Prevention of catheter-related infections: the potential of a new nano-silver impregnated catheter.
Contaminated or infected catheters are a major source of nosocomial infections responsible for >40% of all episodes of nosocomial sepsis in acute-care hospitals. Antibiotics as well as surface modifications with, for example, hydrogels proved to be of little value in preventing the contamination of indwelling catheters. The even distribution of 10(12-13) activated silver nanoparticles per gram in various polymers, e.g. polyurethane and silicone, results in an excellent antimicrobial activity against a broad spectrum of organisms in vitro. Substantial reduction of incrustation of these catheters was also observed. These preliminary experimental data warrant clinical studies.
