About this study

Official title: Comparison of Pain Relief During High Thoracic Erector Spinae Plane Block Using Different Volumes of Local Anesthetics

The primary endpoint of this study was to identify if the ESPB in the patients of cervical radiculopathy has the effect of pain relief. The secondary endpoint of this study was to identify the spread level in the craniocaudal direction when performed at the T2 level.

Read the detailed description

The ESPB requires ultrasound guidance which enables visible local anesthetic spread underneath the erector spinae muscles. The spinalis, longissimus thoracis, and iliocostalis muscles comprise the ES muscles, which run vertically along both sides of the vertebral column from the sacrum up to the skull base (1,10). The ESPB can be performed in the cervical, thoracic, and lumbar regions. Among them, upper or mid thoracic ESPB has been used more widely compared to cervical and lumbar regions.

Previous cadaveric studies on the ESPB at the T5 level using computed tomography (CT) reconstruction or direct dissection demonstrated the extensive craniocaudal distribution of methylene blue ranging from T1 to T8 vertebral segments deep to the ES muscles and variable involvement of epidural, paravertebral, and intercostal spaces. The ESPB performed at the T2 level of the cadaver demonstrated an injected dye distribution ranging from C4 to T10. Also, 36% of cadavers showed the spread of an injected dye to the ventral, dorsal ramus, paravertebral space, and even the contralateral side.

The exact mechanism of action of ESPB remains unclear. A recent study suggested that the analgesic effect of ESPB could be obtained by blocking the ventral and dorsal ramus of the spinal nerves by passing through the costotransverse foramen. However, in clinical practice, we can encounter highly variable clinical outcomes or sensory block after the ESPB. The study of the physical spread of the injected agent can be used to predict the clinical result and elucidate the possible mechanism of action of ESPB.

Questions about this trial

What is this clinical trial studying?

A study testing Erector spinae plane block in people with Pain, Chronic, run by Keimyung University Dongsan Medical Center 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 4 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 30 Mar 2023. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

numerical rating scale changes among 5 times period (time frame: baseline, 10 minutes after ESPB, 1 week after ESPB, 2 weeks after ESPB, 4 weeks after ESPB, 8 weeks after ESPB). The study lists 2 primary outcomes in all. 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 30 Mar 2023.
