Summary
This study tests whether giving insulin or dexmedetomidine as a nasal spray before surgery can prevent early confusion and memory problems after coronary artery bypass grafting. The trial will enroll 150 adults aged 60 and older. Participants will receive one of the two nasal sprays or a placebo twice daily for two days before their operation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intranasal insulin or intranasal dexmedetomidine
- What this could lead to
- If it works, this could point toward a simple, low-cost way to prevent mental decline after heart bypass surgery.
- What could go wrong
- This is a very early (Phase 1) trial with only 150 people, so results may not be conclusive. The treatments might not work or could cause side effects like slow heart rate or cough.
