Modified Ultrafiltration After Congenital Heart Surgery: A Veno–Venous Method Using a Dual-Lumen Hemodialysis Catheter

open access: yes, 2023
Perfusion practice surveys on modified ultrafiltration show most clinicians reporting the use of arterial to venous cannulation. With an arterial–venous (A–V) approach, the patient’s blood is accessed in a retrograde direction from the cardiopulmonary ...

Effect of hydrophilic / hydrophobic fractions of Natural Organic Matter on irreversible fouling of membranes [PDF]

open access: yes, 2009
Natural organic matter (NOM) has been identified as a major factor affecting membrane processes performances, but its impact is difficult to quantify from global parameters such as organic carbon content.
