Hemofiltration and hemodialysis are two different treatment modalities, targeting different conditions, then the treatment effect is also different, there is a difference.
1. Hemofiltration: that is, blood filtration, through convection and transmembrane pressure to remove the solution and part of the solute, mainly for water and large, medium and small molecules of solute, has a better effect, is more suitable for the cardiovascular status of the unstable intolerance of hemodialysis patients, as well as need to remove medium and large molecules of toxins in the patient, you can choose to hemofiltration has a better effect.
2. Hemodialysis: that is, hemodialysis, hemodialysis is the use of hemodialysis machine to purify the blood, through the diffusion effect to remove solutes, mainly for the removal of water, small molecules of solutes, have better results. It is more effective in removing creatinine, urea and other small molecule solutes, and is more suitable for chronic renal failure, acute drug intoxication and so on.
The above two kinds of renal replacement therapy can be used in the treatment of kidney disease, but the role is different can be used alternatively, the specific treatment, need to be considered by the doctor after comprehensive consideration, choose the appropriate treatment.
