Fluid resuscitation is not only used to prevent acute kidney injury (AKI) but fluid management is also a cornerstone of treatment for patients with established AKI and renal failure. Ultrafiltration removes volume initially from the intravascular compartment inducing a relative degree of hypovolemia. Normal reflex mechanisms attempt to sustain blood pressure constant despite marked changes in blood volume and cardiac output. Thus, compensated shock with a normal blood pressure is a major cause of AKI or exacerbations of AKI during ultrafiltration. ⋯ Prospective clinical trials using functional hemodynamic markers in the diagnosis and management of AKI and volume status during ultrafiltration need to be performed. More traditional measure of preload be abandoned as marked of volume responsiveness though still useful to assess overall volume status.

To describe current knowledge on the epidemiology of cardiac surgery-associated acute kidney injury (CSA-AKI) and to formulate recommendations for clinical practice and a research agenda. ⋯ Existing data on the epidemiology of CSA-AKI are difficult to compare due to variations in definition and patient cohort. A modified Delphi analysis resulted in a series of recommendations for future research on CSA-AKI.

The Acute Dialysis Quality Initiative (ADQI) is an ongoing process that seeks to produce evidence-based recommendations for the prevention and management of acute kidney injury (AKI) and on different issues concerning acute dialysis. Our methods involve a combination of both expert panel and evidence appraisal, and this approach was chosen to achieve the best of both options. This approach has led to important practice guidelines with wide acceptance and adoption into clinical practice. We further recognize that additional research will be needed and have proposed specific studies that will help move this field forward.
