Treatment of Intravenous (IV) Site Infection

Immediate Management for Peripheral IV Catheters

• The Infectious Diseases Society of America recommends removing the peripheral IV catheter immediately when infection is suspected, and submitting any drainage for culture, as this is the definitive treatment for peripheral IV site infections 1
• The Infectious Diseases Society of America suggests obtaining at least 2 separate blood cultures before initiating antibiotics if systemic infection is suspected, and culture the catheter tip semi-quantitatively after removal 2

When to Initiate Systemic Antibiotics

• The Infectious Diseases Society of America recommends initiating empirical IV antimicrobial therapy if the patient has systemic signs of infection, such as fever, chills, or hemodynamic instability 3
• The Infectious Diseases Society of America suggests that systemic antibiotics are not routinely required for simple peripheral IV site infections after catheter removal, but may be necessary for immunocompromised patients 1

Empirical Antibiotic Regimen (When Needed)

• The Infectious Diseases Society of America recommends starting vancomycin plus gram-negative coverage based on local antibiogram if systemic infection is present, with vancomycin for gram-positive coverage and a third-generation cephalosporin, carbapenem, or β-lactam/β-lactamase combination for gram-negative coverage 3

Duration of Antibiotic Therapy

• The Infectious Diseases Society of America suggests that the duration of antibiotic therapy depends on the pathogen and complications, with 5-7 days for uncomplicated coagulase-negative staphylococcal infection, 10-14 days for gram-negative bacteremia, and 4-6 weeks for persistent bacteremia or endocarditis 2, 3, 5

Special Pathogen Considerations

• The Infectious Diseases Society of America recommends always removing the catheter for Staphylococcus aureus infections, and considering transesophageal echocardiography to rule out endocarditis 3
• The Infectious Diseases Society of America suggests removing the catheter immediately for Candida species infections, and initiating amphotericin B or fluconazole therapy depending on the patient's stability and the organism's susceptibility 5

Prevention Strategies

• The Infectious Diseases Society of America recommends replacing peripheral IV catheters inserted during emergencies within 48 hours, using chlorhexidine-based skin preparation before insertion, and changing gauze dressings every 2 days and transparent dressings every 7 days 6
