Objective: To study in vitro the micro-organism absorption properties of a hydrogel wound dressing, TenderWet.
Method: Microbial films on agar plates and suspensions with common wound bacteria (Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa) and a fungal strain (Candida albicans) were studied.
Results: The hydrogel dressing reduced the number of micro-organisms significantly, both on the agar plate and in suspension. The in vitro data show that the hydrogel dressing absorbed the micro-organisms from the environment. Electron microscopic imaging clearly demonstrated that the germs were attached to the surface of the dressing’s superabsorbent polymer core.
Conclusion: In vitro data show that the hydrogel dressing TenderWet attracts and retains micro-organisms and reduces the number of viable germs. Clinical experience underlines this fast cleansing and debriding effect of the hydrogel wound dressing.
Declaration of interest: This study was supported by IVF HARTMANN AG, Neuhausen, Switzerland.
