Midterm module 2 Acute & Chronic Wounds Flashcards
Wound definition
any disruption to the layers of the skin & underlying tissues
what are the 3 main types of wound healing
1) Primary intention
2) Secondary Intention
3) Tertiary Intention
four main parts of wound healing
1) Hemostasis
2) Inflammation
3) Proliferation
4) Remodelling
What is an acute wound
Heals within an expect time frame (Within 21 days)
What is a chronic wound
normal process of wound healing is disrupted at one or more points in the phases of wound healing. Long duration. Reoccurs frequently. (Pressure ulcers, venous ulcers, arterial ulcers, diabetic foot ulcers)
What are pressure injuries
localized areas of infarcted soft tissue that occur when pressure is applied to the skin over time is greater than normal capillary closure pressure which his 25-32 mmHG
Eat are the risk factors for pressure injuries
1) Prolonged pressure on tissue
2) Immobility, compromised mobility
3) Loss of protective reflexes, sensory deficit/loss
4) Poor skin perfusion, edema
5) MAlnutiritoion, hypoproteinemia, anemia, vitamin deficiency, overweight/underweight
6) Friction, shearing, trauma
7) In continence of urine of feces
8) altered skin moisture, excessively dry or moist
9) Advanced age, debilitation
10) Critically ill patients
11) casts, traction, restraints
how often should you assess total skin condition
twice a day
What are the pressure ulcer interventions
1) Attending to the contributing factors
2) Maintain good skin hygiene & avoid skin trauma
3) Providing supporting devices to maintain uncompromised circulation
4) Frequent positioning
5) Multidisciplinary approach & individualized care
6) Local wound care & debridement, bacterial & moisture balance
what can cause lower limb ulcers?
Diabetes
Arterial or venous insufficiency
what is the assessment & treament of lower limb ulcers
1) aided by doppler ultrasounds
2) compression dressing?
3) interdisciplinary
What are the characteristics of venous ulcers
1) 75% of leg ulcers caused by chronic venous insufficiency
2) Dull aching or heavy
3) edema
4) Typically large & superficial wounds
5) Highly exudative
6) Irregular ulcer border
7) Pulses pressent
8) Bleeds easily
9) Location: gaiter area, especially the medial malleolus
how can we prevent venous ulcers
1) restore skin integrity, improve physical mobility, nutrition & absence of complications
2) Compression of the extremity
3) Elevation
4) Protection from trauma
5) Skin kept clean, dry & soft
what are the risk factors for atherosclerosis & PAD
Nonmod: Age, Gender, genetics Mod: -Nicotine -diet -hypertension, diabetes, obesity -stress, sedentary lifestyle -elevated CRP -hyperhomocysteinemia
what are the characteristics of arterial ulcers
1) 20% of leg ulcers are arterial
2) Claudication
3) Digital or forfeit pain @ rest
4) Smooth/regular shaped borders
5) Small, circular, deep
6) Non-blleding
7) Weak pulse or not palpable
8) pale of black
9) On of between toes, hell, shin or medial hallux
