Contrast-associated acute kidney injury.

Acc © 20 For Discuss the current evidence for the association between contrast administration and development of AKI. Identify patients at high risk of developing CAAKI. Implement preventative measures to reduce the risk of CA-AKI. lower osmolality contrast agents reduce the risk of CA-AKI. Acute kidney injury (AKI) is common, occurring in more than 15% of patients admitted to hospital as an emergency. AKI often indicates severe systemic dysfunction and can lead to chronic kidney disease (CKD) and increased mortality. Early proactive recognition, prevention and activemanagement can reduce the incidence of AKI. Contrast-associated AKI (CA-AKI) is typified by a deterioration of renal function in the days after intravascular injection of a contrast agent. Historically, the prevalence of CA-AKI was thought to be substantial, and considered to be a direct effect of iodinated contrast agents. Newer evidence questions the prevalence of CA-AKI and the significance of contrast in contributing towards AKI. In this review we describe the
