Study Notes
Stage 1 Pressure Injuries
- Characterized by nonblanchable erythema (redness that doesn't fade when pressed)
- Skin remains intact
- Treatment includes cleansing, barrier cream, protective dressing, pressure redistribution, and frequent repositioning
Stage 2 Pressure Injuries
- Involve partial-thickness loss of dermis, resulting in a shallow open wound or blister
- Treatment includes cleansing, moisture-retaining dressing, assessment for necrosis and infection, frequent repositioning, and comfort measures
Stages 3, 4, and Unstageable Pressure Injuries
- Involve full-thickness tissue loss, exposing underlying bone, muscle, or support structure
- May have slough or eschar present
- Treatment includes cleansing, debridement, surgical removal of necrotic tissue, medicated moisture-retaining dressing, assessment and treatment of infection, pain management
Deep Tissue Pressure Injury
- Characterized by localized purple discoloration, potentially leading to a thin blister or eschar
- Skin remains intact
- Treatment includes cleansing, moisturizers or barrier creams, nonadhesive protective dressing, pressure removal, elevation, and monitoring for pressure injury development
Stage 1 Pressure Injury
- Stage 1 pressure injuries are characterized by nonblanchable erythema of intact skin.
- This is the earliest sign of skin ulceration.
- Stage 1 pressure injuries commonly occur over bony prominences.
- The affected area might be painful, have a different temperature, and feel different in consistency compared to the surrounding skin.
- Identifying Stage 1 pressure injuries can be challenging in individuals with darker skin tones.
Deep Tissue Pressure Injury
- Defined by intact or nonintact skin with a localized, nonblanchable maroon, deep red, or purple discoloration.
- May also present as a blood-filled blister.
- Indicates underlying soft tissue damage due to pressure or shear forces.
- These injuries can evolve quickly into thin blisters over dark wound beds or develop thin eschar.
- Difficult to detect in individuals with darker skin tones.
- May be preceded by painful tissue that is a different temperature and consistency from surrounding skin.
Pressure Injuries: Prevention and Management
- The primary focus for patients at risk of pressure injuries is prevention.
- Regular assessments and repositioning according to a schedule are crucial.
- Proper repositioning technique is essential to prevent shear injuries.
- Regular assessments of existing ulcers are vital to prevent progression to more severe stages.
- Patient and family education on ulcer protection, treatment, and stage assessment is key.
Diagnostic Tests for Pressure Injuries
- Diagnostic tests are employed to identify secondary infections and differentiate the root cause of pressure injuries.
- White blood cell (WBC) counts measure inflammation or invasive infection.
- Erythrocyte sedimentation rate (ESR) evaluation helps determine the presence of osteomyelitis.
- Nutritional parameters, like albumin, prealbumin, transferrin, and serum protein levels, assess the patient's nutritional status, which is vital for wound healing.
- Additional laboratory studies, including urine, stool, or blood cultures, may be required based on individual patient needs.
- For deep or infected pressure injuries, drainage or biopsied tissue is cultured to identify the causative organism.
Wound Debridement
- Nonviable tissue must be removed from a wound before it can be staged or heal.
- Surgical debridement, the removal of necrotic material, may be necessary for deep pressure injuries, subcutaneous tissue involvement, or when eschar has formed.
- Autolytic debridement, the breakdown of damaged tissue by the body's own enzymes, is another method used to treat pressure injuries.
- Autolytic debridement uses dressings like hydrocolloids, alginates, hydrogels, and transparent films to maintain moisture and support the body's natural enzymes in debriding wounds.
- This method is slower than other techniques but more selective, causing less damage to healthy tissue.
- Larval Therapy using maggots, specifically Phaenicia sericata, is regaining popularity due to their antimicrobial and growth-promoting activity.
- Maggots have been historically recognized for their effectiveness in debridement, as they secrete and excrete digestive enzymes that break down necrotic tissue while leaving healthy tissue untouched.
- Research indicates these larvae also secrete and excrete antimicrobial compounds, reducing bacterial growth and contributing to the healing process.
- The maggots' physical movements stimulate the development of granulation tissue.
- Skin grafting may be required for the complete closure of large wounds.
Wound Debridement
- Nonviable tissue must be removed before a wound can heal or be staged.
- Surgical debridement removes necrotic material and may be required for deep wounds, wounds involving subcutaneous tissues, or wounds with eschar.
- Autolytic debridement uses the body's enzymes to break down damaged tissue.
- Dressings containing hydrocolloids, alginates, hydrogels, and transparent films support autolytic debridement by maintaining moisture.
- Autolytic debridement is the most selective method and causes minimal damage to healthy tissues, but it takes longer than other debridement methods.
- Fly larvae therapy is effective in debridement due to the larvae's ability to secrete digestive enzymes that break down necrotic tissue while leaving healthy tissues untouched.
- Fly larvae also secrete antimicrobial compounds, reduce bacterial growth, and stimulate granulation tissue development.
- Large wounds may require skin grafting for closure.
Pharmacologic Therapy
- Topical and systemic antibiotics target specific infectious organisms to eradicate any infection.
- Topical products promote healing.
- Hydrocolloid and transparent film dressings are typically used for clean, granulating pressure injuries and maintain moisture, protect from friction and bacterial colonization.
- Dressings impregnated with silver sulfadiazine and medical-grade honey offer microbial benefits.
- Deep, exudative wounds may benefit from alginate, foam, and iodine dressings.
- Dressing selection can change over time as the wound heals or worsens.
- Common dressing types include hydrocolloid, alginate, hydrogel, transparent adhesive, and vacuum-assisted sponge.
Nonpharmacologic Therapy
- Pressure injuries present challenges for nurses due to numerous variables, including risk factors, ulcer types, impairment levels, and diverse treatment measures.
- Infection is the most serious complication of pressure injuries.
- Nurses should adhere to agency protocols and healthcare provider orders when treating pressure injuries.
- Prompt treatment can prevent further tissue damage, reduce pain, and facilitate wound healing.
