Transcript Pressure Ulcers

Zoya Minasyan, RN, MSN-Edu

A localized injury to the skin and/or
underlying tissue due to pressure with or
without shear/friction
Most common sites
▪ Sacrum
▪ Heels

Vascular disease
•Ulcers are graded or staged according to
deepest level of tissue damage
• A pressure ulcer may also present as a blood-filled blister.
• Stable (dry, adherent, intact) eschar on the heels serves as “the body’s natural
(biologic) cover” and should not be removed.
Intact skin with non-blanchable
redness
Possible indicators—Skin temperature,
tissue consistency, pain

May appear with red,
blue, or purple hues in
darker skin tones


Partial-thickness loss of dermis
Shallow open ulcer with red pink wound bed
Presents as an intact or ruptured serum-filled
blister

Full-thickness skin loss
involving damage or
necrosis of subcutaneous
tissue that may extend
down to, but not through,
underlying fascia


Presents as a deep crater
with possible undermining
of adjacent tissue
Depth of ulcer varies by
anatomic location.

Full-thickness loss can
extend to muscle, bone,
or supporting structures.
 Bone, tendon, or muscle
may be visible or palpable.

Undermining and
tunneling may also
occur.

Signs of infection

Leukocytosis
Fever
Increased ulcer size, odor, or drainage
Necrotic tissue
PainMost common complications
 Recurrence
 Cellulitis (is a inflammation of connective tissue with
severe inflammation of dermal and subcutaneous
layers of the skin)
 Chronic infection
 Osteomyelitis (an infection of the bone or bone
marrow)

Assess pressure ulcer risk on admission and at periodic
intervals based on care setting and patient’s condition.
Use risk assessment tools such as the Braden scale for
systematic skin inspection.
Look for areas of skin darker (purplish, brownish, bluish)
than surrounding skin.
Use natural or halogen light for accurate assessment
(fluorescent light casts a blue color that can skew results).
Assess skin temperature using your hand.
An ulceration may feel warm initially, then become cooler.
Touch the skin to feel its consistency.
 Boggy or edematous tissue may indicate a stage I pressure
ulcer.

Ask about pain or an itchy sensation.

Overall goals


No deterioration
Reduce contributing factors
Not develop an infection
Healing and no recurrence
Prevention is the best treatment.
 Identify risk factors and implement prevention strategies.

Remove excessive moisture.
Avoid massage over bony prominences.
Turn every 1 or 2 hours (with care to avoid shearing).
Use lift sheets.
Position with pillows or elbow and heel protectors.
Use specialty beds.
Cleanse skin if incontinence occurs.
 Use pads or briefs that are absorbent.
Caloric intake elevated to
30 to 35 cal/kg/day or
1.25 to 1.50 g protein/kg/day
 Supplements, enteral, or parenteral feedings may be necessary.
Document and describe size, stage, location,
exudate, infection, pain, and tissue appearance.
 Keep ulcer bed moist.
 Cleanse with nontoxic solutions.
 Debride.
 Use adhesive membrane, ointment, or wound
dressing.
 Verify good nutrition.
 Teach self-care and signs of breakdown.
 Initiate specialty services.
 Skin grafts

Objective Data: Physical examination-Inspection,
Palpation
Intertrigo. Rash in body folds with Candida infection.
Vitiligo. Total loss of pigment in the affected area.
Naevus of Ota. Flat gray to blue pigmentation in the upper trigeminal area, which is more
common in dark-skinned individuals.

straightening combs.
