Overview
Infection of vascular catheters, also known as central line-associated bloodstream infections (CLABSI), occurs when microorganisms enter the bloodstream through a catheter insertion site, posing significant risks to patients undergoing invasive procedures 1.Diagnosis
Clinical signs include fever, chills, and elevated white blood cell count 1.
Positive blood cultures are essential for definitive diagnosis 1.
Imaging studies (e.g., ultrasound) may help identify catheter-related thrombosis or extravasation 1.Management
Removal of the infected catheter is often necessary 1.
Antimicrobial therapy tailored to blood culture results is crucial 1.
First-line antibiotics typically include vancomycin (15-20 mg/kg every 12 hours) for gram-positive coverage and an aminoglycoside or a fluoroquinolone for gram-negative coverage 1.
Adjunctive treatments may include catheter replacement with strict aseptic technique post-infection 1.Special Populations
No specific details provided regarding pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.Key Recommendations
Remove the infected central venous catheter promptly to reduce infection spread (Evidence: Expert opinion) 1.
Initiate targeted antimicrobial therapy based on blood culture results to ensure appropriate pathogen coverage (Evidence: Moderate) 1.
Implement strict aseptic techniques during catheter replacement to prevent recurrence (Evidence: Expert opinion) 1.References
