About this study

Official title: Incidence of Inadvertent Intercostal or Epidural Spread During Thoracic Sympathetic Ganglion Block

This study wants to identify the incidence of inadvertend intercostal or epidural spread of thoracic sympathetic block

Read the detailed description

Clinically, sympathetic blocks (SB) have been used widely to relieve the symptoms of SMP or to differentiate between SMP and sympathetically independent pain. In order to an SB has a diagnostic value, it requires the successful disturbance of the sympathetic activity for a proper duration of time.

For the diagnosis of SMP using an SB, it is essential achieving complete interruption of the sympathetic activity while preserving the sensory and motor function. The sympathetic trunk at lumbar region runs on the anterolateral surface of the vertebral column from L1 to L4 levels, and deep to the medial aspect of the psoas major muscle. Therefore, the investigators can hardly find epidural contrast spread during lumbar SB due to an anterior location of lumbar sympathetic ganglion to the lateral vertebral body. However, frequent psoas muscle injection can be encountered due to a close proximity of lumbar sympathetic ganglion.

In contrast to lumbar sympathetic ganglion, the thoracic sympathetic ganglion is not separated from somatic nerves by muscles and connective tissue. Moreover, the upper thoracic ganglion runs on the posterior surface of vertebral column with close proximity to adjacent epidural region.

This difference of thoracic sympathetic ganglion leads to a frequent epidural and intercostal spread if the investigators perform thoracic SB. Such spread to epidural and intercostal space lowers the diagnostic value of thoracic SB. In addition, serious adverse outcome can be encountered if neurolytic agent is injected into epidural or intercostal space for the purpose of thoracic sympathectomy. Considering the diagnostic value and safety of thoracic SB, evaluation of actual incidence of occurrence of intercostal and epidural spread is important.

What is being measured

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

  1. incidence of intercostal spread

    intercostal spread which appears at fluorosopic view after contrast medium injection

    Measured: 60 seconds after the completion of thoracic sympathetic ganglion block. 60 seconds means the time when the outcome was measured after thoracic sympathetic ganglion block

  2. incidence of epidural spread

    epidural spread which appears at fluorosopic view after contrast medium injection

    Measured: 60 seconds after the completion of thoracic sympathetic ganglion block. 60 seconds means the time when the outcome was measured after thoracic sympathetic ganglion block

Secondary outcomes (1)
  1. degree of finger tip skin temperature increase

    Skin temperature measurement which is observed after successful sympathetic block

    Measured: 5, 10, 15, 20 minutes after the completion of the intervention 5, 10, 15, 20 minutes mean the time that the outcome was measured after performing the intervention

Questions about this trial

What is this clinical trial studying?

An observational study of Thoracic; Sympathetic Ganglion, Injury, run by Keimyung University Dongsan Medical Center at 2 sites 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 2 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 20 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

incidence of intercostal spread (time frame: 60 seconds after the completion of thoracic sympathetic ganglion block. 60 seconds means the time when the outcome was measured after thoracic sympathetic ganglion block). 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 20 Sep 2019.
