The Influence of Intravenous Lidocaine on the Action of the Neuromuscular Blocker Rocuronium (LidoRoc)

July 14, 2011 updated by: University Hospital, Geneva

The Effect of Intravenous Lidocaine on the Time Course of Rocuronium Induced Neuromuscular Block. A Randomised, Placebo-controlled, Electrophysiological Study

Lidocaine is a local anesthetic which is widely used in daily anesthesia and surgical practice. It has been shown that intravenous lidocaine given during an operation has analgesic properties. Finally intravenous lidocaine is inexpensive and easy to administer and safe if non-toxic doses are respected. It is likely that the use of lidocaine infusions during anesthesia might increase in the coming years. Neuromuscular blockers (curare like substances) are used in anesthesia to facilitate tracheal intubation and to achieve muscle relaxation and immobility during surgery. Rocuronium is one of the most widely used neuromuscular blocking agents. Local anesthetics, such as lidocaine, are known to potentiate the effect of neuromuscular blocking agents. In the study the investigators want to evaluate the effect of intravenous lidocaine during the operation on the time course of the rocuronium-induced neuromuscular block. A secondary aim is to evaluate intubation conditions (lidocaine has been shown also to improve intubation conditions) and safety.

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.

Study Type

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 60 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Placebo Comparator: Placebo
Drug: Placebo
Immediately before induction, patients will receive 0.15 ml kg-1 of the study drug as an intravenous bolus followed, after tracheal intubation, by a continuous intravenous infusion of 0.2 ml kg-1 h-1. In the Placebo group this will be physiologic saline. The infusion will be stopped after complete recovery from the neuromuscular block.
Active Comparator: Lidocaine
Drug: Lidocaine
Immediately before induction, patients will receive 0.15 ml kg-1 of the study drug as an intravenous bolus followed, after tracheal intubation, by a continuous intravenous infusion of 0.2 ml kg-1 h-1. In the lidocaine Arm this regimen corresponds to 1.5 mg kg-1 lidocaine bolus injection and 2 mg kg-1 h-1 lidocaine continuous infusion. The infusion will be stopped after complete recovery from the neuromuscular block.
Other Names:
  • Rapidocaïne®
  • Xylocain®

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
Time Frame
Onset and recovery of the neuromuscular block
Time Frame: From start of injection of rocuronium until TOF 90%
From start of injection of rocuronium until TOF 90%

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.
Outcome Measure
Time Frame
To evaluate intubation conditions at T1, we will use the scale according to the Good Clinical Research practice (GRCP) in neuromuscular research
Time Frame: 2 to 3 minutes
2 to 3 minutes
Any minor adverse event (no need for intervention) or major adverse event will be recorded.
Time Frame: up to 5 hours
