Suture Material and Needles Flashcards
Suture material that doesn’t need to be removed and is digested and assimilated by the body during normal healing
Made from animal or synthetic sources
Absorbable
Absorbable suture material that is produced from submucosal layers of sheep/hog intestines and is elastic and easy to handle
Plain and chromic
Surgical gut
What type of surgical gut absorbs within 3-5 days?
Plain
What type of surgical gut absorbs in 10-15 days and treated with acid salts to prolong absorption?
Chromic
Absorbable suture that is synthetic and made of hydroxyacetic acid and causes less rxn than gut
Lasts 14-21 days
Ex: Dexon, Kendall
Polyglycolic Acid
Degrades rapidly in an alkaline environment, dissolves faster in infected urine
Dexon and Vicryl
Absorbable suture that is made from lactic and glycolic acid that lasts about 14-21 days
Ex: Vicryl, Ethicon
Polyglactin 910
Absorbable suture made from glycoside/lactide copolymers and are multifilaments
Potential for bacterial wicking from braiding characteristics
Lasts 14-42 days, gone by 70
Ex: Kendall
Polysorb
Absorbable suture material made from newer synthetic polyester materials that has less tissue drags during placement and possesses memory
Better for slow healing wounds and lasts about 180 days
Used for dog spays
Ex: PDS, Ethicon
Polydioxanone/Polyglyconate
Absorbable suture material that is a monofilament and used where healing occurs more quickly
Used more commonly in replace of gut and lasts 7-14 days (gone by 90-120 days)
Used for cat spays
Ex: Monocryl, Ethicon, Biosyn, Kendall
Poliglecaprone and Glycomer 631
Least expensive absorbable material
Gut
What suture material can NOT be autoclaved?
Monocryl
Suture material that is not absorbed or digested by body tissue and remains in tissue until removed
Nonabsorbable
If nonabsorbable suture is left in tissue, it could become
encysted
When should nonabsorbable sutures be removed?
7-14 days post op
Pocket of serum from infx
seroma
Type of nonabsorbable suture that is commonly used with cardiovascular sx in humans and can induce tissue rxn in animals
Serves as a point of origin for infx
Silk
Type of nonabsorbable suture material that is made of natural fibers that increases in strength when wet
Limited use in vet med
Cotton and Linen
Type of nonabsorbable suture material that is synthetic polymerized plastic that doesn’t cause tissue rxn and can last for several years (stiff and slippery)
Has significant memory
Ex: Nylon, Ethicon
Polyamide
Type of nonabsorbable suture material of synthetic plastic similar to nylon
Doesn’t weaken over time and excellent for permanent suture support
Ex: Prolene, Ethicon, Surgipro, Ethicon, Flucrofil II
Polypropylene
Type of nonabsorbable suture material that is synthetic and more elastic (can stretch and return to original length without breaking)
Useful for repairing ligaments and structures under motion
Ex: Novafil, Kendall
Polybutester
Type of nonabsorbable suture material that is synthetic multifilament and requires 5-6 throws for knot security
Significant tissue drag and tissue rxn, can cause chronic infx and draining fistula
Ex: Mersiline, Tevdek, Polydek, Ethicon, Ti-cron, Kendall
Polyester Fibers
Type of nonabsorbable suture material made from synthetic fibers coated with plastic-like material
High tensile strength, minimal tissue rxn, and the outer sheath of suture can often break
Never be used below skin level (causes fistula and infections)
Polymerized Caprolactum
Nonabsorbable suture material made of stainless steel and useful for infx wounds or tissues that will be stressed in a slow healing process and pts that are active or have Hx of chewing out sutures
Can cause scarring and damage tissue
Can be autoclaved and is twisted instead of tied
Wire
