Is Near Infrared Spectroscopy An Accurate Marker Of Low Cardiac Output After Stage 1 Palliation In Single Ventricle Patients?

Abstract

Background: Balancing the systemic and pulmonary circulation during the early postoperative period is paramount in the management of children who have physiology compatible with single ventricle parallel circulation after stage 1 palliation. Near-infrared spectroscopy (NIRS) is a non-invasive, continuous method of evaluating real-time regional oximetry. Previous studies have shown a moderate correlation between cerebral near-infrared spectroscopy (cNIRS) and other markers of low cardiac output, although, there is a paucity of data in patients with single ventricle parallel physiology. Methods: Retrospective chart review including children with single ventricle parallel physiology who underwent stage 1 palliation between January 2010 and December 2019 in our institution.
