[Further comment on central venous catheter infections].
Many reports from the surgical literature document the incidence of catheter related sepsis varies between 1 and 10 per cent. In many instances sepsis is secondary to contamination from normal saprophyte cutaneous bacteria. In our Institute we set down a standardized methodology to reduce the contamination of venous central access from cutaneous bacteria. Of 31 patients studied, none had bacteria in the last 5 cm of central venous catheter, 2 had streptococcus alpha haemolytic colonies and coagulase negative staphylococcus colonies at the same time on skin over the region of venepuncture. With our paper we had attained one's awareness that it is very difficult to obtain zero per cent in contamination of central venous catheter, mainly in immunodepressed or critical patients, but with careful dressing and with new technology it is possible to reduce the contamination and following sepsis.
