Purpose of review: Since the adoption of the classification of acute kidney injury (AKI) through changes in serum creatinine and/or urine output, much data have accumulated as to the associated risks in terms of morbidity and mortality after the development of AKI. However, until recently, a nihilistic approach persisted which implied that little could be done to alter the clinical course of a patient with AKI even where early identification was achieved. This view is reinforced by the opinion that given the broad cause underlying the syndrome of AKI, a 'one size fits all' approach is unlikely to be successful.
Recent findings: Recent evidence suggests that the management of AKI may be improved somewhat by simple measures, such as the use of care bundles particularly in the intensive care setting. Moreover, there are other interventions using common treatments, which may prove to be of benefit as well as some early evidence that specific therapeutics may be on the horizon.
Summary: Although a syndrome of significantly differing causes, the application of standardized care bundles appears promising and this approach may be improved by the use of specific therapies, including recombinant alkaline phosphatase, the use of intravenous bicarbonate and remote ischaemic preconditioning may also ameliorate the effects of AKI.
