How is ascites managed in cirrhosis, including diuretic strategy and paracentesis considerations?

Managing ascites in cirrhosis focuses on reducing sodium and water retention while maintaining circulatory stability, with paracentesis reserved for symptom relief or large-volume fluid removal. The best approach combines dietary sodium restriction with a diuretic regimen started to counteract the hyperaldosteronism seen in cirrhosis. Spironolactone, a potassium-sparing diuretic that blocks aldosterone’s effects, is used first because it directly targets the pathophysiology of fluid retention. To enhance natriuresis and prevent electrolyte imbalance, a loop diuretic such as furosemide is added, aiming for roughly a 2:1 ratio of spironolactone to furosemide. This balance helps achieve gradual weight loss and fluid removal while protecting kidney function and potassium levels. In patients whose ascites remains uncontrolled despite optimized diuretics (refractory ascites), large-volume paracentesis provides effective relief, and giving intravenous albumin during the procedure helps maintain circulating blood volume and reduces paracentesis-related circulatory dysfunction. Context helps: cirrhosis causes splanchnic vasodilation and activation of the neurohumoral systems, leading to sodium and water retention despite low effective arterial blood volume. Diet reduces fluid intake, while spironolactone tackles the aldosterone-driven sodium retention and furosemide accelerates salt and water excretion. When large amounts of fluid are removed, albumin infusion preserves intravascular volume and prevents complications. Monitoring is essential—watch renal function, electrolytes, and weight progression—to avoid rapid diuresis or electrolyte disturbances. In cases where diuretics and paracentesis are not enough, advanced options like TIPS or transplant may be considered.
