An abrasion wound is an open wound wherein the surface layer of skin is scraped or grazed off at the injury site. Abrasions are a highly common type of injury that can range from mild to severe and commonly occur on the ankles, elbows, knees, shins, or upper extremities, including the upper arm, forearm, or hand. In contrast with cuts and lacerations, abrasions do not typically involve heavy bleeding. With that being said, they sometimes involve minor bleeding and often ooze pinkish fluid. Moreover, severe abrasions and abrasions affecting the face or head will involve much more significant bleeding. Abrasions are classified in degrees according to the severity of the injury. With that in mind, a first-degree abrasion occurs with only superficial damage to the epidermis, or surface layer of skin, without any bleeding. Second-degree abrasions involve damage to the epidermis and the dermis, or the layer of skin directly beneath the epidermis, and involve minor bleeding. Finally, third-degree abrasions are known as avulsions, wherein there is friction and tearing of the dermis layer of skin, causing heavy bleeding and requiring immediate medical care.
