ReviewThe meaning of acute kidney injury and its relevance to intensive care and anaesthesia.
Acute kidney injury (AKI) is the new consensus term for acute renal failure. The term describes a continuum of kidney injury, a common condition in the critically ill and after major surgery, which is associated with increased mortality. The incidence of AKI in intensive care unit patients in Australia is >30% and sepsis is a major contributory factor. ⋯ In this review, we explore the limitations of animal and human models of AKI and the implications of recent research on our current understanding of the pathophysiology of AKI. In addition, we describe conventional and novel diagnostic methods and therapies, and explore the clinical implications of the effect of fluid administration and perioperative management. Finally, we identify priorities for clinical investigations and future directions in AKI research.
