CH 33/55 Skin Integrity and wound care Flashcards
Wounds are the results of
injury to the skin
Although there are many different methods and degrees of wound injury
the basic phases of healing are essentially the same for most wounds
A pressure injury is
a specific type of tissue injury from unrelieved pressure usually over bony prominences that results in ischemia and damage to the underlying tissue
stages of wound heal thing
Inflammatory stage, proliferative stage, maturation or remodeling stage
Inflammatory stage(1)
Begins with injury and last 3 to 6 days
Proliferative Stage(2)
last 3-24 days replacing lost tissues resurfacing new epithelial cells
Maturation or remodeling stage (3)
occurs on about day 21 and involves the strengthening of the collage scar it can take more than 1 year to complete
Primary Intention
little to no tissue loss, edges approximated with surgical incision. heals rapidly, low infection risk, minimal scarring
Example of primary intention
closed surgical incision with staples. sutures, or liquid glue
Secondary intention
loss of tissue, wound edges separated, longer healing, increase infection risk, scarring, heals by granualation
Secondary intention example
pressure injury left open to heal
Tertiary intention
widely separated, deep, risk of infection, closed later,
Tertiary Intention example
abdominal wound initially left open until infection is resolved and then closes
Factos affecting wound healing
age, overall wellness, decrease leukocyte count, infection, meds such as anti-inflammatory and antineoplastic. malnourshed clients, tissue perfusion, low hgb levels, obesity, chronic diseases, smoking, wound stress
Note the appearance of
open wounds
red wound
healthy regeneration of tissuey
yellow wound
present of purulent drainage and slough
black wound
present of eschar that hinders healing and requires removal
USE RYB color code guide for wound care
red-cover
yellow-clean
black-deride, remove necrotic tissue
closed wounds
skin edges should be well approximated
drainage
aka exudate
drainage (exudate)
A result of the healing process and accumales during the inflammatory and proliferative phases
Note the amount, color, consistency of wound
drainage
For an accurate measurement of drainage weigh the dressing
1g=1ml of drainage
