Abstract

Objective To explore the therapeutic effect of continuous veno-venous hemofiltration (CVVH) on the treatment of severe acute pancreatitis (SAP).Methods All data about forty-five patients with SAP admitted to the intensive care unit (ICU) from June 2005 through June 2010 were reviewed.These 45 patients were randomly (random number ) divided into routine treatment group (n =22 ) and comprehensive treatment group ( n =23 ).In control group,patients were rapidly given with a suffficient liquid support,vasoactive drug to increase organ perfusion,trypsin secretion inhibitor,broad-spectrum antibiotics,enteral nutrition with intestine membrane protective agent in early stage.In the comprehensive treatment group,patients received CVVH integrated with routine treatment.On admission and 72 h posttreatment,the scores of acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) and multiple organ dysfunction syndrome (MODS),and the results of standard bettery of biochemistry tests indcluding blood urea nitrogen (BUN),serum cratinine (Scr),total bilirubin (TBIL),alanine aminotransferase (ALT),amylase (AMS),C-reactive protein (CRP),TNF-α,IL-6,IL-8 were observed.Time of mechanical ventilation support,length of ICU stay,and survival rate were compared between two groups.Results On admission between the two groups,no statistical significance was seen in the APACHE Ⅱ and MODS score,BUN,Scr,TBIL,ALT,AMS,CRP,TNF-α,IL-6,IL-8 (P > 0.05).But APACHE Ⅱ and MODS score were decreased significantly in comprehensive treatment group than in the routine treatment group,as well as the the level of BUN,Scr,TBIL,ALT,AMS,TNF-α,IL-6,IL-8 and CRP after 72h post-treatment (P<0.05 ).In routine treatment group and comprehensive treatment group,the time of respirator intervention and length of stay in ICU were (7.6±3.4) d vs.(11.5±4.7) d,(12.3±7.8) dvs.(17.6±9.2) d respectively,the statistical significance was shown ( P < 0.05 ).Compared to the comprehensive treatment group ( 86.96% ),the survival rate ( 59.09% ) were lower in routine treatment group ( P < 0.05 ).Conclusions CVVH combined with routine treatment,which can remove inflammatory agents and toxins,maintain homoeostasis,and improve oxygenation,is effective in treatment of SAP and can improve patient survival rate.
