Q

What is an acute wound? How can it be caused? How do they heal?

A

It is the result of tissue damaged by trauma. This may be deliberate, as in surgical wounds of procedures, or be due to accidents caused by blunt force, projectiles, heat, electricity, chemicals or friction. An acute wound is by definition expected to progress through the phases of normal healing, resulting in the closure of the wound.

Q

What is a chronic wound? How do they heal?

A

A Chronic Wound fails to progress or respond to treatment over the normal expected healing time frame (4 weeks) and becomes “stuck” in the inflammatory phase. Wound chronicity is attributed to the presence of intrinsic and extrinsic factors including medications, poor nutrition, co-morbidities or inappropriate dressing selection.

Q

What is a wound?

A

A wound by true definition is a breakdown in the protective function of the skin; the loss of continuity of epithelium, with or without loss of underlying connective tissue(i.e. muscle, bone, nerves).

Q

Describe wound healing in acute and chronic wounds?

A

Acute wound healing follows an orderly sequence of biological events, requiring minimal intervention.

In chronic wounds this sequence of events is disrupted or fixed at one or more of the stages of wound healing and wound-bed preparation is required for healing to occur.

Q

describe a periwound

A
  • Widespread hyperproliferation at wound margin
  • Inhibition of apoptosis
  • Fibroblasts from chronic wounds found to be senescent
18
Q

what should the nurse look at when assessing wound exudate?

A

Quantity: Dry, Low, Moderate, High 

Characteristics: Serous- Straw coloured thin fluid, Haemoserous- Blood stained, Purulent- Green/Brown/Yellow thick fluid

Moisture Imbalance: Desiccation slows cell migration, Excessive fluid causes maceration of wound margin

19
Q

what is chronic wound exudate? why is it bad?

A

Chronic wound exudate has a different chemical composition which may cause a problem in itself. It not only contains water but also bacteria and dead white cells. There are high levels of inflammatory mediators and protein digesting enzymes. Chronic wound exudate is detrimental to healing and more corrosive to peri-wound skin.

20
Q

what 9 things increases risk of wound infection?

A
  • Foreign bodies
  • Haemotoma
  • Diabetes
  • Rheumatoid arthritis
  • Immunosuppression
  • Necrotic tissue
  • Poor nutrition
  • Steroids
  • Wound location
21
Q

define wound infection

A

Wound infection is the presence of replicating microorganisms within a wound with subsequent host injury

22
Q

what are 6 signs of wound infection?

A
  • Heat to surround tissue
  • New slough/necrosis (deteriorating wound bed)
  • Increasing pain
  • Increasing exudate
  • Increasing odour
  • Friable granulation tissue
23
Q

what is the criteria for identifying wound infection?

A
  • Abcess
  • Cellulitis
  • Discharge
  • Delayed healing
  • Discolouration
  • Friable, bleeding granulation tissue
  • Unexpected pain/tenderness
24
Q

what is the ideal healing environment for wounds?

A

warm and moist

25
Q

what is debridement

A

removal of necrotic/sloughy tissue

26
Q

what is absorption (in wound healing)

A

removal of excess fluid from wound bed

27
Q

what is hydration (in wound healing)

A

addition of moisture to dry wound bed

28
Q

what is protection (in wound healing)

A

from mechanical/biological factors which may delay/prevent healing

29
Q

a moist wound healing environment enhances re-__________ in wounds but excessinve fluid can slow down healing and cause _______. Acute wound fluid is different from chronic wound fluid. Chronic wound fluid is seen as a _______ _____

A

a moist wound healing environment enhances re-EPITHELIALISATION in wounds but excessinve fluid can slow down healing and cause MACERATION. Acute wound fluid is different from chronic wound fluid. Chronic wound fluid is seen as a WOUNDING AGENT

30
Q

how does ineffective management of wound exudate effect healing?

A

it will have a negative effect on wound healing, and surrounding skin either by allowing the tissues to get too dry or too wet.

31
Q

what would a wound with low exudate appear like? what dressing type does it need?

A

Wound tissues moist, moisture evenly distributed in wound, <25% of dressing soiled
Do not apply a foam dressing. Apply a simple dressing.

32
Q

what would a wound with moderate exudate appear like? what dressing type does it need?

A

Wound tissues saturated, drainage may not be evenly distributed in wound, 25% - 75% of dressing soiled.
Apply dressing designed to manage moderate exudate and provide bacteriostatic barrier.
Foam not always required.

33
Q

what would a wound with heavy exudate appear like? what dressing type does it need?

A

Wound tissues bathed in fluid, drainage freely expressed, may not be evenly distributed in wound, >75% of dressing soiled
Apply dressing designed to manage heavy exudate. Foam probably required

34
Q

what would a wound with excessive exudate appear like? what dressing type does it need?

A

Exudate not contained by highly absorbent foam
Consider if wound requires primary dressing.
Apply highly absorbent dressing or drainable appliance

35
Q

how should infection be managed?

A

Treat infection systematically
Treat local characteristics affecting wound bed
Treat surrounding skin

36
Q

when should you NOT routinely take swabs? why?

A

if the wound is a chronic ulcer, a pressure ulcer, wound over a month old, sinuses and fistulae, and stoma sites
This is because these wounds will always have growth since they will be colonised with the patients own flora/environmental organisms

37
Q

when should you take a wound swab?

A

evidence of spreading cellulitis, clinical signs of infection (temp, WCC, etc), immunosuppression (diabetes, steroids, malignancy)

38
Q

define wound cleansing

A

Wound cleansing is “the process of using fluids to remove loose wound debris and remnants of dressings. This process should not be confused with wound debridement.”

39
Q

what 5 things need considered when selecting a wound dressing?

A
  • What is the action of dressing? 􏰀
  • When should it be used?
  • Any contraindications?
  • Application and removal methods 􏰀
  • Is a secondary dressing required?
40
Q

what should ideal dressings provide?

A
  • Moist environment
  • Thermal insulation
  • Low or non adherent 􏰀
  • Absorbs exudates
  • Cost effective 􏰀
  • Protection
  • Pain relief
