The majority of infected wounds are highly exuding, creating a favourable environment for biofilms

Conventional foam dressings leave a gap between the wound bed and dressing, allowing exudate to pool. This may promote bacterial growth leading to increased risk of infection and subsequent development of biofilms.

Biofilms are clusters of bacteria and fungi embedded in the wound environment, which can form within 24 hours. Biofilms are difficult for the immune system and antibiotics to eradicate2.
New research shows that biofilms can be found both in the wound bed surface and in the tissue below the wound bed3. Its presence can lead to infection, inflammation and delayed healing4.

Promoting optimal healing conditions for infected wounds

1. Wound bed preparation

Cleansing and debridement of infected wounds
removes slough and non-viable tissue, including some biofilms, prior to the application of a dressing.

2. A conforming dressing

The dressing should fill the gap between the wound bed
and dressing, as well as absorb and retain exudate,
thereby creating a less favourable environment
for biofilm development.

3. Infection management

The active component should be effective against biofilms and a broad range of bacteria and fungi to support optimal healing conditions.

Combat infection and biofilms where it matters

Kill 99.99% of mature biofilms

Biatain Silicone Ag has been shown to kill 99.99% of mature biofilms (P. aeruginosa) and to prevent biofilm formation (shown in vitro).1 Biatain Silicone Ag is also effective against a broad spectrum of bacteria and fungi for up to 7 days.1

Conform to the wound bed

Biatain Silicone Ag conforms to the wound bed to reduce exudate pooling and deliver Ag at the wound bed.

Absorb vertically

The microcapillaries within the foam absorb exudate vertically, triggering the release of Ag.

Retain exudate

Exudate is locked away and retained even under compression, reducing the risk of maceration and spreading of infection to the wound edges and periwound skin.

Complete healing of an infected diabetic foot ulcer after 6 weeks treatment with Biatain Silicone Ag

The patient was an 80-year-old man with type 2 diabetes mellitus for 20 years. The ulcer was infected with S. aureus and Corynebacterium. Duration of the ulcer was 8 weeks prior to treatment with Biatain Silicone Ag.
