Q

What are the types of granulation tissue?

A
  1. Hypergranulation tissue - overdrive = not great for wound healing
  2. Beefy red granulation tissue = this is what you are looking for
  3. Hypogranulation - hardly any possibly due to decreased blood flow to that area

Q

What are pressure ulcers a result of and where do they often develop?

A
  • Result from pressure or repetitive pressure at the same anatomical locatin
  • Often develop at bony prominences

Q

What is the treatment for pressure ulcers?

A
  1. Relieve/remove pressure
    1. air beds, padded seat covers, sheep skin, boots
  2. Treat wound as it is assesses
    1. Maceration
    2. Eschar
    3. Infection

Q

What is the function of an Alginates dressing?

A
  • Made from seaweed - silver in it to help keep microbes at bay
  • Exudate absoprtion
  • Pulls wetness away from wound

Q

What is the function of Gauze dressings?

A
  • Retain mositure
  • Debride (wound sticks to gauze - upon removal, takes good tissue too)

Q

What should you do when addressing nonhealing wounds?

A
  1. Assess the entire patient
  2. Systemic problems impair wound healing
    1. Smoking delays wound healing!
  3. Consider endocrinology problems
17
Q

What should you be documenting for wounds?

A

Characterize the wound:

  • Size and depth measurements
  • Appearance of wound (foreign body, debris?)
  • Amount of drainage (type)
  • Appearance of surrounding tissue
18
Q

If a wound is nonhealing what else should you consider?

A
  • Malnutrition
  • Vit C and Zinc common supplements for woundcare
  • Treat infection is present
19
Q

What is the protein requirement in a healthy patient? What about for wound healing?

A
  • 1.25 - 1.5 grams of protein/kg
  • More for wound healing (increase as tolerated)
20
Q

What are risk factors for venous ulcerations (stasis)?

A
  • Varicose veins
  • DVT
  • Chronic venous insufficiency
  • Poor calf muscle function
  • Ovesity
21
Q

Where do 95% of venous ulcerations occur on the body?

A

Gaiter area of the leg (think “sock distribution” of the leg)

22
Q

Common signs and sypmtoms of a venous ulcer?

A
  • Edema often present
  • Hemosiderin staining
  • Hair loss of extremity
  • Weeping and itchin gof skin often present
23
Q

What is the treatment for a venous ulceration?

A
  1. Compression therapy (stockings)
    1. Appropriate for ulcers caused by edema
    2. Avoid if arterial flow compromised
    3. 40-60 mmHG of pressure (Unna boot)
  2. Elevation of extremity
  3. Woundcare and assessment
24
Q

What causes arterial ulcerations and what do they result in?

A
  • Due to decreased arterial blood supply to the LE
    • PVD, DM, Sickle Cell
  • Results in tissue hypoxemia and damage
  • Reduced capillary refill time
25
What are common signs and symptoms of arterial ulcers?
* Painful * Ulcer appeared "punched out" * Well demarcated edges * Pale, often necrotic base * Surrounding skin dusky, shiny, hairless * Usually occur over the toes, foot, and ankle
26
What is the treatment for arterial ulcers?
1. Restore arterial function if possible 1. SX usually 2. Wound treatment 3. Smoking cessation Note: Medication susually not helpful
27
What is an ankle brachial index (ABI) helpful in determining?
The extent of peripheral vascular disease
28
How is an ABI performed?
* Systolic BP measure in both brachial arteries * Systolic BP then measure in both dorsal pedis/psoterior tibial arteries * Pt should be at rest and supine for 10 mins.
29
What is a normal value for an ABI?
1.0 - 1.4
30
What does an ABI value \> 1.4 suggest?
A noncompressible calcified vessel
31
What does an ABI value \< 0.9 indicate? What about \< 0.5?
* \<0.9 = moderate PAD --\> Refer to vascular specialist * \< 0.5 = Severe PAD --\> Refer to vascular specialist
32
What are the 3 main ways negative pressure wound therapy (wound vac) enhances wound healing?
1. **Reducing edema** 2. Increasing rate of **granulation tissue formation** 3. **Stimulation of circulation**
33
What types of wounds are wound vac used for?
* Chronic and Acute wounds * Traumatic wounds * Partial thickness * Dehisced wounds * DM ulcers * Pressure ulcers
34
What are contraindications for the use of wound vac therapy?
* Malignancy of wound * Untreated osteomyelitis * Placement of dressing in contact with exposed blood vessels, organs, or nerves * Nonenteric or unexplored fistulas
35
What are the 2 types of growth factors we talked about called?
1. Apligraf - human derived 2. Dermagraft
36
What are some debridement methods?
1. Enzymatic-chemical agents (most taken off market) 2. Mechanical-wet to dry dressings- gauze (peroxide debridement controverial) 3. Sharp-surgical removal (done by surgeon)
37
What is involved in the follow up care of wounds?
* Close monitoring * Weekly visits * Careful documentation
