Overview

Cardiopulmonary bypass (CPB) allowed the correction of several congenital heart diseases such as intracardiac malformations, but it is well known that this is not a harmless procedure because it can lead to a systemic inflammatory response syndrome (SIRS), with activation of complement, cytokines, coagulation, and fibrinolysis pathways.

Due to economic causes, hemofilters became less available in low-resource countries, which forced perfusionists to use hemodialyzers instead during CPB. Preliminary data showed the potential safety of using hemodialyzers instead of hemofilters in Zero-balanced ultrafiltration.

The Objectives of the study This study aims to compare impact of hemofilters and hemodialyzers on cytokine removal during cardiopulmonary bypass in pediatric cardiac surgery.
