Summary

This study tracks the mental workload of anesthesia nurses during real surgeries at a hospital in Barcelona. Nurses fill out a short questionnaire three times per surgery to rate their mental, physical, and emotional demands. The goal is to see when they are most stressed and how factors like anesthesia type or surgery complexity affect their focus. No treatments are tested—just observation.

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 successful, this study could help identify which phases of anesthesia care are most mentally demanding, leading to better support for nurses and improved patient safety.
What could go wrong
This is a small, single-center observational study with only 50 participants, so results may not apply to other hospitals. It measures self-reported mental effort, not actual performance or patient outcomes.
