New kidney machine for tiny tots under scrutiny
NCT ID NCT04608149
First seen Jun 24, 2026 · Last updated Sep 15, 2026 · Updated 3 times
Summary
This study follows about 36 children weighing 2.5-10 kg who have acute kidney injury or fluid overload and are treated with the Carpediem continuous renal replacement therapy system. Researchers will track survival, kidney recovery, and hospital stay lengths to see how well the device works in real-world intensive care settings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Carpediem™ system (continuous renal replacement therapy device)
- What this could lead to
- If successful, this study could confirm that the Carpediem system is safe and effective for treating kidney injury and fluid overload in small children.
- What could go wrong
- This is an observational study with no control group, so it cannot prove the device works better than other treatments. Results may not apply to all children.
