Can better training for anesthesia teams save lives after surgery?
NCT ID NCT06111248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether training healthcare teams to use special monitoring tools during general anesthesia could reduce complications and deaths after non-cardiac surgery. Over 1,000 patients were included, and the training focused on tools that track pain, brain activity, and muscle relaxation. The goal was to see if better use of these tools improves patient outcomes within 28 days 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
- Staff training on using surgical plethysmographic index, state entropy, train-of-four monitors, and AoA software
- What this could lead to
- If successful, this training approach could reduce serious complications and deaths after surgery by helping anesthesia teams better monitor patients.
- What could go wrong
- This is a single-center before/after study, not a randomized trial, so results may not apply to other hospitals. The training itself has no direct risks, but the study cannot prove cause and effect.
