Summary

This study tests whether giving children an amino acid infusion during and after heart surgery can lower their risk of acute kidney injury and reduce time on a ventilator. About 30 children at high risk will receive either the amino acid or a placebo for up to 72 hours. The goal is to see if this simple nutritional supplement can protect kidney function and speed recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Amino acid infusion (Trophamine 10%)
What this could lead to
If it works, this could point toward a simple, safe way to protect children's kidneys after heart surgery and reduce time on breathing machines.
What could go wrong
This is a small early-phase trial with only 30 children, so results may not be conclusive. The amino acid infusion may not reduce kidney injury or ventilator time compared to placebo.
