Suture Materials and Patterns Flashcards
How long should sutures maintain their strength?
until wound has healed
do you use the smallest or largest size suture that will hold the tissue?
smallest
Define absorbable vs non-absorbable suture
absorbable - digested during wound healing
non-absorbable - retain strength for 60 days and remain in site
Characteristics - monofilament vs braided/multifilament
monofilament - induce less tissue rxn and capillarity braided/multifilament - may harbor bacteria and potentiate infection and/or suture sinus formation
which needled is swaged and which is non-swaged
which heals faster - visceral and superficial head wounds or distal limb?
visceral and superficial head wounds
which suture is absorbed more rapidly in face of infection?
chromic gut
what is the risk of suture in the bladder wall?
foreign body conductive to stone formation - use a small suture
what are the absorbable sutures?
vicryl, PDS, monocryl, gut/chromic gut/cat gut
what are the non-absorable sutures?
nylon/ethilon, prolene
Label parts of needle
Needle should enter and exit tissue same distances as _____________, perpendicular to the skin
Needle should enter and exit tissue same distances as skin’s thickness, perpendicular to the skin
Label the needle cuts
what needle point do you use for dense, thick, CT?
cutting
what needle do you use for abdominal viscera, CT, vessels, and other fragile tissues?
taper
define appositional
bring tissue in direct approximation of two cutting surfaces
define inverting
turns tissue edges inward
define everting
turn tissue edges outward
what type of suture pattern is this?
appositional
what type of suture pattern is this?
everting
what type of suture pattern is this?
inverting
what suture pattern is this? what is it used on?
cushing - inverting
large colon, urinary bladder and uterus
what suture pattern is this?
connell
which suture goes through the submucosa and which goes through the lumen?
submucosa - cushing
lumen - connel
which suture pattern is this?
utrecht - inverting
Bovine c-section
what suture pattern is this? what is it used on?
interrupted vertical mattress - everting
tension relieving
what type of suture pattern is this? what is it used on?
interrupted horizontal mattress - everting
tension relieving - best one
what type of suture pattern is this?
ford interlocking - appositional
when can ford interlocking suture pattern be used?
close skin in bovine C-section
what suture pattern is this? what is it used on?
near-far-far-near appositional
tension relief
which is a vertical mattress pattern and which is a horizontal mattress pattern?
