Predictive Role of Cardiopulmonary Bypass Exposure Indexed to Body Surface Area on Postoperative Organ Dysfunction: A Retrospective Cohort Study
This study analyzed the relationship between cardiopulmonary bypass (CPB) exposure indexed to body surface area (bypass index) and postoperative outcomes in 2,413 cardiac surgery patients. A higher bypass index was predictive of increased hospital stay and organ dysfunction, particularly renal and cardiac rhythm issues, but not pulmonary dysfunction. These findings highlight the bypass index as a valuable metric for assessing risk and optimizing resource use during cardiac surgery.
