| Summary: | Abstract Background Large-volume paracentesis (LVP) is a main pillar in treating patients with tense ascites. Without plasma expanders use, paracentesis-induced circulatory dysfunction (PICD) is a common complication with decreased survival. The aim was to compare low-dose albumin (2 g/L ascitic fluid removed n = 85) with standard-dose albumin (6 g/L ascitic fluid removed, n = 25) for prevention of PICD. Liver function tests, urea, creatinine, CBC, and abdominal ultrasonography were done. Plasma renin activity (PRA) was measured at baseline and on the 6th day post-LVP. The delta change (Δ) = day 6 variable minus baseline variable value. PICD was defined as increase in PRA of > 50% of the baseline value. Results Patients in low-dose albumin group were mainly Child B compared with Child C (85.9% vs. 52%; p = 0.001), underwent less paracentesis volume (9.78 ± 3.56 vs. 12.52 ± 3.6 L; p = 0.001), but had higher baseline PRA (859.62 ± 1151.34 vs. 165.93 ± 95.34 pg/mL; p = 0.001). In both groups, the PRA increased at day 6 compared with the baseline (1141.57 ± 1433.01 vs. 859.62 ± 1151.34 pg/mL; p = 0.01) and (192.21 ± 80.99 vs. 165.93 ± 95.34 pg/mL; p = 0.01) respectively. Both groups were comparable for Δ PRA (281.95 ± 851.4 vs. 26.28 ± 30.2 pg/mL; p = 0.102) and PRA percent increase (10.97 ± 30.77 vs. 12.57 ± 14.87; p = 0.844). They had comparable PICD incidence (24.7% vs. 12%; p = 0.27). Females were more liable for PICD occurrence than males (OR 2.91, 95% CI 1.125–7.547, p = 0.028) and so Child B patients than Child C (OR 8.4, 95% CI 1.072–65.767, p = 0.043). Conclusion Low-dose albumin infusion is comparable to the standard-dose albumin for the prevention of PICD.
