Skin Integrity and Wound Care
Importance of Skin Integrity
- The skin is the largest organ in the body, serving various functions to maintain health and protect from injury.
- Maintaining skin integrity is an important nursing function, and promoting wound healing is crucial.
Factors Affecting Skin Integrity
- Internal factors: genetic, age, and underlying health conditions
- External factors: activity, poor lifting and transferring techniques, incorrect positioning, and hard support surfaces
Types of Wounds
- Closed wounds: tissues traumatized without a break in the skin
- Open wounds: skin or mucous membrane surface is broken
- Classification of wounds based on contamination:
- Clean wounds: uninfected, minimal inflammation
- Clean-contaminated wounds: surgical wounds with minimal exposure to internal tracts
- Contaminated wounds: open, fresh, accidental wounds with evidence of inflammation
- Dirty or infected wounds: containing dead tissue or showing clinical infection signs
Specific Types of Wounds
- Incision: sharp instrument
- Contusion: blow from a blunt instrument
- Abrasion: surface scrape
- Puncture: penetration by a sharp instrument
- Laceration: tissues torn apart
- Penetrating wound: penetration of skin and underlying tissues
Risk Factors for Skin Breakdown and Delayed Healing
- Advanced age: changes in skin structure and function
- Chronic medical conditions: diabetes, cardiovascular disease
- Poor lifting and transferring techniques, incorrect positioning, and hard support surfaces
- Fecal and urinary incontinence: moisture promotes skin maceration and erosion
- Decreased mental status: less able to recognize and respond to pain
- Diminished sensation: paralysis, stroke, or neurologic disease
- Excessive body heat: increased metabolic rate, oxygen deficiency
