[Catheter induced septicaemia]

The most serious catheter-related infections, such as septicaemia are associated with the central venous catheters rather than the peripheral catheters. The main sources of microorganisms are the patient's skin and hospital environment. Bacteria can gain access to blood via the external or the internal catheter surfaces. A number of approaches for the prevention of sepsis associated with catheters have been proposed, with limited success. Beside the careful aseptic techniques, the development of antibacterial polymers offers the greatest potential for further reduction of risk of catheter-related sepsis. However, there is evidence suggesting that an appropriate training of staff in the management and care of catheters is fundamental to achieve a reduction in the incidence of catheter-related infections.
