Structured retrospective recording of quality assurance measures of the nociception level index (NOL) during surgical interventions

Nociceptive monitoring using the NOL® system during intracerebral and abdominal surgery is feasible and might yield helpful information to support therapeutic decisions. This could help to reduce hyperanalgesia, facilitating shorter emergence periods and less postoperative complications. Prospective clinical studies are needed to further examine the potential benefits of this monitoring approach in a neurosurgical context.
