hemofiltration /he·mo·fil·tra·tion/ (-fil-tra´shun) removal of waste products from blood by passing it through extracorporeal filters.
hemofiltration
hemofiltration [he″mo-fil-tra´shun]
he·mo·fil·tra·tion (h  m -f l-tr  sh n)n. A process similar to hemodialysis, by which blood is dialyzed using ultrafiltration and simultaneous reinfusion of physiologic saline solution. |
hemofiltration
[-filtrā′shən]
a type of hemodialysis in which there is convective transport of the solute through ultrafiltration across the membrane. It is reported to be more effective than diffusion in removing higher-molecular weight solutes from the blood, particularly in the treatment of uremia. Also spelled haemofiltration.
hemofiltration [he″mo-fil-tra´shun]
the removal of waste products from the blood by using large amounts of ultrafiltration with reinfusion of sterile replacement fluid. See also hemoperfusion.
continuous arteriovenous hemofiltration a form of continuous renal replacement therapy consisting of hemofiltration with arteriovenous access using small-volume, low-resistance filters powered by the patient's arterial pressure, without need for a mechanical pump; used as an alternative to conventional hemodialysis in patients with acute renal failure.
continuous venovenous hemofiltration a process similar to continuous arteriovenous hemofiltration but using venovenous access and a mechanical pump.
hemofiltration
the removal of waste products from the blood by passing the blood through extracorporeal filters.
