Abstract
Acute kidney injury (AKI) requiring treatment with renal replacement therapies is common in the critically ill, during which periods of hemodynamic instability, often manifest as a decrease in blood pressure, are frequently observed. The reported incidence of such episodes of hypotension varies considerably due, in part, to a lack of consensus as to what defines hemodynamic instability under such circumstances, as well as other factors, including treatment modality employed, and characteristics of the patient group under scrutiny. Historically, much of the limited understanding as to the mechanisms behind these observations comes from the chronic dialysis population where excessive volume removal may underpin falls in blood pressure. However, this may well be an oversimplification of the pathophysiology behind such hypotension observed on the intensive care unit, where excessive ultrafiltration for example, may not be the cause of the observed hemodynamic disequilibrium. Here we describe our current understanding regarding hemodynamic instability associated with renal replacement therapy as well as the epidemiology of this phenomenon.
