Association of Near Infrared Spectroscopy With Interstage Outcomes

Association of Renal Near Infrared Spectroscopy in Outpatients With Parallel Circulation During the Interstage Period and Interstage Morbidity

The purpose of this study is to assess the utility of renal near infrared spectroscopy in the outpatient setting during the interstage period. The primary aim will be to determine the correlation between oxygen extraction ratio ((arterial pulse oximetry - renal near infrared spectroscopy value)/arterial pulse oximetry value) with need for inpatient admission or intervention. Secondary aims will be to determine the correlation of the oxygen extraction ratio with weight gain, neurodevelopment, unexpected admissions, systemic ventricular strain by echocardiography, and Glenn hospitalization admission characteristics.

As above

Inclusion Criteria:

• Infants under 6 months of age
• Infants with single ventricle heart disease and parallel circulation
• Infants who are awaiting the Glenn operation
• Infants who are outpatient

Exclusion Criteria:

• Infants over 6 months of age
• Inpatients
• Infants with history of skin injury from the near infrared spectroscopy sensor inpatient
• Infants with ongoing hyperbilirubinemia
