Modified ultrafiltration during cardiopulmonary bypass and postoperative course of pediatric cardiac surgery [PDF]

Research in Cardiovascular Medicine, 2014
Context: The use of cardiopulmonary bypass (CPB) provokes the inflammatory responses associated with ischemic/reperfusion injury, hemodilution and other agents. Exposure of blood cells to the bypass circuit surface starts a systemic inflammatory reaction

In vitro evaluation of critical ultrafiltration fluxes and transmembrane pressure in a high flux dialyzer [PDF]

Scientific Reports
In patients treated with haemodiafiltration, high convection volumes are considered beneficial. However it leads to pressure instability and membrane fouling.

Zn²⁺-Mediated Co-Deposition of Dopamine/Tannic Acid/ZIF-8 on PVDF Hollow Fiber Membranes for Enhanced Antifouling Performance and Protein Separation [PDF]

Membranes
The inherent hydrophobicity of poly(vinylidene fluoride) (PVDF) ultrafiltration membranes leads to severe membrane fouling when processing proteinaceous solutions and organic contaminants, significantly limiting their practical applications.
