1- Wound Healing Flashcards
Name wound healing phases in order
1) inflammatory phase
2) debridement phase
3) Repair phase
4) maturation phase
Define vasodilation, which phase does this occur in
Dilation of blood vessels, brings inflammatory mediators to site
Inflammatory phase
Which phase?
Leakage of fibrinogen and clotting elements into wound. Formation of blood clots, scabs. Leakage of white blood cells into wound
Inflammatory
Define debridement
Removal of necrotic tissue, organisms, and debris at the cellular level
Define necrotic
Dead
Neutrophils and macrophages debride the wound by _______ of organisms, dead tissue, and debris. Which phase
Phagocytosis
Debridement phase
How long (ish) inflammatory phase
1-5 days
How long (ish) repair phase
3 days to 4 weeks
Which phase?
Fibroblast proliferation, capillary formation, collagen synthesis, formation of granulation tissue
Repair phase
Define granulation tissue
Fibrous connective tissue that grows in wounds and fills them. Delicate, moist, pink
Define epithelization
Formation of skin across wound, goes over granulation tissue
Maturation phase time estimate
17+ days
Which phase?
Wound strength increases due to collagen cross linking, #of capillaries in wound decrease, scar formation
Maturation phase
Older patients heal _____
Younger heal ______
(Fast/ slow)
Slow
Fast
Geriatric means
Old patient
