Brain oxygen drops may predict confusion after emergency surgery in seniors
NCT ID NCT03107260
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 181 elderly patients (65 and older) having emergency non-heart, non-lung surgery. Researchers measured brain oxygen levels during surgery and checked for confusion or memory problems (called postoperative cognitive dysfunction) up to 72 hours later. The goal was to see if drops in brain oxygen are linked to these thinking problems. The findings could help doctors monitor and potentially reduce cognitive risks in older surgical patients.
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 a clear link is found, it could help doctors monitor brain oxygen during surgery to reduce the risk of confusion or memory loss afterward.
What could go wrong
This is a completed observational study, not a treatment trial. It only looks for a relationship, so it cannot prove that changing oxygen levels would prevent cognitive issues.
