Harm of forced diuresis to prevent CIN

In this trial of 92 patients with creatinine >1.7 mg/dl undergoing cardiac catheterization, they were randomized to saline hydration, or euvolemic forced diuresis (with saline, mannitol, and furosemide). The forced diuresis group had a significantly higher rate of CIN (50% vs 28%). The same study did a meta-analysis (including 2 other studies with a total of 251 patients) and found the relative risk of harm of forced diuresis (compared to saline hydration) was 2.15 (CI 1.37 to 3.37). Forced diuresis to prevent CIN is harmful (abstract).
