What is Tensile strength, Uniformity, Capillary action?
What are the handling qualities of suture?
What is compliance, memory, plasticity, and bioactivity?
Suture size is based on
What is the diameter of a single strand?
What is monofilament?
what is a single continuous fiber made by extruding and stretching synthetic material?
What is the range of size for suture?
What is 11-0 to 5?
What is tensile strength?
What is the amount of force needed to break the suture?
What is Compliance/Pliability?
What is the ease of handling or softness of the suture?
Makes it easier to manipulate and tie down
Silk- gold standard for pliability
What are materials suture is made from?
What is synthesized chemicals, animal proteien, metal, natural fibers?
What is multifilament?
What is a many fibers together from one strand of suture?
Sutures ________________ than 0 are designated by
____________________ 0s.
What is smaller and additional?
What does uniformity mean?
What is a uniform diameter to maintain tensile strength?
What is memory?
What is the suture's tendency to retain its original shape or configuration after it is removed from the package?
High memory suture is springy and tends to tangle during preparation and use.

packaging, dyes, integrity of the needles?
What are 2 types of multifilament suture? Define the 2.
What is twisted and braided?
Twisted-multiple fibers twisted in the same direction
Braided- multiple fibers are intertwined.
Stainless steel suture numbers begin with ________ and go up to __________
what is 38/40 to 18?
What is capillary action/wicking?
What is sutures made of multifilament strands that absorb moisture and hold body fluids.
What is plasticity?
What is the suture materials ability to stretch and retain a new shape?
What are some advanced features of suture in the wound healing process?
What is antibacterial substances, one-way barbs, anchoring devices, coating to ensure smooth passages, staple line reinforcement, incision adhesive?
What is composite or coated?
What is a core strand of one suture material jacketed with another or different or the same type?
What guage stainless steel is the thinnest and what is the thickest?
What is 38/40 for thinnest and 18 for the thickest?
What can happen if bacteria is present and you are using suture material that has high capillarity?
What is retain and spread infection by means of suture material?
Sutures with low capillarity are preferred in procedures with risk of infection.
Low capillarity sutures are nylon or polypropylene
