A number of groups have developed methods using continuous ultrafiltration [ 45, 46].
In this paper, an approach for the optimal design and operation of a continuous ultrafiltration installation is presented.
Renal replacement therapy (RRT) in the form of isolated or continuous ultrafiltration, with or without a component of solute clearance (hemofiltration or hemodialysis), has been increasingly utilized as a therapeutic tool in this setting.
The advantages and disadvantages of batch and continuous ultrafiltration plants are discussed.
Peritoneal ultrafiltration (pUF) may allow chronic treatment of diuretic resistance by providing continuous ultrafiltration without the need of central venous access or hospital admission [ 5].
Slow continuous ultrafiltration was used in four patients (13.7%), hemodiafiltration (CVVHDF) modality in 13 (44.8%), hemodialysis (CVVHD) in 11 (37.9%).
We therefore allowed the use of isolated ultrafiltration on nondialysis days as required for volume management.
However, there are no strict recommendations regarding the preferential use of diuretics, ultrafiltration or in combination, as stated earlier.
In most patients, continuous veno-venous hemodiafiltration, including slow continuous ultrafiltration, was performed using the PRISMA (Gambro, Hechingen, Germany) platform.
Compared with extracorporeal modalities, pUF as an intracorporeal treatment offers device-specific advantages such as continuous ultrafiltration, fluid removal from the non-vascular space and avoidance of a compensatory increase of sympathetic activity.
