I. Definition• Traditional Definition of CI-AKI
An increase in SCr by more than 25% or 44 μmol/L in the 3 days following intravascular administration of contrast medium (CM) in the absence of an alternative etiology.
• Other Definition of CI-AKIAn increase in CysC by more than 10% in the
24h following intravascular administration of contrast medium (CM).
![Page 8: 2012 Updates on Management of Contrast Induced AKI —— Guidelines & New Evidences Prof. Ben He MD PhD FACC Shanghai Renji Hospital Shanghai Jiaotong University](https://reader036.vdocument.in/reader036/viewer/2022062517/56649ed05503460f94bde599/html5/thumbnails/8.jpg)
• New Definition:
I. Definition
Stage 1: SCr increased 1.5–1.9 times baseline SCr increase >0.3mg/dl (26.5 μmol/l) Urinary output < 0.5ml/kg/h during a 6 hour blockStage 2: SCr increase 2.0–2.9 times baseline Urinary output <0.5ml/kg/h during two 6 hour blocksStage 3: SCr increase >3 times baseline SCr increases to >4.0mg/dl (353 μmol/l) Initiation of renal replacement therapy Urinary output <0.3ml/kg/h during more than 24 hours Anuria for more than 12 hours

New Simple Algorithm: To stratify the risk of CI-AKI
Maximum Allowable Contrast dose (MACD) was defined as 5*body weight/SCr
Increases the positive predictive value of the Mehran risk score (40.7% vs 8.8%)
with the same sensitivity (90.7% vs 83.3%)

III. Pharmacological Prevention
• Volume expansion with either isotonic NS or SB
(1A)
• Oral route for hydration, on the premise that
adequate intake of fluid and salt are assured (2C)
• Oral N-acetyl cysteine (NAC) only in appropriate
fluid and salt loading (2D). Not using oral NAC as the
only method (1D)
• Do not suggest using theophylline (2C)
• Do not recommend using fenoldopam (1B) 2011 PCI guideline
![Page 21: 2012 Updates on Management of Contrast Induced AKI —— Guidelines & New Evidences Prof. Ben He MD PhD FACC Shanghai Renji Hospital Shanghai Jiaotong University](https://reader036.vdocument.in/reader036/viewer/2022062517/56649ed05503460f94bde599/html5/thumbnails/21.jpg)
Optimal Hydration Protocol:
(A) NS 1 mL/kg/h for at least 12 h prior and after the procedure
(B) SB 3 mL/kg for 1 h before and 1 mL/kg/h for 6 h after the
procedure
(C) SB 3 mL/kg over 20 min before the procedure plus sodium
bicarbonate
orally (500 mg per 10 kg).

24 h sodium chloride 0.9% is superior to sodium bicarbonate.
A short-term regimen with sodium bicarbonate is non-inferior to a 7 h regimen.

Perioperative high-dose statin load to reduce perioperative myocardial infarction has been recognized;
Prevention of CIN may be derived from the pleiotropic effects of statins.

Protocol: IPC was accomplished by performing 4 cycles of alternating 5-minute inflation and 5-minute deflation of a standard upper-arm blood pressure cuff to the individual’s systolic blood pressure plus 50 mm Hg to induce transient and repetitive arm ischemia and reperfusion.
