Bloodstream infections are common in Intensive Care Units (ICUs). The need of a central venous line increases the risk of bacteremia and central venous catheter (CVC) related infections. The use of catheters coated and/or impregnated with different antimicrobial agents has been proposed to reduce the risk of such infections. However, results obtained so far did not reach enough clinical relevance to consider these medicated catheters as a valid alternative to the conventional ones.

The aim of this comparative randomized study is to assess the ability of recently developed silver ion-releasing central venous catheters in preventing associated infections in comparison with the conventional ones.

Experimental groups are defined as follows:

  • Group A: patients treated with standard, triple lumen, non medicated catheters
  • Group B: patients treated with triple lumen catheters impregnated with silver nanoparticles

Condition Intervention Phase
Central Venous Catheter Related Infections
Procedure: CVC impregnated with silver nanoparticles (AgTive®)
Procedure: CVC cannulation
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: A Parallel, Randomized Multicenter Comparison of Triple Lumen Central Venous Catheters Impregnated With Silver Nanoparticles (AgTive®) Versus Conventional Catheters in Intensive Care Unit Patients

Further study details as provided by Catholic University of the Sacred Heart:

Primary Outcome Measures:
  • The primary end-point is the difference in raw percentage occurrence of central venous catheter related infections (CVCRI) (on a patient basis) between groups A and B. [ Time Frame: period during the ICU stay ]

Secondary Outcome Measures:
  • The secondary end-point are the infection-free time and the probability of CVCRI as a function of multiple predictors. [ Time Frame: period during the ICU stay ]

Estimated Enrollment: 472
Study Start Date: July 2006
Study Completion Date: September 2008
