In 2007, a national guideline was issued in the Netherlands to prevent contrast-induced nephropathy. This guideline recommended preventive hydration with 0.9% NaCl in patients with reduced estimated glomerular filtration rate (eGFR 30-69 ml/min/1.73 m2) prior to administration of contrast. The recent AMACING study compared hydration versus no hydration, and found that hydration did not prevent contrast-induced nephropathy but did lead to complications and higher costs. The latest 2017 guideline recommends hydration only for patients with eGFR < 30 ml/min/1.73 m2. Although this is an improvement, an even more recent study, PRESERVE, showed no differences in the incidence of contrast-induced nephropathy between sodium chloride, sodium bicarbonate, acetylcysteine, or placebo - even in patients with lower eGFRs (15-60 ml/min/1.73 m2) undergoing elective angiography. This raises the question whether preventive measures are only effective in patients with the highest risk, i.e. hospitalized patients with multiple risk factors undergoing emergency procedures.
