Can tilting the bed improve pain detection in surgery?
NCT ID NCT02193412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether changing a patient's body position during surgery affects a device called the Analgesia Nociception Index (ANI), which is used to measure pain under anesthesia. Thirty neurosurgery patients were monitored as their bed was tilted head-up or head-down. The goal was to see if these position changes influenced the ANI readings, which could help anesthesiologists better assess pain in the future.
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 could help doctors better measure pain in patients under anesthesia, leading to more precise pain management during surgery.
What could go wrong
This is a small, early-stage study with only 30 participants. It focuses on a monitoring tool, not a treatment, so direct patient benefits are uncertain.
