IntroSx1- LA Suture

  1. What type of needle do you use for muscle/ fascial closure?
    taper needle
  2. What type of needle do we use for skin closure?
    • cutting needle!!!
    • S-curve or standard curved needles
  3. Describe the Buhner needle.
    • cutting needle with eye at point of needle
    • used for vaginal prolapse
  4. What are uses of Braunamid in LA sx?
    #3 for cattle skin (stronger than nylon)
  5. What are properties of Braunamid suture? (5)
    • non-absorbable
    • multifilament
    • reactive
    • easy handling
    • good knot security
  6. What are characteristics of polypropylene (prolene/ surgipro)? (4)
    non-absorbale, monofilament, high memory, poor knot security
  7. What are characteristics of polyester (ethibond/ tri-cron)? (4)
    non-absorbable, retains tensile strength, multifilament, reactive
  8. What are characteristics and uses of umbilical tape?
    • high capillarity, harbors infection, non-absorbable, doesn't cut through tissues
    • purse string sutures, temporary suture
  9. What are characteristics of chromic gut? (3)
    • absorbable by phagocytosis
    • relatively weak (low tensile strength)
    • multifilament
  10. What are uses of chromic gut? (3)
    • flank body wall closure
    • uterine closure
    • vessel ligations
  11. What are characteristics of polydioxanone (PDS)? (4)
    • prolonged absorbable by hydrolysis
    • monofilament
    • high memory
    • poor knot security
  12. What are characteristics of polyglyconate (Maxon)? (3)
    • [similar to PDS but better knot security]
    • monofilament
    • prolonged absorbable by hydrolysis
  13. What are properties of polyglactin (Vicryl)? (4)
    • multifilament
    • little memory
    • prolonged absorbable
    • high tensile strength initially, complete loss after 3 weeks
  14. What are characteristics of braided lactomer (Polysorb)? (4)
    • multifilament
    • little memory
    • good knot security
    • prolonged absorbable
  15. What are characteristics of Poliglecaprone (Monocryl)? (5)
    • absorbable¬†
    • high tensile strength initially, but rapid loss
    • monofilament
    • good knot security
    • minimal tissue reaction
  16. What type of suture do you use for linea closure? (2)
    vicryl, PDS (need high tensile strength b/c supports weight of abdomen)
  17. What sutures do you use for flank closure? (1)
    chromic gut #3 (high tensile strength not needed b/c doesn't support weight)
  18. What suture do you use for omentopexy?
    Chromic gut #3 (adhesion desired)
  19. What suture do you use for left flank abomasopexy (uncommon)?
    #3 braunamid (must be removed!! or will cause fistula)
  20. What suture do you use for uterine closure?
    chromic gut #2
  21. Always drive the needle __________ to the skin in LA closure and make sutures _______.
    perpendicular; tight (no skin swelling)
