[Massive paracentesis and administration of dextran 70 vs albumin in cirrhotic patients with tense ascites]

Some studies have demonstrated that paracentesis for large-volume extraction of ascites produces renal failure and hyponatremia, and intravenous infusion of plasma expanders can overcome this complications. We performed a survey where we compared effectiveness of dextran 70 vs albumin on prevention of adverse effects and cost differences. Two random groups were formed, 8 cirrhotic patients with tense ascites in each group. Paracentesis with extraction of more than 5 liters was performed. The group A received human albumin and group B dextran 70, both received 6 g per liter of extracted liquid. 24 hours before and 48 hours after of ascites extraction, we performed hepatic function test, blood chemistry with renin and aldosterone. Clinical results and biochemistry test were similar in both groups without statistical significance (p > 0.05). Amount of plasma expander was almost the same, but the cost in group A was $266 USD and in group B $20.8 USD. Azotemia was present in 12.5% in group A and hyponatremia in 12.5% in both groups, without symptoms. The results show that dextran 70 produces the same effect like albumin in the treatment of ascites after large-volume paracentesis with lower cost.
