25
Dessicate
To dry out thoroughly
26
Dry gangrene
Dry, stable eschar
27
Edema
The presence of abnormally large amounts of fluid in the interstitial space
28
Epibole
Rolled edge of the wound margin due to reattachment of the skin to itself
29
Epidermis
The outer cellular layer of the skin (0.6mm)
30
Epithelialization
Regeneration of the epidermis across the wound surface
31
Erythema
Redness of the skin surface produced by vasodilatation
32
Eschar
Thick, leathery scab or dry crust composed of dead cells and dried plasma
33
Excoriation
Linear scratches on the skin
34
Exudate
A mixture of fluid, protein and cells in the wound
35
Fibroblast
Any cell from which connective tissue is developed
36
Friction
Surface damage caused by skin rubbing against another surface
37
Full-thickness
Tissue destruction extending through the dermis to involve the subcutaneous layer and possible muscle or bone
38
Granulation
The formation or growth of small blood vessels and connective tissue in a full- thickness wound.
39
Hemosiderin
Staining from iron rich pigment that is a product of red cell hemolysis
40
Hydrophilic
Attracting moisture
41
Hydrophobic
Repelling moisture
42
Hyperemia
Presence of excess blood in the vessels; engorgement
43
Infection
Overgrowth of microorganisms capable of tissue destruction and invasion accompanied by systemic symptoms
44
Inflammation
Defensive reaction to tissue injury; involves increased blood flow and capillary permeability and facilitates physiologic cleanup of the wound. Accompanied by increased heat, redness, swelling and pain in the affected area
45
Induration
Hardness at wound edges
46
Intermittent Claudication
Pain in lower extremities when walking short distances due to arterial insufficiency.
47
Ischemia
Loss of blood to an area due to constriction or obstruction of a blood vessel.
48
Leukocytosis
Increase in the number of leukocytes in the blood
49
Lymphedema
A condition in which extra lymph fluid builds up in tissues and causes swelling. It may occur in an arm or leg if lymph vessels are blocked, damaged, or removed by surgery
50
Maceration
Softening of the tissue caused by excessive moisture or soaking in fluids
51
Macrophage
Cells which have the ability to destroy bacteria and necrotic tissue
52
Necrotic
Dead; avascular.
53
Partial-thickness
Loss of epidermis and possible partial loss of dermis.
54
Periwound
Tissue surrounding a wound.
55
Prevalence
Prevalence measures all cases of a condition (e.g., pressure ulcers) among those at risk for developing the condition. Measures of prevalence are made at one point in time such as a specific day
56
Pressure ulcer
Area of localized tissue damage caused by ischemia due to pressure
57
Purulent
Thick fluid indicative of infection containing leukocytes, bacteria, and debris.
58
Sanguinous
Bloody drainage from a wound.
59
Serous
Fluid that has characteristics of serum; is clear
60
Serosanguinous
Fluid drainage with a bloody tint
61
Shear
Trauma caused by tissue layers sliding against each other resulting in disruption or angulation of blood vessels.
62
Sinus tract
Pathway extending in any direction from the wound and resulting in dead space with potential for abscess formation.
63
Slough
Loose, stringy necrotic tissue.
64
Tunneling
Pathway extending in any direction from the wound with an entry and exit point
65
Undermining
Tissue destruction underneath intact skin along wound margins
66
Wound base
Upper layer viable tissue in the wound; may be covered with slough or eschar
67
Wound margin
Rim or border of wound.
68
Wound repair
Healing process. Partial-thickness involves epithelialization; full-thickness involves granulation, epithelialization and contraction.
69
Wet gangrene
Boggy eschar, often a gray color.
