Stable
Permanent
Term
List 4 steps involved with scar formation:
Definition
- angiogenesis: new blood vessels with numerous capilaries
- area becomes cellular: fibroblasts and mononuclear chronic inflammatory cells come around
- fibroblasts synthesize collagen to form fibrous scar
- collagen turnover for maturation and shaping of scar
Term
clean surgical wounds with apposed margins heal by ___ ____.
Definition
primary intention
Term
Steps of primary intention:
Definition
- scab forms from the blood in the defect, composed of fibrin meshwork
- macrophages phagocytize and secrete proteins to stimulate angiogenesis and collagen synthesis
- cells regenerate at the skin surface
- fibrous union with collagen
- scar maturation
Term
Large gaping, infected wounds heal by ___ ____. With this method, there are more ___ ___, especially ___ if infected. There is more ___ tissue. And wound ___ occurs by ____ to bring the margins of the wound together.
Definition
- secondary intention
- inflammatory cells
- PMNs
- granulation
- contraction
- myofibroblasts
Term
with secondary intention, the ___ cells cannot restore the architecture so there is more ____ tissue to fill in the wound.
Definition
parenchymal cells aren't enough
granulation tissue
Term
initial phase of wound contraction involves ___ ____ ____ at the edge of the wound. Permanent wound contraction requires ____.
Definition
-actin-containing fibroblasts
- myofibroblasts
Term
secondary intention wounds contain more ___ and ___tissue.
Definition
granulation and fibrous
Term
wounds healed by secondary intention:
Definition
Require more time to close because the edges are far apart
Show a more prominent inflammatory reaction in and around the wound
Contain more granulation tissue inside the tissue defect
Term
what is the single most imoportant delay in wound healing b/c it results in persistent tissue injury and inflammation.
Definition
infection
Term
foriegn bodies,even sutures, can impede healing
Definition
Term
wounds in highly vascularized areas like the ___ heal faster then wounds in poorly vascularized areas like the ___.
Definition
face
feet
Term
the most common pathogen causing infection with wound healing:
Definition
Staphylococcus aureus

community acquired methicillin resistant staphylococcus aureus
Term
___ and __ __ deficiencies can also cause poor wound healing.
Definition
protein
vitamin C
Term
Excess ____ interfere with collagen formation and decrease tensile strength with wound healing.
Definition
corticosteroids
Term
in healing a skin ulcer what are 2 important growth factors:
Definition
basic fibroblast growth factor
vascular endothelial growth factor
Term
acuummulation of excessive amounts of collagen leads to a ___ scar. If it grows outside of boundaries of original injury it is a __ scar
Definition
hypertrophic
keloid
Term
inadequate formation of granulation tissue or assembly of scar can lead to two types of complications:
Definition
1. Dehiscence or rupture of a wound is most common after abdominal surgery and is due to increased abdominal pressure
2. ulceration
Term
___ tissue is required for normal connective tissue repair.
Definition
granulation
Term
wounds can ulcerate b/c of inadequate ____ during healilng.
Definition
vascularization

seen with lower extremity wounds in pple with atherosclerotic peripheral vascular disease
Term
___ is the major fibrous component of connective tissue. ___ __ is required in ___ reactions in collagen synthesis.
Definition
- Collagen
- Ascorbic acid
- hydroxylation
Term
Ascorbic acid hydroxylates ___ and ___ in collagen synthesis.
Definition
proline
lysine
Term
Cross-linking increases the overall tensile strength of collagen (also elastic tissue).
Decreased cross-linking (e.g., vitamin C deficiency) reduces the tensile strength of collagen.
In vitamin C deficiency, the structurally weakened collagen is responsible for a bleeding diathesis (e.g., bleeding into skin and joints) and poor wound healing
Definition
Term
Ehlers Danlos syndrome (EDS):
Definition
defects in type I and III collagen
Term
Zinc is a cofactor in ____ ____ in wound remodeling, deficiency leads to poor wound healing.
Definition
- metalloenzyme collagenase
Term
___ and __ ___ deficiencies lead to decreased cross linking in collagen and poor wound healing.
Definition
copper and vitamin C
Term
The majority of patients undergoing amputation of the lower limb have peripheral vascular disease, often resulting in significant morbidity and mortality. The incidence of amputations is higher in smokers, rises with age and is higher in men than women, and patients with diabetes
