New monitor may help doctors give just the right amount of pain medicine during surgery
NCT ID NCT05615441
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special monitor that tracks pain signals during anesthesia can help doctors use less pain medicine during knee surgery. 54 adults having arthroscopic knee surgery were randomly assigned to receive either standard monitoring or the extra pain monitor. The goal was to see if the monitor led to lower pain medicine use and better pain control after surgery.
