Preoperative assessment of a 55-year-old male patient
going for coronary angiography shows an estimated
glomerular filtration rate of 33 mL/min per 1.73 m2 and
poorly controlled diabetes. He is currently on no nephrotoxic
medications, and the nephrologist assures you that
he does not currently have acute renal failure. The case is
due to begin in 4 h, and you would like to prevent contrast
nephropathy. Which agent will definitely reduce the
risk of contrast nephropathy?
A. Dopamine
B. Fenoldopam
C. Indomethacin
D. N-acetylcysteine
E. Sodium bicarbonate
