NCT ID NCT07673510
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study looks at whether certain antibiotics given before surgery are linked to postoperative delirium in adults over 65 having elective non-cardiac surgery. Researchers will track antibiotic use and check for delirium twice daily. The goal is to provide safety evidence to guide antibiotic choices and help prevent confusion after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
perioperative antibiotics (beta-lactams, nitroimidazoles, glycopeptides, fluoroquinolones, and others)
What this could lead to
If a link is found, surgeons may choose safer antibiotics to reduce delirium risk in older patients.
What could go wrong
This is an observational study, so it can show an association but not prove cause. Results may not apply to all surgery types or hospitals.
