About this study
Clinical studies are required to validate the hepatic NIRS monitor with other regional and global hemodynamic parameters and to evaluate its clinical use for continuous non-invasive hemodynamic monitoring. Using newer NIRS sensors the correlation between hepatic regional oxygen saturation and hepatic venous oxygen saturation (SvHO2) needs to be determined. If found to correlate then the NIRS can be used to evaluate early liver transplant failure and/or hepatic artery thrombosis, used as an early marker for shock, and necrotizing enterocolitis, and finally used in the outpatient setting to evaluate patients with chronic liver pathologies. If our validation study finds that NIRS monitors are an appropriate marker of hepatic venous saturation then it will lead to further clinical studies.

What is being measured
The primary outcome is the main question the study is designed to answer.
Degree of Hepatic Venous Saturation using NIRS
The investigators strive to discover a noninvasive measure of hepatic venous saturation. The use of NIRS monitoring for global oxygen saturation has been used in the inpatient population. This project aims to use hepatic NIRS monitor as a surrogate marker for hepatic and splanchnic oxygenation.
Measured: 5 minutes

Questions about this trial
What is this clinical trial studying?
An observational study of Congenital Heart Disease and Arrhythmia, run by Phoenix Children's Hospital 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 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 23 Jan 2026. 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?
Degree of Hepatic Venous Saturation using NIRS (time frame: 5 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 NCT01891188, which also lists 31 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 23 Jan 2026.
