Management of Hepatic Ascites with Diuretics

Introduction to Diuretic Therapy

The American Association for the Study of Liver Diseases recommends that intravenous administration of diuretics is not used for managing hepatic ascites as it can cause kidney damage due to sudden body fluid loss 1

Oral administration of diuretics is the standard approach for managing ascites in cirrhotic patients 1
Spironolactone is the primary diuretic for cirrhotic ascites, with a recommended starting dose of 50-100 mg/day (oral) 2, 3
Furosemide is used as an adjunctive therapy at a starting dose of 20-40 mg/day (oral) 2, 3

When using diuretics, regular monitoring is essential for changes in body weight 5
Regular monitoring is also necessary for vital signs 2
Serum creatinine levels should be monitored 5
Sodium and potassium levels should be monitored 1
Diuretics should be reduced or stopped if hepatic encephalopathy occurs 5
Diuretics should be reduced or stopped if severe hyponatremia (below a certain level) occurs 5
Diuretics should be reduced or stopped if acute kidney injury occurs 5
Loop diuretics should be reduced or stopped in case of low potassium levels 2
Aldosterone antagonists should be reduced or stopped in case of high potassium levels 2

For patients with tense ascites, large-volume paracentesis with albumin infusion is more effective than diuretics alone 2, 5
After paracentesis, maintenance therapy with oral diuretics should be continued to prevent reaccumulation of fluid 5
