Study Notes
Wound Healing Intentions
- Primary intention: Wounds with edges closely approximated, minimal tissue loss (e.g., surgical incision).
- Secondary intention: Open wounds with non-approximated edges, such as burns or trauma, require tissue replacement and take longer to heal with more scar tissue.
- Tertiary intention: Wounds left open initially to resolve infection or drainage and later closed.
Pressure Ulcers Stages
- Stage I: Intact skin with non-blanchable redness over bony prominences; may show changes in skin temperature or texture.
- Stage II: Partial thickness loss of dermis, presenting as a shallow, open ulcer or blister.
- Stage III: Full-thickness tissue loss with visible subcutaneous fat, potential undermining and tunneling.
- Stage IV: Full-thickness tissue loss with exposed bone, tendon, or muscle, often with slough or eschar present.
Wound Cleaning Techniques
- Cleaning wounds with approximated edges: Utilize sterile techniques, moisten gauze with cleansing agent, clean from top to bottom, working outward parallel to the incision.
- Cleaning wounds with unapproximated edges: Use sterile gauze or swab in circular motions from the center to the outside, extending cleaning beyond the wound margins.
Types of Wounds
- Incision: A cut with aligned edges, created by a sharp instrument.
- Contusion: Blunt force injury, skin intact, underlying tissue may bruise.
- Abrasion: Skin scraped off due to friction.
- Laceration: Tearing of skin, creating irregular edges and loose tissue.
- Puncture: Abrupt breach of skin by a sharp instrument, can be intentional or accidental.
Additional Concepts
- Pressure ulcers: Result from compromised circulation due to prolonged pressure or friction.
- Shearing: Tissue layers sliding over each other, often caused by improper lifting techniques.
- Dehiscence: Partial or total separation of wound layers, common in patients who are obese or malnourished.
- Avulsion: Deep tearing from its anatomical position, potentially exposing bones or blood vessels.
Dressings and Supports
- Gauze: Used for absorption of blood or drainage.
- Montgomery straps: Tape strips with eyelets for securing dressings that need frequent changes.
- Transparent dressings: Such as OpSite, primarily protect IV insertion sites.
- Hydrocolloid dressings: Examples include Duoderm and Tegasorb, promote a moist wound environment and provide cushioning.
