Hemoadsorption does not Have Influence on Hemolysis During Cardiopulmonary Bypass

Cardiopulmonary bypass (CPB) induces hemolysis, which manifests as plasma free hemoglobin. We investigated in a post hoc analysis of a single-center, blinded, controlled study whether the use of a novel hemoadsorption device (CytoSorb, CytoSorbents Europe GmbH, Berlin, Germany) affects hemolysis during CPB. A total of 35 patients undergoing elective CPB surgery with an expected CPB duration of more than 120 min were included in the analysis. The hemoadsorption device was used in 17 patients (intervention group) and not used in 18 patients (control group). The primary outcome was differences of postoperative free hemoglobin and haptoglobin levels. As secondary outcomes, we investigated differences in postoperative lactate dehydrogenase and bilirubin levels. Postoperative free hemoglobin levels were not significantly different between the groups. However, there were statistically significant differences between the treatment and control groups in the median levels of haptoglobin (58.4 vs. 17.9 mg/dL, respectively; P
