PRESSURE SORE
Pressure sores are localized areas of tissue breakdown in skin and/or underlying tissues that develop when persistent pressure between a bony site and underlying surface obstructs healthy capillary flow.
Constant external pressure over 70 mm Hg for 2 hours produces irreversible ischemic changes.
Synonyms : Pressure ulcer, Decubitus ulcer,
Bed sore.

Patient Populations at High Risk
Paraplegic or tetraplegic patients Patients with decreased sensation due to
neurologic disorders, e.g. stroke. Patients with impaired mental capacity. Seriously ill patients in an intensive care unit.
Additional Risk Factors Malnutrition Incontinence Tobacco use.

Pressure Sore Staging System
Stage I : Redness of intact skin that does not blanch.
Stage II : Partial-thickness skin loss involving the epidermis and dermis.
Stage III : Full-thickness skin loss involving the underlying subcutaneous fat but not the muscle.
Stage IV : Full-thickness skin loss with extensive destruction, tissue necrosis, or damage in muscle, bone, or supporting structures.

Treatment of STAGE I and II Pressure Sore
Keep the affected tissue clean and the surrounding area dry by regular daily dressing.
Apply antibiotic ointment (e.g., Bacitracin, silver sulfadiazine) daily to areas that have blistered.
![Page 8: Pressure sore management](https://reader034.fdocuments.us/reader034/viewer/2022042700/5560b1d3d8b42af93b8b46ba/html5/thumbnails/8.jpg)
Treatment of STAGE III and IV Pressure Sore
If the wound has a red, granulating base : Apply saline dressing daily.
If the wound contains necrotic tissue : - Surgical debridement is necessary. - Follow with daily dressings, using saline or EUSOL solution.
If the wound is infected : - Treat the patient with a course of
antibiotics. - Twice daily dressing with Betadine solution.

Wound Debridement When a wound is covered with black,
dead tissue or thick gray/green exudates, surgical removal of necrotic tissue is needed.
Dead bone or tendon in the wound must be removed.
Bleeding tissue is a good sign healthy tissue. Dead tissue does not bleed.
Once the necrotic tissue has been removed, regular Wet-to-dry dressing should be started.

Skin Grafting
Cross-section of human skin showing the epidermis, dermis and subcutaneous tissue.
The relative thickness of skin grafts is shown.

Split-thickness Skin Graft Indications :
• Large wound (> 5–6 cm in diameter) that would take many weeks to heal secondarily.
• Wounds that cannot be closed primarily.• Wounds that require more stable
coverage than scar.
Contraindications :• Malnourished patient.• Necrotic tissue or signs of infection at
the wound• A wound that has exposed tendon or
bone.

FLAP A flap is a piece of tissue with a blood
supply that can be used to cover an open wound.
A flap can be created from skin with its underlying subcutaneous tissue, fascia, or muscle.
![Page 22: Pressure sore management](https://reader034.fdocuments.us/reader034/viewer/2022042700/5560b1d3d8b42af93b8b46ba/html5/thumbnails/22.jpg)
Random Flaps Circulation to a
random flap is provided in a diffuse fashion through tiny vascular connections from the pedicle into the flap.
The pedicle must be bulky to increase the number of vascular connections.
The flap should not be longer than 3 times its width.
Random skin flap. The blood supply comes diffusely from the remaining skinattachment, which serves as the pedicle.

Different Types of Random Flaps
Rhomboid flap Rotation flap Tensor fascia lata (TFL) flap V-Y advancement flap. Rectangular advancement flap.

Rhomboid Flaps Rhomboid
flaps are useful for wounds up to 6 to 8cm in diameter on the trunk or extremity.
Useful in pressure sores with less surrounding tissue laxity.

Buttocks Rotation Flap Most
commonly used for sacral pressure sore.
Useful for sacral wounds about 10 to 12cm in diameter.

Tensor Fascia Lata (TFL) Flap
TFL flap is the most commonly used for closure of trochanteric pressure sore.
The flap is composed of the skin and fascial extension from the TFL muscle.

General Post Operative Care
Cleanse and apply antibiotic ointment to the suture lines daily.
If a suction drain was used, it should stay in place at least 1 week.
The patient should apply no pressure to the surgical site until the suture line has healed (usually 2–3 weeks).
Leave the skin sutures in place for at least 14 days unless there are signs of irritation from the sutures.

Failure of Flap surgery
Ischemic flap necrosis.
Infection.
