Q

Principles of Wound Cleansing

A

 Use Aseptic technique
 Wound cleansing should not be undertaken to remove ‘normal’ exudate
 Cleansing should be performed in a way that minimises trauma to the wound
 Wounds are best cleansed with sterile isotonic saline or water
 The less a wound is disturbed during dressing changes the less interference there
is to healing
 Fluids should be warmed to 37°C to support cellular activity
 Skin and wound cleansers should have a neutral pH and be non-toxic
 Avoid alkaline soap on intact skin as the skin pH is altered, resistance to bacteria
decreases
 Avoid delipidising agents as alcohol or acetone as tissue is degraded
 Antiseptics are not routinely recommended for cleansing and should only be used
sparingly for infected wounds

Q

eferred method for cleansing open

wounds

A

Irrigation
This may be carried out utilising a syringe in order to
produce gentle pressure - in order to loosen debris

3
Q

Gauze swabs and cotton wool should be used with caution as can wound cleansing

A

cause mechanical damage to new tissue and the
shedding of fibres from gauze swabs/cotton wool delays
healing.

4
Q

Dressings can be catagorised into four types:

A

Primary dressing:
Secondary dressing
Occlusive dressing:
Semi-occlusive dressing:

5
Q

Primary dressing:

A

is one that comes directly in contact with

the wound bed

6
Q

Secondary dressing

A

is used to cover a primary dressing
when the primary dressing does not protect the wound from
contamination

7
Q

Occlusive dressing:

A

covers a wound from the outside
environment and keep nearly all wound vapours at the
wound site

8
Q

Semi-occlusive dressing:

A

allows some oxygen and moisture

vapour to evaporate

9
Q

Dry wound dressing

A
Non adherent island dressing
Hydrocolloid
Films semi
permeable
Silicone absorbent
10
Q

Minimal exudate dressing

A

Hydrogel Hydrocolloid Foams

11
Q

Moderate exudate dressing

A

Calcium alginate
Hydrofibre Negative Pressure
Hydrocolloid: paste/powder

12
Q

Heavy exudate dressing

A

Hydrofibre Foam
Absorbent dressing
Negative pressure wound therapy
Ostomy bags
