Could moving the operating table skew brain monitors?
NCT ID NCT07013734
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This observational study looks at whether changing a patient's body position during surgery affects brain monitoring values in people under general anesthesia. Researchers will track brain activity, pain response, and brain oxygen levels while briefly moving the operating table into two positions. The goal is to see if these position changes alter the monitor readings, which could help improve how anesthesia depth is measured. Participants will also answer a short questionnaire about their memories before and after anesthesia.
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 positioning affects these monitors, it could lead to more accurate anesthesia monitoring and better patient safety during surgery.
- What could go wrong
- This is a small observational study, so it may not capture all factors. Results may not apply to all patients or surgeries, and the monitors' readings could vary for other reasons.
