Q

4 stages of wound healing?

A

Hemostats
Inflammation
proliferation
maturation

21
Q

Hemostasis

A

blood vessels constrict clotting begins Exudate is released causing swelling and pain

22
Q

Inflammation

A

Inflammatory phase- follows hemostasis & lasts 4-6 days. WBC mainly luekocytes move to the wound. Macrophages arrive about 24 hours after injury to ingest debris & release growth factors. The patient will have pain, heat, redness & swelling at the site. A mildly elevated temp,

23
Q

proliferation

A

Proliferation phase- lasts for several days; filling of the wound with granulation tissue primarily thru the action of fibroblasts. Highly vascular, red, & bleeds easily. If healing by primary intention, epidermal cells seal the wound within 24-48 hours. Collagen synthesis and accumulation continue. Depending on the size of the wound can take several weeks to years. By the end of the second week the majority of WBC have left the wound area & the wound is lighter in color.

24
Q

maturation

A

Maturation phase- Begins about 3 weeks after the injury. A scar forms- an avascular tissue that does not sweat, grow hair, or tan in sunlight. It is less elastic than uninjured tissue. Wounds that heal by secondary intention take longer to remodel.

25
Primary intention-
Primary intention- healing occurs by epithelialization; heals _Quickly(skin is connected still) with minimal scar formation
26
Secondary intention(open wound)-
Secondary intention(open wound)- wound heals by granulation _tissue_ formation, wound contraction, and epithelialization
27
Tertiary or delayed primary-
Tertiary or delayed primary- closure of wound is delayed until risk of infection is resolved(we open the wound to try to get dangerous infection out)
28
Exudate
The accumulation of exudate causes swelling and pain.
29
What local factors effect healing?
``` LOCAL FACTORS: Pressure(longer to heal) Desiccation( extreme dryness) Maceration Trauma Edema Infection Excessive _Bleeding_ Necrosis(dead tissue in the way) Biofilm ```
30
What systemic factors effect healing?
``` SYSTEMIC FACTORS: _Age_ Circulation to & oxygenation of tissues Nutritional status(don’t eat protein slower heal) Wound etiology(what caused wound?) Health status(diabetic) Immunosuppression Medications Adherence to treatment plan ```
31
desiccation
the process of drying up delays healing wound should be kept moist(not wet)
32
maceration
over-hydration breakdown of skin to over hydration likely from incontinence
33
necrosis
death of tissue appearance of eschar dry black dead tissue wound will not heal with dead tissue present
34
biofilm
result of wound bacteria growing in clumps and weaking resistances
35
Dehiscence
Dehiscence(wound opened back up)
36
Evisceration
Evisceration(organs intestines comeing out of the wound)
37
Fistulas
an abnormal passage from an internal organ to the outside of the body
38
CLASSIFICATION OF PRESSURE ULCERS | STAGE I
Intact Change in skin _turgor_, tissue consistency, and/or sensation Defined area of persistent redness- light pigment Persistent red, blue, or purple hues- darker skin tones
39
CLASSIFICATION OF PRESSURE ULCERS | STAGE II
Partial thickness _skin_ loss involving epidermis and/ or dermis Superficial Abrasion, blister, or shallow crater
40
CLASSIFICATION OF PRESSURE ULCERS | STAGE III
Full-thickness __skin__ loss involving damage or necrosis of subcutaneous tissue Does not extend thru underlying fascia Deep crater w/ or w/o undermining of adjacent tissue
41
CLASSIFICATION OF PRESSURE ULCERS | UNSTAGEABLE PRESSURE INJURY
Full-thickness skin and tissue loss in which the extent of the tissue damage within the ulcer cannot be confirmed because it is obscured by slough or eschar. If slough or eschar is removed, a stage 3 or 4 pressure ulcer will be revealed. Stable eschar on the heel or ischemic limb should not be softened or removed.
42
CLASSIFICATION OF PRESSURE ULCERS | STAGE IV
STAGE IV Full- thickness __skin__ loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures May have undermining & sinus tracks
43
abcess
infected fluid that has not drained
44
“Pressure Ulcers increase hospital costs significantly. In the US, pressure ulcer care is estimated to approach $__ (USD) annually, with a cost of between $___ (USD) and $__ (USD) per individual pressure ulcer
“Pressure Ulcers increase hospital costs significantly. In the US, pressure ulcer care is estimated to approach $11 billion (USD) annually, with a cost of between $500 (USD) and $70,000 (USD) per individual pressure
45
FACTORS WHICH INFLUENCE PRESSSURE ULCER FORMATION
``` Nutrition Tissue perfusion Infection Age Psychosocial impact ```
46
Discuss nursing assessment of skin integrity and wound healing.
Identify the client’s __risk__ for developing impaired skin integrity Identify signs and symptoms associated with impaired skin integrity or __poor__ wound healing Examine client’s skin for actual impairment in skin integrity Skin Pressure ulcers- _predicted measures_ measures; mobility, nutritional status, body fluids, & pain. Wounds- emergency setting(control bleeding) vs. stable setting(prevent infection) ``` others Wound appearance Character of wound drainage Drains Wound closures Palpation of wound Wound cultures Client expectations ```
47
What are some wound related nurseing diagnosis?
Risk for _infection_ Acute or chronic pain Impaired skin integrity Risk for impaired skin integrity Imbalanced nutrition- less than body requirements Impaired physical mobility Ineffective tissue _perfusion_
48
debidement
(removal) devitalized tissue removal Necessary to rid the ulcer of a source of infection Enable visualization of the wound bed Provide a clean base necessary for healing “heel ulcers w/ dry eschar need not be debrided if they do not have edema, erythema, fluctuance, or drainage.” May observe an increase in wound exudate, odor, and ____ Manage pain
