Strategy of treatment with high-volume hemofiltration on severe acute pancreatitis and fulminant acute pancreatitis / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate strategy of treatment of hemofiltration on severe acute pancreatitis (SAP) and fulminant acute pancreatitis (FAP).</p><p><b>METHODS</b>One hundred and thirty patients with SAP and eighty-one patients with FAP treated with hemofiltration (HF) were prospectively observed from March 1997 to December 2008. Indications for HF, variables (time interval for hemofiltration), mode, therapeutic dosage, blood rate, heparin dosage and components of hemofiltration, therapeutic efficacy (time of disapearance of abdominal pain, intra-abdominal pressure and survival rate) and complications (incidence of bleeding and blood infection).</p><p><b>RESULTS</b>All patients underwent high volume hemofiltration (HVHF) or hemodialysis-filtration (HDF) within 72 hours after onset of the disease. Dose of SAP and FAP was (53 +/- 6) mlxkg(-1)xh(-1) and (59 +/- 10) mlxkg(-1)xh(-1) (P < 0.05), respectively. Rate of short veno-venous hemofiltration in SAP (76.9%) was higher than that of FAP (38.3%) (P < 0.05); however, rate of continuous veno-venous hemofiltration (23.1%) was lower than that of FAP (37.0%) (P < 0.05). Rate of HDF was much higher in FAP than that of SAP. Low molecular weight heparin and heparin were both available to anticoagualte;but dosage required in patients with FAP was much higher than that of SAP (P < 0.05). Time intervals for amelioration of abdominal pain in SAP and FAP were (9 +/- 6) h and (15 +/- 10) h, respectively. Itra-abdominal pressure was decreased significantly at the end of hemofiltration compared to prior to hemofiltration in SAP and FAP (P < 0.05). Level of serum triglyceride decreased abruptly after adsorption (P < 0.05). Rate of operation within 28 days in SAP (73.8%) was lower than FAP (87.7%). The in-hospital survival rates in SAP and FAP were 88.5% and 67.9%, respectively. Amount of platelet decreased in patients with blood flow rate less than 240 ml/min was higher than that of more than 240 ml/min (P < 0.05). And incidence of blood stream infection and bleeding increased significantly (P < 0.05).</p><p><b>CONCLUSIONS</b>HVHF and HDF used in SAP and FAP patients underwent conservative treatment within 72 hours, respectively, can increase survival rate significantly.</p>
