Introduction

Question 1

Estimated creatinine clearance rate?

Answer 1

Use Cockcroft-Gault formula:
Cr Clearance = (140-age) * Weight / ( 72 * Cr)
Women - Multiply with 0.85
Good when CCT > 60
For low CCT better use MORD formula

Question 2

Contrast Nephrotoxicity - Risk Factors?

Answer 2

1. Pre existing renal impirament
2. Diabetes
3. Age > 75
4. Fluid Depletion
   MM
5. Nephrotoxic Drugs
6. Uricosuria
7. Ionic Contrast Media

Question 3

Answer 3

No Treatments

Pts should be given Mucomyst + Normal Saline as preperation

Question 4

Contrast Nephrotoxicity - Timing?

Answer 4

Up to 72 hours after test

Question 5

Proteinuria limits?

Answer 5

0-30 mg / 24 hours - NormoAlbuminuria
30-300 mg / 24 hours - MicroAlbuminuria
Above 300 mg / 24 hours - MacroAlbuminuria
