IntroSx1- Suture Patterns

  1. What are the 3 components to ideal wound closure technique?
    • tensile strength maintained throughout the healing process
    • technically simple and quick for the surgeon to perform
    • allow for precise wound edge apposition
  2. ___________ is inversely proportional to the wound closure tension, which affects ___________.
    Blood supply to the wound edge; healing
  3. Why shouldn't you dissect subQ in small animals?
    the vascular supply is superficial, middle, and deep plexuses; there is only one blood supply to the SQ--> dissecting below the SQ can severely compromise blood supply to the wound edges
  4. Wound healing occurs by ____________, and the wound may have a(n) _________ by ________ post-sx if... (3)
    epithelialization; epithelial seal; 24 hours; there is ideal apposition of SQ, dermis, and epidermis.
  5. What appositional patterns do we use in vet med? (4)
    simple interrupted and continuous, cruciate, ford interlocking, interrupted and continuous intradermal
  6. What patterns will we use to close each body wall layer in vet school?
    • linea alba- simple interrupted
    • SQ- simple continuous
    • epidermis- cruciate (intradermal in shelter)
  7. Why is cruciate often chose for skin closure?
    stronger than simple interrupted, prevents eversion
  8. How do you bury the knot at the beginning of a suture line? At the end?
    • Beginning: deep to superficial on near side; then superficial to deep on far side; tie parallel to incision
    • End: Loop 1 is superficial to deep on far side; loop 2 is superficial to deep on far side, tightened; free end should point toward opposite end of incision and be deep
  9. What is the name of the suture pattern use with intradermal closure?
    buried knots with horizontal mattress
  10. What inverting suture patterns do we use? (3)
    cushing, lembert, purse-string
  11. When do we use inverting suture patterns?
    hollow organs with a large lumen (bladder, uterus, stomach)
  12. Describe the cushing suture pattern.
    partial thickness bites taken parallel to incision line; creates tissue inversion with a watertight seal
  13. Describe the lembert suture pattern.
    partial-thickness bites perpendicular to incision line; far-near--> near-far
  14. What is the purse string suture pattern, and when is it used?
    circular variation of continuous lembert; used to temporarily close orifices, tubes, drains, biopsy sites
  15. What are the everting suture patterns? (2)
    horizontal and vertical mattress
  16. Describe the horizontal mattress suture pattern.
    suture parallel to incision line--> cross incision--> parallel to incision line--> cross incision--> so on
  17. When do we use horizontal mattress? (3)
    areas of high tension (such as joints), step defects (after mastectomy, suturing thick lateral skin to thin ventral skin), underlay mesh
  18. What are disadvantages to horizontal mattress? (2)
    can compromise blood supply, can cause eversion
  19. Describe the vertical mattress suture pattern.
    far--> far-near--> near perpendicular to incision
  20. When is vertical mattress used? (3)
    resist tension, stretch skin, mesh application
  21. What is an advantage of vertical mattress over horizontal mattress?
    vertical allows better blood flow
