Abstrakt: Biocompatible cardiopulmonary bypass (CPB) circuits aim to reduce contact activation and its physiological consequences. We investigated the hypothesis that use of Surface Modifying Additive (SMA)-treated circuits (Sorin Group Ltd) compared with non-SMA circuits would be associated with preservation of blood pressure during CPB and modulation of perioperative subclinical renal function (urinary alpha-1-microglobulin (alpha-1-m)) and plasma and urinary cytokine changes. In a study of low-risk CABG patients (n=40), randomized to SMA (n=20) versus non-SMA circuits (n=20), we found better preserved blood pressure at CPB initiation in SMA patients (p <0.05), particularly in ACE-inhibited SMA patients (n =11) versus ACE-inhibited non-SMA patients (n =10) (p <0.05). Plasma anti-inflammatory IL-10, as well as urinary alpha-1-m, were elevated 48 hours postoperatively (p <0.05). SMA patients also had lower blood loss (p <0.05). SMA circuits have some clinical benefit, especially in ACE-inhibited patients. [ABSTRACT FROM AUTHOR]
