Reducing central venous catheter infections

This article reviews the current literature in relation to the management of central venous catheters and the prevention of catheter related infection. Sources and factors influencing catheter related infection are reviewed. In some areas of catheter management, there are clear recommendations such as the choice of skin preparation and catheter site. Other areas don't have clear guidelines; this results in varying practices and the need for further research. The latest research has been in the areas of impregnated catheters with studies showing some benefits. Recent research has also analysed the effect of the method of fluid and line changes as well as their frequency in relation to catheter related infections. A summary is given outlining interventions which have evidence supporting their practice in the reduction of catheter related infections along with interventions which may be effective in reducing catheter related infection and the need for further research.
