BACKGROUND: Near-infrared spectroscopy (NIRS) is used routinely to monitor cerebral tissue oxygen saturation (SctO2) during cardiopulmonary bypass (CPB) but is rarely employed outside the operating room. Previous studies indicate that patients are at risk of postoperative cerebral oxygen desaturation after cardiac surgery. OBJECTIVES: We aimed to assess perioperative and postoperative changes in NIRS-derived SctO2 in cardiac surgery patients. DESIGN: Prospective observational study. SETTING: The study was conducted in a tertiary referral university hospital in Australia from December 2017 to December 2018. PATIENTS: We studied 34 adult patients (70.6% men) undergoing cardiac surgery requirin..View full abstract
