Abstract

<p>It is clear that bacterial flora of skin around the catheter insertion site would be associated with catheter related bloodstream infection (CRBSI). We evaluated the antibacterial effect of film dressings including Fixkit®・CV (ALCARE Co., Ltd. Tokyo, Japan), which was composed of a transparent film adhesion material and an antibacterial pad with zinc, for skin around the catheter insertion site. We compared the antibacterial film dressing Fixkit®・CV and non-zinc contained film dressing as randomized control trial in the Aichi Medical University Hospital. The protocol was reviewed and approved by a local institutional committee, and written informed consents were obtained before enrolling. Two hundred and two patients with central venous catheter were enrolled in this study; 102 for Fixkit®・CV and 100 for non-antibacterial film dressing. We performed a quantitative microbial examination for a skin area of 1 cm2 around the catheter insertion site after removing the dressing films. The rates of positive bacterial detection for Fixkit®・CV and non-antibacterial film dressing were 47.1% and 62.0%, respectively (p= 0.03). According to logistic regression analysis, body mass index (BMI), gender, and insertion site of central venous catheter (CVC) were significant factors to isolate bacteria from the skin around the catheter insertion site. Positive bacterial detection rates between patients with BMI >25 and <25 were 73.8% and 49.4%, respectively (p = 0.01). BMI was the most important factor for the number of bacteria of skin around the catheter insertion site. We conclude that antimicrobial dressings such as antibacterial pad with zinc would be able to decrease the risk of skin colonization around the catheter insertion site in patients with BMI<25.</p>
