Week 3 - Wound Classification Flashcards
1
Q
What is a wound?
A
- Any break in the skin can be classified as a wound.
- Our goal is to facilitate healing and prevent the risk of complications.
2
Q
Define a Primary Intention Wounds
(Intentional)
A
- Tissue surfaces have been approximated;
there is no or minimal tissue loss, includes: - Superficial Wounds
- Closed Surgical Incisions
- Wounds Joined by Adhesive ‘Glue’
- Healing Process is Predictable
- Healing Time 4 -14 days
- Minimal Scarring
3
Q
Define a Secondary Intention Wounds
(Unintentional)
A
- Greater tissue damage, loss
- Edges not easily approximated
- Delayed healing time
- Scarring
- More chance of complications such as infection
- Pressure injury, traumatic injury, burns, dehisced surgical wounds
4
Q
Define a Tertiary Intention Wounds
A
- Wounds that are left open for 3-5 days to allow fluids or infection to drain
- Are then closed with sutures, staples or adhesive skin closures
5
Q
What are the phases of wound healing?
A
- Haemostasis & Inflammatory phase
- Proliferative phase
- Maturation & Remodelling phase
6
Q
What is the Haemostasis & Inflammatory phase?
A
- Starts immediately after injury & lasts 3-6 days.
- Removes debris & prepares for new tissue:
o Haemostasis (cessation of bleeding)
o Blood supply increases (oxygen, nutrients, macrophages)
o Phagocytosis (engulf microorganisms & cellular debris)
7
Q
What are the clinical observation for Haemostasis & Inflammatory phase?
A
- Pain
- Redness
- Swelling
- Heat
- Exudate (clear)
- These descriptive terms are often used in documentation of wounds in progress notes.
8
Q
What is Proliferative phase?
A
- Second phase; from day 3 to day 21 post injury.
- Laying down of new cells, connective tissue:
o Fibroblasts synthesize collagen (adding strength) & deposit fibrin
o Capillary formation & increased blood supply
9
Q
What are the clinical observation for Proliferative phase?
A
- Wound appears beefy, red, moist
o granulation tissue - Fragile tissue that bleeds easily
o Angiogenesis - Wound paler, tissue is thin, pink
o epithelialisation
10
Q
What is the Maturation & Remodelling phase
A
- Occurs from around day 21 up to 1-2 years after the injury.
- Strengthening and reorganising collagen fibres:
- New tissue continues to grow and develop
- Normal blood supply recreated
- Scar formation and wound contraction
11
Q
What are the clinical observation for Maturation & Remodelling phase?
A
- Scar appears smaller, flatter and paler
12
Q
What are the different types of wounds?
A
- Abrasions
- Lacerations
- Pressure injuries
- Skin tears
- Suture lines
- Burns
- Surgical Wounds: suture lines, drains
- Ulcers- Venous, Arterial Wounds
- Pressure Ulcers
- Incontinence Associated Dermatitis (IAD)
13
Q
What are the components of a wound assessment?
A
- Type of wound - Acute or Chronic
- Aetiology - Surgical, ulcer, burn, pressure injury, bite, skin graft, skin tear
- Location - Where on the body
- Surrounding skin - Dry, tissue paper
- Wound edge - Macerated, Dry, Raised
- Exudate
- Pain
- Odour
- Measurement and dimensions - Length, width, depth
14
Q
Define an acute wound
A
- Primary intention or
secondary intention - <4 weeks
15
Q
Define a chronic wound
A
- Secondary intention
- Normal healing disrupted
- > 4 weeks
