Overview
Solute diffusion across a membrane is the basic principle for hemodialysis. Metabolic waste products move across a semipermeable membrane depending on their concentration gradient between plasma and dialysate. Concentration gradient, membrane surface area, the membrane thickness, and size of solute molecule are important factors determining rate of diffusion. Small molecules clear more efficiently than larger molecules. In-center hemodialysis and home hemodialysis are available for ESRD patients requiring renal replacement therapy; the choice of modality is based on patient condition, patient preference, and the availability of equipments.
