Management of Ascites in Cirrhosis-Related Portal Hypertension

Dietary Sodium Restriction

All patients with cirrhosis and ascites should restrict dietary sodium to 5–6.5 g/day (87–113 mmol sodium/day), which translates to a no-added-salt diet with avoidance of precooked meals. 1 This moderate salt restriction is the cornerstone of ascites management because fluid loss and weight change are directly related to sodium balance—it is sodium restriction, not fluid restriction, that results in weight loss as fluid passively follows sodium. 1, 2

  • Nutritional counseling on sodium content should be provided to all patients with ascites. 1
  • Fluid restriction is not routinely indicated unless severe dilutional hyponatremia develops (serum sodium <125 mmol/L). 1, 2

Diuretic Regimen

First Presentation of Moderate Ascites

For patients presenting with their first episode of moderate ascites, initiate spironolactone monotherapy at 100 mg daily, increasing stepwise to a maximum of 400 mg daily if needed. 1

Recurrent or Severe Ascites

For patients with recurrent severe ascites or when faster diuresis is required (e.g., hospitalized patients), start combination therapy with spironolactone 100 mg plus furosemide 40 mg daily, increasing to maximum doses of 400 mg and 160 mg respectively. 1

  • The goal is weight loss of 0.5 kg/day in patients without peripheral edema, or 1 kg/day if edema is present. 1
  • Monitor for adverse events closely—almost half of patients experience side effects requiring dose reduction or discontinuation. 1
  • Check serum electrolytes, creatinine, and sodium regularly during diuretic therapy. 1

Diuretic Discontinuation Criteria

Temporarily discontinue diuretics if any of the following develop: 1

  • Serum sodium <125 mmol/L
  • Worsening renal function (rising creatinine)
  • Severe hypokalemia or hyperkalemia
  • Hepatic encephalopathy
  • Disabling muscle cramps

In hepatic cirrhosis with ascites, diuretic therapy should be initiated in the hospital setting, and therapy should not be started during hepatic coma or states of electrolyte depletion until the basic condition is improved. 3 Sudden alterations of fluid and electrolyte balance may precipitate hepatic coma. 3

Beta-Blocker Use in Ascites

Evolving Evidence and Caution

Refractory ascites should not be viewed as an absolute contraindication to non-selective beta-blockers (NSBB), but careful individualized assessment is required. 1 The relationship between NSBB and outcomes in advanced cirrhosis is complex and context-dependent. 4

  • NSBB may reduce the occurrence of ascites in compensated cirrhosis and have been associated with reduced risk of spontaneous bacterial peritonitis through effects on gut permeability and bacterial translocation. 5, 4
  • However, in patients with refractory ascites, hypotension, or advanced decompensation, NSBB use has been associated with increased mortality risk and worsening systemic hemodynamics. 4

The key is careful patient selection: 1

  • Monitor blood pressure and renal function closely in patients on NSBB with ascites
  • Consider discontinuation if systolic blood pressure falls below 90 mmHg or if acute kidney injury develops
  • Avoid initiation in patients with refractory ascites and hemodynamic instability

Large Volume Paracentesis (LVP) with Albumin

Indications and Technique

Therapeutic paracentesis is indicated for tense ascites causing respiratory compromise or significant discomfort. 1

  • Obtain informed consent before the procedure. 1
  • Ultrasound guidance should be considered when available to reduce adverse events. 1
  • Routine measurement of prothrombin time and platelet count before paracentesis is not recommended, and prophylactic blood product infusion is not indicated. 1

Albumin Replacement Protocol

Albumin (20% or 25% solution) should be infused after paracentesis of >5 L is completed, at a dose of 8 g albumin per liter of ascites removed. 1 This is a high-quality recommendation based on strong evidence. 1

  • For paracentesis <5 L, albumin can be considered in patients with acute-on-chronic liver failure (ACLF) or high risk of post-paracentesis acute kidney injury. 1
  • The albumin infusion prevents paracentesis-induced circulatory dysfunction by maintaining intravascular volume and oncotic pressure. 6, 7

