2. Bed Sores
• Decubitus ulcers or pressure ulcers
• It is an ulceration in the skin that is caused by
prolonged pressure on a bony or weight
bearing part of the body.
6. “ A bed sore ca develop in
as early as two to three
hours. In its early stage,
it usually appears as red
blotch on the skin which
is warm to touch...”
(Johnson & Johnson et
al)
7. Causes
Bedsores are accepted to be caused by three
different tissue forces:
• Pressure
There is compression of tissues. It leads to
decreased tissue perfusion, ischemia occurs
leading to tissue necrosis if left untreated
8. Causes
• Shear force
The force created when the skin of a patient
stays in one place as the deep fascia and
skeletal muscle slide down with gravity. This
can also lead to ischemia and tissue necrosis.
• Friction
It causes shedding of layers of epidermis.
9. Aggravating Factors
• Excess moisture
• Age
• Nutrition
• Vascular Diseases
• Diabetes mellitus
• Smoking
• Temperature: cutaneous metabolic demand rises
by 13% for every 1°C rise in cutaneous
temperature
10. National Pressure Ulcer Advisory Panel Classification
Stage 1
• the most superficial,
indicated by non blanchable
redness that does not
subside after pressure is
relieved.
• skin may be hotter or cooler
than normal, have an odd
texture, or perhaps be
painful to the patient.
11. National Pressure Ulcer Advisory Panel Classification
Stage 2
• Damage to the epidermis
extending into, but no
deeper than, the dermis.
• In this stage, the ulcer
may be referred to as a
blister or abrasion.
12. National Pressure Ulcer Advisory Panel Classification
Stage 3
• Damage to the epidermis
extending into, but no
deeper than, the dermis.
• In this stage, the ulcer
may be referred to as a
blister or abrasion
13. National Pressure Ulcer Advisory Panel Classification
Stage 4
• is the deepest,
extending into the
muscle, tendon or even
bone.
14. National Pressure Ulcer Advisory Panel Classification
Ustageable Pressure Ulcer
• Are covered with dead
cells, or eschar and
wound exudate, so the
depth cannot be
determined.
15. Braden Scale for Predicting Pressure Ulcer Risk
Six Criteria:
• Sensory Perception
• Moisture
• Activity
• Mobility
• Nutrition
• Friction and Shear
16. Braden Scale for Predicting Pressure Ulcer Risk
• Each category is rated on a scale of 1 to 4,
excluding the 'friction and shear' category
which is rated on a 1-3 scale.
• A score of 23 means there is no risk for
developing a pressure ulcer while the lowest
possible score of 6 points represents the
severest risk for developing a pressure ulcer
17. Treatment
Proper Care:
• The most important care for a patient with
bedsores is the relief of pressure.
• Once a bedsore is found, pressure should
immediately be lifted from the area and the
patient turned at least every two hours to
avoid aggravating the wound.
18. Treatment
Debridement
• Autolytic debridement - the use of moist
dressings to promote autolysis with the body's
own enzymes.
• Biological debridement, or maggot
debridement therapy, is the use of medical
maggots to feed on necrotic tissue and
therefore clean the wound of excess bacteria.
20. Treatment
• Chemical debridement, or enzymatic
debridement- the use of prescribed enzymes
that promote the removal of necrotic tissue.
• Mechanical debridement - the use of outside
force to remove dead tissue.
21. Treatment
• Sharp debridement - the removal of necrotic
tissue with a scalpel or similar instrument.
• Surgical debridement
• Ultrasound-assisted wound therapy- the use
of ultrasound waves to separate necrotic and
healthy tissue.
