Flashcards in Suture Deck (27):
What is the function of suture?
Hold tissue in apposition until wound healing progresses
What are the 4 properties of suture?
What is tensile strength?
How strong suture is and ability to resist breakage
The larger the suture size the ____the tensile strength
What is the weakest point of the suture?
The larger the diameter of suture the____ secure the knot
What are the length of suture tags?
3-5 mm internal
What is capilarity?
How much suture wicks/absorbs
What suture has high vs. low capilarity?
High: woven suture (vicryl)
Low: Monofilament steel
What type of tissue should vicryl not be used in?
What is the difference of absorbable and non-absorbable suture?
Absorbable: suture that has lost most of tensile strength by 60 d
Non-absorbable: Retains tensile strength longer than 60 d
What is the MOA of absorbable suture?
Hydrolysis and enzymatic
What suture absorbs much faster in acidic environment vs. alkaline environment?
What is the function of coated suture?
Decreases tissue drag
What type of coatings has less knot security?
Water soluble coating
What type of needle is used for tension relieving sutures in skin?
What is the most common used needle in SAM?
What is the most commonly used suture attachment?
Which needle is used for the intestine, SC and bladder?
What needle is used to dissect through friable tissue without cutting?
What needle has a cutting surface on the concave side?
What needle has a cutting surface on the convex side and is typically used for skin?
What are the two types of synthetic absorbable braided suture?
Vicryl and Dexon
Monocryl, caprosyn, biosyn, PDS and maxon are examples of what?
Monofilament synthetic absorbable
What are some adverse effects of cat gut suture?
Unpredictable enzymatic absorption
50% of this suture is absorbed at 6 months
