Abstract:

OBJECTIVE: The present study aims to assess if use of a silver zeolite-impregnated umbilical catheter (AgION technology) can decrease the occurrence of catheter-related bloodstream infection (CRBSIs) in preterm infants.

STUDY DESIGN: Infants with gestational age<30weeks were randomized to receive an AgION impregnated or non-impregnated polyurethane umbilical venous catheter (UVC). The primary endpoint was the incidence of CRBSIs during the time the UVC was in place.

RESULTS: We studied 86 infants, 41 of whom received the AgION catheter and 45 the non-impregnated catheter. During umbilical venous catheterization 2% of infants in the AgION group developed CRBSI in comparison with 22% of infants in the control group (p=0.005). AgION catheters were well tolerated and none of the patients showed signs attributable to silver toxicity.

CONCLUSIONS: The AgION-impregnated UVCs were effective in decreasing the development of CRBSIs in preterm infants compared to non-impregnated polyurethane UVCs.
