Current role of sodium bicarbonate–based preprocedural hydration for the prevention of contrast-induced acute kidney injury: A meta-analysis

Abstract
The optimal hydration strategy for prevention of contrast-induced acute kidney injury (AKI) remains unknown. The purpose of this meta-analysis is to compare the effectiveness of normal saline (NS) versus sodium bicarbonate hydration (NaHCO3) for prevention of contrast-induced AKI.
