Can less be more? testing transfusion limits in ECMO

NCT ID NCT06560164

First seen Aug 14, 2026 · Last updated Aug 14, 2026

Summary

This trial asks whether a restrictive red blood cell transfusion strategy is as safe as a liberal one for adults on ECMO, a life-support machine for heart or lung failure. Patients will be randomly assigned to receive transfusions only when their hemoglobin drops to 7.0 g/dL (restrictive) or 9.0 g/dL (liberal). The main goal is to compare 90-day survival rates between the two groups.

What this could mean

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

Active substance
Red blood cell transfusion
What this could lead to
If a restrictive transfusion strategy proves non-inferior, it could reduce transfusion-related risks and costs for ECMO patients, potentially improving outcomes.
What could go wrong
This is a non-inferiority trial, so it may show that restrictive transfusions are not as safe. Transfusions themselves carry risks, and the trial's results may not apply to all ECMO patients.
