title: Practical approach to catheter-related bloodstream infections in paediatrics.
abstract: Catheter-related bloodstream infections (CRBIs) are a common problem in paediatrics. Sterile insertion and proper care of the catheter is likely more important than the type of catheter in determining the rate of CRBIs. The accuracy of the diagnosis of CRBIs can be improved by comparing the time to positivity or the concentration of organisms in blood drawn through the catheter with blood drawn from other sites, or by changing the catheter over a guidewire and culturing the removed catheter. When a CRBI is suspected, the catheter should be removed if it is no longer required, the child is hemodynamically unstable, there are metastatic foci of infection, the infecting organism is Candida or a mycobacterium, or there is a tunnel infection. The necessity for catheter removal is controversial if the infecting organism is Staphylococcus aureus or a Gram-negative organism. In most other situations, the catheter only needs to be removed if bacteremia persists despite appropriate antibiotic use.
