Albumin Replacement Guidelines After a 3L Paracentesis

For a 3-liter paracentesis, albumin replacement is generally not required as paracentesis volumes less than 5 liters are not typically associated with significant hemodynamic changes. 1, 2

General Guidelines for Albumin Replacement in Paracentesis

  • Albumin replacement is strongly recommended for large-volume paracentesis (LVP) of >5 liters at a dose of 6-8 g of albumin per liter of ascites removed 3, 1, 2
  • For paracentesis of <5 liters (including 3L), albumin replacement is generally not required as these smaller volume removals are not associated with significant hemodynamic changes 2
  • When albumin is administered, it should be infused after paracentesis is completed, not during the procedure, using 20% or 25% albumin solution 1

Special Considerations

  • For high-risk patients (those with acute-on-chronic liver failure or high risk of post-paracentesis acute kidney injury), consider albumin replacement at 8 g/L even for volumes <5 liters 1, 2
  • The primary concern with large-volume paracentesis is post-paracentesis circulatory dysfunction (PICD), which can lead to renal impairment, hyponatremia, and increased mortality 4, 5
  • Studies have shown that albumin is superior to alternative plasma expanders in preventing PICD, with a significant reduction in this complication (OR=0.39; 95% CI, 0.27-0.55) 5

Clinical Decision Algorithm

  1. For standard 3L paracentesis:

    • No albumin replacement needed for most patients 1, 2
  2. For high-risk patients undergoing 3L paracentesis:

    • Consider albumin replacement at 8 g/L (24g total for 3L) if patient has:
      • Acute-on-chronic liver failure
      • History of renal dysfunction
      • High risk of post-paracentesis acute kidney injury 1, 2
  3. For paracentesis >5L:

    • Administer 6-8 g albumin per liter of ascites removed 3, 1
    • Use 20% or 25% albumin solution 1
    • Infuse after paracentesis is completed 1

Different Clinical Scenario: Spontaneous Bacterial Peritonitis (SBP)

  • For patients with SBP, a different dosing regimen is recommended: 1.5 g albumin/kg within 6 hours of diagnosis, followed by 1 g/kg on day 3 3, 4
  • This regimen reduces the risk of renal dysfunction by 72% and mortality by 47% in patients with SBP 3

Common Pitfalls to Avoid

  • Don't routinely administer albumin for small-volume paracentesis (<5L) in low-risk patients, as this is not cost-effective and provides no proven clinical benefit 2, 4
  • Don't delay albumin administration when indicated for high-risk patients or large-volume paracentesis, as timely administration is important for preventing complications 1
  • Don't leave drainage catheters in place overnight, as this increases risk of infection and other complications 1
