Albumin Administration for Paracentesis
Albumin infusion should be administered when removing more than 5 liters of ascitic fluid during paracentesis, at a recommended dose of 6-8 g of albumin per liter of ascites removed to prevent post-paracentesis circulatory dysfunction. 1, 2
Volume Thresholds for Albumin Administration
Large-volume paracentesis (LVP) is defined as removal of >5 liters of ascitic fluid. When this threshold is reached, albumin replacement becomes necessary:
- <5 liters removed: Albumin infusion generally not required as paracentesis of smaller volumes is not associated with significant hemodynamic changes 1
- >5 liters removed: Albumin infusion is recommended to prevent post-paracentesis circulatory dysfunction (PPCD) 1, 2
- >8 liters removed: Risk of PPCD increases significantly; careful monitoring and appropriate albumin replacement is critical 1
Dosing of Albumin
The American Association for the Study of Liver Diseases (AASLD) recommends:
- 6-8 g of albumin per liter of ascites removed 1, 2
- For example:
- After 5 liters: approximately 40 g of albumin
- After 8 liters: approximately 64 g of albumin
Clinical Considerations
Safety and Efficacy
- Total paracentesis in a single session (removing up to 10-11 liters) can be safely performed when appropriate albumin replacement is provided 3
- Implementation of standardized order sets for albumin dosing has been shown to optimize albumin utilization without compromising patient outcomes 4
Risks of Inadequate Albumin Replacement
Failure to administer adequate albumin during LVP can lead to:
- Post-paracentesis circulatory dysfunction (PPCD)
- Renal impairment including hepatorenal syndrome
- Dilutional hyponatremia
- Hepatic encephalopathy
- Increased mortality 1, 2
Procedure Recommendations
- Paracentesis should be performed under strict sterile conditions, preferably with ultrasound guidance 2
- Complete drainage to dryness in a single session is generally recommended rather than repeated small-volume paracentesis 2
- Diuretics should be reintroduced within 1-2 days after paracentesis to manage the underlying condition 2
Common Pitfalls to Avoid
- Underdosing albumin: Providing insufficient albumin replacement increases risk of PPCD and associated complications
- Removing >8 liters without proper monitoring: Higher volumes removed in one session require careful monitoring and appropriate albumin replacement
- Repeated small-volume paracentesis: This approach offers no additional benefits and may increase procedure-related complications 2
- Leaving drains in overnight: Increases infection risk and should be avoided 2
- Failure to monitor for complications: Patients should be monitored for hyponatremia, renal impairment, and hypotension following the procedure 4
By following these evidence-based guidelines for albumin administration during paracentesis, clinicians can effectively manage ascites while minimizing the risk of complications that could increase morbidity and mortality in patients with cirrhosis.
