Best Practices for Pressure Ulcers to Promote
Uncomplicated Healing
Introduction Pressure ulcers are major health problems
in the U.S. Affects approximately 1.3 to 3 million adults
yearly. Over 11 billion dollars is use to treat ulcers
per year.
Introduction (cont.) Increased awareness is important in the
health care setting to prevent ulcers. It is imperative to find the best research to
prevent and treat the occurrences of ulcers in the healthcare setting.
Sources We found 2 sources that were ranked high
on level of evidence that had comprehensive information.
The first source is a Retrospective cohort study with convenience sampling.
Sources (cont.) There were 4 themes that were examined in this
study: The relevance of nutrition to wound healing. Pressure ulcers cleaned with saline or soap
compared to those cleaned with other cleansers such as antiseptic, antibiotic, or commercial cleansers.
The therapeutic effectiveness of debridement on the wound bed.
Evaluating whether dry or moist dressings is more advantageous to healing.
Sources (cont.) Our second source is a clinical guideline.
We used this article to support the evidence found in our other source.
This clinical guideline identified the best practices for pressure ulcer management from 41 studies and articles related to pressure ulcer treatments.
Nutrition Nutrition is considered a significant factor in
both the prevention and treatment of pressure ulcers.
Protein, carbohydrates, vitamins, minerals, and trace elements are required for wound healing.
Nutrition A nutritional assessment
should be performed on all newly admitted patients and whenever there is a change in a patient condition.
Nutritional support should be given only to patients with identified nutritional deficiencies, and only when not contraindicated.
Infection Pressure ulcers need to be assessed and reassessed
for signs of infection. Infection complicates the healing process of pressure
ulcers. Early recognition along with prompt and effective
interventions is needed to address the infection. Assessment of the wound must be done to evaluate the
healing and the treatment of the wound.
Infection (cont.) Necrotic tissue must be removed and
present infection must be treated for healing to occur.
The necrotic tissue may be removed by different types of debridement.
Debridement Why is it needed for pressure ulcers?
To promote healing To allow the healing process to occur To protect against bacteria To remove dead tissue
Types of Debridement Enzymatic
Surgical
Autolytic
Mechanical
Debridement (cont.) Enzymatic debridement
Use of exogenous proteolytic enzymes to removed dead tissue.
Used in wounds with large amount of debris.
Advantages Minimal damage to healthy
tissue Bleeding disorders Very effective in most
patients Disadvantages
Expensive Topical agents Needs to be softened
Debridement (cont.) Surgical debridement
Removal of layers of necrotic tissue using a laser, scissors forceps, or curette using sterile technique.
Sharp debridement can be done by nurses with training.
Advantages Best used for larger
wounds and infected pressure ulcers.
Disadvantages Painful
EMLA cream as a local anesthetic
Costly Contraindicated in patient
receiving anticoagulants, and clotting disorders, lack of experience, sepsis
Debridement (cont.) Autolytic debridement
Stimulation of natural enzymatic activity by the use of the endogenous enzymes used to digest the dead tissue.
Used for larger pressure ulcers and deep wounds.
Semi-occlusive or occlusive dressing using transparent films, hydrocolloids, hydrogels
Advantage Selective Painless
Disadvantages Time Risk for infection
Debridement (cont.) Mechanical debridement
The removal of slough or necrotic tissue by use of wet-to-dry dressing or whirlpool treatment.
Used in wounds with a great amount of necrotic tissue.
Advantages Cost
Disadvantages Painful Takes off healthy tissue Trauma to wound Infection (whirlpool) Least recommended
Dressings Select the appropriate dressing for the wound
Consider the wound’s characteristics: location, phase of healing, infection, frequency of dressing changes, product availability, cost.
The choice of the dressing should change as the wound heals.
Moist wound dressings Advantages
Keeps the wound bed moist. Eliminates dead space. Controls the exudates.
Dressings (cont.) Nondraining Wounds
Use transparent film, hydrocolloid, or hydrogel dressings.
Draining Wounds Use foam, alginate, or
collagen dressings.
Dressings (cont.) Hydrocolloid dressings
Shown to have a lesser risk of infection than gauze dressings. Should not be used on infected wounds or wounds with
undermining, tunneling, or sinus tracts. Hydrocolloid dressings have a greater affect on wound healing
than saline gauze or paraffin gauze. Infected wounds
Do not use occlusive dressings when an anaerobic bacterial infection is present or suspected.
Positive correlation between gauze dressings and rates of infection, because they lower wound temperature and impede fluid evaporation.
