Near-Infrared Spectroscopy Comparison Study
An observational study of Total Aortic Arch Replacement, run by Nonin Medical, Inc at 1 site in United States.
Trial summary
The objective of this study is to validate Near-Infrared (NIRS) monitoring in patients undergoing circulatory arrest. This study will compare two-wavelength NIRS INVOS System, Somanetics; Troy, MI) with four-wavelength NIRS (Nonin Medical, Inc; Plymouth, MN) to determine which modality best correlates with jugular… Read more about this study

About this study
Official title: Validation of Near-Infrared Spectroscopy for Neuromonitoring During Moderate Hypothermic Circulatory Arrest for Total Aortic Arch Replacement: A Comparison of Two Technologies With Jugular Venous Bulb Oximetry
The objective of this study is to validate Near-Infrared (NIRS) monitoring in patients undergoing circulatory arrest. This study will compare two-wavelength NIRS INVOS System, Somanetics; Troy, MI) with four-wavelength NIRS (Nonin Medical, Inc; Plymouth, MN) to determine which modality best correlates with jugular venous oxygen saturation

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Cardiac Disease | Total Aortic Arch Replacement |
What is being measured
The primary outcome is the main question the study is designed to answer.
Linear correlation between absolute value of cerebral oxygen saturation (rSO2) compared to Jugular Venous Oxygen Saturation (SjvO2). Sensitivity and specificity to detect < 60% desaturation.
Measured: At the end of the surgical case approximately 6 to 8 hours

Questions about this trial
What is this clinical trial studying?
An observational study of Total Aortic Arch Replacement, run by Nonin Medical, Inc 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 6 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 21 May 2012. 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?
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?
Linear correlation between absolute value of cerebral oxygen saturation (rSO2) compared to Jugular Venous Oxygen Saturation (SjvO2). Sensitivity and specificity to detect < 60% desaturation. (time frame: At the end of the surgical case approximately 6 to 8 hours). 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 21 May 2012.
