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

30

First Intent Closure

-close the wound and done
