suture material Flashcards
which configuration is better suited for contaminated wounds?
monofilament–> can pass tissue more easily with little damage
which nonabsorable suture has least–>greatest tensile strength
least: natrual fibers (silk, cotton linen)
greatest: stainless steel wire
what degrades natural vs synthetic absorbable suture?
natural: lysosome
synthetic: hydrolysis
what are the synthetic multifilament, braided sutures?
polyglycolic acid and polyglactin 910
what is is polyglycolic acid used for
skin and subq
what are the synthetic, monofilament sutures
polydiaxonone, polyglyconate, poliglecaprone
when do synthetic absorbable sutures lose tensile strength
14 days once exposed to tissue fluid
what are non-absorbable sutures gen used for
skin repproximmation
which suture has highest suture reactivity but best handling property? and low tensile strength
silk-natural
what are the natural, non absorbable sutures
silk, cotton, linen
what are the synthetic, non-absorbable sutures?
nylon, polyester, polypropylene, stainless steel
which synthetic, nonabsorable can be used for for contaminated wounds?
nylon, polypropylene
which synthetic, non absorbable suture is typically used for tendon transfer or reapprox tendon after rupture
polyester
which synthetic, nonabsorbable suture is used for bone fixation and retention suture
stainless steel
what can polypropylene be used for
skin and subQ closure, and contaminated wounds
