Contrast nephropathy presents as non-oliguric acute renal failure 1 to 5 days post procedure.
Risk of contrast nephropathy can be reduced by:
- good hydration/normal saline
- oral n.acetyl cysteine
Risk of contrast nephropathy is increased by:
- increased amount of contrast
- hypovolaemia
- myeloma
- increasing age
- diabetes
- raised calcium
- chronic renal failure
Remember that metformin must be withheld before and for 48 hrs post IV contrast due to risk of lactic acidosis.
Now to end on a high with a battle with minimal change disease...
