About this study

Official title: Near Infrared Spectroscopy Monitoring of Cerebral Oxygen Saturation in Neonatal Cardiac Surgery - Comparison With Common Methods of Estimating Adequate Systemic Perfusion

Due to the small size of infants and the use of bypass machines, physicians have difficulty assessing whether the infant's brain and body is getting enough oxygen during heart surgery. This study compares continuous monitoring via the NIRS (Near Infrared Spectroscopy) to the traditional methods of determining oxygen saturation.

Read the detailed description

One of the limiting factors in treating infants undergoing cardiac surgery is the difficulty in assessing systemic perfusion with accuracy. At Children's Healthcare of Atlanta, Near-infrared Spectroscopy (NIRS) is available, but has never been studied. In patients undergoing first stage palliation (Norwood) for hypoplastic left heart, routine management will be utilized in addition to the NIRS monitor. The following will be documented pre- and post-bypass, then every 4 hours for 24 hours after admission to the Cardiac Intensive Care Unit:NIRS readings, Lactic acid levels,mixed venous saturations,hemoglobin, hematocrit, arterial blood gases, heart rate, blood pressure, central venous pressure, left atrium pressure,core temperature, toe temperature, pulse oximeter reading, urine output, ventilator settings, inotropic levels. All the data will be entered into a database and analyzed.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoplastic Left Heart and Surgery, run by Emory University 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 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?

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00166101, which also lists 10 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 14 Nov 2012.
