Wounds

how many phases of wound healing are there?

3

what are the 3 phases of wound healing?

inflammatory, proliferate and remodeling

inflammatory, proliferate and remodeling are what?

the 3 phases of wound healing

what is phase 1 of wound healing

inflammaory

how long does inflammaory phase of wound healing last?

0-6 days

what is phase 2 of wound healing?

proliferate

how long does proliferate phase of wound healing last

4-21 days

what is phase 3 of wound healing

remodeling

how long does remodeling phase of wound healing last?

21 days- 2 years

what does inflammatory phase (phase 1) of wound healing include?

hemostasis and phagocytosis

hemostasis

the stopping of a flow of blood.

phagocytosis

The process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria) and removes dead cells.

what is a pressure wound?

The process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria) and removes dead cells.

how many stages of pressure wounds are there?

4 (5-unstageable)

what are the 4 (5) stages of pressure wounds?

1. non-blanchable redness: epidermis

2. partial thickness skin loss; epidermis and dermis stage

3. full thickness loss to subcutaneous tissue

4. full thickness loss through fascia: may reach bones or connective tissue

5. unstageable: unable to determine due to tissue or blister obscuring the wound

what is stage 1 of pressure wounds/

non blanchable redness: epidermis

what is stage 2 of pressure wounds?

partial thickness skin loss; epidermis and dermis

what is stage 3 of pressure wounds?

full thickness loss to subcutaneous tissue

what is stage 4 of pressure wounds?

full thickness loss through fascia: may reach bones or connective tissue

what is stage (kinda) 5 of pressure wounds?

unstageable: unable to determine due to tissue or blister obscuring the wound

colors of wounds include:

black, yellow and red

black wound

sign of necrosis

necrosis

the death of body tissue

how to treat black wound

debride it

debride

remove damaged tissue or foreign objects from (a wound).

yellow wound

sign of infection

how to treat yellow wound

clean it

red wound

bleeding/inflammation

how to treat red wound

protect it

how to treat wound with exudate

soak it

exudate

a mass of cells and fluid that has seeped out of blood vessels or an organ, especially in inflammation.

how to treat dry wound

moisten it

angiogenesis

part of proliferate stage of wound healing where there is a formation of new blood vessels

what happens in hemostasis

platelets release grow factors (fibrin) that stop the bleeding and start the repair process at the wound location
