title: Polymer materials for the prevention of catheter-related infections.
abstract: Catheter-related infections are major problems in medicine because of severe consequences for the patient, prolongation of hospitalization, and increasing therapy costs. Beside progress in hygienic measures, development of catheters with antiinfective properties seems to be a promising approach to the prevention of such infections. Two approaches for infection-resistant catheter materials have been developed: materials with antiadhesive properties and materials with antimicrobial properties. Antiadhesive polymers shall prevent the adhesion of microorganisms to the medical device. However, up to now there has been no material which would lead to a complete inhibition of adherence ("zero adherence"). Materials with antimicrobial properties contain antimicrobial substances which are incorporated into the biomaterial or bound to the polymer surface. These devices seem to be effective in the prevention of "early onset infections". In this paper, an overview of the development and efficiency of antiadhesive or antimicrobial polymers is given.
