Scientific profile

 The Nephrological Intensive Care Medicine Working Group is concerned with the effects of current extracorporeal procedures in therapy in the intensive care unit, as well as the use of new innovative extracorporeal procedures and other therapeutic approaches for the treatment of septic patients.

Sepsis is a common condition associated with high mortality in internal medicine intensive care. Extracorporeal therapies are increasingly used not only in the treatment of septic complications such as acute renal failure requiring dialysis, but are also being investigated for immunomodulation and pathogen elimination as a therapy for sepsis itself. The aim is on the one hand to measure the extracorporeal elimination of toxins but also of important drugs such as antibiotics, and on the other hand to investigate the possible effectiveness of adsorption and apharesis techniques in the treatment of septic patients. Furthermore, we are concerned with the specific intensive care treatment of special nephrological patient groups (kidney transplant patients, patients with acute renal failure).
