Intelligent Needle Tip Tracking Using Ultrasound Imaging for Infraclavicular Brachial Plexus Blocks

October 26, 2018 updated by: Axel Rudolf Sauter, Oslo University Hospital
In a randomized controlled crossover study design, ultrasound guided infraclavicular brachial plexus blocks will be performed with and without the aid of a needle tip tracking (NTT) system. Specialists in anaesthesiology with average experience in ultrasound guided PNB techniques will perform the blocks. 26 volunteers will be included. The primary objective is to investigate the effect of the NTT system on performance time, as a measure for improved block performance. Secondary objectives are the effects of the NTT system on dexterity, peripheral nerve block characteristics, subjective experience, and peripheral block performance.

Study Overview

Status

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.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
26

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

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
Performance time
Time Frame: During peripheral nerve block procedure
Performance time is defined as the time from insertion of the block needle (skin puncture) until finishing LA injection
During peripheral nerve block procedure

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
Distance travelled by needling hand
Time Frame: During peripheral nerve block procedure
Measured by motion analysis from insertion of the block needle (skin puncture) until finishing LA injection
During peripheral nerve block procedure
Distance travelled by probe hand
Time Frame: During peripheral nerve block procedure
Measured by motion analysis from insertion of the block needle (skin puncture) until finishing LA injection
During peripheral nerve block procedure
Number of intended movements (needling hand)
Time Frame: During peripheral nerve block procedure
Measured by motion analysis from insertion of the block needle (skin puncture) until finishing LA injection
During peripheral nerve block procedure
Number of intended movements (probe hand)
Time Frame: During peripheral nerve block procedure
Measured by motion analysis from insertion of the block needle (skin puncture) until finishing LA injection
During peripheral nerve block procedure
Block success
Time Frame: 30 minutes after peripheral nerve block procedure
A sensory block is defined as successful when there is analgesia (no sensation for touch) or anaesthesia (no sensation at all) involving all five nerves distal to the elbow
30 minutes after peripheral nerve block procedure
Block duration
Time Frame: Within 240 minutes after peripheral nerve block procedure
Block duration is the time from the end of LA injection until at least one of the nerves involved in the sensory block has recovered
Within 240 minutes after peripheral nerve block procedure
Quantified discomfort during block performance
Time Frame: Immediately after peripheral nerve block procedure
The participants are asked about discomfort during the block procedure using a numeric rating scale (scale range 0 - 10; 0 = no discomfort; 10 = worst discomfort imaginable)
Immediately after peripheral nerve block procedure
Confidence in block success
Time Frame: Immediately after peripheral nerve block procedure
The anaesthetist is asked if he expects the block to be successful using a numeric rating scale (scale range 0 - 10; 0 = block success unlikely; 10 = block success very likely)
Immediately after peripheral nerve block procedure
Block onset time
Time Frame: Within 60 minutes after peripheral nerve block procedure
Block onset time is defined as the time between the end of LA injection and development of a successful sensory block
Within 60 minutes after peripheral nerve block procedure
