Suture Materials Flashcards
How does the diameter of suture material work? Largest to smallest diameter
3, 2, 1, 0 ,2-0, 3-0
What are the 3 types of suture needles used?
- Taper
- Taper cut or point
- Cutting
- Reverse or Regular Cutting
- Blunt point
What are the 3 types of surgical needles
- Curved
- Straight
- Straight swaged
Monofilament vs. Multifilament suture
Monofilament:
- Single strand
- Less pliable and more susceptible to damage
Multifilament:
- Multiple braided or twisted strands
- Greater strength and pliability
- Increased tendency for bacterial colonization
- Avoid in contaminated wounds or where wicking of bacteria would be a problem
What are the 8 common absorbale sutures types
- Catgut
- Dexon
- Monocryl
- Vicryl
- Caprosyn
- PDS II
- Maxon
- Biosyn
What are the 8 common non-absorbale sutures types
- Nylon
- Polypropylene (Prolene)
- Silk
- Polybutester (Novafil)
- Polymerized caprolactam (Vetafil)
What are the 8 basic suture paterns
- Simple Interrupted
- Simple Continuous
- Vertical Mattress
- Horizontal Mattress
- Cruciate
- Ford Interlocking
- Continuous Subcuticular
- Continuous Horizontal Mattress
Define: Memory in terms of suture characteristics
Tendency for suture to return to its original shape
Define: Plasticity in terms of suture characteristics
Degree that suture will deform without breaking and maintain its shape
Define: Tensile Strength in terms of suture characteristics
Ability to resist deformation, breakage, and the stress at which deformation or breakage occurs
Define: Knot strength in terms of suture characteristics
Force necessary for knot to slip
Define: Capillarity in terms of suture characteristics
Degree of fluid transferred by the suture as a result of absorption
