Wound care Flashcards
Proficiencies that are related to ANTT
- Acting as a role model in providing evidence based, person centred care to meet the needs of people
- Use aseptic non touch techniques effectively
- use of aseptic technizuess when managing wound and undertaking wound care
Functions of the skin
Protection- from injury and microorganisms which could cause infection
Sensation- nerves in skin allow is to feel pain and touch and pick up temp
Temperature- Helps regulate body temp
How do wounds occur
- Intentional- during operation
- Trauma- mechanical or chemical injury
- Circulatory problems- loss of O2 in tissues cause skin breakdown ( Ischemia)
- Moisture from bodily fluids left on skin can cause skin breakdown/ pain
- Pressure - causes by lying in the same position for long time
Types of wounds you may come across in practice
nappy dermititis
surgical wounds
congenittal abnormalities (epidermolysis bullosa)
dog bites, cuts, burns/scalds
pressure sores
Processes of wound healing
- Heamostasis( stop bleed via platelets)
- Inflammation- redness, swelling, pain
- Proliferation (new cells made)
- Remodelling- starts three weeks after injury
Duration of each healing process
haemostasis= minutes
Inflammation- Days
Proliferation- weeks
Remodelling- Months to years
What can wound healing be affected by
- poor nutrition
- lack of sleep
- Pain
- Anxiety
- infection
- Diabetes
- Anaemia
Acute and chronic wound
Acute- recent wound
When acute doesn’t heal –> chronic
Infected wounds cause/ signs of infected wound
- Redness
- Swelling
- Pain
- Discharge
- Bad odour
- Heat- high temp
Wound swabs must be taken adn sent to lab if infection suspected
Things to consider when assessings wound
Serous
Sanguineous
Serousanguineous
Purulent
Serous
Normal drainage
Clear watery fluid
Tinge brown due to old blood
Sanguineous
Bloody drainage=fresh bleeding
Normal in fresh wounds
Serousanguineous
Normal drainage
Combination of serous and sanguineous
Thin, red and watery
Purulent
Abnormal drainage
Indicates infection (AKA Pus)
thick milky drainage
Different types of Skin tissue wound
Necrotic- mass of dead cells
Eschar- type of necrotic tissue. White or black
Slough- Moist necrotic tissue
Granulation- New connective tissue
Scab-Protects the wound by tapping pathogens
Callus- Thick hard skin
