The effect of selective bowel decontamination and mechanical bowel preparation on bacterial translocation due to intraabdominal hypertension

BACKGROUND: The objective of our study is to evaluate the preventive effects of selective digestive decontamination (SDD) and mechanical bowel preparation in rats with experimentally induced bacterial translocation. METHODS: Fourty adult male Sprague Dowley rats weighing 250-300 g. were divided equally into four groups as Group 1 (sham [control]), Group 2 (experimentally induced IAH at 19 mmHg), Group 3 ( SDD group) and Group 4 (SDD and mechanical bowel preparation with 19 mmHg intraabdominal pressure). Group 3 and 4 were treated at 12 hours intervals with oral gentamycine 5 mg/kg and IM sefotaxime 100mg/kg Mechanical bowel preparation was performed by oral administration of sodium phosphate. After 24 hours all rats were sacrified; mesenteric lymph nodes, spleen and liver biopsy specimens were harvested aseptically. Specimens were diluted and cultured in McConkey medium and the colony-forming units (CFU/gr ) were calculated. RESULTS: In Kruskal Wallis tests there were no significant differences between Group 1 and 3 or 4, and also Group 3 and 4 (p>0.05, p=0.872 respectively), while differences between Group 1 and 2, and also Group 3 and 4 were statistically significant (p<0.001) with respect to CFU/g estimates. CONCLUSION: These data indicate that selective intestinal decontamination and mechanical bowel preparation prevent bacterial translocation due to intraabdominal hypertension.
