title: Effect of surgical adhesion reduction devices on the propagation of experimental intra-abdominal infection.
abstract: OBJECTIVE
  The use of certain surgical adhesion reduction devices where there is a risk of concomitant bacterial contamination potentiates intra-abdominal infection.
  
  
  METHODS
  Evaluation of adhesion reduction devices in an experimental model of intra-abdominal infection.
  
  
  METHODS
  Experimental animal model.
  
  
  METHODS
  Adhesion reduction devices were administered at the time of bacterial challenge.
  
  
  METHODS
  Animal mortality rate, abscess formation, and bacterial counts in peritoneal fluid and blood cultures.
  
  
  RESULTS
  The use of bioresorbable membrane adhesion reduction devices in the presence or absence of antibiotic therapy did not alter the disease process as compared with appropriate control groups. However, adhesion reduction gels prepared from sodium hyaluronate and carboxymethylcellulose chemically modified with carbodiimide or ferric ion complexed sodium hyaluronate increased the incidence of peritonitis in treated animals. Gel formulations containing diimide-modified carboxymethylcellulose did not have this effect.
  
  
  CONCLUSIONS
  The use of certain adhesion reduction devices resulted in the propagation of intra-abdominal infection in an experimental rat model. This outcome was dependent on the composition of the device employed. The use of adhesion reduction devices should be tested in appropriate models of infection where there is the risk of concomitant bacterial contamination.
