Introduction: Colonization of central venous catheters (CVC)s by microorganisms is an event that precedes central line associated bloodstream infection (CLABSI). It is plausible that sealing the skin insertion site of CVCs with 2-octyl cyanoacrylate adhesive may reduce catheter colonization by creating a sterile barrier and minimizing subsequent extraluminal colonization of the catheter. We explored this by evaluating the ability of the skin adhesive to maintain a sealed interface by visual inspection.
Materials and Methods:19 enrolled patients underwent application of 2-octyl cyanoacrylate adhesive to the CVC insertion site, followed by daily inspection for visual signs of 2-octyl cyanoacrylate loss of seal integrity with the skin/catheter interface. Additionally, patients were monitored daily for local cutaneous reactions and/or catheter malfunction. After the clinical team removed the catheter, the tip was sent to the microbiology lab for culture via roll plate method.Results: Seal integrity by visual inspection was maintained for a range of 24 days (1-25 days), mean of 6.9 days a median of 7.0 days, and a mode of 7 days. Among the 4 catheters that were cultured in the microbiology laboratory one demonstrated bacterial colonization.Conclusion: 2-octyl cyanoacrylate sealed the skin/catheter insertion site for about 7 days, by visual inspection. Further investigation is necessary to determine if use of this skin adhesive leads to reductions in the rate of catheter colonization and CLABSI.
