E-POSTER PRESENTATIONS EP 480 E-Poster: Dressings COMPARISON OF PASSIVE BACTERIA ELIMINATION VERSUS ACTIVE BACTERICIDAL EFFICACY IN A QUANTITATIVE IN-VITRO AGAR DIFFUSION ASSAY Florian H. H. Brill 1 , Horst Braunwarth 2 1 GmbH Institut for Hygiene and Microbiology (Hamburg, Germany); 2 Coloplast GmbH (Hamburg, Germany). Aim: Bacterial burden may delay or stop the wound healing process. For reduction of bacterial burden different methods are applied. Recently, passive methods based on hydrophobic interactions were presented where bacteria adhere to the wound dressing (bacteria elimination). The aim of this in-vitro-study was to compare the capacity of bacteria reduction with passive elimination versus active killing. Methods: The antimicrobial efficacy of the test products was measured in an agar diffusion assay as well as with a quantitative test method. In this method the active agents were inactivated after the contact time and log10 reduction factor (RF) in relation to the control dressing have been determined (10 parallels). Contact time: 24 h Test bacteria: Staphylococcus aureus, Pseudomonas aeruginosa Test products (active principle): Polyurethane Foam Dressing 1 (passive elimination) Hydrophobic Dressing 2 (hydrophobic elimination) Silicone Dressing 3 (hydrophobic elimination) Hydrocapillary Dressing 4 (passive elimination) Silver Polyurethane Foam Dressing 5 (active kill). Gaze with Water (control) Results: The hydrophobic dressing 2 was not able to reduce the bacterial burden. All other passive methods were able to reduce the bacteria burden (RF 0.4 – 2.1). The active killing method with silver ions was superior (RF 6.8 – 8.7) (figure 1). Conclusion: Our data show that also passive elimination of bacteria from wounds e.g. with polyurethane foam dressings may lead to a significant reduction. However, the antibacterial efficacy of a silver foam dressing is superior compared to passive elimination. 1 Biatain Foam Dressing, 2 Cutimed Sorbact, 3 Cutimed Siltec, 4 Alione Hydrocapillary Dressing, 5 Biatain Ag Foam Dressing E-POSTER: DRESSINGS EP 481 E-Poster: Dressings COMPARISON OF HYDROPHOBIC CHARACTERISTICS FROM DIFFERENT WOUND DRESSINGS Horst Braunwarth 1 , Florian H. H. Brill 2 1 Coloplast GmbH (Hamburg, Germany); 2 Dr. Brill + Partner GmbH – Institute for Hygiene and Microbiology (Hamburg, Germany). Aim: Recently, wound dressings which claiming hydrophobic characteristics were presented. The hydrophobic effect should be responsible for irreversible binding of bacteria to the dressing. The aim of this in-vitro-study was to compare the hydrophobic characteristics of these with other wound dressings. Methods: Hydrophobic characteristics can be measured with the surface tension. The surface tension indicates how easy water can spread onto a solid material. To measure the surface tension, water drops were placed on test surfaces and contact angles were measured. A contact angle of 0° shows that a surface is hydrophilic; contact angels of around 90° indicate a hydrophobic surface. If significant higher angles are measured these surfaces are characterized as “super hydrophobic” and have the ability to show the famous “Lotus-effect”. Test surfaces (claim): Polyurethane Foam Dressing 1 (no hydrophobic) Polyurethane Foam Dressing Adhesive 2 (no hydrophobic) Hydrophobic Dressing 3 (hydrophobic) Soaking Hydrophobic Dressing 4 (hydrophobic) Hydroactive Hydrophobic Dressing5 (hydrophobic) Silicone Dressing 6 (hydrophobic) Silicone Dressing 7 (hydrophobic) Gaze with water (control) Results: The results show, that all test dressings regardless if they claim a hydrophobic characteristic have hydrophobic characteristics (figure 1 and 2). Conclusion: Our data show that polyurethane foam dressings as well as hydrophobic dressings have hydrophobic characteristics. It is expected that also other synthetic dressings which have not been tested show these characteristics. To our opinion, hydrophobic characteristics are no sufficient indicator for their clinical efficiency. 1 Biatain Foam Dressing, 2 Biatain Foam Dressing Adhesive, 3 Cutimed Sorbact, 4 Cutimed Sorbact Compress, 5 Cutimed Sorbact Hydroactive, 6 Cutimed Siltec L, 7 Cutimed Siltec 276
