To investigate the effect of different abdominal lavage fluid on bacterial translocation in acute hemorrhagic necrotizing pancreatitis (AHNP) of rat model.One hundred and sixty Wistar rats were randomly divided into the control group, AHNP group, antibiotics group and Chinese drugs group. The treated group were treated with intraperitoneal lavage for 72 hours. The peritoneal fluid and blood samples were collected for bacterial culture. Pancreas were examined histopathologically.In Chinese drugs group, the pathologic damage in pancreas were milder than that of AHNP group, and as compared with AHNP group, the bacterial positive rates of blood and peritoneal lavage fluid culture were reduced from 80% to 40% and 90% to 40% respectively.AHNP impaired the gut barrier function which led to bacterial translocation from the gut to other organs. It plays an important role in intestinal infection secondary to AHNP. Abdominal lavage with Chinese drugs is effective in preventing intestinal bacterial translocation, it showed its protection on gut barrier function by alleviating the damage of intestinal mucosa and pancreatitis.
