Hydration protocols to prevent the risk of AKI in high risk patients have been evaluated in various clinical publications. A single standard protocol has yet to be defined.
Clinical guidance has been outlined as:
• Intravenous(IV) hydration as preferable to oral hydration and that hydration four hours before and after exposure to dye is preferable to a bolus administration.8
Clinical studies have also outlined hydration protocols including:
• The POSEIDON trial’s use of Left Ventricle End Diastolic Pressure (LVEDP) guided hydration.
The volume of dye and risk of AKI has been well documented. Clinical studies have shown that minimization of dye is an important step to preventing AKI in patients undergoing heart imaging procedures (angiography).
