Q

Maceration

A

overly wet area

healthy tissue breakdown

white appearance

*Maceration chronic wounds present with a high level of exudate and whitish, swollen skin. The surface of the skin is roughened and lined with a network of grooves termed as the “sulci cutis”. It is similar in appearance to the white, wrinkly skin observed after spending a long time in a bath.

ABI: 0.6-0.8 can indicate a mixed ulcer

<0.6- the first mode of treatment is to re-vascularize for healing, prevent recurrence
–> no compression

> 0.6: no consensus on treatment; less likely need revascularization

56

A

the stage cannot be reversed when there is healing happening

60
Q

Why does a pressure injury occur?

A

-ischemia and anoxia to tissue

-shear forces, friction forces, pressure forces, moisture

-Tissues are compressed, blood vessels are compressed and blood flow is
diverted by continual pressure on the skin and underlying structures

-cellular respiration impaired and cells die

61
Q

Are pressure injuries in hospitalized patients considered never events?

A

yes

stage III-IV

62
Q

Pressure forces- relationship between intensity versus duration

A

pressure injuries can be caused by:

-prolonged exposure to mild to moderate force

-short exposure to moderate severe forces

63
Q

Friction vs shear:

A

FRICTION
-is a mechanical force exerted when two surfaces move (i.e.: ‘rub’) against another

SHEAR:
-Shear is a stress resulting from applied forces which cause two objects to deform in the transverse plane
-involves friction and gravity
-body layers are laterally shifted in relation to each other
-skeleton moves but skin stays in same place

64
Q

What is a risk that can occur when you raise the HOB?

A

-increased load on sacrum and heels in more upright position

-good HOB height: 30 degrees

65
Q

What populations are skin tears common in?

A

-extremes of age
-critically or chronically ill

-10-54% prevalence in LTC

66
Q

Skin tears: cause and characteristics

A

Caused by shear, friction, and/or blunt force trauma

  • Forces separation of skin layers
  • Can be partial- or full-thickness
  • Slow to heal
  • Susceptible to secondary infection
    -acute wound

high propensity
to develop into chronic wounds.

**IT IS GOOD TO PRESERVE THE FLAP!

67
Q

How can documentation on dressing be modified to keep skin flap in mind?

A

ex: remove in this direction with arrow (the skin flap is oriented in this direction)

date and initials of therapist

67
Q

What is the Braden Scale?

A

-objective scale to determine risk of person developing a pressure ulcer

-SNF, IRF, etc

Population: Most commonly used for patients who are bed- or chair-bound, as well as those with an impaired ability to reposition.

CATEGORIES:
-sensory perception - response to pressure-related discomfort (completely limited, very limited, slightly limited, no impairment)

-moisture (constantly moist, very moist, occ. moist, rarely)

-activity (bedfast, chairfast, walks occ., walks frequently)

-mobility
–> ability to change and control body position
–> (completely immobile, very limited, slightly limited, no limitation)

-nutrition (very poor, probably inadequate, adequate, excellent)

-friction and shear (problem, potential problem, no apparent problem)

** 1-3 or 1-4 scale

** LOWER SCORES–> GREATER RISK OF DEVELOPING PRESSURE INJURY

68
Q

Acute wound vs chronic wound:

A

ACUTE
-TIME: 4-6 weeks
-EXAMPLE: surgical, bites, burns, abrasions, traumatic
-TREATMENT:
–> expected healing within predictable timeframe
–> minimal interventions for minor wound and clean source
–> surgical debridement, antimicrobial therapy, wound lavage for severe wound and dirty source

CHRONIC
-TIME: >6 weeks
–> caused by endogenous mechanisms related to a predisposing condition or risk factors (diabetes, AIDS, chemo)
-EXAMPLE: leg/foot ulcers, pressure injury, foot wound from vascular insufficiency or neuropathy

-TREATMENT:
1.) dressing
2.) antimicrobial agents
3.) physical therapy
4.) education
5.) treat co-morbidities
6.) supportive ints: pressure relief, compression, footwear, ADs

A

nutrition

concomitant med conditions

immunosuppression

thrombocytopenia - lack of platelets

use of anticoagulants -bleeding risk

setting where the patient is

79
Q

What are the 4 types of non-selective/mechanical debridement?

A

-wet to dry: “waxing a wound” - with fully necrotised tissue; standard 30-40 years ago
-irrigation: saline
-hydrotherapy: whirlpool (breakdown of necrotic tissue) –> not efficient
-abraded technique: rubbing on tissue; non-selective; not good for granulation tissue

80
Q

4 types of selective debridement:

A

AUTOLYTIC - assist body’s enzymatic cells in digesting necrotic tissue; often used with wound dressings
*occlusive- hydrocolloid- non infected wounds, days to work
*transparent- non-occlusive, not good for deep wounds or infected wounds
*hydrogel- add moisture and nutrients to area
*med honey- high in osmolarity; low pH (acidic nature helps to neutralize the naturally alkaline wound area) ** manuka honey

BIOSURGICAL
-maggots: they eat bacteria; control exudate; aren’t affected by antibiotics; can bag them or have them be free range

ENZYMATIC
-breaks down proteins necrotic tissue
-good for infected wound with topical antimicrobial
-cannot be used with silver based products
-**promotes angiogenesis
*EXPENSIVE!
EX: collagenase santyl

SHARP/SURGICAL
-conservative: can be done by PT
–> must have physician’s order, goal of 100% granulation tissue
-surgical: only by MD under anesthesia
–> large wound, lots of necrosis, heavily infected,
–> ascending cellulitis, osteomyelitis, extensive necrosis, extensive undermining

81
Q

A

-stable heel eschar
-gangrene (NEED SURGICAL DEBRIDEMENT)
-unidentified structures–> nerve, tendon, ligament, muscles, vessel, fungating wound

-terminally ill
-ABI < 0.8
-coagulopathy: INR, PT/PTT, platelets, hemoglobin

86
Q

MUST HAVES before sharp debridement

A

-Phys. order
-chart review
-check labs
-gather tools
-pre-medicate
-comfortable positioning
-adequate lighting
-cleanse before you debride with saline! (angiocatheter, skin/wound cleanser, bulb syringe)
-measure!!- paper tape measure, cotton tip applicator

87
Q

Should you measure the wound before or after you debride it?

A

before AND after

88
Q

Techniques for selective debridement:

A
  • Hold scalpel like a pencil
  • Cut parallel to skin, not perpendicular
  • Work in layers
  • Use forceps or tweezers to grasp onto layers
89
Q

What is the cross hatching technique of selective debridement used for?

A

Increases surface area for enzymatic debridement

** can help to improve healing of areas with epibole –> increase wound edge closure
-can do this with a curette

-silver nitrate can be used in epibole management as well

90
Q

Function of silver nitrate:

A

The silver nitrate stick is considered an antimicrobial and is used in enhancing anti-inflammatory healing. A silver nitrate stick uses a chemical cautery agent made up of 75% silver nitrate and 25% potassium nitrate. When the tip of the applicator stick is moistened by wound fluid, a chemical reaction occurs: killing bacteria, removing necrotic tissue, reducing hypergranulation, reducing fibroblast proliferation, and coagulating tissue.

91
Q

Types of sharp debridement tools:

A

scalpel, curette, scissors, forceps

92
Q

Consideration of temperature regulation:

A

PT’S CORE BODY TEMP (necessary for wound healing): 91.4-107.6 for wound healing

-moisture loss= cooling

-degree change of 2 degrees affects healing
–> increase infection risk, inhibit platelet activation, reduction in wound strength due to decline in collagen deposition
