  1. Wound?
    Any tissue that has been damaged by either intentional/accidental means.
  2. Incision?
    Intentional cut of tissue for exposing/excising underlying structures.
  3. Excision?
    Removal of tissue.
  4. Closed wound?
    Skin is intact, but underlying tissue suffers damage.
  5. Class I?
    Clean; I.R: 1-5%; Uninfected; Primary union.
  6. Class II?
    Clean Contaminated; I.R: 8-11%; Under controlled circumstances; Primary union.
  7. Class III?
    Contaminated; I.R 15-20%; Open traumatic wound >4 hrs old; Major break in sterile technique; Acute inflammation.
  8. Class IV?
    Dirty/Infected; I.R 27-40%; Clinically infected wound/perforated viscera; Open traumatic wound <4hrs.
  9. Simple wound?
    Skin is destroyed, no loss/destruction of tissue & noforeign body in wound.
  10. Complicated wound?
    Tissue is lost/destroyed/a foreign body remains.
  11. Clean wound?
    Edges can be approximated & may heal by 1st intention.
  12. Contaminated wound?
    When dirty object damages the integrity of the skin, can become infected.
  13. Debridement?
    Excision of infected &/ necrosed tissue.

    Pain, heat, redness, swelling, loss of function.
  15. Name the types of wound healing and the a.k.a's:
    • (1) 1stintention (Primary Union)
    • (2) 2nd intention (Granulation)
    • (3) 3rd intention (Delayed Primary Closure).
  16. Name & describe the phases of 1st intention:
    • 1. Lag/ Inflammatory response phase; Begins within minutes.
    • 2. Proliferation phase; Fibroblasts secrete collagen that forms into fibers.
    • 3.Maturation/Differentiation Phase; undergoes slow sustained increase in tissue tensile strength.
  17. Describe 2nd intention;
    • Wound fails to heal by primary union, wound is left
    • open to heal from inner layer to the outside, wound cannot be approximated, may result in herniation.
  18. Keloid?
    Raised, thickened scar due to excessive collage.
  19. Proud flesh
    Excessive granulation.
  20. Described 3rd intention;
    heals by 2nd & 1st intention, typically classIII/IV surgical wounds.
  21. Dehiscene?
    Partial/total separation of layer/s of tissue after closure.
  22. Adhesion?
    Abnormal attachment of 2 surfaces/structures that are normally separated.
  23. Fistula?
    Tract between 2 epithelium-lined surfaces that is open at both ends.
  24. Sinus tract?
    Tract between 2 epithelium-lined surfaces that is open at oneend only.
  25. One-Layer Dressing?
    Used to cover a small incision from which drainage is expected to be minimal.
  26. Other types of one-layer dressings?
    Aerosol adhesive sprays, foams, gels, hydrocolloids, and skin closure takes.
  27. Nonocclusive?
    Allow passage of air & fluid.
  28. Intermediate layer?
    Absorbs any drainage/secretions.
  29. Gauge?
    Suture diameter.
  30. Size #5:
    Largest available suture.
  31. Size #1 & 0:
    Closure of ortho & abdominal fascia
  32. Size #4-0 & 5-0:
    Aortic Anastomosis
  33. Size #6-0 & 7-0:
    Smaller anastomosis
  34. Size #8-0 through 11-0:
    Micro vascular & eye procedures
  35. Size #4-0:
    Dural incisions
  36. Size #3-0 & 4-0:

  39. Vicryl and Dexon are what kind of sutures?
    Multifilament Absorbable Sutures
  40. Rapid released needles are a.k.a?
