Using NOL to guide pain management during laparoscopic surgery

Ιntraoperative Administration of Opioids Guided by the Nociception Level Index NOL in Elective Laparoscopic Surgeries Under General Anesthesia: Effect on Opioid Consumption, Post-operative Pain and Patient Recovery

Not applicable Interventional Attikon Hospital · NCT06104059

This study tests if using a special pain measurement tool can help adults having laparoscopic surgery use fewer opioids and recover better after their procedure.

What this trial studies

This clinical trial investigates whether the nociception level index (NOL) can effectively reduce opioid consumption in adult patients undergoing elective laparoscopic surgeries under general anesthesia. Patients will be randomly assigned to either an intervention group, where NOL is used to guide analgesia, or a control group receiving standard anesthetic care. The study aims to assess the impact of NOL on postoperative pain and recovery outcomes. Standard monitoring and anesthesia protocols will be followed for all participants.

Who should consider this trial

Good fit: Ideal candidates are adult patients over 18 years old scheduled for elective laparoscopic surgery under general anesthesia.

Not a fit: Patients who may not benefit include those undergoing emergency surgeries, pregnant individuals, or those with chronic pain or serious comorbidities.

Why it matters

Potential benefit: If successful, this approach could lead to reduced opioid use and improved recovery for patients undergoing laparoscopic surgery.

How similar studies have performed: Other studies have shown promise in using nociception monitoring to guide analgesia, suggesting potential for success in this approach.
