1 Introduction
Abrasion (medical)

Wikipedia

 

In dermatology, an abrasion is a wound caused by superficial damage to the skin, no deeper than the epidermis . It is less severe than a laceration, and bleeding, if present, is minimal. Mild abrasions, also known as grazes or scrapes , do not scar or bleed, but deep abrasions may lead to the formation of scar tissue. A more traumatic abrasion that removes all layers of skin is called an avulsion .

Abrasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis.




  • A first-degree abrasion involves only epidermal injury.

  • A second-degree abrasion involves the epidermis as well as the dermis

and may bleed slightly.

  • A third-degree abrasion involves damage to the subcutaneous layer and the skin

and is often called an avulsion.




The abrasion should be cleaned and any debris removed. A topical antibiotic (such as Neosporin or bacitracin) should be applied to prevent infection and to keep the wound moist. If the abrasion is painful, a topical analgesic (such as lidocaine or benzocaine) can be applied, but for large abrasions a systemic analgesic may be necessary.
