Variant Haemofiltration (Orthographic variant), HF (acronym)
Definition Hemofiltration refers to the use of a transmembrane hydrostatic pressure (THP) gradient to induce filtration of plasma water across the membrane of the hemofilter. The solute accompany their solvent (solvent drag) across the membrane resulting in the convective transport of small and medium-molecules (< 50000 Da).
Haemofiltration is an alternative form of renal replacement therapy where solute removal is activated only by convection, rather than diffusion as in haemodialysis
Hemofiltration has superior ´middle-molecules´ clearance but poor clearance of small molecules compared with diffusive hemodialysis
