Abstract
Intravascular catheters are increasingly important causes of nosocomial infections. Catheter related complications range from local exit site or tunnel infections to frank bacteremias. A semiquantitative method of culture of central venous catheters (CVC) was done in our hospital from January to December 1996. A total of 119 catheter tips sent to the Microbiology Department were cultured and 11 (9.24%) showed significant growth with associated blood stream infection. 14 (11.76%) of the CVCs showed scanty or less than 15 colonies in roll or contents and there was no associated blood stream infection. 7 (5.88%) showed moderate to heavy growth in roll and contents and there was no blood stream infection. The age groups ranged from 2 months to 66 years. The results of the study indicate that Gram negative organisms formed the predominant isolates. Gram negative isolates included Klebsiella species, Enterobacter species, E. coli species, Serratia and non-fermenting Gram negative bacilli. Coagulase negative staphylococcus which is often believed to be an important pathogen was not associated with bacteremia or septicemia in our hospital, during this study period. Considering the fact that 1553 operations were performed during the study period, the infection rate through CVC's would work out to a negligible 0.71%.
