Nephroprotection for severe trauma patients with early urine signs of kidney stress

Impact of a Nephroprotection Bundle-of-care in Severe Trauma Patients at Risk of Acute Kidney Injury: a Multicenter Randomized Controlled Trial

Not applicable Interventional Hospices Civils de Lyon · NCT06834633

This trial tests whether giving an early nephroprotection bundle to adults with severe trauma and a urine biomarker showing kidney stress can reduce acute kidney injury.

What this trial studies

This interventional study enrolls adults with severe trauma (ISS >15) admitted within 6 hours who have an elevated urine NC score (>0.3) measured within 12 hours of ICU admission. Eligible patients are assigned to receive either standard care or a systematic nephrotection bundle-of-care initiated promptly after the biomarker result. The bundle follows guideline-recommended steps such as hemodynamic optimization, avoidance of nephrotoxins, and close urine/output and creatinine monitoring, applied early to try to stop reversible cellular kidney stress. Outcomes focus on preventing progression to acute kidney injury in the early post-trauma period and during the hospital stay.

Who should consider this trial

Good fit: Adults (≥18) with severe trauma (ISS >15) admitted to a participating trauma center within 6 hours who have an indwelling urinary catheter and an NC urine score >0.3 measured within 12 hours are the intended participants.

Not a fit: Patients already meeting clinical AKI criteria, those admitted more than 6 hours after injury, those without a urinary catheter, pregnant or breastfeeding patients, and those under legal restriction are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this approach could lower the number and severity of acute kidney injury episodes after severe trauma by enabling earlier protective care.

How similar studies have performed: Randomized trials in major surgical patients have shown early nephroprotection bundles can reduce severe AKI within 72 hours, but their application specifically in severe trauma patients is less well tested.

Eligibility criteria

Inclusion Criteria:

* Adult patient (≥ 18 years)
* Severe trauma patients (ISS score \> 15) admitted to a trauma center
* Time between trauma and admission to trauma center \<6h
* Patient with indwelling urinary catheter
