Ch 30 Plastics and Reconstructive Surgery Review 1. What are the three classifications of burns? . First-degree burn Second-degree burn Third-degree burn. What are the characteristics of a First-Degree Burn?.
E N D
First-degree burn • Second-degree burn • Third-degree burn
A burn that involves the epidermis only (e.g., sunburn); it is referred to as a partial-thickness burn. This type of burn heals within a few days without treatment. • What are the characteristics of a Second-Degree Burn?
Damage occurs to both the epidermis and the dermis; this also is referred to as a partial-thickness burn. It heals within a few weeks with topical treatment. • What are the characteristics of a Third-Degree Burn?
This may be an electrical, chemical, or thermal burn. It results in permanent damage to the skin and underlying tissues; it is referred to as a full-thickness burn. These burns require debridement and skin grafting to maintain skin integrity. • When is debridement necessary for the treatment of burns?
For diseased or traumatized tissue to heal, all devitalized or infected areas must be removed. Damaged or dead cells prevent the formation of fibrin, collagen, and other matrix tissue that binds the healing tissues. The process of removing the diseased, damaged, or infected tissue is called debridement. • What is compartment syndrome?
Severe swelling and tissue injury caused by constriction of the blood and lymph. Compartment syndrome can progress to tissue necrosis. • Differentiate between a full-thickness and split-thickness skin grafts.
Composed of the epidermis and dermis. A split-thickness skin graft consists of the epidermis and a portion of the papillary dermis. • Explain the purpose of a flap graft.
A pedicle, or flap, graft provides coverage and vascularization to a soft tissue defect. • What is a biosynthetic material?
Biosynthetic material is absorbed by the body or enhances healing but is not derived from biological tissue. • The two layers of the skin are the epidermis and the _____________
Dermis • The hair muscle _____________ is responsible for producing "goose bumps."
arrectorpili • Is tissue or wound debridement a contaminated/sterile procedure?
contaminated • A scar consisting of dense tissue is called a _____________
keloid • Before using the dermatome _____________is applied to the graft site.
mineral oil • ____________are grafts that were harvested from donors and preserved by the tissue bank until needed.
allografts • Third-degree burns develop _________,which is devitalized, nonelastic tissue adhering to the wound site.
Eschar • A graft derived from live tissue—human or animal—is called a(n) __________________.
