About this study

Official title: Effect of InfinitiPlusTM Needle Guidance in Ultrasound Guided Regional Anesthesia

An FDA-approved product, InfinitiPlus (TM), is a needle guidance system that has been recently developed to guide clinicians in performing ultrasound guided nerve blocks. This system helps the clinician to align the needle with ultrasound beam while performing an ultrasound guided nerve block. InfinitiPlus (TM) has a unique open channel design allowing efficient needle movement while having improved needle shaft and tip visualization. This is a disposable system specifically designed for improving success rate of ultrasound guided block and patient safety.

This study will be done with patients having elective knee surgery and a femoral nerve block with a catheter. The nerve block procedure will be performed under ultrasound guidance to help improve safety and efficacy of the injection. InfinitiPlus (TM) has been recently developed to try to improve needle guidance in the ultrasound guided nerve block procedure. This study will determine whether femoral nerve block procedures performed under ultrasound guidance with InfinitiPlus (TM) take less time than procedures performed with ultrasound guidance and a conventional block needle. The study will also determine whether the InfinitiPlus (TM) needle reduces the number of times the clinician attempts the procedure, reduces the cost of the procedure, increases the procedure success rate, and improves ultrasound visibility of the needle.

Participants will be randomly assigned to either ultrasound guidance with the InfinitiPlus (TM) needle guidance system or ultrasound guidance with a conventional block needle. After surgery, pain will be rated every 30 minutes for the first 2 hours, then every 4 hours while awake for 24 hours. 24 hours after surgery, participants will be given a survey about pain treatment satisfaction and a questionnaire about recovery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time Spent in Performing Ultrasound Guided Femoral Nerve Blocks With InfinitiPlusTM Needle Guidance System

    Measured: time elapsed from beginning the block procedure (after prepping and draping) until the catheter was successfully inserted or the end of the day of surgery.

Secondary outcomes (3)
  1. Block Failure

    Number of patients who had block failure

    Measured: start of surgery until femoral nerve block completion

  2. > 1 Block Attempt

    Number of block attempts was collected for each patient as > 1 block attempt versus 1 attempt. A block attempt was defined as pulling the block needle back to skin and redirecting it.

    Measured: from start of block procedure until block placement

  3. Percentage of Time With Perfect Needle Visibility

    Percentage of time that perfect needle visibility was visualized on ultrasound.

    Measured: From start of block procedure until block placement

Questions about this trial

What is this clinical trial studying?

A study testing Infiniti Plus needle guidance system and Conventional block needle in people with Elective Knee Surgery, run by The Cleveland Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time Spent in Performing Ultrasound Guided Femoral Nerve Blocks With InfinitiPlusTM Needle Guidance System (time frame: time elapsed from beginning the block procedure (after prepping and draping) until the catheter was successfully inserted or the end of the day of surgery.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02080481, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2017.
