July 17, 2020 updated by: ismail aytaç, Ankara City Hospital Bilkent

Is Jedi Grip Efficient And Effective In Ultrasound Guided Peripheral Nerve Block: A Prospective, Randomized, Observer-Blinded Comparison Between Single And Double Operator Technique

In this prospective randomized controlled observer-blinded study we aimed to compare the efficacy of a single operator technique so called Jedi Grip and conventional technique requiring double operator in ultrasound guided axillary brachial plexus block.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Patients aged between 18 and 65 years, American Society of Anesthesiologists (ASA) physical status I to II ) undergoing elective hand, wrist and forearm surgery were prospectively enrolled. Patients were randomly assigned to Group C (conventional technique) or group J (Jedi technique). In both groups, axillary plexus blockage was provided by applying 5cc of a mixture of 10 cc 0.5% bupivacaine and 10 cc 2% prilocaine to the ulnar, radial, median and musculocutaneous nerves. Parameters such as performance time and the number of needle passes were recorded during procedure. Subsequently, a blinded observer evaluated and recorded parameters related to the success of blockage. The main outcome variable was performance time and success rate (surgical anesthesia).

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Group C
conventional two-operator axillary brachial plexus blockage
Procedure: conventional two-operator versus single operator using Jedi grip axillary brachial plexus blockage
on goup C, operator used the probe and needle with different hands while an assistant controlling the syringe to aspirate or inject local anesthetic. On Group J single operator controlled the probe with one hand while controlling the needle and the syringe on the other hand with the Jedi technique. The needle was held between the index finger and the middle phalanx of the middle finger, and the syringe was held with fingers 4 and 5, with the plunger part to the thumb in the palm.

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
block performance time
Time Frame: during procedure
the sum of imaging and needling times
during procedure
success rate
Time Frame: during operation
patients percentage with provided successful anesthesia
during operation

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
Measure Description
Time Frame
Onset time of sensory block
Time Frame: before operation
Sensory blockage was evaluated and graded; from lateral to the forearm, the volar face of the thumb, volar face of the 5th finger and lateral side of the hand back; for musculocutaneous, median, ulnar and radial nerves, respectively. Graduation was according to 3-point scale using a cold test: 0 = no block, 1 = analgesia (patient can feel touch, not cold), and 2 = anesthesia (patient cannot feel touch).
before operation
Onset time of motor block
Time Frame: before operation
Motor blockage was evaluated and graded; with elbow flexion, thumb abduction, thumb opposition, thumb adduction for musculocutaneous, radial, median, ulnar nerves respectively. Motor blockage graduation was also according to a 3-point scale: 0 = no block, 1 = paresis and 2 = paralysis.[
before operation
