2026)

What is the optimal initial fluid strategy for patients presenting to the emergency department with septic shock? The ARISE FLUIDS trial addresses this crucial question by comparing a restricted fluid strategy with early vasopressor initiation against a more liberal fluid approach with delayed vasopressors. The study found no significant difference between the two groups regarding the number of days alive and out of the hospital at day 90. However, the most critical clinical takeaway is that while the restricted fluid approach did not improve overall survival, it significantly reduced the risk of pulmonary edema from 5.0% to 0.6%. When critically appraising this paper, it is important to consider that it was an open-label trial and that clinical management beyond the initial 24-hour intervention period was not controlled, which might have influenced downstream outcomes. For our physician listeners, this study is highly relevant because it challenges current guideline recommendations for uniform, large-volume fluid resuscitation, suggesting instead that a fluid-restrictive approach utilizing early vasopressors could successfully mitigate the risk of fluid overload and pulmonary edema in daily critical care practice.
