Chlorhexidine Sponges, Oligon Catheters Do Not Reduce Risk of Catheter-Related Infections

Researchers recently found neither silver-impregnated or Oligon catheters nor chlorhexidine gluconate sponges helped reduce the risk of catheter-associated infections, according to a study published in Critical Care Medicine.

A total of 465 patients were assessed in this study: 156 patients in the control group, 150 patients in the chlorhexidine gluconate sponge group and 159 in the Oligon catheter group. Researchers compared outcomes of colonization and infections to see whether these interventions reduced risk of catheter-associated infections.


After two years of observation, the researchers found colonization occurred at comparable levels across standard catheters (24 cases), chlorhexidine gluconate sponges (21 cases) and Oligon catheters (25 cases). In addition, catheter-associated infections were found in nine standard catheter cases, six chlorhexidine gluconate sponge cases and seven Oligon catheter cases.
