ICU kidney trial aims to find best fluid removal rate
NCT ID NCT05817539
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two approaches to removing excess fluid in intensive care patients with acute kidney injury who are on dialysis. One group will have fluid removed at a moderate rate to actively reduce fluid buildup, while the other group will have fluid removed slowly to just maintain current levels. The goal is to see which strategy leads to fewer days on life support and better recovery. The trial plans to enroll 250 adults in the ICU.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrafiltration (fluid removal) procedure
- What this could lead to
- If successful, this could establish a safer, more effective way to remove excess fluid in ICU patients on dialysis, potentially reducing time on life support and improving survival.
- What could go wrong
- This is a moderate-sized early-stage trial, so results may not apply to all ICU patients. Aggressive fluid removal can cause low blood pressure or organ injury, and the benefit over standard care is unproven.
