Bacterial contamination of radial artery catheters.
A prospective survey of 113 radial artery catheters showed a total contamination rate using an enrichment media culturing technique of 39%. The yield from routine culturing alone was only 9%. In six cases pathogenic bacteria were isolated. In this study no correlation between contamination and aspects of catheter insertion and management was shown.
