Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Diagnostic Paracentesis
Required for all new-onset ascites
- Cell count + differential
- Albumin (calculate SAAG)
- Total protein
- Culture if infection suspected
- SAAG ≥1.1 = portal hypertension
03Decision Classify Ascites Grade
International Ascites Club classification
- Grade 1: Only detectable by ultrasound
- Grade 2: Moderate, symmetric distension
- Grade 3: Large/tense ascites
04Action Grade 1-2 (Uncomplicated)
Medical management first-line
- Sodium restriction: 2g/day (88 mmol)
- No fluid restriction unless Na <125
- Start spironolactone 100mg daily
- May add furosemide 40mg if needed
05Action Diuretic Titration
Goal: 0.5 kg/day weight loss (1 kg if edema)
- Maintain 100:40 ratio (spironolactone:furosemide)
- Increase every 3-5 days if inadequate response
- Max: spironolactone 400mg + furosemide 160mg
- Monitor K+, Cr, Na
06Decision Assess Response
After 2 weeks of therapy
07Action Diuretic-Responsive Ascites
Continue current regimen
- Maintain sodium restriction
- Titrate diuretics to minimum effective dose
- Monitor electrolytes, renal function
- SBP prophylaxis if indicated
08Outcome Ascites Controlled
Continue medical management, monitor for complications
09Warning Refractory Ascites
Diuretic-resistant or diuretic-intractable
- Cannot be mobilized despite max diuretics
- OR diuretics cause complications (HE, Cr rise, hyponatremia)
- Poor prognosis - 6-month mortality ~50%
10Decision Refractory Ascites Options
Serial LVP vs TIPS
11Action Serial Large Volume Paracentesis
Every 2-4 weeks as needed
- Albumin 8g/L for volumes >5L
- Continue diuretics if tolerated
- Quality of life consideration
12Outcome Liver Transplant Evaluation
Refractory ascites = decompensated cirrhosis, MELD exception
13Action TIPS (Transjugular Intrahepatic Portosystemic Shunt)
Consider if frequent LVP needed
- Better ascites control than serial LVP
- Contraindications: severe HE, bilirubin >5, MELD >18-20
- Covered stents preferred
- Risk: encephalopathy in 30-50%
- Path rejoins step 12Shared downstream outcome
14Action Grade 3 (Large/Tense)
Large volume paracentesis (LVP)
- LVP with albumin replacement
- Albumin 8g per liter removed (if >5L)
- Then start/optimize diuretics
- Can remove any volume safely with albumin
- Path rejoins step 05Shared downstream outcome

Individual patient factors may require deviation from these recommendations.
Known Limitations
- Refractory ascites definition requires specific criteria
- TIPS has specific contraindications
- Hyponatremia management complex
- Should refer for transplant evaluation early
