Tzianabos AO, Cisneros RL, Gershkovich J, et al. Effect of Surgical Adhesion Reduction Devices on the Propagation of Experimental Intra-abdominal Infection. Arch Surg. 1999;134(11):1254–1259. doi:10.1001/archsurg.134.11.1254
The use of certain surgical adhesion reduction devices where there is a risk of concomitant bacterial contamination potentiates intra-abdominal infection.
Evaluation of adhesion reduction devices in an experimental model of intra-abdominal infection.
Experimental animal model.
Adhesion reduction devices were administered at the time of bacterial challenge.
Main Outcome Measures
Animal mortality rate, abscess formation, and bacterial counts in peritoneal fluid and blood cultures.
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.
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.
