Chlorhexidine 2% and choice of transparent dressing increase skin reactions at central venous catheter insertion sites.

Infection at central venous catheter (CVC) sites remains a common problem, particularly with long-term use. This report discusses the influence of choice of transparent dressing type and chlorhexidine concentration on skin reactions at CVC insertion sites. A concentration of 2% chlorhexidine is associated with a higher rate of skin reactions than either 0.5% or 1% chlorhexidine. Higher chlorhexidine concentrations may not decrease the number of central line-associated bloodstream infections. (C) 2016 Association for Professionals in Infection Control and Epidemiology, Inc.
