Brief Summary:
The study investigates the efficacy of a catheter with antibacterial surface coating in preventing central venous catheter related infection and the effect of an intensive hygiene and catheter care education of the nursing staff on preventing central venous catheter-related infection.

Condition or disease Intervention/treatment Phase
Renal Insufficiency Device: GamCath® central venous catheter Device: GamCath Dolphin® Protect central venous catheter Not Applicable

Detailed Description:

The risk of catheter-related bloodstream infection depends on catheter type, method and site of insertion, aseptic technique and number of manipulations. To address this problem, efforts have focused on engineering biomaterials and surfaces with antibacterial properties to prevent bacteria adhesion and biofilm formation.

In view of the necessity to reduce catheter-related bloodstream infections and of the inadequacy of currently available antimicrobially coated devices, a new antimicrobial catheter surface was developed.

Among other factors, the mode and quality of catheter handling and care of exit site is an important aspect with respect to catheter-related infections.

The clinical study aims at providing data on antimicrobial efficiency of the 2 types of CE certified double lumen catheters and a supposed additional preventive effect of intense hygiene training on catheter-related infections.
