Poor sleep before surgery may slow anesthesia recovery, study hints
NCT ID NCT07675993
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study investigates whether people with sleep disorders before noncardiac surgery take longer to wake up from anesthesia and have a lower quality recovery. Researchers will monitor brain activity during and after surgery in 80 adults, comparing those with poor sleep to those with good sleep. The goal is to understand how sleep health influences anesthesia depth and emergence, which could help personalize anesthesia care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If sleep problems are shown to slow anesthesia recovery, this could lead to better preoperative sleep screening and tailored anesthesia plans.
- What could go wrong
- This is a small observational study, so it cannot prove cause and effect. Results may not apply to all surgery types or patient groups.
