Lecture By Dr.Tarik Alnojomi Emergency Medicine specialist. ER, Meeqat General Hospital

8. Causes of Skin Damage:
Pressure, Shear, Friction, Moisture
Examples of Friction:
Heels and elbows which aid in movement for
bedridden patients.
Agitated patients or those experiencing seizures.
Superficial abrasion or blistering

9. Shear and Friction

10. Causes of Skin Damage
Moisture:
.

11. Shear
Shear is the interaction of gravity and friction causing
twisting or kinking of blood vessels.
Shear occurs when the skeleton moves, but the skin
remains fixed to an external surface.

12. Examples of Shear:
Pulling patient up in bed
Patient in Fowler’s position who slides
down in bed
Slide patient from bed to stretcher.

13. Friction
Friction contributes to pressure ulcer formation
by damaging the skin at the epidermal-
dermal interface, the basement membrane.
Friction ulcers are generally superficial and
easily reversed, unless the cause is not
removed.

17. Factors Increasing Risk
Advanced Age : decreased elastic fibers.
More than 50% of pts with pressure sores >70
Decreased sensory perception
Peripheral Vascular Disease
Impaired Circulation
Edema
Vasoconstriction drugs
MI/ Stroke, Trauma/fractures
GI bleed

18. Equipment

19. Factors Increasing Risk
Equipment: pneumoboots
Spinal Cord injury: (Braces and stabilizing equipment)
Neurological disorders
Chronic medical conditions:
diabetes, COPD, CHF
History of pressure ulcers
If have stage I, 10X greater risk of developing higher stage
Preterm neonates
Obesity/ Thin: 30 >BMI< 19

20. Factors Increasing Risk
Critical Lab: Prealbumin level
(reflects Visceral Protein Stores)
Mild depletion = 10-15
Moderate depletion = 5-10
Severe depletion = < 5

21. Highest risk factors
 >70 years  stroke
 impaired mobility  pneumonia
 current smoking  CHF
 low BMI  fever
 altered mental state  sepsis
 urinary and fecal  hypotension
incontinence  dry and scaly skin
 malnutrition  history of pressure

 diabetes  lymphopenia
 hypoalbuminemia

22. ALL patients require a
R. A at Admission & every 24 hours.

23. Skin Safety: Risk Assessment
Reassessment:
Every 24 hours
(Pressure ulcers can develop within 24 hours
of insult or take as long as 5 days to
present.)
Change in condition
(surgery, nutrition, level of mobility, etc)

24. Braden Scale
 The Braden score is the total of the
subcategory scores.
 Sensory Perception

38. Presure Ulcer Staging
Stage I
Dark Skin

39. Pressure Ulcer Staging
Stage I

40. Presure Ulcer Staging
Stage II
• Stage 2: Partial thickness skin loss involving
epidermis, dermis, or both. The ulcer is
superficial and presents clinically as an
abrasion, blister, or shallow crater.

41. Pressure Ulcer Staging

Full thickness Stage III
involving damage to, or
necrosis of, subcutaneous
tissue that may extend down
to, but not through,
underlying fascia. The ulcer
presents clinically as a deep
crater with or without
undermining of adjacent
tissue.

46. Presure Ulcer Staging

48. Pressure Ulcer Staging
Stage IV
Full thickness skin loss
with extensive
destruction, tissue
necrosis, or damage to
muscle, bone, or
supporting structures
(e.g., tendon, joint,
capsule). Undermining
and sinus tracts also may
be associated with Stage
IV pressure ulcers

51. Stage IV

52. Stage IV

53. Unstageable/Unclassified:
The top layer of the sore is covered by
dead tissue, which may have a yellow, tan,
gray, green, or brown color. It may also
look like a scab. The dead tissue or scab
covers a deeper, more serious wound and
needs to be removed to be evaluated.

58. Assessment:
Assesses total skin condition at least twice a
day
Dry skin, Moist skin, Breaks in skin
Erythema
Blanching response
Warmth
Oozing & Odor
Evaluates level of Mobility
Restrictive devices
Peripheral Pulses, Edema.

60. Minimize pressure for All patients
 Consider pressure relieving devices:
 Special bed: Matrix mattresses and Bari-beds
 Z-flow positioning pillows
 Increase mobility and activity status whenever
possible.
 Minimally, turn patients every 2 hours
 Encourage weight shifting every
15 min in chair.
 Reposition every 1 hour if patient is
unable to do it themselves.

61. Mobility
*Use lifts and hovermats with
positioning.
Turn q 1-2 hours
Post turning schedule
Encourage ambulating
outside of the room
at least BID.

62. Moving and changing
position
• Help persons

63. • Skin Care
• Skin inspection daily at end of the shift, Look closely at
bony areas for redness or temperature changes.
• Wash skin with warm (not hot) water and use a mild
soap. This will reduce irritation and dryness.
• Apply lotion to keep the skin from Drying Out.
• Gently Massaging intact skin may help with
circulation and comfort. Avoid massaging bony
areas.
• Keep clothes and bed sheets dry. Protect the skin
from sweat and urine.

64. • Minimizing Friction and Shearing is also
important through Proper Repositioning,
Transferring, and Turning techniques.
Bed Sheets & Blankets are Dry and
Wrinkle-Free (smooth).
• Malnutrition should be treated
• Active and Passive range-of-motion

65. Moving and changing position

66. Moisture
Implement toileting schedule.
Cleanse skin gently
 Do not use hot water
 Apply skin barrier after each cleansing
 Protect skin with duoderm
Contain urine, stool, wound drainage, etc.
Keep skin folds dry.

67. Friction & Shear
 Use transfer devices
 Use minimum of 2 people + draw sheet
to pull pt up in bed.
 Don’t drag the patient
 Keep HOB at or < 30 degrees
 Use trapeze
 Pad skin surfaces (duoderm)
(elbows/heels)

69. Do not raise the head of the bed too high. .
Cause skin damage to the lower back and
buttocks areas.
Use a bed sheet or other device to help
move the person.
Do not allow the person to lie or sit on a
pressure ulcer. Move and change the
person’s position regularly.

70. Reassessment:
 Re-inspect and palpate ALL patients
every 8- 24 hours.
 Re-inspect when transferring between
units.
 Re-inspect after long procedures, ie:
dialysis, MRI’s, etc.

71. Pressure Ulcers are “mostly” Preventable
causes

Monitor Program
Weekly

74. Surgical intervention
 Débridement
 Incision and drainage
 Bone resection
 Skin grafting.

75.  Measure wounds upon admission and
weekly (or with significant changes).
 Note the location, size, depth, color of
wound bed and surrounding tissue and
describe the drainage.

76. Size:
 Measure length, width and depth of
wound.
 Measuring tools are available in unit
storerooms.
 Describe wound as a clock with
patient’s head at 12:00 and their feet at
6:00 to promote consistency in
descriptions.

77. Types of debridement
• Autolytic – (Occlusive Dressings) the body
heals itself
• Mechanical – using gauzes
• Enzymatic – chemical enzymes
(Collagenase, Papain, )
• Sharps – scalpel, laser, surgery
• Biosurgical – maggots, leeches
