Area of Science:

  • Biomedical Engineering
  • Nephrology
  • Immunology

Background:

  • Hemoperfusion (HP) has evolved from general toxin removal to specialized applications.
  • The development of specific and selective sorbents is crucial for targeted therapeutic interventions.

Purpose of the Study:

  • To review the state-of-the-art in hemoperfusion, focusing on selective sorbent development.
  • To explore HP applications in immunology, critical care, and uremia.
  • To present experimental studies using coated anion exchange resins for various medical conditions.

Main Methods:

  • Review of existing literature on hemoperfusion and sorbent technology.
  • Experimental application of coated anion exchange resins in treating acute respiratory insufficiency, metabolic alkalosis, and managing antiblastic agents.
