What does tensile strength related to?

Suture size
Weight required to break a suture

2

What does knot strength mean?

3

Configuration of Sutures

Monofilament
Braided multifilament

4

Benefit of a Monofilament

Less risk of infection

5

Benefit of Braided Multifilament

Easier to handle & tie

6

Define Elasticity

Degree suture stretches & returns to normal length

7

Memory or Suture Stiffness

High memory: suture stiff, difficult handling, unties

8

Tissue Reactivity with Sutures

Inflammatory response to suture
Peaks within 2-7 days

9

Define an Absorbable Suture

Suture breaks down over time in the body

36

Advantages of Adhesive vs. Sutures

Maximum bonding strength at 2:30
Equivalent in strength to healed tissued at 7 days
Applied using only topical anesthetic

Better acceptance by patients
Water-resistant covering
Does not require removal of sutures

37

Contraindications of Skin Adhesives

Bites, punctures, or crush wounds
Contaminated wounds
Mucosal surfaces
Axillae & perineum (high moisture areas)
Hands, feet, & joints (unless kept dry & immobilized)
