SUMMARY
1. Sedation: risk of aspiration & respiratory depression; the patient should have no clear liquids for 2 hrs and no solids for 6 hrs before the procedure.
2. Contrast agents: using the lowest possible dose of the nonionic form of contrast helps to minimize the risk of developing renal toxicity; keeping the iodine dose < 3g minimizes toxicity;
3. Gadolinium: can substitute iodinated contrast and has less toxicity.
4. Metformin: Metformin can increase the risk of renal toxicity and precipitate severe lactic acidosis in diabetic patients, withhold it after the use of iodinated contrast.
5. Nephrotoxic meds: combining contrast with nephrotoxic meds increases risk of renal toxicity.
