Paracentesis Guidelines

Indications and Contraindications

Diagnostic paracentesis should be performed in all patients with new-onset Grade 2 or 3 ascites, all hospitalized patients with worsening ascites, and any cirrhotic patient with complications including fever, abdominal pain, gastrointestinal bleeding, hepatic encephalopathy, hypotension, or renal insufficiency, as recommended by the American Association for the Study of Liver Diseases 1
Therapeutic paracentesis is first-line treatment for patients with large or refractory ascites causing symptomatic relief, according to the European Association for the Study of the Liver 2
The only absolute contraindication for paracentesis is clinically evident hyperfibrinolysis or disseminated intravascular coagulation, as stated by the American Association for the Study of Liver Diseases 1

The left lower quadrant is the preferred location for paracentesis, 2 finger breadths cephalad and 2 finger breadths medial to the anterior superior iliac spine, as recommended by the American Association for the Study of Liver Diseases 6
Use "Z-track" technique and a cannula with multiple side perforations to prevent bowel wall blockage, as suggested by the European Association for the Study of the Liver 2
Perform paracentesis under strict sterile conditions, as recommended by the European Association for the Study of the Liver 2

All ascitic fluid should be drained to dryness in a single session as rapidly as possible over 1-4 hours, as recommended by the European Association for the Study of the Liver 2
No upper limit is specified in current guidelines when appropriate albumin replacement is given, according to the European Association for the Study of the Liver 5

For paracentesis >5 liters, albumin replacement is mandatory at 8 g per liter of ascites removed to prevent post-paracentesis circulatory dysfunction (PICD), as recommended by the European Association for the Study of the Liver 2
Albumin reduces PICD by 61%, mortality by 36%, and hyponatremia by 42% compared to alternative plasma expanders, as reported by the American Association for the Study of Liver Diseases 8

Severe hemorrhage occurs in 0.2-2.7% of procedures, with a death rate of 0.02% (1 in 5,000 procedures), as reported by the American Association for the Study of Liver Diseases 1
Most bleeding occurs within 6-24 hours but can be delayed up to 1 week, and bleeding sources include superficial epigastric vein, inferior epigastric artery, mesenteric varices, and paraumbilical vein, as described by the American Association for the Study of Liver Diseases 1
