AEP Wound Healing Flashcards
What are the phases of wound healing (3)
- Inflammation
- Proliferation
- Remodeling
T/F: the phases of wound healing are exclusive events that occur in a reasonably predictable manner.
F: cascade of overlapping events that occur in a reasonably predictable manner
T/F: The phases of wound healing are the same for all wounds, open and closed, regardless of etiology.
True
What is the best dressing for a wound?
a semi-permiable dressing that allows oxygen in, but does not let moisture out
When does inflammation begin?
At the onset of injury.
T/F: In normal healing, there is a minimal manifestation of inflammation?
True
What do signs of excessive inflammation indicate?
Infection
T/F: Inflammation is essential for healing?
True
Inflammation is a reaction of what system?
Immune
Typically, how long does the inflammation phase last?
3-14 days
What is the purpose of inflammation? (3)
- Provides hemostasis
- Produces a clean wound site
- Brings in phagocytes
What are the main steps of inflammation? (3)
- Vasoconstriction
- Hypoxia
- Perfusion
Why does the vasoconstriction step of inflammation happen?
Clotting and vasoconstriction (hemostasis) occur immediately to reduce blood loss
What is the vasoconstriction step of inflammation mediated by?
NE
How long does vasoconstriction last during inflammation?
a few seconds to a few minutes
