Postop Terms Flashcards
Hypovolemic shock
Decrease in blood volume
Shock
A body’s reaction to acute peripheral circulatory failure as a result of an alteration in circulatory control or a loss of circulating fluid.
Atelectasis
Alveolar collapse, incomplete expansion of the lung.
Pneumonia
Inflammation or infection of the lungs
Hypostatic pulmonary congestion
Caused by weekend cardiovascular system that permits stagnation of secretions at lung bases.
PE
Blood clot that has dislodged from a vein and traveled to the lungs where it lodges in a pulmonary vessel.
Venous thromboembolism
PE and DVT together
Intentional wound
Planned invasive therapy or treatment. Risk of infection is decreased, healing is facilitated.
Unintentional wound
Accidental, trauma, gunshot, stab wound. Contamination is likely.
Open wound
Skin surface is broken providing a portal of entry for microorganisms. Bleeding, tissue damage, increased risk for infection, and delayed wound healing. Example: incisions or abrasions.
Closed wound
Skin surface is not broken but soft tissue is damaged and internal injury or hemorrhage may occur. Trauma like a blow, force or strained from a full, assault or motor vehicle accident. Example: hematoma.
Partial thickness wound
All or a portion of the dermis is intact.
Full thickness wound
Entire dermis, sweat glands, and hair follicles are severed.
Complex wound
Dermis and underlying subcutaneous fat tissue are damaged or destroyed.
Granulation tissue
Soft, pink, fleshy tissue, fragile and bleeds easily.
Process of wound healing:
1) primary or first intention healing
Wound edges are well approximated, granulation tissue is not visible, scar formation is minimal.
Process of wound healing:
2) secondary or second intention healing
Large open wound, edges not approximated, formation of granulation tissue, takes longer to heal, more scar tissue formed.
Process of wound healing:
3) tertiary or third intention healing
Wound is left open for several days to allow Edema or infection to resolve then it is closed. Deeper and wider scar results.
Negative nitrogen balance
When nitrogen intake is less than nitrogen excretion, there is a wasting and destruction of tissue.
Positive nitrogen balanced
When nitrogen intake (protein in food) is greater than excretion of nitrogen and urine/feces. this equals tissue formation and growth.
Clean wound
Non traumatic site, uninfected site, no break and aseptic technique, no entry into the respiratory, G.I., or genitourinary tract.
Clean-contaminated wound
Entry into the respiratory, G.I., or genitourinary tract, but no unusual contamination, minor brake and sterile technique.
Contaminated wound
Open, new traumatic wound, gross spillage from G.I. tract, major break and sterile technique, entry into the Genitourinary tract or biliary tract when urine or bile is infected.
Dirty wound
Traumatic wound with delayed repair, foreign body, or fecal contamination, acute or purulent drainage encountered during procedure.
