Surgical Wound
Show Answers:

  1. Pathogen
    Any virus, microorganism or other substance that causes disease
  2. Incision
    A cut produced surgically by a sharp instrument.
  3. Puncture
    Stab wound for a drainage system
  4. Hemostasis
    Termination of bleeding begins as soon as the injury occurs. Blood platelets adhere, a clot begins to form, fibrin begins to hold wound together and bleeding subsides.
  5. Inflammatory phase
    Initial increase in flow of blood elements and water out of the blood vessel into the vascular space causing erythema, heat, edema, pain, and tissue dysfunction cells in injured tissue migrate, divide, and form new cells. Sides of the wound usually meet in 24-48 hours. As this phase ends the wound begins to fill from underlying tissue to the skin surface.
  6. Primary Intention
    A would that has been made surgically and has little tissue loss; skin edges are close together and minimal scarring results.
  7. Secondary Intention
    Healing that occurs when skin edges of the wound are not close together (approximated) the wound must granulate or when pus is formed.
  8. Tertiary Intention
    Healing that occurs by primary intention with delayed suturing of a wound in which two layers of granulation tissue are sutured together.
  9. Purulent
    Producing or containing pus
  10. Exudate
    Fluid, cells or other substances that have been slowly exuded or discharged from cells or blood through small pores or breaks in cell membranes.
  11. Granulation
    Soft, pink fleshy projections consisting of capillaries surrounded by fibrous collagen that slowly fills the incision during process of healing.
  12. Venous stasis
    Stagnation of the blood or other fluids with a vein or to the veins
  13. Sanguineous
    Composed of or pertaining to blood.
  14. Serosanguineous
    Thin, red exudate composed of serum and blood.
  15. Serous
    Thin, watery exudate composed the serum portion of blood.
  16. Infectious process
    Condition caused by the invasion of the body by pathogenic microorganisms.
  17. Infectious process
    Condition caused by the invasion of the body by pathogenic microorganisms.
  18. Inflammatory response / cardinal signs & symptoms
    • A tissue reaction to injury
    • Erythema, Heat, Edema, Pain, Tissue dysfunction
  19. Asepsis
    Free of pathogenic microorganisms
  20. Gauze
    Permits air to reach wound.
  21. Semi-occlusive
    Permits oxygen but not air impurities
  22. Occlusive Dressing
    Permits neither air nor oxygen to pass.
  23. Irrigation
    Is gentle washing of an area with a stream of solution through an irrigating syringe.
  24. Signs of Hemorrhaging
    Increased thirst, restlessness, rapid, thready pulse, decreased blood pressure, decreased urinary output, and cool, clammy skin.
  25. Dehiscence
    When wound layers separate. Usually occurs between the 5 and 12 day postop.
  26. Evisceration
    When internal organs protrude through opened incision.
  27. What will the nurse do when evisceration occurs?
    Put in low fowler's with knees flexed keep pt. NPO, cover wound & content with warm, sterile saline dressing & notify surgeon asap.
  28. Signs of wound infection
    Purulent brown, yellow, or green drainage (pus) will have an odor, fever, tenderness and pain at the site, edema, elevated WBC
  29. Sutures
    Thread of wire or other material used to sew body tissue together.
  30. Types of sutures
    Are interrupted, continuous blanket or retention sutures (covered with rubber tubing) used primarily on obese patients and are removed after 14 days or more.
  31. Staples
    Made of stainless steal wire.
  32. Exudate
    Fluid, cells or other substances that have slowly exude or discharged from cells or blood vessels through small pores or breaks in cell membrane.
  33. Drainage
    The removal of fluids from a body cavity, wound or other source of discharge by one or more methods passively or with mechanical assistance.
  34. Closed Drainage
    Removes fluid in an airtight circuit that prevents environmental contaminants from entering
  35. Open Drainage
    Fluid passes through an open-ended tube into a receptacle or onto a dressing.
  36. Suction drainage
    Uses a pump or other mechanical device to extract a fluid
  37. Vacuum-assisted closure
    (Wound VAC) Device that assists wound closure by applying localized negative pressure to draw edges of wound together.
  38. Bandage
    A strip or roll of cloth or other material that can be wrapped around part of the body in a variety of ways for multiple purposes.
  39. Binder
    A bandage that is made of a large pieces of material to fit a specific body part. Most are made of elastic, cotton, muslin or flannel.
  40. Maceration
    Softening and breakdown of skin from prolonged exposure to moisture.
