OBJECTIVE The ethanol lock technique has shown great potential to eradicate organisms in biofilms and to treat or prevent central venous catheter related infections. Following instillation of ethanol lock solution, however, the inherent density gradient between blood and ethanol causes gravity induced seepage of ethanol out of the catheter and blood influx into the catheter. Plasma proteins so ...

UNLABELLED In patients with chronic gastrointestinal tract failure, requiring access to the venous system, the subsequent catheter re-insertion are leading to large veins thrombosis impeding or preventing the insertion of another catheter and exposing patients to the risk of complications. Understanding the pathophysiology of catheter-related infections, enabled to use methods allowing to eradi...

BACKGROUND & AIMS Catheter-related bloodstream infections remain the major threat for Home Parenteral Nutrition programs. Taurolidine, a potent antimicrobial agent, holds promise as an effective catheter lock to prevent such infections. Aim of the present study was to compare taurolidine with heparin, the most frequently used lock, in this respect in these high-risk patients. METHODS Thirty p...

conclusions percutaneous ethanol sclerotheraphy in simple cysts is a safe, cost-effective and minimally invasive method. we consider that this technique may be an alternative solution in the percutaneous cyst treatment. results fifty-seven cysts had complete regression, while 31 cysts regressed partially. after the procedure, pain was relieved in 44 (82%) patients and the pain alleviated in fou...

Locking of central venous catheters with heparin is an accepted practice to maintain catheter patency between dialysis sessions. However, this practice may cause other adverse reactions. Although many studies suggest benefits of other catheter lock solutions over heparin on these grounds, no consensus has been reached for clinical practice. A systematic review and meta-analysis was performed of...

Background: Prevention of catheter-related infection is of prime importance,. However, because of the risks caused by the leakage of circulating antibiotics and development of resistance to antibiotics, they are replaced by lock solutions. The aim of this study was to evaluate the efficacy and cost- effectiveness of taurolidine-citrate as a hemodialysis catheter lock solution compared to other ...

BACKGROUND Catheter-related infections are a major problem for hemodialysis patients with central venous catheters for vascular access. Catheter lock solutions containing an anticoagulant are used to maintain the patency of the catheter between hemodialysis sessions. There is evidence that the use of lock solutions containing an antibiotic is associated with lower rates of infection but also th...

BACKGROUND AND OBJECTIVES This retrospective study compared the effectiveness of the timing of the antibiotic locks to clear catheter-related bacteremia in children on chronic hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The early antibiotic lock group received antibiotic locks along with systemic antibiotics from the very beginning of catheter-related bacteremia. The late anti...

There is wide variation in the use of solutions to "lock" or fill tunneled central venous catheters for dialysis. Some centers use undiluted heparin concentrations ranging from 1000 to 10,000 U/ml and other centers place from 1000 to 10,000 U per lumen. Based on available evidence, it appears that heparin 1000 U/ml, or 4% sodium citrate are suitable choices for lock solution to maintain patency...
