Polymer-impregnated dressing successfully fights infection
Researchers in the US have found that dressings impregnated with an antibacterial polymer can fight infection in wound healing, reducing bacteria by 99.9% in three days.
Infection can block the healing of over 20% of patients with wounds. This new dressing has a small amount of chlorhexidine impregnated within the dressing, which effectively fights infection. The use of chlorhexadine has been used in the past, but topically and in high concentrations, which has been known to cause skin damage and can do more harm than good.
If infection can be prevented in the first few days, especially in patients being treated for burns and chronic ulcers, then skin substitutes are more likely to effectively cover the wound and promote proper healing.
'Our goal was to reduce the amount of antibacterial agent needed, so it's not toxic to the healing cells, just to bacteria, and to reduce the need to reapply the solution,' said Ankit Agarwal, post-doctoral researcher at University of Wisconsin Madison. 'By incorporating this nanofilm on the wound-contact surface of the skin substitute, we provide a sustainable and prolonged localised release of the antiseptic on the wound.'
