About this study
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)
Currently, continuous renal replacement therapy (CRRT) is the main modality for renal support in critically ill patients with hemodynamic instability. Most studies have investigated the timing of RRT initiation. However, prolonged CRRT demonstrated the association of many unexpected events, such as catheter-related complications, catheter-related blood stream infection, hypotension, hypothermia, tachycardia, and atrial fibrillation. Up to now, there is a lack of evidence regarding the timing of withholding CRRT. The furosemide stress test (FST) is a tool that is easy to use and has more availability. The investigators aimed to apply FST to evaluate renal recovery compared with standard treatment in critically ill patients undergoing CRRT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Furosemide InjectionDrug
Also called Furosemide stress test
After taking furosemide at 1.5 mg/kg intravenously, if the urine output exceeds 200 mL within 2 hours, the patients are going to withhold CRRT. But if there is no response, the titration of furosemide to 2.5 mg/kg and 3.5 mg/kg every 6 hours is scheduled according to the urine output >200 mL in 2 hours (not exceeding 250 mg).
| Study group | Role | What they receive |
|---|---|---|
| Protocol based-furosemide stress test | Experimental | Furosemide at 1.5 mg/kg intravenously Receives: Drug: Furosemide Injection |
| Standard care | No intervention | Standard CRRT care without furosemide use during treatment. |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Furosemide Injection in people with Acute Kidney Injury, run by Chiang Mai University at 1 site in Thailand.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Prit Kusirisin, MD (+66897574028, jingprit@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Successful liberation from CRRT (time frame: 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06229990, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2026.
