1
Q

How can you heal a wound

A
Provide good local wound care (dressings,
debridement, and infection control)
• Increase mobility
• Increase nutrition
• Address the cause of the wound
2
Q

what is a primary wound care dressing

A

dressing is placed directly in

contact with the wound bed.

3
Q

what is a secondary wound care dressing

A

dressing is placed over the
primary dressing provide more absorption
and/or to hold it in place.

4
Q

Why is it important to provide a moist wound environment

A

a moist wound environment encourages autolytic
debridement, and reepithelialization. If a wound
is too dry, cells die and epithelialization is
significantly slowed. If a wound is too wet, then
the surrounding skin will macerate and can
promote infection

5
Q

How can you protect the wound from the outside environment

A

A good dressing

will also protect from friction, shearing forces, and contamination from microorganisms, urine and stool.

6
Q

Goals of wound care dressings

A
Provide a moist wound environment:
Protect from the outside environment
Be easily applied and removed
Will be semipermeable and
maintain gas exchange
Will be free from either particulate or toxic
contamination
Will be thermally insulating
Cost effective
May be used in combination with
compression therapy
Simple treatment
7
Q

What is the most absorbent type of wound dressing

A

Foam/ABD pads/superabsorbents

8
Q

what is the least absorbent type of wound dressing

A

transparent film

9
Q

Why is silver now added to almost every wound care product

A

Silver ions are selectively toxic to bacteria

10
Q

What is transparent film good for

A

Good secondary dressings, which hold the
primary dressing in place, repel urine and stool, and reduce friction.
this is not a good primary dressing
it is bad for heavily draining wounds

11
Q

what is non-adhering gauze used for

A

primary dressing when the goal is to not disrupt the wound bed

12
Q

What is gauze good for

A

Good for cleaning wounds, and is frequently used with tap water or saline solution for this

13
Q

Why is gauze not a good primary dressing

A

Causes loss of heat,
permeable to bacteria, urine and stool, can leave gauze fibers in the
wound. Frequent dressing changes needed.

14
Q

What can rolled gauze be used for

A

Acceptable for packing wounds, and also used to wrap dressings in place as a secondary or tertiary dressing.

15
Q

what is vaseline gauze good for

A

skin tears, skin grafts, or painful wounds

16
Q

what is vaseline gauze bad for

A

cannot be used by itself on any wound that is

moderately or heavily exudating

17
Q

what are hydrogels used for

A

dry wounds (to add moisture), necrotic wounds (to promote autolytic debridement), and wounds with difficult to see areas of
undermining and tunneling (“amorphous’)
not suitable for moderately or heavy exudating wounds

18
Q

what are hydrocolloids used for

A

dry wounds (to add moisture), necrotic wounds (to promote autolytic debridement), and wounds with difficult to see areas of
undermining and tunneling (“amorphous’)
not suitable for moderately or heavy exudating wounds

19
Q

What are alginates made from

A

derived from seaweed these dresseings are good as primary dressings and with moderately to heavy exudating wounds
bad for dry wounds

20
Q

what are foam/ABD pads used for

A

used as primary dressings and for moderately to heavily exudating wounds

21
Q

What is negative pressure wound therapy

A

both a dressing and a wound healing modality in one that is good for wounds with signifcant drainage and depth

22
Q

contraindications for negative pressure wound therapy

A

Contraindicated over malignancy, and

untreated osteomyelitis, necrotic wounds, sensitivity to silver

23
Q

what are composites

A
Any combination of two or more
dressings in one product.
• Usually has an adhesive layer, and
absorptive layer, and a physical outer
barrier to bacteria / urine / stool
24
Q

what are composites useful for

A

good for Wounds that require two or more steps to perform a dressing that can be greatly simplified in one dressing.

25
Q

what is enzymatic debridement used for

A
wounds that  require debridement due to the presence of
necrotic tissue (slough or eschar)
26
Q

what are CYTOTOXIC CLEANSING AGENTS, ANTIBACTERIAL/

ANTIMICROBIAL OINTMENTS AND SOLUTIONS used for

A

Wounds that require topical management of bacteria and other microorganisms, especially drug-resistant infections.

27
Q

what is the purpose of multi-layer compression bandages

A
achieve graduated compression.
•used to manage venous
hypertension, lymphedema, and venous insufficiency wounds
•improves venous return to the heart
•may need ABI beforehand
28
Q

in what direction do you want compression to increase

A

compression should increase distally down the leg

29
Q

MULTI-LAYER

COMPRESSION BANDAGES are good for:

A

Venous insufficiency wounds. Short-term management of

lymphedema

30
Q

who uses recombinant growth factor

A

patients with diabetic foot ulcers that have stalled progress because it stimulates cell growth and migration

31
Q

what is collagen used for

A

wounds that have stalled progress (chronic wounds), and where subclinical
signs of infection are present and excess MMP’s are suspected

32
Q

what are cellular/tissue-based products used for

A

chronic wounds, especially where skin grafting is not

possible due to the age of the patient
