Wound Classification
Wound Classification
Cause: Determined by the origin of the wound.
Description of Skin Integrity: Overall assessment of skin condition.
Wound Depth (Thickness): Assessment of the tissue layers affected.
Presence of Infection: Evaluating if the wound is infected.
Chronic or Acute: Determining the ongoing nature of the wound.
Types of Wounds:
Open Wound: A break in the skin surface, includes;
Abrasion: Scraping of the skin.
Puncture: A pointed object pierces the skin.
Incision: A clean cut.
Closed Wound: The skin remains intact but there may be underlying damage, includes;
Bruising: Discoloration from bleeding under the skin.
Pressure-Related Injury: Damage from prolonged pressure.
Fractures: Break in the bone under the skin.
Note: Skin integrity does not indicate the severity of underlying damage.
Wound Depth
Categories of Wound Depth:
Superficial: Involves only the epidermis.
Partial Thickness: Involves the epidermis and part of the dermis.
Full Thickness: Extends through the subcutaneous layer, and may involve muscle and bone.
Assessment of Structures: Essential for understanding healing, scarring, and whether the wound is chronic.
Healing Process
Healing Process Types:
Primary Intention:
Tissue surfaces approximated (closed), with minimal or no tissue loss.
Characterized by quick healing and minimal scarring.
Secondary Intention:
Extensive tissue loss where edges cannot be approximated.
Longer repair time with greater scarring and increased susceptibility to infection.
Tertiary Intention:
Wound is initially left open to resolve issues such as edema or infection.
Closure occurs later with sutures, staples, or adhesive closures.
Phases of Wound Healing:
Inflammatory Phase: Initial response to injury, characterized by redness, swelling, and warmth.
Proliferative Phase: Involves granulation tissue formation and resurfacing.
Maturation Phase: Remodeling of tissue and scarring.
Nursing: Factors Affecting Wound Healing
Factors:
Oxygenation and Perfusion: Adequate blood supply is crucial for healing.
Diabetes: Can impair healing processes.
Nutrition: Essential for tissue repair and health.
Age: Older adults may experience slower healing.
Infection: Presence of infection complicates healing.
Complications of Wounds
Dehiscence: The surgical wound opens up after closure.
Evisceration: Protrusion of internal organs through the open wound.
Fistulas: Abnormal connections between two internal organs, or between an organ and the outside of the body, often leading to complications.
Skin Integrity - Burns
Types of Burns:
Superficial: Involves only the outer layer of skin.
Partial Thickness: Involves both the outer layer and part of the underlying layer.
Full Thickness: Extends deeper into tissues, possibly affecting muscle or bone.
Pressure Injuries
Definitions:
Decubitus Ulcer: A pressure ulcer which develops from prolonged pressure on the skin.
Pressure Ulcer: An injury to skin and underlying tissue as a result of prolonged pressure.
Prevention Strategies:
Identify risk factors and reduce pressure on bony prominences.
Improve tissue tolerance to pressure.
Ensure skin is dry, intact, protected, and perfused.
Adequate nutrition is necessary for skin health.
Causes of Pressure Injuries
Primary Cause: Pressure intensity and duration.
Other Contributing Factors:
Medical device-related injuries.
Friction and shear forces.
Sensory loss or immobility in patients.
Skin moisture, particularly moisture associated skin damage (MASD).
Nutritional factors.
Staging of Pressure Injuries
Stages of Pressure Injuries:
Stage 1: Intact skin with non-blanchable erythema.
Stage 2: Partial thickness skin loss involving the epidermis and/or dermis.
Stage 3: Full-thickness skin loss extending into the subcutaneous tissue; not affecting muscle or bone.
Stage 4: Full-thickness skin loss with damage and exposure to muscle, bone, or supporting structures, and elevated risk for osteomyelitis.
Other Classifications:
Unstageable: Eschar or slough that obstructs staging.
Suspected Deep-Tissue Pressure Injury: Intact skin with discoloration or blistering indicating deep tissue injury.
Notes: Healing pressure injuries will not regress or drop in staging criteria.
Assessment of Wounds
Factors to Assess:
The presence of risk factors for pressure ulcers.
Actual wound characteristics including;
Location
Size
Presence of undermining or tunneling
Type of drainage present
Edges and surrounding tissue quality
Condition of the wound bed
Patient's response to treatment.
Drainage Types:
Serous: Clear, watery fluid.
Serosanguineous: Mixed fluid containing blood and serum.
Sanguineous: Bloody drainage indicative of hemorrhage.
Purulent: Thick, yellow-green drainage indicative of infection.
Nursing Diagnoses Related to Skin Integrity
Common Nursing Diagnoses:
Impaired Skin Integrity: Documenting supporting data.
Impaired Tissue Integrity: Documenting supporting data.
Acute Pain: Documenting supporting data.
Planning and Goal Setting
Post-Diagnosis Planning:
Goals determined through collaboration with the patient, fostering mutual understanding.
Goals drive the selection of nursing interventions.
Interventions and Evaluation
Nursing Interventions:
Regular turning and positioning of patients.
Maintaining skin hygiene.
Utilizing pressure-reducing mattresses.
Wound cleansing and irrigation methods.
Performing debridement as necessary.
Appropriate dressing management, including the use of drains, sutures, bandages, and other closures.
Application of heat and cold as indicated.
Evaluation of Goals: Goals can be categorized as:
Met: Goals achieved as planned.
Partially Met: Some goals achieved, but not all.
Unmet: Goals not achieved, requiring reevaluation and adjustment of care.
