New finger sensor aims to reduce blood transfusions in surgery
NCT ID NCT02986789
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a special finger sensor that measures hemoglobin and fluid levels without needles during surgery. The goal was to see if this real-time information helps doctors decide when to give blood transfusions, potentially reducing the amount of donor blood needed. The study included 43 adults undergoing major surgeries with expected blood loss, but it was terminated early, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Pulse oximeter finger sensor (noninvasive hemoglobin and pleth variability index monitoring)
- What this could lead to
- If successful, this could help doctors make better decisions about blood transfusions during surgery, potentially reducing the need for donor blood.
- What could go wrong
- The study was terminated early with only 43 participants, so results are limited. The device may not improve outcomes for all surgical patients.
