Effect of Vancomycin After Catheter Replacement

Phase 4
Not yet recruiting
Conditions
Central Line-associated Bloodstream Infection (CLABSI)
Catheter-related Bloodstream Infection
Interventions
Registration Number
NCT04856878
Lead Sponsor
University of Zurich
Brief Summary

Randomized controlled trial of the effect of a single-dose intravenous Vancomycin after catheter replacement for suspected central line-associated bloodstream infection on resolution of infection in critically ill patients.

Detailed Description

Patients on the local intensive care unit with suspicion of central line-associated bloodstream infection will be randomized to standard of care consisting of catheter replacement and blood and catheter tip cultures and to standard of care plus a single-dose vancomycin. The effect of the intervention on resolution of humoral inflammation and negativity of blood cultures will be assessed after 48 and 96 hours.

Inclusion Criteria

Suspected central line-associated bloodstram infection defined as:

  • Catheterization with a non-tunneled CVC and
  • Clinical signs of local catheter infection or any increase in humoral inflammatory markers (PCT, CRP, WBC) or elevated body temperature ≥ 38.3°C not otherwise explained.

Baseline CRP at screening ≥ 100 mg/L

Exclusion Criteria
  • known positive blood cultures at the time of randomization
  • High risk situation warranting immediate empiric antibiotic therapy:
  • endovascular implant (prosthetic valve, pacemaker, vascular graft)
  • high-risk for endocarditis warranting endocarditis-prophylaxis
  • Septic shock
  • Catheter replacement not feasible or no further indication for central venous catheterization
  • Known hypersensitivity to vancomycin or any component of the formulation.
  • Administration of Vancomycin, Teicoplanin, Daptomycin or Linezolid <48 hours before enrolment.
  • Enrolment in another clinical study
  • Pregnancy
