Analgesia Nociception Index in Orthognathic Surgery

January 12, 2024 updated by: Eun-hee Kim, Seoul National University Hospital

Comparison of Goal-directed Analgesia Using ANI (Analgesia/Nociception Index) and Standard Analgesia During General Anesthesia in Patients Undergoing Orthognathic Surgery on Postoperative Quality of Recovery: a Prospective Randomized Controlled Trial

This study aims to determine whether goal-directed analgesia using ANI(Analgesia/Nociception Index) can improve the quality of postoperative recovery in patients undergoing maxillofacial surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

intraoperative analgesia was provided by infusion of remifentanil via target controlled infusion mode, which was controlled according to the clinician's decision
Experimental: goal-directed analgesia using ANI monitoring
Device: Analgesia/Nociception Index (ANI) monitoring
intraoperative analgesia was provided by infusion of remifentanil via target controlled infusion mode, which was controlled according to ANI monitor.

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
Postoperative QoR-15K score
Time Frame: 24 hours after the end of surgery
Korean-translated QoR-15K (15-item Quality of Recovery (QoR-15) scale, minimum 0, maximum 150, higher scores mean a better outcome ) scores assessed by participants blinded to arm assignment 24 hours after surgery.
24 hours after the end of surgery

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.
