Patients at risk for contrast-induced nephropathy
Establishing the Current Renal Status of the At-Risk Patient
- Measure serum creatinine within 7 days of the contrast-enhanced examination in non-emergency
situations for the following conditions:
- Intra-arterial administration
- Age >70 years
- Diabetes mellitus
- Hypertension
- History of renal disease or recent renal surgery
- Recent major surgery or coronary artery bypass graft surgery
- Recent (within 7 days) exposure to radiographic contrast agents
