Impact of Intraoperative Non-invasive Analgesia Monitoring Using Nociception Level Index on Patient Management

January 27, 2025 updated by: Osoian Cristiana
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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Intraoperative opioid use
Time Frame: intraoperative
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
intraoperative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
