Objective To investigate the effect of individualized and comprehensive therapy in treatment of severe acute pancrea-titis in early stage for preventing MODS .Methods 85 patients with severe acute pancreatitis treated in this Chengde medical college affiliated hospital from January 2008 to January 2012 were divided into two groups .The control group included 42 patients ,all used conventional basic treatment ;the test group included 43 patients ,and all used individualized and comprehensive therapy in early stage .The APACHEⅡ ,MODS and Ranson scores ,and serum inflammatory cytokines indexes of patients in each group before and after admission were all recorded .Results The APACHEⅡ and MODS scores after admission of test group were significantly low-er than the control group(P< 0 .05) .The TNF α,CRP and IL 10 after admission of two groups had significant difference (P<0 .05) .The MODS incidence of control group was 64 .3% (27/42) ,pancreatic encephalopathy incidence was21 .4% (9/43) ,the inci-dence of pancreatic infection was 33 .3% (14/42) ,hospital mortality incidence was 19 .1% (8/42) and length of hospital stay was (30 .4 ± 5 .7) d .The MODS incidence of test group was 27 .9% (12/43) ,pancreatic encephalopathy incidence was11 .6% (5/43) , pancreatic infection rate was 14 .0% (6/43) ,hospital mortality incidence was 4 .7% (2/43) and length of hospital stay was (23 .5 ± 4 .3) d .The incidence of MODS ,hospital mortality and pancreatic infection rates of test group were significantly lower than that of the control group (P<0 .05) .The average length of stay of test group were significantly lower than the control group (P<0 .05) . Conclusion To use individualized and comprehensive therapy in treatment of severe acute pancreatitis in early stage can reduce MODS ,protect organ function ,and reduce mortality .
