Contrast-induced nephropathy is the third most common cause of hospital-acquired renal failure, after decreased renal perfusion and nephrotoxic medications. Identification of patients at risk and implementation of preventive strategies can decrease the incidence of this nephropathy. Prevention strategies focus on counteracting vasoconstriction, enhancing blood flow through the nephron, and providing protection against injury by oxygen free radicals. Knowledge of the adverse effects associated with infusion of contrast media, identification of patients at risk for contrast-induced nephropathy, and application of evidence-based prevention strategies allow nurses to assist in the prevention of contrast-induced nephropathy.
