New oxygen test could cut unnecessary blood transfusions after heart surgery

NCT ID NCT02761564

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether measuring oxygen levels in the blood (ScvO2) can help doctors decide when to give blood transfusions to anemic patients after heart surgery. 100 patients were randomly assigned to receive transfusions based on standard guidelines or only if their ScvO2 was low. The goal was to see if this approach reduces the number of transfusions without harming patients.

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 guided by ScvO2 measurement

What this could lead to

If successful, this approach could help doctors decide when to give blood transfusions after heart surgery, potentially reducing the number of transfusions and their risks.

What could go wrong

This is a small, early study with only 100 patients, so results may not apply to everyone. The ScvO2-guided strategy might not reduce transfusions or could miss patients who need blood.
