Prevention of pressure ulcers

Assess nutrition: albumin, CBC, hydration status, intake, weight, BMI. Supplement with high protein.



Position appropriately.

Braden scale

predicts ulcer risk

Wound exudate

Eschar: necrotic tissue.


Slough: yellow or white tissue that adheres to ulcer bed.


Granualation tissue: pink or beefy red tissue with shiny, moist, granular appearance.


Epithelial tissue: looks like new pink or shiny tissue that grows in from the edges.


Closed: new skin or epithelium

Debriedment stages

Hydrogels/Hydrocolloid dressings: Do not use with high exudate wounds. Can be used for many wound types: pressure ulcers, burns, macerated skin, fistula, stoma.


Granulation stage

Foam dressing works well with high-exudate wounds. Low adherence of foam dressing decreases wound trauma (dressing changes). Can be left in place for 3-4 days.


Tegaderm, Oposite


Wounds: leg ulcers, pressure ulcers, skin graft donor sites, minor burns, diabetic ulcers.



Epithelialization Stage

Hydrocolloid and low-adherance dressings are used.

Types of wound Dressings for Pressure Ulcers

Sharp Debridement

Tools: Scalpel or scissors and forceps


Gently lift negrotic tissue and cut it

Enzymatic Debridment

Topical proteolytic enzymes: Collagenase, fibrinolysin, deoxyribonuclease.


Apply to pressure ulcer

Autolytic debridement

Cover with hydrogel or semi-occlusive transparent film. Works better in wounds with little to no discharge.

Jet lavage

Water is used under pressure to clean and debride wound. A large syringe is connected to a short tube with a silicone needle tip.

Complications: Pressure ulcers

#1: Local infection (proteous miribilis, group D streptococci, E Coli, staph, pseudomonas, corynebacteriam organisms).


May spread to surrounding skin (cellulitis) or bone (osteomyelitis) and body (sepsis).


Superficial pressure ulcer infection treatmetn

Better wound care, debriedment.


No dine preps to ulcer wound because they impede healing.


Trial of topical antibiotics for 2 weeks (abx ointment or Silver sulfadiazine 1% cream)


Culture needs to be deep tissue specimen taken by wound biopsy or needle aspiration.

Osteomylitis

Refer for hospitalization for IVABX. Order plain xray- may need CD or MRI if positive xray.


Blood cultures, ESR, CRP, WBC, bone biopsy for C&S.

Marjolin Ulcer

Rare, malignant transformation of a chronic wound or scar. Very aggressive form of squamous cell carcinoma. Need a tissue biopsy from the ulcer and refer to Derm.

Wound healing

Primary: closure within 24 hours by sutures, glue, or adhesive strips.


Secondary: left open with formation of granulation tissue and scarring. Heals from bottom up. Edges are not well approximated.


Tertiary: heavy contaminated wounds or crush injuries are best left open to heal by secondary intention (granulation) and wound contraction. Then edges are approximated in 3-4 days.

High risk wounds

Infection (leave open for 24 hours, heals by secondary intention, abx - Keflex or Doxy)


Closed fist (ED for xray to rule out foreign body or fracture, test pulses, abx if animal bite: Augmentin, tetanus vac)


Facial


Foreign body (high risk of infection, needs xray)


Joint capsule


Electrical


Paint guns, high pressure wounds


Chemical


Abuse


Cartilage.
