Anemia's hidden impact on blood flow during surgery revealed
NCT ID NCT07583927
First seen May 20, 2026
Summary
This study looks at how anemia changes blood flow in the smallest blood vessels (microcirculation) in patients having open surgery for gastric cancer. Researchers will compare 27 anemic patients with 27 non-anemic patients, all receiving standard goal-directed fluid therapy. They will use a special camera to view blood vessels under the tongue at four points during surgery. The goal is to see if anemia causes measurable differences in vessel density and blood flow, which could help guide future care.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could help doctors better understand how anemia affects blood flow in small vessels during surgery, potentially improving fluid management for anemic patients.
What could go wrong
This is a small, early observational study with only 54 participants. It does not test any treatment, so it cannot directly lead to new therapies. Results may not apply to other surgeries or patient groups.
