AIM： To investigate whether continuous veno-venous hemofiltration （CVVH） in different filtration rate to eliminate cytokines would result in different efficiency in acute pancreatitis, whether the saturation time of filter membrane was related to different filtration rate, and whether the onset time of CWH could influence the survival of acute pancreatitis. METHODS： Thirty-seven patients were classified into four groups randomly. Group 1 underwent low-volume CVVH within 48 h of the onset of abdominal pain （early CVVH, n = 9）. Group 2 received low-volume CVVH after 96 h of the onset of abdominal pain （late CVVH, n= 10）. Group 3 underwent high-volume CVVH within 48 h of the onset of abdominal pain （early CVVH, n = 9）. Group 4 received high-volume CVVH after 96 h of theonset of abdominal pain （late CVVH, n = 9）. CVVH was sustained for at least 72 h. Blood was taken before hemofiltration, and ultrafiltrate was collected at the start of CVVH and every 12 h during CVVH period for the purpose of measuring the concentrations of TNF-α, IL-1β and IL-6. The concentrations of TNF-α, IL-1β and IL-6 were measured by swine-specific ELISA. The Solartron 1 255 B frequency response analyzer （British） was used to observe the resistance of filter membrane. RESULTS： The survival rate had a significant difference （94.44% vs68.42%, P〈0.01） high-volume and low-volume CVVH patients. The survival rate had also a significant difference （88.89% vs 73.68%, P〈0.05） between early and late CVVH patients. The hemodynamic deterioration （MAP, HR, CVP） was less severe in groups 4 and 1 bhan that in group 2, and in group 3 than in group 4. The adsorptive saturation time of filters membranes was 120-180 min if the filtration rate was 1 000-4 000 mL/h. After the first, second and third new hemofilters were changed, serum TNF-α concentrations had a negative correlationwith resistance （r： -0.91, -0.89, and -0.86, respectively in group 1; -0.89, -0.85, and -0.76, respectively in group 2; -0.88, -0.92, and -
