-
APPROXIMATION
Relating to the contact surfaces, either proximal or distal, of two adjacent teeth; proximate.
-
DEHISCENCE
premature "bursting" open of a wound along surgical suture
-
EVISCERATION
bowel contents protruding through the abdominal wall
-
- JP drain
- used to remove fluids that build up in areas of your body.
- Unwanted fluid can collect in areas of infection, areas where surgery has been done, or in other body areas.
- -squeezable football type reservior
-
TERTIARY INTENTION
- approach of having the patient return in 3-4 days,
- after initial wound cleansing and dressing, for wound closure.
-
PRIMARY INTENTION
wound closure immediately following the injury and prior to the formation of granulation tissue.
-
SECONDARY INTENTION
- strategy of allowing wounds to heal on their own
- without surgical closure.
-
EXUDATE
fluid with a high content of protein and cellular debris which has escaped from blood vessels during inflammatory phase, and is been deposited in tissues or on tissue surfaces.
usually as a result of inflammation.
-
-
PUS
- thick whitish-yellow fluid
- results from the accumulation of white blood cells (WBCs), liquified tissue and cellular debris.
-
SURGICAL ASEPSIS
- destruction of organisms before they enter the body.
- used in caring for open wounds and in surgical procedures
-
HEMOVAC DRAIN
- Round drain that is compressed flat to provide suction to a draining wound.
- -The capacity is larger (than a Jackson-Pratt)
- -Hemovac drain placed under skin during surgery.
- -This drain removes any blood or other fluids that might build up in this area.
- -has attached reservoir and is considered a CLOSED SYSTEM
- -looks like a manual air pump with springs
- -patient can go home with the drain still in place.
-
PENROSE DRAIN
- a thin rubber tube used as a surgical drain device.
- -Promoting drainage of blood, lymph, and other fluids helps reduce the risk of infection and keeps the patient more comfortable.
- -The penrose drain is the most commonly used drain.
- -drains directly onto the dressing and skin
**looks like a large flat piece of macaroni**
-
SLOUGH
- liquified necrotic (dead) tissue & wound byproducts
- -can be hard to distinguish from pus
-
SUPPURATION
formation of discharge or pus
-
STERILE
FREE from living organisms and especially microorganisms
-
GRANULATION
- Highly vascularised tissue that replaces the initial fibrin clot in a wound.
- *The tissue is also rich in fibroblasts (that will eventually produce the fibrous tissue) and leucocytes.
- --Tissue granulation in a wound bed is a positive sign because it indicates the wound is healing
- --Healthy granulation tissue is shiny, bleeds easily and appears beefy-red or deep pink. The surface of this type of tissue resembles raspberries
-
DEBRIDE
To remove dead, contaminated or adherent tissue or foreign material that may promote infection and impede healing.
-
HEMORRHAGE
Bleeding or the abnormal flow of blood
-
FISTULA
- an abnormal connection between an organ, vessel, or intestine and another organ, vessel or intestine, or the skin.
- --usually the result of trauma or surgery, but can also result from infection or inflammation.
-
SEROUS DRAINAGE
- consists of serum (from blood and mucous membranes)
- contains NO blood cells, platelets, or fibrinogen
- is clear and watery
- i.e. fluid in blister
-
SEROSANGUINOUS
- drainage fluid composed of both serum and blood
- -clear drainage, but blood tinged
-
ESCHAR
- dried, devitalized tissue
- prevents wound healing if allowed to accumulate
- cannot stage wound when present because you cant see it.
-
GRANULATION TISSUE
collagen-rich tissue which forms at the site of an injury.
-
EPITHELIALIZATION
the growth of epithelium over the surface of a wound, which marks the final stage of healing.
-
SANGUINOUS DRAINAGE
- bloody, seen in open wounds
- consists of large amounts of RBC's
- may be fresh (bright red) or old (dark red)
-
PURULENT DRAINAGE
- consists of PUS (liquified leukocytes and bacteria)
- varies in color (blue, green, yellow...)
- process of pus formation = suppuration
-
HEMOSTASIS
clotting of blood
-
EMACIATION
process of losing so much flesh as to become extremely thin; wasting
-
ERYTHEMA
Redness of the skin caused by dilatation and congestion of the capillaries, often a sign of inflammation or infection.
