1
Intrinsic factors of wound healing
-age
-chronic diseases present
-perfusion/oxygenation
-immunosuppresison
-neurologically impaired skin
2
Extrinsic factors of wound healing
-medications
-nutrition
-irradiation and chemo
-psych stressors
-wound 'bioburden" and infection
3
Bioburden
-Whatever is colonized on a wound
-pathogens
4
Iatrogenic Factors for healing
-local ischemia due to pressure/other forces
-inappropriate wound care
-trauma
-wound extent and duration
5
Zones of Wound Healing
-zone of hyperemia
-zone of stasis
-zone of coagulation
6
Zone of coagulation
-area of necrosis
-will not heal
7
Zone of Hyperemia
-inflammatory response surrounding the wound
-normal tissue going through normal response
-redness of skin
8
Zone of Stasis
-part that may or may not heal
-important to protect this zone so it can heal
-hanging in the balance
9
Re-epithelialization
-recreation of a permeable barrier
-skin reinstituted as functional barrier
-epithelial cell migration from nearby tissues begins within hours of injury
10
Granulation Tissue
-new or budding tissue
-composed of capillaries and collagen
-fills defects of full-thickness wounds
-bleeds easily, relatively fragile
11
Demarcation
-clear differentiation between viable and non-viable tissue
12
Excoriated Tissue
-epidermal tissue abrasion
-to chafe, tear or wear off the skin
-often linear
13
Sinus Tract
-channel or passageway extending into viable tissues with one entrance only
-travels under skin
14
Tunneling
-narrow channel or passageway with openings on both ends
15
Abscess
-localized collection of pus
16
Induration
-palpably hard tissue
-often at edge of wound
-can indicate abscesses (must determine cause)
17
Drainage
-Exudate or transudate
-indicates inflammatory response
18
Exudate
-found in inflammatory stage of wound healing
-contains cells, proteins and other solid materials
-2 kinds: purulent or serous
19
Purulent
-milky/cloudy appearance but can be any color
-indicate infection
20
Serous
-thin, clear usually amber color
-mostly contains serum
-(Serosanguinous-thin with some RBC)
21
Transudate
-thin, cloudy drainage found in the proliferation stage of wound healing
-like exudate but has fewer cellular componenets
22
Dehiscence
-splitting of open wound
-separation of layers of surgical wound (partial, superficial or complete)
-bad
23
Risk Factor of Dehiscence
-obesity
-because adipose is less vascularized
24
Necrosis
-tissue death
-residual dead tissue can impede normal healing
25
Slough
-Yellow and thin covering of wound
-stringy appearance
26
Eschar
-more advanced necrosis
-soft or hard (leathery)
-represents full-thickness destruction of tissue
-black/dark colored
27
Necrotic tissue tends to become more______
-adherent to wound bed as level of damage increases
28
As necrotic tissue worsens, the color may____
-progress from white-grey to yellow to brown/black
29
Methods of Wound Closure
-first intent
-secondary intent
-third intent
