Epithelialization d. Eschar e. Granulation tissue f. Induration g. Maceration h. Necrosis
(necrotic) i. Sinus tract (related to wounds) j. Slough k. Undermining ✅a. Collagen
Tissue: The most abundant protein in the human body
Found in bones, muscles, skin and tendons
Scaffolding that provides strength, structure and holds the body together.
Two types: Endogenous and Exogenous
Act as protective coverings for delicate organs in the body, such as kidneys.
In the dermis, middle layer of skin, collagen helps form fibroblast.
Helps replace and restore dead skin cells
Medical
Originates from humans, cows, pigs or sheep
Wound dressings
Guided tissue regeneration
Vascular prosthetics
Cosmetic
Collagen injections/fillers
b. debridement:
Surgical
Mechanical
Chemical
Autolytic
Maggot
c. epithelialization: Process where the skin and mucus membranes replace superficial
epithelial cells damaged or lost in a wound.
The edge of the wound proliferate immediately after injury to cover the denuded area.
d. eschar: Dead tissue that sheds or falls off from the skin.
Commonly see with pressure ulcer wounds
Typically tan, brown or black
e. granulation tissue: New connective tissue and microscopic blood vessels that form on
the surface of a wound during the healing process.
Red, moist tissue composed of new blood vessels which indicated progression toward
healing
Typically grows from the base of a wound.
f. induration: Abnormal firmness or hardness of tissue with margins as a result of edema
or inflammation.
g. maceration: The softening and breaking down of skin resulting from prolonged
exposure to moisture.
Leaving a bandage on while washing dishes
,h. necrosis: A form of cell injury that results in premature death of cells in living tissue by
autolysis.
Caused by factors external to the cell or tissue
Toxins, infection or trauma
Results in unregulated digestion of cell components
i. Also referred to as "tunneling wounds"
A narrow opening or passageway extending from a wound underneath the skin in any
List and describe the three phases of wound healing for full-thickness wound repair.
✅inflammatory-destroys bacteria, removing debri
4-6 days
fibroblastic(proliferation)-filling wound, wound gets smaller, epithelialization
4-24 days
maturation(remodeling)-new tissue gets strength, collagen, new skin 80% as strong
21 days-2 years
Describe the role of nutrition in wound healing and essential nutrients required for the
wound healing process. ✅Nutrition is very important factor during the healing process.
Poor nutrition can delay healing and impair wound strength making the wound more
prone to breakdown.
Macronutrients-carbs proteins and fats
Micronutrients-vitamins & minerals
Describe the three systemic reactions to inflammation in wound healing nursing
interventions indicated with these systemic reactions. ✅Systemic inflammatory
response syndrome (SIRS) is an exagerrated defense response to the body to a
noxious stressor.
Sepsis-2 or more inflammatory responses + unknown or suspected infection
Severe Sepsis-Acute organ dysfunction + sepsis criteria
Septic Shock-form of severe sepsis
Describe the principles most important in the management of open wounds and topical
agents prescribed for an open wound. ✅Ongoing treatment of a wound.
Providing appropriate environment for healing
Direct and indirect methods
Stop bleeding
Clean wound
Treat with antibiotics and medications
Close and dress the wound
, Routinely change the dressing
Describe the specific areas of wound assessment. ✅Location
Size
Stage
Drainage
Undermining/Tunneling
Character of wound
Dressings
Pressure Relieving devices
Compare and contrast the different types of wound dressings and one product for each
type of dressing, indication for use, and nursing implications for each type of dressing.
✅Hydrocolloid
Used on burns, wounds emitting liquid, necrotic wounds, pressure ulcer and venous
ulcers.
Non-breathable, self-adhesive and require no taping
Suitable for sensitive skin
impermeable to bacteria
Hydrogel
Used for leaky and non-leaky wounds that are painful or necrotic.
Used on pressure ulcer or donor sites
Second-degree burns and infected wounds
The cooling effects of the gel reduce pain and speed up healing
little or no leaking
Aliginate
Used for high drainage wounds, burns and ulcers.
Absorbs excess liquid and creates a gel that helps healing
Contains sodium and seaweed fibers
Change every 48 hours
biodegradable
ex: open heart surgery
Collagen
Used for chronic wounds or stalled wounds, pressure ulcers, transplant sites, surgical
wound and burns over large areas.
Helps grow new cells and promotes healing
highly effective
Foam
Perfect for malordorous wounds
Absorbs exudate
Keeps the wound area moist, promoting faster healing.
Adhesive and non-adhesive options
