21
Q

Pressure ulcer

A

Pressure sore, decubitus ulcer, or bed sore

22
Q

Pathogenesis of pressure ulcers

A
  • Pressure intensity
  • Tissue ischemia
  • Pressure duration
  • Tissue tolerance
23
Q

Stage 1 pressure ulcer

A

Intact skin with non-blanchable redness

24
Q

Stage 2 pressure ulcers

A

Partial-thickness skin loss involving epidermis, dermis, or both

25
Q

Stage 3 pressure ulcers

A

Full-thickness skin tissue loss with visible fat

26
Q

stage 4 pressure ulcers

A

Full-thickness tissue loss with exposed bone, muscle, or tendon

27
Q

Beyond stage 4 pressure ulcer

A

Deep tissue pressure injury

Unstageable pressure injury

28
Q

Deep tissue pressure injury (DTPI)

A
  • Persistent non-blanchable deep red, maroon, or purple
  • Skin may be intact or nonintact
  • Intense and/or prolonged pressure and shear forces down deep.
  • May/may not open up.
29
Q

Unstageable pressure injury

A
  • Obscured full-thickness skin and tissue los

- Obscured because of slough or eschar are present

30
Q

What do you want to avoid with wound healing

A

Hemorrhage

Infection

31
Q

Risk assessment for pressure ulcers

A

Braden scale

— sensory, moisture, activity, mobility, nutrition, friction/shearing

32
Q

Prevention of pressure ulcers

A
  • Beds, mattresses, good hygiene, good nutrition (check labs), adequate hydration, impeccable nursing care.
  • Time and amount of pressure = key variables
  • Increases hospital Length of Stay (LOS) = $$$
  • Pain/suffering
33
Q

Factors influencing pressure ulcer formation and wound healing

A
Nutrition 
Tissue perfusion 
Infection 
Underlying heath status 
Age 
Use of steroids 
Site of wound 
Mechanism of injury
34
Q

Infection prolongs

A

Inflammatory phase and delays healing

35
Q

Aging dermis tends to

A

not support sutures well

36
Q

Wound prevention

A
  • Skin care
  • Continence Management
  • Positioning
  • Support surfaces
  • –Low-air-loss mattress/overlay
  • –Non-powered: cushions, foam
  • –Air-fluidized beds: change load distribution/pressure
  • –Lateral rotations: passive turning
37
Q

Assessment of skin/wounds

A

Through the patient’s eyes: impact, OLDCART
Assess skin at intake into facility/care
Appearance
Drainage:
—Amount
—Color
——Serous/Sanguinous/Serosanguinous/Purulent
—Odor
—Consistency
—Cultures
Peri-wound: tissue surrounding actual wound

38
Q

Risk factors for pressure ulcers

A
Impaires sensory perception 
Alterations in LOC 
Impaired mobility 
Shear 
Friction 
Moisture 
Nutrition 
Hydration
39
Q

Wound cultures

A
Clean wound surface with a non-antiseptic solution
Use sterile swab from culturette  tube
Moisten swab with normal saline
Rotate swab in open wound
Reinsert into transport tube.
40
Q

Wound management

A
Debridement 
Closures 
Protection 
Education 
Nutritional status
41
Q

Debridement (removal of nonviable, necrotic tissue)

A

Mechanical, autolytic, chemical, or sharp/surgical
Sharp/surgical only w/NP or CWN, not general nurses
Wet to dry dressing

42
Q

Closures

A

Sutures, staples, steri strips, derma bond adhesive

43
Q

Protection

A

dressings and wraps

44
Q

Nutritional status

A
  • Caloric needs
  • Albumin/pre-albumin
  • Can lose up to 50 G of protein /day from weeping ulcer
  • Hemoglobin maintain> 12 if possible
45
Q

First aid for wounds

A

Hemostasis
Cleaning
Protection

46
Q

Ways to control bleeding

A

Allow puncture wounds to bleed

Do not remove a penetrating object!

47
Q

Purposes of dressing

A
  • Protect from microorganism contamination
  • Aid in hemostasis
  • Absorb drainage and debriding a wound
  • Support or splint the wound site
  • Protect from seeing the wound (if distressing)
  • Promote thermal insulation of the wound.
48
Q

Types of dressing

A
Gauze
Self-adhesive/transparent film
Hydrocolloid dressings
Hydrogel
Foam
Alginate
Composite dressings
49
Q

Wound devices

A

Penrose drain
Jackson-Pratt drainage
V.A.C (vacuum assisted closure)

50
Q

VAC: Vacuum assisted closure

A
  • Reduces edema/swelling
  • Improves circulation to the wound
  • Facilitates wound healing and decreases duration of wounds.
  • Drawback: Risk for bleeding
