    Taper needle
  6. What needle is for external sutures or in areas of high resistance?
    Cutting needle
  7. What suture needle is used in external areas or on areas w/ resistance, but are less able to break or bend?
    Reverse cutting
  8. What type of animal has tough skin that may require the use of a reverse cutting needle?

    • Opposing edges of wounds/incisions
    • Obliterating dead space
    • Ligation
    • Tightening/stabilizing joints (cruciate ligaments)
    • Strengthening/replacing weakend tissue (Diaphragmatic hernia)
  10. What can a positive drawer sign indicate?
    ACL rupture
  11. What are treatments for ACL rupture?
    • TPLO (tibial plateau leveling osteotomy)

  13. Plain suture refers to?
    Suture not treated with anything
  14. Chromic suture refers to?
    Suture treated with acid salts that delay absorption rate
  15. Capillary refers to what?
    • Wicking
    • A suture materials ability to absorb liquids
  16. Monofilament suture tends to hold memory more so than multifilament suture.  What does this mean?
    It retains the shape of the package
  17. What is tensile strength?
    How much weight or pull the suture can withstand
  18. What can affect tensile strength?
    Tissue and enzymes
  19. What problem occurs more so with multifilament suture than monofilament?
    Wicking

    Decreases; increases
  21. Suture sizes range from _____ to ______
    10-O, 3
  22. When are absorbable sutures used?
    When prolonged strength is not required or when infection is present
  23. Non-absorbable suture is used when?
    Tissue rxn needs to be minimized or sutures are left in for more than 2 - 3 wks
  24. Surgical gut causes what type of reaction?
    Inflammatory due to absorption through phagocytosis
