Fluid Management for Heart Catheterization Patients with CKD

Pre-Procedure Fluid Management

The European Society of Cardiology recommends that all CKD patients undergoing cardiac catheterization should receive preventive hydration with isotonic saline, especially those with GFR < 40 mL/min/1.73 m² 1
For patients with moderate-to-severe CKD, pre-hydration with isotonic saline is a Class I, Level A recommendation, according to the European Heart Journal 2
If expected contrast volume is >100 mL, pre- and post-hydration with isotonic saline should be considered (Class IIa, C), as suggested by the European Heart Journal 3, 4
Consider delaying any cardiac surgery after coronary angiography until the effect of contrast media on renal function has subsided, as recommended by the European Heart Journal 1

For patients with moderate CKD, the European Heart Journal recommends standard hydration with isotonic saline before and after the procedure 2
For patients with severe CKD, a fluid replacement rate of 1000 mL/h without negative loss and saline hydration continued for 24 hours after the procedure is recommended (Class IIb, B), according to the European Heart Journal 2
As an alternative to standard pre- and post-hydration, tailored hydration regimens may be considered (Class IIb, B), as suggested by the European Heart Journal 4
For high-risk patients, furosemide with matched hydration may be considered, starting with 250 mL intravenous bolus of normal saline over 30 min, followed by furosemide (0.25–0.5 mg/kg), as recommended by the European Heart Journal 2

The European Heart Journal recommends using low-osmolar or iso-osmolar contrast media (Class I, A) 2, 3
Iso-osmolar contrast media should be preferred over low-osmolar media (Class IIa, A), according to the European Heart Journal 2
Minimize contrast volume (Class IIa, B): Keep total volume <350 mL or <4 mL/kg or total contrast volume/GFR <3.4, as recommended by the European Heart Journal 2, 6
Consider short-term, high-dose statin therapy before the procedure (Rosuvastatin 40/20 mg, atorvastatin 80 mg, or simvastatin 80 mg) (Class IIa, A), as suggested by the European Heart Journal 2

N-Acetylcysteine administration instead of standard hydration is not indicated (Class III, A), according to the European Heart Journal 2
Infusion of sodium bicarbonate 0.84% instead of standard hydration is not indicated (Class III, A), as recommended by the European Heart Journal 2
Hold nephrotoxic medications before procedure, including NSAIDs, metformin, and aminoglycosides, as suggested by the European Heart Journal and other guidelines 5

Monitor for signs of acute kidney injury, typically defined as an increase in serum creatinine of ≥0.5 mg/dL or ≥25-50% from baseline within 2-5 days following contrast administration, as recommended by the European Heart Journal and other guidelines 5
Continue hydration for at least 24 hours after the procedure, especially in severe CKD, according to the European Heart Journal 2
Prophylactic renal replacement therapy is not recommended as a preventive measure (Class III, B), as suggested by the European Heart Journal 2

For patients with multivessel coronary artery disease and CKD, CABG should be considered over PCI if surgical risk is acceptable and life expectancy is >1 year (Class IIa, B), according to the European Heart Journal 1, 3
PCI should be considered over CABG in patients with multivessel CAD whose surgical risk profile is high or life expectancy is less than 1 year (Class IIa, B), as recommended by the European Heart Journal 1
Patients with advanced kidney disease (eGFR <15 mL/min/1.73m²) or on dialysis may not benefit from invasive strategies as much as those with mild-moderate CKD, as suggested by Circulation 7
