Can better brain monitoring during surgery prevent confusion afterward?
NCT ID NCT04978558
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two non-invasive methods (NIRS and TCD) to monitor how well the brain controls its own blood flow during major non-cardiac surgery. The goal was to see which method works better and whether keeping blood pressure in a certain range can reduce the risk of confusion or memory problems after surgery. 509 adults having elective surgery with expected blood loss over 500 ml took part.
