Alcohol Locks for the Prevention of Tunneled Catheter-related Infections

• Status: Completed
• Trial end date: 2009-09-01
• Target enrollment: 0
• Participant gender: All

Summary

In modern-day medicine, the use of central venous catheters has become unavoidable. However, their use does not come without risk. It puts patients in danger of infectious complications (catheter-related infections [CRI]), the most important of which is catheter-related bloodstream infection (CRBSI). CRBSI is associated with a significant increase in hospital stay and, therefore, cost of patient management, morbidity, and probably also mortality. There still is an urgent need for effective, cheap and easy to implement measures to prevent CRI that are without risk of developing antibiotic resistance.

During use, bacteria can colonize the inner surface of the catheter. This endoluminal route of infection can be prevented to some extent when an antibiotic solution is instilled in the catheter for a long enough time and on a regular basis. However, to avoid resistance from occurring, the use of antibiotics for infection prevention should remain exceptional.

The use of a non-toxic antiseptic might be a better alternative. Recently, the use of an alcohol lock solution was suggested as a promising way to prevent CRBSI and the compatibility of polyurethane and silicone catheters submerged in an alcohol solution was publicized with no biomechanical or structural changes detected after 9 weeks of immersion. The major advantage of an alcohol lock solution would be the broad antimicrobial spectrum without the risk of compromising future antibiotic treatment as, in contrast to the use of an antibiotic lock, the development of antibiotic resistance is not of concern. Furthermore it would be cheap and universally available.

In this randomised study, the efficacy of a 70% alcohol lock solution for the prevention of CRBSI will be compared with placebo when applied for 15 minutes per day.
