Yannas and Bruke
“Pioneers of Artificial Skin”
Complex of collagen and condroiton sulphuric acid with silicon membrane
How it Works
Artificial skin is secured over wound during surgery
The skin remains in place for several weeks and allows new tissue to grow in to bottom matrix layer
Top layer provides protection from infection and dehydration
Benefits
Protect skin from infection
Keep in moisture to prevent dehydration
Encourage healing through construction of new tissue by infiltration of epidermal cells and fibroblasts
Allow for less severe scarring
More readily available
Improvements
Biodegradable skin
Doesn’t need to be removed
Slowly releasing antibiotic
Prevents infection
Re freeze dried artificial skin
Easier storage and reconstitution
Addition of epithelial growth factor and basic fibroblast growth factor
Increased regeneration of tissue
