Trial summary

The aim of this prospective observational study is to assess whether transesophageal echocardiography (TEE) can be used to identify the structures within the vertebral foramen of the spinal column and to determine the range of spinal segments which can be visualized. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: All age population going under cardiac surgery

Who may be able to join

  • patients scheduled for cardiothoracic or interventional cardiac surgeries under general anesthesia

Who cannot join

  • We will exclude any patients with known esophageal abnormalities, lesions or disease that would disqualify the patient for the use of TEE as standard procedure.
  • We will also exclude any patients that come to the catheter laboratory exclusively for TEE exam as our study will only occur in patients already scheduled to undergo TEE use in surgery or diagnostic procedure.

Read the detailed description

The aim of this prospective observational study is to assess whether transesophageal echocardiography (TEE) can be used to identify the structures within the vertebral foramen of the spinal column and to determine the range of spinal segments which can be visualized. Data will be collected from both pediatric and adult patients undergoing cardiothoracic and interventional cardiac surgeries under general anesthesia. Because use of TEE is a standard surgical procedure and because TEE will already be in place to visualize the heart, no additional processes will be required to collect data, minimizing patient risk. TEE will be monitored and controlled by a trained anesthesiologist or TEE technician and visualization of the spinal cord will be confirmed. Real-time TEE images will then be captured and later graded by a trained sonographer as high, medium or low quality. Starting at the level of the tracheal bifurcation, corresponding to thoracic vertebral level T5 (Mirajalili 2012), the TEE probe will be advanced cranially to determine the spinal levels visualized above T5 and caudally in order to determine the spinal levels below T5 that can be seen on TEE. At each level seen on TEE, pictures will be taken for confirmation.

Questions about this trial

What is this clinical trial studying?

An observational study of Spinal Cord and Epidural, run by Kenichi Ueda 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 1 inclusion and 2 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 22 Jan 2020. 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 23 Oct 2019). 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?

Number of Thoracic Spinal Segments Successfully Visualized With TEE (time frame: within 30 minutes). 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 NCT02415244, which also lists 4 linked publications.

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 22 Jan 2020.
