Suturing Flashcards
What does tensile strength related to?
Suture size
Weight required to break a suture
What does knot strength mean?
Force required for a knot to slip
Configuration of Sutures
Monofilament
Braided multifilament
Benefit of a Monofilament
Less risk of infection
Benefit of Braided Multifilament
Easier to handle & tie
Define Elasticity
Degree suture stretches & returns to normal length
Memory or Suture Stiffness
High memory: suture stiff, difficult handling, unties
Tissue Reactivity with Sutures
Inflammatory response to suture
Peaks within 2-7 days
Define an Absorbable Suture
Suture breaks down over time in the body
Break Down of Suture Depends on
Type
Size: 0 takes longer than 8-0
