Methadone Versus Placebo in Spine Fusion

April 21, 2015 updated by: Dhanesh Gupta, Northwestern University

The Effect of Methadone on Perioperative Analgesia After Posterior Lumbar Fusion - A Randomized, Placebo-controlled, Double-blinded Study

What is the influence of methadone on postoperative analgesia after lumbar interbody fusion in opioid naïve patients or patients who are taking less than equivalent of 15 mg IV morphine each day? What is the incidence of opioid related postoperative side effects after the administration of methadone in the operating room?

Study Overview

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.

Detailed Description

Hypothesis:

  1. We hypothesize that 0.2 mg/kg of methadone will result in decreased postoperative hydromorphone consumption compared to hydromorphone alone in opioid naïve patients or patients who are taking less than the equivalent of 15 mg IV morphine a day undergoing lumbar interbody fusion.
  2. We hypothesize that the incidence of opioid related postoperative side effects will not be increased by the administration of methadone in the operating room.

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.
Interventional

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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
