Integumentary System Flashcards
What are the phases of wound healing?
Inflammatory (1-10 days)
Proliferative (3-21 days)
Maturation (7days - 2 years)
Inflammatory Phase
Initial immune system response to a wound. Temporary repair systems help restore homeostasis through platelets and clotting. Debris and necrotic tissue are removed.
Proliferation Phase
Formation of new tissue. Granulation tissue and capillaries fill the wound bed creating a new support structure. Epithelial cells begin to migrate. Skin integrity is restored.
Maturation Phase
Begins when granulation tissue and capillaries begin to fill wound bed. Formation of a scar and scar tissue.
What is Primary Intention?
Type of healing that occurs in acute wounds with minimal tissue loss. Wound is closed with sutures, staples, or adhesives. Superficial partial thickness wounds heal with primary intention.
What is Secondary Intention?
Type of healing that allows wounds to close on their own. Wounds with characteristics like significant tissue loss or necrosis, infections, and wounds that cannot be reapproximated all heal under secondary.
What is Tertiary Intention?
AKA delayed primary intention healing. Wounds at risk for developing complications like sepsis or dehiscence may be temporary left open.
