Study Notes
Types of Wounds
- Closed Wound: No break in the skin, often presents as swelling or bruise.
- Open Wound: Involves a break in skin or mucous membranes, includes abrasions, lacerations, punctures, and compound fractures.
Wound Categories
- Acute Wound: Heals quickly through the phases of inflammation, proliferation, and maturation.
- Chronic Wound: Exhibits long-term delayed healing; all chronic wounds are infected, such as pressure ulcers and diabetic ulcers.
Wound Cleanliness
- Clean Wound: Uninfected with minimal inflammation, can be either open or closed.
- Clean-Contaminated Wound: Surgical incisions into gastrointestinal, genitourinary, or respiratory tracts.
- Contaminated Wound: Major breaks in asepsis, high infection risk from sources like accidents or animal bites.
- Infected Wound: Positive culture or bacterial presence, manifests with signs of infection like increased pain or warmth.
Wound Classification by Thickness
- Superficial Wound: Limited to the epidermis, often due to shearing, friction, or burns.
- Partial-Thickness Wound: Extends through the epidermis into the dermis, but not fully through.
- Full Thickness Wound: Extends to subcutaneous tissue.
- Penetrating Wound: Involves visible bones, ligaments, tendons, or internal organs.
Specific Types of Wounds
- Abrasion: Scraping away the superficial skin layers.
- Abscess: Accumulation of pus from bacterial invasion.
- Contusion: A severe bruise resulting from trauma.
- Crushing Wound: Resulting from strong compressive force, may not break skin.
- Incision: Deliberate wound caused by sharp instruments.
- Laceration: Tissue torn with jagged margins.
- Puncture: Caused by sharp objects, increasing risk of infection.
Ulcers
- Arterial Ulcers: Round and dry, pale appearance due to inadequate blood circulation causing ischemia.
- Venous Ulcers: Wet and ruddy, associated with blood pooling and impaired circulation.
- Pressure Ulcer: Results from prolonged pressure causing tissue damage.
Pressure Ulcer Stages
- Stage I: Redness without blanching.
- Stage II: Partial thickness, extending through epidermis to dermis.
- Stage III: Full thickness, including subcutaneous tissue.
- Stage IV: Penetrating, exposing deep structures like bones and organs.
Healing Indicators
- Granulation Tissue: Appears beefy red, indicative of healing and new blood vessel formation.
- Epithelial Tissue: New epidermis, pink or pearly white, may form around a healing wound.
- Clean, Non-Granulating Tissue: Smooth, shiny appearance, indicates delayed healing.
Debridement and Skin Conditions
- Slough: Soft, stringy tissue requiring debridement.
- Eschar: Thick, leathery tissue that is dry, needs debridement.
- Maceration: Softening of surrounding skin from excessive moisture.
- Undermining: Skin around the wound feels mushy, indicating potential extension.
- Blistering: Fluid present under the skin.
- Crepitus: Trapped air under the skin, causing crackling sensation.
- Erythema & Swelling: Redness suggesting tissue risk of compromise.
