New Study: NOL Monitoring Can Help Reduce Postoperative Pain

A new study published in the British Journal of Anaesthesia (BJA) has found that monitoring pain response levels during surgery with NOL technology can help reduce postoperative pain. Exploring the potential use of NOL monitoring to help enhance recovery after surgery, the study demonstrated that patient pain scores after surgery were 33% lower when administration of pain medication during surgery was guided with NOL monitoring.

The new study followed 50 patients undergoing elective abdominal surgery in a two-center randomized controlled trial. The patients were randomly divided so that one group received NOL-guided analgesia dosing during the surgery and the control group received analgesics according to standard of care (based on hemodynamic monitoring). The study showed that while there was no increase in overall dosing in the NOL-guided group, the patients in that group reported less pain in the first 90 minutes compared to the control arm.  In addition, stress hormone levels (ACTH and cortisol) were on average 50% lower in the NOL-guided group, which clinically aligns with the lower pain response levels in those patients during surgery.

This study was led by Prof. Albert Dahan of Leiden University Medical Center’s Department of Anesthesiology.
