When a flap of skin is torn away but still attached, aka degloving injury
What are the 3 phases of healing?
Inflammatory, proliferative, maturation
Healing phase that begins immediately after injury, platelets aggregate forming blood clot, and macrophages and neutrophils begin removing bacteria
The first 3-5 days after an injury are known as "lag phase" which occur during ______ phase
Occurs when surgical incision or wound reopens, most like occurs within 3-5 days or the ______ phase
This healing phase begins 2-3 days after injury and may continue for several weeks, overlaps inflammatory phase
When does granulation begin to fill a wound?
3-5 days after injury
Fibroblasts deposit ____ to strengthen the wound
Epithelialization begins ____ days over healthy granulation tissue
When does contraction of a wound begin?
Begins in 1 week
Phase begins at appx 3 weeks and can last weeks/months/years, collagen fibers form and fill the wound creating a scar
What is primary or first intention healing?
Clean, minor wounds. Tissues can be pulled togethr and sutured or stapled with no complication
Wounds older than 6-8 hours, treated as an open wound and then closed surgically. Closure must occur before granulation appears
Delayed primary closure
Healing when a wound is left open and allowed to heal from the inner areas to outer surface, results in scar formation
Wound is left open for 3-5 days to allow granulation tissue to form and then surgically repaired.
Combination of 1st and 2nd intention healing, open healing followed by closure.
3 considerations for wound management
