  1. What does the law state about LVT's suturing?
    closures performed upon a diagnosis and pursuant to direct orders from a vet
  2. We use aseptic technique to prevent ____ during suturing
    nosocomial infections
  3. Does the length of incision affect healing rate?  How does an incision heal?
    • no
    • heals side - to - side, not end - to - end
  4. What can blood clots and hematomas do to the healing process?
    prevents apposition of tissue and delays healing time
  5. How do we avoid tension on the sutured wound?
    use retention sutures placed parallel to the incision
  6. What happens if the suture is too loose?
    not apposed, delayed healing
  7. What happens if the suture is too tight?
    • strangulates tissue (blood can't flow to tissue)
    • suture breaks
    • suture cuts through tissue
  8. What is a "throw"?
    passing one strand of suture material over the other and pulling down
  9. What is a surgeon's knot?
    has an extra loop on the first throw
  10. Why do we do a surgeon's knot?
    to keep the suture from slipping
  11. How many throws should we do in order to secure a knot in synthetic suture material?
    four or five
  12. What is a granny knot?
    incorrect attempt at a square knot
  13. Why is it best to use instruments to tie knots?
    can work in "holes" and use less suture material
  14. How do we use instruments to tie knots?
    • only grasp the very ends of the suture, which will be cut off after the knot is formed
    • the part of the suture held with the instrument should not be included in the loop of suture or in the knot
  15. Why should we never use an instrument to hold a knot as it is being tightened?
    it will crush and weaken the suture and will make it more likely to break
  16. Where should the knot be on the suture?
    to the side of the incision
  17. What are the two general types of patterns?
    • interrupted suture patterns
    • continuous suture patterns
  18. Sutures should be placed with an ____ on each side of the incision
    equal bite
  19. Can we suture skin to skin?  SQ to SQ?  Muscle to muscle?  Skin to SQ?  Skin to muscle?
    • yes
    • yes
    • yes
    • no
    • no
  20. What is an interrupted pattern?
    the suture material is tied and cut after each stitch is placed
  21. What is the advantage to an interrupted pattern?
    if one suture breaks, the entire suture line will not open
  22. What is the disadvantage to an inerrupted pattern?
    • time-consuming
    • results in a greater bulk of suture material - may cause an increased inflammatory reaction
  23. Which patterns are interrupted?
    • simple interrupted
    • mattress sutures (horizontal and vertical)
    • cruciate stitch
  24. Out of the three interrupted patterns, which one will LVTs use the most?
    simple interrupted
  25. What is a continuous pattern?
    • uses running stitches to close the incision with knots placed only at the beginning and the end
    • place one or two extra throws on these knots
  26. What are the advantages to a continuous pattern?
    • takes less time to place
    • less bulk of suture material in patient's body to cause an inflammatory reaction
  27. What are the disadvantages to a continuous pattern?
    if one part of the suture material or knot breaks, the entire incision will become undone
  28. What are the different types of continuous patterns?
    • simple continuous
    • interlocking continuous
  29. Make your stitches as _____ and _____ as possible
    • regular
    • neat
  30. Who is going to judge you on the appearance of your suture line?
    the client
  31. Which direction should the needle point?
    towards yourself
  32. When we are tying a knot, how should we hold the suture material?  Why?
    • parallel to the surface
    • makes the knot form better and keeps the tension even on each end of the suture
  33. What instruments do you need to suture?
    • needle holders
    • thumb forceps
  34. How should you hold the needle holders?
    • hold in your dominant hand
    • first and fourth fingers in the finger rings
    • second and third finger to stabilize the shanks of the needle holder
  35. How should you hold the thumb forceps?
    hold in your non-dominant hand and held in a modified pencil grip (like the dental tools)
  36. Where should you grasp the needle with the needle holders?
    1/3 of the way from the swage or eye end to the tip
  37. Why should we not grap the tip of the needle with the needle holders?
    it will damage the tip and can be traumatic to the patient
  38. Why should we not grasp the joint between the swage end and the suture material?
    damages and breaks the suture
  39. Place the needle through the sking about _____ from the edge.
    5 mm
