Brief summary
Objective：The purpose of the study is to confirm that extending the duration of hemoadsorption (HA) and increasing blood flow during the HA+hemodialysis (HD) treatment process is safe and feasible, and to verify that extending the HP treatment duration can further increase the clearance of protein-bound uremic toxins. Methods: The study employs a multicenter, prospective, cohort design with a self-controlled before-and-after comparison. The duration of HA+HD treatment for maintenance hemodialysis (MHD) patients is extended to 4 hours, and the extracorporeal blood flow rate is increased to over 250-350 ml/min. The safety of the treatment is assessed by evaluating the safety of the procedure; the levels of relevant toxins in the patients' blood are measured before and after treatment, and the clearance rate of uremic toxins after a single treatment is calculated and compared with the self-controlled before-and-after data to determine whether the modified protocol can remove more uremic toxins.
