Ch 32 Skin Intergrity Flashcards
Debridement
Cleaning away devitalized tissue and foreign matter from a wound
Bandage
Piece of gauze or other material used to cover a wound
Dehiscence
Separation of the layers of a surgical wound; may be partial superficial, or complete disruption of the surgical wound
Dermis
Layer of the skin below the epidermis
Desiccation
Dehydration; the process of being rendered free from moisture
Dressing
Protective covering placed over wound
Epidermis
Superficial layer of the skin
Eschar
A thick leathery scab or dry crust that is necrotic and must be removed for adequate healing to occur
Evisceration
Protrusion of viscera through an incision
Exudate
Fluid that accumulates in a wound; may contain serum, cellular debris , bacteria , and white blood cells
Fistula
An abnormal passage from an internal organ to the skin or from one internal organ to another
Friction
Occurs when two surfaces rub against each other; the resulting injury resembles an abrasion and can also damage superficial blood vessels directly under the skin
Granulation Tissues
New tissue that is pink/red in color and composed of fibroblasts and small blood vessels that fill an open wound when it starts to heal
Ischemia
Deficiency of blood in a particular area
Maceration
overhydration; of the skin related to urinary and fecal incontinence
-can lead to impaired skin integrity
Necrosis
Death of cells and tissue
Negative-pressure Wound Therapy (NPWT)
Activity that promotes wound healing and wound closure through the application of uniform negative pressure on the wound bed, but reduction in bacteria in the wound, and removal of excess wound fluid
Pressure Ulcer
Any lesion caused by unrelieved pressure that results in damage to underlying tissue
Wound
Purulent Drainage
Comprised of white blood cells, liquified dead tissues debris, and both dead and live bacteria
Serosanguineous Drainage
Mixture of serum and red blood cells
Scar
Connective tissue that fills a wound area
Serous Drainage
Composed of clear, serous portion of the blood and from serous membrane
Shear
Force created when layers of tissue move on one another
Results when one layer of tissue slides over another layer it separates the skin from underlying tissues
Subcutaneous Tissue
Underlying layer that anchors the skin layer to to the underlying tissues of the body
Wound
Injury that results I a disruption in the normal continuity of a body tissue
Peripheral
Pert. to or located at the periphery or away from the center. In anatomy and physiology, it refers to the outer part or surface of an organ or body or to the part of the nervous system outside the central nervous system or to the blood flow of the systemic circulation; in ophthalmology, to vision perceived near the outer edges of the retina.
Ecchymosis
Superficial bleeding under the skin or a mucous membrane; a bruise
Phases of Wound healing
- Hemostasis: sometimes concerned a part of the inflammation phase
- Inflammation
- Proliferation
- Maturation
Braden Scale
For predicting pressure sore risk it examines the skin
-sensory perception :ability to respond meaningfully to pressure related discomfort
- moisture : degrees to which skin is exposed to moisture
- activity : degree of physical activity
- mobility :ability to change and control body position
- nutrition :usual food intake pattern
- friction & shear
Serum
- A pale, watery fluid, esp. the fluid that moistens the surfaces of serous membranes.
- The watery portion of the blood after coagulation. It is the fluid found when clotted blood is left standing long enough for the clot to shrink.
- Serum obtained from blood that contains antibodies against a specific microorganism. It is used to provide immediate passive immunity.
Serous
- Having the nature of serum.
2. Thin or watery, rather than syrupy, thick, or viscous.
Effects of applying Cold
- constricts peripheral blood vessels
- reduces muscle spams
- promotes comfort
- reduces blood flow to tissues
- decrease local release of pain-producing substances like histamine, serotonin and bradykinin
- this action reduces edema and inflammation
Penrose Drain
Soft and flexible drain ; it does not have a collection device ; exits the skin through a stab wound or by the surgeon
