Tranexamic Acid to Reduce Delirium After Gastrointestinal Surgery: the TRIGS-D Trial

This trial is testing whether tranexamic acid, a drug that reduces bleeding and inflammation, can lower the chances of delirium after major gastrointestinal surgery. Delirium is a sudden state of confusion common after surgery, especially in older adults, and it is linked to longer-term cognitive decline. This is a Phase 3 trial, meaning researchers are testing whether it actually works at scale — not just whether it is safe.
