This is actually wonderful news
and it means that we can bridge damaged flesh in such a way as to encourage
full healing.
Third degree burns usually have
loss of flesh besides the skin itself. Cleaning
and replacing the removed flesh is obvious called for and using this to act as filler
is ideal. Other protocols have been introduced
and it can now be said that the most severe damage can now be effectively
repaired.
Plastic surgery will have a heyday
with this also as we can now remove scar tissue directly and remodel flesh to replace
that lost.
The apparent intractable problems
associate with severe burns are on the verge of been remedied.
Cotton candy-like material used to heal difficult wounds

DermaFuse, a glass nanofiber material that looks like cotton candy, has
been shown to speed healing in difficult-to-treat wounds
Many diabetics suffer from a condition known as venous stasis, which
can result in wounds on their extremities that remain unhealed for up to
several years – if infection sets in, amputation of the limb is sometimes even
necessary. Such wounds can sometimes be treated with vacuum-assisted systems,
but the equipment required is expensive, and must be carried by the patient
at all times. In clinical trials conducted last year, however, human venous
stasis wounds were quickly and thoroughly healed with an inexpensive new glass
nanofiber material, that looks like cotton candy.
Known as "DermaFuse," the material is made from borate glass
by the Mo-Sci Corporation in Rolla ,
Missouri . Similar
"bioglass" materials do already exist, but they are made from silica
and are used in the regeneration of hard tissues, such as bone. Boron has been
shown to react to body fluids considerably faster than silica, and to be
effective against harmful bacteria, which is why Mo-Sci chose to use it in
DermaFuse.
The material is designed to mimic the microstructure of fibrin, which
is one of the main components of blood clots. Like fibrin, the glass fibers
trap blood platelets, and provide a scaffolding for the wound covering to form
across. DermaFuse is also rich in calcium, which has been shown to speed
healing by assisting the migration of epidermal cells to the wound site.
As the wound heals, the fibers are absorbed by the patient's body –
little if any scarring results, and no bandages or sutures need to be removed.
After initial animal trials, DermaFuse was tried out on a group of 12
human venous stasis patients in 2010. Venous stasis is caused by poor blood
circulation in the extremities, which results in fluid pooling in those areas
(especially the lower legs) and creating pressure on the skin. When the skin
cracks or receives a small wound and the fluid weeps out, an enzyme within the
fluid erodes the skin and makes the wound larger, while also making healing
difficult.
In the human trials, a nurse packed the material into the patients'
wounds, then added a protective secondary covering. After a few months, the
wounds on eight of the patients were fully healed, while the other four were
reportedly progressing well.
Mo-Sci is now
planning on expanded human trials in the coming months. It is hoped that
DermaFuse could eventually also be used to treat injuries such as burns, or
used as a field dressing by ambulance crews and army medics.
The research was just published in the bulletin of The American Ceramic Society.
