All you need to know about Post Contrast Acute Kidney Injury (AKI)
These two articles explain in detail AKI and provide recommendations for everyday practice. A “must read” for every radiologist and radiographer, who should adopt these recommendations, and also promote their use in cooperation with referring clinicians.
- PC-AKI is the preferred term for renal function deterioration after contrast medium.
- PC-AKI has many possible causes.
- The risk of AKI caused by intravascular contrast medium has been overstated.
- Important patient risk factors for PC-AKI are CKD and dehydration.
- In CKD, hydration reduces the PC-AKI risk.
- Intravenous normal saline and intravenous sodium bicarbonate provide equally effective prophylaxis.
- No drugs have been consistently shown to reduce the risk of PC-AKI.
- Stop metformin from the time of contrast medium administration if eGFR < 30 ml/min/1.73 m 2.
- Dialysis schedules need not change when intravascular contrast medium is given.
