Paracentesis with Dextran 70 vs. paracentesis with albumin in cirrhosis with tense ascites. Results of a randomized...

Forty-one patients with cirrhosis and tense ascites were randomized to receive daily paracentesis of 5 liters associated with Dextran 70 as volume expander (6 g for each 1000 ml of ascites removed) (group I = 20 patients) or paracentesis with albumin (6 g for each 1000 ml of ascites) (group II = 21 patients). The basal clinical features, laboratory data, and plasma renin activity were similar in both groups. The volume of ascites removed was 12.9 +/- 4.4 and 10.9 +/- 3.7 liters in group I and II, respectively (n.s.). No significant changes were observed in liver and renal function tests, KPTT, platelet count, factor VIII, serum electrolytes or plasma renin activity 24 and 96 h after the last paracentesis in both groups, except for a decrease in bilirubin in group I and a transient increase of serum albumin in group II. Four patients developed complications in each group, mainly hyponatremia, while one patient in each group developed renal impairment. One patient from group I died with hepatic encephalopathy. Moreover, the probability of survival and readmission to the hospital because of tense ascites were similar in both groups of patients during the follow-up. The treatment cost with Dextran 70 was 15.50 dollars vs. 364.30 dollars with albumin for each patient treated. These results indicate that repeated large volume paracentesis associated with Dextran 70 is as effective and safe as paracentesis associated with albumin in cirrhotic patients with tense ascites. However, due to its reduced cost, paracentesis with Dextran 70 may be considered the treatment of choice in cirrhotic patients with tense ascites without liver cancer and renal failure.
