Abstract
Catheter-related bacteremias carry high mortality rates in hematological patients. When a multidrug-resistant microorganism is involved, the catheter should ideally be removed; however, this approach is not always possible. Tigecycline lock therapy was used in two pediatric oncohematological patients with intravascular catheter-related infection due to KPC-producing Klebsiella pneumoniae. The catheter was salvaged in both cases, and the patients were later discharged. Our experience suggests the usefulness of this approach in treating this type of infection.
