Preventing Contrast-Induced Acute Kidney Injury

Diagnostic radiographic imaging scans using intravascular iodinated contrast media can lead to various complications. The most salient of these is contrast-induced acute kidney injury (CI-AKI) or contrast-induced nephropathy, a potentially costly and serious patient safety concern. Prevention strategies are the cornerstone of evidence-based clinical management for patients receiving contrast agents. These include preprocedure screening, stratification of patients based on risk factors, and protective interventions, the most important of which is hydration both before and after the radiographic imaging scan. There is a gap, however, between best evidence and clinical practice in terms of exact hydration protocols. Nurses play an important role in nephropathy prevention and need to be familiar with CI-AKI as a potential complication of radiographic imaging scans. In order to ensure safe, high-quality care, nurses must be involved in efforts to prevent CI-AKI as well as interventions that minimize patients' risk of kidney injury.
