About this study

Official title: A Magnetic Resonance Imaging Study of the Spread of Local Anesthetic Solution in Patients Receiving Ultrasound-guided Paravertebral Block at the Thoracic 2 Spinal Level: Prospective Randomized Controlled Study

The purpose of this study is to analyze the spread of local anesthetic using magnetic resonance imaging after thoracic 2 paravertebral block in patients with cervical radiculopathy.

Read the detailed description
  1. Ultrasound guided thoracic 2 paravertebral block will be done using sagittal scan or transverse scan.
  2. Clinical parameters will be monitored (temperature, perfusion index, assessment of sensory block and analgesic effect, vital sign, adverse events) after the nerve block.
  3. Cervical MRI will be taken 1 hour after the nerve block.
  4. Follow up 7 days and 28 days after the MRI at outpatient clinic (numeric rating scale, medication quantification scale)
Being tested
Ultrasound probe sagittal group, Ultrasound probe transverse group

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultrasound probe sagittal groupProcedure or surgery

    Place the ultrasound probe vertically against the patient's spine and insert the needle in-plane. The width of insertion of the needle is usually approximately 5 cm from the midline. After the needle penetrates the superior costovertebral ligament and pops, when it reaches the thoracic paravertebral space, perform aspiration and inject 10 mL of 1% lidocaine. At this time, it can be observed in real time as the infusion fluid pushes the bright pleura away from the needle.

  • Ultrasound probe transverse groupProcedure or surgery

    Place the ultrasound probe transverse to the spine and insert the needle in-plane. The reflection of a transverse process is a common landmark. The needle goes in from lateral to in plane. The goal is a triangle between the parietal pleura anteriorly and the internal intercostal membrane and intercostal muscle posteriorly. The final point of the needle is the transition zone from the intercostal to the thoracic paraspinal space, just anterior to the transverse process. When it is confirmed that the tip of the needle has reached the paravertebral space, 10 mL of 1% lidocaine is injected after checking the negative pressure, and after confirming the spread of the drug in real time with ultrasound.

What is being measured

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

  1. Injectate spread on MRI imge

    Presence of injectate on each anatomic target (Paravertebral space, ventral/dorsal epidural space, intercostal nerve, contralateral space)

    Measured: 1 hour after thoracic 2 paravertebral block

Secondary outcomes (8)
  1. numeric rating score

    A score of 0 indicates no pain and a score of 10 indicates maximum pain.

    Measured: Before nerve block, after 30 minutes, and thereafter, at the outpatient visit on the 7th day and the outpatient visit on the 28th day.

  2. perfusion index

    After the subject rests in the supine position for about 10 minutes, pulse oximetry is placed on the index finger to record the baseline value. Perfusion index was measured using pulse oximetry (Root®, Masimo Corporation, Irvine, CA, USA). The perfusion index can be a useful indicator for judging the After the subject rests in the supine position for about 10 minutes, pulse oximetry is placed on the index finger to record the baseline value. Perfusion index was measured using pulse oximetry (Root®, Masimo Corporation, Irvine, CA, )

    Measured: Before nerve block, after 30 minutes

  3. skin temperature

    Place a touch thermometer (IntelliVue MP70 patient monitor, Philips Healthcare, Best, Netherlands) on the palm of your hand and measure. Calculate the amount of change from the baseline. Record the difference with the contralateral hand.

    Measured: Before nerve block, after 30 minutes

  4. pinprick and cold test

    Pinprick sensation was performed using a 22 gauge short bevel needle. Comparison with the contralateral dermatome. Sensation is rated as 0 (no sensation), 1 (decreased sensation), and 2 (normal). A sensory block is considered successful if the patient reports 0 or 1. Cold sensation is measured in the same way using an ice cube. If there is no difference in the sensation of the treated dermatome compared to the contralateral dermatome.

    Measured: Before nerve block, after 30 minutes

  5. Blood pressure in mmHg

    Record blood pressure , and calculate the change from baseline.

    Measured: Before nerve block, after 30 minutes

  6. Pulse rate in /min

    Record pulse, and calculate the change from baseline.

    Measured: Before nerve block, after 30 minutes

  7. Presence of adverse events

    Horner syndrome, hoarseness, dyspnea, ptosis, dysphagia

    Measured: Before nerve block, after 30 minutes

  8. medication quantification scale

    The Medication Quantification Scale (MQS) is an instrument with potential clinical and research applications for quantifying medication regimen use in chronic pain populations.

    Measured: Before nerve block, and thereafter, at the outpatient visit on the 7th day and the outpatient visit on the 28th day

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound probe sagittal group and Ultrasound probe transverse group in people with Cervical Spinal Stenosis, run by Gangnam Severance Hospital at 1 site in South Korea.

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 4 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 2 Dec 2021. 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 South Korea. 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?

Results are not available in the source record.

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

Contact Do Hyeong Kim (82-2-2019-4601, BREADFANS@yuhs.ac), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Injectate spread on MRI imge (time frame: 1 hour after thoracic 2 paravertebral block). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Dec 2021.
