Fundies. ch.27 and ch.38 Flashcards
2 types of wounds
open or closed
closed wound
Contusion (bruise), Hematoma, and Sprain
open wound
Incision, Laceration, Abrasion, Puncture, Penetrating, Avulsion, and Ulceration
Heal more quickly by producing new skin cells and Fibrin clot forms framework for growing new cells. What kind of wound is this?
Partial-thickness wounds
No dermal layer present except at margins of
wounds and All necrotic tissue must be removed
(heals by contraction) What kind of wound is this?
Full-thickness wounds
what are the three
distinct phases of wound healing?
Inflammatory phase, Proliferation or reconstruction phase, and Maturation or remodeling phase
what phase Begins immediately and lasts 1 to 4 days
Inflammation Phase
what phase Begins on third or fourth day; lasts 2 to 3 weeks?
Proliferation Stage of Wound Healing
Final phase begins about 3 weeks after injury
May take up to 2 years
Maturation Phase of Wound Healing
Factors that Affect Wound Healing
age, peripheral vascular disease, decreased immune system function, reduced liver function, and decreased lung function
Decreased BP; increased pulse rate; increased
respirations; restlessness; diaphoresis; cold, clammy
skin (hypovolemic shock may occur)
hemorrhage
an abscess, or an accumulation
of pus from debris as a result of phagocytosis
infection
Inflammation of tissue surrounding the wound,
characterized by redness and induration
cellulitis
An abnormal passage between two organs or an
internal organ and the body surface
Fistula
A canal or passageway leading to an abscess
Sinus
a sign may be increased
flow of serosanguineous drainage
Dehiscence. The spontaneous opening of an incision
Protrusion of an internal organ through an incision
Evisceration
Clean and ready to heal; protective dressing
should be used
Red wounds
Have a layer of yellow fibrous debris and
sloughing; need to be continually cleansed and
have an absorbent dressing
Yellow wounds
Need débridement of dead tissue, usually caused
by thermal injury or gangrene
Black wounds
Protective coverings placed over wounds
Dressings
Débridement
Removing necrotic tissue from a wound so
that healing can occur
