Diagram of hemodiafiltration with regeneration of the ultrafiltrate by adsorption in resin. 1: High permeability filter (Convection). 2: Resin cartridge (Adsorption). 3: Low permeability filter (Diffusion). Protocol of samples extraction: The blood samples were obtained from the arterial port of the central venous catheter before (pre) (a) and immediately after (post) (b) the completion of the dialysis procedure (a total of 2 samples). Ultrafiltrate, pre (c) and post (d) resin, samples were taken at 5 min after starting the session (2 samples) and 5 min before the end of the session (2 samples). A total of six samples were collected during the procedure: 2 arterial blood samples and 4 samples of ultrafiltrate.
