Summary

This study looks at how different low-flow rates of the anesthesia gas desflurane affect brain activity and thinking skills in adults having major abdominal surgery. Researchers will monitor brain waves during surgery and test memory and attention within 24 hours after the operation. The goal is to find out which low-flow strategy is safest for mental recovery.

What this could mean

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

Active substance
desflurane
What this could lead to
If successful, this could help anesthesiologists choose safer low-flow anesthesia settings that preserve patients' memory and attention after major surgery.
What could go wrong
This is a small, early-stage study with only 72 participants, so results may not apply to all patients. It looks at short-term cognitive changes, not long-term outcomes.
