Retained Blood Syndrome Is Associated With High Mortality and Morbidity After Cardiac Surgery
This large retrospective study found retained blood syndrome (RBS) occurred in 12.7% of cardiac surgery patients and was associated with significantly higher short‑ and long‑term mortality, morbidity, and prolonged ICU and hospital stay. RBS was linked to increased atrial fibrillation, acute kidney injury, and infections. The findings highlight the critical importance of effective postoperative bleeding control and chest drain management to minimize retained blood and improve outcomes after cardiac surgery.
