Abstract

Paired quantitative blood cultures collected simultaneously via catheter and peripheral vein in Isolator 1.5 ml tubes, were performed in 50 febrile hematology children. Samples were taken to diagnose catheter-related sepsis (CRS) without catheter removal and to monitor the therapeutic efficiency of antimicrobials administered through the infected device by infusion and/or by the antibiotic lock technique (ALT). In 7 children (14%) the colony counts from catheter blood samples were 30-fold higher than the colony counts from peripheral samples, suggesting CRS; in 7 other patients (14%), identical colony counts in both samples suggested sepsis was not catheter-related. One patient (2%) had septicemia caused byE. coli found in the urinary tract; only the peripheral blood cultures were positive. In 6 patients (12%), the Isolator system was not effective for diagnosing bacteremia or CRS; in 29 patients (58%) the febrile episode was not microbiologically documented. All episodes of CRS were cured whatever the treatment was: infusion or ALT.
