    • In the absence of hemorrhagic shock, use of isotonic crystalloids rather than colloids for intravascular volume expansion.

    • Do not use diuretics to prevent or treat AKI except in the management of volume overload.

    • Do not use low-dose dopamine in either the prevention or treatment of AKI.

    • Use vasopressors in addition to fluids for management of vasomotor shock with or at risk for AKI.
