Blisters, Abrasions, and Skin Tears
| back to skin disease index
Blisters
Blisters form as a result of heat, moisture and
friction. Blisters can also form as a result of fungal
infections of the skin, allergic reactions or burns. If
a patient has diabetes, they should be evaluated by a
doctor in a timely fashion. Generally, a person will
recognize a burn by association with a specific painful
event. People with diabetes may not be able recognize
the painful event due to a condition called neuropathy.
A doctor should attend to burns. Blisters are due to
fungal infection of the skin or to allergic reactions,
which will generally occur in clusters and be smaller
than blisters caused by friction. They will also often
occur in areas of the foot, which are free from friction
forces.
Blisters should be drained leaving the cover of the
blister in tact. The area should be protected with a
non-stick bandage with mild compression. Ice to "hot
spots" can be soothing and reduce the thermal damage to
the surrounding area. "Double socking" can prevent
blisters associated with athletics. Wearing two pair of
socks allows the friction to be absorbed between the
socks reducing friction to the skin. A sock has been
developed that helps to reduce friction and blistering
called the Thro-lo sock. It is useful for athletics and
for diabetic patients. They are widely available in
athletic shoe and apparel stores. Skin protectant sprays
and adhesive gel pads are also available.
Abrasions
Abrasions to the skin are a result of excessive friction
resulting in the partial loss of the epidermis. The area
should be cleaned with an antibacterial soap and dressed
with a non-stick bandage and a topical antibiotic
ointment. It may take several weeks for the area to
completely heal. During this period, the area should be
protected from shearing forces. Deep abrasions can
result in scaring. Any sign of infection should prompt a
visit to the doctor.
Skin Tears
Skin
Tears result from a rapid, forceful shear to the skin.
Skin tears are most commonly self inflicted by
improperly removing adhesive dressings and tape. Careful
counter pressure should be applied to the skin near the
adhesive dressing as the dressing or tape is slowly
removed. A common misconception is that paper tape will
not damage the skin. To the contrary this tape can
really stick to the skin and will tear the skin if
removed improperly. |
