Study Notes
Classification of Wounds
- Wounds are classified as clean, contaminated, sutured, or left open based on their healing process.
- Clean wounds: No interruption of respiratory, alimentary, genital, or urinary systems; no inflammation.
- Clean-contaminated wounds: Interruption of systems but no infection; example includes surgical wounds.
- Contaminated wounds: Major break in sterile technique or spillage of gastrointestinal contents; includes open, fresh, accidental wounds.
- Dirty or infected wounds: Show clinical infection signs like purulent drainage; commonly old accidental wounds.
Types of Healing
- Primary intention: Wound edges neatly approximated; healing occurs with inflammation, granulation, and maturation.
- Secondary intention: Wounds not sutured heal from the base, slower, larger scars may form, sometimes requiring skin grafts.
- Tertiary intention: Contaminated wounds left open initially and later sutured after infection control.
Phases of Healing
- Remodeling phase starts after about three weeks, lasting from 22 days up to one year; wounds contract slightly during this time.
- Inflammation phase lasts 3-5 days, involving blood clot formation and vessel constriction.
- Granulation phase begins around days 4-5 and continues up to four weeks, with fibroblasts and epithelial cells strengthening the wound.
- Maturation phase begins in week 2-3, lasting for several months, where scars become stronger and paler.
Signs and Complications of Wound Healing
- Six signs of infection include redness, warmth, induration, pain, abscess formation, and odor.
- Complications can arise at any stage of healing, mostly in the first week after surgery; they may occur at the surface incision or deep tissue.
- Complications include hypertrophic scars, keloids, contractures, dehiscence, evisceration, adhesions, and potential organ dysfunction.
Factors Affecting Healing
- Nutritional status, health conditions, age, obesity, diabetes mellitus, anemia, medications, and tissue trauma significantly impact wound healing.
Specific Terms
- Keloid: Scar resulting from excessive collagen production during healing.
- Dehiscence: Separation of surgical join, leading to potential complications.
