A patient is to undergo angiography for unstable angina. His routine evaluation revealed his serum creatinine to be elevated. All of the following can be used to prevent contrast nephropathy, EXCEPT:
Strategies for the Prevention of Contrast-Induced Nephropathy: Strategies that do not work: Mannitol Furosemide Dopamine Atrial natriuretic factor Fenoldopam Hemodialysis Strategies that may work: Calcium channel blockers Theophylline N-Acetylcysteine Hemofiltration Sodium bicarbonate Ascorbic acid Iso-osmolar contrast media Current recommended strategies: Employ non iodinated contrast studies Avoid nonsteroidal anti-inflammatory agents Space between contrast administrations Minimize contrast volume Hydration Low osmolar contrast media Ref: Brunelli S., Rudnick M.R.
