The effect of surgical trauma on the bacterial translocation from the gut.
Bacterial translocation is the passage of viable bacteria from the lumen of the gastrointestinal tract through the intestinal mucosa to other sites. It is believed that bacterial translocation may lead to infection and septicemia. The purpose of this study was to determine what factors in experimental surgical trauma lead to bacterial translocation. Two-month-old Wistar albino rats were divided into five groups: (A) control; (B) anesthesia (ether inhalation); (C) anesthesia and surgery (median laparotomy and transient compression of the intestines); (D) fasting only; and (E) anesthesia, surgery, and fasting. After 48 hours, ileum, mesenteric lymph nodes, and blood were cultured for aerobic and anaerobic organisms. In each group the number of animals with bacteria overgrowth was calculated. The incidence of bacterial translocation to mesenteric lymph nodes and blood in groups B and D were similar to the controls (P greater than .01). There was a significant increase in the number of animals with bacterial translocation in groups C and E (P less than .001). The majority of translocating bacteria were E coli.
