Unit 2 Integumentary System Flashcards
Eschar
Dead, necrotic tissue
Purulent
Containing pus
Deep Tissue Injury
Purple or maroon localized area of discolored intact skin or blood filled blister due to damage of underlying soft tissue from pressure and/or shear.
Granulation Tissue
Also known as replacement tissue. It is red moist tissue composed of new blood vessels, that indicates healing. Happens in the proliferation phase and seats the skin up for epithelial tissue.
Necrotic Tissue
Death of living tissue , tissue is dark. Caused by infection, trauma, or toxin. Area of tissue become necrotic due to lack of blood supply.
Debridement needs to happen so the wound can heal and return to healthy granulation tissue.
Sloughing
The process of sloughing is slough being produced. Slough is yellow, white, brown, or green devitalized tissue, that can be stringy or thick and is adherent to the tissue.
Abrasion
Scraping or rubbing away of the upper layer of skin (epidermis) as a result of applied friction to skin.
Macerated
Softening of the skin from too much moisture. Very wet consistency and tissue will not heal in these conditions. Often pale in color.
Indurated skin
An increase in the fibrous elements in tissue commonly associated with inflammation and loss of elasticity
Skin becomes thick as a result from edema, inflammation, or infiltration.
Epithelization
The formation of granulated tissue in an open wound. Epithelial cells migrate across the new tissue to form a barrier between wound and environment.
Think resurfacing and closure of wound
Colonized
Presence of bacteria on a body surface or in the body without causing disease in the person.
Indurated Wound
Abnormal hardening or mass of the tissue formation around wound edges. It may be slightly raised.
Charcot Foot
Condition causing weakening of the bones in the foot that can occur due to significant nerve damage (neuropathy). Found in people with diabetes.
Autolysis
The destruction of cells or tissues by their own enzymes.
