Indexed Delivery of Oxygen Predicts In-hospital Mortality and Morbidity in Reoperative Adult Cardiac Surgery Patients: A Retrospective Cohort Study
Abstract
OBJECTIVES: To evaluate the association between intraoperative indexed oxygen delivery (DO₂i) during cardiopulmonary bypass (CPB) and postoperative outcomes in patients undergoing reoperative cardiac surgery. DESIGN: Retrospective cohort study. SETTING: A tertiary academic cardiac surgery center. PARTICIPANTS: A total of 343 patients who underwent reoperative cardiac procedures between January 2011 and January 2021. INTERVENTIONS: Patients were stratified by the median DO₂i threshold predictive of in-hospital mortality, identified using Youden's Index. MEASUREMENTS AND MAIN RESULTS: Median DO₂i was 300.8 ± 52.3 mL/min/m². In-hospital mortality was 14.6%. A median DO₂i
