Catheter-related bloodstream infection

Definition

Catheter-related bloodstream infection (CRBSI) is an infection that occurs when bacteria or fungi enter the bloodstream through a central venous catheter. It is a serious condition often associated with hospital settings and can lead to severe complications.

5 Must Know Facts For Your Next Test

1. CRBSIs are commonly caused by organisms like Staphylococcus aureus, coagulase-negative staphylococci, and Candida species.
2. Symptoms typically include fever, chills, and hypotension, which may indicate sepsis if not promptly treated.
3. Diagnosis of CRBSI involves blood cultures from both the catheter and peripheral veins showing identical pathogens.
4. Preventative measures include strict aseptic techniques during catheter insertion and maintenance.
5. Treatment usually involves the removal of the infected catheter and administration of appropriate antibiotics or antifungal agents.
