Leg Ulcers Flashcards
What is a leg ulcer
Any break in the skin of the lower leg above the ankle present more than 4 weeks
What are the majority of leg ulcers
Venous
What are 2 underlying diseases that can cause leg ulcers
Rheumatoid
Diabetes
How much of the population in the UK will have an ulcer in their lifetime
1%
80% of patients with a leg ulcer need to be admitted. True or False
False
more than 80% can be managed in the community
Why are leg ulcers important
Morbidity (pain, sepsis, exudate, odour)
Impaired quality of life
Financial cost
What type of young patients may develop a venous ulcer
Diabetics
Substance abusers
What types of leg ulcers are there
Venous Arterial Mixed venous and arterial Diabetic Vasculitic Malignant Hydrostatic
Venous ulcers are often recurrent. True or False
True
What might the location of the ulcer give us clues about
The underlying cause
What are some of the signs of venous disease
Ankle swelling Varicose veins Lipodermatosclerosis Hyperpigmentation Malleolus
What is slough
Dead tissue/ debris that needs to be removed
WHat is the normal range of an ankle/brachial pressure
0.8-1.3 normal
How can you calculate the ABPI
ankle pressure / brachial pressure
If the ABPI is
There is vascular disease
If the ABPI is >1.5 what does this mean?
Calcification - there are hardened arteries and having a compression bandage would not work as the arteries are too occluded. Further investigation and treatment would be required first before compression
Why would you swab an ulcer
If there are signs of infection
What are the signs of infection of an ulcer
Increasing pain
Exudative
Smelly
Enlarging
What blood tests would you do for a suspected infected leg ulcer
FBC
LFT
U&E
CRP
What is the treatment for a venous ulcer
Control pain
ABPI
Non-adherent dressing
De-sloughing agent if necessary e.g. hydrogel/ honey
4 layer compression bandaging - may need to increase compression gradually if pain a problem
Leg elevation
Describe a 4 layer bandaging system
Graduated compression
What pressure should be applied to the leg
40mmHg at ankle and 25mmHg below the knee
Why do we shape the leg into a cone
To aid with the pressure gradient
How long should all ulcers be healed by
12 weeks
