Can ultrasound prevent fluid overload in kidney patients?
NCT ID NCT06411080
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested whether using ultrasound to check fluid tolerance is feasible in hospitalized patients with acute kidney injury (AKI). 80 non-ICU adults were randomly assigned to receive either standard care or an ultrasound-guided fluid assessment. The main goal was to see if doctors could follow the ultrasound protocol. Secondary goals looked at fluid amounts, diuretic use, and kidney function changes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Point-of-care ultrasound (POCUS) for fluid tolerance assessment
- What this could lead to
- If successful, this approach could help doctors give fluids more safely to kidney injury patients, potentially reducing complications.
- What could go wrong
- This is a small pilot study focused on feasibility, not on proving better outcomes. The results may not change practice without larger trials.
