Wound deck II Flashcards
Granulation tissue
New connective tissue and tiny vessels that form on the surface of wounds during the early healing process
Epithelialization
Epithelium is a membranous tissue made up of one or more layers of cells that contains very little intercellular substance. The process of epithelialization is the closing or sealing of a wound.
Necrosis
Death of tissue usually from lack of blood supply
Eschar
A dry tough scab or slough. Often seen with burns or cauterization of the skin.
Exudate
A fluid that has moved out of tissue or its capillaries due to injury or inflammation
Dehiscence
A surgical complication where the edges of a wound no longer meet. It is also known as wound separation. There may be drainage noted.
Serous drainage
Clear, thin, watery plasma. Its normal during the inflammatory stage of wound healing
Sanguineous exudate
Fresh bleeding, seen in deep partial thickness and full thickness wounds. A small amount may be normal during the inflammatory stage.
Serosanguineous exudate
Thin, watery, and pale red to pink in color. The pink tinge, which comes from red blood cells, indicates damage to the capillaries with dressing changes.
Seropurulent exudate
Thin, watery cloudy, and yellow to tan in color
Purulent exudate
Thick and opaque. It can be tan, yellow, green, or brown in color. its never normal in a wound bed. BAD
phagocytosis
the process of white blood cells that ingest smaller cells or cell fragments
Slough:
the layer of dead tissue that separates tissue from sound flesh
Angiogenesis
The growth of blood vessels to increase or return circulation to a healing tissue (1mm a day)
Red wound
uninfected, granulation tissue, revascularization
Yellow wound
Drainage, slough, delayed epithelization
Black wound
Eschar, necrotic tissue
Debridement
Manual removal of dead tissue, eschar, slough, and fibrin
Sharp debridement- scissors, scalpel
tweezers
chemical debridement
surgical debridement
ways to classify wounds
open or closed
acute or chronic (new or old wound)
Partial thickness or full thickness
acute wounds
abrasions (scrapes, road rash, laceration or incision- knofe, glaze, razor,
Avulsion- body structure is pulled or detached
Animal bites
Traumatic injuries- MVAs
closed wounds-
contusions, crush injuries, sprains
chronic wounds
- wounds that fall outside the 3 phases of wound healing due to complications or severity
- Treatment is based on treating the underlying pathological condition
- Chronic wound can be converted to an acute wound with debridement
- Chronic wounds do not proceed through and orderly timely repair process.
Primary dressing
the dressing that goes directly on top or inside of the wound
Secondary dressing
Usually used to secure the primary dressing such as gauze, tegaderm, coban.
Decubitus Ulcers
Also known as pressure ulcers, pressure sores, and bed sores
