A highly concentrated tigecycline lock solution ensuresin vivoactivity against staphylococcal catheter-related infections

Concentrated Sodium Citrate (23%) for Catheter Lock.

For chronic central venous dialysis catheters, the standard method for maintaining catheter patency between treatments is to instill (lock) catheters with 5000 - 10 000 units of heparin in each lumen. Sodium citrate (citrate) is an anticoagulant with intrinsic antibacterial activity (at 20% concentration or higher). Citrate has only transient anticoagulant effects if accidentally infused to the...

Minocycline-EDTA lock solution prevents catheter-related bacteremia in hemodialysis.

There is growing concern about the development of antibacterial resistance with the use of antibiotics in catheter lock solutions. The use of an antibiotic that is not usually used to treat other serious infections may be an alternative that may reduce the clinical impact should resistance develop. We conducted a randomized controlled trial to compare a solution of minocycline and EDTA with the...

Taurolidine-citrate-heparin catheter lock solution reduces staphylococcal bacteraemia rates in haemodialysis patients.

BACKGROUND Infection is second only to cardiovascular disease as a cause of death in the haemodialysis (HD) population. AIM : To assess the effect of introducing catheter lock solution taurolidine-citrate-heparin to all tunnelled central venous catheters (TCVCs) on staphylococcal bloodstream infection rates in patients on chronic HD. DESIGN Observational, prospective analysis of the inciden...

Catheter lock solutions influence staphylococcal biofilm formation on abiotic surfaces.

BACKGROUND Microbial biofilms form on central venous catheters and may be associated with systemic infections as well as decreased dialysis efficiency due to catheter thrombosis. The most widely used anticoagulant catheter lock solution in the US is sodium heparin. We have previously shown that sodium heparin in clinically relevant concentrations enhances Staphylococcus aureus biofilm formation...
