IV lock solution for central venous catheter salvage

0

We report several cases of catheter salvage using antibiotic lock solution in staphylococcal bacteremia with the purpose of stimulating the interest in randomized clinical trials. Evaluating the risk and benefits of catheter salvage in this patient subset in light of optimized systemic antibiotic dosing, improved lock solution use, and multidisciplinary involvement, balanced with the critical need to prevent unnecessary vascular trauma, is of great importance” El Nekidy et al (2018).

Abstract:

Catheter-related blood stream infections comprise a major concern in hemodialysis patients, leading to increased mortality, morbidity, and cost of treatment. Prompt appropriate systemic antibiotics treatment, which includes administration of appropriate systemic antibiotics and, frequently, catheter removal and replacement, is warranted. However, in hemodialysis patients, repeated catheter insertions may cause central vein stenosis and thrombosis which limits the future availability of hemodialysis access. Lock solutions containing antibiotics and anticoagulants, instilled directly into the catheter lumen after each dialysis, have been successfully utilized for catheter salvage but higher rates of recurrence and complications were observed in infections resulting from staphylococcal species. We report several cases of catheter salvage using antibiotic lock solution in staphylococcal bacteremia with the purpose of stimulating the interest in randomized clinical trials. Evaluating the risk and benefits of catheter salvage in this patient subset in light of optimized systemic antibiotic dosing, improved lock solution use, and multidisciplinary involvement, balanced with the critical need to prevent unnecessary vascular trauma, is of great importance.
