Randomized Controlled Trial Comparative StudyRenal Insufficiency Following Radiocontrast Exposure Trial (REINFORCE): a randomized comparison of sodium bicarbonate versus sodium chloride hydration for the prevention of contrast-induced nephropathy.
For the prevention of contrast-induced nephropathy (CIN) after coronary angiography, hydration by 0.9% sodium chloride solution and N-acetylcysteine is currently recommended. However, it is unclear whether volume supplementation with sodium bicarbonate is better than with sodium chloride when used in conjunction with nonionic, low-osmolar iopamidol. The aim of this study was to analyze and compare the effects of sodium bicarbonate and sodium chloride on renal function in 145 patients exposed to nonionic iso-osmolar contrast medium iodixanol in a randomized study. ⋯ Renal Insufficiency Following Radiocontrast Exposure demonstrates a homogeneously low rate of CIN after exposure to nonionic, iso-osmolar iodixanol regardless of the use of either bicarbonate sodium or sodium chloride solution for volume supplementation. Low-toxicity contrast media and any hydration may offset potential antioxidant effects of sodium bicarbonate.
