Wound Care Flashcards
Debridement
cleaning away devitalized tissue and foreign matter from a wound
Dehiscence
separation of the layers of a surgical wound; may be partial, superficial, or a 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
a piece of material placed on a wound to protect it
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
removal of a drug from the body
Exudate
fluid that accumulates in a wound; may contain serum, cellular debris, bacteria, and white blood cells
Granulation Tissue
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 areas
Maceration
softening through liquid; over hydration
Necrosis
death of cells and tissue
Negative-Pressure Wound Therapy
activity that promotes wound healing and wound closure through the application of uniform negative pressure on the wound bed, reduction in bacteria in the wound, and the removal of excess wound fluid
Pressure Ulcer
any lesion caused by unrelieved pressure that results in damage to underlying tissue
Purulent Drainage
comprised of white blood cells, liquefied dead tissue debris, and both dead and live bacteria
Sanguineous Drainage
containing or mixed with blood
Scar
connective tissue that fills a wound
Serosanguineous Drainage
mixture of serum and red blood cells
Serous Drainage
composed of clear, serous portion of the blood and from serous membranes
Shear
an applied force or pressure exerted against the surface and layers of the skin as tissues slide in opposite but parallel planes
Sinus Tract of a wound
A tunneling wound or sinus tract is a narrow opening or passageway underneath the skin that can extend in any direction through soft tissue and results in dead space with potential forabscess formation.
Subcutaneous Tissue
underlying layer that anchors the skin layers to the underlying tissues of the body
Tunneling of the wound
A tunneling wound or sinus tract is a narrow opening or passageway underneath the skin that can extend in any direction through soft tissue and results in dead space with potential forabscess formation.
