Using furosemide to assess kidney recovery in critically ill patients on dialysis
Official title: Effect of a Furosemide Stress Test-Guided Strategy on Liberation From Continuous Renal Replacement Therapy in Critically Ill Patients With Acute Kidney Injury (FST-LIBERATE)
Run by Chiang Mai University · NCT06229990 · Data updated 2026-11-12
This study is testing if a special kidney stress test using furosemide can give better information about kidney recovery for critically ill adults on dialysis compared to standard care.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 20 and older with stage 3 acute kidney injury and oliguria who are receiving CRRT in an intensive care setting.
✕Probably not a fit
Patients with certain exclusions such as severe electrolyte imbalances, previous chronic kidney disease stage 5, or those on inotropic drugs may not benefit from this study.

What this trial studies
This clinical trial compares the effectiveness of a furosemide stress test (FST) against standard care in evaluating renal recovery in critically ill patients undergoing continuous renal replacement therapy (CRRT) for acute kidney injury. The study aims to determine if the FST can provide better insights into kidney function recovery compared to traditional methods. Participants will be adults with stage 3 acute kidney injury who have been on CRRT for at least 48 hours. The trial seeks to address the lack of evidence regarding the timing of withholding CRRT and its associated complications.
Why it matters
Potential benefit: If successful, this approach could lead to improved assessment of kidney recovery and potentially reduce complications associated with prolonged CRRT.
How similar studies have gone: While the use of furosemide stress tests has been explored in other contexts, this specific application in critically ill patients undergoing CRRT is relatively novel.
