Introduction

• Discussion on clinical experience and transition to the topic of pressure injuries.

  • Emphasized need for clinical practice as a crucial component of nursing education.

Pressure Injury Overview

• Pressure injuries, also known as pressure ulcers or bed sores, are serious concerns in hospital settings.

• Every pressure injury is preventable; nurses play a critical role in prevention.

• Importance of patient assessment regarding skin integrity and prevention strategies.

Risk Factors for Pressure Injury

• Immobility

  • Immobilized patients are at a heightened risk for pressure injuries.

  • Immobility significantly increases the chances of skin breakdown.

• Diabetes

  • Patients with diabetes can have neuropathy, leading to decreased sensation and increased risk for pressure injuries.

• Friction and Shearing

  • Friction: Rubbing of skin against surfaces (e.g., linen).

  • Example: Bed sheets can cause skin to rub and potentially break down skin integrity.

  • Shearing: Occurs when skin moves against a surface while the underlying tissue remains stationary; commonly seen when patients slide down in bed.

• Moisture

  • Incontinence or lack of proper hygiene can lead to skin breakdown due to constant exposure to moisture.

  • Hospitals usually refrain from using diapers to prevent such issues.

  • Frequent checks and moisture barrier ointments are essential.

• Nutrition

  • Malnourished individuals are at greater risk for skin breakdown, especially if they are NPO (nothing by mouth).

  • Enteral feeding may not provide all necessary nutrients, increasing risk.

• Additional risk factors include the use of medical devices (e.g., nasal cannulas, face masks, IV lines) and medical conditions affecting sensation or mobility.

Types of Pressure Injuries

• Pressure injuries develop in four stages, categorized primarily by the depth and characteristics of the injury:

  • Stage One:

  • Non-blanchable redness; skin is intact.

  • Redness may or may not be accompanied by discomfort.

  • Clinical management: offloading pressure areas and addressing moisture with barrier creams as needed.

  • Stage Two:

  • Partial thickness loss of skin; results in opened skin showing shallow, moist wound bed.

  • Blisters may also be classified as stage two.

  • Management: offloading, moisture control, and the use of transparent dressings.

  • Stage Three:

  • Full thickness tissue loss, with visible fat.

  • May include undermining and tunneling.

  • Management includes advanced dressings, possible debridement, and nutritional consultation.

  • Stage Four:

  • Deep wounds exposing bone, tendons, or muscle; highly complex management.

  • Management may require surgical intervention, potential skin grafting, and specialized care.

• Unstageable Wound:

  • Presence of slough or eschar makes it impossible to determine the depth.

  • Requires debridement for proper staging.

• Deep Tissue Injury (DTI):

  • Skin intact but shows dark maroon or purple discoloration; deeper tissue damage is implied.

Risk Assessment Tools

• Braden Scale:

  • Used to assess a patient's risk of developing pressure injuries.

  • Composed of six elements: sensory perception, moisture, activity, mobility, nutrition, and friction/shear.

  • Scores range from 6 (high risk) to 23 (low risk); higher scores indicate lower risk.

• Hendrich Fall Risk Model and Morse Fall Scale:

  • Used to evaluate a patient’s risk for falls.

  • Hendrich Scale: score of 5 or higher indicates increased fall risk.

  • Morse Scale: score over 25 indicates increased risk.

• Functional Assessments (e.g., Katz Index, Lawton IADLs) provide insights into patient's daily living capabilities, crucial for planning care.

Best Practices for Prevention

• Incorporation of turning schedules (every two hours) for at-risk patients.

• Utilization of specialized beds (with pressure redistribution features) and friction-reducing devices.

• Continuous education on proper assessments and preventive strategies to decrease incidences of pressure injuries in clinical settings.

• Early nutritional assessment and intervention, keeping albumin levels above 3.5 g/dL as a marker of nutritional status.

Patient Education and Engagement

• Importance of educating patients and family members about positioning and skin care to reduce the risk of pressure injuries.

• Engagement in the patient’s care plan; informing them of their roles in skin assessment and hygiene practices.

Documentation and Legalities in Pressure Injury Management

• Meticulous documentation of skin assessments: location, size, type, and progression of any pressure injuries.

• The impact of proper staging on reimbursement by Medicaid and Medicare emphasizes the need for accurate and timely assessments.

Wound Management Techniques

• Debridement:

  • Types include surgical and non-surgical methods to remove dead tissue from wounds.

  • Critical for healing, especially in deeper injuries (stages 3 and 4).

• Hydrogel Dressings:

  • Provides moisture to the wound bed; beneficial for various stages of healing.

• NPWT (Negative Pressure Wound Therapy):

  • Utilizes suction to promote granulation tissue, reduce swelling, and manage drainage in stage 3 and 4 wounds.

Common Wound Complications

• Infection: Signs include fever, pain, redness, and purulent discharge. Early recognition is vital for treatment.

• Dehiscence: Refers to separation of the edges of a wound; often prevents healing and increases risk of infection.

• Evisceration: Surgical emergency when internal organs protrude through a wound; necessitates immediate medical intervention.

• Fistula Formation: Abnormal connection between two organs; complications can arise from improper healing or infections.

Conclusion

• Continuous learning and improvement of wound care practices are essential for nursing professionals to manage risk effectively.

• Emphasis on the multi-dimensional approach to patient care, including immediate nursing interventions, patient education, and proper documentation of all assessments and interventions.
