A Comparison of the Clinical Outcomes of Minimum and Maximum Hematocrit Levels During Cardiopulmonary Bypass (CPB) in Low-risk Patients Undergoing Coronary Artery Bypass Graft Surgery (CABG): A Cross-sectional Study
This cross-sectional study explores the clinical outcomes of minimum and maximum hematocrit (HCT) levels during cardiopulmonary bypass (CPB) in low-risk coronary artery bypass graft (CABG) surgery patients. It found that lower HCT levels (16-18%) resulted in significantly less post-surgery drainage and lower incidence of cognitive disorders compared to higher HCT levels (25-27%), which required more transfusions of packed red blood cells and fresh frozen plasma, leading to an increased risk of cognitive impairments.
