NCT06804434

Brief Summary

This prospective randomised clinical trial aims to assess the impact of intraoperative nociception monitoring using NOL on anesthetic management during major abdominal surgery. Additionally, the study will objectively evaluate using NOL how intravenous lidocaine administration, influences opioid requirements and the effect of this multimodal approach on early postoperative outcomes. The investigators hypothesize that NOL-guided intraoperative opioid administration reduces both intraoperative and postoperative opioid use, positively influencing 24-hour outcomes. Furthermore, the addition of intraoperative lidocaine in NOL-guided analgesia may further decrease opioid consumption.

Outcome Measures

Primary Outcomes (1)

  • Intraoperative opioid use

    We aim to examine the effect nociception level index monitoring in major abdominal surgery on intraoperative nociception management by measuring total opioid use in NOL monitored patients vs standard care according to the anesthesiologists judgement. Moreover, crossreference interventional arms will examine the effect of intraoperative administration of lidocaine in NOL and no NOL groups on intraoperative opioid use. Intraoperative opioid use will be time adjusted ( depending on the duration of surgery) and weight adjusted (depending on the weight of the patient)- mg of opioid/hour/kg
