Suture Material & Needles Flashcards
Which suture type is considered “prolonged absorbable?”
Polydiaxonone (PDS)
What are the 5 types of non-absorbable suture?
Nylon, Silk, Polypropylene, Polymerized caprolactam, Stainless steel wire
This absorbable, multifilament suture type is broken down via phagocytosis, is made from collagen & submucosa of sheep intestine and is rarely used in practice. What is it?
Chromic gut.
This absorbable, multifilament, braided suture is coated with calcium sterate and is often used in dental surgery. What is it?
Polygalactin 910
This absorbable, multifilament, braided, synthetic suture type is formed by filaments from glycolic acid. comes in coated & uncoated forms and is often used in dental surgery. What is it?
Polyglycolic acid (PGA)
This absorbable, monofilament, synthetic suture type is polyester and has many uses including closure of enterotomies, cystotomies, body wall and fascia closure. What is it?
Glycomer 631 (BIOSYN)
This absorbable, monofilament suture type is broken down via hydrolysis, consisting of a single synthetic strand and is used in the closure of non-infected bladders & SQ tissues. What is it?
Caprolactone (MONOSWIFT)
This absorbable, monofilament suture type is composed of a copolymer of glycolide & epsilon caprolactone and is sued in closure of non-infect bladders and SQ tissues.
Poliglecaprone 25 (MONOCRYL)
This absorbable, monofilament suture type is uncoated and is considered ‘prolonged absorbable.” What is it?
Polydiaxanone (PDS)
This suture type is non-absorbable, multifilament, braided and often used in cardiovascular surgery. What is it?
Silk
This non-absorbable, monofilament suture is a polyamide based suture and is often used for skin closure. What is it?
Nylon
This non-absorbable, monofilament, synthetic suture is very resistant to degradation due to lack of hydrolyzable bonds and is used in tendon, ligament, fascial, & joint capsule closures. What is it?
Polypropylene
This non-absorbable, multifilament, nylon based suture is ONLY used for skin sutures. What is it?
Polymerized caprolactam (Vetafil Bengen)
What are the largest and smallest size sutures available?
Smallest = 12-0 Largest = 7
T/F: Tensile strength of suture in higher in larger suture.
True.
Smaller suture size = less tensile strength
T/F: Smooth suture is less traumatic to tissue, but has less knot security.
True.
What is capillarity?
Process by which fluid & bacterial are wicked along multifilament fibers.
All braided sutures have capillarity
T/F: Multifilament sutures should not be used in contaminated/infected wounds.
True.
How strong should suture be?
Sutures should be as strong as the tissue in which they are being placed.
What shape needle is most commonly used?
Half circle
What shape needle is used for ophthalmic procedures?
1/4 circle
What needle shape is the only shape to be manipulated with the fingers?
Straight
This needle point has a sharp tip that pierces & spreads tissues w/o cutting. What is it?
Taperpoint
This needle point has a cutting edge on convex surface, reducing risk of tissue cut out. What is it?
Reverse cutting
