Renal replacement therapy in critical ill patients

Acute kidney injury (AKI), especially when caused or accompanied by sepsis, is associated with prolonged hospitalization, progression of chronic kidney disease (CKD), financial burden on the health care system, and increases mortality in various entities. Extended renal replacement therapy (CRRT) is the predominant form of renal replacement therapy (RRT) in intensive care units (ICU) by providing hemodynamic stability in critically ill patients, more precise control of fluid balance, correction of acid-base imbalances, electrolyte disorders and achieving a stable level of osmolarity correction, including in multimorbid patients. This article examines the various aspects of CRRT in critically ill patients with severe AKI with high comorbidity, as well as in patients with sepsis and multiple organ failure. An analytical evaluation of the choice of CRRT over intermittent/intermittent hemodialysis (IHD) in selected clinical settings is being conducted. Filter/dialyzer life is assessed, including assessment of filtration fraction, use of anticoagulation options including regional citrate anticoagulation (RCA), dose of CRRT prescribed and delivered, vascular access management, general criteria, timing of initiation and cessation of CRRT, and initiation of renal replacement therapy for nonrenal indications. with AKI and/or sepsis.
