Hemofiltration, also haemofiltration, is a renal replacement therapy which is used in the intensive care setting. It is usually used to treat acute kidney injury (AKI), but may be of benefit in multiple organ dysfunction syndrome or sepsis. [1]

Similar to hemodialysis (HD), hemofiltration (HF) is a therapy designed to improve clearance for patients experiencing renal dysfunction. Hemofiltration is achieved by convective clearance, in which solutes are transported across a semipermeable membrane, along with movement of solvent (ultrafiltration) that occurs in response to a positive ...

The optimal choice of modality for acute renal replacement therapy is unclear at present. Diffusive therapy (hemodialysis) removes small solutes mainly, whereas convective therapies (hemofiltration and hemodiafiltration) may also eliminate …

In continuous hemofiltration, water and solutes filter from the blood by convection through a permeable membrane; the filtrate is discarded, and the patient must receive infusions of physiologically balanced water and electrolytes.

Divided into three parts, the book provides a swift but adequate and comprehensive introduction into the principles and techniques, devices, and practical aspects of haemofiltration. The first part explains the principles of blood purification and introduces the reader to …

Hemofiltration is a method whereby the removal of a compound occurs primarily by convective solute transport, rather than diffusion. It is performed using highly permeable membranes, with replenishment of the fluid or plasma water removed during treatment.

2018年4月9日 · HEMOFILTRATION (HF) In comparison to diffusion-based HD, HF relies on convection through a larger pore hemofilter. The key difference is the absence of dialysate. Instead, pressure is applied across this hemofilter, and solutes are pushed through the membrane along with plasma water.

1997年5月1日 · Hemofiltration does not cure acute renal failure, but it is a safe and efficient way of replacing renal function while the kidneys recover from disease or injury.

Our finding of a 33% shorter time to filter failure with hemofiltration, combined with its higher fluid requirements to achieve similar small molecule clearance, implies that hemofiltration may consume more resources than hemodialysis.

This extensive review describes the settings for continuous arteriovenous hemofiltration (CAVH) and attempts to compare it to traditional dialysis therapies for acute renal failure.
