Suture Materials and Patterns

Question 1

How long should sutures maintain their strength?

Answer 1

until wound has healed

Question 2

do you use the smallest or largest size suture that will hold the tissue?

Answer 2

smallest

Question 3

Define absorbable vs non-absorbable suture

Answer 3

absorbable - digested during wound healing
non-absorbable - retain strength for 60 days and remain in site

Question 4

Characteristics - monofilament vs braided/multifilament

Answer 4

monofilament - induce less tissue rxn and capillarity braided/multifilament - may harbor bacteria and potentiate infection and/or suture sinus formation
