Cerebral Oxygen Saturation Does Not Normalize Until After Stage 2 Single Ventricle Palliation

In children with single ventricle physiology, Sco2 decreases after initial palliation, remains low before second-stage palliation, but is normal before and after the Fontan. This has implications for perioperative mortality, neurologic injury, and potentially for interim mortality. Low postoperative Sco2 predicts perioperative mortality.
