Answer

A study in 92 patients undergoing coronary angiography documented a significantly increased risk of contrast-induced nephropathy in patients who received forced euvolemic diuresis with saline, mannitol, and furosemide, compared with those who received saline hydration. [60] A systematic review and meta-analysis of mannitol administration for AKI prevention concluded that mannitol is in fact detrimental for contrast-induced nephropathy. [61]

However, studies of forced diuresis with matched controlled hydration have reported a decrease in the incidence of AKI. [62, 63, 64] These studies have used a device, the RenalGuard System (RenalGuard Solutions, Inc; Milford, MA) that matches saline infusion rates to the patient’s urine output by volume and time. The device is commercially available in Europe but is still under study in the United States. [65]
