Evidence-based prevention of catheter infection during parenteral nutrition

Parenteral nutrition is a risk factor for catheter-related bloodstream infection. Here we reviewed strategies for the prevention of catheter-related infections, which always must begin with the cornerstone of prevention: the strict adherence to aseptic techniques. Most research has been interested in coated catheters. From these results, it may be concluded that antibiotics or antiseptic-impregnated catheters, like those with minocycline-rifampicin or chlorhexidine/silver sulfadiazine, significantly reduce catheter-related blood stream infections. Antibiotics or antiseptic-impregnated central venous catheters may even result in cost saving in intensive care units. Antiseptic or antibiotic-lock techniques would also be of interest to prevent catheter-related sepsis in high-risk patients who are receiving parenteral nutrition.
