WebJan 21, 2024 · However, as diffusive and convective transports are affecting each other, the total clearance by the combination of both techniques is not as high as the sum of the clearances of each single technique alone; diffusion lowers a solute’s concentration in the blood and, thereby, the potential removal capacity via convective transport. WebFeb 22, 2024 · Hemodiafiltration (HDF) is a form of kidney replacement therapy (KRT) that utilizes convective in combination with diffusive clearance. Compared with conventional hemodialysis, HDF removes more middle-molecular-weight solutes. WebMar 30, 2024 · Ricci Z, Ronco C, Bachetoni A, D'amico G, Rossi S, Alessandri E, Rocco M, Pietropaoli P.
