pressure ulcers Flashcards
define pressure ulcer
localisd injury ot the skin and/or underlying tissue ususally over a bony prominence as a result of
- pressure
- combination with shear
- small, superficial wounds or blisters
- epidermal elements
covered or filled with necrotic tissue - deeper tissues
– fascia
– muscle
– bone
key diagnostic factors
- presence of risk factors
- use of non-pressure-relieving support surface
- localised skin changes on areas subjected to pressure
- blister/shiny/dry shallow ulcer
- – partial loss of dermis WITHOUT SLOUGH - grade 2 ulcer
what are localised skin changes seen on areas subjected to pressure
non-blanching erythema/purple/,arror
- painful
- firm
- mushy
- boggy
- warmer/cooler than adjacent tissue
predisposing factors of pressure ulcers
malnourishment
incontinence
lack of mobility
pain (leads to a reduction in mobility)

grading of ulcers tool name
European Pressure Ulcer Advisory Panel classification system.
grade 1 ulcer
Non-blanchable erythema of intact skin. Discolouration of the skin, warmth, oedema, induration or hardness may also be used as indicators, particularly on individuals with darker skin
grade 2 ulcer
Partial thickness skin loss involving epidermis or dermis, or both. The
ulcer is superficial and presents clinically as an abrasion or blister
grade 3 ulcer
Full thickness skin loss involving damage to or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia.
grade 4 ulcer
Extensive destruction, tissue necrosis, or damage to muscle, bone or
supporting structures with or without full thickness skin loss
management of pressure uclers
- a moist wound environment encourages ulcer healing. Hydrocolloid dressings and hydrogels may help facilitate this. The use of soap should be discouraged to avoid drying the wound
- wound swabs should not be done routinely as the vast majority of pressure ulcers are colonised with bacteria. The decision to use systemic antibiotics should be taken on a clinical basis (e.g. Evidence of surrounding cellulitis)
- consider referral to the tissue viability nurse
- surgical debridement may be beneficial for selected wounds
