Answer

In patients undergoing imaging studies with contrast, prophylactic administration of IV fluid has been shown to decrease the incidence of contrast nephropathy. Although controversy exists regarding the ideal fluid, normal saline and isotonic NaHCO3 have proved to be effective. A normal saline solution of 1 mL/kg/h administered 12 hours before the procedure and then 12 hours after the procedure is recommended for most patients.
