About this study

An observational study designed to evaluate the performance of a new Near Infrared Spectroscopy (NIRS) tissue oximeter device in the clinical setting, including a cerebral sensor and peripheral sensor. Fifty patients who are undergoing open-heart surgery will be enrolled and tissue oximetry measurement will be collected throughout the surgical procedure and for up to 24 hours following surgery. Tissue oximeter measurement of the brain and skeletal tissue will be added to the standard intra-operative patient monitoring. Measures of delirium will be collected using a standardized questionnaire. The relationship between cerebral oximetry measures and delirium scores will be explored.

What is being measured

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

  1. Percent of time Regional Oxygen Saturation (rSO2) values are registered during open heart surgery.

    Measured: Completion of cardiovascular surgery

Secondary outcomes (1)
  1. Correlation between delirium outcome scale and Regional Oxygen Saturation (rSO2) values.

    Measured: Patient discharge (on average 7 days)

Questions about this trial

What is this clinical trial studying?

An observational study of Heart; Dysfunction Postoperative, Cardiac Surgery, 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 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?

Percent of time Regional Oxygen Saturation (rSO2) values are registered during open heart surgery. (time frame: Completion of cardiovascular surgery). 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.
