A tiny dose of an old drug might stop Post-Surgery brain fog in seniors

NCT ID NCT05401058

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This trial tests whether a single low dose of droperidol, given just before the end of surgery, can prevent postoperative delirium—a state of confusion and disorientation—in adults aged 65 and older undergoing non-cardiac surgery. About 800 participants will receive either droperidol or a placebo injection, and researchers will track delirium rates, severity, hospital stay, and cognitive function over six months. If it works, this could offer a simple preventive strategy to protect older patients' mental clarity after major operations.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
droperidol (a low-dose antipsychotic medication given by injection before the end of surgery)
What this could lead to
If effective, this could offer a simple, low-cost way to prevent postoperative delirium in older adults, potentially improving recovery and quality of life after surgery.
What could go wrong
The trial is still in progress, and results may not confirm a benefit. Droperidol can have side effects, including heart rhythm changes, and its use in this setting needs careful evaluation.
