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