Long-Term Albumin Therapy

Emerging evidence suggests that long-term albumin infusion may improve survival in patients with cirrhosis and ascites. 5, 8 The ANSWER trial demonstrated prolonged overall survival with chronic albumin administration, though the ATTIRE and MACHT trials showed mixed results with some patients developing pulmonary edema. 7

  • Long-term albumin (40 g twice weekly) may reduce further decompensation events in selected patients with ascites. 5, 8
  • This approach is still being refined and should be considered on a case-by-case basis. 8

Transjugular Intrahepatic Portosystemic Shunt (TIPS)

Indications

TIPS should be considered in patients with refractory ascites (ascites that cannot be mobilized or recurs rapidly after therapeutic paracentesis despite maximal diuretic therapy). 1 This is a high-quality, strong recommendation. 1

  • TIPS may improve survival in selected patients in addition to controlling ascites. 8
  • TIPS is also indicated for hepatic hydrothorax after multidisciplinary discussion. 1

Contraindications and Caution

Exercise caution when considering TIPS in patients with: 1

  • Age >70 years
  • Serum bilirubin >50 μmol/L (approximately 3 mg/dL)
  • Platelet count <75×10⁹/L
  • MELD score ≥18
  • Current hepatic encephalopathy
  • Active infection
  • Hepatorenal syndrome

These factors predict poor outcomes and increased risk of post-TIPS complications, particularly hepatic encephalopathy. 1

Second-Line and Adjunctive Therapies

Midodrine

Midodrine may be considered in refractory ascites on a case-by-case basis. 1 This alpha-agonist can improve systemic hemodynamics in patients with cirrhosis and ascites, though evidence is limited. 1

Norfloxacin Prophylaxis

Norfloxacin prophylaxis reduces the risk of spontaneous bacterial peritonitis and may improve survival in selected high-risk patients with ascites. 5

Low-Flow Ascites Pump

For patients with intractable ascites who are not TIPS candidates, low-flow ascites pump insertion may be an option. 8 This is an emerging therapy for highly selected patients. 8

Management of Hyponatremia in Ascites

Fluid Restriction Indications

Fluid restriction to 1–1.5 L/day should be reserved for patients with severe hyponatremia (serum sodium <125 mmol/L) who are clinically hypervolemic. 1

  • Fluid restriction is often ineffective in improving sodium levels and compliance is poor. 1, 2
  • Sodium restriction, not fluid restriction, is the primary driver of weight loss in cirrhotic ascites. 1, 2

Hypovolemic Hyponatremia Management

If hypovolemic hyponatremia develops during diuretic therapy (evidenced by rising creatinine, orthostatic hypotension), discontinue diuretics and expand plasma volume with normal saline. 1

Severe Symptomatic Hyponatremia

Hypertonic sodium chloride (3%) administration should be reserved for severely symptomatic acute hyponatremia (seizures, altered mental status). 1

  • Serum sodium should be corrected slowly—never exceed 8 mmol/L correction in 24 hours to prevent osmotic demyelination syndrome. 1, 9
  • In cirrhotic patients, aim for even more conservative correction of 4–6 mmol/L per day. 9, 10

Special Considerations for Spontaneous Bacterial Peritonitis (SBP)

In patients with SBP and elevated or rising serum creatinine, infuse albumin 1.5 g/kg within 6 hours of diagnosis, followed by 1 g/kg on day 3. 1 This reduces the risk of hepatorenal syndrome and improves survival. 1

Common Pitfalls to Avoid

  • Do not restrict fluid in patients with normal serum sodium (>125–130 mmol/L)—sodium restriction alone is sufficient. 2
  • Do not continue diuretics when serum sodium falls below 125 mmol/L or when acute kidney injury develops. 1, 10
  • Do not use hypertonic saline beyond initial stabilization in hypervolemic hyponatremia—it worsens ascites without improving outcomes. 10
  • Do not correct chronic hyponatremia faster than 6–8 mmol/L in 24 hours in cirrhotic patients—osmotic demyelination is often fatal in this population. 9, 10
  • Do not initiate diuretics during hepatic coma or severe electrolyte depletion—stabilize the patient first. 3
  • Do not routinely check coagulation parameters or transfuse blood products before paracentesis—this is unnecessary and not evidence-based. 1
