Renal replacement therapy in the end-stage renal disease patient with critical illness

Abstract

Dialysis patients account for 1-9% of all intensive care unit (ICU) admissions. As a result of the increasing prevalence of patients with end-stage renal disease (ESRD) and the changing demographics of this population, the number of dialysis patients requiring hospitalization and ICU support is expected to increase. Critically ill ESRD patients have more comorbidity and higher severity of illness than the general population resulting in higher ICU and in-hospital mortality rates. ESRD patients have been excluded from trials evaluating renal replacement therapy in the ICU, therefore little information is available about the optimal management of renal replacement therapy for dialysis patients in this setting. This review focuses on the epidemiology of chronic dialysis patients admitted to the ICU and discusses an approach to providing renal replacement therapy for critically ill patients with ESRD.
