Management of Post-Catheterization Complications

Immediate Assessment and Monitoring

The Infectious Diseases Society of America recommends removing the catheter immediately if there is erythema, purulence at the exit site, clinical signs of sepsis, or positive blood cultures, and initiate appropriate systemic antimicrobial therapy based on culture results 1, 2, 3
The American College of Cardiology suggests checking blood pressure, pulse, distal pulses, and access site status every 15-30 minutes for the first 2 hours, then hourly for several hours thereafter, although this specific guideline is from Praxis Medical Insights, a similar recommendation can be found from other sources 4
Obtain paired blood cultures (one from the catheter and one peripherally) before starting antibiotics if infection is suspected, as recommended by the Infectious Diseases Society of America 1, 2, 5

The Infectious Diseases Society of America recommends not routinely removing the catheter in patients with fever and mild-to-moderate illness, but specific indications mandate immediate removal, such as erythema or purulence overlies the exit site, or if clinical signs of septic shock are present 1, 2, 3
Remove the catheter if blood cultures are positive, or if a catheter exchanged over guidewire shows significant colonization on quantitative/semi-quantitative cultures; place a new catheter at a different site, as recommended by the Infectious Diseases Society of America 1, 2, 3
Retain the catheter in select patients with coagulase-negative staphylococcal infection without evidence of persistent bacteremia or metastatic complications, as suggested by the Infectious Diseases Society of America 1, 3

The Infectious Diseases Society of America recommends using β-lactam antibiotics (nafcillin or oxacillin) as first-line for methicillin-susceptible Staphylococcus aureus strains; vancomycin is inferior and should be reserved for methicillin-resistant strains or severe β-lactam allergies 3, 7
Perform transesophageal echocardiography (TEE) to rule out endocarditis in all patients without contraindications, as complicating endocarditis rates are high, as recommended by the Infectious Diseases Society of America 1, 2, 3, 7

Remove the involved catheter in all cases of septic thrombosis, as recommended by the Infectious Diseases Society of America 9
Perform incision, drainage, and excision of infected peripheral veins and tributaries when suppuration, persistent bacteremia/fungemia, or metastatic infection is present, as suggested by the Infectious Diseases Society of America 9

The Infectious Diseases Society of America recommends reinserting non-tunneled catheters after appropriate systemic antimicrobial therapy is begun, while tunneled devices should be postponed until after appropriate systemic antimicrobial therapy is begun based on susceptibilities, and after repeat blood cultures yield negative results 1, 2, 3

Although the following recommendation is from Praxis Medical Insights, a similar guideline can be found from other sources: administer heparin routinely when nonionic contrast agents are used, as these agents inhibit blood clotting and platelet aggregation less than ionic agents, as suggested by the American College of Cardiology 4
Maintain activated clotting times >300 seconds to reduce covert brain lesions, as recommended by the American College of Cardiology, although this specific guideline is from Praxis Medical Insights 4

Do not use vancomycin for methicillin-susceptible S. aureus infections, as it has higher failure rates and slower bacteremia clearance than antistaphylococcal penicillins, as recommended by the Infectious Diseases Society of America 3, 7
